"Grumpy Meteorite." You’d be grumpy too, just floating out in space like that. It’s really a meteoroid, but I figure "meteorite" will sell better in Hollywood.
Edited 08/15/2011 to add: Nobody’s asked, but if anyone wondered, I doodled this before I ever played Portal 2 or knew about the Space Core meme, so this doesn’t have anything to do with that. Just random doodling.
