Bodyless can be described as a cartoon animated head with incredibly bad luck.
No matter where he ends up in the grand multiverse, he always has cartoon physics.
Which means he's effectively immortal, as no matter what injuries he takes, he always survives.
He's very grumpy due to his bad luck, in addition to being snarky.
NOTE: Bodyless has only appeared in certain worlds, usually for the purpose of comic relief.
Since he's not a major character, he doesn't get a character sheet.
