but they share the same sky—
one sky, one destiny."

Kingdom Hearts is a series of fantasy Action JRPG games, co-produced by Squaresoft (now Square Enix) and Disney, directed by Final Fantasy character designer Tetsuya Nomura, and starring characters from both companies. It's basically the darkness-lightingly popular Final Fantasy series meets Disney (along with some other Square Enix properties later on). The series is well-known for its incredibly bizarre premise and increasingly complicated plot, not to mention its increasingly absurd sequel subtitles.
Sora is a young boy living a peaceful but boring life on an island with his best friends Riku and Kairi. This is until the day his world is engulfed by The Heartless, an eldritch species that feed on the hearts of innocent people and literally consume entire worlds. Sora is sucked through a portal and winds up in Traverse Town, a crossroads world that has become the refuge of those who have lost their worlds to the Heartless. As he begins to search for his missing friends, Sora is granted the mysterious Keyblade: the only thing capable of closing the gaps that the Heartless are using to invade the worlds.
With the aid of Donald Duck and Goofy, two royal knights searching for their missing king, Sora must travel to all of the different worlds and use the Keyblade to lock them safely away from the Heartless and those who plot to use the Heartless to further their own ends. Meanwhile Riku, having ended up in another world, becomes obsessed with rescuing Kairi at all costs and is tempted by the same power of darkness that Sora is trying to seal, setting up the two best friends for a fateful confrontation.
As Sora and Riku grapple with their newfound powers and responsibilities, an ever-expanding mythology begins to unfold around the legendary Kingdom Hearts: the source of all hearts and the goal of many an antagonist.
The first three games, released from 2002-2005, tell a trilogy in which Sora discovers his ability to wield the Keyblade and searches for his missing friends, battling the forces of darkness and exploring the Disney worlds along the way. It would not be until the third game, Kingdom Hearts II, that it was made clear the source of the evils plaguing the worlds was Xehanort, a dark Keyblade Master who was eventually established as the Big Bad of the Dark Seeker Saga.
The next three games, released between 2008 and 2010, would see the series branch out into handheld consoles as it primarily focused on other characters besides Sora who could wield the Keyblade, and eventually had Sora learn of his connection to these new characters. The origins of Xehanort would also be detailed in this handheld trilogy.
The final set of games in the Dark Seeker Saga, released between 2012 and 2019, gradually returned to consoles as it saw Sora, Riku, and their friends learn of the true scope of Xehanort's ambitions for Kingdom Hearts, and thus the heroes prepared for a climactic final battle foretold in ancient times as they mustered any hero of light they could against Xehanort and his XIII Seekers of Darkness. This final set of games also gave players a deep dive into the ancient lore of the Kingdom Hearts universe as it planted seeds for the future of the series.

Kingdom Hearts as a whole provides examples of:
- 11th-Hour Superpower:
- The Final Form transformation in Kingdom Hearts II. Granted, it's available for a while before the final boss, but it's hard to unlock quickly. It's really, really broken too, seeing as how it automatically attacks with every movement, including flying or drinking potions.
- In Kingdom Hearts: Birth by Sleep, Aqua gets the game's best Keyblade in the Final Episode, the semi-hidden true conclusion to the game's storyline. It also forces you to use it in the secret episode added in the final mix version.
- Plus, for the final battle of the prologue section of Kingdom Hearts II, Roxas gets to dual wield keyblades for the final showdown with Axel. It plays like Sora's drive version, except there isn't a gauge, so it's basically unlimited.
- Upon entering the final world in Kingdom Hearts: Chain of Memories, Sora is given an ability called "Trinity Limit" which gives you the ability to decimate any enemies on the screen provided you obtain one Goofy and Donald card during the battle.
- Kingdom Hearts: 358/2 Days: Roxas gains the ability to dual wield the Oathkeeper and Oblivion Keyblades during the first part of Day 358 (the last mission). His attacking speed and power increase dramatically, letting him quickly kill the Neoshadows that spawn with only one or two hits.
- 13 Is Unlucky:
- Organization XIII consists of thirteen members who like to walk around in Black Cloaks and do nasty things, which is ambiguously justifiable in that they lost their hearts and are trying to reclaim them. The means of trying to reclaim their hearts, however, involves the distortion of the heart of all worlds. Kingdom Hearts 3D [Dream Drop Distance] reveals that the Organization's true purpose is to serve as vessels to Xehanort, who seeks to reforge the χ-blade by pitting thirteen darknesses against seven lights (the Princesses of Heart). But with Sora foiling his goals, Xehanort is trying again with a second Organization.
- Sora is described in the Grid as Combatant 13, Foreshadowing Xehanort's plan to use him as his thirteenth vessel.
- Castle Oblivion, which is used as a base by members of the aforementioned Organization, has thirteen floors.
You hold the mightiest weapon of all.
So don't forget:
You are the one who will open the door.
