Well, I used to draw this weird Prototype ripoff thing called "The Stitch", and he was the first character I had. The idea got pretty far before i started doodling other stuff, and after 3 or 4 redesigns, I eventually gave up and let it be. I don't even do anything with the character, but anywhere I go I use the name i'll never forget.
EDIT: if I stumble across a picture of him, I'll slap it on here for everyone to mock.
