"Ryuga_Banjo".jpg/revision/latest?cb=20180527114007 is an ex-fighter who transforms into .
==History==
===Background===
Ryuga Banjo is the son of Yuri Banjo and her unnamed husband. In 1994, a Martian space probe returned to Japan, carrying an alien specimen, revealed to be a portion of Evolto. The specimen attached itself to Yuri, a security guard stationed with her husband. The specimen integrated itself with Banjo during his fetal stage, causing Yuri to lose consciousness on duty. About a month later, Ryuga Banjo was born in Yokohama, appearing healthy despite a two-month gestation period, weighing 3.2 kg.
However, all memories and powers that the specimen possessed were lost, rendering Banjo as human. Due to the peculiar nature of his birth, Banjo was examined at a university hospital before being transferred to Namba Heavy Industries. He was involved in periodic examinations under Shinobu Katsuragi's supervision, discovering that his genes are of extraterrestrial origin. When Banjo was 13, his parents were killed by Evolto, though Banjo himself remembers nothing of their deaths.
As an adult, Banjo became a professional fighter and was engaged to Kasumi Ogura. However, he earned a lifelong ban for participating in a fixed match, implied to pay for Kasumi's medical expenses. While searching for a new job, Kasumi directed him to Takumi Katsuragi, a scientist in need for a lab assistant. When Banjo entered Katsuragi's apartment, he found the scientist's corpse inside and was later arrested by the police for his supposed murder. He was sentenced for ten years in the Touto Correctional Facility, where he was abducted by Masahiro Nabeshima and taken to Faust to underwent experimentation.
===Waking The Dragon===
After escaping from his captivity, Banjo reached the city and fended off the Touto Guardians. After encountering Sento Kiryu at the power plant, Banjo is intercepted by the Strong Smash and is saved by Sento after he transformed into Kamen Rider Build. Believing in his innocence that he didn't kill Katsuragi, Banjo was brought to the Nascita café where he meets Soichi and Misora Isurugi. While he attempts to contact his fiancée, he learns that Kasumi has been turned into the Burn Smash by Night Rogue. With no other way to save her, Banjo permits Sento to peacefully put her down. Once Build briefly separated Kasumi from the Smash, it was long enough for Banjo said his goodbyes to the woman he loved. Sento extracted her essence into the Dragon Fullbottle to which he gives it to Banjo as a memento of his beloved.
Banjo would continue to stick around with Sento, believing he would be the "Best Match" to regain his memories. Through Sawa Takigawa's investigations, the pair searched for Masahiro Nabeshima, a man with a connection to Katsuragi's murder and Banjo's jailbreak, but reached a dead end after Nabeshima's memories were temporarily erased. While continuing to search for more leads, Banjo learned Katsuragi was the creator of the Build Driver and most of Nebula Gas related weaponry. While Banjo and Sento debated whether Katsuragi's intentions for Build was intended for "justice" or a "weapon", Blood Stalk would eventually reveal that Katsuragi is actually alive and hidden.
When most of the Fullbottles were taken by Night Rogue, leaving only the Lock and Dragon Fullbottles, Sento thought of a way for Banjo to transform by synchronizing with the Cross-Z Dragon as he was about to reach Hazard Level 3. Banjo eventually transformed into Kamen Rider Cross-Z for the first time, using the power of the Cross-Z Dragon and Dragon Fullbottle to overwhelm Night Rogue and the Stretch Smash. He was later surprised to learn the monster's identity was none other than Sawa, who revealed herself as a spy for Namba Heavy Industries. Sometime later, Sento created a second Build Driver for him to fight as Build's partner against the Smash.
Right after Gentoku Himuro's defeat, Banjo was present to hear him reveal that Sento was previously Takumi Katsuragi. It was revealed Blood Stalk erased Takumi Katsuragi's memories and switched his and Taro Satou's appearances. This meant when Banjo entered Katsuragi's apartment, he saw Taro Sato's corpse under Katsuragi's appearance. Banjo's relationship with Sento ended up becoming strained after blaming Sento for the troubles that befell his life. When Banjo engaged the Smash attacking the city, he would be present to witness Sento finding his confidence to accept responsibility as his crimes, resolving to do right what the Devil's Scientist did wrong.
===Kamen Rider Heisei Generations Final: Build & Ex-Aid with Legend Riders===
One day, Banjo begins to question his purpose as a Kamen Rider. Kamen Rider Cross-Z later fights the Nebula Bugster attacking a power plant. After Build accessed the Doctor and Game Bottles to change into an form resembling Ex-Aid, Banjo tried but failed to use RabbitTank Sparkling much to Sento's displeasure. After Left Kaiser appeared and escaped using Engima, Cross-Z runs after him, he is transported into another world where the Sky Wall never existed.
When Banjo arrived to Seito University Hospital, he questions about the world around him but meets with Emu Hojo, who assumed Banjo to be "Build" after noticing him sporting his Build Driver. As it became apparent with Kaisei Mogami's goals to smash his native Earth and Ex-Aid's, Banjo accompanied Emu as they fought against Right Kaiser. As he continued exploring Ex-Aid's world, he would meet previous Riders like Takeru Tenkuji (Ghost), Eiji Hino (OOO), and Gentaro Kisaragi (Fourze) and learned of their motivations for fighting. 
Banjo would remain in contact with Sento as the Kamen Riders continued to stop the Engima. As the two Earths approached, Sento and Parado landed in Ex-Aid's world. While the heroes continued fighting Bikaiser's forces, Banjo realized his purpose to become a Kamen Rider, to fight for those who believe in him as Cross-Z. He later delivers the RabbitTank Sparkling back to Sento before facing the Foundation X Guardians. After Build and Cross-Z say their goodbyes to the Kamen Riders, they return back to their native Earth.
===The Japanese Civil War===
With Faust's dissolution in Touto, the starving nation of Hokuto declared war on Touto by sending an army of forces to secure the Pandora Box. Banjo and Sento voluntarily assisted Touto's government to protect the nation, but are forced to comply with Gentoku Himuro's orders. Cross-Z and Build would encounter Kamen Rider Grease, Kazumi Sawatari, and the Hokuto Sanbagarasu who are Hokuto's forces intent to take the Fullbottles. Furthermore, Banjo would take the Slash Driver that Sento created to become Kamen Rider Cross-Z Charge, causing his raging emotions to spiral out of control. Banjo would engage in a minor rivalry with Grease as they would often fight each other during every encounter.
As Sento was falling behind due to his Hazard Level being slightly lower, he managed to achieve the Hazard Trigger to evolve into the Hazard Forms with the Best Matches. Unfortunately, the Hazard Trigger's effect took hold and sent Sento into a mindless rage and in the process, took Aoba's life. The death of Aoba left Banjo mortified and would later apologize to Grease and the Hokuto Sanbagarasu in their next encounter. Sento was later chosen to represent Touto in a proxy one-on-one battle to end the war between Touto and Hokuto. After Build RabbitTank Hazard defeated Grease in battle, Cross-Z arrived to stop him from killing Kazumi on time and the war with Hokuto had came to a close.
Despite this victory, Seito had launched an invasion to Hokuto as its forces are led by the Washio brothers. Banjo and Sento joined forces with Kazumi Sawatari as Seito unveils Kamen Rider Rogue, revealed to be the previously exiled Gentoku Himuro. As Touto engaged in a three-on-three representative battle against Seito, Banjo participates in the second round against Fu Washio. Although Cross-Z was determinted to not let Sento be burdened, he was tricked by Fu Washio into believing his brother Rai would get executed, causing him to lose to Hell Bro's. Despite this loss, Banjo believed Sento will end the war and would ultimately be correct as Build manages to defeat Rogue in the final round. With Sento's victory, the war with Seito had seemingly come to a close.
===Discovering His Alien Origins===
Although the war between Touto and Seito had come to a close, the battle waged on and Banjo's Sclash Driver would be damaged by Blood Stalk in battle. After Banjo unintentionally creates a Fullbottle from the remains of the Dragon Sclashjelly, Sento created the Cross-Z Magma Knuckle in response to his growing power. As the Kamen Riders engage Seito's forces in the Pandora Tower, Banjo would learn from Gentoku Himuro that Blood Stalk ordered him to turn Kasumi into a Smash. Confronting Stalk over this, his anger allowed him access to transform into Cross-Z Magma. After returning to Touto, Banjo later learns about his extraterrestrial origins. Although this left him depressed, Banjo became determined to use his power as a Kamen Rider to fight for love and peace, the same ideals that Sento believes in and strongly holds onto.
After Evolto recovers the Evol-Driver and emerges as Kamen Rider Evol, he poisons Sento and will die within three days if he doesn't recieve the antidote. Banjo confronts Evolto and discovers Katsuragi lured him into his apartment to kill him. Nevertheless, the revelation did not stop him from fighting Evol and cure Sento from his condition. However, Evolto takes this opportunity to possess Banjo and can access Evol's Dragon-based Phase 2 form. While the Evolto-possessed Banjo proceeded on with completing the Pandora Tower, Evolto ceased his destruction due to the Evol Trigger still being incomplete. During an Build's attempts to sacrifice himself to destroy Evolto, Banjo is free from Evolto's inflence and switching over to Sento as his latest host.
With Sento now in Evolto's possession, Evolto accesses Evol's Rabbit-based Phase 3 form, but is still unable to activate his Evol-Trigger. Evolto's separation with Banjo rendered him unable to transform, his determination allowed him to reignite his alien genes and become Great Cross-Z. However, Evolto managed to complete the Evol-Trigger from the Kamen Riders' powers and access his Black Hole form, jettisoning Sento. However, his memories of being Sento are gone and is reverted back into Takumi Katsuragi, much to Banjo's surprise.
Katsuragi continued to assist the Riders in their efforts against Evolto, although he often denies Banjo's existence as he shares Evolto's DNA. Banjo had also started to see visions of the Mars' destruction, as he was receiving Evolto's memories. After sparing with Kazumi as they prepare themselves for Evolto, Banjo continued to fight Seito's forces as Great Cross-Z. After seeing Katsuragi failing to activate the Genius Fullbottle, Banjo told him how the lacked spirit and the great things about Sento. His words allowed the Devil's Scientist to regain his memories of Sento, causing an elated Banjo to sigh in relief. He would be present to witness Sento's first transformation in Kamen Rider Build Genius Form.
===Crossing The Threshold===
The Kamen Riders continue to fight Evolto in the pursuit of the Lost Bottles, Banjo would continue to experience an increasing amount of Evolto's past memories, triggered by Kamen Rider Evol's use of the Black Hole form. After recovering the Dragon Fullbottle from MadRogue, he would reach Hazard Level 7. The Dragon Fullbottle would occasionally evolve into the Silver Dragon Fullbottle as a result of Banjo's increasing power.
When Sento's biological father, Shinobu Katsuragi, resurfaces as another Kamen Rider Build and had the Vernage-possessed Misora transformed into becoming the CD Smash, Sento still hesitated in fighting against his father until Banjo gave him the confidence to continue fighting. Ultimately by working together, Sento and Banjo defeat Shinobu, with Vernage giving some of her powers to Banjo which also stops his episodes entirely. In response to this new power, Sento constructed the Blizzard Knuckle as another tool to defeat Evolto, but Banjo would fail in his attempt to transform with it. When Sento attempted to fight Evolto alone, Banjo along with Kazumi and Gentoku accompanied him in the ensuing fight with Evolto. While Cross-Z uses the Blizzard Knuckle with the Silver Dragon Fullbottle to unleash a devastating attack on Evolto, this still did not defeat Evolto for good.
===Kamen Rider Build: Be The One===
Banjo received a mysterious invitation from the Governor of Hokuto, Mitsuomi Gohara. Gobara revealed himself as a member of the Blood Tribe and the same race as Evolto. Banjo was angered that he was the one to suggested Evolto having his fiancée Kasumi Ogura into a Smash. After being defeated by Gobara as the Zebra Lost Smash, Kengo Ino brainwashed Banjo and compelled him to turn against Sento. Banjo also provided the Seito Governor with his Great Cross-Z Dragon and Build Driver, to allow Kengo Ino to become Kamen Rider Blood, combining with Banjo and his fellow Blood Tribe members.
When Sento confronted Kamen Rider Blood at the station square, Build Genius Form was able to land a blow that separated Banjo from him, later curing Banjo from his brainwashing. Knowing that a pair of Hazard Level 7 Fullbottles could defeat Blood, Misora channeled Vernage's power to combine the Gold Rabbit and Silver Dragon Fullbottles, as well as the Genius Bottle, to allow Banjo and Sento to fuse into Kamen Rider Build Cross-ZBuild Form. Ultimately, this new power allowed them to vanquish Kamen Rider Blood and free his compulsion over the Japanese populace.
===Final Confrontation with Evolto===
Evolto continued to collect the Lost Bottles to complete the Black Panel to evolve into a horrifying new monster form and announcing his intention to destroy Earth. Banjo would join in Sento's plan to use the White Panel to merge their world with one where the Sky Wall did not exist, using Evolto himself as the catalyst. Shortly after Evolto's national television broadcast, the Kamen Riders raced up to Pandora Tower. Kazumi and Gentoku stay behind to fight Evolto's replicants, while rest of the team awaited for Evolto at the top, later learning of Kazumi's death from becoming Grease Blizzard, with Banjo beaten down over the loss of his comrade.
The three remaining Riders transform and charge at Evolto, who was unimpressed at their performance and takes an opportunity to transform back into his monster form. Banjo and Sento watch as Gentoku sacrifices himself to immobilize Evolto, allowing Sento to trap Evolto and tether the worlds. However at the last second, Evolto grabs Banjo and drags him into the ripple between the two Earths. Sento gives pursuit and faces off against Evolto one last time, with Banjo immobilizing the alien and giving him his Silver Dragon Fullbottle. After Sento accesses the RabbitDragon form to vanquish Evolto once and for all. The energy begins the fusion, and both Banjo and Sento are sent flying by a tornado. The two worlds merge, finally bringing peace.
===New World===
After Sento succeeded in the creation the New World, we explores this new reality and meets a black-haired Banjo living a happy life with Kasumi. While Sento laments how there's nobody else in the previous world who still remembers him or his good deeds, the old world Banjo appears and Sento discovered since he still has Evolto's DNA, it resulted in a paradox where there are two Ryuga Banjos in the same Earth. As the duo departed in Machine Builder, they begin chronicling their journey into a 49 episode script, with Banjo butting in on the narrations.
===NEW WORLD: CROSS-Z===
Banjo was tasked to sell Sento's inventions at the marketplace, much to disappointing results. He meets a meets a school teacher named Yui Mabuchi who hazily remembers Cross-Z. Suddenly, Banjo gets attacked by Killbus who targets him for carrying Evolto's genes. Upon reactivating the Pandora Box, those experimented with Nebula Gas regaining their previous world memories and Evolto resurfacing. While angered by this, Yui had regained her memories and is angered at Banjo for abandoning her and her students in the previous world. Banjo has no option except cooperate with Evolto to defeat Killbus. Although Cross-Z Charge and Blood Stalk battle Killbus, they were easily overwhelmed and Killbus defeats Evolto, who leaves the Dragon Evolbottle behind.
While he manages to withdraw with Kazumi and Gentoku's assistance, Sento analyzed the Dragon Evolbottle to processes the Banjo needs a new power-up item to amplify Evolto's genes to defeat Killbus. This carries the risk of reviving Evolto at full power along with destroying Banjo's body, a necessary risk that he was willing to take. As Killbus demands for Banjo to battle him, Cross-Z arrives with Grease and Rogue to battle Kamen Rider Killbus, who generates a new battlefield. With Evolto's cooperation, the two merge into Kamen Rider Cross-ZEvol to vanquish Killbus for good. After the victory, Evolto subsequently left the planet promising to return at full strength. Meanwhile, Yui kisses Banjo on the cheek much to Kazumi and Gentoku's jealousy. The next day, Banjo and Yui had begun dating and trying to sell Sento's toys in the marketplace.
===NEW WORLD: GREASE===
While Sento helps Nariaki Utsumi raise his Hazard Level with a Nebula Gas chamber, Banjo get ambushed by Down Fall's Phantom Crusher. While Cross-Z and Build engage the Phantom Crusher, he negates their transformation and takes both the Hazard Trigger and White Panel. Banjo joined with Sento and Sawa as they head out to Takumi Katsuragi's lab while the Hokuto Sanbagarasu head out to act as Misora's bodyguards.
Before Phantom Build alongside his Guardians and Smashes can finish him off, however, Banjo arrives and hands Kazumi the Perfect Kingdom adapter along with the Hokuto Sanbagarasu's dog tags. Taking them, Kazumi resolves to fight. They are joined by Sento, Utsumi, and Gentoku, and they all transform into Kamen Riders. After Kazumi transforms into Grease Perfect Kingdom, Cross-Z Magma initially fought alongside him but later goes to save Misora.
==Other Events==
===Kamen Rider Heisei Generations Forever===
A powerful Time Jacker named Tid appears and creates two powerful warriors, Another Double and Another Den-O and orders them to pursue a young boy named Shingo. Cross-Z and Build are drawn to Ataru's world to protect Shingo from the Another Riders, while assisted by Grease and Rogue despite them suddenly losing their memories. Together with Sougo Tokiwa and his comrades, Banjo continues to continue fighting Tid's forces to stop him from destroying the Heisei Rider legacy, eventually working alongside Geiz in battle.

Banjo is an extremely hot-blooded and impulsive man who tends to lash out quickly. He is shown to be easily provoked and startled in most situations, which is often joked on by Sento. While nowhere near as intelligent as Sento, Banjo prefers to confront problems directly using his fists and doesn't want to involve other people in his own problems. Also, unlike Sento, he does not overthink things, preferring to use common sense, as shown when he was easily able to guess two Best Matches on his own. His impulsiveness increased following his initial usage of the Sclash Driver, which imprinted him with the single task of getting stronger and beating down his opponent. These side effects also remove his rationality to make decisions, but he is able to overcome these weaknesses with his strong will to save Sento from rampaging with the Hazard Trigger. After discovering his relationship with Evolto, the awakening of the latter's memories causes Banjo to become more violent and go berserk. These side effects have been nullified however, after Vernage's DNA was implemented into Banjo's body, while trying to save Misora. 
Beneath his tough exterior is an honest, selfless and honorable individual who cheated during a match to gain the money needed for his fiancée's medical treatments, causing him to receive a lifelong ban from the ring. He is extremely protective to those who he trusts, as he attacked Blood Stalk out of anger for the sake of both Sento and Misora, completely disregarding the fact that Stalk framed him. He also directly apologized to Sento on his behalf to the remaining Hokuto Sanbagarasu, partially blaming himself due to letting Sento use the Hazard Trigger for his own sake.
Banjo appears to hold a lot of fondness for his childhood, as whenever he describes the circumstances of his birth, a bright smile is always on his face.
==Video Game Appearances==
== Powers and Abilities ==
===Powers===
*Hybrid Physiology: Banjo's body was created from a piece of Evolto brought back from a Martian probe. This allows him to utilize the Pandora Box's power like Stalk, albeit unintentionally. His eyes glow red when he uses his powers. As Banjo was born from the mysteries of the human body, he possesses a power capable of eventually surpassing Evolto himself, a point acknowledged by Evolto in Build NEW WORLD: Kamen Rider Cross-Z.
**Hazard Level: Initially, Banjo's Hazard Level had been above 2.0, allowing him to retain his humanity after his exposure to Nebula Gas while still gaining physiological powers from it. To be noted is that as his Hazard Level increases, his physical condition increases as well. According to Blood Stalk, while fighting, Banjo can raise his Hazard Level, having raised it as far as 2.7 in one of their fights. Eventually, he was able to raise his Hazard Level to 3.0, which is high enough to use the Build Driver. Continued fighting as Cross-Z allowed him to quickly raise it even further to 4.0, enabling him to use the Sclash Driver. During his fight with Evolto before being possessed by him, his Hazard Level had been measured to be at 4.7, 4.9, and finally 5, a Hazard Level that an ordinary human cannot supposedly achieve unless via special means. After remembering the destruction of Mars when he was part of Evolto, Banjo's Hazard Level rose to 7.
***Hazard Level Escalation: Due to being created from Evolto, Banjo's Hazard Level grows at a faster rate than any other Kamen Rider, to the point where his strength grows noticeably in a single fight, forcing his opponents to resort to low blows. His anger or determination, in particular, will raise his Hazard Level tremendously.
**Superhuman Strength: Banjo has displayed superhuman strength. As his Hazard Level increases, his strength increases as well. Hence, he was able to fight off numerous Guardians on his own and break metal chains with his bare hands. He could even land a considerable damage on Blood Stalk with the help of Dragon Fullbottle. In Build NEW WORLD: Kamen Rider Cross-Z, he is able to knock Evolto several feet back without the help of any equipment, though at that time Evolto is only in his Blood Stalk form. He is also shown to use his arm to block a full forced blow from a Smash created by Killbus and knock it back with the help of Cross-Z Magma Knuckle.
**Pandora Box Manipulation: His true alien origin allows him to manipulate the structure of the Sky Wall by touching the Pandora Box. 
*Fullbottle Augmentation: By holding a Fullbottle or Evolbottle in his hand while untransformed, Banjo can gain abilities based on said Fullbottle's traits:
**Dragon Fullbottle: Banjo's punches give off powerful shockwaves. Notably, his strong synchronization with the Dragon Fullbottle causes his power to increase with each use. Currently, Banjo's synchronization is high enough that he can defeat a Hazard Smash while untransformed.
**Dragon/Great Dragon Evolbottle: Similar to the effects of the normal Dragon Fullbottle, Banjo can perform powerful punches. However, Banjo's punches are now strong enough that they are able to damage Kamen Rider Evol. 
* Smash Energy Signature: After he had escaped after being exposed to the Nebula Gas, Banjo gave off an energy signature similar to a Smash, which had alerted Sento to his location. 
===Abilities===
*Master Martial Artist: Banjo is a master hand-to-hand combat and martial artist, having extensive levels of melee combat knowledge as well as having fought professionally before being banned for life after a match fixing incident. His combat skills gradually enhanced as he fought against numerous Smash as Kamen Rider Cross-Z throughout the series. Even without transforming, he was able to fight against numerous Guardians with or without the Dragon Fullbottle effortlessly. He could even fight against Blood Stalk with the Dragon Fullbottle although the latter was holding back. In Kamen Rider Heisei Generations Final: Build & Ex-Aid with Legend Riders, Banjo was able to hold against Gamel and Mezool untransformed.
===Former Weaknesses===
*Sclash Driver: Although the Sclash Driver can grant Banjo tremendous power, prolonged usage can slowly turn him into a more aggressive person and give him an addiction to battle. Furthermore, the driver administers electrical shockwaves to the user after a period of time, canceling his transformation and rendering him unconscious. After learning from Sawa that Sento has built a failsafe to destroy the Hazard Trigger and kill himself, Banjo overcomes his guilt and turns into Cross-Z Charge to stop Sento in his HawkGatling Hazard form. During the fight, the Sclash Driver begins to increase his aggressiveness, yet he manages to overcome it by reminding himself to save Sento, thus gaining control over his Cross-Z Charge form. 
*Evolto's Memories: Because a part of Evolto had merged with Banjo when he was still in his mother's womb, Banjo shares his memories. Banjou normally cannot recall these memories, but once Evolto attained his complete form again, he started suddenly experiencing fractions of them. Seeing memories of Evolto's destruction of Mars caused Banjo to become incredibly aggressive, to the point where he continued to attack enemies that had already been defeated and came close to killing opponents. However, he is no longer susceptible to these memories after Sento used Genius Form to transfer Vernage from Misora's body to Banjo's, leading to Vernage's power neutralizing Evolto's effect on Banjo.
*Cross-Z Magma Form: As Cross-Z Magma, Banjo will heat up over the course of the battle, eventually resulting in him producing fire and the surface of his suit becoming similar to lava. Normally the heat is a minor discomfort and at worst forces him out of his transformation, but repeatedly using the form places Banjo at risk of more serious harm. Banjo seemingly does not suffer from this side effect anymore.

**Sento Kiryu/Kamen Rider Build: In the beginning, they started off as enemies and worked together at a rocky start. But in time, they grew closer as the best of friends and brothers. But despite learning, Sento's alter ego, he never forgave him as Katsuragi for the death of his beloved. Throughout the wars with Hokuto and Seito, their bond still remained intact. Sento's been the brain, while Banjo the brawn, as they always quarrel.

Throughout the course of the movie, she slowly started to grow fond of him and even ended up as his new girlfriend in the end.
*Soichi Isurugi: Once an ally until he was revealed to be Blood Stalk and the one who set up the murder of Katsuragi, until later on, he learned that he's possessed by Evolto.
*Takumi Katsuragi: Takumi was thought to have died by Banjo's, but was actually Taro Satou’s body replaced with his face altered. When Sento's memories as Katsuragi returned after being possessed by Evolto, Katsuragi saw him as an enemy related to Evolto and never treating him as a friend.

==Notes==
*Banjo's characteristics are near polar-opposites of Sento Kiryu, as Banjo possesses high-stamina prowess that can fend off inhumane monsters while lacking a standard-level intellect, while Sento possesses a genius-level intellect to create gadgets as part of his force but doesn't have Banjo's high-level stamina or strength. Simply put, Sento is the brain, and Banjo is the brawn. 
**The duo often make some conversations, with Sento serving as the and Banjo as the , as a way to reflect the characteristics.
*Kamen Rider Cross-Z's design is that of Build's Dragon Halfbody, made into a full Rider design with distinct armor added on top. Even his arms and legs are asymmetrical, as orange flames are added only to the limbs that aren't shared with Build.
*Cross-Z Charge's transformation begins with an incomplete suit that lacks the transparent chest piece and faceplate, as well as the spout bag-themed shoulder pads. These elements are formed once Variable Jelly is secreted from several ports on the suit and solidifies.
