Air Stone

Air Stone is an enemy from Mega Man 11. It's a small security robot that uses advanced optical technology to stay invisible most of the time. However, if Mega Man gets too close, the Air Stone will reveal itself and, if not destroyed quickly enough, shoot out eight small stones and then turn invisible again. It appears in Block Man's stage.

Air Fire
Air Fire is a variant of Air Stone seen in Torch Man's stage. It is exactly the same as the Air Stone, except it shoots out fireballs instead of stones.

Air Nut
Air Nut is another variant of Air Stone, created by Dr. Wily specifically to protect his Gear Fortress. This one appears in the first Gear Fortress stage and shoots metal nuts instead of stones.
