Who was the robot on the Justice league show, that Lex teamed up with. And the robot learned all the justices leagues powers and beat them. Then flew off in space to learn more? I think he was pretty bad ass and if he came back, he would be the most powerful character ever.
I have no idea if the character was from the comics or created just for the show, but I can give you USELESS TRIVIA!! He was voiced by Robert Picardo who's most famous role was the Doctor on Star Trek: Voyager. Why did I bring that up? No idea.
I thought it was an interesting idea for a character, although it made absolutely no sense.
