Obsidian Bone Oni

Obsidian Bone Oni wwere fragments of one of the most massive horrors of Jigoku, and were rarely seen far from the Festering Pit. Not long after the creation of the Festering Pit, an oni of inestimable size attempted to force its way through into the Mortal Realm, but the effort shattered the being, sundering it into lesser horrors. Even these beasts were too large and horrific to maintain a presence in Ningen-dō, and so cunning servitors of Fu Leng drove massive spikes of Pit-forged obsidian into the bodies of these monsters, sustaining them, but at a terrible price: the flames of Jigoku burned constantly within their bodies, driving them to new heights of desperation and cruelty.
