Kingdom Hearts (Darth Multiverse's Version)

Kingdom Hearts is a series of action role-playing games created by Japanese game designers Tetsuya Nomura and Shinji Hashimoto, being developed and published by Square Enix (originally by Square). It is a collaboration between Square Enix and The Walt Disney Company and is under the leadership of Nomura, a longtime Square Enix employee.

Kingdom Hearts is a crossover of various Disney properties based in an original fictional universe. The series centers on the main character, Sora, and his journey and experiences with various Disney characters, as well as some from Square Enix properties, such as Final Fantasy, The World Ends With You, and Einhänder, in addition to original characters and locations created specifically for the series.

The series consists of thirteen games available for multiple platforms and future games are planned. Most of the games in the series have been positively received anGamesd commercially successful. As of March 2022, the Kingdom Hearts series has shipped more than 36 million copies worldwide. A wide variety of related merchandise has been released along with the games, including soundtracks, figurines, companion books, light novels, a collectible card game, and a manga series.

Disney and Square Enix characters
Kingdom Hearts features a mixture of familiar Disney and Square Enix characters, as well as several new characters designed and created by Nomura. In addition to original locations, the Kingdom Hearts series features many worlds from Disney films. Sora must visit these worlds and interact with various Disney characters to protect them from enemies. Often, his actions in these worlds closely follow the storylines of their respective Disney films. The main characters try not to interfere with the affairs of other worlds, as it could negatively affect the universe's order. Various Final Fantasy characters also make appearances within several worlds throughout the series. This includes Moogles, small creatures who are another common element in the games. They provide the player with a synthesis shop in order to create and purchase items used in the game. The main cast from The World Ends with You also makes an appearance in the series in Dream Drop Distance, and Kingdom Hearts III features characters from Pixar films such as the Toy Story series and Monsters, Inc., as well as Schwarzgeist, one of the bosses from Einhänder. Nevertheless, the usage of Disney characters is not without restrictions. For example, Nomura had requested the use of Oswald the Lucky Rabbit in Kingdom Hearts III, but the response from Disney was that the character would be "too difficult" to use, with no further clarification or details from Disney.

Gameplay
The Kingdom Hearts games contain elements of action role-playing video games with 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 side quests available that provide bonus benefits to the characters. In most games, the player primarily controls the principal protagonist of the series, Sora. Sora is usually accompanied by Donald Duck and Goofy, who are artificial intelligence-controlled 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.

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 rail shooter. Because it received negative criticism in the first game, it was modified in the third game. 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 Queen Minnie as the royal chronicler. In 358/2 Days, Birth by Sleep, and Dream Drop Distance, the main characters write their own journal entries. The games are influenced by their parent franchise, Final Fantasy, and carry its gameplay elements over into their own action-based, 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 abilities. The amount of experience is shared with all party members and each character grows stronger as experience is gained.

Other media
Both Square Enix and Disney have released a wide variety of Kingdom Hearts merchandise including toys, figurines, clothing, and jewelry. Two of the games, Kingdom Hearts and Kingdom Hearts II, had a soundtrack released to coincide with the video games. These were followed by a nine CD complete set which featured both soundtracks and unreleased tracks. Kingdom Hearts has been adapted as a trading card game by the Tomy corporation of Japan. An English version of the game was released in November 2007 by Fantasy Flight Games. The video games have also been adapted into manga and novel series.

Like the Final Fantasy games, a series of "Ultimania" books were released in Japan for many of the games. These books include game walkthroughs, interviews, and extra information from the developers. Kingdom Hearts -Another Report- was released along with Kingdom Hearts II Final Mix+ and features game information, visuals by Shiro Amano, and a director interview. In North America, Brady Games released strategy guides for each game. For Kingdom Hearts II, they released two versions, a standard version and a limited edition version. The limited edition was available in four different covers and included a copy of Jiminy's Journal along with 400 stickers.

Sora has made guest appearances in other video games, including World of Final Fantasy and Super Smash Bros. Ultimate.

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. The manga was released in the US by Tokyopop two years later in October 2005. 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. 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.

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" and "Darkness Within". Kingdom Hearts: Chain of Memories is divided into two volumes. Kingdom Hearts II is divided into four volumes; "Roxas—Seven Days", "The Destruction of Hollow Bastion", "Tears of Nobody", and "Anthem—Meet Again/Axel Last Stand".

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. 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. 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. The animatic was later taken down by Kearsley at Disney's request.

On May 27, 2020, it was reported that a TV series based on the franchise was in development for Disney+.
