Power Stone

Power Stone is Stone Man's power. When Mega Man uses it, three stones shoot out and spiral about. It takes some practice to use them efficiently. The Power Stone along with the Gemini Laser and Water Balloon is one of the more mundane weapons in the Mega Man universe.

In Mega Man 2: The Power Fighters, it launches a giant stone hand that rises from the ground and goes forward.

Capacity
Each use of Power Stone only drains one weapon energy unit. It's possible to use Power Stone twenty-eight times with a full weapon energy gauge.

Usefulness

 * Can be helpful to take out enemies in hard to reach (or dangerous) spots, such as the Power Massler in the second area of Wily's Castle (near the boss, Circling Q9).

Trivia

 * Capcom has a fighting game series called Power Stone.
