Enris

Enris is not fully human, he is half a parasite. His berserk form is not hand-made nor did any humankind invent it. It's apart from his body by summoning it. He also has dragon form on four legs, which barely appears as it is too powerful and massive. It may be out of control. - In this one, he's in his first phase of his berserk form. Keep in mind this is in 1700s era. You can change if you want. Have fun.
