KO is a status in Final Fantasy X. The victim is knocked unconscious and thus cannot act. This status occurs when a character's HP is reduced to 0 from taking damage or from being struck by an instant KO ability. If everyone in the party is KO'd (or petrified or ejected), it will trigger a Game Over unless at least one party member successfully escaped from the battle beforehand.

If the character who was to throw a blitzball to Tidus during Blitz Ace as per the affection mechanics is KO'd, someone else will throw it or the ball comes out of nowhere.

Protection

Support ability	Death Ward, Deathproof

Some enemies status attacks ignore immunities, however, where Death Ward and Deathproof will have no effect. Being in Zombie status can protect against instant death, as seen in the battle against Yunalesca.

The player can also negate the effect of KO when it happens with Auto-Life or Auto-Phoenix. Instant death from Doom counter expiring cannot be protected against.

Healing

Mix	Final Elixir, Final Phoenix, Mega Phoenix
Item	Mega Phoenix, Phoenix Down
