* DevelopmentHell:
** Between ''Kirby's Air Ride'' and ''Kirby's Return to Dream Land'' (''Epic Yarn'' was developed by Good Feel instead), HAL Laboratories made repeated attempts to create a home console game for the ''Kirby'' series. Their most known attempt was the UsefulNotes/NintendoGameCube game, announced in 2004, and widely believed to be reincarnated as ''VideoGame/KirbysReturnToDreamLand''. However, [[http://www.nintendo.co.jp/wii/interview/sukj/vol1/index.html an interview]] revealed that the [=GameCube=] game was only the first of ''four'' attempts at a home console game, the final being ''Return to Dream Land''.
** ''Kirby Air Ride'' itself was trapped in DevelopmentHell for quite some time. It was originally intended as a UsefulNotes/{{Nintendo 64}} launch title, but after spending many years in production, it was quietly canceled. It finally showed up as a [=GameCube=] title at E3 2003.
* ExecutiveMeddling: Rumor has it that Masahiro Sakurai left HAL because this happened during the development of ''Air Ride''. He also stated in an interview that he didn't like the sequelization of the gaming industry.
* FandomLifeCycle: Despite being a long-running series that sells well, having a very recognizable main character, and being adapted into a generally liked anime series, ''Kirby'' is only in Stage 2/early Stage 3. This can be attributed to the games' [[TastesLikeDiabetes limited appeal]] to the bigger game demographics (which also resulted in some CriticalDissonance for the earlier games), inconsistent releases during the 2000's (such as only having 1 GCN game and not getting a Wii game until 2010 which was a SpinOff), and being overshadowed by other Nintendo franchises. This may be changing, though, as big representation in ''VideoGame/SuperSmashBros Brawl'', a stronger release schedule since beginning of the 2010s, and the overall great reception of the games from ''Return to Dream Land'' onward have given it a lot of attention.
* FanNickname:
** King Dedede is sometimes referred to as "DDD", "Triple-D", or "3D".
** Meta Knight is often called "MK". The Japanese fans sometimes call him "Papa Knight" for his anime portrayal, i.e being shown to care more for Kirby than in the games.
** The bandana-wearing Waddle Dee that served as Dedede's right hand in ''Super Star Ultra'' was referred to as Bandana Dee, which became [[AscendedFanon Bandana Waddle Dee]] as of ''Triple Deluxe''.
** Chef Kawasaki is affectionately referred to as "KWSK" in Japanese communities.
** ''VideoGame/KirbysDreamLand2'', ''VideoGame/KirbysDreamLand3'', and ''VideoGame/Kirby64TheCrystalShards'' are collectively known as the "Dark Matter Trilogy" due to the three games having Dark Matter as the main villain(s). All three games were directed by Shinichi Shimomura instead of series creator Masahiro Sakurai (who directed all other non-spinoff games in the series prior to his departure post-''Air Ride''), and have more of a focus on puzzle solving rather than combat. Other similarities these games share include:
*** Having no traces of Meta Knight whatsoever.
*** [[spoiler:Having King Dedede be possessed by Dark Matter then fighting him.]]
*** Having some form of Copy Ability mixing system.
*** Having a true final boss only accessed by collecting all of a certain collectible, which then form a weapon used to combat said boss.
* GodNeverSaidThat:
** A portion of fans claim that Kirby is meant to be genderless, citing a supposed ''Smash Bros.'' Q & A where Masahiro Sakurai said so. However, this is mainly the result of miscommunication, as the interview in question simply had Sakurai joking about Kirby being female.
** Current series director Shinya Kumazaki made the [[BrokenBase extremely controversial]] confirmation that The Arena and the Extra Modes are AlternateContinuity side-stories, which some fans interpreted as "Galacta Knight's existence is non-canon".
** The longstanding belief that Dark Matter is a WoobieDestroyerOfWorlds who can't feel positive emotions did not come from any WordOfGod source, but rather from an outsourced Japanese player's guide, making it WordOfSaintPaul at best.
* KeepCirculatingTheTapes: ''Kirby Tilt [='n'=] Tumble'' is one of the very few Kirby games that has not received a digital re-release on the Virtual Console, and ''Kirby Super Star Ultra'' is the only DS ''Kirby'' game that has not been released on the Wii U Virtual Console.
* NewbieBoom:
** While it didn't make a CashCowFranchise out of the series the same way the Pokemon anime did, quite a few Kirby fans will admit the anime for the games, ''Anime/KirbyRightBackAtYa'', is what introduced them to the series and it shows. The anime still maintains a dedicated following to this day. So much so that, since its conclusion, HAL has brought [[CanonImmigrant various things from the show into the games]] and even included several of its episodes in ''Kirby's Dream Collection: Special Edition'' which celebrated the series' 20th anniversary.
** The ''VideoGame/SuperSmashBros'' games also cause this, as Kirby is one of the central characters in each game, and is also one of the most popular characters for his character-based Copy Abilities and multiple floaty jumps. Lots of players become enamored with the pink puffball, which raises visibility and sales for his own games. This was taken even further when Meta Knight and King Dedede were added in ''Brawl'', each bringing their unique personalities and abilities to the fray and providing different perspectives on Kirby's universe.
** ''VideoGame/KirbyPlanetRobobot'' also resulted in an influx of newcomers to the series thanks to positive reception and word-of-mouth, interestingly despite the game being much more continuity-based than previous titles.
* NoExportForYou:
** The Super NES version of ''Kirby's Star Stacker'' never got released outside of Japan[[note]]Where both versions are known as "Kirby no Kirakira Kids" (lit. "Kirby's Twinkling Kids").[[/note]] due to being released there in 1998, '''two years''' after the Nintendo 64's release and one year after the SNES's discontinuation in North America.
** Conversely, ''Kirby's Avalanche'' never got released in Japan, since it was just a DolledUpInstallment of ''[[VideoGame/PuyoPuyo Super Puyo Puyo Tsu]]''.
** For lesser-known reasons, the 20th anniversary compilation-game ''Dream Collection'' didn't get a Europe or Australian release.
* PermanentPlaceholder: Kirby was originally just programmed in to develop the game around him and come up with a character design later on, but then the developers began to grow attached to the [[WaddlingHead cute little blob]], and the design was decided as final.
* ShrugOfGod: The official word on whether Ado and Adeleine (officially spelled in Japanese as "'''Ado'''rehnu") are the same character with two different names was "probably" for the longest time. The Japanese 25th anniversary booklet [[https://twitter.com/roselii49/status/940478645268766720 eventually revealed]] the two are the same character.
* ThrowItIn: Kirby's appearance was originally intended to be a placeholder.
* TropeNamer: This series named the following tropes:
** AmericanKirbyIsHardcore
** BubblyClouds
** DreamLand
** FountainOfMemes (after the Fountain of Dreams)
* UrbanLegendOfZelda: In the late 2000s, there were a bevy of FanWank all centered around "plot elements" that allegedly [[LostInTranslation only existed in the Japanese versions of the games]]. Most of these centered around Dark Matter being TheManBehindTheMan to just about every ''Kirby'' villain under the sun, with a particularly notorious one claiming Dark Matter was present in ''VideoGame/KirbyCanvasCurse'' and gave Drawcia her powers via DealWithTheDevil becoming widespread enough that it had to be wiped from this very Wiki several times. Funnily enough, some concept art later revealed Dark Matter (along with Nightmare) really ''was'' going to be in ''Canvas Curse'' albeit as a playable character rather than a boss, making it an ''enemy'' of Drawcia rather than an ally as the rumor claimed.
* WhatCouldHaveBeen:
** During ''Kirby's Dream Land's'' development, Creator/ShigeruMiyamoto was under the impression that Kirby was yellow (due to the game's monochrome sprites leaving room for interpretation). He expressed surprise to Creator/MasahiroSakurai when he saw the game's box art, which depicted Kirby as pink. However, to honor Miyamoto's suggestion, yellow Kirby is usually the [[ColorCodedMultiplayer second player]] [[PaletteSwap palette swap]] for Kirby in his multiplayer appearances, including the ''VideoGame/SuperSmashBros'' series.
** Kirby was intially a placeholder dummy character until the team figured out more advanced characters to consider as protagonists for ''Kirby's Dream Land'', but they came to like the little guy so much that they decided to keep him in. The game was also called "Twinkle Popo" at one point, with Kirby himself being named Popopo.
** Unused sprites reveal that Kirby was going to have a shrinking ability in ''Kirby's Adventure'', but it was scrapped. The mechanic was later used in ''Kirby & The Amazing Mirror'' as the Mini ability. [[http://shmuplations.com/kirbysadventure/ An interview]] in the Japanese strategy guide for ''Adventure'' also revealed there were over 40 Copy Abilities at one point of development, including a rocket (implemented as Missile in ''Amazing Mirror''), an Animal ability for scratching and biting enemies (implemented in ''Kirby Squeak Squad''), and block creation (which gets used in another HAL Laboratory game, Videogame/BoxBoy).
** In an interview promoting the release of the [[UsefulNotes/SuperNintendoEntertainmentSystem Super NES Classic Edition]], Masahiro Sakurai revealed that there was one more subgame planned for ''VideoGame/KirbySuperStar'' called "''Kagero no Yakata''" (lit. Heat Haze Mansion). In it, Kirby was cursed with a mouth-sealing spell, so he had to explore a HauntedHouse in order to find a cure. Without being able to inhale, Kirby had to find other methods to obtain Copy Abilities, such as touching a candle to get Fire. The subgame was deemed low-priority, however, and had little to no work to show for it.
** Kirby, with the addition of a pink, curly hair on his head, was originally supposed to star in a SpinoffBabies game, ''Kid Kirby'', for the SNES; it was never finished, and all that remains of the game now are a few sprites and one stage layout.
** When the Nintendo 64 was in development and still called the Ultra 64, one title in development was ''Kirby Bowl 64'' -- ''Kirby Bowl'' being the Japanese name for ''Kirby's Dream Course''. The snowboarding mode it featured likely led to ''Kirby's Air Ride''.
** ''Kirby Air Ride'' began on the Nintendo 64 and was scheduled for a late 1996 release. It went through years of delays until it was quietly cancelled in 1998. It caught the public by surprise when a [=GameCube=] version was announced in 2003. In addition, it was supposed to have a multi-themed star shaped track, but that got scrapped due to time constraints. It was also supposed to have a much bigger City Trial; the project was really ambitious even then.
** In ''Kirby 64: The Crystal Shards'', Waddle Dee, Adeleine, and King Dedede were meant to be individually playable; in the final game, only the latter remains playable, being ridden by Kirby in short sections. There is also evidence suggesting that all of the animal friends from ''Kirby's Dream Land 3'' were intended to reappear in significant capacity, as all three of their themes appear in-game[[note]]"Friends 1" only appears in the sound test, "Friends 2" is used as the Theater theme, and "Friends 3" is used as a level theme[[/note]] and they have DummiedOut HUD artwork.
** ''Kirby Tilt 'n' Tumble'' was almost re-branded as a ''Franchise/{{Pokemon}}'' game outside of Japan.
** Also, ''Kirby Tilt 'n' Tumble 2'' for the [=GameCube=], using the UsefulNotes/GameBoyAdvance and cable to control the same way as the original title.
** [[https://www.youtube.com/watch?v=yy2l5BSBSL0 There was originally supposed to be a Kirby platformer for the [=GameCube=], but it never got released.]] According to [[http://www.nintendo.co.jp/wii/interview/sukj/vol1/index.html this interview]], there were ''three'' unsuccessful attempts at making a home console ''Kirby'' game before ''VideoGame/KirbysReturnToDreamLand'', the fourth attempt that finally brought it out of DevelopmentHell. The 3D structure of the second attempt resurfaced in ''Kirby 3D Rumble'' (and, by extension, ''VideoGame/KirbysBlowoutBlast''; the use of abilities in that structure wouldn't be revisited until ''VideoGame/KirbyBattleRoyale''), and ''Videogame/KirbyStarAllies'' shows the return of Helpers (and, to a lesser extent, the Cleaning ability) from the well-known first attempt. The third attempt - a cel-shaded 2D game with upgradable abilities - has yet to be revisited.
** ''Kirby's Epic Yarn'' was supposed to not be a Kirby game (it has a different developer), its working name being "Fluff's Yarn" (with Prince Fluff as the main character). Out of fear that the project not turning out as well as planned, Nintendo suggested adding Kirby.
** The art book bundled with ''Kirby's Dream Collection: Special Edition'' includes unused character designs for some of the characters. Most notable is Meta Knight with red and black [[http://25.media.tumblr.com/tumblr_m7xuylJqjO1ra4czto1_500.jpg butterfly wings]], rather than his purple bat wings. [[spoiler:This design is reused into "Morpho Knight" in the bonus mode in ''VideoGame/KirbyStarAllies''.]]
** As seen in the 25th anniversary "''Kirby Art & Style Collection''" art book, Magolor's design went through several revisions, including one that inspired [[https://78.media.tumblr.com/4990c2a9b4fc1266f297a2cf6b3d622b/tumblr_inline_oyspa1yViz1sheea2_500.png Haltmann]] and one depicted as a [[https://78.media.tumblr.com/262a3a5e2b998f19b81be425033fa41d/tumblr_inline_oystwqSaeT1sheea2_500.png girl]].
