Summons

A Summon is a special character that can be magically called on to aid Sora in the Kingdom Hearts series. They have been present in all released games so far, although the mechanics of using them differ from game to game. In the original Kingdom Hearts, most of the summons are obtained by finding special gems in various Worlds. The gems can then be given to the Fairy Godmother, staying at Merlin's House in Traverse Town; she uses her magic to restore their spirit and release their power, thus making the summon avaliable. All of these summons are victims of the Heartless' quest to destroy the Worlds. As explained by the Fairy Godmother, the summoning gems are the crystallized forms of strong, good-hearted denizens that did not fall victim to the darkness during the destruction of their worlds, and so are able to be called into battle for a limited time. Two summons, Genie and Tinker Bell, are allies from Worlds Sora has visited, and join him of their own free will upon locking the Keyhole of their world. They do not need to be released by the Fairy Godmother before they can be used. In Kingdom Hearts: Chain of Memories there are Summon Cards that Sora obtains during his ascend in Castle Oblivion. Some Magic Cards enable Sora to perform summons. These cards are created from Sora's memories, so the summons are the same ones from Kingdom Hearts, with the addition of Cloud. In Kingdom Hearts II, summons come from special charms found scattered throughout the worlds, which Sora can immediately use without having to unlock them. The charms from Kingdom Hearts II work differently than the summon gems from Kingdom Hearts. While most of the summon spells on the first game gave a temporary body to the soul contained within the gem, the charm actually teleports the summonable character directly from their world. The Summon menu in Kingdom Hearts is located within the Magic menu during battle. Each summon requires a specific amount of MP to be performed, and the summon lasts until its MP bar is fully consumed (or until the player dismissed it manually). In order to perform a summon the player needs to have two friends in the battle with and they both must be conscious. This means that Sora cannot perform summons during battles he is fighting alone, or when one or both of his allies are knocked unconscious. In Chain of Memories, once Sora plays that specific summon's card, the summoned character will appear, perform one or more attacks/actions (depending on the amount of cards stocked) and immediately disappear. The Summon menu was given its own area in the Command Menu in Kingdom Hearts II because of the inclusion of a second menu that could be accessed during battle. In addition, Kingdom Hearts II summons no longer require MP to be summoned; they now use the Drive Gauge to count down their time instead, and again the player must have two friends in battle in order to perform a summon.
