Kamen Rider Series/Heisei Series Phase 2

File:Heisei Kamen Rider Series Phase 2.jpg
**Heisei Kamen Rider Series Phase 2** (平成仮面ライダーシリーズ第2期, *Heisei Kamen Raidā Shirīzu Dai Ni-Ki*?), is a subsection of the Heisei era of the *Kamen Rider Series* that comprises its second half.

The Heisei Phase 2 is specifically used to refer to the post-*Decade* time period, the second half of the Heisei Era, with *Kamen Rider Decade* having been the 10th Anniversary Heisei *Kamen Rider* show, and *Kamen Rider Zi-O* having been the 20th Anniversary Heisei *Kamen Rider* show.

After *Decade*, and due to *Kamen Rider: Dragon Knight*, "Kamen Rider" became the official term for Riders while pre-Decade Riders have been called "Masked Rider" in official localization releases due to *Saban's Masked Rider*. Merchandise such as the S.H. Figuarts toyline, as well as official labels within in-series content, gives since then the distinction. Phase 2 of the Heisei series started with Decade's successor, *Kamen Rider W*, which premiered in September 2009 and ended in August 2010.

On April 1, 2016, the original net series *Kamen Rider Amazons* was aired. It marks the Heisei Era's first time since Faiz that the franchise has gone back to a darker and more adult-oriented style of storytelling, resulting in a rating of R15+. However, it is only available on Amazon Prime. A second season was released in 2017, and a movie that concludes the series was released in theaters in 2018.

## Heisei Phase 2 trends

* In general
* From Wizard onwards
* From Gaim onwards
* From Drive onwards
* From Build onwards

* The Heisei Phase 2 era has a differing broadcast schedule for its shows with the schedule of the first half of the Heisei era. This change had been brought about by the shortened episode count of *Kamen Rider Decade*. The first series of the Heisei revival, *Kamen Rider Kuuga* premiered in January 2000, and ended in January 2001, being succeeded by *Kamen Rider Agito* the week after. From then on, every Heisei show until the start of the Heisei Phase 2 era started in late January (or in *Ryuki's* case, early February) and ended in January of the next year. However, *Kamen Rider Decade*, which premiered in January 2009, was slated as having only 30 episodes as stated by Masahiro Inoue in an interview in the March 2009 issue of Kindai Magazine. A subsequent interview in Otonafami magazine confirmed that only 30 episodes were filmed, with 31 episodes airing in total. Thus, *Decade* ended in late August (the 30th) and *W* started in early September (the 6th), so Heisei Phase 2 shows then were ending on the last Sunday of August and started on the first Sunday of September; though that because of *Wizard* having 53 episodes, the series would since then end on the last Sunday of September and the first episode of the new series starts on the first Sunday in October. This trend would stop with *Ex-Aid* having 45 episodes, thus going back the the prior early September-late August run.
* With this new broadcast schedule, the summer movie of every show now premieres during the final weeks of said show and only around a month before the arrival of the new series. Thus, from Kamen Rider Double's introduction in *Kamen Rider Decade: All Riders vs. Dai-Shocker* (August 2009) (with the exception of Kamen Rider Gaim and Kamen Rider Drive), the Rider of the upcoming show makes his "early-bird cameo". This introduction features the new Rider helping out the current (soon to depart) Rider.
	+ Even though Kamen Rider Decade is not a Phase 2 Rider and did not appear in the previous Rider's series, he is the first primary Heisei Rider to make an "early-bird cameo" in a special (even if it actually aired after the premiere of the *Decade* series), which later foreshadows most of the primary Phase 2 Riders appearing in a summer movie.
	+ Kamen Rider Gaim's "early-bird cameo" is unique in that instead of making his debut in Wizard's summer movie, he appeared in his two-part epilogue special.
	+ Kamen Rider Drive is the only primary Phase 2 Rider, and the first primary Kamen Rider since Decade, who does not make a cameo appearance in his predecessor's series. *Kamen Rider Saber* in the Reiwa Era would become a new example.
* All of the summer movies have the main Rider using all of their forms that debut in the television series, including a movie-exclusive form that is introduced in the movie.
	+ *Kamen Rider W*: CycloneJokerGoldXtreme
	+ *Kamen Rider OOO*: Burakawani Combo
	+ *Kamen Rider Fourze*: Meteor Fusionstates
	+ *Kamen Rider Wizard*: Infinity Dragon
	+ *Kamen Rider Gaim*: Black Jimber Arms
	+ *Kamen Rider Drive*: Super Dead Heat Drive & Type Special
	+ *Kamen Rider Ghost*: Darwin Damashii
* With the exception of Double, each Hyper Battle DVD also has the main Rider gaining access to a form that is only exclusive to said special.
	+ *Kamen Rider OOO*: Takagaruba, Takatoragaru, & Takatorazou
	+ *Kamen Rider Fourze*: Rocket Drill States
	+ *Kamen Rider Wizard*: Beast Mantle
	+ *Kamen Rider Gaim*: Fresh Orange Arms
	+ *Kamen Rider Drive*: Type High Speed, Type High Speed Vegas, & Type High Speed Flare
	+ *Kamen Rider Ghost*: Ikkyu Damashii
	+ *Kamen Rider Ex-Aid*: Bike Action Gamer Level 0
	+ *Kamen Rider Build*: KumaTV Form
	+ *Kamen Rider Zi-O* is unique in that it is instead the secondary Rider who gains the Hyper Battle form (in this case, BiBill Geiz).
* Another result of the new broadcast schedule is that while the bulk of early Heisei series ran alongside one particular *Super Sentai* series, Heisei Phase 2 shows find themselves paired up with two Sentai shows across their run, the first half of the series airs alongside the second half of their first Sentai partner, while the second half of the series airs alongside the first half of their second partner.
* The official translation of the *Kamen Rider Series*, as seen on the series' titles, was changed from "Masked Rider" (e.g. *Masked Rider Decade*) to "Kamen Rider" (e.g. *Kamen Rider W*).
* As started by *Kamen Rider W*, it is a recurring trend that only two Riders appear in the broadcast run: the Primary Rider and the Secondary Rider. Though, every series has had more new Riders appear through expanded universe material, particularly their own summer movies, which go on to appear again occasionally. The main series only deals with the Primary and Secondary Riders. This trend stopped in *Kamen Rider Wizard*, as each season after that would introduce more than two Riders throughout the course of the series, with *Gaim* and *Ex-Aid* starting off with multiple Riders from the beginning. Movie-exclusive Riders do not count.
	+ *Kamen Rider W*: Double & Accel (as well as Joker)
	+ *Kamen Rider OOO*: OOO & Birth (as well as Proto-Birth)
	+ *Kamen Rider Fourze*: Fourze & Meteor
* The transformation devices of Riders in the Heisei Phase 2 era are given consistent names, being referred to as "Drivers" (e.g. Doubledriver, OOO Driver, Fourze Driver, Wizardriver, Sengoku Driver, Drive Driver, Ghost Driver, Gamer Driver, Build Driver, and Ziku-Driver.). *Driver* was previously used to refer to the transformation gears of the Kamen Riders from *Kamen Rider 555* and *Kamen Rider Decade*. The "Driver" term may come from the fact that Transformation Belts had become a mean of using the powers of objects (Rider gimmicks).
	+ The Mage's Belt in *Kamen Rider Wizard*, the Mega Ulorder in *Kamen Rider Ghost* and the Gashat Gear Dual in *Kamen Rider Ex-Aid* are anomalous breaks in this trend.
* Each Heisei Phase 2 series has its own set of Collectible Devices, first seen with the Advent Cards in *Kamen Rider Ryuki*, with the recent tradition being kicked off by the Rider Cards of *Kamen Rider Decade*, which were used by Decade to access the power of previous Kamen Riders. As with Decade, the Heisei Phase 2 Kamen Riders use their collectible devices for various purposes, such as changing into their various forms, using special attacks, and other techniques. These collectible devices also work ***very*** well with merchandise, each set of collectibles has had their own "Legend Rider" range featuring the likenesses of previous Kamen Riders, some of which appear in the arcade game *Kamen Rider Battle: Ganbaride* and Movie War crossovers.
	+ *Kamen Rider W*: Gaia Memories
	+ *Kamen Rider OOO*: O Medals (Core Medals for OOO & Cell Medals for Birth)

	+ *Kamen Rider Zi-O*: Ridewatches
* Starting with Decade's Final Form Ride (Toyline) series, each Heisei Phase 2 season would have a toyline of figures which simulate a transformation gimmick unique to each season, commonly referred to by fans as "gimmick figures". Although there was a precursor with *Kamen Rider Kabuto*'s Cast Off Rider series, which simulated the Cast Off gimmick, gimmick figures in the Heisei Phase 2 era were much more prominent.
	+ *Kamen Rider Decade*: Final Form Ride (Toyline) series, which simulates Decade's Final Form Ride ability.
	+ *Kamen Rider W*: W Form Change series, which simulates Double's half-changes gimmick.
	+ *Kamen Rider OOO*: OOO Combo Change series, which simulates OOO's combo change ability.
	+ *Kamen Rider Fourze*: Fourze Module Change Series, which simulates Fourze's equipping of Astroswitch Modules.
	+ *Kamen Rider Wizard*: Wizard Action Please! series
	+ *Kamen Rider Gaim*: Arms Change series, which simulates the interchangeability of various Riders' Ride Wears and Armor Parts.
	+ *Kamen Rider Drive*: Tire Koukan series, which simulates the Tire and Signal Exchange abilities of Drive, Mach, and Chaser.
	+ *Kamen Rider Ghost*: Ghost Change series, which simulates the interchangeability of various Riders' Transients and Parka Ghosts.
	+ *Kamen Rider Ex-Aid*: Level UP Rider Series, which simulates the Riders' Level Up function.
	+ *Kamen Rider Build*: Bottle Change Rider Series, which simulates Build's Best Match changing gimmick.
	+ *Kamen Rider Zi-O*: Rider Kick's Figure Series, which simulates Zi-O's and Geiz's Armor Time gimmick. This line also includes Riders from past series as well. This line would later become the default gimmick figure line beyond Zi-O until the start of *Revice*.
* With the exception of Double and Ghost, each lead Rider has an Item Carrier for their Collectable Devices.

	+ *Kamen Rider Zi-O*: Ridewatch Holder & Ridewatch Daizer
* With the exception of Gaim, each Heisei Phase 2 series also has a set of Support Robots, which initially appeared in the form of the Disk Animals from *Kamen Rider Hibiki*, but became prominent in the Heisei Phase 2 era.
	+ *Kamen Rider W*: Memory Gadgets
	+ *Kamen Rider OOO*: Candroids
	+ *Kamen Rider Fourze*: Foodroids
	+ *Kamen Rider Wizard*: PlaMonsters

	+ *Kamen Rider Ex-Aid*: Gamers
	+ *Kamen Rider Build*: Cross-Z Dragon
	+ *Kamen Rider Zi-O*: Taka Watchroid & Kodama Suika Arms

	+ *Kamen Rider Ghost*: Captain Ghost
	+ *Kamen Rider Ex-Aid*: Kamen Rider Lazer Bike Gamer Level 2 & Maximum Gamer Level 99
	+ In *Kamen Rider Build*, it is instead the villains who utilize Guardians as a piece of mecha (particularly in their Union State).
	+ *Kamen Rider Zi-O*: Time Mazine
* With the exception of *Build*, each Heisei Phase 2 series has a piece of arsenal that can assume at least three different modes.
	+ *Kamen Rider W*: The Hardboilder can also assume its Hardturbuler and Hardsplasher modes, aside from its default motorcycle mode.
	+ *Kamen Rider OOO*: Aside from its Machine Vendor and Machine Bike modes, the Ridevendor also becomes the ToRidevendor when combined with the Toracandroid.
	+ *Kamen Rider Fourze*: The Powerdizer, aside from its default robot mode, can also assume Vehicle Mode and Tower Mode.
	+ *Kamen Rider Wizard*: Aside from its default Phantom form, Wizardragon can combine with the Machinewinger to form Winger Wizardragon. When the Kick Strike Ring is used, Winger Wizardragon becomes the Strike Phase. It can also become the Axcalibur when Wizard accesses Infinity Style.
	+ *Kamen Rider Gaim*: Suika Arms can interchange between its Yoroi, Oodama, and Gyro modes.
	+ *Kamen Rider Drive*: Tridoron can change its form based on Drive's three main forms: Type Speed, Type Wild, and Type Technic.

	+ *Kamen Rider Ex-Aid*: The Gashacon Bugvisor (shooter, chainsaw, and Driver) and the Gashacon Key Slasher (sword, axe, and gun). Ex-Aid's Bike Gamer was initially a Kamen Rider who had access to Level 1, Level 2, Level 3 and Level 5 forms.
	+ *Kamen Rider Zi-O*: The Zikan Despear has three modes: spear, scythe and cane.
* With the exception of OOO (who instead frequently proclaims the battle cry **"Seiya!"**), each lead Rider has their own unique pre-battle catchphrase.
	+ *Kamen Rider W*: **"Now, count up your sins!"**
	+ *Kamen Rider Fourze*: **"Space is here! Kamen Rider Fourze! Let's settle this one-on-one!"**
	+ *Kamen Rider Wizard*: **"Now, it's showtime!"**
	+ *Kamen Rider Gaim*: **"This is my stage now!"**

	+ *Kamen Rider Build*: **"The laws of victory have been set!"**
	+ *Kamen Rider Zi-O*: **"I think I can do this now!"**
* With the exception of Baron, Specter (who says his catchphrase **"I'll show you my way of life!"** prior to finishing off an enemy), and Geiz; the Secondary Riders also have their own unique pre-battle catchphrase.
	+ Kamen Rider Accel: **"Now, let's break through!"**
	+ Kamen Rider Birth: **"Now, time to cash in!"** (Date only)
	+ Kamen Rider Meteor: **"I will decide your fate!"**

	+ Kamen Rider Brave: **"Commencing Bugster removal operation."**
	+ Kamen Rider Cross-Z: **"I feel unbeatable at this moment!"**
* The lead Rider usually has unique laws involving his forms:
	+ The second new form he obtains debuts in the first part of a two episode arc instead of the second (e.g. OOO's Latorartar Combo, Fourze's Firestates, Wizard's Hurricane Dragon, & Drive's Type Technic).
	+ The Super Form, or a version of the Super Form (or in Ghost and Build's cases the upgrade form), first debuts in the Movie War film, and then usually appears around episode 20 of the series, with Fourze, Gaim, and Drive being the exceptions.
	+ The Final Form debuts in episode 32, except for Wizard's Infinity Style (which debuted in episode 31) and Drive's Type Tridoron (which debuted in episode 33), followed by Ghost Mugen Damashii (which was briefly seen in episode 33 and made its full debut in episode 34), Ex-Aid Muteki Gamer (which debuted in episode 36), Build Genius Form (which debuted in episode 39), and GrandZi-O (which was briefly seen in episode 39 and made its full debut in episode 40).
* With the exception of Double, the lead Rider's forms have some sort of title.

* The lead Rider and secondary Rider(s) display some kind of cross-compatibility.
	+ *​Kamen Rider W*: Kamen Rider Double CycloneAccelXtreme was hypothesized to be possible if Ryu Terui took Shotaro Hidari's place as Double.
	+ *Kamen Rider OOO*: Eiji Hino transforms into Kamen Rider Birth in *Kamen Rider OOO Wonderful: The Shogun and the 21 Core Medals*.
	+ *Kamen Rider Fourze*: Kamen Rider Meteor is able to use Fourze's Circle Astroswitches to activate finishers.

	+ *Kamen Rider Wizard*: Exclusively in the Hyper Battle DVD, Kamen Rider Wizard accesses Falco Mantle and Beast Mantle using Beast's Falco and Buffa Wizard Rings.
	+ *Kamen Rider Gaim*: All Armored Riders can utilize any Lockseed compatible with their Driver. This has been demonstrated by Gaim using Banana Arms, Donguri Arms, and Durian Arms, as well as Baron, Ryugen, and Zangetsu interchanging Ichigo Arms, Melon Arms, Kiwi Arms, Banana Arms, Pine Arms, Budou Arms, and Mango Arms, along with Suika Arms being used by multiple Riders throughout the series. Additionally, Gaim's Kiwami Arms can summon any Arms Weapon.
	+ *Kamen Rider Drive*: Multiple Shift Cars and Signal Bikes combine the powers of different Riders.
		- The Shift Deadheat Car allows Drive and Mach to access a form that combines both of their powers.
		- Mach uses the Signal Chaser to merge his power with Chaser's.
		- The Tridoron Key is used in the Mach Driver Honoh to access Drive's Super Dead Heat form, which is themed after Mashin Chaser.
		- In the absence of the Drive Driver, Drive has used the Mach Driver Honoh to become Dead Heat Drive.
		- The Shift Ride Crosser Car allows Mach to access a form that combines his power with Chaser's.
	+ *Kamen Rider Ghost*: Ghost, Specter, and Necrom can use any of each other's Eyecons, as seen when Specter accessed Edison Damashii and Necrom Damashii, and Ghost accessed Toucon Houdini Damashii. Ghost's Grateful Damashii also combines the power of all 15 Eyecons.
	+ *Kamen Rider Ex-Aid*
		- Drago Knight Hunter Z is a Rider Gashat shared by the main four Riders. They each can use it on their own to gain all the armor of the Hunter Gamer, or it can duplicate to be used between multiple Riders and access stronger Rider-specific forms.
		- The Gashat Gear Dual β is a device shared between Brave and Snipe to access their own Level 50 forms.
		- On multiple occasions a Rider has used another's Gashat to activate a finisher.
		- If a Rider or Ride-Player possesses a Gashat tied to a Gashacon Weapon, they can use the weapon without having to activate the Gashat.
		- Kamen Rider Cronus has the ability to use any Gashacon Weapon, however, this has only been demonstrated while using the Gamer Driver instead of the Buggle Driver II.
		- Ex-Aid once stole the Gashacon Sword out of Brave's hands.
	+ *Kamen Rider Build*: The Dragon Fullbottle is used by Kamen Rider Build with the Lock Fullbottle to access KeyDragon Form, and is used by Kamen Rider Cross-Z to access his default form.
	+ *Kamen Rider Zi-O*: The Ridewatches based on the past Heisei Riders can be used by either Kamen Rider Zi-O or Kamen Rider Geiz.
* In every Heisei Phase 2 series, the Riders have some sort of nickname for their finishing attacks, which are announced by their transformation devices and various weapons.
	+ *Kamen Rider W*: Maximum Drive
	+ *Kamen Rider OOO*: Scanning Charge/Giga Scan/Putotyranno Hissatsu (OOO) & Cell Burst (Birth)
	+ *Kamen Rider Fourze*: Limit Break
	+ *Kamen Rider Wizard*: (Attack name) Strike

	+ *Kamen Rider Ex-Aid*: Critical (Attack name)
	+ *Kamen Rider Build*: Vortex (Attack name) (Build Driver), (Attack name) Break/Finish
	+ *Kamen Rider Zi-O*: Time (Attack name)
* In the Heisei Phase 2 shows, the lead Rider and the secondary Rider often have similar yet distinct powers, abilities, and themes. This trend began with *Kamen Rider Decade*, where both Riders used Rider Cards, with the difference between them being that Decade has a smaller selection of cards, but can transform into them with full access to their powers, while Diend has access to more cards, but can only summon copies of Riders without their full range of powers. This continues in each of the following series.
	+ *Kamen Rider W*: Kamen Rider Accel uses Gaia Memories in his own personal Driver to access a form with his own overarching theme (motorcycles).
	+ *Kamen Rider OOO*: Kamen Rider Birth expands the coin concept into a gashapon motif, expending cell medals to access his own built-in weapons.
	+ *Kamen Rider Fourze*: Kamen Rider Meteor uses his own Driver and Astroswitch to transform, expressing the space theme in the form of his meteor motif and ability to channel planets as weapons.
	+ *Kamen Rider Wizard*: Kamen Rider Beast uses his own Driver and Wizard Rings to transform, using the mythical Chimera to convey an animal theme along with the magic theme.
	+ *Kamen Rider Gaim*: Each Rider bears their own warrior motif (samurai, knight, Chinese soldier, gladiator, etc.) and uses their own Lockseeds to gain unique fruit armor.
	+ *Kamen Rider Drive*: Kamen Rider Mach uses his own Driver, with Signal Bikes instead of Shift Cars, to access his bike-themed Rider form and street sign themed abilities.
	+ *Kamen Rider Ghost*: Kamen Rider Specter's design is a minor variation on Ghost's, using his own personal Eyecon and other Heroic Eyecons to access his own forms.
	+ *Kamen Rider Ex-Aid*: Secondary Riders use other games to transform, each with their own themes and weapons.
	+ *Kamen Rider Build*: Kamen Rider Cross-Z uses his own device to adapt the Build Driver's two slots into one, and transforms with the Dragon Fullbottle, also used by Build to access KeyDragon Form.
	+ *Kamen Rider Zi-O*: While Kamen Rider Zi-O's forms and arsenal are themed after katakana, Geiz's forms and arsenal are conversely themed after hiragana. Geiz can also use the Ridewatches of supporting Riders for finishing attacks, though no corresponding Rider Armor has been revealed for them.
* Having previously been the suit actor of the majority of primary riders in the early Heisei era (with the exceptions being Kuuga and Hibiki, who are instead suit acted by Kenji Tominaga and Makoto Ito, respectively), Seiji Takaiwa has served as the suit actor for every Primary Rider in the Heisei Phase 2 era.
	+ Fighting alongside Takaiwa is Eitoku who, starting with Kamen Rider Diend in *Decade*, has gone on to be the suit actor for every secondary Heisei Phase 2 Rider, except for Beast, Mach, Specter, and Brave Level 2 all of whom are suit-acted by Jun Watanabe, as well as Geiz, who is instead suit-acted by Yuya Nawata.
* A resurgence of crossovers, as the early Heisei era rarely featured crossovers between series (one rare example is the Hyper Battle DVD *Kamen Rider Ryuki: Ryuki vs Kamen Rider Agito*). *Kamen Rider Den-O & Kiva: Climax Cop* was the first Heisei crossover movie (April 2008), though that it was largely due to the popularity of *Kamen Rider Den-O*. Being an anniversary series, the very premise *Kamen Rider Decade* involved various elements of the *Kamen Rider Series* coming together.
	+ The Movie War series, starting with *Kamen Rider × Kamen Rider W & Decade: Movie War 2010* (December 2009), each Heisei Phase 2 series has a Movie War crossover with the previous series, premiering in December, somewhere in between episodes 10 and 15 of the current series. Just as the summer movies introduce the primary Rider of the new series, the Movie War features an "early-bird cameo" by the Secondary Rider of the current series. As with the primary Rider's introduction in the summer movie, the new secondary Rider appears in costume only, however their were chances that the user of the secondary Rider would appear in both civilian and Rider form. *Kamen Rider × Kamen Rider OOO & W feat. Skull: Movie War Core* (December 2010) featured a crossover between Kamen Riders Double and OOO, the first two primary riders of the Heisei Phase 2 era, followed by *Kamen Rider × Kamen Rider Fourze & OOO: Movie War Mega Max* (December 2011), which also featured Double and the Seven Legendary Riders as well as Fourze and OOO, teaming the first three Heisei Phase 2 riders with the seven original Showa riders. This is set to be topped by the *Kamen Rider × Kamen Rider Wizard & Fourze: Movie War Ultimatum* (December 2012), which featured Kamen Rider Wizard teaming up with not just Fourze, but all three of the previous Heisei Phase 2 primary Riders and their secondary Riders as well.
		- Other theatrical Heisei Phase 2 crossovers include the Kamen Rider Series 40th Anniversary movie, *OOO, Den-O, All Riders: Let's Go Kamen Riders*, and the first crossover movie with *Super Sentai*, *Kamen Rider × Super Sentai: Super Hero Taisen*.
* Foundation X, which was first introduced as the "evil organization" of *Kamen Rider W*, continues to have a (albeit reduced) presence in the other Heisei Phase 2 Kamen Rider shows, having appeared in episodes of *Kamen Rider Fourze* and as the villains of *Kamen Rider × Kamen Rider Fourze & OOO: Movie War Mega Max*, and in *Kamen Rider Fourze The Movie: Everyone! Let's Feel the Universe!*. Foundation X seemed to have disappeared as of *Kamen Rider Wizard*, but after a cameo in *Kamen Rider Brave: ~Let's Survive! Revival of the Beast Rider Squad!~*, they returned as a villainous influence in *Kamen Rider Heisei Generations Final: Build & Ex-Aid with Legend Riders*. Their presence is reminiscent of the influence the Great Leader (originally the Great Leader of Shocker) had on later evil organizations in the Showa era. In Foundation X's footsteps, seasons from *Wizard* onward have had evil organizations exerting villainous influence in some capacity:
	+ *Kamen Rider Gaim*: Yggdrasill Corporation
	+ *Kamen Rider Drive*: National Bureau of Defense and Neo Shade
	+ *Kamen Rider Ghost*: Deep Connect
	+ *Kamen Rider Ex-Aid*: Genm Corp. and Next Genome Institute
	+ *Kamen Rider Build*: Faust and Namba Heavy Industries Ltd.
* Each Heisei Phase 2 era villain group has their own Henchmen squad.
	+ *Kamen Rider W*: Masquerade Dopants
	+ *Kamen Rider OOO*: Kuzu Yummies
	+ *Kamen Rider Fourze*: Stardust Ninja Dustards
	+ *Kamen Rider Wizard*: Ghouls

	+ *Kamen Rider Ex-Aid*: Bugster Virus
	+ *Kamen Rider Build*: Guardians
	+ *Kamen Rider Zi-O*: Several Another Riders can summon the villain henchmen faced by their Kamen Rider counterparts.
* Each series' monsters are either summoned or transformed by a Collectible Device, usually another version of the main hero's Collectible Devices. Wizard is an exception, as only the Ghouls are summoned by Magic Stones, as well as Build's Smash being transformed by the Steam Blade's Devil Steam attack (although, in a reversal, their essences are retrieved in Empty Bottles transforming them into Smash Bottles which can transform a former victim back into a Smash).
	+ *Kamen Rider W*: Dopant Memories
	+ *Kamen Rider OOO*: Cell Medals
	+ *Kamen Rider Fourze*: Zodiarts Switch

	+ *Kamen Rider Ex-Aid*: Proto Gashats
	+ *Kamen Rider Build*: Smash Bottles
	+ *Kamen Rider Zi-O*: Anotherwatches
* Each series features various sets of collectible devices with a specific number. The numbers are mostly to serve as the plot device for the scenario. Some of them are used to develop more devices for power up forms.
	+ *Kamen Rider W*: 26 T2 Gaia Memories
	+ *Kamen Rider OOO*: 8 types of Core Medals
	+ *Kamen Rider Fourze*: 40 Astro Switches and 12 Horoscopes Switches
	+ *Kamen Rider Wizard*: 4 elements of Transformation Wizard Rings + Dragon Wizard Rings and 13 Rider Rings

	+ *Kamen Rider Zi-O*: 20 Ridewatches
* As a tribute to Kamen Rider Stronger and Kuuga Rising Form's electric attributes, some of the seasons feature forms and items which produces electric effects.
	+ *Kamen Rider OOO*: Gatakiriba Combo/Kuwagata Medal
	+ *Kamen Rider Fourze*: ElekStates
	+ *Kamen Rider Wizard*: Thunder Wizard Ring
	+ *Kamen Rider Drive*: Type Deadheat/DeadHeat Mach
	+ *Kamen Rider Ghost*: Edison Damashii
* Riders after Fourze and before Drive have their own title rather than Kamen Rider in their own universe or timeline. This first happened in Hibiki, where the Riders were being called Oni to match the heavy Japanese mythology-theme of the series.
	+ *Kamen Rider Wizard*: Magicians
	+ *Kamen Rider Gaim*: Armored Riders & Genesis Armored Riders
* With the exception of OOO, Fourze, Ex-Aid, Build, and Zi-O, the second-to-last (or in Wizard's case, third-to-last) episode of each Heisei Phase 2 series is the conclusion to its main storyline while the actual finale is an epilogue.
	+ *Kamen Rider W*: *The Abandoned U/Eternal Partners* (#48 of 49)
	+ *Kamen Rider Wizard*: *The Last Hope* (#51 of 53)
	+ *Kamen Rider Gaim*: *Fate's Victor* (#46 of 47)
	+ *Kamen Rider Drive*: *Who Will You Entrust the Future to, My Friend?* (#47 of 48)
	+ *Kamen Rider Ghost*: *Infinity! Power of Humanity!* (#49 of 50)
* With the exception of Gaim, the finale of each Heisei Phase 2 series contains a link to the next series.
	+ *Kamen Rider W*: In *The Abandoned U/Eternal Partners*, which was technically the second-to-last episode but served as the finale (the true final episode took place one year in the future), Foundation X scraps their research on Gaia Memories and instead takes an interest in O Medals.
	+ *Kamen Rider OOO*: In *Finale: The Medals of Tomorrow, Underwear, and Arms Held*, Kengo Utahoshi and Yuki Jojima appear with an Astroswitch. This is the first time characters from the next series are seen.
	+ *Kamen Rider Fourze*: In *Final Episode: Youthful Galaxy*, Kamen Rider Wizard himself, Haruto Soma, appears out of costume wearing his Flame Style Wizard Ring.
	+ *Kamen Rider Wizard*: *The Kamen Rider Rings* and *Neverending Story* is a two-part crossover with all fifteen Heisei/Heisei Phase 2 main Riders, including Gaim.
	+ *Kamen Rider Drive*: Like Gaim, Ghost makes an appearance in Drive's last two episodes.
	+ *Kamen Rider Ghost*: Kamen Rider Genm makes an appearance in Ghost's last two episodes with Ex-Aid also appearing in Ghost's final episode.
	+ *Kamen Rider Ex-Aid* is unique as although Kamen Rider Build makes an appearance in Ex-Aid, he only appears in *Ex-Aid*'s second-to-last episode, which comes before the actual finale.
	+ *Kamen Rider Build*: In the finale, after the two worlds are merged, Sento Kiryu finds the Cross-Z Ridewatch in his possession.
	+ *Kamen Rider Zi-O*: In the closing screen of the finale, it features the Zero-One Ridewatch. This is the only time the link is in the closing screen rather than the actual episode itself.
* Each Heisei Phase 2 series has had an update to the video game *Kamen Rider: Climax Heroes*, which was first released for *Kamen Rider Decade* and the 10th anniversary of the Heisei Kamen Rider Series. These initially had the title format of *Kamen Rider Climax Heroes (show name)*, but *Kamen Rider Wizard* subverted that trend and *Kamen Rider Gaim* doesn't have its own *Climax Heroes*, as the fighting game series is replaced by a *Dynasty Warriors* like game called *Kamen Rider Battride War* after the last *Climax Heroes* since the appearance of *Kamen Rider Wizard*. Ghost, however, brought back the Battride War series in the form of *Kamen Rider: Battride War Genesis*, while Build brought back the Climax Heroes series in the form of *Kamen Rider: Climax Fighters*. Drive and Ex-Aid are the only two seasons to have no games from either game series produced.
	+ *Kamen Rider W*: *Kamen Rider: Climax Heroes W*
	+ *Kamen Rider OOO*: *Kamen Rider: Climax Heroes OOO*
	+ *Kamen Rider Fourze*: *Kamen Rider: Climax Heroes Fourze*
	+ *Kamen Rider Wizard*: *Kamen Rider: Super Climax Heroes* and *Kamen Rider: Battride War*
	+ *Kamen Rider Gaim*: *Kamen Rider: Battride War II*
	+ *Kamen Rider Ghost*: *Kamen Rider: Battride War Genesis*
	+ *Kamen Rider Build*: *Kamen Rider: Climax Fighters*
	+ *Kamen Rider Zi-O*: *Kamen Rider: Climax Scramble Zi-O*
* Each Heisei Phase 2 series features pertinent ally characters with a mysterious past that is linked to the main villains of the show. Most of them are all killed before their series concludes, but come back to life some time later, with the exception of Ankh and Koyomi, as they were technically aren't "alive" before the series started. However, Ankh was shown to have been possibly revived in the future as seen in *Movie War Mega Max*, before making a full (albeit temporary) return in *Kamen Rider Heisei Generations Final: Build & Ex-Aid with Legend Riders*. There is a rare exception where Mai as Woman of the Beginning was not killed in the traditional sense.
	+ *Kamen Rider W*: Raito "Philip" Sonozaki
	+ *Kamen Rider OOO*: Ankh
	+ *Kamen Rider Fourze*: Kengo Utahoshi
	+ *Kamen Rider Wizard*: Koyomi Fueki & Wizardragon
	+ *Kamen Rider Gaim*: Woman of the Beginning
	+ *Kamen Rider Drive*: Krim Steinbelt & Kiriko Shijima
	+ *Kamen Rider Ghost*: Sennin & Yurusen
	+ *Kamen Rider Ex-Aid*: Poppy Pipopapo
	+ *Kamen Rider Build*: Ryuga Banjou, Takumi Katsuragi & Vernage
	+ *Kamen Rider Zi-O*: Tsukuyomi
* Each Heisei Phase 2 series has a Female Kamen Rider, starting with Decade's Kamen Rider Kiva-la. *Build* is the only season not to feature one.
	+ *Kamen Rider W*: Akiko Narumi (dream only)
	+ *Kamen Rider OOO*: Erika Satonaka (Net Movie only)
	+ *Kamen Rider Fourze*: Nadeshiko Misaki
	+ *Kamen Rider Wizard*: Mayu Inamori & Koyomi Fueki (Movie War only)
	+ *Kamen Rider Gaim*: Yoko Minato
	+ *Kamen Rider Drive*: Kiriko Shijima (Special DVD only)
	+ *Kamen Rider Ghost*: Jey (Summer Movie only) & Alia
	+ *Kamen Rider Ex-Aid*: Poppy Pipopapo & Nico Saiba
	+ *Kamen Rider Zi-O*: Tsukuyomi
* Each Heisei Phase 2 series features ally characters who serve as primary comic relief characters.
	+ *Kamen Rider W*: Mikio Jinno, Shun Makura, Watcherman & Santachan
	+ *Kamen Rider OOO*: Kousei Kougami & Erika Satonaka
	+ *Kamen Rider Fourze*: Chuta Ohsugi
	+ *Kamen Rider Wizard*: Shigeru Wajima & Shunpei Nara
	+ *Kamen Rider Gaim*: Kiyojiro Bando & Iyo
	+ *Kamen Rider Drive*: Jun Honganji & Kyu Saijo
	+ *Kamen Rider Ghost*: Onari Yamanouchi, Sennin & Yurusen
	+ *Kamen Rider Ex-Aid*: Haima Kagami
	+ *Kamen Rider Build*: Hokuto Sanbagarasu
	+ *Kamen Rider Zi-O*: Junichiro Tokiwa
* Each Secondary Rider generally has a more major role in the series in the Heisei Phase 2 era than the previous Secondary Riders, usually starting out as anti-heroes but then working together with the Primary Rider later on in the series.
	+ Only Kamen Rider Birth & Cross-Z break this trend, with Birth being a generally heroic Rider from the start and Cross-Z being a character who was a helpful ally of the protagonist from episode 1.
* Usually, the Secondary Rider's Final Form debuts before the lead Rider's Final form.
	+ *Kamen Rider OOO*: Birth·Day debuted 6 episodes before OOO Putotyra Combo.
	+ *Kamen Rider Fourze*: Meteor Storm debuted 4 episodes before Fourze Cosmicstates.
	+ *Kamen Rider Wizard*: Beast Hyper debuted a mere 2 episodes before Wizard Infinity Style.
	+ *Kamen Rider Ghost*: Deep Specter debuted 6 episodes before Ghost Mugen Damashii.
	+ *Kamen Rider Build*: Cross-Z Magma debuted 8 episodes before Build Genius Form.
	+ *Kamen Rider Zi-O*: GeizRevive debuted 13 episodes before GrandZi-O.
		- However, there are a few exceptions to this:
			* AccelTrial appeared after Double CycloneJokerXtreme, similarly to the Heisei Phase 1 Riders.
			* Baron and Mach both received their final forms only in the final few episodes of their respective seasons.
			* Brave Legacy Gamer Level 100 debuted one episode after Ex-Aid Muteki Gamer.
* With the exception of OOO, Gaim, Drive, Ghost, and Ex-Aid (OOO instead evolving his default Main Form, Tatoba Combo, into his second Final Form, Super Tatoba Combo), each lead Rider evolves their Final Forms into Extra Final Forms in the Summer Movie, while Fourze and Wizard evolve their Extra Final Forms into Ultimate Forms in the Movie War films.
	+ *Kamen Rider W*: Double's CycloneJokerXtreme evolves into CycloneJokerGoldXtreme.
	+ *Kamen Rider Fourze*: Fourze's Cosmicstates evolves into Meteor Fusionstates by combining with Meteor, then into Meteor Nadeshiko Fusionstates by combining with Nadeshiko.
	+ *Kamen Rider Wizard*: Wizard's Infinity Style evolves into Infinity Dragon, then into Infinity Dragon Gold.
	+ *Kamen Rider Zi-O*: Zi-O's OhmaForm is an evolution of the power of Ohma Zi-O.
* Each series had lasted at least 47 episodes on average. *Kamen Rider Wizard* had 53, making this series the longest of all the Heisei Rider series. By contrast, *Kamen Rider Gaim* had exactly 47, making this series the shortest of all the Heisei Phase 2 Rider series at that time, if only barely qualifying. This record was broken by *Kamen Rider Ex-Aid*, which had only 45 episodes.
* Starting with the premiere of *Kamen Rider × Super Sentai: Super Hero Taisen* in 2012, the Rider series draw a greater connection with their rival franchise *Super Sentai*; furthered with the introduction of a TV special combining both franchises from *Gaim*. This was originally done prior with the World of Shinkenger cross-over during *Kamen Rider Decade* where the current Rider and Sentai squads encountered each other in a two-part story that primarily aired in KR but spilled over into several Sentai episodes around the same time. Each of these movies generally feature a combination between a Sentai mecha and a Rider's device. In the third Taisen series, Den-O is the one who rides the Sentai mecha, instead of Gaim, which is also making him the first Phase 1 Heisei Rider to do so.
	+ *Tokumei Sentai Go-Busters*: Rocket Drill Go-Buster Oh
	+ *Zyuden Sentai Kyoryuger*: Kyoryuzin Miracle Combination
	+ *Ressha Sentai ToQger*: ToQ-Oh Kyoryuzin feat. DenLiner
	+ *Shuriken Sentai Ninninger*: Shurikenjin Tridoron
	+ *Kamen Rider Ghost* and *Doubutsu Sentai Zyuohger* break the trend as the Taisen film was replaced with a Kamen Rider anniversary film and as such did not feature a combination. Instead, it reverted back to the traditional crossover episodes similar to Decade and Shinkenger.
	+ Though *Kamen Rider Ex-Aid* and *Uchu Sentai Kyuranger* reverted back to the traditional Taisen film format, the endgame only had Ex-Aid Maximum Gamer Level 99 grow gigantic to match KyurenOh's size, and did not feature a combination.
	+ Due to the cancellation of the Taisen series, it is likely that future Super Hero Time pairings (starting from *Kamen Rider Build* and *Kaitou Sentai Lupinranger VS Keisatsu Sentai Patranger*) will not feature any more crossovers.
* The main Rider will have some sort of disaster befall them before attaining the Final Form. This began since *Kamen Rider Decade*.
	+ *Kamen Rider Decade*: Tsukasa was unable to use any of his Rider Cards in the World of Negatives as they were all blacked out.
	+ *Kamen Rider W*: Due to Philip's body evolving, Shotaro is unable to keep up with him and thus unable to transform into Double.
	+ *Kamen Rider OOO*: Five of the Purple Core Medals enter Eiji's body, destroying any desire that Eiji has left.
	+ *Kamen Rider Fourze*: Meteor kills Gentaro as a part of a deal with the Aries Zodiarts in order to revive his friend Jiro.
	+ *Kamen Rider Wizard*: Haruto loses his ability to use magic due to Legion entering his Underworld and destroying Wizardragon.
	+ *Kamen Rider Gaim*: Kouta is heavily injured and knocked out in a battle with Demushu.
	+ *Kamen Rider Drive*: Shinnosuke is killed by a blast from Freeze, who had just attained his Over Evolved.
	+ *Kamen Rider Ghost*: Takeru loses his life after the Ore Ghost Eyecon is shattered.
	+ *Kamen Rider Ex-Aid*: After reprogramming Parado, Emu loses the Genius Gamer M abilities, which are needed for the Hyper Muteki Gashat to work.
	+ *Kamen Rider Build*: After Evolto separates himself from Sento, Sento regains all of his memories as Takumi Katsuragi, but also loses his new memories as Sento.
	+ *Kamen Rider Zi-O*: After obtaining the GrandZi-O Ridewatch, Momotaros confiscates the Den-O Ridewatch he had just given to Sougo and causes the former Ridewatch to fade from existance, after being told by Yuto and Deneb that Sougo would become the future Demon King.
* Halfway through the show, new kinds of monsters are introduced, usually a higher-up of the previous monsters or attained through a different source of evolution.
	+ *Kamen Rider Double* didn't introduce any new monsters during the series' run but the summer movie did introduce Dopants that are created through the T2 Gaia Memories ability transform anyone with the right compatibility without the use of a Living Connector.
	+ *Kamen Rider OOO* had Giru the Kyouryu Greeed and its Yummies which are created through the use of objects, although they appeared in OOO's Movie War they would make their series appearance through Kiyoto Maki and Eiji Hino who briefly became an alternate Kyouryu Greeed.
	+ *Kamen Rider Fourze* had the Horoscopes.
	+ *Kamen Rider Wizard* didn't have any sort of new monster, but rather, it had their leader and one of his generals be revealed to be large exceptions to how Phantoms are born.
	+ *Kamen Rider Gaim* had the Over Lord Inves.
	+ *Kamen Rider Drive* had the Fusion Roidmudes and eventually the Over Evolved State.
	+ *Kamen Rider Ghost* had the Gamma Superior, the Gamma Ultima, and finally the Gammaizers.
	+ *Kamen Rider Ex-Aid* had the Collabos Bugsters, as well as various Bugsters returning with a higher Level.
	+ *Kamen Rider Build* introduced Hazard versions of various Smash.
	+ *Kamen Rider Zi-O* had Another Riders originate in 2019 rather than the year their Rider counterpart originally came from.

- Beside two main Riders, more Riders are introduced in the series since the appearance of Supporting Riders (Kamen Rider Proto-Birth) in *Kamen Rider OOO*.
	* *Kamen Rider Wizard*: Aside from Wizard & Beast, there is also Wiseman & 3 different Kamen Rider Mages.
	* *Kamen Rider Gaim*: Aside from Gaim & Baron, there is also Ryugen (Yomi), Zangetsu, Gridon, Kurokage, Bravo, Knuckle, Jam, the Kurokage Troopers, Zangetsu Shin, Duke, Sigurd, & Marika.
	* *Kamen Rider Drive*: Aside from Drive & Mach, there is also Chaser, Gold Drive, & Jun.
	* *Kamen Rider Ghost*: Aside from Ghost & Specter, there is also Necrom, Dark Necrom Pink and Dark Ghost.
	* *Kamen Rider Ex-Aid*: Aside from Ex-Aid & Brave, there is also Snipe, Lazer, Genm, Para-DX, Poppy, and Cronus.
	* *Kamen Rider Build*: Aside from Build & Cross-Z, there is also Grease, Rogue, Evol, and MadRogue.
	* *Kamen Rider Zi-O*: Aside from Zi-O & Geiz. there is also Woz and Tsukuyomi.

- Each series has a white-colored Rider (with the exception of *Ex-Aid*, (though Genm, referred as the Black Ex-Aid though he later assumes a form that is white in color and plays a similar role), *Build*, and *Zi-O* (though Tsukuyomi becomes a white Kamen Rider, she is never referred to as such)), specially referred to as white.
	* *Kamen Rider Wizard*: White Wizard (Kamen Rider Wiseman)
	* *Kamen Rider Gaim*: White Armored Rider (Kamen Rider Zangetsu)
	* *Kamen Rider Drive*: White Kamen Rider (Kamen Rider Mach)
	* *Kamen Rider Ghost* is a special case as Kamen Rider Necrom is only referred to as the "White Kamen Rider" in an episode title.

- Each series has a character who is the closest friend of the protagonist and a relative of the series' white Rider. Since *Ghost*, this trend is sometimes inverted where the white Rider is also a relative to one of the main antagonists.
	* *Kamen Rider Wizard*: Koyomi Fueki
	* *Kamen Rider Gaim*: Mitsuzane Kureshima
	* *Kamen Rider Drive*: Kiriko Shijima
	* *Kamen Rider Ghost*: The Fukami siblings were adopted by the royal Gamma family. This makes Makoto and Alain as blood brothers. On the other hand, Adel is Alain's older brother who frames him for his father's apparent death before killing Adonis for real.
	* *Kamen Rider Ex-Aid* is a special case, as Poppy Pipopapo is only indirectly related to the season's white-accented Kamen Rider (Genm Level X) through her connection with said Rider's mother.
	* *Kamen Rider Build* once again follows the trend with *Ex-Aid*, as Ryuga Banjo is revealed to be a possessing the same alien genetic makeup as Evolto. Evol's Black Hole Form also has white accents.
	* *Kamen Rider Zi-O*: Tsukuyomi, who became a Rider late in the series, is the younger sister of the main antagonist, Swartz.

- With the exception of Zi-O, each series has a mad and treacherous scientist who dedicated his life to research the series' monsters, and can transform into a Kamen Rider.
	* *Kamen Rider Wizard*: Sou Fueki (Kamen Rider Wiseman)
	* *Kamen Rider Gaim*: Ryoma Sengoku (Kamen Rider Duke)
	* *Kamen Rider Drive*: Tenjuro Banno (Kamen Rider Gold Drive)
	* *Kamen Rider Ghost* is a special case as while Igor is referred to as a mad scientist who researches the Gamma, he only transforms into a Kamen Rider-like monster (Gamma Superior Perfect). There is also Edith, a Gamma scientist, who secretly betrayed the Gamma in order to aid the Kamen Riders, and at one point transforms into Kamen Rider Dark Ghost.
	* *Kamen Rider Ex-Aid*: Kuroto Dan (Kamen Rider Genm), though his role leans slightly more towards a "Game Master" than an actual scientist. This role is later assumed by Masamune Dan, the true mastermind of the series.
	* *Kamen Rider Build*: In an unusual case, Takumi Katsuragi, an obsessive designer of nearly all technological tools of conflict in *Build*, while not being portrayed as an active Kamen Rider, is in fact Sento Kiryu, Kamen Rider Build himself.

- Each series has a red-colored villain general who can use heat power and become stronger when defeated. Up to Drive, and also later in Build, their role and importance gradually increase after each series.
	* *Kamen Rider Wizard*: Phoenix (He was defeated by the main Rider's Super Form)
	* *Kamen Rider Gaim*: Demushu (He was defeated by the main Rider's Final Form)
	* *Kamen Rider Drive*: Heart (He is the leading general and is stronger than the main Rider's Final Form)
	* *Kamen Rider Ghost*: While there is no recurring red villain general in the show, Gammaizer Fire does share some trends with this trope, as it has pyrokinesis and can resurrect itself after each defeat, even having first appeared briefly possessing Jabel. Adel also stated in Episode 33 that the Gammaizers become more powerful after every defeat.
	* *Kamen Rider Ex-Aid*: Initially, there was no recurring red villain general in the show. Graphite, however, later obtained a red form, making him fit for this trope. As well, he made a unique return from death prior to obtaining his red form, alluding to this trope's knack for becoming stronger when defeated.
	* *Kamen Rider Build*: Evolto (He is revealed to be the true villain of the show, having already begun his schemes since before the start of the series.)
	* *Kamen Rider Zi-O*: Swartz (Though the show has no red-colored villain as with *Ex-Aid*, he likewise orchestrated the events of the series. He transforms into Another Decade, who has the ability to control space-time and dimensions to his will.)

- Each series has a calm and calculative, but psychotic green-colored villain general. In contrast, their role and importance gradually decrease after each series up to Drive.
	* *Kamen Rider Wizard*: Gremlin, the manipulative usurper who was one of Wizard's final opponents.
	* *Kamen Rider Gaim*: Redyue, a treacherous Over Lord Inves who was a secondary villain.
	* *Kamen Rider Drive*: Brain, the comic relief of the Roidmude generals.
	* *Kamen Rider Ghost*: While there is no recurring green villain general in the show, Alain, the regular villain general since the beginning, can transform into a Kamen Rider with a green default form. He has gradually changed from a calculative villain to a fully heroic Kamen Rider. In contrast, Adel has become the more psychotic and calculative villain general in Alain's place, although he does not wear green.
	* *Kamen Rider Ex-Aid*: While Graphite was initially green, he doesn't fit into this trope. Instead, this role is fulfilled by Masamune Dan, who can transform into a green Kamen Rider.
	* *Kamen Rider Build*: While Nariaki Utsumi fulfills the qualities of being calm and calculative, he is rarely associated with the color green, instead transforming into a white and purple-accented Kamen Rider.
	* *Kamen Rider Zi-O*: White Woz, who was the first user of Kamen Rider Woz, a cunning manipulator who tried to goad Geiz into becoming GeizRevive in hopes of making his future come true that only lasted in the show's middle chunk.

- Each series' endgame has a character who defeats the main villain instead of the Primary Rider.
	* *Kamen Rider Wizard*: Gremlin
	* *Kamen Rider Gaim*: Redyue and Kaito Kumon
	* *Kamen Rider Drive*: Go Shijima
	* *Kamen Rider Ghost* broke this trend, as Ghost was the one who defeated all major antagonists in the series.
	* *Kamen Rider Ex-Aid*: Masamune Dan is a self-inflicted example of this, as he kills himself.
	* *Kamen Rider Build* once again breaks this trend, with Sento defeating Evolto.
	* *Kamen Rider Zi-O* once again broke the trend, with Sougo becoming Ohma Zi-O and defeating Swartz.

- Between their Main Forms and their Super Forms, all main Riders also have a set of forms that are upgraded from their base forms. In the toylines, all of these forms have the ability to somewhat interchange.
	* *Kamen Rider Wizard*: Dragon Styles. One Wizardragon part can be attached to each of the Dragon Styles.
	* *Kamen Rider Gaim*: Jimber Arms. All of the Jimber Arms share the same Armor Parts, which have four sides. Each side represents a respective Energy Lockseed.
	* *Kamen Rider Drive*: Type Dead Heat. Its helmet is designed to transform between Drive and Mach, although this is only for accuracy to the Tire Koukan figure series and never happens on-screen. Additionally, Type Dead Heat's tire burns out upon loss of control of the form.
	* *Kamen Rider Ghost*: Toucon Boost Damashii, which is an upgraded version of Ore Damashii. It can also don any Damashii used by the Ore Transient, as well as the three Damashii that debut for it.
	* *Kamen Rider Ex-Aid*: Most of Ex-Aid's forms fit this trope: The Level 3, 4, and 5 forms are all theoretically interchangeable between Riders; Level 5 in particular being an extra strong form that can have Rider-specific modes or its fully-armored single-Rider mode; and Mighty Brothers XX is a direct upgrade to Mighty Action X that can split into two Riders.
	* *Kamen Rider Build*: RabbitTank Sparkling is a direct upgrade to RabbitTank Form. While it features no unique transformation gimmicks, Build's true Super Forms, RabbitRabbit Form and TankTank Form, are armor attachments on top of RabbitTank Hazard Form.

- Besides the normal humanoid monsters, the main Riders also occasionally have to fight against giant CGI monsters. This was first featured in *Kamen Rider Hibiki*.
	* *Kamen Rider Wizard*: Inner Phantoms
	* *Kamen Rider Gaim*: Evolved Inves
	* *Kamen Rider Drive*: Giant Roidmudes
	* *Kamen Rider Ghost*: Giant Gamma & Gundari
	* *Kamen Rider Ex-Aid*: Bugster Union
	* *Kamen Rider Build*: Guardian (Union State)
	* *Kamen Rider Zi-O*: Another Kuuga

- Unlike the first three series in the Phase 2 era where the monster-of-the-week is directly created by the villain generals, the main villain groups since Wizard are loose and not well-organized.
	* *Kamen Rider Wizard*: All Phantoms, including the generals, were created at the same time.
	* *Kamen Rider Gaim*: Most Inves, including the generals, were randomly mutated from creatures eating the fruit of Helheim.
	* *Kamen Rider Drive*: All Roidmudes, including the generals, were created at the same time.
	* *Kamen Rider Ghost*: Most of the Gamma were randomly converted from humans whose souls were stolen into the Gamma world. It is later revealed that the Gamma were once humans from a village tribe in the past; the earliest Gamma (the Gamma royal family among others) being created at the same time.
	* *Kamen Rider Ex-Aid*: While all Bugsters are parts of the game *Kamen Rider Chronicle*, they don't have a real leader, and only act as how they were programmed.
	* *Kamen Rider Build*: Smash are nearly mindless in their destructive rampages, while the Faust that created them endures infighting at the hands of Blood Stalk.
	* *Kamen Rider Zi-O*: All Another Riders created by the Time Jackers are based on the 20 Heisei Kamen Riders, their appearances can be also derived to the monsters the Riders are associated to. Their creation leads to the erasure of that Rider from history. However, Another Riders created in the present prevents the Rider from losing their powers.

- Unlike Double and Fourze who don't have any weapons in their primary forms or OOO whose Medajalibur was received as a present by the Kougami Foundation, all of the main Riders have a default sidearm.
	* *Kamen Rider Wizard*: WizarSwordGun
	* *Kamen Rider Gaim*: Musou Saber
	* *Kamen Rider Drive*: Handle-Ken & Door-Ju
	* *Kamen Rider Ghost*: Gan Gun Saber
	* *Kamen Rider Ex-Aid*: Gashacon Breaker
	* *Kamen Rider Build*: Drill Crusher
	* *Kamen Rider Zi-O*: Zikan Girade

- While some advanced weapons in the previous three series (Double's Prismbicker, OOO's Taja Spinner, and Fourze's Barizun Sword) can be loaded with different Collectible Devices to unleash different effects, the ability to use Collectible Devices together with the main Rider's primary weapon has become a standard since Wizard. Ghost is the only season to break this trend, although the series still has weapons that utilize collectible devices (Sunglasseslasher, Gan Gun Catcher).

- Unlike Double, OOO, Fourze, Build and Zi-O whose default Main Forms consist of cold/neutral colors, the rest of the main Riders from Wizard to Ex-Aid have warm colors for their default Main Forms.
	* *Kamen Rider Wizard*: Red
	* *Kamen Rider Gaim*: Orange
	* *Kamen Rider Drive*: Red
	* *Kamen Rider Ghost*: Orange
	* *Kamen Rider Ex-Aid*: Pink

- There are Rider Troops for each series, with the exception of *Build* and *Zi-O*.
	* *Kamen Rider Wizard*: Kamen Rider Mage
	* *Kamen Rider Gaim*: Kurokage Troopers
	* *Kamen Rider Drive*: Mass Production Model Mach
	* *Kamen Rider Ghost*: Kamen Rider Necroms
	* *Kamen Rider Ex-Aid*: Ride-Players

- Each series has a transformation belt that is utilized by at least two in-series Riders.
	* *Kamen Rider Wizard*: Mage's Belt (Orange Mage, Blue Mage, & Green Mage)
	* *Kamen Rider Gaim*: Sengoku Driver (Armored Riders) & Genesis Driver (Genesis Armored Riders)
	* *Kamen Rider Drive*: Mach Driver Honoh (Mach, Chaser, & Jun)
	* *Kamen Rider Ghost*: Ghost Driver (Ghost & Specter)
	* *Kamen Rider Ex-Aid*: Gamer Driver (Ex-Aid, Brave, Snipe, Lazer, Genm and later Para-DX) & Buggle Driver II (Poppy & Cronus)
	* *Kamen Rider Build*: Build Driver (Build & Cross-Z), Sclash Driver (Cross-Z Charge, Grease and Rogue), & Evol-Driver (Evol and MadRogue)
	* *Kamen Rider Zi-O*: Ziku-Driver (Zi-O, Geiz, Tsukuyomi), & Beyondriver (Woz)

- The series will usually take a secondary rider out of the action for various reasons and various lengths or even fights with the villains for multiple episodes.
	* *Kamen Rider Wizard*: Nitoh's Beast Driver is destroyed near the end of Wizard, though he temporarily joined the villains for one episode.
	* *Kamen Rider Gaim*: Kaito, who became antagonist near the end of the show, formed his own allies to fight against Kouta.
	* *Kamen Rider Drive*: Go feigns an alliance to the Roidmudes in order to get closer to them and retrieve Banno. By the end of the show, both Chase and Go are killed and incapacitated respectively in the final battle.
	* *Kamen Rider Ghost*: Makoto at one point is brainwashed by the Necrom Eyecon and in another point, his body is destroyed, leaving him out of the show for a couple of episodes.
	* *Kamen Rider Ex-Aid*: Hiiro Kagami is briefly incapacitated due to strain placed on his body by his Level 50 form. He later briefly allies himself with Masamune Dan in a bid to restore his girlfriend, though he returns to the heroes' side after a while.
	* *Kamen Rider Build*: Ryuga Banjo is possessed by Evolto for two episodes due to him having a piece of Evolto's DNA inside of him.
	* *Kamen Rider Zi-O*: Geiz Myokoin briefly sides with White Woz and became GeizRevive to kill Zi-O. After the ordeal with Another Zi-O, he returns to the 9 5DO. And in the altered timeline, he has no memory of Sougo whatsoever until he defeated Another Zi-O II.

- The leader of the main villain group is usually betrayed and sometimes, if not usually, killed by one of their subordinates.
	* *Kamen Rider Wizard*: Sou Fueki/Wiseman was killed by Sora Takigawa/Gremlin, who wanted the Philosopher's Stone.
	* *Kamen Rider Gaim*: Rosyuo was betrayed and killed by Redyue in search of the Golden Fruit.
	* *Kamen Rider Drive*: Heart and Medic betray Tenjuro Banno after his true plans were revealed.
	* *Kamen Rider Ghost*: Adel, wanting to take over the throne as the Gamma Emperor, first "assassinates" his father Adonis, framing his brother Alain for it. Later, he truly kills Adonis once and for all while Adonis is in his physical form. Later, Adel himself is betrayed by the Gammaizers, who absorbed the Great Eye for themselves.
	* *Kamen Rider Ex-Aid*: Parado severs ties with Kuroto Dan once the latter states the Bugsters are pawns for his schemes. He eventually murders Kuroto after his defeat by the main protagonists.
	* *Kamen Rider Build* has two cases:
		+ Soichi Isurugi (possessed by Evolto) betrays Gentoku Himuro and defects to Hokuto when the war for the Pandora Box broke out. In reality, he is also aligned with the Seito government, later furthering on his own agenda.
		+ A majority of Build's former enemies team-up with him to battle Evolto.
	* *Kamen Rider Zi-O*: A rather inverted case as Swartz disposes both Heure and Ora once his true plans are revealed.

- The plot of each season's summer movie usually involves an alternate world or timeline being shown in contrast with the present world or timeline, somewhat harking back to the early Heisei Phase 1 summer movies of Ryuki, 555, Blade and Kabuto, which feature alternate endings to the main series storyline.
	* *Kamen Rider Wizard*: *Kamen Rider Wizard in Magic Land* had Haruto and Koyomi end up in Magic Land.
	* *Kamen Rider Gaim*: In *Kamen Rider Gaim: Great Soccer Battle! Golden Fruits Cup!*, Kouta finds himself in an alternate dream world created by Lapis.
	* *Kamen Rider Drive*: In *Kamen Rider Drive: Surprise Future*, a dystopian future from the year 2035 is shown.
	* *Kamen Rider Ghost*: *Kamen Rider Ghost: The 100 Eyecons and Ghost's Fateful Moment* had Takeru and his friends end up in the Island of Eyecons.
	* *Kamen Rider Ex-Aid* In *Kamen Rider Ex-Aid: True Ending*, Emu has to travel to the Game World through Virtual Reality midway through the movie.
	* *Kamen Rider Build* breaks this trend, as *Kamen Rider Build: Be The One* takes place between episode 45 and 46, tied in to the events of the series proper.
	* *Kamen Rider Zi-O* had Sougo and company travel back to Sengoku period Japan to protect Clara Steinbelt, Krim's ancestor from the Quartzer, who are attempting to erase Kamen Rider Drive from history. The events in this movie are later revealed to be in a timeline separate from the events of the TV series.

- Each series includes a golden evil Kamen Rider:
	* *Kamen Rider Wizard*: Kamen Rider Sorcerer
	* *Kamen Rider Gaim*: Kamen Rider Mars
	* *Kamen Rider Drive*: Kamen Rider Gold Drive
	* *Kamen Rider Ghost*: Kamen Rider Extremer
	* *Kamen Rider Ex-Aid*: Gamedeus Cronus
	* *Kamen Rider Build*: Kamen Rider Evol
	* *Kamen Rider Zi-O*: Ohma Zi-O

- With the exception of Gaim's Kiwami Arms and Ex-Aid's Muteki Gamer, all protagonist Riders lose their final form at the end of the series, though most would later regain said form at some point after their season's end.
	* *Kamen Rider Wizard*: Haruto gave his Infinity Ring to his A.R. counterpart.
		+ However, he regains said form after obtaining another Infinity Ring, that being from his Bujin counterpart, during the events of *Kamen Rider × Kamen Rider Gaim & Wizard: The Fateful Sengoku Movie Battle*.
	* *Kamen Rider Drive*: Mr. Belt locked himself and all Drive equipment underground.
	* *Kamen Rider Ghost*: The Mugen Eyecon faded away after Takeru used it to defeat the giant Great Eyezer.
		+ However, Takeru would somehow regain Mugen Damashii by the events of *Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Rider*.
	* *Kamen Rider Build:* The Genius Bottle is drained of its essence during the final battle against Evolto, prompting Sento to resort into using RabbitRabbit, RabbitTank Sparkling, RabbitTank, and finally, RabbitDragon forms.
		+ However, *Build NEW WORLD: Kamen Rider Cross-Z* shows that Sento managed to recreate a new Genius Fullbottle.
	* *Kamen Rider Zi-O:* Following Sougo's transformation into Ohma Zi-O, he reset the timeline, consequently erasing his equipment he achieved as well.
		+ However, Sougo would somehow regain GrandZi-O during the events of *Kamen Rider: Reiwa The First Generation* and *Kamen Rider Zi-O NEXT TIME: Geiz, Majesty*.

- With the exception of *Gaim*, each series has at least one Kamen Rider with a father or father-like figure Kamen Rider.
	* *Kamen Rider Wizard*: Sou Fueki is Koyomi Fueki's father. Both are Kamen Rider Wiseman (although Koyomi become Kamen Rider after her father).
	* *Kamen Rider Drive*:
		+ Tenjuro Banno (Gold Drive) is father of Go Shijima (Kamen Rider Mach). Although Gold Drive's status as Kamen Rider is debatable.
		+ Shinnosuke Tomari/Kamen Rider Drive later has son, named Eiji, who also become Kamen Rider Drive in the future.
	* *Kamen Rider Ghost*:
		+ Daigo Fukami (Kamen Rider Zero Specter) is adoptive father of Makoto and Kanon (Kamen Rider Specter and Kanon Specter respectively).
		+ Takeru Tenkuji (Kamen Rider Ghost) later has son, named Ayumu, who become Kamen Rider Ghost in the future. His father, Ryu Tenkuji, is also Kamen Rider Zero Ghost in the novel.
	* *Kamen Rider Ex-Aid*:
		+ Masamune Dan (Kamen Rider Cronus) is father of Kuroto Dan (Kamen Rider Genm).
		+ Emu Hojo (Kamen Rider Ex-Aid) has father, named Kiyonaga, who become Kamen Rider Genm in the novel.
	* *Kamen Rider Build*: Shinobu Katsuragi is father of Takumi Katsuragi and Sento Kiryu. They all are Kamen Rider Build.
	* *Kamen Rider Zi-O*: Tamotsu Douan (Another Quiz) is father of Mondo Douan (Kamen Rider Quiz).

- The main Rider usually uses a disproportionately high number of collectible transformation devices as compared to the other Riders.
	* *Kamen Rider Gaim*: Gaim has altogether used a total of 18 Lockseeds (counting borrowed, stageshow-exclusive and Legend Rider), as compared to the other Riders who at most, have not used more than 10 different Lockseeds.
	* *Kamen Rider Drive*: Drive possesses a total of 31 Shift Cars in his arsenal (counting Tire Exchange Shift Cars which were not used in battle), as compared to the Signal Bikes' small number of 7.
	* *Kamen Rider Ghost*: Out of the 15 heroic Ghost Eyecons, Ghost has 10, while Specter has 3 and Necrom only has 2.
	* *Kamen Rider Ex-Aid*: In a slightly less extreme case, Ex-Aid makes use of a total of 15 Gashats across all episodes, movies, and specials, with Brave in second place at 8, and Snipe in third at 6 (7 counting his appearance as Cronus).
	* *Kamen Rider Build*: There are a total of 60 regular Fullbottles that Build can potentially use for his Best Match forms, plus 3 other unique Bottles for his power-up forms, while all other Riders and Rider-like warriors have only used standalone Fullbottles or variants of those (Sclashjellies, Gears, Evolbottles etc.)
	* *Kamen Rider Zi-O*: Of the Ridewatches based on the 19 main Heisei Riders, although both Zi-O and Geiz could potentially use any of them to access their corresponding Rider Armors, 16 Rider Armors have been designed for Zi-O, whilst Geiz only has 6 forms designed for him.

- Each season usually has the third main Rider originally start off as good during or before the start of the series, then become evil for a period of time before finally redeeming themselves and going on the side of good again. Their Rider forms usually have either purple or green accents (or both in Ryugen's case).
	* *Kamen Rider Gaim*: Mitsuzane Kureshima, originally a friend of Kouta, later joins and eventually takes over Yggdrasill, betraying everyone around him. At the end of the series, he redeems himself for the sins he had committed.
	* *Kamen Rider Drive*: Chase was originally Protodrive, the warrior who fought the Roidmudes during the Global Freeze, before being brainwashed into becoming Mashin Chaser. Later, he regains his memories and becomes Kamen Rider Chaser.
	* *Kamen Rider Ghost*: It is not known if Alain was originally good at first, but he grew to believe that his world was perfect and that the human world was flawed. Later, after the death of his father Adonis, Alain finally accepts that his world is not perfect, and joins the side of good as Kamen Rider Necrom.
	* *Kamen Rider Ex-Aid*: Taiga Hanaya was originally a kind doctor who was part of CR. However, the effects of the Proto Gashats had affected his mind and body, turning him into a somewhat anti-heroic Rider, though he later comes to respect the other Kamen Riders over the course of their fight against the Bugsters. This also applies to Kuroto Dan, who is first introduced as a villain for the first half of the season, until he joins with the heroes when his father took over Kamen Rider Chronicle.
	* *Kamen Rider Build*: Kazumi Sawatari started out as hostile towards the protagonists as he was the representative Rider whose government opposing Touto. He joins with them following the deaths of his three comrades. This also applies to Gentoku Himuro, who started out as one of the members of Faust and subsequently the Kamen Rider of Seito, he joins with the heroes following the death of his father.
	* *Kamen Rider Zi-O* is a unique and inverted case as White Woz (the first Kamen Rider Woz) was more (secretly) villainous whereas Black Woz (the second Kamen Rider Woz) was more of an ally to the heroes at the time of becoming a Rider.

- The main villains usually possess an omnipotent object or entity of great power, which can possibly inflict mass destruction on the world.
	* *Kamen Rider Gaim*: The Forbidden Fruit contains the power to paint the entire world in one's image i.e. destroying the current world and creating a new one.
	* *Kamen Rider Drive*: The Sigma Circular, created by Tenjuro Banno, caused the second Global Freeze which temporally froze the entire world and almost digitized all the humans into data.
	* *Kamen Rider Ghost*: The Gammaizers are the deities which watch over the Gamma World. They possess enough power to eliminate any form of obstacles in their way and become stronger every time they are defeated. There is also the mighty Great Eye.
	* *Kamen Rider Ex-Aid*: Kamen Rider Chronicle, a game project originally created by Kuroto Dan, is now being used as a ploy by the Bugsters to slowly annihilate humanity. After Masamune Dan regains control of Genm Corp., he uses Kamen Rider Chronicle for his own agenda, even using Gamedeus to his advantage.
	* *Kamen Rider Build*: The Pandora Box is an artifact from Mars that served as the catalyst to the Sky Wall Disaster, dividing Japan into three regions - Touto, Hokuto, and Seito. With Japan trisected, each of the regions set out in a war for the control of the box. Later, Evolto takes control of the Pandora Box with the goal of destroying Earth, much like he did with Mars.
	* *Kamen Rider Zi-O*: Although not necessarily a villain himself, Ohma Zi-O possesses the power to destroy and re-create the timeline in his image.

- A certain transformation device from each season has either a prototype or a mass-produced version.
	* *Kamen Rider Gaim*: The Sengoku Drivers are mass-produced for use by the Kurokage Troopers. Previously, there were six prototype yellow-strapped Sengoku Drivers.
	* *Kamen Rider Drive*: The Mach Driver Honoh was mass-produced for use by the production model of Kamen Rider Mach.
	* *Kamen Rider Ghost*: The Mega Ulorder has a prototype which is used by Igor. This prototype is later mass-produced and used by Kamen Rider Dark Necrom Red, B and Y.
	* *Kamen Rider Ex-Aid*: There are prototype versions of the 10 regular Rider Gashats. A mass-produced version of the Kamen Rider Chronicle Gashat is later distributed to the public to transform into Ride-Players.
	* *Kamen Rider Build*: The Build Driver is actually a weaker version of the Evol-Driver.
	* *Kamen Rider Zi-O*: The Miraidrivers are modified variants of the Ziku-Driver.

- The main villains use a unique way of moving from one place to another in an instant.
	* *Kamen Rider Gaim*: The Inves can open up Cracks to move between Earth and the Helheim Forest.
	* *Kamen Rider Drive*: Roidmude cores can travel through computer networks.
	* *Kamen Rider Ghost*: The Gamma can create portals to traverse between the human world and the Gamma world.
	* *Kamen Rider Ex-Aid*: The Bugsters are shown to be able to traverse via the digital world.
	* *Kamen Rider Build*: Evolto, after absorbing the black-colored Lost Panel with the 10 Lost Bottles, can warp to other worlds via wormholes.
	* *Kamen Rider Zi-O*: Swartz, as Another Decade, can teleport himself along with his enemies to the Another Worlds via the Aurora Curtains.

- With the exception of *Zi-O*, each season has a spring movie which focuses more heavily on the Kamen Riders rather than other tokusatsu seasons, as compared to the first two Super Hero Taisen films. Incidentally, Kamen Rider 1 plays a significant role in each of these films.
	* *Kamen Rider Gaim*: In *Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai*, Rider 1 leads the Showa Riders, wanting to battle the Heisei Riders.
	* *Kamen Rider Drive*: In *Super Hero Taisen GP: Kamen Rider 3*, history is changed because of Rider 1 and 2's defeat at the hands of Rider 3.
	* *Kamen Rider Ghost*: Kamen Rider 1 is the main focus character in the *Kamen Rider 1* film.
	* *Kamen Rider Ex-Aid* breaks this trend by having the spring movie return to a Taisen film in the form of *Kamen Rider × Super Sentai: Chou Super Hero Taisen*. Interestingly, Kamen Rider 1 does not appear in this movie.
	* While *Kamen Rider Build* has no designated spring movie, this is replaced by a movie for the Amazon Prime-exclusive web series *Kamen Rider Amazons*.

- Each season has a spinoff side story focusing on one of the main characters apart from the primary Rider.
	* *Kamen Rider Gaim*: *Kamen Rider Gaim Gaiden* had side stories featuring Baron, Zangetsu, Knuckle, Duke, Gridon, and Bravo.
	* *Kamen Rider Drive*: The *Drive Saga* series initially had one side story focusing on Chaser, but after its initial popularity and success, two more Drive Sagas focusing on Mach and Heart were released, with another focusing on Brain many years later.
	* *Kamen Rider Ghost*: *The Legend of Hero Alain* focuses on Alain, and *Ghost RE:BIRTH: Kamen Rider Specter* on Makoto.
	* *Kamen Rider Ex-Aid*: Ex-Aid manages to provide specials/movies for almost every Rider, including:
		+ *Kamen Rider Snipe: Episode ZERO*
		+ *Kamen Rider Ex-Aid "Tricks": Kamen Rider Genm*
		+ *Kamen Rider Brave: ~Let's Survive! Revival of the Beast Rider Squad!~*
		+ *Kamen Rider Ex-Aid "Tricks": Kamen Rider Lazer*
		+ *Kamen Rider Ex-Aid "Tricks": Kamen Rider Para-DX*
		+ *Kamen Rider Ex-Aid Trilogy: Another Ending*
			- *Kamen Rider Brave & Snipe*
			- *Kamen Rider Para-DX with Poppy*
			- *Kamen Rider Genm vs. Lazer*
	* *Kamen Rider Build*: *ROGUE* focuses on the backstory of Gentoku Himuro, while *Build NEW WORLD: Kamen Rider Cross-Z* and *Build NEW WORLD: Kamen Rider Grease* focuses on Ryuga Banjo and Kazumi Sawatari respectively.
	* *Kamen Rider Zi-O*: *Kamen Rider Zi-O Spin-off* focuses on both Kamen Rider Shinobi & Kamen Rider Ryuki respectively, and *Kamen Rider Zi-O NEXT TIME: Geiz, Majesty* focuses on Geiz Myokoin.

- The secondary Riders' super/final forms are actually equivalent to the protagonist Riders' Upgrade Forms.
	* *Kamen Rider Gaim*: Baron Lemon Energy Arms uses the same kind of Energy Lockseed as Gaim Jimber Lemon Arms.
	* *Kamen Rider Drive*: Deadheat Mach shares Shift Deadheat with Drive Type Dead Heat.
	* *Kamen Rider Ghost*: Deep Specter's design and weapon are nearly identical to Ghost Toucon Boost Damashii.
	* *Kamen Rider Ex-Aid*: The Gashat Gear Dual β shared by Brave and Snipe has its "double Gashat" concept inspired by Ex-Aid's Mighty Brothers XX Gashat.
	* *Kamen Rider Build*: Cross-Z Magma's evolution from Cross-Z's default form seems to be a nod to Build's RabbitTank Sparkling, which itself is an evolution from Build's default RabbitTank Form. Later, Grease Blizzard would also utilize the same concept, with both Cross-Z Magma and Grease Blizzard using similar knuckle-like devices to transform.
	* *Kamen Rider Zi-O*: GeizRevive was specially designed to be able to counter Zi-O II, as part of White Woz's plans to establish his own version of Oma's Day.

- The primary Riders' final form no longer has its own designated weapon. Instead, it uses the weapon used by the upgrade/super form to generate more powerful attacks.
	* *Kamen Rider Gaim*: Gaim Kiwami Arms uses the Hinawadaidai-DJ-Ju, which is Kachidoki Arms' default weapon. While Gaim Kachidoki Arms uses the Kachidoki Lockseed in the Hinawadaidai-DJ-Ju to perform a **Kachidoki Charge**, Gaim Kiwami Arms instead uses normal Lockseeds to perform a **Fruits Basket Charge**.
	* *Kamen Rider Drive*: Drive Type Tridoron uses the Trailer-Hou, normally used by Drive Type Formula. While Drive Type Formula inserts Shift Formula into the Shift Landing Slot to perform the **Trailer Impact**, Drive Type Tridoron instead inserts a regular form Type Change Shift Car into the Shift Landing Slot to perform the **Trailer Big Impact**.
	* *Kamen Rider Ghost*: Ghost Mugen Damashii (final form), as well Grateful Damashii (super form), reuses the Sunglasseslasher from Toucon Boost Damashii.
	* *Kamen Rider Ex-Aid*: Ex-Aid Maximum Gamer Level 99 (super form) and Muteki Gamer (final form) reuse the Gashacon Key Slasher from his Double Action Gamer Level XX form.
	* *Kamen Rider Build*: Build Genius Form reuses the Fullbottle Buster from Build's RabbitRabbit and TankTank Forms.
	* *Kamen Rider Zi-O*: Both Zi-OTrinity and GrandZi-O reuse the Saikyo Girade from Zi-O II.

- Legend Rider collectible items from Gaim onwards allow the users to transform into special forms that are themed after those legend Riders, unlike previous Legend Rider collectible items, which merely summoned the corresponding Riders.
	* The Legend Rider Fullbottles from *Kamen Rider Build* allow Build to transform into the respective Legend Rider itself, much like Decade's main ability of transforming into past Riders.
	* As the 20th and final Heisei Kamen Rider season, the Legend Rider collectible items become the main gimmick of *Kamen Rider Zi-O*.

- With the exception of Drive and Zi-O, all series have at least one Rider having a music-related power/weapon:
	* *Kamen Rider Gaim*: Gaim's Hinawadaidai-DJ-Ju.
	* *Kamen Rider Ghost*: Beethoven Damashii.
	* *Kamen Rider Ex-Aid*: DoReMiFa Beat & Beat Gamer.
	* *Kamen Rider Build*: Beat Closer.

- There is at least one ninja-based Rider or Rider form:
	* *Kamen Rider Gaim*: Ichigo Arms.
	* *Kamen Rider Drive*: Shift Midnight Shadow.
	* *Kamen Rider Ghost*: Goemon Damashii.
	* *Kamen Rider Ex-Aid*: Kamen Rider Fuma & Hurricane Ninja.
	* *Kamen Rider Build*: Ninjya Halfbody.
	* *Kamen Rider Zi-O*: Kamen Rider Shinobi.

- Though the trend of Net Movies has stopped since Gaim, each season's summer movie now has tie-in episodes which now directly relate to the plot of the summer movie. This was originally preceded by *Kamen Rider Blade: New Generation*, a tie-in miniseries to *Kamen Rider Blade: Missing Ace*. *Kamen Rider Ex-Aid* breaks this trend.
	* *Kamen Rider Gaim*: *Baron's Soccer Showdown Summer Camp!*
	* *Kamen Rider Drive*: *Kamen Rider Drive: Movie Roadshow Commemoration! 1 Minute Stories*
	* *Kamen Rider Ghost*: *Kamen Rider Ghost: Commemoration! Short Stories*

- All series feature Kamen Riders with purple/violet color dominant in their main form. They're usually third or fourth Rider to appear in series.
	* *Kamen Rider Gaim*: Kamen Rider Ryugen is the fourth Rider to appear in series, after Gaim, Zangetsu and Baron.
	* *Kamen Rider Drive*: Kamen Rider Chaser is the fourth Rider to appear in series, after Protodrive, Drive and Mach.
	* *Kamen Rider Ghost*: Kamen Rider Zero Specter, although he appears only in the Movie.
	* *Kamen Rider Ex-Aid*: Kamen Rider Genm is "actually" the third Rider to appear in series, after Ex-Aid and Brave.
	* *Kamen Rider Build*: Kamen Rider Rogue is the fourth Rider after Build, Cross-Z, and Grease.
	* *Kamen Rider Zi-O*: Kamen Rider Shinobi is the fourth Rider after Zi-O, Geiz, and Woz.

- With the exception of *Ex-Aid*, each series has sibling Kamen Riders.
	* *Kamen Rider Gaim*: Kureshima sibling
		+ Takatora Kureshima/Zangetsu & Mitsuzane Kureshima/Ryugen
	* *Kamen Rider Drive*: Shijima sibling
		+ Kiriko Shijima/Drive (intended user) & Go Shijima/Mach.
	* *Kamen Rider Ghost*: Gamma Royal sibling & Fukami sibling
		+ Argos/Dark Ghost/Extremer, Alia/Dark Necrom P & Alain/Necrom.
		+ Makoto Fukami/Specter & Kanon Fukami/Kanon Specter
	* *Kamen Rider Build*: Blood tribe sibling
		+ Killbus & Evolto/Evol
	* *Kamen Rider Zi-O*: Time Jacker royal sibling
		+ Swartz (Another Decade) & Tsukuyomi

- There is at least 1 sentient Rider Machine in each series, with the exception of Build's Machine Builder & Zi-O's Ridestriker:
	* *Kamen Rider Drive*: As a part of Drive system, Tridoron can be remotely controlled by Mr. Belt.
	* *Kamen Rider Ghost*: Machine Ghostriker/Iguana Ghostriker, as well as Machine Hoodie which is the manifestation of the Houdini Damashii.
	* *Kamen Rider Ex-Aid*: Lazer Bike Gamer Level 2 is actually a Kamen Rider who has a bike form.

- With the exception of Zi-O, there is at least 1 Rider who can combine with his Rider Machine to obtain a form:
	* *Kamen Rider Drive*: Drive can combine with Tridoron to become Drive Type Tridoron.
	* *Kamen Rider Ghost*: Specter can combine with Machine Hoodie to become Specter Houdini Damashii.
	* *Kamen Rider Ex-Aid*: Genm can combine with his Sports Gamer to become Genm Sports Action Gamer Level 3. This is later inherited by Ex-Aid after claiming the Shakariki Sports Gashat. Ex-Aid can combine with Bike Gamer to became Ex-Aid Bike Action Gamer Level 0.
	* *Kamen Rider Build*: Build can combine with Machine Builder by using the Bike Fullbottle with the Same Fullbottle to become Build SameBike Form

- The Blu-ray releases of each season have a mini-series tied in, often as an additional side story within the series' narrative.
	* *Kamen Rider Drive*: *Secret Mission Type TOKUJO*
	* *Kamen Rider Ghost*: *The Legend of Hero Alain*
	* *Kamen Rider Ex-Aid*: *Kamen Rider Snipe: Episode ZERO*
	* *Kamen Rider Build*: *ROGUE*
	* Although *Kamen Rider Zi-O* doesn't have one in its Blu-Ray release, it does have a miniseries in the form of *Kamen Rider Zi-O Spin-off*, released for Toei Tokusatsu Fan Club.

- Each season features initial conflict or some form of a rivalry between the series' secondary and tertiary rider before becoming comrades.
	* *Kamen Rider Drive*: Go Shijima (Kamen Rider Mach) previously had immense hatred for the Roidmudes, even Chase (Kamen Rider Chaser), despite the android's return to his original heroic personality. This hostility ended after Chase sacrificed himself at an attempt to stop Gold Drive, with Go finally acknowledging Chase as a comrade and avenged his death as Chaser Mach.
	* *Kamen Rider Ghost*: Makoto Fukami (Kamen Rider Specter) was previously friends with Alain (Kamen Rider Necrom) in the Gamma World. After Makoto joined the Daitenku Temple to fight the Gamma, Alain took it himself to become Kamen Rider Necrom and fought against his former friend as a means to forcibly bring him back to the Gamma World. Their clashing ended after Alain's banishment and he eventually rekindled his friendship with Makoto.
	* *Kamen Rider Ex-Aid*: Hiiro Kagami (Kamen Rider Brave) initially had a grudge against Taiga Hanaya (Kamen Rider Snipe) being the one responsible for the death of his girlfriend. After Taiga was badly injured by Graphite. Hiiro decide to save him, forfeiting the chance to save Saki, rekindling their comradeship and ending their grudge to one another.
	* *Kamen Rider Build*: Ryuga Banjo (Kamen Rider Cross-Z) and Kazumi Sawatari (Kamen Rider Grease) didn't get along at first and started off as enemies during the Touto-Hokuto war. After Kazumi joined Team Build to fight against Seito, the two soon became friends. Kazumi is the only rider to call Ryuga Banjo by his first name while everyone else calls him by his last name.
	* *Kamen Rider Zi-O*: Geiz Myokoin (Kamen Rider Geiz) and Black Woz (Kamen Rider Woz) were previously "old friends" in the Resistance before the latter betrayed them and joined Ohma Zi-O. Both have an uneasy relationship because of this, but would later put aside their differences and reconcile after some instigation from Sougo Tokiwa.

- Except Zi-O, each season's villain group has a monster who chooses to befriend humans rather than attack them. With the exception of the Gazai Gamma, the monster eventually gets killed by the main villain groups for their perceived betrayal.
	* *Kamen Rider Drive*: Roidmude 072
	* *Kamen Rider Ghost*: Gazai Gamma
	* *Kamen Rider Ex-Aid*: Burgermon Bugster
	* *Kamen Rider Build*: The Hokuto Sanbagarasu are a special case, both are a trio of Hard Smash (and later Hazard Smash) with the purpose of fighting alongside with their boss.

- Each season's spring movie has a web-exclusive miniseries accompanying their release.
	* *Kamen Rider Drive*: *D-Video Special: Kamen Rider 4*
	* *Kamen Rider Ghost*: *Kamen Rider Ghost: Legendary! Riders' Souls!*
	* *Kamen Rider Ex-Aid*: *Kamen Sentai Gorider*

- Most of the major villains at the start of the series would turn good at the end of it, and the last boss is usually another person (Tenjuro Banno, Gammaizers, and Masamune Dan) appearing much later. Evolto (to an extent) and Swartz broke the trend by being around the show's first quarter to the very end.

- With the exception of Ghost, all series introduced an evil Rider-like character with a mysterious identity at the start of the series.
	* *Kamen Rider Drive*: Mashin Chaser
	* *Kamen Rider Ex-Aid*: Black Ex-Aid
	* *Kamen Rider Build*: Night Rogue and Blood Stalk
	* *Kamen Rider Zi-O*: Ohma Zi-O

- Each season has Kamen Riders with same name as the user's civilian identity.
	* *Kamen Rider Drive*: Jun Honganji/Kamen Rider Jun, Heart/Kamen Rider Heart, & Brain/Kamen Rider Brain
	* *Kamen Rider Ghost*: Kanon Fukami/Kamen Rider Kanon Specter
	* *Kamen Rider Ex-Aid*: Poppy Pipopapo/Kamen Rider Poppy
	* *Kamen Rider Build*: Killbus/Kamen Rider Killbus
	* *Kamen Rider Zi-O*: Geiz Myokoin/Kamen Rider Geiz, Woz/Kamen Rider Woz, & Tsukuyomi/Kamen Rider Tsukuyomi

- The opening sequence of each season would have a short clip which would be reused directly in the season's later episodes, or have some of its elements used to make similar scenes in the season's endgame arc. This has led to the opening sequence somewhat "foreshadowing" certain events in each season.
	* *Kamen Rider Drive*: The opening features a short scene with Tridoron driving through several giant teeth-like structures emerging from the ground. This scene would be reused in episode 45 as Drive, Mach, and Chaser race towards the Sigma Circular's location, with the giant structures being generated by the Sigma Circular itself to deter the three Riders' pursuit.
	* *Kamen Rider Ghost*: The opening features a scene with Takeru flying in the sky together with the Ore, Musashi, Edison, Robin Hood, and Newton Parka Ghosts, while Akari and Onari look up at him from the ground. A similar scene occurs right after Takeru comes back to life in episode 49, with Takeru flying together with the 15 heroic Damashii, with all of his friends watching him from the ground.
	* *Kamen Rider Ex-Aid*: The opening features a short scene with Ex-Aid, Brave, Snipe, and Lazer standing together at night. This scene is first used in episode 1 right before the show's logo appears, and is used again in the finale after the four Riders transform together in the final battle against Cronus.
	* *Kamen Rider Build*: The opening features a snippet showing giant, physical manifestations of mathematical equations colliding with the Sky Wall and demolishing it. This snippet is reused in the finale during the sequence where the two worlds are merged to create the new world.
	* *Kamen Rider Zi-O*: The opening features a short scene set in 2068, where the rusted surface of the Legend Rider statues begin to break and flake off, revealing the original statues in their pristine condition. Starting from Grand Zi-O's debut in episode 40, a similar sequence would be featured in Grand Zi-O's transformation, with the addition of a Zi-O statue alongside the previous 19 Heisei Rider statues.
		+ There is also another short snippet featuring Tsukuyomi together with the three Time Jackers. While this scene is not directly reused, it eventually foreshadows Tsukuyomi's own heritage and abilities as a Time Jacker.

- With exception of Ghost and Ex-Aid, the final villain of each season is one of the major villains who had been around since the very beginning.
	* *Kamen Rider Drive*: Heart
	* *Kamen Rider Build*: Evolto
	* *Kamen Rider Zi-O*: Swartz

- With the exception of Zi-O, the main rider has a Super Form that usually causes the user to go berserk before having something that would regain the rider's control.
	* *Kamen Rider Build*: Hazard Form (regained control via FullFull RabbitTank Bottle)

- The main rider has an extra final form appearing in the series finale.
	* *Kamen Rider Build*: RabbitDragon Form
	* *Kamen Rider Zi-O*: Ohma Zi-O
		+ Although Ohma Zi-O is Zi-O's true final form, it's still an extra final form since GrandZi-O is considered as a final form.

## Kamen Rider in the Heisei Phase 2 era

The crossover between a Kamen Riders from a different series was all started from the *Kamen Rider Den-O & Kiva: Climax Cop* in Phase 1, as a starter up for the next Rider crossover within Phase 2, starting from *Movie War* series.

Advertisements throughout the months of May, June, and July 2009 built up to the debut of *Kamen Rider W* who was introduced as the eleventh addition of the Heisei Era, first appearing at the 10th Anniversary Project MASKED RIDER LIVE & SHOW event, and was featured in *Kamen Rider Decade: All Riders vs. Dai-Shocker*. The title characters star as detectives investigating crime waves about kaijin known as Dopants in the fictional city of Futo. Like much of the previous entries of the Heisei Era, the titular Rider, Kamen Rider Double, can transform into multiple forms, using devices shaped like USB hard drives called Gaia Memories. The Dopants that they fight are really people that use unrefined Gaia Memories for their own purposes. Double is also the first Kamen Rider to transform from two people at once. This series is also the first instance where the show airs on the same day it's predecessor (in this case, Decade) airs it's finale. The series premiered on September 6, 2009. Continuing into 2010 with *Kamen Rider × Kamen Rider W & Decade: Movie War 2010*, *W* ran for a full year from September 2009 to September 2010, instead of January to January. Also in 2010 were the second, third, and fourth films of the Cho-Den-O Series, collectively known as *Kamen Rider × Kamen Rider × Kamen Rider: Cho-Den-O Trilogy*. Along with Den-O and Kabuto, it became one of the most successful Heisei Kamen Rider series.

In late 2010, *Kamen Rider OOO* was introduced as the twelfth addition of the Heisei Era Kamen Rider Series. The title character is a world traveler that is pulled into a fight with kaijin called the Greeed that was resurrected from a 800-year sleep to find themselves incomplete by such a Greeed, reduced to the status of a forearm, who gives him the means to transform into Kamen Rider OOO. Like Kamen Riders BLACK RX to Agito, and Den-O to Double, Kamen Rider OOO can change forms, but unlike the others, OOO can transform using three Core Medals, special coin-based artifacts based on animals that make up a Greeed's ability to stay alive without falling apart. There are nine Core Medals for each set, three each designated for Head, Arms, or Legs. As so far, OOO has the most transformations in Kamen Rider history, having able to use a possible 126 different combinations of Core Medals.

The year 2011 celebrated the 40th anniversary of the franchise. The festivities included the Kamen Rider Girls idol group, the film *OOO, Den-O, All Riders: Let's Go Kamen Rider*, released on April 1, 2011, and OOO's successor *Kamen Rider Fourze*, which references the previous heroes in its characters' names and within the plot. *OOO, Den-O, All Riders: Let's Go Kamen Rider* was the first starter up of the Taisen movie series, which was included Super Sentai's Akaranger, Other heroes like Zuban, original Kikaiders and original Inazuman, resulting a development of the first Super Hero Taisen crossover film titled *Kamen Rider × Super Sentai: Super Hero Taisen*, which was released in 2012, featuring the main heroes from all *Kamen Rider* and *Super Sentai* series produced until then, then becomes expanded with the other heroes like Metal Heroes (particularly Space Sheriffs) and the other heroes like new Inazuman from *Movie War Ultimatum*, sans in Gaim and Drive's own spring movies, which focused on all Kamen Riders with less Super Sentai team that focused on the sophomore and the current ones.

In late 2012, *Kamen Rider Wizard* was introduced as the fourteenth addition of the Heisei Era Kamen Rider Series. As the series ran for 53 episodes, it was marked as the longest run in the Heisei Era, beating *Agito* with two episodes. Chisato Akita joined the Kamen Rider Girls that year, representing Wizard. As the series ran for 53 episodes, it was marked as the longest run in the Heisei Era, beating *Agito* with two episodes. The final two episodes of Wizard featured the first 14 Heisei Riders and introduced Kamen Rider Gaim as the 15th.

In late 2013, *Kamen Rider Gaim* was introduced as the fifteenth addition of the Heisei Era Kamen Rider Series. Unlike the recent series, it started off with multiple Riders appearing and it did not follow the two-part episode format. Tomomi Jiena Sumi joined the Kamen Rider Girls group that year, and would later appear as Masako Suzuka seven years after the end of *Gaim*. Gaim would not meet his successor until the events of *Kamen Rider × Kamen Rider Drive & Gaim: Movie War Full Throttle*.

In late 2014, *Kamen Rider Drive* was introduced as the sixteenth addition of the Heisei Era Kamen Rider Series. Unlike most of the Kamen Riders, the title character drives a car instead of a bike. The Kamen Rider Girls did not have a new member representing Drive. Drive would not meet his successor until the events of the final episode and *Kamen Rider × Kamen Rider Ghost & Drive: Super Movie Wars Genesis*.

In late 2015, *Kamen Rider Ghost* was introduced as the seventeenth addition of the Heisei Era Kamen Rider Series. Ayako Kuroda had joined Kamen Rider Girls in the year *Ghost* began airing. Ghost would act as a bridge between *Drive* and *Kamen Rider Ex-Aid* where they'd meet in *Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Riders*. Ghost himself would later continuously appear in all future installments of *Heisei Generations*.

In late 2016, *Kamen Rider Ex-Aid* was introduced as the eighteenth addition of the Heisei Era Kamen Rider Series. Towards the end of its summer film *Kamen Rider Ex-Aid: True Ending*, it introduced a cliffhanger ending featuring Kamen Rider Build himself, which chronologically led into their Movie War film *Kamen Rider Heisei Generations Final: Build & Ex-Aid with Legend Riders*.

In late 2017, *Kamen Rider Build* was introduced as the nineteenth addition of the Heisei Era Kamen Rider Series. Unlike the previous installments, *Build* took place in a parallel world. The characters from this universe would later interact with characters from the prime universe in *Heisei Generations FINAL*. Both worlds would merge by the end of Build's season, leading up to the events of *Kamen Rider Heisei Generations Forever* and Build's own *NEW WORLD* series of V-Cinema films.

In late 2018, *Kamen Rider Zi-O* was introduced as the twentieth and final addition of the Heisei Era Kamen Rider Series. The series serves an anniversary season like *Decade*, where it commemorates its predecessors by using collectible devices based on previous Riders. The summer film, *Kamen Rider Zi-O: Over Quartzer* would set-up the Reiwa Series by introducing *Kamen Rider Zero-One* and crossing over with him in *Kamen Rider: Reiwa The First Generation*.

## Number Theory?

 File:KR Number Theme.png
A fan theory about Phase 2 is that each series seems to follow an increasing numbered theme, although this gradually became less obvious with each season:

* *Kamen Rider Double* : A Kamen Rider formed from **TWO** people using a Driver with **TWO** slots.
* *Kamen Rider OOO*: A Kamen Rider who uses **THREE** Medals to transform.
* *Kamen Rider Fourze*: A Kamen Rider with weapons on his **FOUR** limbs, using a Driver with **FOUR** slots. Also, the forty anniversary of the series, with the word **FOUR**ZE in its name.
* *Kamen Rider Wizard*: A Kamen Rider who uses magic via **FIVE**-fingered hand-shaped scanners.
* *Kamen Rider Gaim*: Lockseeds are shaped like number **6**.
* *Kamen Rider Drive*: The shape of part of the Katagana ve (ブ, *bu*?) of the title logo shaped like the number **SEVEN**. Also Shift Cars when in their lever modes are shaped like the number **7**
* *Kamen Rider Ghost*: The Infinity symbol ∞, which looks like a horizontal number **8**, appears in many ways in the series (Sunglasseslasher/Deep Slasher's slots, Mugen Damashii, etc.)

Takahito Omori later claimed that Ex-Aid's number was **10**, which conflicted with the theory.. In 2019, Shin-ichiro Shirakura officially denied and put an end to the theory.
