Here is another illustration from one of the many Masters of the Universe coloring and activity books, and another example of the artist paying close attention to the Filmation series. Yes, the pose of Evil-Lyn is pretty much lifted from her model sheet pose, but the Teela one is new. However, I have to question the size of Teela's legs. Yes, athletic females do have strong legs, but in this illustration it appears that she has borrowed He-Man's legs!
