The Half Oni
"Half Oni 1: Hey have you seen the jailor recently?
Half Oni 2: Yeah, bastard tried to jail me so I smashed his head in
Half Oni 1: Right on brother."
Half Oni takes traits from both of their parents, usually for most Half Oni, they take the skin color and physical build of humans, while inheriting the hair color and horns of an Oni, they also sometimes may inherit the teeth or other such traits of an Oni but the human part of them takes a strong priority.
Half Oni and humans, at least body shape wise, are pretty similar, so it's not surprising that sometimes once in a blue moon, they may become partners or just mate once or twice. Out of all the half races Half Oni's are the most rare as biologically, Oni and humans don't have good compatibility genetically, as such Half Oni's are sometimes captured, sold, or killed and used like trophies. This foul practice has mostly gone away over time, however Half Oni's seem to hold this grudge against other races despite hundreds of years passing since that era.
Half Oni are extremely rare, as such, they usually live amongst other races, perhaps orcs or trolls, or humans, Half Oni's grow up feeling alone in the world as they know they're are very few of their species in the world, and even fewer people Amongst the people of the world who could ever accept them. As such they fundamentally are inclined to grow up and develop personalities that are twisted and extreme.
