Candace Flynn is the 15-year old sister of Phineas and Ferb and is considered to be the main antagonist of the series, although she also can be shown as the anti-hero of the series, too. Her day usually consists of attempting to get her brother and stepbrother in trouble with her mother, Linda Flynn, but by the time she arrives to see what they are doing, they always look perfectly innocent and normal. She is usually seen talking on her cell phone to Stacy Hirano, or less often Jenny and acts much like a stereotypical teenager when not trying to stop her brothers' antics.
