Lightis

Lightis is the het ship between Lightning Farron and Noctis Lucis Caelum from the Final Fantasy fandom.

Canon
As Lightning and Noctis are from different Final Fantasy series, they have never met in canon. Since Lightning is from Final Fantasy XIII, while Noctis's is Final Fantasy XV. Both of their Final Fantasy games are two of the well liked FF sages/trilogies, from how their stories continued after their first games. Lightning's FF series is made out of three games, while Noctis's has a few prequels, filled in gap stories and then a few alternate endings where some of them are featured in an film, anima and book than just a few other games.

While they have never met in canon, they do in the Dissidia series, where they both appear as warriors of Materia, as well as allies in Dissidia Final Fantasy NT. After Noctis awakens in the dimension world he encounters a black Manikin of Lightning that attacks him, until he is saved by the real Lightning. Because she looks exactly like the "woman" who tried to attack him he wasn't sure if he should trust her, while Lightning and a few of their allies could see that Noctis is new to this and is indeed one of the warriors in their side of the war they were called upon to fight in. The also appear in Dissidia Final Fantasy Opera Omnia.

Noctis and Lightning have a similar loathing for their future brother-in-laws, and confrontations would often rise to conflict. Yet they would both end up having a mutual respect for them. As Lightning traveled, fought along side and had even saved Snow's life a few times and that allowed her to give Snow and Serah her blessing to their marriage. Along with Noctis getting the Sword of the Father back from him after he learns that Ravus choose tp honour Luna's wishes and memory of her; and when Ravus became a daemon he used what remained of his humanity to beg Noctis to kill the monster he became. In one of the altered versions of FFXV, Dawn of the Future, Ravus's spirit watches Luna and Noctis being happily wedded, while the alternate ending of the DLC, Episode Ignis, has an older Ravus bequeaths the Sword of the Father to Noctis in person. In Lightning Returns: Final Fantasy XIII, Lightning had also faced a similar requested task when Snow asks her to destroy his Cie'th, but choice to help him, in order to save his soul, through their shared love for Serah. The two have also encountered and spoke with the spirits of their dead lover and sister, Lunafreya and Serah, before being reunited with them.

Similarities and Comparison
