Who's your least favorite character so far?

Ah yes my least favorite character hands down is definitely Nom-Nom. He may seem like a cute innocent little Koala bear, but deep down he only truly cares about himself and his career. He can care less about the bears, and in one of the episodes he even was putting Panda and Grizz in danger just for his own fame. >_> I also find Charlie to be a bit annoying as well too, but I can see why he acts the way he does. (He's still somewhat annoying though... xD)
