Gum-Gum Pistol

Gomu Gomu no Pistol (ゴムゴムのピストル, Gomu Gomu no Pisutoru, lit.: Rubber Rubber Pistol) is 's standard special move in Super Smash Flash 2. This move allows Luffy to stretch his arm forward, reaching out for a nearby opponent. If it connects, Luffy pulls them into his grab, and thus, can pummel and throw them.

The move can also be used as a tether grab to aid Luffy's recovery.

Origin
In One Piece, one of Luffy's signature attacks is Gomu Gomu no Pistol. However, in the anime and manga, the move is used as a punching attack as opposed to grabbing as seen in SSF2.

Luffy's first use of the move in the series was in Chapter 1: Romance Dawn when he defeated the local sea king in East Blue. However as a child, Luffy created the move saying that "His punch was as strong as a pistol" though lacked the training and failed to properly use the move on many occasions. Since then, there have been many occurrences and different variations of this attack preformed by Luffy throughout the series.
