Little Mac (SSBU)/Down tilt
Little Mac moves slightly forward when crouching and punches downwards in front of him. It's tied with Ness, Lucas, R.O.B and Meta Knight for the fastest startup of any down tilt, coming out on frame 3, and has low ending lag. It has a slightly disjointed hitbox at the fist and impressive range, even in comparison to swordfighters, and has a vertical angle that makes it one of his most reliable combo starters. At high percents, it can combo into Jolt Haymaker or Rising Uppercut for a KO confirm, especially when 2-framing. However, down tilt's combos are harder and less reliable because of its higher ending lag, although it's still a good combo starter. This makes it one of Mac's most important options for its metagame.
The move disables jostling during frames 1-5.
