I can't really "hate" anyone because the actors and actresses behind the characters are doing such an impressive and persuasive job of making us dislike certain characters. With that in mind, the person I love to hate is Scratch. That girl is crazy, and not in a good or cool way. She is definitely a type of villain that listeners can rally against. Gatekeeper was a character that I didn't like either, but again, it was the character's personality and demeanor, which is all due to KC's writing and Mark Miller's acting.
