The Cult of Galvatron once hunted Sweeps, and sought to kill Megatron and use his energy to revive Galvatron. In December of 2014, "Galvatron" mysteriously returned from the dead on his own, and appeared to kill "Megatron" in front of a large group of his followers in Kalis. After destroying two cities, "Galvatron" was killed by Megatron, and the cult that had formed around him wiped out by a team of Decepticons.
