Kamen Rider Gaim: Final Stage
Entering into the world of the dead, Maja introduced himself to the Armored Riders and Over Lords as a "snake". Maja promptly converts all of the Riders and Overlords into his servants to assist him in taking over the world. Kamen Rider Gaim Kiwami Arms then appears to stop him, but Maja and his dead Riders easily defeat Gaim. Maja then steals Gaim's power and sends his Rider servants into the world of the living.

Maja later confronts the Armored Riders, who had their Sengoku Drivers restored by DJ Sagara, after they find Kouta and discover he has lost his memories. Transforming into Kamen Rider Gaim Yami, Maja summons the resurrected Riders to fight the Armored Riders. Maja then attempts to kill Gaim, but he is stopped by Takatora and Mitsuzane Kureshima, who give Gaim the Orange Lockseed and allow him to assume his basic form.

Maja eventually appears again to attack the Riders, summoning Demushu and Redyue to take on Gridon and Bravo while he fights Ryugen and Zangetsu. Maja initially overpowers the Riders until Gaim appears and receives the Lemon Energy Lockseed from Takatora, allowing him to transform into Jimber Lemon Arms. Despite the power of Jimber Lemon Arms, Gaim is still beat down by Maja. However, Kaito then appears and reveals that he was only pretending to be under Maja's control. Maja attempts to incapacitate Kaito with Helheim vines, but Kaito latter breaks free and transforms into Lemon Energy Arms. Kouta somehow still doesn't remember who Kaito is. Kaito is soon joined by Kouta after he transforms with Kachidoki Arms. Maja then summons Dyudyuonshu, Shinmugurun and Grinsha to attack Kaito and Kouta, but the two easily defeat them. Kaito then grabs Maja as Kouta reobtains the Kiwami Lockseed and shoots at Maja.

Maja then transforms from Gaim-Yami into Kamen Rider Maja. However, Kouta transforms into Kiwami Arms and is joined by all of the Armored Riders. Maja calls upon all of the Over Lords once again and a final battle commences between the Armored Riders and the Over Lords. Maja is finally defeated by Gaim, who strikes him down with Rosyuo's sword.
