I would be meaning that if TDKR's Catwoman was the topic of discussion....you mean hands ON?![]()
However, Batman would fit in nicely in a contextual sense: in terms of being a scientific genius, Stark is more the innovator and inventor, and Batman is more the methodical investigator and theorist, so they would actually complement each other well (or conflict with each other even worse, which would be fun to read about or see in either case).
