Noctis Lucis Caelum, nicknamed Noct, will be a playable character and the protagonist of Final Fantasy Versus XIII. He is a prince, the last heir to a dynasty ruling over the last kingdom to control crystals, and from his throne, defends his kingdom from marauders and barbarians who seek to conquer the city and claim the crystals by force. He has a number of companions, including his driver and a fugitive, and his family is known to operate in a similar manner to the modern-day mafia. Though he doesn't wish to fight her, circumstances force him to do battle with Stella Nox Fleuret, and he is also speculated to be opposed by a mysterious man robed entirely in white.

Noctis displays unearthly skills in battle, wielding a variety of weapons including swords, spears, axes, and firearms, among others, though his primary weapon appears to be a falchion fashioned with an engine at the hilt. He can conjure the weapons into the air and wield them by hand or by telekinesis, through the power of the Crystals, allowing him to form a wall of weapons which can act as a shield. He has also displayed the ability to teleport, seemingly to the locations of his weapons, allowing him to throw one of his weapons a great distance and reappear where it lands seconds later, the weapon in hand. In battle, his hair and eye colors change depending on which weapons and abilities he uses, though the reason for this has not been revealed.
Noctis is said to be a very shy person but tries to hide it by "acting cool," as seen in the TGS footage where he and Stella had a short conversation about the two of them seeing a form of "light". Stella goes on to explain a legend of Tenebrae, that when a person is able to see the "light", they will receive the powers of the dead from the Goddess Etro. The footage was shown to give the people an idea of the two characters' personalities. In the footage, Noctis is also able to speak briefly with a painting of the goddess, asking who she is.
