Why didn't you do Two-Face? Plus, If you do the mandarin, he counts as either Slattery or Killian, depending on if you want to do the real one or the TV one. You shouldn't do all 3.
Mate, you missed out so many villains, a hero gone bad is by definition a villain. Not to mention the villains from Captain America 1 and I'm sorry, Zsasz is a name drop, not a villain, if you're putting Zsasz in but not Two-Face and Catwoman ... rethink the quiz and come back maybe?
