The catboy Schrödinger is one of the members of the Millennium elite, a modern-day group of Nazis. He holds the power to appear "everywhere and nowhere" (his name being a direct reference to Erwin Schrödinger and his thought experiment "Schrödinger's cat"), as well as being able to regenerate fatal wounds. His combat abilities and motives are currently unknown, though Hirano has confirmed he is a creation of Doc.
