Ok first name your favourite character.
Then name the one you hate the most.
Swap all their powers, skills and abilities...do you still like them?
Is it the character you like or their powers, honestly?
Before anyone says anything about incompatibility, almost every character has been good, evil, underpowered and overpowered (when Batman got Superman's abilities).
And no lying by choosing characters other than the ones required, I am sure there are enough regulars around to point out the fibbers.
