At the Six Flags in Chicago, Illinois (I go there often) a while into the line of Superman, The Ultimate Flight, they have boards that show each superhero and villian and their hieght weight,and eyecolor etc... in the Superman series and the board for Doomsday says he killed Superman and he's 7'3' or something.
Btw, Batman isn't really a "superhero", he has no "super powers" just gadgets.
