## South Park

Marshall joined *South Park* after the death of [Mary Kay Bergman](https://www.edgepedia.org/mary-kay-bergman), the show's original lead female voice actress, on November 11, 1999.<sup>[3](https://southpark.wiki.gg/wiki/Mona_Marshall)</sup> Sources differ slightly on her start date: IMDb describes her as voicing characters on the show since 1999,<sup>[1](https://www.imdb.com/name/nm0551065/)</sup> while the South Park Archives states she began voicing various characters in 2000.<sup>[3](https://southpark.wiki.gg/wiki/Mona_Marshall)</sup> A background history of the show records that Marshall and Eliza Schneider succeeded Bergman, with Schneider leaving after the show's seventh season (2003).<sup>[6](https://ttabvue.uspto.gov/ttabvue/ttabvue-92061245-CAN-93.pdf)</sup> The official character guide lists Marshall as the voice of Sheila Broflovski from season 8 to the present, with Bergman having voiced the character in seasons 1 through 3.<sup>[7](https://southpark.cc.com/w/index.php?title=Sheila_Broflovski)</sup>

Her credited *South Park* roles run to more than a hundred named parts, including Sheila Broflovski, Linda Stotch, Red McArthur, Henrietta Biggle, Wendy Testaburger (which she voiced from "Timmy 2000" until "Fourth Grade", before [April Stewart](https://www.edgepedia.org/april-stewart) took over), [Hillary Clinton](https://www.edgepedia.org/hillary-clinton), Bart Simpson, and Liane Cartman.<sup>[3](https://southpark.wiki.gg/wiki/Mona_Marshall)</sup><sup> • </sup><sup>[8](https://www.imdb.com/title/tt0121955/characters/nm0551065/)</sup> She has continued in the role into the show's later seasons and its specials, voicing Sheila, Linda Stotch, and Mrs. Tweak in the 2024 special *South Park: The End of Obesity*.<sup>[2](https://mn2s.com/booking-agency/talent-roster/mona-marshall/)</sup>

## Anime and dubbing work

Marshall credits much of her career to anime dubbing. Her first anime job came through an audition with director Wally Burr, playing a little girl on *Space Pirate Captain Harlock*; at the time she did not know what anime was, only that she was replacing Japanese voices with English.<sup>[9](https://otakuusamagazine.com/celebrating-pure-anime-love-mona-marshall/)</sup> She has since appeared in English dubs of *Digimon*, *Cowboy Bebop*, *Spirited Away*, *Naruto*, *Bleach*, *[Wolf's Rain](https://www.edgepedia.org/wolfs-rain)*, *Love Hina*, and *Blue Exorcist*, among others.<sup>[9](https://otakuusamagazine.com/celebrating-pure-anime-love-mona-marshall/)</sup><sup> • </sup><sup>[1](https://www.imdb.com/name/nm0551065/)</sup>

Two roles stand out. She voiced the tech genius Koushiro "Izzy" Izumi in the English dub of *Digimon Adventure* (1999), a part she reprised in the *Digimon Adventure tri.* films and *Digimon Adventure: Last Evolution Kizuna* (2020).<sup>[1](https://www.imdb.com/name/nm0551065/)</sup> She also voiced the title character in Bang Zoom's English dub of *Doraemon* (2005).<sup>[1](https://www.imdb.com/name/nm0551065/)</sup> Her film work includes additional voices in *Monsters, Inc.* and *Spirited Away* (both 2001) and *Frozen* (2013).<sup>[2](https://mn2s.com/booking-agency/talent-roster/mona-marshall/)</sup>

## Video games

MobyGames credits Marshall on 59 games, from early roles such as Musashi in *Brave Fencer Musashi* (1998) and Kite in the *.hack* series (2003–2004) to recent work including *South Park: The Stick of Truth* (2014), *South Park: The Fractured But Whole* (2017), *Fire Emblem: Three Houses* (2019), *[The Elder Scrolls: Blades](https://www.edgepedia.org/the-elder-scrolls-blades)* (2019), *[Avowed](https://www.edgepedia.org/avowed)* (2025), and the *Bravely Default: Flying Fairy* HD Remaster (2025).<sup>[5](https://www.mobygames.com/person/73313/mona-marshall/)</sup><sup> • </sup><sup>[2](https://mn2s.com/booking-agency/talent-roster/mona-marshall/)</sup>

## Career and method

Marshall came to California intending to be an on-camera actor and found voice acting instead. In her own account, voice work removed the limits of look, age, and sex that constrain on-camera performance; about half her career has been spent doing little boy voices, and she has also voiced old men, a male lizard, and a male raven.<sup>[4](https://monamarshallblog.wordpress.com/2017/09/05/finding-fortune/)</sup> She attributes her dubbing skill to two backgrounds: training as a singer and songwriter, which helped with timing, and years of hand-puppet performances on tour with The LA Moving Van And Puppet Company, which taught her to keep voice and movement in sync.<sup>[9](https://otakuusamagazine.com/celebrating-pure-anime-love-mona-marshall/)</sup>

Her entry into the field came through [Daws Butler](https://www.edgepedia.org/daws-butler), the original voice of [Yogi Bear](https://www.edgepedia.org/yogi-bear), Quick Draw McGraw, and [Cap'n Crunch](https://www.edgepedia.org/capn-crunch), whom she studied with as a voiceover mentor; her first industry job was a radio audition he directed, a Sherlock Holmes adaptation in which she won the part of a maid requiring a Scottish accent.<sup>[2](https://mn2s.com/booking-agency/talent-roster/mona-marshall/)</sup><sup> • </sup><sup>[10](https://digipedia.db-destiny.net/cast_crew/marshall.htm)</sup> Early credits include guest shots on *The Smurfs* after she approached Hanna-Barbera directors directly, and work dating back to films such as *Starchaser: The Legend of Orin* (1985) and *Rainbow Brite and the Star Stealer* (1985).<sup>[9](https://otakuusamagazine.com/celebrating-pure-anime-love-mona-marshall/)</sup><sup> • </sup><sup>[11](https://www.rottentomatoes.com/celebrity/mona_marshall)</sup>
