Universe of Kingdom Hearts

The Kingdom Hearts video game series, developed by Square Enix in collaboration with Disney, takes place in an unnamed fictional universe with numerous self-contained worlds based on intellectual properties from both companies. Many of these worlds are based on animated Disney movies, though Kingdom Hearts II introduced worlds based on live-action Disney films as well. In addition to the Disney worlds, a number of original worlds appear over the course of the series. The series centers around the main character Sora's search for his friends and his encounters with Disney and Final Fantasy characters on their worlds. The first game, Kingdom Hearts, takes him through each world to lock their keyholes and prevent the Heartless from destroying them. The sequel Kingdom Hearts: Chain of Memories takes place in Castle Oblivion, where he visits memory-based simulations of many of these worlds that are generated on-the-fly as he travels through them. In Kingdom Hearts II, Sora helps the residents of these worlds again in search of his friend Riku. The Kingdom Hearts games have been both critically acclaimed and commercially successful and the design of the worlds has been praised for its faithfulness to the source material.

Concept and design

The Kingdom Hearts games are divided into various game levels, referred to as "worlds", which the player progresses through over the course of each game. Worlds vary in appearance, typically dependent on the Disney setting which they are based on. The worlds' graphics resemble the art style from the originating Disney film and the worlds are inhabited by characters from their respective films; for example, Hercules and Philoctetes appear in Olympus Coliseum from Hercules, while Aladdin, Princess Jasmine, and the Genie appear in Agrabah from Aladdin.^[1] The game worlds consist of interconnected field maps where battles and plot-related events occur. Players travel from one world to another via a Gummi Ship, or in Kingdom Hearts Birth By Sleep, characters travel via "keyblade glider".^[2] Worlds created specifically for the game mirror the overall appearance of the other worlds and predominantly feature characters from Final Fantasy games and original characters.

Though Disney gave director Tetsuya Nomura freedom to choose which characters and worlds would be used in the games, he and his staff tried to stay within the established roles of characters and boundaries of the worlds.^[3] Nomura found managing and keeping consistent multiple worlds to be problematic.^[4] After determining the number of worlds in the universe, Nomura picked ones he felt would fit into the series' scenario. The list was then evaluated by his team and finally by Disney representatives.^[5] Nomura tried to maintain the same number of worlds in each game and made an effort to minimize any overlap in the overall look and feel of each world. He and his staff accomplished this by categorizing various Disney worlds by appearance and setting.^[6] For example, a world based on The Jungle Book was considered for the first game, but was omitted due to its similarity to Deep Jungle from Tarzan.^[5][7] They also tried to take into account worlds with Disney characters that would be interesting.^[8] For example, Nomura chose to include a Mulan world for its unique atmosphere.^[9] The Tron world's design was meant to emulate an old computer game. Nomura got the idea to include this world after seeing a Disney employee making a Tron game. He hoped that the fact that it was so different from the other worlds would make it enjoyable to players.^[10]

Common elements

Nomura intended hearts as well as the strengths and connections of the heart to be a common theme in the games.^[7] Characters within the Kingdom Hearts series are composed of three parts: body, soul, and heart. The body acts as a vessel for the heart and soul, with the soul giving life to the body.^[11] The heart holds their memories, and gives them emotion, light, and darkness. When darkness consumes a character's heart, they become corrupted and turn into Heartless; a Nobody is created from the remaining body and soul. Heartless act as forces of darkness, seeking to consume more hearts, including those of worlds.^[12] In addition, it still appears that people can "die" like normal if not transformed into a Heartless. Disney's Hades rules over the afterlife (or, more accurately, the underworld), where the deceased of various worlds seem to end up, including Final Fantasy X's Auron.^[13]

The Kingdom Hearts universe is divided into planes of existence called "realms". Most of the series takes place in the "realm of light". Opposite the realm of light is the "realm of darkness", where Kingdom Hearts resides and where Heartless are born. The "in-between realm" is a plane where Nobodies come into existence.^[14] As well as these known realms, Ansem the Wise was banished to a "realm of nothingness", which he described as a realm "where all existence has been disintegrated".^[15][16]

Heartless and Nobodies

The Heartless (ハートレス, Hātoresu^?) are actually hearts corrupted by darkness, lacking a body or soul. They are named "Heartless" for their total lack of emotional capacity and are the most common type of enemy the player encounters in the Kingdom Hearts games. Originally, there were only Pureblood Heartless, black shadow creatures that lacked hearts who were born of pure darkness that usually exist in the Realm of Darkness, and rarely appeared in Realm of Light (the universe of the series). But the experiments by Ansem the Wise and his apprentices into the capacity of the heart lead to the seemingly unintentional creation of Heartless in the Realm of Light.

While researching these Pureblood Heartless, Xehanort and Ansem's other apprentices devised the means to create the artificial Emblem Heartless via the corruption of living hearts.^[17] Unlike the Purebloods, which dissolve into black smoke when defeated, Emblem Heartless release hearts once defeated. However, unless the Keyblade was used to defeat the Heartless, the stolen hearts go off into the Realm of Darkness and the Heartless are recreated. Ordinarily, the Heartless are mindless and function on instinct, but they obey those with strong will.^[18] However, in worlds closer to darkness, the Heartless are stronger and become uncontrollable. They invade worlds through corridors of darkness, which are unpredictable pathways that interlink the many worlds.^[19]

When Heartless are created, the body and soul of those with strong hearts that have lost their hearts to darkness may become another type of creature called a Nobody (ノーバディ, Nōbadi^?).^[14] As they lack hearts to possess light or darkness, they are "nothing", yet still exist within the Kingdom Hearts universe.^[20] Unlike Heartless, Nobodies are able to attack with definite planning.^[21] Members of Organization XIII, a group of Nobodies central to the plot of the series, kept their human form because they possessed strong hearts and thus remember their original existence, while weaker Nobodies assumed malformed, inhuman forms.^[22] Most members of the Organization control one type of Nobody, suited to their fighting style.^[23]

Like the Emblem Heartless, Organization XIII and the Nobodies have an insignia, an upside-down, incomplete heart—which was designed to look like a splintered heart as a complement to the Heartless emblem.^[24] However, upon being defeated, a Nobody fades into a state of non-existence until its Heartless counterpart is destroyed with the captive heart released, recreating the original being they were splintered from.^[25]

Unversed

The Unversed (アンヴァース, Anvāsu^?) are creatures that appear in Kingdom Hearts Birth by Sleep, prior to the Heartless and Nobodies within the continuity. Being extensions of Vanitas that feed off the negative emotions of people, the Unversed were used by Master Xehanort as the foundation of his master plan to obtain the ultimate powers of darkness, the same plan that resulted with him assuming his Terra-Xehanort incarnation. In the end, the Unversed ceased to be after Vanitas integrated back into Ventus and was subsequently destroyed within Ven's subconscious. The Unversed are described by Nomura as being "those who were not well-versed in their own existences."^[26]

Dream Eaters

The Dream Eaters are to be the main enemies of Kingdom Hearts 3D: Dream Drop Distance. Like the Heartless, they are described by Nomura as being created by darkness, but a different kind of darkness inside "the world enclosed by sleep". According to Nomura, there are two known types: those who eat dreams and create nightmares, and those who eat nightmares. Further information regarding the Dream Eaters has yet to be revealed.^[27]

Keyblades

The Keyblades (キーブレード, Kīburēdo^?) are key-shaped weapons created to combat darkness and are currently the only thing that can free hearts from a Heartless form.^[28][29] The Keyblades also have the ability to lock and unlock all manner of doors and keyholes.^[30] A Keyblade changes in appearance with Key Chains that are unique to each world. Some worlds have more than one Key Chain, where as others may have none. Its main purpose is for combat. A driving element to the first game was the ability to seal the "heart" of a world, preventing it from being destroyed by Heartless. In Kingdom Hearts II, the player uses it to unlock pathways between worlds that were closed after the events of the first game.^[31] While Sora is the only one who mostly uses the Keyblade in the first game, the later games reveal more Keyblades used by many others. In Birth by Sleep, the Keyblades can be transformed into hovercrafts called Keyblade Gliders, which can be used to travel from world to world, making Keyblade wielders the only people with the means of transportation between worlds before Gummi Ships were used.^[32]

χ-blade

The χ-blade (χブレード, Kīburēdo^?), pronounced the same as "Keyblade", is a special Keyblade introduced in Birth by Sleep that is capable of directly unlocking Kingdom Hearts. It is a double-handed weapon that is basically two Keyblades that intersect in an X shape, with additional lines that give it the shape of an actual sword. The χ-blade exists alongside Kingdom Hearts, unlike regular Keyblades which exist to join Kingdom Hearts. The χ-blade is created when a heart of pure light and a heart of pure darkness intersected, both equal in power. With the creation of the χ-blade, the user can summon and open Kingdom Hearts.

In Birth by Sleep, Master Xehanort took Ventus under his wing to train him in order for him to become a Keyblade Master, and had him fight multiple Heartless by using his inner darkness. However, Ventus refused to use that darkness and was defeated as a result. Master Xehanort decided that because Ventus was too reluctant to use his darkness, he would extract that darkness from Ven's heart to create Vanitas. He would then send Ventus to be trained by his friend, fellow Keyblade Master Eraqus, to make Ventus stronger, since both he and Vanitas had to be of equal strength to create the χ-blade, and Ven was still too weak in comparison to Vanitas (when Vanitas was created, he took all of Ventus' experience, leaving him weak and inexperienced). Over time, Ventus manages to reach the same level of power as Vanitas, and is eventually forced to fuse with Vanitas, which creates the χ-blade. However, while Vanitas possesses Ven's body, completing the χ-blade in the physical realm, he is unable to take control of his heart, leaving their fusion incomplete within Ven's subconscious; this would allow Ventus to fight Vanitas from within his subconscious, while his friend Aqua and King Mickey are forced to fight their complete fusion in the physical realm. In the end, Ventus manages to destroy Vanitas within his mind, effectively allowing Aqua to destroy the χ-blade in the physical realm.

Kingdom Hearts

The titular "Kingdom Hearts" is the "heart of all worlds" and the source of hearts, being in the shape of heart-shaped moon. An object of immense power, it is a central plot element that drives the conflict within the series, appearing through the gathering of hearts, be they from worlds or people. In the game prequel, having a blue-tint, Xehanort nearly achieved obtaining the power of Kingdom Hearts when the Lingering Will stopped him. Though only touched on in the first game, appearing as a sphere of light beyond a white door which Xehanort's Heartless was intending to open, Kingdom Hearts' role is expanded as Organization XIII's goal to become whole again. To that end, during 358/2 Days, they used Roxas and Xion to defeat enough Emblem Heartless to form Kingdom Hearts over the World That Never Was, expanding it more until Xion's demise and Roxas's departure from the Organization. By Kingdom Hearts II, Kingdom Hearts was nearly complete until Ansem's sacrifice reduced the amount of hearts it was composed of as Xemnas uses its power to battle Sora's group when they refuse his request to gather more hearts.

Worlds

The World That Never Was is a new setting introduced in a secret trailer in Kingdom Hearts. The heart-shaped moon is known as "Kingdom Hearts", a central plot point throughout the series.

In the Kingdom Hearts universe, travel between worlds is not normally possible. Worlds are protected from extraterrestrial interference by an invisible shell.^[33][34] When the heart of a world is opened, the shell breaks apart, appearing as a meteor shower.^[33][35] Fragments from the wall are called "Gummi blocks" and can be used to make spaceships called "Gummi Ships", which serve as the main mode of travel between the various worlds. Gummi Ships can be shaped into any structure, and the origin of the Gummi Ship material allows for travel to other worlds.^[33][36] Gummi blocks can serve different functions, from navigation to offense and defense.^[1][37] Another method to travel between worlds are the "corridors of darkness"—interdimensional pathways which erode the user's heart with darkness.^[33] These pathways are normally used by Heartless and Nobodies,^[19] but have been used by other characters in the series, including Riku and Mickey Mouse.^[33]

Those who travel between worlds are advised to limit their interactions with the inhabitants of foreign worlds in order to maintain the world order.^[38][39] For this reason, the main characters change their appearance in certain worlds to avoid standing out. In the worlds based on The Little Mermaid and The Nightmare Before Christmas, Sora, Donald, and Goofy transform into undersea creatures and Halloween monsters, respectively.^[40][41] For The Lion King, they transformed into animals (or, in Donald and Goofy's case, less humanoid forms) because Nomura felt that it would appear odd to have Sora and the others interact in their standard forms, since no humans appear in that film.^[10]

Disney worlds

The majority of worlds that appear in the games are based on Disney films. Most of these worlds, such as Wonderland, the Land of Dragons, and Deep Jungle, follow abridged versions of the stories found in their respective films. Agrabah notably covers the first two Aladdin films in Kingdom Hearts and Kingdom Hearts II, while Halloween Town only mirrors its film in the second game, having an unrelated plot in the first game. On the other hand, worlds like Monstro and Neverland focus heavily on the main Kingdom Hearts plot, the latter being reduced to Captain Hook's ship, where Riku reveals to Sora that Kairi has lost her heart. Beauty and the Beast is an interesting case—the Beast appears in Kingdom Hearts to aid Sora when he temporarily loses the Keyblade. After Beast's Castle is restored at the end of that game, the Beast becomes a pawn in the plot of Organization XIII during Kingdom Hearts II (and Gaston is essentially replaced by Xaldin as the world's villain).

During the development of Kingdom Hearts II, Nomura had more creative freedom due to advances in technology. Port Royal and Pride Land, in particular, benefited from these advances. In Port Royal, the character models were generated from live-action pictures using a new program.^[9] Nomura had wanted to include a world based on The Lion King in the first game, but could not since its engine could not process quadrupedal character models properly, a feature which was resolved for Kingdom Hearts II.^[10] A sub-world of Disney Castle is Timeless River, meant to be the "past" of Disney Castle, shortly before it was built.^[42] The world is portrayed in black and white; Nomura had intended it to be this way from the beginning of development.^[10] The world has many throwback effects including intentionally poor sound quality to imitate old cartoons. In this grayscale world, Sora's character model is simplified to the style of early cartoons, while Goofy and Donald Duck revert to their original designs from when they first appeared in Disney cartoons.

In addition to the Gummi Ship minigame, minigames feature prominently in certain worlds. The 100 Acre Wood in all three games consists entirely in minigames based on classic Winnie the Pooh shorts, with Sora taking on the role of Christopher Robin. Olympus Coliseum features optional fighting tournaments; due to Hades' popularity, the Underworld was added in Kingdom Hearts II, where Hades has opened his own tournament.^[43] While Atlantica is a normal world in Kingdom Hearts, albeit with a special "underwater" control scheme, it becomes an interactive rhythm game in Kingdom Hearts II which is completely unrelated to the overall story and serves as mere filler.^[10] Finally, Space Paranoids features a Light Cycle mini-game that strongly deviates from the original film. Nomura included this minigame because he knew people associated the Light Cycles with Tron.^[10] Kingdom Hearts Birth by Sleep introduced several new Disney-based worlds to the series, such as Castle of Dreams, Enchanted Dominion, Dwarf Woodlands and Deep Space, and it has been confirmed that the upcoming Kingdom Hearts 3D: Dream Drop Distance will introduce more new worlds, such as La Cité des Cloches and Prankster's Paradise.

Original worlds

The worlds created specifically for the series predominantly feature original and Final Fantasy characters and figure more centrally to the overarching plot of the Kingdom Hearts series. The first world of each game serves as a tutorial to introduce new gameplay elements and frame the story. Destiny Islands, the home world of the main characters, Sora, Riku, and Kairi, serves this function at the beginning of the first game and Kingdom Hearts Re:Coded. The next available world serves as a hub world, where the player returns multiple times throughout the game to unfold the main story. Traverse Town, a world cobbled together from the remains of worlds destroyed by the Heartless, fills this role in Kingdom Hearts, but becomes the tutorial world in Kingdom Hearts: Chain of Memories. The penultimate world of each game wraps up many plot threads in preparation for the final world. Hollow Bastion is this world for Kingdom Hearts, but, in Kingdom Hearts II, it is the hub world.^[10][44] Twilight Town is both the tutorial world and the penultimate world in Kingdom Hearts II, containing a secret pathway to the final world of that game.^[45] The final world culminates in a battle with the main antagonist of the game. End of the World, made out of the worlds that lost their hearts to the Heartless,^[46] and the World That Never Was are the final worlds of Kingdom Hearts and Kingdom Hearts II, respectively. Kingdom Hearts: Birth by Sleep differs slightly, however. In its case, the Land of Departure serves as the tutorial world, hub world and where the plot threads wrap up. The final world in the game is the Keyblade Graveyard, where each of the main characters' final battles take place.

Hollow Bastion plays a central role in the backstory of the series, as the home world of a majority of the Final Fantasy characters who appear in Kingdom Hearts, as well as the original home of Ansem the Wise, the ruler of that world, then called the Radiant Garden,^[47] and Kairi, who was sent to the Destiny Islands as part of an experiment conducted by Ansem's apprentice, Xehanort.^[48] Ansem studied the darkness in people's hearts with six apprentices, including Xehanort. His apprentices continued this dangerous research without his permission, causing the world to become overrun by darkness. Deserted, the castle was later adopted by Maleficent as a headquarters. Castle Oblivion, another villainous hideout and the main setting of Kingdom Hearts: Chain of Memories, consists of multiple floors which transform into memory-based reconstructions of other worlds, via special cards. Finally, Organization XIII is based in the World That Never Was, a world in the in-between realm that houses Kingdom Hearts. This conception of Kingdom Hearts was designed to appear as the heart-shaped moon from the cover of the first Kingdom Hearts game. When the scenario writer, Kazushige Nojima, created the scenario, he described it as a moon floating in the World That Never Was. Upon reading that, Nomura thought of using the visuals from the first game to create a connection.^[7]

Reception

The series' setting has garnered a mixed to positive reception from critics. Following Kingdom Hearts's initial announcement, publications expressed skepticism towards the first game's viability.^[49][50][51] Andrew Reiner of Game Informer stated that despite the extreme differences between Final Fantasy and Disney properties, they blend well together along with the new content created for the series. A second Game Informer reviewer, Matt Miller, described the concept as a "hard sell", describing the combination of the two properties as "ridiculous". Though in contrast, he stated the franchise's formula is successful.^[52] The graphics of the games have received generous praise, with particular focus on their similarity to the source material. IGN stated that the "worlds look very much like their filmed counterparts".^[53] Japanese gaming site, Gpara.com also praised the look of the worlds.^[54] GameSpot referred to the worlds as "wonderfully rich familiar environments",^[55] and GamePro described the worlds as "spot-on with the original movies."^[56]

Following the release of the first game, the Disney settings were well received by critics. Allgame's Scott Marriott stated the Disney settings are the most attractive feature of the game and considered some of the world choices a surprise. He praised the level designs, commenting that a good amount of familiar elements from the Disney films were integrated into them. Marriott further stated that though the stages were small, interacting with beloved characters and exploring familiar settings were enjoyable aspects.^[57] Maura Sutton of Computer and Video Games attributed the Disney elements as a major factor in creating the game's "astounding worlds". She summarized her review by calling Kingdom Hearts a "delightful mixture of two enchanted worlds".^[58] Video game critics of Kingdom Hearts: Chain of Memories expressed disappointment at the limited number of new worlds to explore in the game.^[51][59] 1UP.com's Bryan Intihar lauded Kingdom Hearts II's environment, calling it appealing and stating it was an improvement over the first title's. He described the level designs as "impeccable", citing the presentation of Timeless River stage's atmosphere. Intihar further commented that the expansions and changes to previous worlds made them "feel fresh".^[60] In contrast, Reiner described the Disney elements in Kingdom Hearts II as "tacked on".^[52]
