is one of the main anti-heroes of the 2006 Kamen Rider Series Kamen Rider Kabuto.

, for most of the series, operated as Kamen Rider TheBee, acquiring the TheBee Zecter after Kagami relinquished it. Prior to it, Kageyama was originally under Yaguruma's command and a good friend of his, believing deeply in his superior's philosophy of teamwork and . After TheBee Zecter rejected Yaguruma and chose Kagami, Kageyama attempted to make Kagami understand his new responsibilities. He was baffled when Kagami rejected TheBee Zecter in favour of his friendship with Tendou, whom he developed a grudge against.

Becoming the new leader of Shadow, Kageyama turned his back on Yaguruma and used many methods that contradict his former mentor's beliefs of "Perfect Harmony", Tendou saw Kageyama unfit to be a leader. Overtime, Mishima also sees Kageyama as being unable handle the missions assigned to him. Eventually, Kageyama is defeated by a vengeful Yaguruma who relieved him of the TheBee Zecter which ended up in Tendou's possession. No longer qualified as TheBee, Kageyama was ousted from the Shadow elite and cast into humiliation and shame. Battered and broken in both body and mind after being facially scarred in the crossfire between Shadow and the Worms, Kageyama is saved by Yaguruma, who once again invites Kageyama to hell, this time giving him his own Hopper Zecter as a present which allows him to transform into Kamen Rider PunchHopper. Now under Yaguruma's wing, he refers to him as "aniki" (Bro or boss). As either TheBee or PunchHopper, Kageyama uses a fighting style themed around punching attacks.

Once their partnership formed, both Kageyama and Yaguruma set out to for revenge against Kabuto by ambushing him and Gatack within an abandoned factory. Kick and PunchHopper demonstrate their new abilities, easily defeating Kabuto and Gatack in a matter of minutes after the two were weakened by the activation of the 'Red Shoes' system. Unlike Yaguruma, Kageyama is not completely into the darkness yet and Yaguruma often corrects his way of thinking whenever Kageyama shows signs of 'reaching the light'. This is first shown when he tries to grab onto a bit of light after meeting a young girl who he defends from Leptophyes Worm. Yaguruma tells him that his way of thinking is wrong and even the slightest bit of light will destroy them. After discovering the girl Kageyama saved early had become a Worm, PunchHopper along with Kick Hopper annihilate the Worms together, and they manifest in their own power. Kageyama once again questions the value of the light, but Yaguruma tells him that they live in a world of darkness, and that he should not seek the light.

Kamen Rider PunchHopper has not been a contender in any CBUB matches.
