Alright I finally have an Idea of what I'm asking for.

This guy is sort of like if Batman made a deal with Venom to keep him alive as long as he feeds him.
It's a bit of a reductive take, but I don't want to infodump the entire act 2 of my script just to explain him.
'Venom' in this case is the Pure Demon of Wrath and Anguish. I haven't settled on a name but 'Wrath' has been a good enough shorthand. He is like the hulk where the angrier he gets the more powerful Wrath becomes.
'Batman' in this case I haven't really worked out a backstory on but like batman he has PTSD from a traumatic childhood that made him as righteous as he is. He fights to protect like your everyday capeshit hero, he just gets extremely violent and enjoys causing as much pain as humanly possible to his opponents before killing them.

The part I am actually having trouble with is using his design to establish these traits. The only thing I've settled on are the horns and eyes, as they are a mirror of the MC's and provide a good sense of movement while being fun to gesture. I provided some gestures in the corner to display what I mean. As for the rest he is just a tar black buff guy with a skull on his head. I might also make him fucking shredded but I'll need more practice before I can actually draw that...The skull was inspired by Phantom Ganon's concept art from Ocarina of Time, and I liked the concept.

The shape of the skull, whether it works as a mask or a head, and what I should put on his body I could use help with. I want to represent who he is by how he looks.
