Kamen Rider Series/Heisei Series Phase 2

, 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. The second phase lasted for a total of ten seasons up until the end of the Heisei era in Japan in 2019, ending with Kamen Rider Zi-O, which finished its run in August 2019.
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==
==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 , 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?==
A fan theory about Phase 2 is that each series seems to follow a increasing number theme, which became gradually less obvious: 
*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 FOURZE 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 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 throughout 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 as it skipped a numberhttp://www.toei.co.jp/tv/ex-aid/story/1208131_2606.html. In 2019, Shin-ichiro Shirakura officially denied and put an end to the theory.I’m sure it’s not true. - Shin-ichiro Shirakura's tweet
