Super Arm

Super Arm (スーパーアーム) is Guts Man's Special Weapon in the Mega Man series. It is a special equipment that allows the user to lift and throw heavy rocks. Its power cannot be adjusted, so the user should avoid certain actions (like shaking hands) with it equipped.

Mega Man
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. Pressing the attack button near a flashing block causes Mega Man to pick it up (Mega Man cannot climb ladders while performing this move), and pressing the button again causes him to throw the block. If there is not enough room available to create an arc, or if/when they land on the ground, the block will scatter.

This is the weakness of Cut Man and CWU-01P. Alongside Elec Man, those three are the only bosses that can be hit by the Super Arm, as the rooms they appear are the only ones with blocks. Either the Super Arm or Thunder Beam is required to obtain the Magnet Beam.

In the mobile version of the game the Super Arm allows him to launch a chunk of block from his buster instead of having to pick and toss a huge block.

Mega Man Powered Up
Mega Man uses the Super Arm in the same way from the original Mega Man game.

When playing as Guts Man, he can pick up "Guts Blocks" from the sides and throw them at enemies, much like Mega Man, but he can also pick the blocks from above, and is able to summon a block in front of him while standing on the ground. Up to five blocks can be summoned in the screen. He can't summon them while in the air or on moving terrains, like Conveyor Belts and Drop Lifts. Also, blocks can't be summoned if an enemy or projectile is in front or below the place it appears. While enemies can't be crushed by the blocks, Guts Man himself can be crushed if one is not careful. Besides attacking, the "Guts Blocks" can be used as platforms, being useful to avoid hazards such as the spikes and Appearing Blocks, and trap enemies and bosses.

While the Wily Machine Number 1 is able to copy all weapons from the eight bosses, it can't use the Super Arm. However, sometimes Dr. Wily will throw a hammer when his machine is set with the Super Arm.

Mega Man: The Wily Wars
In the Wily Tower mode, the Super Arm can only be used in a single block present in the lower path from the first Wily Tower stage, blocking the path to a 1-UP and a large Life Energy. However, as the block can also be destroyed by Thunder Beam and the only enemies in its area are Foot Holders and a single Screw Driver, the Super Arm's usefulness is greatly reduced in this mode.

Mega Man: The Power Battle
In this fighting game, the player obtains the Super Arm by defeating Guts Man in the "Mega Man 1~2" course. The user launches a boulder from his buster. It is the weakness of Ice Man and Yellow Devil.

Mega Man 2: The Power Fighters
Like Mega Man: The Power Battle, the Super Arm is obtained from Guts Man in the "Recover the new parts!" course, and it releases boulders. This is the weakness of Air Man and Wily Machine.

Street Fighter x Tekken
Mega Man uses the Super Arm as his forward throw, lifting his opponent above his head and throwing them.

Super Smash Bros. series
The Super Arm appears in Super Smash Bros. for Nintendo 3DS / Wii U and Super Smash Bros. Ultimate as Mega Man's grab move. He uses his strength to pick up opponents and throw them in any direction inputed, dealing 6% damage when thrown forward, 11% when thrown backwards, 7% when thrown upwards and 5% when thrown down, with the opponent bouncing after hitting the floor when thrown down. While in Mega Man's grip, the grab or the attack button can be pressed to use the "Super Squeeze", dealing 3% additional damage before throwing the opponent.

Damage Data Chart
Known damage values for the original Mega Man.

Mega Man (Ruby-Spears)
Proto Man uses the Super Arm against Mega Man in the first episode of the Mega Man animated series. After showing annoyance at the other robots being unable to defeat Mega Man, Proto Man chose to go after Mega Man himself, copying Guts Man's power in order to help him to do so.

After chasing down Mega Man, he used Guts Man's power to punch him through a hangar wall, before following him through to continue attacking, but was unable to find him anywhere. Mega Man was able to get the upper hand against Proto Man, defeating him by knocking him into an aeroplane turbine, which fired him into a wall with immense force.

Its only visible effect was enlarging the size of Proto Man's left forearm, presumably to visually convey the extra strength granted by it. Interestingly, it was the only Special Weapon Proto Man ever copied from a Robot Master on the show. It is also one of the Special Weapons that was never copied by Mega Man, despite Guts Man being present in all episodes.

Mega Man (Archie Comics)
In the beginning of the first issue from the Mega Man comic by Archie Comics, Mega Man uses the Super Arm to open a path and get inside Dr. Wily's hideout. Prior to this event, in the second issue Mega Man obtains the Super Arm and uses it to defeat Cut Man. He also uses the Super Arm in Mega Man #3, #4, and #8.

Mega Man Megamix
When Mega Man is caught by the Yellow Devil, he uses the Super Arm to free himself.

Rockman (manga)
The Super Arm is the first weapon obtained by Mega Man, and he uses it to defeat Cut Man. Later, Mega Man tries to use it against Elec Man, but his Thunder Beam destroys the block. He also uses the Super Arm to open a path in Dr. Wily's hideout.

Trivia

 * Wily Machine is actually programmed to take 1 unit of damage from the Super Arm; however, it is impossible to do this during normal gameplay because there are no blocks in the battlefield. It can only be accomplished using an external cheating device such as Game Genie.
