Luigi ladder
The Luigi ladder is a technique in Super Smash Bros. Melee. It involves two Luigis repeatedly using their Super Jump Punch against each other back and forth. As the move causes flinching, but produces no knockback when not sweetspotted, the two Luigis can do this constantly. Passing the upper blast line only results in a KO when the target takes knockback.
The Luigi ladder is banned in tournament play, though this, of course, is only significant in doubles. Since Friendly Fire is turned on in standard tournament rules, a team of two Luigis could execute the technique and create an essentially unbeatable stalling technique.
The technique can be performed to some degree in Super Smash Bros. Brawl, but since the sourspot produces a nonzero amount of knockback, it can no longer be used past the upper blast line without KO'ing one of the Luigis. It can still be used to gain any amount of vertical distance (such as for recovery, although it is very situational) or to stall against a ceiling.
Trivia
- It is also possible to perform the Luigi ladder by having both players Super Jump Punch on the same frame, creating a much shorter jump which gives control back to the players much faster and in a synchronised fashion. However, as both Luigi's must be next to each other, the uses for recovery are far more limited, and avoiding the helpless state is purposeless when stalling.
- This is also possible (though generally more difficult) with other characters, notably Samus's Screw Attack. Note that these characters cannot stall indefinitely, as the attacks cause hitstun.
