At that moment Sora obtained a weapon called the Keyblade that allows him to fight creatures called Heartless, before ending up in another world, Traverse Town, where he meets [[Donald Duck]] and [[Goofy]], two emissaries from Disney Castle sent to find the Keyblade wielder under orders from their missing king.<ref name="KHgamespy">{{cite web| url = http://ps2.gamespy.com/playstation-2/kingdom-hearts/540394p1.html| title = Kingdom Hearts Review (PS2)| author = Turner, Benjamin| date = September 3, 2002| publisher = [[GameSpy]]| access-date = July 5, 2007| archive-date = January 21, 2012| archive-url = https://web.archive.org/web/20120121204211/http://ps2.gamespy.com/playstation-2/kingdom-hearts/540394p1.html| url-status = live}}</ref><ref name="MickeyNote">{{cite video game| title = Kingdom Hearts| developer = Square | publisher = Square Electronic Arts | date= November 15, 2002 |platform= PlayStation 2|quote='''King Mickey's Note:''' Donald, Sorry to rush off without sayin' goodbye, nevertheless, there's big trouble brewin'.

Though Sora defeats Ansem, he is forced to trap Riku and Mickey in the Realm of Darkness after sealing the door and resolute to find them while Kairi remains at the Destiny Islands for their return.

In ''Kingdom Hearts: Chain of Memories'', Sora's search for Riku and Mickey leads his group to Castle Oblivion,<ref name="COM-StrategyGuide">{{cite book| last= Hollinger| first= Elizabeth| year = 2004| title = Kingdom Hearts: Chain of Memories Official Strategy Guide| publisher = [[BradyGames]] Publishing| isbn= 0-7440-0473-X| oclc= 122414850}}</ref> a fortress controlled by a mysterious group of non-existent "[[Universe of Kingdom Hearts#Nobody|Nobodies]]" called [[Organization XIII]], the castle's overseer Marluxia using the power of a girl named [[Naminé]] to alter the group's memories for his agenda.

Finding the comatose Sora while joining forces with the mysterious [[Characters of Kingdom Hearts#Ansem the Wise|DiZ]], Riku helps Naminé keep his friend safe until he is awoken. In ''Kingdom Hearts 358/2 Days'', a snag in the plan over the year forces Riku to capture [[Roxas (Kingdom Hearts)|Roxas]]—Sora's Nobody and Organization XIII member that came into being when Sora briefly became a Heartless in the first game-after he was forced to defeat and absorb Xion, a Replica of Sora in Kairi's image.

In ''Kingdom Hearts II'', after Roxas was integrated back into him, an awakened Sora and his friends resume their search for Riku and King Mickey, the latter's mentor [[Characters of Kingdom Hearts#Yen Sid|Yen Sid]] re-familiarizing the trio with the Nobodies and Organization XIII's remaining members whom they deal alongside Maleficent and her right hand [[Pete (Disney)|Pete]].

Axel, a rogue Organization member who is Roxas' friend and first encountered Sora in Castle Oblivion, abducts Kairi in an attempt to see Roxas. Axel's action only give Saix, his former friend and Xemnas' enforcer, leverage to force Sora into finishing what Roxas and Xion began. Axel sacrifices himself to help Sora's group reach The World That Never Was (Organization XIII's headquarters) and, after defeating Xemnas's right hand Xigbar, reunite with Riku and Kairi. DiZ, revealed to be the real Ansem, attempts dissipating some of the artificial Kingdom Hearts before being engulfed in an explosion when his extraction device self-destructs and is sent to the Realm of Darkness.<ref>{{cite video game|title=Kingdom Hearts II|developer=Square Enix|publisher=Square Enix U.S.A., Buena Vista Games |date=March 28, 2006 |platform=PlayStation 2|quote='''Ansem the Wise:''' It's a device to reclaim Kingdom Hearts and encode it as data. / '''Mickey:''' Not sure I get it. / '''Ansem the Wise:''' I do not claim to know the outcome of this venture, either.

During their exchange, it mistook Sora for Xehanort, after which Sora fought the mysterious armour. Sora won the battle, and the Lingering Will merely knelt down after this, saying that he once felt the power Sora possessed.

Sometime later after the events of the game, Sora, Riku, and Kairi receive a letter from King Mickey. The letter, written by Mickey during the events of ''Kingdom Hearts Coded'', describes the parts of their past that Naminé learned while restoring Sora's memory.<ref>{{cite video game|title=Kingdom Hearts Re:coded|developer=Square Enix, h.a.n.d.|publisher=Square Enix|date=January 11, 2011 |platform=Nintendo DS|quote='''Data-Naminé''': It all began with these memories that were sleeping way down deep in Sora's heart. / '''Data-Sora''': These are my memories? / '''Data-Naminé''': No. Not yours.

[...] When I first found them while repairing your memory, I thought I'd made a mistake.}}</ref> As they read the letter, they learn of [[Xehanort]]'s true identity as a Keyblade Master who sought the secrets of the Keyblade War which created their current reality and the fates that befall the apprentices of his friend Eraqus during the events of ''Kingdom Hearts Birth by Sleep'': [[Terra (Kingdom Hearts)|Terra]] having ended up possessed by Xehanort and made into the original being that Xehanort's Heartless and Xemnas were split from; [[Ventus (Kingdom Hearts)|Ventus]] sacrificing his heart by fighting his dark counterpart Vanitas, while trying to prevent Xehanort from recreating the legendary [[Universe of Kingdom Hearts#χ-blade|χ-blade]] which allows the user to control Kingdom Hearts, and hiding within four-year-old Sora's heart; and new Keyblade Master [[Aqua (Kingdom Hearts)|Aqua]] trapped within the Realm of Darkness while an amnesic Xehanort ended up Ansem's apprentice alongside his accomplice Braig (Xigbar's original self).<ref>{{cite video game|title=Kingdom Hearts 3D: Dream Drop Distance|developer=Square Enix 1st Production Department|publisher=Square Enix|date=July 31, 2012|platform=Nintendo 3DS|quote='''Xehanort''': Ah, but destiny is never left to chance. I merely guided them to their proper places.

But his two halves are gone. There was Ansem, who commanded the Heartless...and Xemnas, who commanded the Nobodies. Didn't Sora defeat them both? / '''Yen Sid:''' Correct, those two met their end. However, therein lies exactly our problem. Their destruction now guarantees the original Xehanort's reconstruction. /.../ In short...this means Master Xehanort will return.}}</ref> To combat the new threat Xehanort poses, Sora and Riku take an exam to attain the Mark of Mastery that will allow them to become Keyblade Masters themselves.<ref>{{cite video game|title=Kingdom Hearts Re:coded|developer=Square Enix, h.a.n.d.|publisher=Square Enix|date=January 11, 2011 |platform=Nintendo DS|quote='''Yen Sid:''' Mickey, please summon Sora hither.

During the test in ''Kingdom Hearts 3D: Dream Drop Distance'', Sora and Riku enter the Realm of Sleep where they encounter a young version of Xehanort who can travel through time.<ref>{{cite video game|title=Kingdom Hearts 3D: Dream Drop Distance|developer=Square Enix 1st Production Department|publisher=Square Enix|date=July 31, 2012|platform=Nintendo 3DS|quote='''Young Xehanort:''' I am Xehanort from the most distant past.

Your seven lights just like my thirteen darknesses, whose final clash will beget the prize I seek— / '''Xehanort and Mickey''': The χ-blade!}}</ref> Sora is narrowly saved from being Xehanort's final vessel with the aid of Lea (Axel's original self) and Riku learns about data that Ansem the Wise had implanted within Sora during his year-long sleep, which may be used to save those connected to Sora.<ref>{{cite video game|title=Kingdom Hearts 3D: Dream Drop Distance|developer=Square Enix 1st Production Department|publisher=Square Enix|date=July 31, 2012|platform=Nintendo 3DS|quote='''Ansem the Wise''': Perhaps I wanted to atone for events of the past, even if no apology can undo the harm I have wrought. I felt...that I ought to leave at least something behind. So I digitized myself and my research, and hid them within Sora. /.../ He has touched countless hearts, he has accepted them, and he has saved them. And some of those hearts have never left him—whether they fell into darkness or were trapped there—whether they sleep in the darkness of Sora's heart, or were welcomed into its warmth--they can be saved. All Sora needs to do is be himself and follow wherever it is that his heart takes him. It is the best and the only way. The rest is in there.}}</ref> At the end of the exam, Riku is declared a Keyblade Master;<ref>{{cite video game|title=Kingdom Hearts 3D: Dream Drop Distance|developer=Square Enix 1st Production Department|publisher=Square Enix|date=July 31, 2012|platform=Nintendo 3DS|quote='''Yen Sid''': I believe we need a new Keyblade Master, one with a new kind of power. Sora and Riku, you both deserve the honor. However, one of you braved the realm of sleep again to unlock the final Keyhole and save a friend. Riku, I name you our new true Keyblade Master.}}</ref> in ''Kingdom Hearts HD 2.8 Final Chapter Prologue'', Sora embarks on another journey to regain his "Power of Waking" while Riku helps Mickey find Aqua, Yen Sid training Kairi and Lea so they can help in the final battle against Xehanort and keep him from the Princesses of Heart.<ref>{{cite video game|title=Kingdom Hearts 3D: Dream Drop Distance|developer=Square Enix 1st Production Department|publisher=Square Enix|date=July 31, 2012|platform=Nintendo 3DS|quote='''Yen Sid''': [Even] if we deliberately avoid finding our seven lights to avert another Keyblade War, Xehanort will still target the seven princesses in order to forge the χ-blade. [...] To protect the seven pure hearts, we will need seven lights strong enough to stand against the thirteen darknesses.}}</ref>

In ''Kingdom Hearts III'', Sora regains his "Power of Waking" in his group's travels while Riku and Mickey retrace Aqua's steps to find her and Terra. Sora later discovers Eraqus's Keyblade on the beach and uses it to open a door to the Realm of Darkness, finding Aqua who has been consumed by darkness after Ansem was abducted by Xehanort's Heartless. Once Aqua is purified by Sora and Riku, she leads them to Castle Oblivion which she restores to its true form as the Land of Departure to revive Ventus despite Vanitas' interference. The group are joined by Kairi and Lea as they face Xehanort and his followers, with a Riku Replica completing the group, at the Keyblade Graveyard. After initially losing the fight, Sora once again uses the "Power of Waking" to restore the guardians and call upon the "Lingering Will" armour, to assist in the fight. Afterwards it is revealed that Saix and Vexen sabotaged the Organization's plan by restoring Roxas as Sora's group manage to defeat all of Xehanort's remaining selves while freeing Xion and Terra from his control. Xehanort kills Kairi to force Sora to manifest the χ-blade, revealing his true plan is to use the true Kingdom Hearts to wipe the slate on reality clean before finally being defeated. Xehanort departs with Eraqus's spirit into the light as Sora closes Kingdom Hearts. Sora also sacrifices himself by using the "Power of Waking" once more to revive Kairi. Sometime later, all the guardians, including their close friends and allies, celebrate victory at Destiny Islands. Xigbar, revealed to be the current incarnation of the ancient Keyblade Master Luxu from the time of the Keyblade War, summons the Foretellers, his fellow Keyblade Masters, to the present for the next phase of his mission. A year later, all attempts to find a clue to Sora's current whereabouts have proven to be futile until Riku and Kairi, with the help of the Fairy Godmother, find clues that lead them to believe that Sora has been transported outside of their reality. Riku embarks on a search for him after opening a portal to another reality in the Final World. Elsewhere, Sora meets Yozora, a supposedly fictional character from a video game. During their exchange Yozora claims that he is tasked to "save Sora" and the world is transported into Shibuya. Sora is challenged to a fight by Yozora, whom he defeats. Yozora fades away as Sora returns to The Final World. Both Sora and Yozora wonder if their meeting was real, with neither character making sense of it.

=== Gameplay ===
The ''Kingdom Hearts'' games contain elements of [[action game|action]] [[role-playing video game]]s with [[hack and slash|hack-and-slash]] elements. The games are driven by a linear progression from one story event to the next, usually shown in the form of a [[cutscene]], though there are numerous [[Quest (gaming)|side quests]] available that provide bonus benefits to the characters. In most games, the player primarily controls the principal protagonist of the series, [[Sora (Kingdom Hearts)|Sora]]. Sora is usually accompanied by Donald Duck and Goofy, who are [[Artificial intelligence (video games)|artificial intelligence-controlled]] [[Non-player characters|non-playable characters]] that aid Sora in battle. In the first and third game, their behavior can be altered to suit different combat objectives. The games feature real-time combat that incorporates physical attacks, magic, and summonings, though each game handles battles differently. The game also allows for items to be used on the field of battle to heal oneself or one's party members.

[[Kingdom Hearts (video game)#Gummi Ship|Gummi Ships]] are another common element of the series, which serve as the main mode of transportation between worlds in the games. The gameplay for the Gummi Ship sections is more akin to a [[Shoot 'em up|rail shooter]]. Because it received negative criticism in the first game, it was modified in the third game.<ref name="KHU-NI1UP">{{cite web|url=http://www.kh2.co.uk/?page=NI/1UP-2 |title=1UP – E3 2005 Interview |publisher=Kingdom Hearts Ultimania |access-date=August 31, 2007 |archive-url=https://web.archive.org/web/20070808165059/http://www.kh2.co.uk/?page=NI%2F1UP-2 |archive-date=August 8, 2007 |url-status=dead }}</ref> Most games also feature a journal which is accessible from the main menu. This journal keeps track of information regarding the story, characters, enemies, and locations. In ''Kingdom Hearts'', ''Chain of Memories'', ''Kingdom Hearts II'', and ''Kingdom Hearts III'', the journal is kept by [[Jiminy Cricket]], who was appointed by [[Minnie Mouse|Queen Minnie]] as the royal chronicler.<ref>'''Minnie:''' Oh, and to chronicle your travels, he will accompany you. / '''Jiminy:''' Over here! Cricket’s the name. Jiminy Cricket, at your service. {{cite video game| title = Kingdom Hearts| developer = Square | publisher = Square Electronic Arts | date= November 15, 2002 |platform= PlayStation 2}}</ref> In ''358/2 Days'', ''Birth by Sleep'', and ''Dream Drop Distance'', the main characters write their own journal entries.

[[File:Kingdom Hearts Battle Screenshot.png|thumb|A battle in the first ''Kingdom Hearts'' game]]
The games are influenced by their parent franchise, ''[[Final Fantasy]]'',<ref>{{Cite magazine |date= July 2007|title= Tetsuya Nomura Interview|magazine= [[Edge (magazine)|Edge]]|publisher= [[Future Publishing]]|issue= 177|pages= 80–81}}</ref> and carry its gameplay elements over into their own action-based, [[hack and slash|hack-and-slash]] system. Like many traditional role-playing games, ''Kingdom Hearts'' features an [[experience point]] system which determines character development. As enemies are defeated, the player gains experience which culminates in a "level-up", where the characters grow stronger and gain access to new [[Skill (role-playing games)|abilities]].<ref name="Instructions">{{cite book | author = Square | year = 2002 | title = ''Kingdom Hearts'' Instruction Booklet | publisher = Square | author-link = Square (video game company)}}</ref> The amount of experience is shared with all party members and each character grows stronger as experience is gained.<ref name="KHgamespot">{{cite web| url = https://www.gamespot.com/reviews/kingdom-hearts-review/1900-2879719/| archive-url = https://web.archive.org/web/20070502033747/http://www.gamespot.com/ps2/adventure/kingdomhearts/review.html| archive-date = 2007-05-02| website = [[GameSpot]]| title = ''Kingdom Hearts'' for PlayStation 2 Review| author = Greg Kasavin| date = September 9, 2002| access-date = May 13, 2007}}</ref>

=== Music ===
{{Further|Music of Kingdom Hearts}}
The music for the series has been primarily composed by [[Yoko Shimomura]].

While the themes for some of the Disney-based worlds are taken directly from their Disney film counterparts,<ref name="KHII-OST"/> most of them are given entirely original musical scores. In addition to each world having unique background music, each is given its own battle theme rather than having a common theme to cover all fights. Several of the main characters have themes, and the final boss of each game has several themes played in the various phases of those fights. The fights with [[Sephiroth (Final Fantasy)|Sephiroth]] feature a modified version of [[Nobuo Uematsu]]'s "[[One-Winged Angel]]" from ''[[Final Fantasy VII]]''.<ref name="OST-Box"/>

The main [[theme song]]s for the ''Kingdom Hearts'' games were written and performed by Japanese pop star, [[Hikaru Utada]].

The initial idea for ''Kingdom Hearts'' began with a discussion between [[Shinji Hashimoto]] and [[Hironobu Sakaguchi]] about ''[[Super Mario 64]]''.<ref name="KH3DIwata">{{cite web |title=Iwata Asks |url=http://iwataasks.nintendo.com/interviews/#/3ds/creators/11/0 |url-status=dead |archive-url=https://web.archive.org/web/20150725233103/http://iwataasks.nintendo.com/interviews/#/3ds/creators/11/0 |archive-date=July 25, 2015 |access-date=March 4, 2013 |publisher=Iwataasks.nintendo.com}}</ref> They were planning to make a game with freedom of movement in three dimensions like ''Super Mario 64'' but lamented that only characters as popular as Disney's could rival a ''Mario'' game. Tetsuya Nomura, overhearing their conversation, volunteered to lead the project and the two producers agreed to let him direct.<ref name="KH3DIwata"/> A chance meeting between Hashimoto and a Disney executive in an elevator (Square and Disney previously shared the same building in Japan) allowed Hashimoto to pitch the idea directly to Disney.<ref>{{cite video| date=October 10, 2007| url=http://www.gametrailers.com/videos/view/gt-retrospectives/100442-Final-Fantasy-Retrospective-Part-XI| title=Final Fantasy Retrospective Part XI| medium=GameTrailers.com feature| publisher=[[GameTrailers]]| access-date=November 20, 2007}}</ref><ref name="IGN-TGS04-NI">{{cite web| website = IGN| title = TGS 2004: Tetsuya Nomura Q&A| url = https://www.ign.com/articles/2004/09/23/tgs-2004-tetsuya-nomura-qa| author = Anoop Gantayat| date = September 23, 2004| access-date = June 12, 2007| archive-date = November 6, 2012| archive-url = https://web.archive.org/web/20121106054807/http://www.ign.com/articles/2004/09/23/tgs-2004-tetsuya-nomura-qa| url-status = live}}</ref> Development began in February 2000 with Nomura as director and Hashimoto as producer.<ref>{{cite web| url = https://ffx.sakura.ne.jp/kh.htm| title = Kingdom Hearts キングダム ハーツ| publisher = Final Fantasy 2000| language = ja| access-date = May 30, 2007| archive-url = https://web.archive.org/web/20120105154015/http://ffx.sakura.ne.jp/kh.htm| archive-date = January 5, 2012| url-status = dead}}</ref> While Nomura had done previous work in the ''Final Fantasy'' series as monster designer and graphic director, he did not gain widespread recognition until he was the lead character designer for ''[[Final Fantasy VII]]''. ''Kingdom Hearts'' marked his transition into a directorial position, though he also served as the game's character designer. Scenarios were provided by [[Kazushige Nojima]] who was a scenario writer for Square from ''Final Fantasy VII'' until he left in 2003. Originally the development focused on the gameplay with a simple story to appeal to Disney's target age range. After ''Kingdom Hearts'' executive producer Hironobu Sakaguchi told Nomura the game would be a failure if it did not aim for the same level as the ''Final Fantasy'' series, he began to develop the story further.<ref name="Insider-KHU-NI">{{cite web |url=https://www.khinsider.com/content/view/42/41/ |archive-url=https://web.archive.org/web/20120205212633/http://www.khinsider.com/content/view/42/41 |archive-date=February 5, 2012 |title=KHU Interview w/Tetsuya Nomura |publisher=Kingdom Hearts Insider |access-date=August 10, 2007 |url-status=dead }}</ref> In June 2013, Nomura stated the name of the game came from him thinking about [[Walt Disney Parks and Resorts|Disney Theme Parks]], especially [[Disney's Animal Kingdom|Animal Kingdom]]. However, Nomura could not get the [[Intellectual property|IP]] with just "Kingdom", so the development team began to think about "heart" as a core part of the story, so they decided to combine the two to form "Kingdom Hearts".<ref>{{cite web|url=https://www.gamezone.com/news/tetsuya-nomura-discusses-kingdom-hearts-1-5-kingdom-hearts-3-and-final-fantasy-15/|title=Tetsuya Nomura discusses Kingdom Hearts 1.5, Kingdom Hearts 3 and Final Fantasy 15|last=Splechta|first=Mike|publisher=Gamezone|date=June 26, 2013|access-date=June 28, 2013|archive-date=October 23, 2014|archive-url=https://web.archive.org/web/20141023135351/http://www.gamezone.com/news/tetsuya-nomura-discusses-kingdom-hearts-1-5-kingdom-hearts-3-and-final-fantasy-15|url-status=live}}</ref><ref>{{cite AV media|url=https://www.youtube.com/watch?v=IpzjiMPhNBU| archive-url=https://ghostarchive.org/varchive/youtube/20211114/IpzjiMPhNBU| archive-date=2021-11-14 | url-status=live|title=Square Enix Presents E3 2013 – Day1 [#03] – KINGDOM HEARTS HD 1.5 ReMIX Interview|author=Square Enix|publisher=Youtube|date=June 25, 2013|access-date=June 28, 2013}}{{cbignore}}</ref>

Nomura placed a secret trailer in ''Kingdom Hearts'' in hopes that fans would want a sequel. He was unsure if fans would want a sequel and felt that if they did not, then it would be best to leave certain events in the first game unexplained.<ref name="KH-NI-KHIIU">{{cite web|title=Kingdom Hearts II Ultimania – Tetsuya Nomura Interview |url=http://www.kh2.co.uk/?page=NI/KH2U |publisher=Kingdom Hearts Ultimania |access-date=August 10, 2007 |archive-url=https://web.archive.org/web/20070710094227/http://www.kh2.co.uk/?page=NI%2FKH2U |archive-date=July 10, 2007 |url-status=dead }}</ref> After ''[[Kingdom Hearts Final Mix]]'' was completed, development for ''Kingdom Hearts II'' began.<ref name="GS-NI-Dengeki">{{cite web| author = GameSpot staff| website = [[GameSpot]]| url = https://www.gamespot.com/ps2/rpg/kingdomhearts2/news.html?sid=6076646| date = October 10, 2003| title = ''Kingdom Hearts'' II's Tetsuya Nomura Q & A| access-date = June 15, 2007|archive-url=https://web.archive.org/web/20110525055139/http://www.gamespot.com/ps2/rpg/kingdomhearts2/news.html?sid=6076646|archive-date=May 25, 2011}}</ref> There were several obstacles to clear before development could begin on a sequel. One was the development team's desire to showcase Mickey Mouse more;<ref name="KH-NI-KHIIU"/> Mickey's inclusion in the first game was restricted to a very small role.<ref name="Insider-KHU-NI"/> Nomura had planned for the sequel to take place a year after the first and originally intended for the events of that year to be left unexplained. To bridge the gap between the two games, ''Kingdom Hearts: Chain of Memories'' was developed.<ref name="KH-COMgamespy">{{cite web| url = http://gba.gamespy.com/gameboy-advance/kingdom-hearts-chain-of-memories/571890p1.html| author = Raymond Padilla| date = December 8, 2004| publisher = [[GameSpy]]| title = Kingdom Hearts: Chain of Memories Review| access-date = May 23, 2007|archive-url=https://web.archive.org/web/20121107091957/http://gba.gamespy.com/gameboy-advance/kingdom-hearts-chain-of-memories/571890p1.html|archive-date=November 7, 2012}}</ref> Nomura was hesitant about releasing a game on the [[Game Boy Advance]] because he felt the 3D graphics of the original game would not translate well into 2D.

=== Creation and design ===
Though Disney gave Nomura freedom in the characters and worlds used for the games, he and his staff tried to stay within the established roles of characters and boundaries of the worlds.<ref name="NI-TechTV">{{cite web|url=http://www.kh2.co.uk/?page=NI/TechTv |title=Nomura Interview TechTv |publisher=Kingdom Hearts Ultimania |access-date=July 18, 2007 |archive-url=https://web.archive.org/web/20070609050907/http://www.kh2.co.uk/?page=NI%2FTechTv |archive-date=June 9, 2007 |url-status=dead }}</ref> Nomura has stated that though many of the Disney characters are not normally dark and serious, there were not many challenges making them so for the story and despite this, their personalities shine because they maintain their own characteristics.<ref name="NI-PS.comEur">{{cite web|title=Playstation.com Europe – E3 Interview |url=http://www.kh2.co.uk/?page=NI/Playstation |publisher=Kingdom Hearts Ultimania |access-date=September 20, 2007 |archive-url=https://web.archive.org/web/20070418212412/http://www.kh2.co.uk/?page=NI%2FPlaystation |archive-date=April 18, 2007 |url-status=dead }}</ref> He also felt managing and keeping multiple worlds was problematic.<ref name="NI-IGN">{{cite web|url=http://www.kh2.co.uk/?page=NI/IGN |title=IGN – Nomura Interview |publisher=Kingdom Hearts Ultimania |access-date=August 2, 2007 |archive-url=https://web.archive.org/web/20070608022106/http://www.kh2.co.uk/?page=NI%2FIGN |archive-date=June 8, 2007 |url-status=dead }}</ref> When deciding which worlds to include in the game, the development staff tried to take into account worlds with Disney characters that would be interesting and made an effort to minimize any overlap in the overall look and feel of each world.<ref name="Insider-KHU-NI"/><ref name="KHII-TN-interview">{{cite web| url = https://www.videogamesblogger.com/2006/08/11/kingdom-hearts-ii-tetsuya-nomura-interview.htm| title = Kingdom Hearts II Tetsuya Nomura interview| date = August 11, 2006| publisher = Video Game Blogger| access-date = July 21, 2007| archive-date = August 11, 2007| archive-url = https://web.archive.org/web/20070811031613/http://www.videogamesblogger.com/2006/08/11/kingdom-hearts-ii-tetsuya-nomura-interview.htm| url-status = live}}</ref>

The inclusion of specific ''Final Fantasy'' characters was based on the opinions of both fans and staff.<ref name="RPGamer-NI">{{cite web| author=Boulette, Bryan| url=https://rpgamer.com/news/Q4-2005/112705b.html| publisher=RPGamer| title=Nomura Divulges Kingdom Hearts II Details| access-date=July 23, 2007| date=November 27, 2005| url-status=dead| archive-url=https://web.archive.org/web/20120403035424/http://www.rpgamer.com/news/Q4-2005/112705b.html| archive-date=April 3, 2012| df=mdy-all}}</ref> Another criterion for inclusion was whether the staff felt the characters would fit into the storyline and in the ''Kingdom Hearts'' universe.<ref name="NI-1UP-1">{{cite web|title=Tetsuya Nomura 1st 1UP Interview |url=http://www.kh2.co.uk/?page=NI/1UP-1 |publisher=Kingdom Hearts Ultimania |access-date=September 20, 2007 |archive-url=https://web.archive.org/web/20070610203227/http://www.kh2.co.uk/?page=NI%2F1UP-1 |archive-date=June 10, 2007 |url-status=dead }}</ref> Initially, Nomura was hesitant to use characters he did not design, because he was unfamiliar with the backstory of such characters.<ref name="KH-NI-Dengeki2">{{cite web|url=http://www.kh2.co.uk/?page=NI/Dengeki-2 |publisher=Kingdom Hearts Ultimania |title=Dengeki – Kingdom Hearts 2 Progress Report |access-date=July 27, 2007 |archive-url=https://web.archive.org/web/20070608020051/http://www.kh2.co.uk/?page=NI%2FDengeki-2 |archive-date=June 8, 2007 |url-status=dead }}</ref> For ''Kingdom Hearts II'', he changed his mind after receiving pressure from his staff.<ref name="RPGamer-NI"/> Throughout the development of the games, Nomura has often left certain events and connections between characters unexplained until the release of future games. Nomura does this because he feels that games should have room for fans to speculate and use their imagination. He has stated that with speculation, even though a game gets old, people can still be happy with it.<ref name="KH-NI-KHIIU"/>

=== Promotion ===
The first ''Kingdom Hearts'' was announced at [[E3 (Electronic Entertainment Expo)|E3]] in May 2001.<ref name="GS-CompanyLine"/> Initial details were that it would be a collaboration between Square and [[Disney Interactive]], and would feature worlds developed by both companies and Disney characters. New characters were designed by Nomura and include Sora, Riku, Kairi, and the Heartless.<ref name="GS-CompanyLine"/><ref name="GS-E3-2001">{{cite web | url = https://www.gamespot.com/ps2/adventure/kingdomhearts/news.html?sid=2761861| author = Gerstmann, Jeff | date=May 17, 2001| website = [[GameSpot]]| title = E3 2001: Square announces Disney RPG for PS2| access-date=January 23, 2008|archive-url=https://web.archive.org/web/20110628212836/http://www.gamespot.com/ps2/adventure/kingdomhearts/news.html?sid=2761861|archive-date=2011-06-28}}</ref> On May 14, 2002, a press release announced a list of the English voice actors. The list included [[Haley Joel Osment]], [[David Gallagher]], and [[Hayden Panettiere]] as the three new characters introduced into the game. It was also announced that many of the Disney characters would be voiced by the official voice actors from their respective Disney films.<ref name="GS-CompanyLine"/><ref>{{cite web| url = https://www.ign.com/articles/2002/05/14/kingdom-hearts-voice-cast| author = IGN Staff| website = IGN| title = IGN: Kingdom Hearts Voice Cast| date = May 14, 2002| access-date = May 13, 2007| archive-date = September 19, 2018| archive-url = https://web.archive.org/web/20180919133831/https://www.ign.com/articles/2002/05/14/kingdom-hearts-voice-cast| url-status = live}}</ref>

A secret trailer in the first ''Kingdom Hearts'' and ''Kingdom Hearts Final Mix'' hinted at the possibility of a sequel. Rumors for a sequel on the PlayStation 2 were spurred in Japan when a Japanese video game site, Quiter, stated that "an internal (and anonymous) source at Square Japan" confirmed that development of ''Kingdom Hearts II'' had begun.<ref>{{cite web| url = https://www.ign.com/articles/2003/03/07/kingdom-hearts-2-on-ps2| title = Kingdom Hearts 2 on PS2?| website = IGN| author = IGN staff| date = March 7, 2003| access-date = June 14, 2007| archive-date = November 6, 2012| archive-url = https://web.archive.org/web/20121106125107/http://www.ign.com/articles/2003/03/07/kingdom-hearts-2-on-ps2| url-status = live}}</ref> It was not until ''Kingdom Hearts II'' was announced, along with ''Kingdom Hearts: Chain of Memories'', at the [[Tokyo Game Show]] in September 2003 that rumors were confirmed.<ref name="KH-Sequels-GS">{{cite web| author = Justin Calvert| website = [[GameSpot]]| title = TGS 2003: Kingdom Hearts sequels announced| url = https://www.gamespot.com/gba/rpg/kingdomheartschainofmemories/news.html?sid=6075893| date = September 26, 2003| access-date = June 8, 2007|archive-url=https://web.archive.org/web/20090518081555/http://www.gamespot.com/gba/rpg/kingdomheartschainofmemories/news.html?sid=6075893|archive-date=2009-05-18}}</ref> Initial details were that it would take place some time after ''Kingdom Hearts: Chain of Memories'', which takes place directly after the first game. Other details included the return of Sora, Donald, and Goofy, as well as new costumes. At the 2004 Square Enix E3 press conference, the producer, Shinji Hashimoto, stated that many mysteries of the first game would be answered.<ref>{{cite web |url=https://www.gaming-age.com/event/2004/e3/12-60 |archive-url=https://web.archive.org/web/20110605193508/http://www.gaming-age.com/event/2004/e3/12-60 |archive-date=June 5, 2011 |title=Square Enix E3 Press Conference and "Dear Friends" Concert |publisher=Gaming Age |date=May 12, 2004 |author=Benson, Mike |access-date=September 25, 2007 |url-status=dead }}</ref>

To help market the games, websites were set up for each game and demos were on display at gaming events. Each game in the main series was also re-released in Japan with additional content and served as [[canon (fiction)|canonical]] updates to the series.<ref>{{cite web| language = ja| title = 「キングダム ハーツII ファイナル ミックス」に新要素が!!| url = https://www.famitsu.com/game/coming/2007/03/23/104,1174620771,68873,0,0.html| publisher = [[Famitsu]]| date = March 24, 2007| access-date = July 6, 2007| archive-date = July 11, 2007| archive-url = https://web.archive.org/web/20070711104558/http://www.famitsu.com/game/coming/2007/03/23/104,1174620771,68873,0,0.html| url-status = live}}</ref> The additional content foreshadowed later plot elements in the series. The rereleases of the main series games had the term "Final Mix" added after the title, while ''Kingdom Hearts: Chain of Memories'' and ''Kingdom Hearts Coded'' were re-released as ''Kingdom Hearts Re:Chain of Memories'' and ''Kingdom Hearts Re:coded'' and released on the PlayStation 2 and Nintendo DS, respectively, with 3D graphics, voice overs during some cutscenes, and new game content.<ref>{{cite web| url = https://www.ign.com/games/kingdom-hearts-ii| title = Kingdom Hearts II Final Mix| website = IGN| access-date = June 21, 2007| archive-date = September 14, 2013| archive-url = https://web.archive.org/web/20130914062928/http://www.ign.com/games/kingdom-hearts-ii| url-status = live}}</ref><ref>{{cite web| url = http://www.play-asia.com/paOS-13-71-43-49-en-70-1xlx.html| publisher = Play-Asia| title = Kingdom Hearts II Final Mix+ (Limited Package Version)| access-date = June 21, 2007| archive-date = September 27, 2007| archive-url = https://web.archive.org/web/20070927003427/http://www.play-asia.com/paOS-13-71-43-49-en-70-1xlx.html| url-status = live}}</ref>

=== Printed adaptations ===
A [[manga]] based on the ''Kingdom Hearts'' storyline has been released in Japan and the United States. The story and art are done by [[Shiro Amano]], who is also known for his manga adaptation of the ''[[Legend of Mana]]'' video game. The story follows the events that took place in the video games with differences to account for the loss of interactivity a video game provides. The manga was originally serialized in Japan by Square Enix's ''[[Monthly Shōnen Gangan]]'' and eventually released in [[tankōbon]] format. The first tankōbon was released in Japan in October 2003.<ref>{{cite book| script-title=ja:キングダムハーツ (1) (コミック)|isbn=4757716575 | language = ja|author1=シロ・天野 |year=2003 |publisher=エンターブレイン }}</ref> The manga was released in the US by [[Tokyopop]] two years later in October 2005.<ref>{{cite book| title = Kingdom Hearts, Vol. 1 (Paperback)| date = October 2005| publisher = Tokyopop| isbn = 1598162179| url-access = registration| url = https://archive.org/details/kingdomheartsvol00shir}}</ref> Yen Press now holds the rights to publish the books for the USA market. The first series, ''Kingdom Hearts'', consists of four volumes, while the second series, ''Kingdom Hearts: Chain of Memories'', has two volumes. The third series, ''Kingdom Hearts II'', has ten volumes total, taking a hiatus to publish a fourth series based on ''Kingdom Hearts 358/2 Days'' which has five volumes total, after which Kingdom Hearts II resumed. As of April 2019, a fifth series based on ''Kingdom Hearts III'' has been serialised monthly in Gangan Online with Amano returning to do story and artwork.<ref>{{cite web |url= https://www.khinsider.com/news/Kingdom-Hearts-3-manga-to-begin-serialization-on-April-29th-15172| title = Kingdom Hearts 3 Manga to begin serialization on April 29th| date= April 25, 2019}}</ref> Yen Press also licensed the series and published it online in English on apps such as Comixology and [[BookWalker]] alongside the Japanese release. This series will soon have two volumes published in tankōbon format.<ref>{{cite book| title = Kingdom Hearts III, Vol. 1| isbn = 978-4757565913| author1 = 天野シロ| year = 2020| publisher = スクウェア・エニックス}}</ref><ref>{{cite book| title = Kingdom Hearts III, Vol. 2| isbn = 978-4757568433| author1 = 天野シロ| author2 = 野村哲也| date = June 2021| publisher = スクウェア・エニックス}}</ref>

The games have also been adapted as a [[light novel]] series, written by Tomoco Kanemaki and illustrated by Shiro Amano. Like the manga series, it is divided into separate series based on the games. ''Kingdom Hearts'' is divided into two volumes; "The First Door"<ref>{{cite book| title = Kingdom Hearts: The First Door – #1 (Kingdom Hearts) (Paperback)| isbn=978-1423103950| last1=Kanemaki| first1=Tomoco| date=August 5, 2008| publisher=Disney Press}}</ref> and "Darkness Within".<ref>{{cite book| title = Kingdom Hearts: Darkness Within – #2 (Kingdom Hearts) (Paperback)|isbn=978-1423103967|last1=Kanemaki |first1=Tomoco |date=August 5, 2008 |publisher=Disney Press }}</ref> ''Kingdom Hearts: Chain of Memories'' is divided into two volumes.

=== Television series ===
A pilot for a television adaptation of the first ''Kingdom Hearts'' game was commissioned in 2003 for the [[Disney Channel]], but did not go forward as a series.<ref name=takedown>{{cite tweet|user=SethKearsley|number=1581025737926070272|title=As some of you have already seen. The #kingdomhearts animatic is taken down. I got the call from an old friend at Disney who was politely asked to politely ask me to take it down.}}</ref> In October 2022, the pilot's director, Seth Kearsley, uploaded the pilot animatic to his personal YouTube channel and shared more details on the production. The cast of the games reprised their roles for the pilot with the exception of [[Haley Joel Osment]], who was unavailable due to scheduling conflicts and was replaced with [[Bobby Edner]].<ref>{{cite web | last=Deschamps | first=Marc | title=Canceled Kingdom Hearts Animated Pilot Released After 19 Years | website=ComicBook.com | date=October 12, 2022 | url=https://comicbook.com/gaming/news/kingdom-hearts-canceled-animated-pilot-released-disney-animatic-seth-kearsley/ | access-date=November 26, 2024}}</ref> According to Kearsley, the pilot tested well with their test audiences, but the decision was made not to go further into production due to the franchise's expansion and the difficulty of maintaining consistency with the ongoing game series.<ref>{{cite web |last1=Ngan |first1=Liv |title=Director of canned Kingdom Hearts TV series shares pilot episode |url=https://www.eurogamer.net/director-of-canned-kingdom-hearts-tv-series-shares-pilot-episode |website=Eurogamer |date=October 12, 2022 |access-date=October 12, 2022}}</ref> The animatic was later taken down by Kearsley at Disney's request, though it was later reposted by minor channels.<ref name=takedown/>

=== Potential film adaptation ===
On May 27, 2020, it was reported that a TV series based on the franchise was in development for [[Disney+]].<ref>{{cite web |title=Kingdom Hearts TV Show Reportedly Coming To Disney+ |url=https://www.ign.com/articles/kingdom-hearts-tv-show-disney-report |website=www.ign.com |date=May 27, 2020 |publisher=IGN |access-date=May 28, 2020 |archive-date=June 9, 2020 |archive-url=https://web.archive.org/web/20200609081800/https://www.ign.com/articles/kingdom-hearts-tv-show-disney-report |url-status=live }}</ref> On April 24, 2024, ''The DisInsider'' reported that an animated ''Kingdom Hearts'' film was in the works. While previously having been a show for Disney+, it was changed to a theatrical film. It was also noted that these are just rumours and nothing had officially been given the [[greenlight]].<ref>{{Cite web |last=Shuler |first=Skyler |date=2024-04-24 |title=The DisInsider Mailbag |url=https://thedisinsider.com/2024/04/24/the-disinsider-mailbag/ |access-date=2024-04-24 |website=Daily Disney News |language=en-us}}</ref>

=== Fandom ===
In October 2007, a fan-made [[web series]] of CG action films called ''Dead Fantasy'' was created by late web-based animator and writer, [[Monty Oum]]. ''Dead Fantasy'' featured ''Kingdom Hearts'' characters teaming up with ''[[Final Fantasy]]'' characters and competing against ''[[Dead or Alive (franchise)|Dead or Alive]]'' and ''[[Ninja Gaiden]]'' characters in [[Battle royal|battle royale-style]] brawls.<ref>{{Cite web|last=Kietzmann|first=Ludwig|date=October 3, 2007|title=Haloid creator mashes up Final Fantasy and Dead or Alive {{!}} Joystiq|url=http://www.joystiq.com/2007/10/13/haloid-creator-mashes-up-final-fantasy-and-dead-or-alive/|url-status=dead|archive-url=https://web.archive.org/web/20140912080441/http://www.joystiq.com/2007/10/13/haloid-creator-mashes-up-final-fantasy-and-dead-or-alive/|archive-date=September 12, 2014|access-date=December 23, 2020|website=Joystiq}}</ref><ref>{{cite web|url=http://gamingdead.com/2009/07/07/gd-at-ax-interview-with-monty-oum|title=GD at AX: Interview with Monty Oum|publisher=Gaming Dead|first=Meredith|last=Sweet|date=2009-07-07|access-date=2011-07-05|archive-url=https://web.archive.org/web/20150202221728/http://gamingdead.com/2009/07/07/gd-at-ax-interview-with-monty-oum|archive-date=2015-02-02|url-status=dead}}</ref><ref>{{cite web|url=https://www.nag.co.za/2015/02/02/monty-oum-creator-of-rwby-dead-fantasy-has-died/|title=Monty Oum, creator of RWBY, Dead Fantasy, has died|publisher=NAG|first=Rick|last=de Klerk|date=2015-02-02|access-date=2023-02-14}}</ref>
