I'm trying to find the best way to describe being so physically deformed, that its only, somewhat recognizable, feature is its own body shape. Mutant doesn't work for me, as it implies the reason of deformation, and I need something more general. Freak seams right, but sounds silly to me, so I hopping for something else. I was thinking about word chimera, but I'm not sure if it's the right way to use it.
Also, I don't care how offensive the word is. Thank you.
