Item

Items (アイテム) are a recurring mechanic in the  series. They are used in battle, in item synthesis, and in story progression.

Battle items
Battle items (バトルアイテム) are consumable items that can be equipped to party members and used in the field. They typically restore a party member's HP or MP. In , Kingdom Hearts II, and Kingdom Hearts 358/2 Days, equipped battle items can be used by selecting the Items command in the Command Menu. In Kingdom Hearts II and 358/2 Days, equipped items can be set to shortcuts for easy access.

Item slots
In Kingdom Hearts and Kingdom Hearts II, only a certain amount of battle items can be taken into combat at once, as each party member is restricted to the amount of item slots that they have. Each character begins with a certain amount of item slots, while Sora, Donald, and Goofy gain more by achieving bonuses.

Item cards
In Kingdom Hearts: Chain of Memories, battle items take the form of item cards, as part of the card-based combat system. Instead of healing a character, item cards restore used attack and magic cards to their deck. Unlike most other card types, item cards cannot be reloaded once used.

Item commands
In Kingdom Hearts Birth by Sleep, Kingdom Hearts Re:coded, and Kingdom Hearts 3D: Dream Drop Distance, battle items take the form of item commands, as part of the Deck Command combat system. Unlike other command types, item commands can be used a limited number of times, and they are equipped in limited quantities to a slot in the Command Deck; however, they do not have a cooldown period after each use. Item commands may restore a character's HP or other gauges, heal status effects, or activate Command Styles.

Camp items
Camp items (キャンプアイテム) are consumable items that must be used in the menu.

Key items
Key items (キーアイテム) cannot be consumed or spent. They are typically used to trigger scripted events or advance the story.

Other items
The following may also appear in the Items menu, but they can be considered separate categories:
 * Weapons
 * Armor
 * Accessories
 * Summon Charms
