In these hilariously-illustrated panels by Steve Hickner, from the He-Man episode "Return of the Gryphon", we see Orko trying to aid Man-At-Arms in the repairing of a freeze ray device. I particularly like the second panel with the pair shocked at what they know is about to happen! From looking at the many storyboards I own, Hickner clearly enjoyed illustrating Orko, as he always seemed to give the character a great deal of life. Something that was sadly not translated to the screen in his storyboards.
