on design?

I recently bought a on with a rat on it. Now; the backround is half red and half black and the rat is vicious-looking. I purchased this item because I adore rats, but after I've given it a little thought, it seemed to me that this could easily be a logotype of some sort. And I really don't want to walk around with a on that represents a band I might not like or some sort of movement I'm not a part of. I browsed the web but couldn't find anything. So I'm asking you guys if anyone recognises a smirking rat with sharp claws on red&black background as a mascot of something? I know it might be a silly question, but I would appreciate any answers you can give me. Thanks! :)
