Capabilities: A person who has consumed this fruit can grow bones at will, even on the outside of his/her body, the weight and thickness of his bones are up to him/her and these bones can be used as projectiles, weapons or armour. They can grow thick enough to stop a bullet, but anything stronger than that eg a powerful punch can break it. The amount of bones that can be grown are limited, if he/she already has a thick armour on, they are limited to a single weapon bone, if there is no armour they can have 2 weapons.
