Super Arm

Super Arm (スーパーアーム) is Guts Man's power. In Mega Man 1, the Super Arm does not fire on its own. Instead, Mega Man must walk up to certain blocks, and if they can be picked up by the Super Arm, they will flash. Press the attack button to pick them up and press it again to throw them. If there is not enough room available to create an arc, or if/when they land on the ground, the blocks will scatter. In the two arcade games (Mega Man: The Power Battle and Mega Man 2: The Power Fighters), boulders appear for Mega Man.
