May seem like a mismatch but let’s see
The villan known as Killer Croc
Vs
The soldier Captian Atom
Who wins? Why?
Captain Atom. Why? He goes the big boom.
Croc might get a hit in just because Captain Atom would be completely bewildered that he’s even making the effort. It wouldn’t do anything, but a hit would be gotten.
Captain Atom. He’ll hit him with an atomic blast while flying to be out of Croc’s reach.
