Super Arm

The Super Arm was originally one of five special weapons that could be changed into 's standard special move with the Weapon Change in Super Smash Flash 2. As of Beta, Weapon Change has been replaced by Water Wave, thus taking this move along with it. However, Mega Man still uses Super Arm as his grab animation, though it's completely different in functionality.

Overview
When performed, Mega Man would change color to yellow and take out a large yellow block before tossing it forward with both hands. The block would travel in an upward arc and at a decent speed. When coming into contact with anything after being thrown, the blocks would separate into four pieces. A block would deal 9% of damage and moderate knockback to the opponent whom is struck.

Origin
The Super Arm is a weapon originally acquired by defeating Guts Man in the original Mega Man. In this game, the player would have to find certain blocks somewhere in the level that would flash when Mega Man is near them. He would then be able to pick one up and then throw it to attack enemies, though Mega Man is unable to use different weapons or climb ladders while carrying a block. It was also Cut Man's weakness and most effective weapon to use against him. In SSF2 it functions similarly to its Mega Man counterpart, except Mega Man doesn't need to find a block on the ground; he simply pulls one out of thin air.

Trivia

 * Oddly, the blocks would not break after hitting an opponent if they're hit at the very beginning of the throw.
