Kingdom Key









The Kingdom Key (キングダムチェーン) is the most recognizable Keyblade in the Kingdom Hearts series, as it appears within each game of the series, and frequently serves as the default Keychain for cutscenes. In Kingdom Hearts: Chain of Memories, it is the only Keychain that Sora can visibly use, while in Kingdom Hearts 358/2 Days, it is the only Keychain of Xion's to appear in Story Mode, and excluding the final Mission, the only Keychain of Roxas's to appear in any cutscene. Furthermore, while Kingdom Hearts II normally depicts the equipped Keyblade within cutscenes, the Kingdom Key appears by default in the cutscene leading up to the Battle of 1000 Heartless, and within the Album pictures of Jiminy's Journal. In Kingdom Hearts 358/2 Days, it can be upgraded to the Kingdom Key+ and the Kingdom Key++.

The Kingdom Key draws out the true power of Sora's Keyblade, even though it is not the strongest Keychain. As such, it is the true form of his Keyblade, which means that it is also the default form of Roxas's and Xion's Keyblades. The Kingdom Key is not wielded by Sora exclusively; Riku, Roxas, and Xion have also used it, and King Mickey is often seen wielding the Kingdom Key D, a color-inverted version of the weapon.

For Roxas and Xion, the Keyblade they wield is in fact Sora's Keyblade, existing in multiple places at once. Roxas also obtains a second Kingdom Key after absorbing Xion; however, this is in fact Ventus's Keyblade, not Xion's.

The Kingdom Key D, a color-inverted Kingdom Key which King Mickey wields, is the Keyblade from the Realm of Darkness, which he obtained to mirror Sora's Keyblade from the Realm of Light.

Kingdom Hearts
When the Heartless attack Destiny Islands, this Keyblade, which Terra had promised Riku years ago, appears. However, because Riku sided with Darkness and was swallowed by it, this weapon "went down the list" and choose Sora to weild it instead; because the heart of Ventus resided deep within him, Sora was able to weild the Kingdom Key without any trouble.

Riku, being the original intended weilder, is able to hold it breifly when he reunites with Sora in Traverse Town; he returned it to Sora.

When Sora arrives in Hollow Bastion to rescue Kairi and the other Princesses of Heart, Riku explains the Keyblade was supposed to be his, taking it from him and giving him a Wooden Sword in its place. However, once Sora confronts Riku once more, the strength of his heart shows the Kingdom Key that he is the more worthy candidate.

Kingdom Hearts: Chain of Memories
When Zexion disguises himself as Sora, he wields a fake Kingdom Key Keyblade.

Kingdom Hearts 358/2 Days
When Roxas first uses Synch Blade, he summons two Kingdom Keys, then transforms them into the Oathkeeper and Oblivion.

Kingdom Hearts II
When Roxas is attacked by a lone Dusk outside the Old Mansion, he attempts to use his Struggle Bat to ward it off, but it fails to touch the monster. At that moment, however, the Kingdom Key replaces the Struggle Bat in a haze of data, and Roxas is able to defeat the Dusk. The Kingdom Key continues to materialize whenever Roxas needs to fight off Nobodies, until he is attacked by Axel within the Old Mansion's Basement. There, Roxas instead summons the Oathkeeper and Oblivion, but after defeating Axel and proceeding to the chamber in which Sora slumbers, he uses the Kingdom Key one final time in an attempt to strike down DiZ.

Kingdom Hearts coded
Data-Sora gains a data-version of the Kingdom Key in his Dive to the Heart. It is destroyed by Maleficent at Agrabah, but he gains a new Keyblade at Hollow Bastion. According to King Mickey, this Keyblade is closely connected to the power of the Heart.

Design
The Kingdom Key is depicted as a classic skeleton key approximately 3.5' long, with a long silver Keychain extending from the hilt, and a Hidden Mickey token on the end of the Keychain. The blade and teeth of the Keyblade are silver, the rainguard is blue, and the guard is bright gold. The teeth of the Keyblade form the outline of a crown which matches the crown charm Sora wears.

Gameplay
Gameplay with the Kingdom Key varies, as its combo is normally influenced by the amount of Combo Boosts and other Combo influencing abilities the player has equipped. The weapon's base combo in nearly every game is a basic three hit attack: A downward swing, a forward thrust, and a spinning slash, while its aerial combo is a downward, then upward slash, finished with a mid-air spinning slash.

In Kingdom Hears 358/2 Days, Roxas, Xion, and Sora have the opportunity to wield this weapon: Roxas and Xion, with no gears or the Zero gear equipped, and Sora, with any gear save for the Zero and Pandora gears.

Roxas and Xion have identical combos with both no gears and Zero gear. Their combo without any gears is the basic three hit combo, while his Zero gear combo is slightly different. It begins with a downward slash, followed by an upward swing with the capability of knocking the enemy in the air. From here, a -Combo is prompted, in which Roxas or Xion will perform a jump accompanied by a downward slash if executed. With another hit of the button, Roxas or Xion's -Combo concludes with a sliding swing of the Keyblade. If continued normally, combo concludes with a basic spinning slash. The aerial combo for Roxas's Zero Gear is noticeably shorter, with only two hits. It begins with a basic downward slash and finishes with a spinning slash.

Sora's combos with the Kingdom Key, meanwhile, never change no matter what gear is equipped. It will always be the same, default, three-hit combo: a sideways swing, a forward thrust, and a spinning slash. No -Combo opportunities are ever prompted. His swing speed, however, is noticeably faster than Roxas's.

Other appearances
The Kingdom Key also appears in the secret videos Another Side, Another Story... and The Gathering; in the former, Roxas briefly dual wields it along with Oathkeeper after tossing his Oblivion to a falling Riku in The World That Never Was, while in the latter, Terra pulls it from the ground at Keyblade Graveyard.

Most Kingdom Hearts merchandise features the Kingdom Key as Sora's weapon, including the Volume One and Volume Three Sora figures that appear in the Formation Arts Figures. Along with being the Keyblade packaged with "normal" Sora in the Series 1 Play Arts Figures, it is also seen with Roxas' figure and the rare Sora Limit Form figure.

The Kingdom Key is often used as a sort of cursor, as well as a symbol for attack abilities. The logo sequence for the Keyblade Graveyard also depicts the Kingdom Key being thrust into the background, summoning the text.

On the Japanese version of the Kingdom Hearts 3D: Dream Drop Distance website, the Kingdom Key act as a cursor for Sora's version of the website.
