Accessories are equippable items introduced in Kingdom Hearts. When equipped to a character, they provide a number of functions to them, including a stat boost, protection against certain kinds of damage, and other additional effects.
In Kingdom Hearts II, Armors were introduced, granting defensive abilities, including protection against specific kinds of magic. Accessories became solely focused on improving the character's offensive stats and abilities.
 Kingdom Hearts
Accessories were originally the only kind of equipment the characters were granted other than weapons. They covered a wide range of abilities, and were able to improve the the character's defense, Hit Points, magic points, AP, and strength, as well as providing defense against one or more of the kinds of elemental magic, Fire, Blizzard, Thunder, and Dark. Accessories could also provide bonuses to magic and Summons.
As they were the sole kind of equipment in the game, they could be gained in any number of ways. Each world had at least one accessory that could be won during events or upon completion of that world. Some were found in chests throughout the game, especially in the End of the World. The most basic kinds could be purchased, most notably at the accessory shop in Traverse Town run by Cid. More complicated and powerful varieties of accessories had to be synthesized with the Moogles. Finally, on rare occasions, accessories were dropped by Heartless in the course of battle.
Three accessories underwent slight stat changes in Kingdom Hearts Final Mix, and fifteen new ones were added.
 Kingdom Hearts II
With the introduction of armors, accessories took on a simpler task in Kingdom Hearts II. Accessories only provided bonuses to a character's strength, magic, and AP. In addition, two accessories, the Lucky Ring and the Draw Ring, provided special abilities to the party when equipped on a character.
The weakest accessories can be purchased during the first visit to each world in game in the shops of Twilight Town, the Land of Dragons, Timeless River, and Halloween Town. In addition, many are uncovered through chests in various worlds. However, during the second section of the game, stronger accessories can only be obtained through synthesis. Unlike the first game, Heartless will never drop accessories.
It is interesting to note that the first potential accessory to be obtained in Kingdom Hearts II is dependent on game play and events. If Roxas fails to win the Struggle tournament, he will obtain a Medal accessory instead of the Champion Belt armor.
Sora, Donald, and Goofy each begin the game with one accessory slot. Through gameplay, more can be unlocked:
Other world-specific characters, such as Jack Skellington, Auron, and Beast have at least one accessory slot, but cannot gain any more through the course of the game. Likewise, Roxas only has one accessory slot and cannot obtain more.
 Kingdom Hearts 358/2 Days
In Kingdom Hearts 358/2 Days, ring panels are accessories that can be bought from the Organization Moogle. You can only equip one ring panel at a time and they can give various positive and negative status effects.
