Candace Flynn is a fictional character created by Dan Povenmire and Swampy Marsh for the animated television series Phineas and Ferb and is the deuteragonist of the show. Candace is voiced by Ashley Tisdale.
Every day of their summer vacation Candace’s brother Phineas Flynn and their stepbrother Ferb Fletcher build a new machine or invention. Candace knows that she would get in serious trouble with her parents if she did anything like create Phineas and Ferb’s inventions which she believes are dangerous so every day she tries to show her mother Linda what Phineas and Ferb created so that she’ll get angry and punish them (or as Candace puts it “bust them”.) But by the time Candace shows her mother Phineas and Ferb’s latest invention it has mysteriously disappeared (normally because of Perry the Platypus’s battles against Dr. Doofenshmirtz) making Candace look like she’s insane.
Candace appears in Milo Murphy’s Law in the crossover episode The Phineas and Ferb Effect, in which she argues that Phineas and Ferb shouldn’t include Milo Murphy in their plan to save the world because around him “everything that can go wrong will go wrong” only to change her mind about Milo after realizing just how resourceful he is.
Candace is the main protagonist of the Disney Plus original movie Phineas and Ferb the Movie: Candace Against the Universe.
