Taiga Hanaya

Taiga Hanaya (花家 大我) is Kamen Rider Snipe (仮面ライダースナイプ). He is a 29-year old unlicensed doctor, who was once a member of the radiology department at the Seito University Hospital and the original Kamen Rider for CR. Losing his medical license after failing to save a patient, Taiga now collects Rider Gashats to become the rumored "Super Doctor". He is also known as the "Doctor of Darkness" (闇のドクター).

He later becomes Kamen Rider Cronus (仮面ライダークロノス).

Past
Taiga was originally a renowned genius radiologist at the Seito University Hospital, who is capable of detecting and removing cancer cells in an instant. At the time of Zero Day, he was chosen to be a Kamen Rider for CR after accidentally discovering the essence of Bugster Viruses through conventional methods. Despite having passed the examination to become a Kamen Rider, Taiga refused to take it until the death of his coworker Maki forced him to accept the offer.

When the Proto Bang Bang Shooting Gashat began to hurt Taiga's mind and body in the process, Taiga was temporarily prohibited from transforming. Despite this, Taiga was still adamant on saving his patient's life, to the point where he ignored orders to stand down and reclaimed the Gashat and Gamer Driver from Kuroto Dan, just as the latter had planned.

Ultimately, Taiga fell from grace by this side effect after failing to defeat Graphite, a Bugster that spawned from Saki Momose. His defeat cost Saki her life, and his doctor's license was subsequently revoked for disobeying orders, with the Ministry having decided that Taiga had become overly obsessed with the power of the Gashats. Saki's boyfriend, Hiiro Kagami, has since held a grudge against Taiga and blames him for Saki's death. Taiga would eventually lose all hope in saving others as a doctor and a Kamen Rider, eventually going on to believe that clearing the games was the only important thing to him. To his shock, the side effects of the Proto Gashats had caused his hair to turn white as well.

Second Bugster Outbreak
Taiga observed Ex-Aid's first fight against the Bugster from afar, using a rifle scope as a means from seeing afar. He then mimicked shooting Ex-Aid.

He purchased his own Gamer Driver and Bang Bang Shooting Gashat from Genm Corp. with large piles of cash. When complimented by Kuroto Dan, he simply said that Dan needed a large amount of money to make new games.

Debut As Snipe
Sometime later, Taiga was confronted by Graphite. Before Taiga could transform to fight, Parado appeared, warning Graphite against doing something rash and making a bet with Taiga to see who can clear the ten games first.

By chance, Taiga overheard Emu trying to confront one of his patients, a boy named Yuki who was infected with the Bugster virus. Taiga's presence aggravated Yuki due to the latter's iatrophobia, activating the giant Bugster. Taiga transformed into Snipe Shooting Gamer Level 1 and quickly extracted the Bugster, Revol, from Yuki before proceeding to fight the virus. However, Yuki's fear of doctors was only heightened, and Revol's strength multiplied. Despite Ex-Aid's protest, Snipe continued fighting. After finishing off more of Revol's troops, Taiga confronted Emu, noticing his personality change as Ex-Aid and saying that they'll play again.

Emu found Taiga in an abandoned hospital, the latter expecting the former. Taiga refused to stay out of Yuki's case, saying he would do what he wanted to do, and that his only concern was to collect all 10 Gashats to gain the power to destroy the Bugsters permanently. Taiga proposed a wager: the two would fight to see who could defeat Revol first, the prize being the other Rider's Gashat.

As Taiga expected, the Bugsters intruded the hospital to get him and Emu. Taiga handled several Busgters bare-handed before transforming into Snipe Shooting Gamer Level 2, beginning the challenge between him and Ex-Aid. However, Brave intervened by attacking Snipe. Their fight stopped momentarily when Ex-Aid and Brave reminds them of Revol, the primary target.

Snipe is able to avoid getting damaged, but Brave and Ex-Aid are almost brought to Game Over by Revol clones generated by the stronger Revol. Nevertheless, Taiga remained calm, finishing the real Revol using Bang Bang Critical Finish after Ex-Aid defeats the clones.

After the battle, Taiga claimed the Mighty Action X Gashat, telling Emu mockingly that he's open for a rematch if he wants it back; that is, if he can transform.

Remembering the passcode from his time as a CR doctor, Taiga entered CR where he found Kuroto Dan. Realizing that Dan's VR device was on his person, Dan explaining that he wished to record Emu's specs again for a tune up, Taiga informed him that he had confiscated Emu's Mighty Action X Gashat for himself. While a disappointed Dan attempt to leave, Taiga stopped him by revealing his knowledge that the prototype Gashats were resposnible for Zero Day, threatening to expose the news to the public if Dan refused to cooperate. Leaving Dan with no other choice, Taiga received a one-time VR simulation of the Shooting Gamer from Dan. Instructed by Dan within the simulation, Taiga transformed into Kamen Rider Snipe Shooting Gamer from Level 1 to Level 2 before activating his Critical Strike finisher using the Kimewaza Slot Holder. Having cleared the simulation, Taiga requested Dan to send the data to him. Before leave, Taiga proclaimed that he was ready for another rematch with Emu and asked Dan to relay this message when he next meets with him.

Lazer debut
Soon after, Taiga was approached in the hospital by coroner Kiriya Kujo, the latter asking for a duel. Kiriya brought him to the latest Bugster patient, Yoshitaka Nishiwaki, who was being monitored by CR, and was quickly overtaken by the Motors Bugster. Kiriya proposed that if he destroyed the Bugster, he would take back Emu's Gashat. Taiga agrees, but says that Kiriya must relinquish his Gashat if he loses. Taiga and Kiriya transformed into Snipe Shooting Gamer Level 1 and Lazer Bike Gamer Level 1, respectively, and began fighting the Bugster.

Eventually, they were able to extract the Bugster. However, Brave entered the fight and kept Snipe from chasing after the Bugster, which allowed Lazer to steal the Mighty Action X Gashat for Emu. Brave and Snipe continued to fight until they were interrupted by the black Ex-Aid, who depleted their health bars by using the Sports Gamer before disappearing. Taiga remarks about the increasing field of candidates for the Super Doctor position before stumbling away.

The Stolen Gashats
Taiga mocked Dan to beef up Genm Corporation's security as the latter consulted him and Kiriya to reclaim the four new Gashats that were stolen from Genm Corporation, giving them the special stethoscopes to aid them. Taiga agreed to take back the Gashats, but warned the CEO that he would be keeping any Gashats he found for himself before he left.

He eventually found the Collabos Bugster at a university, requesting a fight with the other three Riders for the Gekitotsu Robots Gashat ownership. The black Ex-Aid appeared again, this time in Sports Action Gamer Level 3, promising to take on all the Riders. Brave and Snipe transformed to fight the Bugster, while Lazer went after the black Ex-Aid. Despite their best efforts, the Riders were overwhelmed, and Brave and Lazer were forced to de-transform. Eventually, the Gashat thief reveals himself to be Graphite. After he learns of this, Snipe becomes enraged and attacks Graphite with his Gashacon Magnum. However, Graphite manages to retaliate. As Graphite is about to unleash Gekidoryuga, Snipe reverts into Shooting Gamer Level 1 and uses his energy bullet form to counter it. The recoil from Gekidoryuga is so high, however, that Snipe is forced to cancel his transformation. Taiga then witnesses Emu successfully defeating the Robots Bugster using Mighty Critical Finish and using the newly-acquired Gashat to become Robot Action Gamer Level 3 and defeat Genm.

Taiga confronts Graphite, already transformed into Snipe Shooting Gamer Level 2. He exclaims that he'll finish what he begin five years ago right now. As Graphite uses Gekidoryuga, Snipe and Brave attempt a counter attack, but with no avail. As Genm orders Graphite to retreat, Taiga cancels his transformation and prepares to leave. But, Hiiro asks him if Graphite is indeed the Bugster Taiga failed to kill five years ago. Paying him no need, he mockingly said that he'd been forgetting things already. Hiiro then attempts to punch him, but he easily stopped him by holding Hiiro's fist using his right hand. As Emu stops their fights, Taiga challenges Hiiro to finish Graphite off and admits that it's indeed Graphite who made him fall from grace before he left.

Taiga, later seen on the top of a building, monitors Hiiro using his riffle scope. As Hiiro obtains the DoReMiFa Beat Gashat by defeating Beat Collabos and also defeating Graphite, Taiga begrudgingly warned Hiiro to not be so cocky before leaving.

He is shown to be fighting the Jet Collabos on his own in order to obtain the Jet Combat Gashat, but failed to defeat it due to the Bugster's flying ability and lets it escape. Taiga then swore to claim the Gashat later.

Becoming Combat Shooting Gamer Level 3
Taiga is seen when he overheard about Shiori conversation with Asuna. He then later found Combat Collabos on the top of a factory. Taiga explained to the viewer that the Gashat that the bugster have is Jet Combat, and he'll be the one who take it. Taiga then transform into Snipe Shooting Gamer Level 2 and shortly, he able to claim the Gashat without killing the Collabos using Gashacon Magnum Rifle mode. Using the Bugster as a bait, Snipe taunts Emu to accept his challenge if he want to save Yoshio, before Taiga left.

The next day, as Emu and Hiiro appeared to confront Taiga. Taiga then begin his mission to claim the Gashats. All of them transformed into Ex-Aid Action Gamer Level 2, Brave Quest Gamer Level 2 and Snipe Shooting Gamer Level 2 respectively. As joint attack of Ex-Aid and Brave overpower him. Snipe then decide to use his newly acquired Gashat to become Combat Shooting Gamer Level 3. After he uses the Shrink Energy Item on Prime Collabos, Snipe then proceed to counter Brave and Ex-Aid while both of them transformed into Level 3. Using his Flight Capability to evade and Gatling Combats to attack, Snipe manage to knock Brave into Quest Gamer Level 2 and claim DoReMiFa Beat Gashat. Snipe then released Prime Collabos to distract Ex-Aid, while Snipe prepared his Jet Critical Strike. Snipe claimed that the world only needed him as the only Kamen Rider, then proceeding to defeat Ex-Aid Robot Action Gamer Level 3 and Prime Collabos. Snipe claimed the Gekitotsu Robots Gashat, thus completing his mission.

While Taiga shows a satisfied expression with his battle loot, Emu said that his Gashat isn't a toy, but rather a tool to save patients. Taiga instead said that Emu had no idea regarding of the responsibility of wearing Gamer Driver and using Rider Gashat before he left.

The Drago Knight Hunters and The Demise of Graphite


While Snipe Combat Shooting Gamer Level 3 is busy fighting Graphite along with Brave Quest Gamer Level 2, Lazer Chambara Bike Gamer Level 3 joins the fray. However, due to Graphite's increased strength from the Proto Drago Knight Hunter Z Gashat, combined with Brave and Snipe's squabbling, it rendered the three Riders no match for the Bugster. Lazer and Brave were able to snatch the Gekitotsu Robots and DoReMiFa Beat Gashats from Snipe during the commotion, much to Snipe's chagrin. Back in the real world, the three were approached by the apologetic Emu, who asked for their help in using the Drago Knight Hunter Z Gashat. Hiiro refused out of pride as a surgeon, Taiga wasn't interested in playing doctor, and Kiriya cited Emu's condition as a reason not to trust him. Later that night, Emu called Taiga, offering him the Drago Knight Hunter Z Gashat. Taiga arrived the next day only to find that Emu had tricked him, as Emu had secretly made a deal with Kiriya and Hiiro as well. Emu finally used his Gamer persona and offered the Gashat to whomever could beat him first. Transforming into Snipe Combat Shooting Gamer Level 3, Taiga joined the other two Riders in fighting Ex-Aid Hunter Action Gamer Level 5 Full Dragon. Eventually, they were able to separate the Hunter Gamer from Ex-Aid and attacked it. Much to their surprise, Hunter Gamer split into four virtual Gashats, one for each Rider. Ex-Aid explained his true plan: getting the four together to see who had the power to take out Graphite. As Ex-Aid changes the stage, Graphite appeared and quickly transformed into Dark Graphite. Taiga, along with the other doctor riders, transformed into their Level 5 forms. Using their new Levels, the Riders were finally able to fight on par with Graphite, although their lack of cohesion got in the way. Ultimately, the four were able to defeat Graphite once and for all, despite none of them agreeing on who delivered the final blow.

The Dr. Pac-Man Incident
With his fellow doctors and Kamen Rider Ghost's allies, Snipe fought the Next Genome Institute.

Assuming the Xevious Gamer
"Final score: 9,999,990 points. A hearty mission complete."

- Snipe's proclamation after a finisher in Xevious Shooting Gamer

Taiga, along with Hiiro, confronts the revived "Dr. Pac-Man" who had taken Emu away from Genm, both vowing to defeat him again. When the three doctors are met by Genm and the three copy Kamen Riders that he had summoned, "Dr. Pac-Man" provides the trio with the Bandai Namco Gashats, with Taiga receiving the Xevious Gashat. Transforming, Snipe Shooting Gamer Level 2 faces Kamen Rider OOO in a brief skirmish before using his new Gashat to assume Xevious Shooting Gamer, generating a Game Area in which he finds himself engaged in aerial combat against Kamen Rider Fourze using the Rocket and Gatling Modules. Ultimately prevailing in the dogfight, Snipe performs Xevious's Critical Strike to defeat the opposing Kamen Rider.

Alongside Brave, Snipe soon caught up with Ex-Aid as he recovered the Ganbarizing Gashat, both intending to claim it for themselves only to be eluded by "Dr. Pac-Man" who snatched the Gashat as quickly as he arrived, adding it to his quartet of Bandai Namco Gashats. It was at this point that Taiga realized that the three of them had been manipulated all along, a deduction immediately confirmed when "Dr. Pac-Man" was joined by the black Ex-Aid who, using the Ganbarizing Gashat to bestow upon himself the power of the first seventeen Heisei Riders, took the three doctor Riders by shock as he was able to defeat them with a single Critical Strike Rider Kick before taking his leave.

Fighting Genm Zombie Gamer Level X
"Ex-Aid. You have Game Syndrome."

- Taiga mutters to himself about Emu's Bugster Virus.

Frustrated and bewildered by Genm, Taiga searched in vain for any information he could online about the ex-CEO. His thoughts were interrupted when Nico appeared again asking for his help to defeat M and ignoring Taiga's demand that she leave. Soon after, Taiga went to confront Kuroto, having deduced that Lazer was killed in order to hide what he found about Ex-Aid. Taiga transformed into Snipe, but even at Level 3 he (along with Brave) was no match for either Genm Lv 10 or the upgraded Aranbura. He and Brave were quickly knocked out of their transformation. However, before Genm could steal their Gashats, Emu arrived with a mysterious black Gashat. Much to everyone's shock, Emu was not only able to create an entirely new game from the blank Gashat, but split into two separate bodies.

Bewildered by Ex-Aid becoming two, Taiga was once again approached by Nico. While showing further annoyance due to her appearance, Taiga learned that Emu had never used the pronoun "boku" when referring to himself in the past, thus noticing that is was similar to Emu's personality change while playing games. The following day, Taiga observed Ex-Aid's fight against Aranbura and Genm, managing to get a blood sample from the unconscious Emu after the battle. Upon scanning it, Taiga realized that Emu had the Bugster virus inside his body.

Fighting Para-Dx
Taiga finally lost his patience with Nico after she tried moving into his hospital.

"You're a little prince who's never experienced failure. If you continue performing operations in that condition...you might become like me. Are you sure about it? I've nothing to lose. That's why I've said it before...that I'm the only Kamen Rider needed."

- Taiga's reasoning to Hiiro before he left.

Chou Super Hero Taisen
When Poppy Pipopapo was pursued by the, Taiga engaged them alongside Emu and Hiiro, briefly fighting with and  before the fight was interrupted by the Galaxian ships.

Later, Snipe wielded the Hunter Gamer as he joined the Chou Shocker Taisen with various Kamen Riders and fighting against the Shocker army of the Game World led by Shocker Leader III.

The Bugster Horde
When Kuroto Dan's plot to revive in the Game World caused an army of Bugsters to perpetually revive and emerge into the real world, Snipe and Brave shared the Gashat Gear Dual β as they fought back the endless horde while Emu was sent from CR to the Game World to stop Dan. Brave assumed his Fantasy Gamer first before being beaten back, leaving Snipe to endure alone with the Simulation Gamer before rejoining him with the Hunter Gamer, at which point the horde ultimately dissipated in an instant as the destruction of the Game World brought about by Kazuma Kenzaki thwarted Dan's ambition to revive.

Ending Kamen Rider Chronicle
Standing alongside Ex-Aid and Brave in the face of Super Gamedeus and his Bugster Virus horde, Snipe Simulation Gamer engaged the Bugster bosses summoned by Masamune while taking care not to harm infected civilians, defeating Revol and Salty in defense of Nico. Soon enough, the infected were cured by Poppy as she sacrificed her own existence to neutralize Super Gamedeus's virus through Doctor Mighty XX. Among her last words, Poppy told Taiga to be nice to Nico and for Nico to look after Taiga. Snipe joined Ex-Aid and the other Riders in the fight against Super Gamedeus but was unable to affect the behemoth until Emu remembered Asuna's advice and rallied his fellow Riders in reverting to Level 1, allowing them to seperate Masamune from Super Gamedeus, which was neutralized by Doctor Mighty XX through the sacrifice of Parado. Masamune, however, still held the power of Cronus and, with the access to Emu's Muteki Gamer gone, declared that the doctor Riders would face a "Bad End."

At his strongest Level, Taiga engaged the elder Dan in one final stand with the other Riders only to be swiftly overwhelmed with their strongest Gashats flying loose. Initiating Pause, Cronus, seemingly victorious, was shockingly beaten back by Ex-Aid, who revealed that Parado's sacrifice had weakened him. Reverting to Level 2, Snipe and his fellow Riders ultimately succeeded in finally defeating Cronus, however, they were unable to stop Masamune from destroying the Rider Chronicle Master Gashat with himself in a final act of spite, robbing them of their chance to retrieve the Game Disease victims from the Proto Gashats. With the ordeal over, Taiga's clinic was been reinstated a medical center to treat the game illness. Looking around his office, Taiga fonds a Bang Bang Shooting pin left behind by Nico, who had returned to school. Listening to a televised speech given by Emu speech on behalf of the Ministry of Health, Taiga was touched to hear the name of Jiro Maki acknowledged among the victims of the Game Disease. Later, Taiga, preparing to treat the patients of the game illness, was met by a graduated Nico who volunteered to become his clinic's wanted assistant.

Personality
Taiga was originally a kind doctor who valued the lives of his patients and did whatever he could to make them smile. However, becoming a Kamen Rider would eventually change him, with his defeat at the hands of Graphite being the turning point, causing him to give up all hope.

As a result, he has become bitter, arrogant, and selfish, holding almost absolutely no concern for protecting individuals; he cares only about his obsessions of both collecting Gashats and achieving his revenge on the Bugsters. Clearing all the ten games became his main drive for fighting, and as such he would resort to any form of dirty tactics just to claim all of the Gashats. He would later view Saki's death with disdain as well, using that just to taunt Hiiro.

Taiga especially holds a strong animosity against Graphite, who cost him both his medical license and his credibility as a doctor. He would constantly find a way to settle things once and for all with Graphite. His hatred of the Bugster overshadows any concern for a patient's well-being. For him, the battles are competitions with his fellow Riders.

Despite willing to use dirty tactics to win, Taiga does have a sense of fair play as he did not try to take Emu's Gashat by force, nor did he think that Kiriya Kujo would take the Mighty Action X Gashat from him before even winning their bet. This however, didn't stop him for being provocative to fellow Riders. Similarly, while he kidnapped the Collabos Bugster to blackmail Ex-Aid and Brave, he did not demand them to directly surrender their Gashats to him, but instead wanted to win them through a fair battle.

Taiga believes that he is the only Kamen Rider the world needs, believing that he has nothing to lose unlike others. This mentality has also led him to prioritize defeating an enemy and keeping the Kamen Rider name, something which goes against the doctor ideals of Emu and Hiiro. Initially despising the other Riders, he would eventually gain respect for their resolve and strength, though his strong sense of responsibility meant that he would be willing to do anything to prevent the other doctors from going down the same path as he did, even if it meant sacrificing himself.

Meeting Nico Saiba would eventually change Taiga for the better, as his interactions with Nico would slowly guide him back to his conscience. When Nico faked being sick with the Game illness and when she became a Ride Player, he went to make sure she was alright, showing that he's at least willing to care about other people somewhat. Over time, his care for Nico grew to the point where he treats Nico as his own personal patient, getting worried whenever she's in danger. He would soon come to admit that despite having his license revoked, he still wanted to protect others as a doctor. By the end of the Kamen Rider Chronicle crisis, he has somewhat returned to his gentle nature, though at times he would react awkwardly to politeness.

Relationship

 * CR:
 * Emu Hojo: He and Emu developed a seemingly hostile rivalry. Taiga sees Emu as a tick, although he usually calls Emu as either the Genius Gamer or Ex-Aid. Emu, in return didn't like Taiga either, since Taiga stole his Gashats twice. After Kiriya's death at the hands of Kuroto, Taiga got the evidence Kiriya left behind such as Emu's secret related to his special past surgery by Kyotaro where both Kuroto and his father involved in, and found out who Emu exactly is. Taiga also shows some respect to Emu after he tries to save Nico.
 * Asuna Karino/Poppy Pipopapo: Asuna fears Taiga because of his brash yet calculative demeanor. Taiga is usually apathetic towards her in return.
 * Hiiro Kagami: Hiiro holds a grudge against him, since he is the man responsible for Saki's death, who is Hiiro's girlfriend. Taiga, in return also hates Hiiro, often provoking him if necessary. Later on, Taiga reminds Hiiro that he might end up becoming a broken and disgraced man like him if he's not careful with his ego. Upon Masamune Dan revealed to be an evil mastermind behind entire events all this time and being another Patient Zero besides Emu as a time manipulating Kamen Rider Cronus, when he able to steal the Proto Gashats which contains the Bugsters' former hosts including Saki as his hostages, Taiga fears that Hiiro will fall into Masamune's blackmailing tricks, which became true.  After Taiga was badly injured by Graphite, Hiiro decide to save him instead of killing him to save Saki. Taiga and Hiiro finally able to forgive each other and become comrades
 * Kiriya Kujo: Taiga didn't really like Kiriya, although he's a bit surprised about Kiriya's compability with the Gamer Driver. Kiriya usually pays him no heed in return. After Kiriya's death at the hands of Kuroto, Taiga continues the investigation of the information Kiriya left behind, regarding Emu's special past surgery performed by Kyotaro where Kuroto and his father Masamune were involved in.
 * Genm Corp.:
 * Kuroto Dan: Taiga often provokes Dan if necessary, although he's still oblivious about the fact that Dan is actually Genm, until Dan revealed himself to Taiga and three other doctor Riders once he got all battle data he needed, as Taiga and the other Riders are too late to notice and stop this scheme. In the past, Kuroto used Taiga and Jiro as his guinea pigs, most occasionally when Taiga used a Proto Gashat that he provided on just to gather battle data for Kamen Rider Chronicle. Because of this, Taiga's life was almost ruined that led him into the unlicensed doctor as he is now. However, these events granted Taiga some tricks and knowledge on how to resist the upcoming negative side-effects of the future Gashats quickly, such as when using his Level 50 form with the Gashat Gear Dual β.
 * Bugsters:
 * Graphite: Taiga sees Graphite as his number one nemesis, mainly because of the fact that he lost his doctor license. Taiga is always enraged whenever he confronts Graphite, and always tries to eliminate him at all costs, although Graphite always defeats him single-handedly. It was only by working together with the other Riders did he finally succeed in his revenge on Graphite, though he didn't want to admit it. During the Kamen Rider Chronicle crisis, he is shocked to learn that Graphite, being a fully-manifested Bugster, can be revived anytime, even after the latter's physical body being destroyed without having his Bugster virus debris absorbed into the Gashacon Bugvisor before. Graphite then challenges him to clear Kamen Rider Chronicle in order to be the same level as him now, and fight him one on one, which made Taiga swear to be the one to clear the game, while hiding the truth from Hiiro that Graphite had revived.
 * Civilians:
 * Nico Saiba: Nico wants to attract Taiga's attention so he can defeat the Genius Gamer M, but Taiga sees her as no more than an annoyance. However, as time passes, Taiga show some sort of care to her, despite he covered it with his arrogant persona, Nico ultimately does the same to him in return. After his fight with Lovrica, Taiga finally admits that Nico's presence is the one who made him happy, and that he wants her to not leave his side ever again, while promising that he will cure her Game Illness no matter how many times it will take, which Nico happily complies. Taiga also go as far to challenge Masamune by transforming into Cronus to save Nico. After Kamen Rider Chronicle incident is over, Nico become Taiga apprentice, much to Taiga initial chargrin.
