I was too lazy to remake it, so I took the one  BlackpawWolf posted.
I'm not sure who the original artwork was by but here's a link to the post Blackpaw did:

So I'm changing a lot of the information just because I see him differently. His age is younger, maybe around 20 years old. He acts more like a teenager, getting into trouble and caring more for himself. He's very bouncy and active and can be a sweetheart (sometimes).
He's also part fire demon and can control fire and generate it from his body. He doesn't really remember his past and he doesn't really know how to control his power. He has a full demon form, but I'm still figuring that part out.
Also his height is 5' 3" so he's short.
