Lorraine

Lorraine is Betty Jo Flynn's identical twin sister. She comes to Betty Jo and Clyde Flynn's and comes out once a year to play pranks. The rest of the time she "stays in a closet". She is Candace, Phineas, and Ferb's great aunt, and Linda Flynn-Fletcher and Tiana Webber's aunt. She is also Clyde's sister-in-law.

She has the same shade of red hair as her sister and Candace.
