I remember being really into He-Man as a kid (btw, I would have loved to have seen the marketing meeting to see the guy who actually came up with the idea to name the show "He-Man." I'm sure the office threw him a free lunch that day.) and I don't really much care for it now. So I don't have any kind of real attachment to the characters more than the main characters, their wacky names, and crazy costumes.
I drew this from a random picture online found here I like the graytones and just smudged it with my finger to give some color contrast. To add a little magic, I just erased in the letters at the top left to read "Orko" as if they appeared from nowhere.
I would like to point out in my search for reference I found this awesome Orko drawn by UK artist, Rob Jackson on his blog.
