Kirby (SSB)/Up tilt

Overview

The hitbox of Kirby's u-tilt.

Kirby does a vertical kick. It is widely regarded as among the best attacks in the game, and maybe even the series, due to dealing high damage (14% clean, 10% late), quick speed (hitting on frame 4 and being only 16 frames long, which is extremely fast and hard to counter), ability to break shields via repeated use (which is very possible due to the quick speed and is guaranteed up close,) ability to combo (can chain into itself for up to 70%+ depending on the weight of the opponent and percent,) and it's notably disjointed hitbox that covers the length of more than one Kirby both horizontally and vertically. It can easily lead into other moves such as back air or neutral air and it can lead to kill confirms. The weak hit box also has uses as it leads to kill confirms and into the strong hitbox (via pivot) at mid to high percents though it is not as safe on shield. This move is considered to be the main reason Kirby hard counters fast fallers and heavyweights such as Captain Falcon and Fox as it leads to early easy edgeguards when combined with aerials. This also lends to Kirby having the strongest matchup in the game against Yoshi along with Captain Falcon as it can easily break double jump armor. Along with back air and down air, these moves are the primary moves in Kirby's arsenal especially when combined with pivots.
