Luigi (SSBU)/Dash attack

Hitbox visualization showing Luigi's dash attack.

Overview

Luigi childishly throws punches whilst dashing forward. His second fastest grounded option, out-sped by his frame 2 jab, Luigi's dash attack makes for his best burst option, and especially useful when perfect shielding a longer ranged move. At high percents, it is able to KO opponents, making it great for when Super Jump Punch cannot reach in time or when dash grab is too slow, although the lengthy animation and high hitlag multiplier on the final hit make it easier to DI on reaction. While it is possible to SDI the move, the low hitlag multiplier of 0.5x makes it a bit more difficult to do so, however it can fail to connect when used against the ledge due to the 0 degree angle on the first four hits, which also makes it connect worse when the hits are spaced out. It is also very unsafe on shield even if it crosses up, and if it completely whiffs, the lengthy animation can lead to a punish on Luigi.
