Death

Eventually GaoKing's components came back to life in the final battle.

Gokaiger
When GokaiOh and Gosei Great faced the Black Cross Colossus, the mecha of the first 33 Super Sentai, including GaoKing 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, GaoKing fought alongside Ohranger Robo and ChangeRobo to destroy Buredoran of the Chupacabra. 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.

Ranger Key
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. Ryuji and Yoko used their Megazord key to transform Go-Buster Lioh into Hyakujuu Gattai GaoKing.
