Here is a particularly interesting storyboard panel from the season one He-Man episode "Ordeal in the Darklands". Storyboard artists often began illustrating there boards with no final character models provided and would create their own versions of the characters. In this panel by Warren Greenwood he has created his own versions of Kor and Mira. What I find most amusing about this image is that Mira resembles the action figure Battleground Teela released a few years back in the Masters of the Universe Classics toyline!
