Blitz Ace (エース・オブ・ザ・ブリッツ, Ēsu Obu za Burittsu?, lit. Ace of the Blitz) is Tidus's strongest Overdrive from the Swordplay command debuting in Final Fantasy X. It starts with eight consecutive slashes to a single target, somewhat similar to Cloud Strife's Omnislash and Squall Leonhart's Lion Heart, and finishes with Tidus kicking a blitzball, which explodes on contact with the opponent.
Tidus can use Blitz Ace after he executes 80 Overdrives. Whoever throws the ball is determined by affection mechanics.
In the International version and HD Remaster of the game, Tidus can be fought in the Fiend Arena and will use Blitz Ace against the party. When Tidus is recruited into the team, the game's A.I. will randomly choose him to perform Blitz Ace.
Though not a true appearance of the ability, there is an allusion to it. Blitz Ace is an auto-ability exclusive to Guardian's Protector shield. When defending for a certain amount of time, Lightning is buffed with Bravery and Faith.
Blitz Ace is Tidus' EX Burst. Tidus starts the attack with its usual sword combo, but since he is alone, instead of someone throwing the blitzball to him, he hurls it in a manner that it rebounds off the opponent and into the air towards him as it becomes enveloped in energy. As he starts an overhead kick, the player must stop a moving cursor as close to the center of Tidus's Overdrive meter as they can. The closer they are to the center, the more Bravery damage Tidus does as he launches the blitzball at the opponent with the bicycle kick shot, consuming them in an explosion of light that deals HP damage.
Blitz Ace returns serving as Tidus's EX Burst with unchanged effects.
The Blitz Ace can be used by Tidus as part of a Crystal Drive attack.
Tidus's Dissidia art card can use Blitz Ace for a cost of two Water CP and discarding another Tidus card. Blitz Ace grants Tidus Brave until the end of the turn, and the turn Blitz Ace is used he can attack an amount of times equal to the damage the player has received.
Blitz is a German word for "lightning". In English it is associated with quickness.
Ace" is one of the values in trumps, the Japanese term for traditional Western playing cards. It means "one" in Old French and was borrowed from earlier dicing games, where it referred to the corresponding value on a six-sided die."
