First appearance: Thor
Year: 2011
Looks like: Some sort of S&M fetishist.

The hammer-wielding god of thunder's costume could have gone very wrong. Thor barely wears his his winged cap in the movie adaptation, but that's ok. It might have looked cool in the comic book, but it doesn't really translate well in real life. Plus it had no practical use. Everything else makes him look like a badass futuristic Viking warrior prince from the future.
