The Green Missile is Luigi's forward B in Super Smash Bros. Melee and Super Smash Bros. Brawl. It can be charged for about three seconds, to then release a kind of jump that shoots Luigi left or right. It also is his primary third jump.
The move also has a 1 out of 8 (12.5%) chance to be a spontaneous misfire, that acts like if it was fully charged, but more powerful. It's not always beneficial, however. One possibility is Luigi charging the Green Missile and aiming at an opponent. He fires, but the misfire applies and the opponent dodges. This can very often prove hard to get back onto the stage for recovery. It also leaves the Luigi exposed to edgeguarding. In Melee, the spontaneous misfire fires Luigi extremely far. This has been toned down in Brawl, lowering the chance of a spontaneous misfire SD.
For some reason, computer-controlled Luigis in Melee will always use Green Missile to recover, instead of Super Jump Punch. This may be related to the fact that Luigi's Super Jump Punch is completely vertical, with no horizontal movement, but the computer-controlled Luigis will even use Green Missile when directly below a ledge.
In Super Smash Bros. Brawl, this move can be held at full charge indefinitely, and if a partially charged one it hits a wall, occasionally Luigi will get stuck for a brief moment and have to pull himself free. Also, CPU Luigis will now use their Super Jump Punch when they're right under a ledge, but they will still use Green Missile if they they're within horizontal distance of a ledge.
