Marth (SSBM)/Up tilt
Marth swings his sword in a large arc above his head. Marth's up tilt is an extremely versatile move. Its speed and large vertical disjointed hitbox allows Marth to extend his already potent stage control on to low platforms, particularly the ones on Pokémon Stadium, Yoshi's Story, and Battlefield. Against fastfallers, Marth will use his up tilt in his up throw chain grab to either combo into a regrab, a string of aerials or more up tilts and a subsequent forward smash to finish off the opponent.
Marth's up tilt serves as his primary KO move on floaties, often set up with the first hit of Dancing Blade. The move has rather high knockback growth compared to some of Marth's other KOing moves and is thus especially good on large stages like Dream Land, where Marth often has difficulty KOing floaty characters.
