Kingdom Hearts (キングダムハーツ Kingudamu Hātsu?) is one of the major entities in the Kingdom Hearts universe. It is the heart of all worlds, and the source of ultimate power and wisdom. It can be considered an aggregate of hearts. Xehanort's Report III There are other entities in the series known as Kingdom Hearts, although they are artificial replicas of the true Kingdom Hearts.


The colors of each individual Kingdom Hearts correspond to its composition. For example, the Kingdom Hearts constructed by Organization XIII from the "hearts of men" is yellow, while the Kingdom Hearts revealed by Master Xehanort's use of the χ-blade is blue. In Kingdom Hearts III, the Kingdom Hearts, once again summoned by Xehanort, was a fiery gold, but whenever Xehanort corrupted it or drawn power from it, it becomes a conglomeration of dark and foreboding colors, including purple and dark blue. As it prepared to purge the universe, it was fiery orange.[1]


Early history[edit]

In the "age of fairy tales", the world was whole and full of light. People believed the light came from Kingdom Hearts, the heart of all worlds, which was protected by its counterpart, the χ-blade. Due to the secret manipulations of the Master of Masters, his students, the five Foretellers tasked with protecting the light, began to mistrust each other after receiving a prophecy of the coming war.[2][3] They began competing over the world's Lux, believing it would give them the power to push back the oncoming darkness, but in the end, their efforts collapsed into internecine conflict that embroiled the entire world.

After the Keyblade War, the events of the "age of fairy tales" became legend and it was eventually believed that the cause of the war was that many came to desire the power of light contained within Kingdom Hearts, and they clashed together, wielding the Keyblades they created in the image of the χ-blade. Their greed and jealousy introduced darkness into the world, and in the aftermath of this Keyblade War, darkness covered the world, the χ-blade was shattered into twenty pieces, seven of light and thirteen of darkness, and the "true" Kingdom Hearts disappeared into the darkness. However, the world was restored by the light within the hearts of children, but as many individual worlds separated from each other. Kingdom Hearts 3D: Dream Drop Distance

As a Keyblade wielder, Xehanort studied the legends surrounding Kingdom Hearts, the χ-blade, and the Keyblade War. After he became a Keyblade Master, he searched for a way to reforge the χ-blade, summon Kingdom Hearts, and restart the Keyblade War in order to purge the world from the darkness that plagued it. Kingdom Hearts III

To further his plans, he extracted the heart of his pupil, Ventus, to create Vanitas. He left Ventus with his fellow former student, Eraqus, with the intention of having him and Vanitas clash in the future to create the χ-blade.

Kingdom Hearts Birth by Sleep[edit]

"This χ-blade will open a door―one that leads to all worlds! Then, Keyblade-bearing warriors will flock here from each and every one of them, to battle for the light within Kingdom Hearts! And just like the legend says, the Keyblade War will begin!"
Kingdom Hearts as it appears in "Birth by sleep".

Master Xehanort draws Terra, Ventus, and Aqua to the Keyblade Graveyard, the site of the legendary Keyblade War. During the initial clash between Xehanort, the three friends, and Vanitas, Xehanort summons Kingdom Hearts in the sky overhead.

While Ventus and Vanitas clash, Xehanort faces Terra, who he encourages to embrace the darkness. When Ventus and Vanitas fuse, creating the χ-blade, Xehanort uses his power as a Keyblade Master to extract his own heart and implant it in Terra, with the intention of seeing the results of the new Keyblade War in his new body.

However, Ventus and Aqua's combined efforts succeed in defeating Vanitas and destroying the χ-blade, while the new Terra-Xehanort is defeated by Terra's Lingering Will and is knocked unconscious. As Terra-Xehanort is swept away by the explosion of light from the χ-blade, Kingdom Hearts is covered by clouds and disappears from the sky.

Between Kingdom Hearts Birth by Sleep and Kingdom Hearts[edit]

An amnesiac Terra-Xehanort is taken in by Ansem the Wise, and he becomes his top apprentice. Together with the other apprentices, he and Master Xehanort's co-conspirator, Braig, conduct experiments into the heart, which lead to the release of the Heartless into the Realm of Light. They overthrow and banish Ansem, with Xehanort taking Ansem's name and, soon after, the hearts of himself and his fellows, creating his Heartless, Ansem, Seeker of Darkness, and the first Organization XIII, with his Nobody Xemnas at its head. While Xemnas leads the Organization in creating a Kingdom Hearts formed from the hearts of people, with the secret plan of using it to transform the other members into vessels for Master Xehanort's heart, his Heartless manipulates Maleficent into creating and opening the door to a Kingdom Hearts formed from the hearts of worlds.

Kingdom Hearts[edit]

"Behold the endless abyss! Within it lies the heart of all worlds: Kingdom Hearts! Look as hard as you are able, you'll not find even the smallest glimmer of light. From those dark depths are all hearts born, even yours."
Ansem, Seeker of Darkness
The Door to Darkness which leads to Kingdom Hearts.

Ten years after the clash at the Keyblade Graveyard, Maleficent and her alliance of villains seek out a way to reach Kingdom Hearts, in the hopes of gaining immeasurable power and knowledge and dominion over all worlds.

To accomplish this, they search for the Seven Princesses of Heart, maidens that possess hearts of pure light who, when brought together, will reveal the Final Keyhole leading to Kingdom Hearts. Additionally, they release hordes of Heartless into many worlds so they will consume the worlds' hearts. They destroy many worlds, and the hearts gather in the Realm of Darkness to create Kingdom Hearts. Although they manage to capture all seven Princesses, each of the villains is defeated by Sora.

Ansem, now possessing Riku's body, creates a Keyblade of heart from the hearts of the Princesses. However, the Keyblade and Final Keyhole are incomplete, due to Kairi's heart residing in Sora's body. Sora appears to drive Ansem off, but after he uses Ansem's Keyblade to free Kairi's heart, Ansem reappears and uses the completed Keyhole to travel to the End of the World, while the others flee Hollow Bastion.

Sora, Donald, and Goofy return to Hollow Bastion, and Sora locks the Final Keyhole, stopping the great influx of darkness that was emerging from it. They then travel to the End of the World, formed from the remains of the worlds taken by the Heartless. Deep within, at the border between the Realm of Light and the Realm of Darkness, they find Ansem.

After a long battle, Ansem reaches the Door to Darkness, beyond which lies the Realm of Darkness and Kingdom Hearts. Ansem forces the door to open, expecting for Kingdom Hearts to fill him with the power of darkness. However, the light of Kingdom Hearts overwhelms him, destroying him. But even with his defeat, the darkness that surrounds Kingdom Hearts threatens to overwhelm the Realm of Light, along with an immeasurable horde of Heartless. To stop the Heartless threat, Sora closes the Door to Darkness with the help of Riku and King Mickey, who become trapped on the other side. The world hearts that were taken by the Heartless are freed, and the worlds are restored.

Kingdom Hearts 358/2 Days[edit]

Once Roxas is inducted into Organization XIII, their plan to collect hearts in order to create their own Kingdom Hearts begins in earnest. Zexion explains to Roxas that once Kingdom Hearts has acquired enough hearts, it will have the power to make everyone in the Organization whole again. However, unknown to the rest of the Organization, except for Xemnas and Xigbar, this plan is actually a ruse to ensure cooperation. Xemnas actually plans to use the power of this artificial Kingdom Hearts to turn the Organization into vessels for fragments of Master Xehanort's heart, as part of the plan to recreate the χ-blade.

After Roxas and Xion collect many hearts, Xemnas shows the other Organization members the Kingdom Hearts that has appeared over the Castle That Never Was and how close they are to finishing it. It grows to be five times its original size by the end of the year.

When Roxas defeats Xion, and she begins fading away, she asks him to make sure Xemnas does not achieve his goal of obtaining Kingdom Hearts, and to free the hearts they captured.

Kingdom Hearts II[edit]

"Hear me, Kingdom Hearts! It seems we must begin anew. Ah, but know this: I will give to you as many hearts as it takes. Mark my words. You can no more be complete without me than I without you. Heed me, Kingdom Hearts! Lend me your power, so that we may be complete! The power to erase the fools that hinder us!"

With Roxas and Xion gone and Sora awakened, Organization XIII begin manipulating Sora into collecting hearts for Kingdom Hearts. They release Heartless into many worlds, forcing Sora to fight and defeat them. Saïx eventually reveals this plan to Sora at the Battle of the 1000 Heartless, in order to throw Sora's heart into turmoil. Although Sora continues to fight the Heartless, he resolves to stop the Organization's plan.

Upon reaching The World That Never Was, Sora and company see Kingdom Hearts floating overhead. It can be seen from anywhere in the Dark City and in the Castle That Never Was.

Xemnas merging with his broken Kingdom Hearts as he promises to make it complete once again.

While they ascend the Castle That Never Was, Ansem the Wise attempts to encode Kingdom Hearts as data. However, the machine is unable to process the many hearts within, and it explodes, damaging Kingdom Hearts and sending Ansem to the Dark Margin. Countless hearts rain down from Kingdom Hearts over the Dark City, spawning Heartless. When Sora's group confronts Xemnas atop the Alter of Naught, Xemnas laments the broken Kingdom Hearts, stating he must start all over again. When Sora, Riku, and Mickey refuse his command to gather more hearts, he attacks Sora, but is defeated.

In order to gain more power, Xemnas merges with his Kingdom Hearts. A new door appears, resembling the Door to Darkness, allowing Sora and his companions to enter Kingdom Hearts and confront Xemnas. Even with the power of Kingdom Hearts, Xemnas is finally defeated. The ultimate fate of his Kingdom Hearts is unclear.

Kingdom Hearts 3D: Dream Drop Distance[edit]

The artificial Kingdom Hearts created by Xemnas appears in the sky above Riku's version of The World That Never Was.

Kingdom Hearts III[edit]

Xehanort is able to recreate the χ-blade and he summons Kingdom Hearts with it. However, before Kingdom Hearts's power can be unleashed, Eraqus convinces Xehanort to surrender. The hearts of Xehanort and Eraqus depart together to the afterlife, while Sora and his friends use the χ-blade to close Kingdom Hearts.

Notes and references[edit]

  1. ^ Director's Secret Report XIII, p. 26; Tetsuya Nomura: "I think of "all life has heart" as the most basic premise of KH. The heart of worlds was a great heart that gathered everything that formed those worlds: the natural things such as the trees in the forests, the oceans and rivers, the flowers and such. The heart of people, as it is called, was the collected hearts of the humans and animals and such that lived in those worlds. A Kingdom Hearts is considered to be an aggregation of the originally invisible "proofs of life" known as hearts." Translation via Goldpanner.

The Master of Masters had an eye that gazes into the future. He bestowed upon five of six apprentices a copy of the Book of Prophecies, in which was written the events to come."
