Thoughts?

Horrible.

Thoughts?
Crap.

Shit list, you either go by how iconic the character is, or how good it is as a character, when I saw the number 1 spot I facepalmed slowly, and kept my hand on my face for over 20 seconds because that pick is just so stupid.

Oh, and number 1 spot should be Bobby Kotik.

Horrible just like IGN.

I knew it wpuld end like that, but at least it's unexpected
also shame no pokey on the list

Yea I've never even heard of the #1 spot >_

I know Bowser is a recognizable villain. But that doesn't mean he is a good one.

Seriously, how many times do you capture the same princess only to get your ass kicked by a plumber.

...and Mike Tyson being on there is just....DUMB.

Because you never played the game.

It's an awesome and a hilarious villian, yes. But it's definitely not the best.
