Disclaimer the lore might be too scary for some audiences you have been warned once upon a time there was a man, this man wanted nothing more than to be well regarded by his peers in the scientific community so he set out to make a big discovery to find out if there was such a place as hell, he went to an old abandoned butcher shop were tragedy had struck with a malfunction from a robot, the scientist made a pentagram and opened a ouji board attempting to summon anything and he did, he summoned (and accidently trapped) the new king of hell in the robots body this now possessed robot attacked the scientist scooped out his insides and crawled inside his body now he is a rotting corpse.
created by the devil as his most powerful minion ROT overthrew the devil knowing he was more powerful than him and attempted to escape hell to take over heaven but a scientist intervened and trapped him inside a robot now he roams the world looking for anyway to escape his robot body and return to his true form so he can finally take over heaven
