Editing Kirby (SSBU)

Overall, Kirby is a close-range character who can rack up impressive damage at close range, complemented with his quick frame data, but struggles to make use of his strengths due to his unimpressive range, slow air speed, and built-in lightweight properties. As a result, Kirby is a rarity within the metagame. Nevertheless, he has still seen success from dedicated mains such as {{Sm|Guilheww}}, {{Sm|JeJaJeJa}}, and {{Sm|Konokururu}}.

Kirby's greatest strengths are his quick frame data, high combo potential, and the versatility of his moveset. The majority of Kirby's attacks are characterized by speed, with his tilts being among the fastest in the game, while his slowest moves instead boast high power as a trade-off, while still being quite fast for their power. Neutral attack and forward tilt are fast and have decent range, allowing Kirby to quickly distance opponents, with the latter being used for tech chase setups. Up tilt's low knockback and high speed allow it to combo into multiple moves, such as itself, an aerial attack, or an Inhale. Down tilt's low power is compensated by its very fast speed and it launching opponents at the [[Sakurai angle]], which allows it to [[trip]] most opponents even over 80%. Should he trip his opponents with it, he can follow up with a variety of attacks, such as a dash attack, grab, or forward smash. Dash attack’s early hit is excellent for whiff punishing and scoring a KO, potentially KOing opponents starting at 90%, while the late hit can set up into an Inhale. His [[smash attack]]s have good range, high power, and great speed, making them excellent at scoring a KO. Kirby is also very small, making him hard to hit, and his very low [crouch]] allows him to avoid almost all grabs and several attacks. As a result, Kirby has an excellent ground and defensive game thanks to his quick frame data and evasive crouch, requiring opponents to be careful when approaching him in neutral.

Kirby's [[special move]]s can provide some unique strengths. {{B|Inhale|Kirby}} is his most notable example; it allows him to either [[List of Copy Abilities|copy]] the [[neutral special move]] of any character he inhales, or spit them out as a weight-dependent [[projectile]]. Depending on what character he inhales, the copy ability can give Kirby a move that helps him in matchups to various degrees, such as useful projectiles to counter-camp his opponent ([[Needle Storm]], [[Charge Shot]], {{SSBU|Wolf}}'s {{b|Blaster|Wolf}}), powerful punish options ([[Giant Punch]], [[Homing Attack]]), a reflector ([[Nayru's Love]]), or other benefits ([[Monado Arts]]). In addition, Kirby's version of the opponent's neutral special has a 1.2× damage multiplier. Kirby can also inhale projectiles; smaller projectiles will be swallowed, allowing him to heal himself, while larger ones (such as a fully-charged Charge Shot) can be stored in his mouth and spat out, essentially giving Kirby a reflector. The spat projectiles can be used to punish opponents at mid-range and can launch them away with high knockback. Inhale can also be used to [[Kirbycide]] or spit the opponent out offstage, although the opponent can escape by [[mashing]]. [[Hammer Flip]] is very powerful, especially when fully charged, and Kirby can move and jump while charging. However, its high startup and endlag, along with its short range and Kirby's already-sluggish movement being further slowed when charging, makes it difficult to land outside of a [[shield break]], covering ledge options, or after a jab lock. Outside his jumps, Final Cutter is his primary means of [[recovery]], granting good vertical distance, as well as a disjoint in front of him during his ascent and descent. It also emits a shockwave projectile upon landing, making it difficult to [[punish]] if the opponent is not behind Kirby. Lastly, [[Stone]] causes Kirby to turn into an object and ignore up to 25% damage. It is also a strong attack, especially in the air, and can be canceled shortly after Kirby begins his descent, although these benefits are limited by its slow startup and ending lag, and Kirby is still vulnerable to grabs while transformed. It can also be used on the ground, where it has faster startup due to creating a shockwave and it launches at a semi-spike angle.

Kirby's most notable flaw, however, is his poor approach. Characters who have high mobility or who can camp with projectiles can wall out Kirby, such as {{SSBU|Sonic}} and {{SSBU|Samus}}. Kirby's lack of reliable burst options makes his approach in these matchups problematic and sometimes predictable. In addition, characters with long [[disjointed hitbox]]es such as {{SSBU|Cloud}} can outrange and wall out Kirby since his range is short relative to the cast. Final Cutter's projectile has decent range and moves quickly, but has somewhat slow startup due to it requiring Kirby to perform the entire rising and falling portions of the move beforehand, and he lacks other projectiles outside of spitting inhaled projectiles/opponents, or from a copy ability. This requires conscientious use to avoid punishment. Despite having great air acceleration, Kirby's air speed is also too slow for him to take advantage of it, hindering his aerial approach and recovery despite possessing five midair jumps. Kirby also has several KO moves, but some can be hard to land without a setup due to their short range. [[Rage]] further compounds these issues, as Kirby will be launched even further by a high-damage opponent, and his low weight means he will sometimes not survive long enough to take advantage of his own rage.
