I used a Ruthless Aggression Nunzio figure I had to make my own He-Man. I have the 200x version but none of the Matty-Collector ones yet (probably never will, as they're too expensive for me).
I used apoxie sculpt for the hair, some face touch-up, and belt disks. The belt itself is a rubber band. Apoxie was also used for his fur pants, boot cuffs, and boot straps.
