{{About|the series||Kingdom Hearts (disambiguation)}}

{{nihongo|'''''Kingdom Hearts'''''|キングダムハーツ|Kingudamu Hātsu}}, officially stylized as '''''KINGDOM HEARTS''''', is an {{w|Role-playing video game|role-playing game}} series developed and published by {{w|Square Enix}}, formerly {{w|Square (video game company)|Square}}. It is a collaboration between Square Enix and {{w|Disney Interactive Studios}} under the direction of {{w|Tetsuya Nomura}}. ''Kingdom Hearts'' is  a crossover between Square Enix and Disney properties based in a fictional universe.

The series consists of numerous entries across different video game platforms, with almost every game being re-released in a set of compilations on the PlayStation 3 and later the PlayStation 4, Nintendo Switch, and on PC. Many games have received enhanced ports with the subtitle "Final Mix", while others have gotten full-scale remakes. Although the bulk of the series can be played in these modern compilations, a few games are adapted into cutscene movies instead, and others remain exclusive to mobile devices. There are currently 13 main installments (bolded in the "Games" section below, although note that the [[Kingdom Hearts χ Back Cover|ninth]] is a movie).

There have been several types of merchandise released along with the games, including soundtracks, figurines, companion books, and a [[Kingdom Hearts Trading Card Game|trading card game]]. In addition, the games have been adapted into a {{c|Kingdom Hearts series|manga|manga series}} and {{c|Kingdom Hearts|novels|novels}}.

Most of the games in the series have been both critically acclaimed and commercially successful, though each installment has seen varying levels of success. As of March 2022, the ''Kingdom Hearts'' series has shipped over 36 million copies worldwide.<ref>[https://www.hd.square-enix.com/eng/ir/library/pdf/ar_2022en.pdf Square Enix 2022 Annual Report]: "The series is celebrating its 20th anniversary this year and has shipped over 36 million units worldwide."</ref>

''Kingdom Hearts'' features a mixture of familiar Disney and Square Enix characters as well as original characters designed and created by Tetsuya Nomura.

Typically, the games are structured into a set of worlds, being analogous to different levels. The gameplay in each world primarily centers around defeating enemies and completing linear objectives. In some games, travel between each level is automatic; in others, going to a new world is done through a [[mini-game]], such as the [[Gummi Ship]] or [[Dive Mode]]. Mini-games like these are an important part of the gameplay in the ''Kingdom Hearts'' series; nearly every installment features a wide array of mini-games, with many being required for story  progression.

There are many allies that aid the playable characters. Typically, the allies rely fully on A.I. controls, with later entries allowing for limited customization of their behavior. In addition to accruing [[party member]]s, allies can be called into battle through the [[Summon]] system. Alternatively, the player can temporarily expand the main playable character's array of abilities through use of [[Drive Form]]s, [[Dimension Link]]s, or the [[Link System]].

Another recurring element of the ''Kingdom Hearts'' series is the [[Report]]. It records information about the characters, story, and enemies, as well as providing simple hints, tracking progress through mini-games and side quests, and recording various other gameplay statistics.

Overall, the ''Kingdom Hearts'' series is designed as a single-player experience, although ancillary multiplayer modes or features are included in ''Kingdom Hearts Chain of Memories'', ''Kingdom Hearts 358/2 Days'', ''Kingdom Hearts Birth by Sleep'', ''Kingdom Hearts Re:coded'', ''Kingdom Hearts 3D: Dream Drop Distance'', ''Kingdom Hearts Union χ'', and ''Kingdom Hearts Melody of Memory''.

*The field theme for [[Beast's Castle]], debuting in ''Kingdom Hearts II'', is named "[[Waltz of the Damned]]" (although the title itself would not be visible in a game until ''Kingdom Hearts Melody of Memory'').

With a brief reprieve, the Union Leaders wonder if everything Darkness said is true meanwhile the fight against the entity left Ventus unconscious again with Lauriam apologizing to him for his actions. Then, he was alerted with news that his sister is alive by Elrena as her Chirithy saw her walking with someone in a [[black coat]]. Shocked at first but remembering they are in data Daybreak Town and the Pride Shift the Union Leaders knew that all their data existed here meaning someone could've accessed Strelitzia's. Hopeful that Strelitzia could be alive and worried about the state of the world. The group head to basement and found the world was being destroyed. Seeing the Ark room's condition and there were five pods left but with many trapped, little time and trying to keep hope alive the Union Leaders separate. Brain heads to the real world with Lauriam, Elrena and Ventus while Ephemer, Skuld and Player watch over the dandelions. Before leaving, he passed on his [[Master's Defender]] Keyblade and the Book of Prophecies to Ephemer.  

Overtime the Player's heart merges with that of a cloaked figure.

In their elderly years, the cloaked figure spirited a descendent of Ephemer named [[Xehanort]] to the [[Destiny Islands]] to protect him from the Darknesses, believing him to be the "Child of Destiny". As a child, Xehanort was told stories about his lineage and his destiny as the "Child of Destiny" who would one day leave the islands when he was strong enough. Due to his strong connection growing up he sampled through dreams his caretaker's memories of the Keyblade War, seeing people and worlds he didn't know but wanted to meet. As Xehanort grew, the cloaked figure faded into the afterlife, knowing they repaid their debt to Ephemer and the world was in good hands.

 

Xehanort's dreams continued, and he began to view the islands as small and uneventful, wanting to explore the worlds beyond. One day, he was visited by [[Ansem, Seeker of Darkness]], his Heartless from the future, who offered him a way off the island and Xehanort accepted. Getting his first taste of darkness his heart being affected by powerful negative emotions despite being horrified he was fascinated aware that his heart could still feel. He also believed that with a strong enough heart darkness could be channeled and controlled.

Then, one day Xehanort and his classmates were informed by Master Odin that the upperclassmen of Keyblade wielders were missing, including Baldr's sister, Hoder. In an effort to find them they split up into two groups to search the worlds with him, Eraqus and another apprentice, heading to Agrabah once there he realized that the world was still rebuilding from the destruction of the Keyblade War, as no humans were here. Then moved onto Wonderland, where they avoided the insanity of the Queen of Hearts, but Xehanort wondered if slaying those controlled by darkness was needed to protect the world. As they continued to travel the worlds the way they were to be protected differed among some of their upper classmates especially Vadir whose grief made him seek Kingdom Hearts to purge the Darkness but didn't follow through. But just like Union Leaders they were deceived by a Willful Darkness that sowed the seeds of sadness and pain first killing Hoder, then using him as a vessel strike down everyone else by the end Xehanort and Eraqus were all that survived or so they thought as Bragi was taken as Luxu's next vessel.  

Sometime later Xehanort opened the door in Ansem's basement, despite making [[Gummi Ship]] travel possible, Ansem worried about the world's stability. Soon he met King Mickey Mouse and they became great friends, conversing over many subjects, and finding solace in their companionship. Then, seeing Xehanort had continued the experiments in secret, accidentally creating the emblem Heartless Ansem forbade an further experimentation with the Heartless as they threatened the world's stability even more. Then, he accepted new apprentices [[Isa]] and [[Lea]] more devastating Ansem discovered the Ansem Reports, penned under his name, but written by Xehanort. He began to see that the damage he caused had become irreversible. To stop his interference, Ansem was sent to the [[Dark Realm]] by his apprentices allowing Radiant Garden to fall into darkness continuing on Xehanort sent a young Kairi into the other worlds in attempt to find a keyblade wielder believing she was a [[Princess of Heart]]. Some time after, Xehanort began to reclaim his memories and his ability to use the Keyblade. Then, turning the blade on himself and apprentices he created their heartless and most of the Nobodies to form the original [[Organization XIII]]. With his body temporarily gone his desire to forge the x blade and claim Kingdom Hearts lived on his Heartless, Ansem, Seeker of Darkness, and his Nobody, Xemnas.
