When Sora’s house is struck by lightning during a violent storm, his entire world comes crashing down around him, and he becomes separated from his two closest friends. The Storm disperses the three individuals to different realms. Concurrently, upheaval can be heard coming from inside the Disney Castle. King Mickey has gone missing, and Donald, the Court Wizard, and Goofy, Captain of the Guard, are on the hunt for him. During their travels, they come across Sora, who is also looking for his friends who went missing. It is explained to the three that the Heartless, terrifying monsters that lack hearts and originate from a dimension that no one knows about are the ones to blame for the destructive Storm.
Enticed by the strength of darkness, the Disney villains convince it to assist them in gathering the princesses of heart who are required to open a mysterious final door. This is accomplished by manipulating darkness itself. As soon as Sora, Donald, and Goofy found a connection between the Heartless, the Storm, and the disappearance of King Mickey, they banded together to aid other well-known Disney characters in their fight against the Heartless and save their worlds.
Players of Kingdom Hearts assume the role of Sora, the keyblade wielder, and put themselves in his very enormous shoes. Sora can launch attacks with the blade, and as he levels up, he will unlock other episodes that can be linked together automatically. Both learning magic and putting healing things into a quick menu, which can only be used in real-time, are abilities that Sora possesses. Donald and Goofy will accompany Sora on his journey, in addition to a third character unique to each world or Disney film. Their artificial intelligence and equipment can be customized but cannot be controlled directly. Many items, including raw materials for synthesis, will drop from defeated enemies. Sora can repurpose these by bringing them to the Synthesis shop in Twilight Town. They can be transformed into valuable items, accessories, and weapons there.
Flying through space in a Gummi Ship requires Sora and his friends to get from one world to the next. It is possible to personalize the Gummi Ship, from its speed and armor to its armaments and design, by piecing together components salvaged from damaged Gummi Ships, discovered in worlds, or purchased from a shop. As the player continues through the game, they can construct more extensive and complicated ships. Plans for these ships can be obtained from defeated foes or NPC that can automatically build a Gummi Ship according to the player’s specified preferences.
