MechMario is the boss of Bloopers Island. He has twin pistoles on his back and a submachine gun.
MechMario has 6 lives. At first, he will keep shooting bullets at you until you hit him. He will then jump and try to crush you, and then he'll shoot again. The Player should damage him as much as possible. Then he'll go shooting with a repeating rifle (as seen on the 2nd image). When defeated, he topples over and explodes.
- MechMario is the only clone to be a droid (robot).
