Kim Possible: Antagonist

Antagonist: Enemy, Adversary, Rival, Competitor. Those were the first words to come to Kim's mind whenever she thought about Bonnie Rockwaller. Bonnie has hated Kim since they were little and why? Kim had no idea. Now Bonnie was even more of a bitch to Kim and despite everyone's protests that it was typical Bonnie behavior, Kim knew different. Something was wrong with Bonnie.
