Gestalt Drive (ゲシュタルトドライブ, Geshutaruto Doraibu?) is a recurring ability in the series. It is a Limit Break used by Lightning, originating from Dissidia 012 Final Fantasy. While the ability's animation varies, its finisher is Zantetsuken's Final Fantasy XIII animation, as "Gestalt Drive" combines Final Fantasy XIII Odin's Gestalt Mode abilities with Lightning's signature move Army of One, called "Scene Drive" in Japanese.
Gestalt Drive is Lightning's EX Burst where she attacks with a backlip and a barrage of gunfire before finishing with the Zantetsuken. The player has to enter the commands shown on the screen as Lightning attacks the opponent with Lightning Strike, Thunderfall, Stormblade, and Razor Gale, with the commands appearing at random. Lightning finishes the EX Burst with Odin's Zantetsuken, where she spins around with swords outstrecthed to unleash multiple blows that slit away the screen. She lands and the opponent is slashed again behind her, dealing HP damage from the spinning blows. Failing to input the commands skips to Zantetsuken and the attack deals less Bravery damage.
Gestalt Drive serves as LightnIng's Finishing Burst, obtained from the one-handed sword Durandal (XIII). After executing six attacks of the player's choice, Lightning finishes by slashing a targeted enemy repeatedly with the blades of the Zantetsuken, dealing HP damage twice. The combined finisher can deal no more than ~300000 damage to the target.
Gestalt Drive is Lightning's Champion summon ability. It inflicts neutral physical damage to one enemy, ignoring defense. It also grants Strength+ to all allies. Its animation is a mix of Army of One's Final Fantasy XIII and Lightning Returns: Final Fantasy XIII animations with Zantetsuken serving as its finisher. It is unlocked after complete chapter 13 and costs 2★ gauges to use. When used, "Blinded By Light" from Final Fantasy XIII play.
Gestalt is a German word for "form" or "shape". It is used in English to refer to a concept of "wholeness", in which the whole is greater than the sum of its parts.
