The season one She-Ra episode "Troll's Dream" is one of the most memorable of the series. Aside from featuring an impressively immense premise in which The Evil Horde unleash the Spider of Crystal, the story also includes a sub-plot about racism, the return of the Trolls of Spikeheart, and a new villain, Duke Drear. I have always been a fan of the design of this character, especially the posture of his body; something that was transferred into the final episode. However, the color scheme left a lot to be desired, appearing to look like an extra from the awful season two He-Man episode "Time Doesn't Fly", which is why you are looking at a black and white model sheet, and not a color one!
