Cor Leonis

Cor Leonis is a guest character in Final Fantasy XV. He serves as a companion to Noctis and is one of the three best fighters in the Kingdom of Lucis. As such, he is known as the "Immortal Shogun" to many and is known as the "Marshal" by Noctis and his group, due to his status in the Crownsguard, the royalty's personal guard in Lucian Military.

Appearance
Cor is a middle-aged man with short, brown hair. He has light blue eyes and wears a black, collared jacket with skull-shaped buttons. Cor wears a black, skull-print shirt, black trousers, and black boots with red soles.

Personality
Cor is a stubborn, stern, no-nonsense military man who has sworn loyalty to King Regis Lucis Caelum CXIII and his country. He is strict with Noctis and his friends, and while he does not always see eye-to-eye with them, he is duty-bound to watch over them.

Story
After the fall of Lucis's capital city Insomnia, Noctis gets a call from the Marshal, who tells Noctis for him and his group to meet him at Hammerhead. He confirms the news that the king has perished to a shocked Noctis. At Hammerhead Cid tells Noctis Cor has gone to the Royal Tomb in the local Leide area. Noctis finds Cor there, who explains Noctis his next mission of collecting the weapons of the past Lucian kings to gain the power to reclaim his throne. Noctis finds it difficult to concentrate on this new objective in the light of the recent events, but Cor explains to him the reasons Regis had sent Noctis away from the city and directs him to the next tomb.

After Noctis collects his second weapon, Cor calls him and tells him of their plan to demolish a base that the Niflheim Empire is building to block passage to Duscae. Noctis meets with Cor outside the base, and while Noctis's friends go off to create a diversion, Noctis and Cor infiltrate the base together and take out its magitek forces. After the road to Duscae is open, Cor is satisfied that Noctis is strong enough to continue on his mission without his help, and departs.

At some point during Noctis' ten years in the spirit realm, Cor became a daemon hunter.

Gameplay
Cor joins as a guest party member in Chapter 2 for the first Royal Tomb and for the imperial base at the area. He is on LV52, fights with a katana and has a set of abilities that allow him to coordinate with Noctis, much like Gladiolus, Ignis and Prompto. His equipment cannot be changed, but the player can view his gear from the menu.

Voice
Cor is voiced by Hiroki Tōchi in the Japanese version, who had previously voiced Noctis's chauffeur before being recast. He shares his Japanese voice actor with Yaag Rosch from Final Fantasy XIII and Zhuyu Voghfau Byot from Final Fantasy Type-0. In the English version of Final Fantasy XV, Cor is voiced by Matthew Mercer. He shares his English voice actor with Trey.

Trivia

 * It was decided that Cor would be 42 years old because, in Japan, 42 is an unlucky number. The Japanese believe men of this age suffer great misfortune.
