Kingdom Hearts is the basis and main setting of the Square Enix's video game franchise of the same name. A powerful light force, with immense and mysterious abilities, able to cast away the "everlasting darkness". Kingdom Hearts' power is sought by many malevolent figures like Maleficent, or Master Xehanort, who want to harness it's power, either for their own benefit, or to restore the balance between the light and darkness. The primary element and location of the series, apparations of Kingdom Hearts, including the location from the World that Never Was, or from the Door to Darkness, or from the Keyblade Graveyard, also appear in the villain tournaments, particularly in the second Disney Villains War, sought by the villain forces, for their own purposes. As a location, it also appears as one of the main battle sceneries of the second Disney Villains War.
