- "Change us into the Majin King! Majin Fusion! Maagi Giruma Magi Jinga! MagiKing: Number One!"
- ―Combination announcement[src]
Majin Gattai MagiKing (マジキング Majin Gattai MajiKingu?, Majin Fusion MagiKing) is the combined form of Magired's MagiPhoenix form and the Magiranger's forms that make up the MagiDragon. The Majin perform this combination when they dial Maagi Giruma Magi Jinga (1-2-0-5) on their MagiPhones.
MagiKing wields the KingCalibur sword that is used in his Magical Climax finishers, "Magical Slash" and "Heavenly Magical Slash". For a brief time, Dark Magic Knight Wolzard sealed MagiKing's combination spell and took its power for his own, until FireKaiser destroyed the seal.
When GokaiOh and Gosei Great faced the Black Cross Colossus, the mecha of the first 33 Super Sentai, including MagiKing which possibly manifested from a toy version like DaiDenzin and the Variblune, appeared to back them up. When the Black Cross Colossus summoned several giant villains to oppose them, MagiKing fought alongside Gingaioh and Five Robo to destroy Hades God Dagon. After all the giant villains were destroyed, all 35 mecha weakened Black Cross Colossus with a combined attack before GokaiOh combined with the Variblune to become Goren GokaiOh which destroyed the Black Cross Colossus with the "Gokai Hurricane: Cassiopeia" finisher. With the battle won, the 33 past Super Sentai mecha vanished.
Through the powers of the Phantom Ranger Keys, the Gokaigers can re-create and summon the Greater Power of any Super Sentai team in existence. In Tokumei Sentai Go-Busters vs. Kaizoku Sentai Gokaiger: The Movie, the Phantom Ranger Keys reproduced the greater power of the Go-Busters, which allowed their respective mechas to transform to other previous Super Sentai mechas through Megazord keys. Masato and J on board Buster Hercules used their Megazord key to transform into Majin Gattai MagiKing.
