Gum-Gum Pistol

Gum-Gum Pistol is 's standard special move in Super Smash Flash 2.

Overview
When performed, Luffy stretches one arm a great distance forward. If it connects with an opponent, Luffy will then pulls them into his grab, and thus, can pummel and throw them. If it connects with an opponent in the air, the opponent will simply be let go of when they reach Luffy, though they can still be held if Luffy reaches the ground before then.

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

Origin
In One Piece, one of Luffy's signature attacks is Gum-Gum Pistol. However, the move is actually used as a punching attack as opposed to grabbing, as it's used 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 he 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.

In the game One Piece: Grand Adventure, Luffy uses a similar move called Gum-Gum Impact which utilizes him grabbing his opponents from afar and attacking when up close.
