|I'll swoop your leg, sucka!|
Created in 1966 by a then-13-year-old Jim Shooter for the Legion of Superheroes, Val Armorr of Earth is a master of every form of martial art that will be invented by the 31st century. In his initial appearance, he convinces the Legion of Superheroes to allow him onto their team when he uses his "super-karate" to beat up on Superboy. Despite that impressive feat, he's pretty far from my favorite member of the Legion, and I think he unofficially holds the record of having been killed off the most times. Some writers (Keith Giffen) just hate this guy.
Although the movie character has almost nothing to do with Val here, if you watch there is a prominent credit thanking DC comics for the use of their character's name. So now you know.
