Origin #1 (Filmation):
With her intelligence, fearlessness and her incredible magic skills, Skeletor clearly could not hope for a more capable ally than Evil-Lyn, who is often left in charge when he is away from Snake Mountain. Although the toy line may have designed her as an evil counterpart to Teela, in the cartoon she was really more of an evil counterpart to the Sorceress, rather than Teela, seeing as how she possessed no warrior skills whatsoever, but more than compensated for this by her expertise in magic and witchcraft.
Evil-Lyn is a master of disguiseand duped many people with her magical disguises in episodes such as "The Shaping Staff", "The Curse of the Spellstone", "Evil-Lyn's Plot" and "The Royal Cousin".
She is also shown to frequently branch out on her own and conduct her own schemes away from Skeletor in episodes such as Ordeal in the Darklands. "Journey to Stone City" and "No Job Too Small" also portray her working as an independent agent. Additionally, Evil-Lyn renders her services to aid other super villains, such as Gorgon in "The Defection", and Dark Dream in "Eternal Darkness", hence affirming time and again that she is by no means devoted to Skeletor.
Evil-Lyn is seen without her helmet for the first time in "The Witch and the Warrior" This is brought to the forefront in the episode, perhaps the most in-depth character study of Evil-Lyn in the series, in which she is forced into making an uneasy alliance with Teela, when the two of them are stranded in the desert together. Having always held Teela in total contempt, and never having regarded her as a formidable adversary (unlike He-Man and the Sorceress), Evil-Lyn acquires a degree of respect for the young warriors's skills and intelligence, going so far as to say that she and Teela could "make a great team" after all. She also declares to Teela in this episode that she has "no loyalty to Skeletor", and that she only works for him because she eventually hopes to acquire his superior powers. At the end of the episode, Evil-Lyn evinces shades of goodness as she thanks Mallek saving her life and healing her injuries. As a token of her heartfelt gratitude, she refuses to steal that which Skeletor sent her to obtain, and proves that she is not subservient like the other Evil Warriors, stating that Skeletor can "come get" what he wanted "himself"
Origin #2 (Mini-Comics):
Evil-Lyn only appears in six minicomics. She has yellow skin and is shown to be treacherous and deceiving. She even leaves Skeletor and tries to join forces with Hordak.
Origin #3 (1987 Live-Action Movie):
Evil-Lyn is shown as Skeletor's main sidekick as in the cartoon, although the film adds an extra dimension to her relationship with Skeletor by indicating a love interest between the two. In one scene, Skeletor indicates that he depends upon Evil-Lyn to portray the image of him as ruler to the people of Eternia. While sharing the desire for power between them, Evil-Lyn's calm and seductive approach is shown to soothe Skeletor's wrath and mania in his moments of hysteria.
After Skeletor punishes his minions for failure, Evil-Lyn attempts to speak on their behalf. This stance prompts Skeletor to force her into control of his troops on their second mission to Earth to track down the heroes. She succeeds in capturing the Cosmic Key, but Skeletor again disregards her when she reports that she has failed to deal with He-Man.
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.
Kevin Corrigan, a human teenager, describes Evil-Lyn's eyes as "strange" during the film. Although no explanation for this is given on screen, Evil-Lyn does not even blink her eyes at the bright light cast from Skeletor's transformation. All of the other characters present, including He-Man, cover their eyes or turn away
Origin #4 (MYP 200X Series):
for the 2002 relaunch of the Masters of the Universe toy line and cartoon series. While her portrayal in the new show is very much in-keeping with the original series, her background is expanded upon in the new series. She is revealed to be the daughter of a mysterious sorcerer known only as "the Faceless One", who lives in isolation amongst the ruins of Zalesia and is the guardian of a precious object called the Ram Stone. The Faceless One disapproves of his daughter's servitude of the evil forces and hopes that someday she will learn the error of her ways. The episode Lessons indicates that she still feels a familial bond with her father when she returns the Ram Stone to him after it was used by Skeletor in an attempt to breach Castle Grayskull. This further maker the counterpart to Teela, as their parents have similar roles.
The show's second season expands considerably on the theme of her disloyalty to Skeletor, as well as showcasing her origins. Unbeknownst to Skeletor, Evil-Lyn forms a secret alliance with Kobra Khan to free King Hiss and the Snake Men, whom she believes will grant her greater power than Skeletor. After the release of the Snake Men, Skeletor seeks to punish her by banishing her to the Forsaken Realm in the episode "The Price of Deceit". This episode features a flashback to the time she first met Skeletor, when he was still in the form of Keldor. The young Evil-Lyn had managed to impress Keldor with her great knowledge and power, had fallen in love with him and played a part in saving his life. After his injury at the hands of King Randor, she had taken him to the altar of Hordak, who gave him new life by turning him into Skeletor. After the transformation, Skeletor became more and more twisted and evil, ceasing the love between him and Evil-Lyn and inspiring Evil Lyn to overcome him rather than work alongside him . This episode also indicates there are sparks of good left within her as she considers defecting to the side of good after He-Man saves her life following a call for help from her father. Cute Later, in the episode "The Power of Grayskull" Evil-Lyn learns that Skeletor promised to free Hordak from the dimension of Despondos in return for having his life saved, but chose instead to destroy his sanctuary, knowing that Hordak could easily destroy him. She therefore chooses to free Hordak by herself in order to gain the power that she needs, and once again concocts a scheme behind Skeletor's back, allying with Count Marzo in the episode "History" to free Hordak from Despondos. Failing in her scheme, she vows to continue until she has freed Hordak. This plot was going to be expanded upon in the show's third season, but the cartoon was cancelled before any further episodes could be produced.
