Kirby (カービィ, Kābī) is a starter character in Super Smash Bros.. He is known for being a small and light character with quick, surprisingly long-ranged attacks, as well as some strong moves and a great recovery.
Kirby ranks second on the current tier list. His attacks are quick and strong, with a few moves capable of KOing under 100% such as his forward smash, and powerful edgeguarders, such as his down aerial (which is also a meteor smash). His back aerial, forward aerial, and up tilt are great ways to space against the opponent, especially the latter - Kirby's up tilt is considered one of the best attacks in the game and maybe even the series due to its huge disjointed range, very quick speed, good combo ability, and ability to easily break shields if used repeatedly. Kirby can also go offstage pretty safely, with his recovery granting a large distance (on par with Pikachus), though it's a bit on the predictable side, along with it not being able to be utilized quickly. Kirby additionally has somewhat limited combo ability outside of up tilt and forward aerial on some characters, with his moves outside those two not stringing into each other too reliably. Kirby's main problem is his light weight and being moderately floaty, making him vulnerable to juggling and vertical KOs from characters such as Fox.
Kirby is a small, light, and somewhat floaty character. He is relatively difficult to combo horizontally and offstage, though is vulnerable to juggling and many vertical KO techniques (as well as not being too hard to KO horizontally either). His "signature move" is Swallow, which allows him to use an opponent's neutral special move and copy their apperance.
In general, Kirby possesses quick yet powerful moves. Some of his moves are infamous for possessing high range and being able to space well, most notably his up tilt (which covers the range of more than one Kirby both horizontally behind him and vertically), as well as his forward and back aerials. This makes a Kirby playing defensively correctly rather difficult to punish. However, Kirby's defensive ability is hindered slightly by his average to below average movement speed, with average dashing and walking speeds, low air speed, and below average falling speed. Kirby's smashes are powerful, especially his forward smash, which is by far the best forward smash in the game due to being the most powerful, having quick startup (though it has a bit of ending lag), and being an excellent punish or panic option. Kirby's throws are also fairly powerful, with his good grab allowing him to utilize them efficiently.
Kirby's up tilt and forward aerial are especially useful combo moves. The former can easily chain into itself at lower percentages and lead into aerials, a forward smash, or a up smash, while the latter is a great damage racker, being a very fast multi-hit move with the first few hits having set knockback, allowing them to lead into the final hit easily. The move can deal over 20% damage, and if the final hit isn't landed, it sets up a jab that can jab cancel into a grab to rack up further damage.
Kirby has an excellent recovery and offstage game. He has five midair jumps, and his Final Cutter not even extends his vertical recovery even more, but allows Kirby to also move to the side while using it by tilting the control stick. While his recovery travels a spectacular distance (only rivaled by Pikachu's recovery), it is somewhat predictable, due to being on the slow side and Kirby's slow air speed. His aerials can be used to edgeguard easily, especially his down aerial, which is a strong meteor smash that can also drag opponents down at lower percentages due to being a drill attack. With Kirby's aforementioned excellent vertical recovery, it is also easy to recover from.
Kirby's main weaknesses are his light weight and floatiness, somewhat lack of reliable combo options outside the basic up tilt and forward aerial, and a lack of ways to KO onstage outside forward smash. He is additionally easy to juggle, being vulnerable to vertical combos from Fox, Captain Falcon, and others to a lesser extent. Overall, Kirby has above average matchups, only losing to Pikachu on Dream Land and arguably Fox on Hyrule Castle, with an even matchup against Mario on both stages.
 In Competitive play
 Notable players
 Inhale Sacrificial KO
Kirby can use his Inhale move on opponents and fall to the map's bottom blastzone for a sacrificial KO. However, Kirby can "spit out" his opponent under the stage (particularly useful on Dream Land and then recover. Yoshi is the only character who is practically guaranteed not to be able to recover from this.
 Final Cutter spike
The Final Cutter can spike opponents on the way down during its initial frames (approximately until the same height from which the Final Cutter was initiated).
 In Single Player
In Single Player mode, the player must face eight Kirbys in succession with each Kirby wielding the power (and the hat) of the original characters beside Kirby and Kirby himself or a secret character's hat.
Defeating all of the Kirbys that appear in order rewards the player the Kirby Rank bonus, giving 25000 points.
 From the Game
The 8-inch high Kirby hails from a distant, peaceful star. Like his simplistic appearance, he is an easily-understood character. True to his instincts, Kirby eats when he gets hungry and sleeps as soon as he grows tired. Nevertheless, Kirby remains a formidable opponent. In addition to his distinct flying and swallowing skills, he also has the ability to copy enemy attacks for ever-changing action.
