In DC Comics' strange history, we have the character of Composite Superman:
Robot Chicken has a sketch where he shows up and there is an argument about his name:
Superman: Dear God, it's half a monster!
Batman: He's…he's some sort of—
Superman: —Composite Superman!
Batman: Composite Batman you bastard!
Superman: Not if I tell people first!
In the comics where he is introduced, why is he called "Composite Superman" and not "Composite Batman" if he's 50% of both?
