3. Beast Man
Beast Man is Skeletor's right hand man in nearly every version of Masters of the Universe - he's a savage warrior who has the power to mind-control many wild creatures and has brute strength in abundance. He is also very dumb and has mostly been depicted as comic relief and not much of a threat to He-Man and his heroic band of warriors. His preferred forms of attack usually involve badly using a whip or charging recklessly at his opponents - both of which tend to fail. He's an absolute must for a movie, but he would have to be made at least slightly more threatening to be taken seriously (more so than the 1987 attempt) - because he certainly looks the part on that front.
