2. Mido (The Legend of Zelda: Ocarina of Time)
Let's face it, I could simply ask you to look at the picture above and leave it at that. Just look at what that little shit is saying to you (and for no reason, might I add). The Ocarina of Time is one of the most beloved games of all time and the main villain in the game, Ganondorf, is a Grade A jerk, no doubt. However, at least he has an evil plan to execute and wanting to take over the world tends to lead to a certain amount of douchebaggery. Mido, on the other hand, is just a dick for being a dick's sake. He constantly mocks the player and will not allow Link to pass through until certain criteria are met. If I'm 100% truthful, I found that getting past Mido and seeing that smug look on his face dissolve was actually more satisfying than defeating Ganondorf. If Nintendo ever release a Legend of Zelda game where Mido is the main antagonist, I'd buy that in an instant, just to get a chance to kill him.
