Trixie Tang is a big-time troublemaker who was created from the same character from the show "The Fairly OddParents". She was originally created by ElmoRockStar2002 and Muma X992, then was reborn as a troublemaker by SquadHater2002. Her first appearance as a troublemaker was in SquadHater2002's "Cussing in Class" video. You can view the video here: []
The Fairly Odd Parents Wiki refers to Trixie Tang as an 11-year old Asian-American. According to ElmoRockStar2002, Trixie's voice is Julie.
Her appearance was fixed to look more like the FOP Trixie Tang in the video "Trixie and Veronica hit on Starfire/Grounded".
