Faust attended the California Institute of Arts from 1992 to 1994. She started working in the animation industry as a character layouts artist for the character Julie from the MTV animated television series The Maxx, before becoming an animator at Turner Feature Animation and Warner Bros Feature Animation, where she worked as an animator on feature films such as Cats Don't Dance, Quest for Camelot, and The Iron Giant.
Faust shifted to television animation in 1999, working on The Powerpuff Girls and Foster's Home for Imaginary Friends[4] at Cartoon Network Studios as a storyboard artist, screenwriter, supervising producer, story supervisor.[5] Faust created and developed the toy line Milky Way and the Galaxy Girls.
Faust worked with Warner Bros. in 2019 to develop a reboot of DC Super Hero Girls. As of 2021, she was developing an animated series for Netflix Animation, called Toil & Trouble. However, the series was cancelled by August of that year due to a change in leadership. Faust mentioned in April 2022 that she managed to retain the rights to the show, and was hoping some other network would pick it up eventually.[9][10][11][12][13]
In 2011, Faust offered to design new characters for the fangame My Little Pony: Fighting is Magic after a cease and desist from Hasbro. The new characters became the basis for Them's Fightin' Herds, which was successfully funded on Indiegogo and was released to Early Access on Steam in 2018.[14][15] The game left Early Access in 2020, when the first chapter of story mode was released. In November 2023, it was announced that after the completion and release of in-development DLC playable fighters, active development of the game would cease, including the rest story mode, of which the entire plot outline had already been written.[16] Faust herself expressed disappointment at this news, wondering if perhaps a "show or a comic" could be made out of the existing story that had already been written.[17]
Faust is married to Craig McCracken, creator of The Powerpuff Girls, Foster's Home for Imaginary Friends, and Wander Over Yonder.[3] They met while they were working on the third season of The Powerpuff Girls.[18] Faust has worked with her husband on all of his shows. She considers herself a lifelong feminist.[19] Faust took maternity leave in mid-2016 to take care of her newborn daughter.[20]
