Regis Lucis Caelum

King Regis Lucis Caelum is the ruler of the Kingdom of Lucis, the father of the prophesized True King Noctis Lucis Caelum, and Wife of late Queen Aulea.

Personality

Regis, worthy of being considered the greatest king Lucis ever had, has full understanding of how to be the monarch beloved by all people. He treats his subjects equally. He cares deeply for his son and is distraught at the fact that his son will have to suffer the same burden Regis himself had to bear by maintaining the Wall. Therefore, he quickly agrees to allow himself to die in exchange for Noctis being the True King, finding solace in how his son will go down as the savior of Lucis. Regis, knowing Noctis's fate, does everything he can to ensure Noctis had a happy life before the time came for his destiny to be fulfilled, having Noctis attend normal schools and while he sacrificed himself so Luna can get the ring to Noctis, Regis also genuinely wanted her to be with Noctis. He trusts Gladiolus, Prompto, and Ignis fully in the task of taking care of Noctis and gives them advice on how they should allow him to choose his own path. Regis later is unable to stand and watch as Noctis is attacked by the rulers of Yore and hesitates for a while before finally taking on his Lucii form and landing the killing blow.

Powers and Abilities

• Magic: As the reigning monarch of Lucis, Regis, like all in his bloodline, is capable of wielding the divine powers of the Crystal, with him also having the Ring of the Lucii to enhance his powers. Regis could warp and phase through solid matter, which he incorperated in his battle style to dodge most attacks and quickly attack back, manifest weapons from thin air, and invoke Armiger to wield several weapons at once. Uniquely, he wields his own personal collection of weapons rather than the Royal Arms and shows no limit in maintaining Armigern with several unique techniques, such as launching the weapons at enemies, which he can either do in a straightforward manner or have them fire at enemies from several directions, raining down the Royal Arms from above, and also forming them into a defensive formation to block attacks; should said formation be broken, Regis can have the scattered weapons attack the enemy, making it unpredictable. but is capable of using Armiger without strain. He is also a powerful spellcaster capable of erecting durable magical shields around both himself and others that are impenetrable by bullets and even superhumanly strong foes have trouble breaking them as well as casting ranged elemental projectile spells without need of Magic Flasks or collecting energy from deposits, unleashing waves of flame, blocks of ice and strikes of thunder that home on the target, although he is also capable of blasting purple bolts of thunder and is able to channel lightning from his sword. He also can cast a holy-elemental spell where he creates several slashes of light. At one point, he is seen wielding sparkling flame while on his throne. He also could activate the Old Wall, commanding the statues of the Fierce and the Rogue to fight off Ardyn's attack and was able to grant a portion of his powers to the Kingsglaive to make them extensions of himself in protecting Insomnia. His most vital magical power is the ability to manifest and maintain the New Wall, a large magical barrier around Insomnia with the Ring, which he is able to dispel and reactivate it at will to allow others to enter and reseal Insomnia afterwards. However, the maintaining of the Wall for several years has severely depleted his life-force, to the point he is now weak enough physically to barely be able to walk without aid. In addition, his powers have also weakened to a notable degree, which was why he had no choice but to go along with the peace treaty of Nifleheim as he is incapable of commanding the Old Wall should the New Wall be broken through nor does he have the power to maintain the barrier for more than a few years or muster enough power to turn the tides on the side of Lucis. However, Regis can still use a surprising level of power despite such debilitation, as he still can use Armiger and use powerful spells to defend himself. Before his death, he is seen to be able to tap into the power of the Chrystal to generate a powerful protective barrier independent of his life to ensure Luna and Nyx's safe escape from the castle. Regis's specific power is the ability to regenerate himself by taking others vitality and can also sacrifice part of his own life-force to restore others, as his sigil Revitalize allows a Glaive to do so. He somehow can foresee the future, as he saw a vision of Noctis's possible future.

• Combat Prowess: While still a young adult, he is already an accomplished combatant capable of wielding swords, spears and shields with superb skill, able to defeat many monsters with ease. His mastery of swordsmanship and physical strength could wield a broadsword single-handed with great expertise and deliver swift combos as well as break through even deadly enemies guard with a singularly charged slash. With his spear, Regis can manipulate it deftly to effectively attack others from a distance and can accurately hit even higher targets. His skills with a shield can easily block and quickly counter with a strong bash. His prowess during his battle with Ulros was described as the most fantastic story Noctis ever heard from his father. With the Sword of the Father, Regis can perform swift sword combos. However, he has lost the ability to engage in combat due to how maintaining the Wall has greatly weakened his body to the point of needing a cane to walk. Despite his physical debilitations, however, Regis still retains a surprising amount of endurance, as he was able to retain consciousness after having been cut in the arm by Glauca and move around with aid from Lunafreya. He also had the reaction speed required to counter Glauca's boosted jump to block his blow with his weapons and was able to react in time to cast a powerful barrier to shield himself from Nifleheim's attacks after the truce was proven to be false. He even still had enough strength to cast a powerful protection spell that was not linked to his live, allowing it to remain even after he was killed, and was able to square off with Glauca magically for a time and he did not immediately die after being stabbed in the stomach twice, still being able to speak before finally succumbing.

• Master Leader and Strategist: Regis was known for many as being the greatest king Lucis ever had, proving himself to be an exceptional and wise leader and strategist capable of ruling all of Lucis effectively and leading it against Niffleheim, lasting far longer than any other country the Empire attacked despite the vastly superior technology possessed by Nifleheim, and he was able to easily deduce that the truce offered by Niffleheim was but a false promise and was able to manipulate it instead in a machievalan manner to suit his ends, allowing Insomnia to fall by willingly accepting the truce but also managing to evacuate most of the citizens and leave behind many soldiers to continue the war and most importantly allowing Noctis and his retinue to be safe through well-woven plans.
