Candace Flynn

Candace Flynn is Phineas and Ferb's teenage sister and one of the characters in The FT Squad's Adventures With Phineas and Ferb. Candace is aware of the incredible inventions her brothers create throughout the summer, but she does not approve of them. She often times tries to bust them by showing their mother the inventions and ideas, but most of the time it fails. There have been some cases however, where Candace actually joins Phineas and Ferb on their adventures, either for the sake of doing something that can help her, or to have fun. Despite her irritation, she cares for the welfare and safety of her brothers.
