I always thought that this panel from "He-Man's Gamble" that appeared in issue sixty-five of the UK Masters of the Universe comic was an interesting one. I like the way in which Prince Adam is trying to explain himself to Teela as they stroll along. Teela's pose, even though it is not supposed to be, looks like she is flirting with Prince Adam, or at the very least posing for him. The story itself is memorable, with Prince Adam and Orko hatching a plot to convince Teela that Adam is no coward, only for it to backfire on them.
