Lightning is a warrior of Materia in Dissidia Final Fantasy NT. She is an Assassin-type character who represents Final Fantasy XIII, using a sword as her main weapon. Lightning returns from her previous appearance in Dissidia 012 Final Fantasy, in which she had a slightly similar combat style.
Lightning's default player name is Nameless Flash. Her manikin counterpart is Evanescent Glimmer, and resembles her Equilibrium attire.
Lightning's default costume is her "Guardian Corps Uniform", her outfit from Final Fantasy XIII. Its first alternate coloration recolors her outfit to resemble her Equilibrium attire from Lightning Returns: Final Fantasy XIII. The second alternate coloration recolors the outfit to resemble her "Guardian Corps Uniform" from Dissidia 012 Final Fantasy.
Her first alternate costume is "Knight of Etro", her main attire from Final Fantasy XIII-2. Lightning wears a silver and gold armor with a large feathered sash. The Goddess's Grace shield is part of her costume, but is not used for gameplay as she functions identically to her normal playstyle. The first alternate coloration recolors her armor gold and her feathered sash a gradient of white to yellow. The second alternate coloration recolors her armor bronze and her feathered sash pink.
Her second costume is "Equilibrium", Lightning's main garb in Lightning Returns: Final Fantasy XIII, and also her main attire in the story of Dissidia Final Fantasy NT. The "Night Lotus" shield is featured on her garb in the opening and ending FMVs, but is absent in-game.
Her third alternate outfit is "Midnight Mauve", a garb obtained during the main scenario of Lightning Returns in Yusnaan. The first alternate coloration is blue. The second alternate coloration is white.
Lightning is warmer and more nurturing than in Dissidia 012, due to retaining her memories. She acts as a motherly figure towards Vaan and Squall, and helps initiate first-timer Noctis in the circumstances behind the war. She criticizes the gods who have once again summoned them against their will, namely Materia, with her main concern being to return to her world rather than blindly fight Spiritus's forces. Nevertheless, she has a certain fondness of the world of the gods, so much so that her memories of it inhabit a doppelgänger that continues to fight to protect it.
Lightning primarily equips swords, and all of her weapons can be used by her throughout the Lightning Saga. Unlike previous appearances, none of her weapons transform into a gun, due to Lightning's new playstyle and the addition of alternate weapons.
Her default weapon is the Blazefire Saber from Final Fantasy XIII.. Lightning's first alternate weapon is Omega Weapon, her ultimate weapon from Final Fantasy XIII, previously wielded by her in EX Mode in Dissidia 012. Her second alternate weapon is Overture, Lightning's main weapon as a servant of Etro. Her third alternate weapon is Femme Fatale, a rapier she can wield in Lightning Returns: Final Fantasy XIII. Her fourth alternate weapon is Crimson Blitz, a blade restored from its previously damaged encounter by Lumina which acts as Lightning's main weapon in the story of this game. Her fifth alternate weapon is Excalibur, also from Lightning Returns which was a downloadable weapon that was part of the Ultimate Savior garb set.
Materia summons Lightning back to World B. She rescues Noctis from a manikin version of herself, before briefing him on his newfound predicament. They are greeted by the Warrior of Light, and together decide to visit Materia's domain. Materia informs the reunited champions that they have been summoned to fight one another to provide the realm with energy that will maintain its existence. Lightning resents Materia for summoning her against her will, and after being introduced to Spiritus and his chosen warriors, decides to head off with Terra, Squall, and Zidane.
The four decide to find out more about this new realm, and following Terra's advice seek out the help of Eidolons. After picking up the trail of one of them, Terra picks up on a second Eidolon close by. After Squall decides to press forward alone, Lightning volunteers to accompany him. They end up in an illusion of Eden where they find Snow wandering, asking how they are supposed to get home. She tells him that they can only fight. Snow thinks she is going to fight him, but Lightning refuses. Snow summons Odin and Lightning and Squall fight the Eidolon. After bringing Odin down, Lightning tells Snow that they are going to find a way to get everyone home, even him. Snow departs and Lightning thanks Squall for helping her, but he shrugs it off.
Lighting and Squall reunite with Terra and Zidane, and are joined by the Onion Knight, Vaan, and Y'shtola. Lightning informs them of their findings, and in turn learns about the planesgorgers draining the world of energy. As Lightning berates Vaan for not taking the situation seriously, the group decides to return to Materia and report their findings.
Lightning and the rest of Materia's champions engage in a final clash against Spiritus's forces to coax Shinryu out of hiding, the dragon god culpable for the planesgorgers. Lightning clashes with Garland, before dueling with Sephiroth alongside Noctis. Once Shinryu emerges, Lightning assists in bringing the malevolent force down once and for all. With the threat eliminated, Lightning and the others return home after bestowing her essence to Materia in the form of a crystal.
- Type: Assassin - Lightning can shift paradigms, thus changing her Bravery attacks. The Commando paradigm is used for up close enemies, and Ravager from a distance.
Lightning is a quick-hitting fighter with a focus on changing her Bravery moveset between close-range physical attacks and long-range magic spells. Unlike in Dissidia 012, she has no Medic paradigm and is focused on offensive attacks. She can change paradigms with , and can change at any time except while taking damage. Lightning can thus quickly change between movesets to combo them together and deal heavy damage with continuous attacks. While she has high combo potential, her spells in Ravager mode have low priority and less range than Marksmen-type characters, and she lacks vertical attack options. Her HP attacks have quick execution and are close to long range, but aside from Lightning Strike, are easy to dodge.

- Her victory line "Hmpf." "That's how it's done" is also used in Final Fantasy XIII.
- One of her opening lines is "You're flying awfully close to the sun." This alludes to when Lightning advised Sazh to fly towards Phoenix to get PSICOM off of their backs.
- Another of her opening lines is "We can win if we stay focused." This refers to fighting Long Gui in Final Fantasy XIII with Lightning as the party leader.
- Lightning resenting Materia summoning her in the new conflict refers to her similar sentiment towards Cosmos when she was summoned in the old conflict. Both refer to her distrust of the gods in the Lightning Saga.
- Lightning's playstyle refers to Lightning Returns: Final Fantasy XIII where she doesn't use gunblades and also thus uses the Blazefire Saber and the Overture Gunblades in sword mode.
- Lightning briefly teams up with Noctis during the staged battle late in the game while fighting Sephiroth, indirectly referencing how the latter's home game was originally meant to be part of Lightning's home series as Final Fantasy Versus XIII.
- Lightning was one of the first six characters announced for the Dissidia arcade game
