Suzy Johnson is a recurring antagonist of Phineas and Ferb. She is the little sister of Jeremy Johnson. She has a high-pitched squeaky voice and appears very cute, innocent and beautiful. Despite her cuteness and beauty, she is actually very manipulative and spoiled. She always has to get her own way and will do anything to keep Candace away from her brother. Due to comments given by Buford Van Stomm to Phineas and Isabella, it can be assumed she terrorizes them as well.
