|Mega Man with the Power Stone equipped.|
The Power Stone (パワーストーン Pawā Sutōn) is Stone Man's Special Weapon from Mega Man 5. It is a group of three stones that spin outward in a spiral formation. The weapon has the potential to deal high damage, but is difficult to use against small or long-distance targets.
The Power Stone is one of the weapons to appear in the Megamix Engine. It is unchanged from Mega Man 5, and deals four points of damage to any enemy in the Flying or Floating category, while dealing two points of damage to all other enemies.
The Power Stone is also among the special weapons available in the Example Game, obtained by defeating Stone Man.
