In this page of storyboards by Bob Kline from the season one He-Man episode "Diamond Ray of Disappearance", we can see that during the battle outside of Castle Grayskull He-Man was originally going to punch Beast Man! Now, for those that know the cartoon and the strict rules it placed upon itself, this scene could never take place. He-Man was never allowed to commit violent acts against the enemy. As such, these scenes have a large cross through them implying that they would not even make it to the layout stage!
