Blitz Ace

Blitz Ace (エース・オブ・ザ・ブリッヅ) 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.

Final Fantasy X
Tidus can use Blitz Ace after he successfully executes eighty Overdrives. Whoever throws the ball is determined by Affection Mechanics.

Final Fantasy X-2
In the International version of the game, Tidus can be fought in the Coliseum and will use Blitz Ace against the party. When Tidus is recruited into the team, the game's A.I. will randomly choose Blitz Ace to be perfomed by Tidus.

The final boss, Shuyin, uses a similar move called "Terror of Zanarkand."

Dissidia Final Fantasy
Blitz Ace appears as an EX Burst for Tidus in Dissidia Final Fantasy. Tidus attacks the opponent with several sword thrusts before throwing a Blitzball at the opponent. The ball rebounds towards Tidus, and the player must stop a moving cursor as close to the center of Tidus's Overdrive meter as they can (similar to Final Fantasy X, but faster). The closer they are to the center the more Brave damage Tidus does as he kicks the Blitzball back at the opponent, consuming them in an explosion of light.

Dissidia 012 Final Fantasy
Blitz Ace reappears in Dissidia 012, once again serving as Tidus's EX Burst with unchanged effects.

Theatrhythm Final Fantasy
Blitz Ace is Tidus's exclusive skill, learned at Level 40. During BMS, whenever a boss-type enemy enters Omnislash activates automatically to inflict damage based on Tidus's Strength and Agility.
