Version 2 of onyx. I think his old outfit will be his homeworld outfit.

I think they are fond of old music and black and white movies, and use death’s head knuckle dusters. He has two gems, one on the middle knuckle on each hand. Bottom left is something we’ve seen before. It was supposed to be example of him without his hat, but the multiple eyes/mouths show up when they are stressed or angry.
