10 Villains Superman Has NEVER Defeated

After reappearing in DC comics in 2013, Killer Frost has become kind of a big deal. Not because she's in a lot of comics, because frankly some background characters without names have been in more issues in their time.

No, Caitlin Snow is a big deal because she's now an absolute powerhouse when it comes to her frosty abilities. The usual cliched ice powers Killer Frost has have been bumped up to eleven, and she's possibly the strongest wielder of ice in the DC universe aside from gods.

This means that when she fights Superman in a confrontation between the Justice League and the Suicide Squad, things don't totally go according to plan. Frost absorbs Superman's heat - and thus his "life force" - the second she gets near to him, which knocks the hero out for the rest of the fight.

Though Caitlin's intentions were to kill him, she actually just puts him in a hibernation for a while, and our favourite golden boy is all well and sound by the end of the big fight. But it's still pretty impressive work from a character you would have initially just considered yet another cold-based criminal. Mr. Freeze can only dream.
