Super Arm

Super Arm is Guts Man's power. In Mega Man 1, the Super Arm does not fire on its own. Instead, you walk up to certain blocks, and if they can be picked up by the Super Arm, they flash. Press the attack button to pick them up, and press it again to throw them. If not enough room is available to create an arc, or if/when they land on the ground, they scatter. In the two arcade games, boulders appear for you.
