Real Name: Evelyn Morgan Powers
Raised by her father in the ruins of Zalesia™, Evelyn left her home in a fit of teenage rebellion. Taking the name Evil-lyn®, she traveled Eternia® learning from many of its great masters the ways of magic and the dark arts. While searching for new ways to increase her power, she met and met and fell in love with an ambitious alchemist named Keldor™ and agreed to join his cause. After Keldor™ was transformed into Skeletor®, he lost all emotional attachments to Evil-lyn® and she began to scheme against him. In a series of miscalculations, she helped release both King Hssss™ and Hordak™ from their inter-dimensional prisons. Evil-lyn® uses her crystal ball to foresee the evil future!

Fans over on He-Man.org are already deep in debate over this bio. The target of most of the ridicule is her name; for what it’s worth, it is derived from the original He-Man Bible, though that’s hardly a good source for names–if it were, Skeletor’s #1 punching bag would have been “Biff Beastman,” which makes Raqquill Rqazz sound like Horatio Alger.

As for the rest of the bio, there’s some complaints here and there, particularly because Evil-lyn is responsible for unleashing both King Hssss and Hordak due to “a series of miscalculations” (making her look like a bit incompetent), though I think that was actually what happened in the 2002 cartoon.

There are also some complaints about how the figure looks too toy-ish, which is entirely due to the Bright Molded Plastic Factor (BMPF) (see also).
