Hans is so funny and I'm dying to know what happened in Denmark!

I don't really care for Officer X, and we don't really know too much about the Red Squirrel or Savio. Hans was really cool, but I don't think he was necessarily evil. Dr. Blowhole, on the other hand, is pure take-over-the-world-and-destroy-my-enemies evil, and he was the penguins first main enemy ever showed. Plus, he's a dolphin with a mechanical eye! How cool is that? :D

Blowhole, by far.

@Kinkystar: I am dying to know that, too! By the way, you forgot Clemson and the Vesuvius twins.

Blwohole. He's epic and cool. He's a pretty good singer too. Also, he's eeevvviillll.

Dr. Blowhole is epically awesome!!!!!! You know in an epic kind of way.
