In the final stages of the film, she deserts Skeletor after he absorbs the power of the universe without sharing it with her. This remains consistent with the various portrayals of the character as scheming and willing to turn on Skeletor from the mini-comics, Filmation series, and 2002 series. Evil-Lyn is not depicted as a powerful magic-wielder in the film (although it is not stated that she does not have such powers either) and does not carry her distinctive orb-staff. In the film, she rarely uses magic, although in one scene she casts an illusion to make herself appear to be the dead mother of Julie and also uses her powers to keep the door of the music store closed while Julie brings her the Cosmic Key. Describing her character, Foster said that Evil-Lyn is not villainous, "she is just doing her job and she knows how to get results, even if it means being harsh." Langella agreed, calling Evil-Lyn a female more dedicated to Skeletor's cause than any man; she is obsessive around Skeletor because she is slightly lovelorn. The filmmakers considered having Foster wear eye-lenses to mask her naturally pale-blue eyes, but decided that her natural eyes fit the character better. However, they did augment Foster's chest, fitting cleavage into the character's costume. Foster wanted the character to have a large hairstyle, rather than the short style featured in the film.
