Candace

Candace Gertrude Flynn is the 15-year old sister of Phineas and Ferb, along with the eldest child of the Flynn-Fletcher household. She spends large portions of her time striving, but never succeeding to get her brothers in trouble for the things they do every day. While she isn't doing that, she would often be seen conversing on the phone, or hanging out with Stacy Hirano and less often Jenny Brown. She superficially possesses the behavior of a stereotypical teenage female.

Candace was born on the eleventh of July, fifteen years ago in Danville to Linda Flynn and an unnamed father. Her brother Phineas was born a few years later, this brought an end to the loneliness Candace had bore as a child. She has since come to share a varying, yet enduring relationship with her younger brother.

Candace lives a relatively comfortable life with her parents, her brothers, and their family pet. Her typical day consists of trying to get Phineas and Ferb grounded for what they do only to fail miserably. Having gone through the same routine dozens of times Candace has begun to behave in an erratic manner many would call insane. Her brothers occupy a large portion of her thoughts and their regular endeavors, although unintentionally, are a menace to her composure. Due to this it's difficult for her to relax and avoid thinking about them.

This habit has taken a reasonable toll on her life, leading her mother into questioning her sanity and forcing her close friends Stacy and Jenny to cope with her frequent obsessions over her brothers.

Her obsession with her long-term romantic interest, Jeremy also takes up large portions of her time. Candace would spend hours stalking him and watching his every step, particularly during his working shifts in Mr. Slushy locations across Danville. Along with that, she'd also strive to get his attention on numerous occasions with motives varying between getting him to notice her and diverting his attention away from any other girl who may have been flirting with him. These habits have since faded following the official start of their long-yearned romantic relationship during the the end of the Summer Solstice.
