This is Voidbringer, a dragon hybrid of two tribes: skywings and nightwings. He is an assassin and a saboteur, but calls himself a mercenary. In fact, his mask is enchanted to transform any dragon to Voidbringer and also contains the soul of Cinnabar. Venomous wears that mask to disguise himself from others and shares a body with Cinnabar, who will take control after some "synchronisation". Also nobody can remove the mask but it's carrier himself. Voidbringer uses a crossbow on his left arm, small grenade like bombs and the set of throwing knives.
Wings of Fire belongs to its owners.
Voidbringer belongs to me.
