Yusuke Onodera

"This man is fighting so that no one else need to fight. Even when plunged alone in his darkness, he wants to make others smile. That what he believes! If he protects smiles, then I will protect his smile! Did you know? His smile is not bad."

- Tsukasa talking about Yusuke to N-Gamio-Zeda

Yusuke Onodera (小野寺 ユウスケ) is the resident of the World of Kuuga in Kamen Rider Decade. He has a very self-confident and gullible child-like personality, a stark contrast to the original incarnation of Kuuga, Yusuke Godai.

Yusuke supports the police in fighting the Gurongi and has feelings for Detective Ai Yashiro, as he fights to see her smile. When Yusuke first discovered the Arcle Belt, he was warned of Decade's existence as the "devil" by Narutaki.

Yusuke rarely engages in battle while journeying with Tsukasa. He does, however, act as a inspirational figure to the other Riders, as can be seen with his aiding of Wataru, as well as his actions in the other Riders' worlds. While traveling with Tsukasa, he acts as his personal assistant.

World of Kuuga
After killing the Gurongi Me-Gyarido-Gi and Ra-Dorudo-Gu, Yusuke answers Ai's call about another Gurongi being spotted. After witnessing Decade defeat another Gurongi, Ai and Yusuke meet Tsukasa, who offers them his help as a policeman. Although Yusuke seems to be annoyed by this, Tsukasa demonstrates his intellect and baits out two Gurongi. Yusuke recognizes Tsukasa transforming into Decade, the man who will defeat all the riders, and attacks him, but their battle is interrupted by Kick Hopper and Punch Hopper appearing due to a dimensional rift.

After the battle, Tsukasa goes off to a fight a revived N-Gamio-Zeda who is terrorizing the city by converting humans into Gurongi using his miasma. Yusuke saves Ai from the miasma, but is afraid to fight because she is dying. Her words are able to convince him otherwise, and Yusuke, along with Tsukasa, defeats Gamio. However, upon his return, Yusuke finds that Ai has died. Yusuke promises to go on fighting, in order to protect everyone else's smile.

But after visiting Ai's tombstone to pay his respects, Yusuke meets Kiva-la who brings him to Castle Doran in Kiva's World, where Yusuke offers his aid to the Fangire King Wataru before joining Tsukasa's group as a resident of Hikari Photo Studio.

However during the Rider War, though his world is destroyed, Yusuke still exists due to his traveling of the Nine Worlds. Even though he is destroyed by Decade in The Last Story, he and his world are restored, allowing him to aid in reviving Decade and defeating the newly formed Super Shocker once and for all.

World of Shinkenger
In the World of Shinkenger, Kuuga fought with Shinken Blue and Shinken Yellow of the Samurai Sentai Shinkenger to defeat the Kaijin Ride Eagle Undead of Chinomanako Diend.

Movie War 2010
Movie War 2010 currently remains the last on-screen appearance of Yusuke Onodera.

The Kuuga that appears in OOO, Den-O, All Riders: Let's Go Kamen Riders and Kamen Rider × Super Sentai: Super Hero Taisen is the original Kuuga, Yusuke Godai.

Personality and Abilities
Unlike Yusuke Godai who was confident of himself, Onodera was (initially) a rather meek and cowardly man who hesitated to fight the Gurongi. Although not as confident or courageous as the original Yusuke, this Yusuke also tries to protect everyone`s smile thus showing some resemblance. As he traveled with Tsukasa and the others, Onodera gained more confidence and became more mature as he was willing to sacrifice himself to save the Nine Worlds, showing much he changed compared to his initial appearance.

Also unlike the original Yusuke, this Yusuke wasn't very good at fighting and lost more battles than he won them. Even when he gained access to Rising Ultimate Form, this Yusuke wasn't able to control it for some time and lost most battles with it.

Kamen Rider Battride War
Although the playable Kuuga in Kamen Rider Battride War is confirmed to be Yusuke Godai, Yusuke Onodera makes an unofficial appearance in one mission and is directly referenced in another. In the mission Decade's Awakening, the first "boss" character fought is Kuuga, intended to represent Onodera (though there are no gameplay or vocal changes from the normal Godai version). Additionally, if the player uses Decade in the mission Kuuga's Awakening, Tsukasa will have special dialog where he acknowledges that Godai isn't the same man he traveled with, but says they both have the same desire to protect people's smiles and encourages Godai to remember that desire to help him break free of Mnemosyne. However, Kuuga cannot be used in Decade's Awakening due to the presence of the boss Kuuga, meaning Godai has no special dialog with Tsukasa.

Kamen Rider Battride War Genesis
Yusuke Onodera makes his playable debut in Battride War Genesis, with Ryota Murai reprising his role from Kamen Rider Decade. The primary difference between the two Kuugas is that Onodera lacks the powered-up Rising Forms, but instead, the charge attack is used to access Ultimate Kuuga (Black Eyes), which act as a limited form change. His strongest form is Rising Ultimate Kuuga (Red Eyes), and his Super Finishing Move is the Rising Ultimate Mighty Kick.

Forms
Just like the original Kamen Rider Kuuga, Kuuga can change into various forms into which he gains different powers and specialties. While he can transform into Rising Ultimate that Yusuke Godai did not access (until the 53rd/final episode of Kamen Rider Wizard), Onodera has not been seen using the Rising versions of his four basic forms. In the World of Agito, Yusuke dons the Kamen Rider G3-X (仮面ライダーG3-X) suit for a while. During the visit to the world of Den-O, Yusuke is possessed by Momotaros, who uses him as a body to transform into Kamen Rider Den-O Sword Form (仮面ライダー電王 ソードフォーム).

Equipment
Yusuke possesses some of the same equipment used within the original Kuuga, such as the Arcle (アークル) transformation belt, and a stone embedded in the belt called Amadam (アマダム) that serves as the source of his power and is able to extend a person's lifespan. He also possesses the TryChaser 2000 (トライチェイサー2000), a new model of police motorcycle designed to be faster and more powerful than the average bike.

Portrayal
Yusuke Onodera was portrayed by Ryouta Murai (村井 良大). As Kamen Rider Kuuga, his suit actors were Kenji Tominaga (富永 研司) and Norihito Itō (伊藤 教人). In Kamen Rider: Battride War, he was voiced by Nobunaga Shimazaki, who also voices his actual counterpart.

Etymology
Yusuke's surname Onodera (小野寺) is a reference to Kamen Rider Series creator Shotaro Ishinomori whose original family name is the same as Yusuke.
