Overview
Further information: Characters of Kingdom Hearts

Kingdom Hearts features a mixture of familiar Disney and Final Fantasy characters, as well as several new characters designed and created by Nomura. Though the series features locations unique to the Kingdom Hearts franchise, worlds from Disney films are heavily explored. Sora must visit these worlds and interact with popular Disney characters to protect them from enemies. Often, Sora's actions in these worlds follow closely to the storylines featured in their accompanying Disney films. In dialog, Donald Duck tells Sora not to interfere with the worlds too much, since it would cause problems. Moogles, small creatures from Final Fantasy, are another common element in the games. They provide the player with a synthesis shop in order to create items for use in the game.

Gameplay
The Kingdom Hearts series contained elements both 3rd-person fighting and role-playing games elements. The games are driven by a linear progression to the next story event, usually told in the form of a cut scene, though there are numerous side quests available that provide bonus benefits to the characters. Furthermore, there are allies to aid the main character, Sora. The allies in play rely fully on A.I controls, though players could later modify and customize their abilities usage frequency. The combat system takes on real time, meaning Sora could engage the enemy directly, various actions, such as attack, magic, are executable, during the battle or after the battle.

In Kingdom Hearts: Chain of Memories, the combat system was altered slightly, Sora is no longer aided with his friends, all of his combat commands, are only executable via Cards. The real time combat system was also taken away, where the scene flashes whenever Sora engages an enemy, taking them to a wider combat field.

Gummi Ships are another common theme in the series, where it serves as a transportation for Sora and co. to travel towards other worlds, players can modify, customize via blueprints and selected parts. In the release of Final Mix, the the first game contained Gummi Ship missions side quest. However, due to the criticisms regarding the Gummi Ship customization was too complex, the third game's Gummi Ship was toned down, providing easier and wider modifications, allowing players to customize it into either a small classed battle ship, or a grand carrier.

Another recurring element of Kingdom Hearts series is Jiminy's Journal, which functions as a bestiary and provides hints and simple character informations. The journal also records Sora's mini-games' results, and unfinished sidequest, allowing players to have easier resolutions to track the game.

In Kingdom Hearts II, the battle system introduced a new gameplay element: Form Drives, which allows Sora to gain access to new abilities via his combat garment, and wielding two Keyblades in for a limited time. (However, only several forms have this ability). Magics are simpler to execute, and Sora's MP gauge will recharge automatically one it is used up. Another gameplay element introduced in the third series of the franchise is the Reaction Command, various combat abilities only executable via several situations.

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 culminate 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.

Story
The three main games in Kingdom Hearts series focus on the adventures of Sora and his search for his friends, Kairi and Riku. The first game shows how Sora is separated from his friends when their world is invaded by an army of corrupted hearts known as the Heartless. During the invasion, he obtains a special weapon known as a Keyblade. Soon after, Sora meets Donald Duck, the Disney Castle court magician, and Goofy, the Disney Castle captain of the royal guard. Donald and Goofy are searching for the "key" per instructions from King Mickey. The three band together and travel to different Disney themed worlds, sealing the hearts of the worlds to prevent more Heartless invasions. Along the way they encounter a group of Disney villains, led by Maleficent, that are controlling the Heartless. The three eventually discover that a man named Ansem is the true antagonist. Ansem's plan is to open the door to Kingdom Hearts. Sora, Donald, and Goofy defeat Ansem, and seal the door with the help of Riku and King Mickey on the other side of the door.

After sealing the door to Kingdom Hearts, the three begin searching for Riku and King Mickey. They encounter a mysterious fortress called Castle Oblivion. Upon entering the fortress, they begin to lose their memories. The three encounter a group of dark hooded villains referred to as the Organization. After defeating the Organization members in the castle, Sora learns his memories have been manipulated by a girl named Naminé who is controlled by the Organization. To allow them to regain their memories, Naminé puts Sora, Donald, and Goofy to sleep for a year. While the three are ascending to the top floor of the castle, Riku and King Mickey arrive in the basement and began traveling to the top as well. Riku fights the darkness in his heart and learns to accept his dual nature between light and dark.

A year later, Sora, Donald, and Goofy awaken and continue their search for Riku and King Mickey. They learn of the Nobodies and their leaders, Organization XIII. Afterwards, Maleficent is resurrected and joins with Pete, another Disney villain, to continue her quest for power. Sora once again travels to many Disney-themed worlds and resolves the troubles caused by Organization XIII, the Heartless, Maleficent and Pete, and local villains. Meanwhile, Kairi is kidnapped by the Organization. They meet King Mickey, who reveals the true nature of Ansem, the antagonist of Kingdom Hearts. The Ansem who Sora defeated was actually the Heartless of Xehanort, a student of Ansem the Wise. Xemnas, the leader of Organization XIII, reveals himself to be the Nobody of Xehanort. The three arrive at the headquarters of Organization XIII, with Kingdom Hearts looming overhead. Ansem the Wise uses a device that dissipates some of Kingdom Hearts' power, but a system overload causes the machine to explode and kill Ansem. At the top of Organization XIII's castle, Sora and his friends battle Xemnas, who uses the remnants of Kingdom Hearts to fight them. After Xemnas' death, Sora and Riku are reunited with their friends at Destiny Islands, their home.

Time Line


The series is mostly in sequential order.The first game in the timeline is Birth by Sleep, telling the story of three keybearers during the Keyblade War. 10 years later is where the first Kingdom Hearts picks up, revolving the first adventure of Sora. Next is Chain of Memories, taking place in between Kingdom Hearts 1 and 2. It also takes place during parts of 358/2 Days. Kingdom Hearts 2 follows Chain of Memories, and takes place one year after Kingdom Hearts 1 though it is more so a sequel to Kingdom Hearts 1 rather than the Gameboy Advance game. Finally is Coded, which takes place right where Kingdom Hearts 2 left off.

358/2 Days doesn't have a real spot in the time line, for it takes place from when Sora turned into a Heartless, to right before the beginning of Kingdom Hearts 2, which is 358 days. The 7 days of Kingdom Hearts 2's prequel can be an extension to the DS game. So from when Sora sacrifices himself to when he wakes up is a little more than a year, if you still count the time between the events of Hollow Bastion and the ending of Kingdom Hearts 1. 358 is also a sequel to Chain of Memories, since the GBA game mentioned "the other side of Sora's heart," and it takes place right after Riku's story, telling what happened from when Riku joined DiZ to his disappearance and search for Roxas.
