Green Missile

Green Missile is a recurring attack in the Super Smash Bros. series also usable by Luigi in the Super Smash Flash series.

Overview
The attack consists of Luigi rocketing himself forward headfirst in the manner of a missile, damaging opponents that come into contact with his head.

In the original Super Smash Flash, Green Missile is 's down attack. Luigi travels relatively far when using this move, and it's also quite powerful. Despite its appearance, the move does not launch Luigi into the air, as it functions like a standard sliding attack and is affected by gravity at all times.

For the reboot, Super Smash Flash 2, Green Missile is 's side special move and now it works more akin to its Super Smash Bros. counterparts: he now gets launched into the air, cancelling his vertical momentum and ignoring gravity until the move ends. When it does end, he will fall onto his side before getting back up, or flip back over if he's still in the air. He can also now charge the move, entering a crouched position and surrounding himself with green particles as he does. The amount of distance covered along with how much damage and knockback the move does depends on how long the move is charged. However, there is a chance of a "misfire" happening, which will drastically increase the distance and knockback of the move. The chance of a misfire happening is 12.5% on the ground and 8% in the air.

Trivia

 * If Luigi misfires and hits a wall in SSF2, he will get stuck for a brief moment and have to pull himself free, accompanied by a spring noise as his body bobs up and down for comedic effect. This feature originates from Super Smash Bros. Brawl and is also present in Super Smash Bros. for Nintendo 3DS and Wii U.
