Who: Loki

What: Convincing Norman Osborn to wipe out Asgard

When: April 2010

Where: Siege: Loki #1

Why it's a great moment: We all know Loki screws with people. That's his thing. But sometimes he really does it with panache. Look at that guy! He is so pleased with himself. And here's the thing: You know why he's doing it? He's tired of being Loki. Not because he hates screwing with people (he clearly loves it), but because he hates that everyone in Asgard is stuck in such rigid roles. So he's just gonna wipe that whole scene out.

But not before guaranteeing his immortality and arranging himself a nice little summer home in hell. It doesn't end up working out for him, but you have to admire the guy for his style.
