Joan "Joanie" Bovein is the 6th adopted daughter of Mike Bovein, and the sister of Janet, Bru, Marsha, Avril, Mayflower, Augusta, Amber, Tobi, Nova, Dodecahedron, Julia Bovein, and Camilla Wight-Bovein. Joanie is a rotten, money-grubbing bitch who will do whatever she can to make a buck.

She is also a lesbian who is attracted to busty women. It is speculated that many of the naughty photos that appeared around Leonardo High School of Joanie's sister, Julia, where taken by Joanie herself, in exchange for money from the students to which the photos were distributed.

Joanie was the photographer for Leonardo High's school newspaper, which was edited by Ann Wang.

The Bovein family is a parody of M. Bison and the Shadowloo Dolls in Capcom's Street Fighter Alpha series. Julia and Joanie are direct parodies of Juli and Juni.
