Final Fantasy XV
Noctis Lucis Caelum is the only son and heir of King Regis Lucis Caelum CXIII of Lucis; the Caelum dynasty safeguards the Crystal, a divine artifact connected to the world's deities. When he was five years old, Noctis was chosen by the Crystal as the "True King", a prophesied figure who would purge Eos of the Starscourge, a plague that will trigger eternal darkness on Eos and turns living things into monstrous Daemons. At eight years old, Noctis is attacked by a Daemon and is sent to the nation of Tenebrae for healing, where he meets and bonds with the nation's princess Lunafreya Nox Fleuret. However, Noctis and Regis are forced to flee Tenebrae when it is attacked by the Niflheim Empire. By the events of Final Fantasy XV, Lucis is under siege from Niflheim, and Regis agrees to a ceasefire. As part of the treaty, Noctis is to marry Lunafreya, and Regis dispatches him to Altissia where they are to be married. Following Noctis' departure, Niflheim attacks Lucis' capital Insomnia, steals the Crystal and kills Regis. Noctis—together with his three companions and sworn protectors Gladiolus Amicitia, Prompto Argentum and Ignis Scientia—sets out on a quest to retrieve the Crystal and defeat Niflheim.
To fulfill his role, Noctis collects the Royal Arms, weapons of the ancient Lucian monarchs, from tombs across Lucis. He also gains the aid of the Astrals, divine beings who granted the Crystal to the Lucian line—he is in turn aided by Lunafreya, her attendant Gentiana, and Niflheim's chancellor Ardyn Izunia. Ardyn is later revealed to be Ardyn Lucis Caelum, the immortal older brother of Noctis's ancestor Somnus who swore revenge on both the Crystal and Somnus's bloodline because they demonized him for taking the Starscourge into his body to heal the infected. Noctis gains the favor of the Astrals Titan and Ramuh, but when he finally reaches Altissia and Lunafreya awakens the Astral Leviathan, Niflheim attacks and Ardyn mortally wounds Lunafreya, disrupting the ritual. With her last strength, she helps Noctis subdue Leviathan before giving him the Ring of the Lucii, an artifact through which he can access the Crystal's magic. Noctis then heads for Niflheim's capital of Gralea, burdened by the loss of Lunafreya and tormented by Ardyn.
Arriving in Gralea to find its population turned into Daemons, Noctis finds and is pulled into the Crystal. Noctis learns from the Astral Bahamut of Providence, a power borne from the Crystal, the Royal Arms and the Ring of the Lucii capable of destroying the Starscourge forever, the price of wielding it being Noctis's own life. Waking up ten years later, Noctis reunites with his companions as they travel to Insomnia where they defeat the rogue Astral Ifrit and the enslaved Lucii before facing Ardyn. After defeating Ardyn in the physical world, Noctis sacrifices himself to fulfill his role as the True King by purging the Starscourge with the Lucii helping him completely destroy Ardyn's spirit. In the game's post-credit scenes, having confessed his feelings for his friends during a rest before the final battle, Noctis reunites with Lunafreya in the afterlife.
Noctis is one of the main characters in Brotherhood: Final Fantasy XV, an anime following his early journey and how his companions came to travel with him. In the opening and concluding episodes, Noctis learns of the fall of Lucis and faces the Daemon that nearly killed him in his youth. Initially helpless against it, he draws strength from his friends and the memories of his father to kill the Daemon. Noctis also made a brief appearance in the CGI movie Kingsglaive, as a young child in a wheelchair. Noctis would have been the central character of a future downloadable content (DLC) episode Episode Noctis: The Final Strike, the finale of a planned tetralogy of DLC episodes dubbed Dawn of the Future. Aside from the first planned instalment Episode Ardyn, all other episodes were cancelled. It was instead remade into the novel Final Fantasy XV -The Dawn of the Future-, depicting an alternate ending to the game where Bahamut decided to wipe all life from Eos as Ardyn amassed too much power during Noctis's slumber to be stopped. When Noctis learns this and that Lunafreya was resurrected by Bahamut to aid him in his scheme, he makes peace with Ardyn so they can save Eos. While Ardyn uses the Ring of the Lucii and sacrifices himself to destroy the Astral's soul, Noctis battles and kills Bahamut after saving Lunafreya. With Bahamut's death, the other Astrals ceased to be as the Crystal shatters after absorbing the Starscourge into itself. In the story's epilogue, Noctis and Lunafreya are wed in Altissia. A Play Arts Kai figurine of Kai has also been developed.
Outside Final Fantasy, Noctis also appears as a DLC character in Namco's fighting game Tekken 7 as a friend of Lars Alexandersson. Lars' voice actor, Junichi Suwabe, enjoyed the interactions between both Lars and Noctis. Tekken producer Katsuhiro Harada commented it was his idea to include Noctis within the game as he was surprised by Final Fantasy XV as well as the coincidence that game from the franchise was released closely with Tekken 7. Additionally, Harada wanted to surprise fans by grabbing an RPG character by adding it to a fighting game and thus had multiple interactions with Hajime Tabata in order to get the permission to feature him in Namco's game. In the making of the character, the developers wanted Noctis to emulate his techniques from Final Fantasy XV with their own hardware. He was created to be accessible to newcomers of the Tekken franchise. Nevertheless, they received a model to follow by Square Enix. However, one technique was based on Lars' Lightning Screw which resulted into their relationship in the DLC trailer. Besides Noctis' regular costume, he wears one hooded entirely created by the Namco staff. The others were created by Square Enix. Noctis was featured in a collaboration with Puzzle & Dragons. He appears in Itadaki Street: Dragon Quest and Final Fantasy 30th Anniversary, and also appears as a playable character in the mobile RPG, Final Fantasy Brave Exvius, and the crossover fighting game Dissidia Final Fantasy NT. Noctis is also the main character of the manga adaptation of Final Fantasy XV.
Noctis was parodied by Bkub Okawa, author of the comedy manga Pop Team Epic alongside Ignis as both characters received super deformed designs that parodied the two main characters from that series.
