Anita emerges as a supporting character from the *Darkstalkers* video game series, first appearing non-playable in *Vampire Hunter 2: Darkstalkers' Revenge* (1995). She is portrayed as a young human girl, an orphan rescued by the dhampir warrior Donovan Baine, who becomes her guardian as he pursues freedom from his own vampiric curse.

Her role later expanded beyond support, becoming a playable fighter unlockable via code in *Marvel Super Heroes* and featuring as a secret character in *Super Puzzle Fighter II Turbo*. Her most notable evolution occurred in the Japan-exclusive *Darkstalkers Collection* for PlayStation 2. Within the ending narrative for "Dee" – an alternate Donovan embracing his vampiric nature – an aged Anita is revealed possessing inhuman powers and destined to rule humankind.

In the *Night Warriors: Darkstalkers' Revenge* OVA, Anita remains Donovan's companion, functioning solely within his storyline and reflecting their established game dynamic without receiving additional backstory or independent development.
