Hide

Hide is a recurring ability usually associated with the Bard class. When a character uses this ability, he or she will be removed from battle and will not be able to fight or be damaged until the Show command is used. This command exists usually due to the Bard's low HP count compared to other jobs. The Hide status is usually associated with the command or similar abilities.

Final Fantasy IV
Edward can use this ability. He uses it automatically whenever he enters HP Critical status. The Hide status is applied while Edward is using the ability. The game's GBA ports include a bug, in which Edward can be both hiding and afflicted with Berserk allowing him to be near invincible until everyone else in the party is knocked out, which removes Edward's Hide status.

In the DS version of the game it can be obtained as an Augment by giving Edward at least two Augments before he leaves the party. This allows other characters to use it.

Final Fantasy IV: The After Years
Edward can use the ability Escape which functions similarly to Hide. He does not, however, automatically use it when he is in critical status. Escape has a Charge Time of 0.

Final Fantasy V
This is a Level 1 ability for the Bard class, learned for 25 ABP. When the command is issued, the status is given, and if all characters are in the status, then they all run from the battle unless it is impossible to do so. This status can also give rise to a couple bugs, primarily the Hidden Zombies Bug.

Final Fantasy IX
Hide is not an ability usable by the party, but is an enemy ability used by the Cactuar enemy as a counter to taking damage when above ground.

Final Fantasy XI
Unlike in other games, this ability is only available to the Thief class. It will instantly give the character the status effect Invisible for a random duration. If the thief is being pursued by a creature that tracks by sight, all enmity is lost. This ability can be used once every five minutes starting at level 45.

Final Fantasy Tactics A2: Grimoire of the Rift
Hide is an exclusive ability of the Bard class, which makes the user get the Invisible status. Hurdy also knows Critical: Vanish, likely as a reference to Edward's ability to automatically Hide when at Critical HP.

Final Fantasy: The 4 Heroes of Light
Hide is an ability learned by the White Mages that makes them unable to be targeted by enemies for their next turn. It takes two AP to use and is the third ability learned on the crown.

Final Fantasy Trading Card Game
Hide is the ability of one of Edward's cards. For the discard cost of another Edward card, Hide prevents Edward from being targeted by summons or effects until the end of the turn.
