You may remember her from such films as "Attack of the Fifty Footed Woman" and "Swamp Thingy" from Steven Spielberg Presents Toonsylvania. The show was lost media for over a decade, and while the Spanish dub was found, the full English version still hasn't been found.
She doesn't have a name, as the segments she appears, "Attack of the Killer B-Movies", in are B movie parodies so she has a different name each time. Most commonly referred to as Professor Mann's (or Man) Daughter. Even the Professor's name isn't consistent.
Her design also varies slightly between segments, with her hair ranging from white to platinum blonde to golden blonde, and sometimes has a hairband. In at least 1 segment she has slightly more realistic proportions. But her lack of nose, blue eyes, red lips, hair covering one eye, and mole are consistent.
