Shun Kageyama

Shun Kageyama (影山 瞬) was Kamen Rider PunchHopper (仮面ライダーパンチホッパー). He was also the third and primary user of Kamen Rider TheBee (仮面ライダーザビー).

Kamen Rider Kabuto
He, 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 "Perfect Harmony" (完全調和). 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 favor 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 to 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 eventually goes insane and wants to kill Daigo in order to become TheBee once again. The ZectTroopers try stop Kageyama, but he (Kageyama) does not care about him betraying ZECT and only wants to become TheBee. He eventually stops attempting to kill Daigo, but The ZectTroopers are about to kill Kageyama until he 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" (Brother or boss).

Once their partnership formed, both Kageyama and Yaguruma set out 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 KickHopper 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.

Kageyama works with Yaguruma in an attempt to destroy a confused and weakened Rena Mamiya during episode 40, in hopes of eliminating her early. Their attempt almost works, but Rena is saved by Kamen Rider Drake along with Gon, who distracts them, allowing their party to escape. Their plan did have a side effect however, resulting in a recovery of Rena's Worm memories. Kageyama later asks Yaguruma why he didn't kill her, and an extremely happy Yaguruma answers by saying that he has indeed taken a liking to her. Even more so, Yaguruma protects Rena from Subst Worm when she is endangered. This led to an infuriated Kageyama, as it went against their beliefs of abandoning the light. Yaguruma is shocked however, when he gets rejected by a temporary Uca Worm, and his bond with Kageyama is restored.

During episode 41, Kageyama and Yaguruma defeated Tsurugi, and through depressed, Tsurugi is tricked into joining them. The trio then eventually encounters Reiji Nogi who makes short work of them using "reflect" to use all their Rider Finishers against them. Kageyama and Yaguruma watch as Reiji Nogi advances on Area Z during episode 44, and Kageyama wants to help them fight, but Yaguruma laughs at him for trying to be an ally of justice. Kageyama reverts to his old self briefly and picks up the abandoned TheBee Brace, until after being defeated by Reiji Nogi. Ultimately, he returns to his old style and becomes PunchHopper again. Kageyama also follows Yaguruma's way of regaining the darkness by binding himself with chains. He ignores Tendou's request for help, stating that he will not help humans. Along with PunchHopper, KickHopper defeats Cassis Worm Clipeus in episode 46. The two Hoppers utilize the Rider Jump function to send Cassis Worm flying into the air, destroying him with a Rider Kick and Punch as he falls down.

Kageyama later becomes one of the many looking for the Worm identification necklaces, believing them to be useful in his mission. Upon seeing Kageyama with a Worm identification necklace, Tendou warned Kageyama about the side effects of the necklaces but failed. In episode 48, Kageyama tells Yaguruma that he has become a Native and can no longer control himself due to fact that having three Native necklaces sped up his transformation. As a show of pity, Yaguruma used a Rider Kick to end Kageyama's suffering. As Kageyama dies in Yaguruma's arms, Yaguruma mentions that after all they've gone through, the two will always be partners. They will look to the light for a new future.
