I can confirm there was a Spawn 'Clix... Two paintmasters were created and a dial was statted out, but it was never actually 'manufactured' - there was never a version with printing on the dial I mean. One paintmaster went to McFarlane, who ultimately decided not to allow Spawn to be used in the game, and the other went to our sales guy. I've heard a couple of conflicting reasons for why the character wasn't manufactured, one being that McFarlane wanted his cape to be cloth, the other being that McFarlane didn't like the sculpt and wanted to do it himself.
