I hope you don't mind seeing my original characters on the post section.
For my original project, Black Thorn. The story takes place in a world where demons are hunted down for their essence and then sealed into objects called Relics. Relics are used to either aid human hunters or seal away the most dangerous monsters.
This is one of the Main Characters, Balthazar. He is one of the remaining demons who haven't been extracted of their essence and takes cover working at a traveling museum. This outfit he has maybe his curator outfit and when he deals with hunters and other threats. He always has his third eye covered in public with his one of many disguises. He carries a Relic, dubbed "Black Thorn," which emanates a dangerous strong aura.
Let me know if you have questions, 1st impression assumptions, and I'll try to respond.
