Skeleton Joes are yet another Sniper Joe variant created by Dr. Wily that appear in Skull Man's stage in Mega Man 4. They attack Mega Man by throwing bone-shaped projectiles at him. If Mega Man shoots them with a standard buster shot, they will fall apart only to put themselves back together moments later. They can be destroyed completely with a fully charged buster blast, or with the Pharoah Shot or Flash Stopper.
