I drew the original for this in Microsoft Paint in 2000; it's about the size of a postage stamp and was never colored.
Right now I'm going through my bazillions of art, writing, and photo files to eliminate duplicates and consolidate all of my digital creative output in one place. I keep running across sketches and unfinished ideas and my imagination keeps sparking on them. Like this one, most don't have stories to go with them. They were created and abandoned. In a lot of ways, I'm surprised that they exist at all.
