Power Piston

Power Piston is the boss of the second Mr. X stage in Mega Man 6, and is located at the hallway's end. It stays attached to the right wall, moving up and down, and stomps it to make boulders fall down. The best weapon to hit it with is the Silver Tomahawk, however, it takes practice to aim it properly. The player can also use Blizzard Attack if they run out of Silver Tomahawk.
