Daikengo

Daikengo is the titular robot of Uchu Majin Daikengo and is a super robot featured in Knights of the Multiverse Season 1. It was created by the evil organization L.O.S.R. to combat the powerful Raideen, with it being made in the image of a demon to counterbalance Raideen's appearance as a god.

Personality
To fit with it's demon-like appearance, Daikengo was programmed with the personality to match. He's completely monstrous in all of his actions, from battling with whatever dirty measures he feels like to attacking innocent civilians. In fact, the reason he decided to have his battle with Raideen take place in the center of a ruined city was just to tick him off.
