In "The Shaping Staff" the evil Faker seems to be largely a diversion for the episode, having nothing to do with the Shaping Staff itself. His appearance is so fleeting that it attains the notion of being an add-on or an afterthought. The concept of there being an evil He-Man is so interesting that we wonder why Filmation did not create an entire episode around the Faker character.
By combining the Skeletor and He-Man model sheets you can see below what the character may have looked like in the hands of Filmation. Below are two versions; on the left is Faker colored as the action figure; and on the right colored as he is pictured on the backs of the Mattel cards.

Faker; possibly one of the most wasted characters in the He-Man series.
