Block

Block (リフレクトガード), also known as Guard (ガード), is a skill introduced in . It allows the user to block many frontal attacks with their weapon.

Mechanics
In Kingdom Hearts, Guard is an combat ability that costs 2 to equip. It is a single blocking swing triggered by pressing while standing stationary or walking. Blocking any enemy attacks will count as having the Keyblade deflected, which may prompt the usage of Counterattack if Sora is suffering from normal recoil.

In Kingdom Hearts Chain of Memories, Guard is an enemy card effect that costs 40 CP to equip and lasts for one reload. It blocks all frontal attacks, nullifying damage.

In Kingdom Hearts II, Guard is an action ability that costs 2 AP to equip. It is triggered by pressing while standing stationary or walking. Roxas's version of Guard only blocks attacks from the front, while Sora's version can also block some attacks from the rear during activation due to the initial spin. Guard provides invulnerability to damage for applicable attacks during a successful animation.

In Kingdom Hearts II Final Mix, Limit Form has Guard as one of its default abilities. Limit Form's version activates quicker, lasts longer, and has a shorter recovery period than the standard version, though lacks the ability to defend from the rear during activation.

In Kingdom Hearts 358/2 Days, Block is an ability panel. It is triggered by pressing while standing stationary, and holding the button extends the duration of the block whenever any attacks come into contact in succession. It can be upgraded from Block LV1 up to Block LV2, Block LV3, and Block LV4 by linking Block LV+ Ⓛ (ガードアップⓁ) panels to it. Increasing the ability's level increases blocking speed and decreases the recoil that occurs after a successful block. It can also be linked to various sub-panels, which can be synthesized at the Moogle Shop.

In Kingdom Hearts Birth by Sleep, Block is a that has a maximum level of 3. It is triggered by pressing while standing stationary or walking, and holding the button extends the duration of the block.

In Kingdom Hearts Re:coded, Block is a Bonus Booster ability that is triggered by pressing while standing stationary. Holding the button extends the duration of the block whenever any attacks come into contact in succession.

In Kingdom Hearts 3D: Dream Drop Distance, Block is a that is triggered by pressing  while standing stationary or walking. Holding the button extends the duration of the block.

In Kingdom Hearts III, Block is an that costs 2  to equip. It is triggered by pressing while standing stationary or walking. Unlike in previous games, Block can be used while airborne and while underwater. Block has an area of effect of 220° in front of Sora, and a duration of 0.6 seconds. After a successful Block, Sora will continue blocking any attacks that connect until his guard is lowered; each subsequent connection will reset the guard stance. Some enemy attacks can break Sora's guard, which staggers him and immediately renders him vulnerable to damage unless the Risk Dodge ability is equipped and is activated.

In Kingdom Hearts Melody of Memory, characters will automatically use Block against enemy attacks during boss battles. Depending on the player's performance, it may fail to activate, causing the player to take damage.
