Announced at E3 2001, Kirby (カービィ, Kābī) is a starter character in all three games of the Super Smash Bros. series. Although tier-wise he was the second-to-top character in Super Smash Bros. topped only by Pikachu, in Super Smash Bros. Melee, he became severely nerfed.
Currently, Kirby is ranked in the F tier at 26th place, at the very bottom of the tier list. Among Kirby's best attributes include the ability to perform Kirbycide and a rather good edgeguard game, especially when combined with his Fence of Pain. Additionally, Kirby has a very good defensive game, due to his small size. However, Kirby's overall power has been strongly nerfed from the previous game. A majority of his attacks are considerably weaker and have smaller sweetspots, making Kirby's KO options now few and far between. Kirby also has awful approach options, due to a poor SHFFL and the lack of a good projectile without copying one from Inhale, and went from having one of the best combo abilities in SSB64 to one of the worst in Melee. This, combined with a rather predictable recovery and a ease of being comboed because of his poor hitstun leads to Kirby to have generally abysmal matchups against other characters, with seven very unfavorable matchups; despite this, and his last place ranking, he does have two favorable matchups against Bowser and Roy.
Kirby's signature move is Inhale, which allows him to use opponents' neutral special moves. Kirby is also known for having five midair jumps (although the last couple of jumps barely give any height) and floaty descent, which gives him good recovery distance. However, his recovery is still slow and predictable. His multiple jumps also allow for good edgeguarding abilities and good midair evasion (due to slow falling speed when normal and fast falling speed with midair transformation). Kirby's small size, quick dodges, and low crouch (one of the lowest in the game) enable him to have good evasion. He also has a large shield in relation to body size, which makes him difficult to shield stab. Kirby is arguably the character most famous for his sacrificial KOs, Kirbycides. These are extremely useful in certain scenarios, but his back throw and forward throw can be intercepted. When Kirby is in stone form, he does not take damage (although he can be grabbed out of it).
However, Kirby has several significant problems. Many of his moves are slow, weak (almost all of his moves have tiny sweetspots), and short-ranged. He is easily KO'd due to being light and floaty (and he can't escape most combos because of these things due to having a high amount of hitstun when hit.) He has poor combo ability, his SHFFL'd aerials are slow, and his up special (Final Cutter) does not have good horizontal range. Also, his grab game is very limited. As aforementioned, his back and forward throw can easily be intercepted due to them being easily shaken out of and left Kirby to die, and only down-throw can be used to land another move. Kirby has a very small wavedash, making wavesmashing difficult to perform. Lastly, Kirby's new special move, the Hammer, is extremely slow, weak and punishable if not sweetspotted, which is hard to do as the sourspot is much larger than the sweetspot.

 Changes from SSB to Melee
Kirby was unarguably the most severly nerfed character of the Smash series. Below are the changes:

 Tier placement and history
Kirby has traditionally always ranked very low on Melee tier lists; compared to Pikachu, Kirby's nerf from Super Smash Bros. was far more severe, leaving him with very little options. Kirby's only positive traits are his relatively decent edgeguarding ability and his ability to Kirbycide; however, Kirby is seriously lacking in every other area, with an abysmal approach, a horribly laggy new dash attack, and almost no ways to KO enemies outside of Kirbycide because of poor hitbox placement on almost all of his attacks, with his up and back aerials being the only things that can KO reliably without extremely high risk. Because of these terrible traits, no active, professional smasher has picked up Kirby for serious play. Kirby is ranked last on the tier list because he is viewed as the character with the least potential due to these traits, as well as his lack of representation in tournaments; no dedicated Kirby player has even placed in the top 96 of large tournament in the past few years, and the only Kirby players who would stand a chance are inactive. Kirby has competed for the last place position along with Pichu over the past years, and as of the current tier list, is one place below Pichu.
 In Single Player Modes
 In Classic Mode
Kirby appears in a one-on-one, as an ally, on a team with Pichu, Jigglypuff, Pikachu, or Ice Climbers, in a multi-man battle, or in a metal battle. Kirby appears on Battlefield in the metal battle and on Icicle Mountain on a team with Ice Climbers. Otherwise, he appears on Fountain of Dreams or Green Greens.
 In Adventure Mode
Kirby's sole appearance is on Stage 5: Green Greens. He first appears in a one-on-one fight then 15 Kirbys appear each possessing a copy ability. If the single Kirby and the Kirby team are KO'd in less than 31 seconds, the player must fight a giant Kirby.
 In All-Star Mode
Kirby and his allies are fought on Green Greens.

 Trophy descriptions
Kirby is the single most represented character in trophy format in Super Smash Bros. Melee. Being a playable character, Kirby has his own set of "gameplay" trophies that are acquirable by completing any of the three modes in the single-player modes with Kirby: Classic, Adventure, and All-Star.
Kirby is also the subject of five trophies that can be considered its own trophy series: the Kirby Hat series, with information about the powers Kirby gains when he uses Swallow on each opponent. The first three are "normally collectible" trophies that can be found during normal play and in the Trophy Lottery, but the last two are awarded once the player has unlocked all the playable characters involved on those trophies.
Finally, the character Kirby himself is depicted on some other trophies not related to gameplay: Ball Kirby, Fighter Kirby and Fire Kirby.
