Update: i thought in a possible story for this character. He is a demon who scaped from hell by accident. Since then he started a new life, it was hard and specially violent, all mortals fear infernal beings. But he was more scared than the rest, he didnt ask to be dragged out of hell, alone and he lost almost all his power and strength.
Over time, he was able to survive and know the world better. He had a series of experiences that made him see the mortal world with a certain beauty and curiosity. Now he is more known as strong warrior and mercenary. Most people are afraid of his tall stature and demonic wings, many think he is a tiefling with more infernal ancestry than the usual.
He is someone very perceptive, not very talkative, but he doesnt miss a detail. He likes meditate on their thoughts and the mortal world, it’s people, emotions, the fragility of all beings. Things that in hell can never emerge. He find them very interesting and sometimes he feels a thought of protection.
Some struggles with face designs, this is the second hardest part. The first one is the name
Working a possible character for adoption: daddy demon warrior
