The Grenade Arm (グレネードアーム Gurenēdo Āmu?) is a Special Weapon from Mega Man Volnutt in the Mega Man Legends series that appears in Mega Man Legends. It is made from the item Grenade Kit. Mega Man throws grenades with this special weapon. He is immune to the grenade explosions and the grenade itself can bounce if it hits a wall but can explode upon hitting a Reaverbot. Like the bombs Horokkos fire, these bombs have a delayed explosion.
