Lord Yomi from Babel II. The story starts off as a fairly simple "boy discovers fated destiny" style, where he becomes a mighty warrior, powerful psychic, gets three invincible servants and a supercomputer in a secret base as an advisor. He meets his rival, discovers his plots and foils them. The series continued on further than the originally planned story was to go for however, and shifts more often into the villains perspective as he uses his wits and political control to attempt to defeat an established near-immortal hero. No wonder Giant Robo cast Babel II as the villain.
