YMMV / Batman The Brave And The Bold S 2 E 9 The Super Batman Of Planet X

• Magnificent Bastard: Xel Rohtul, the alternate version of Lex Luthor himself, is a maniacal Evil Genius who seeks to destroy the Zur En Arrh Batman and take over Gothtropolis. Laying siege to Gothtropolis with his robot army, Rohtul is only beaten when the Batman from Earth arrives and gain superpowers. Allowing himself to be captured for time to devise a new plan, Rohtul uses a tooth-embedded device to activate his backup robot army that frees him from prison. Rohtul then reveals he deduced the source of Batman's powers and his weaknesses as well, utilising Quartz in all of his robots to weaken and nearly destroy both the Batman from Earth and Zur En Arrh in one fell swoop.
