At one point Donald got on my nerves because I couldn't understand what he was saying half the time and he has a crappy personality, but Donald is an unoriginal answer, I gotta think about it more...
Frollo. The guy is such a douchebag and completely unlikeable. A character that I Любовь to hate. Sarousch was a hell of a lot еще likeable and was funny too.
If Дисней Channel, Дисней XD, или Дисней Junior characters count, then, I say соленый огурец, маринованные and арахис from the Дисней XD show, "Pickle and Peanut" are the most annoying characters Дисней has ever created, if Walt Дисней was still alive, I think he would be horrified if he saw this show.
