Eldran

Eldran is a patron saint of Earth who remodels the school into a robot in Raijin-Oh and Go-Saurer and the town into a robot in Ganbaruger, without permission, entrusting children with Earth's fate. His original enemy is the devildom in Ganbaruger; the appearances of the Jaaku Empire in Raijin-Oh and the Mechanization Empire in Go-Saurer were unexpected to him.
