Captain Nick Reyes is the main character of Call of Duty: Infinite Warfare.
He is portrayed by Brian Bloom.
Reyes is an operative of the Space Combat Air Recon (or SCAR for short), a division of the United Nations Space Alliance and Solar Associated Treaty Organization, who's been given command of the UNSA Retribution after its original Commander had been killed in a deliberate collision with the Settlement Defense Front Supercarrier Olympus Mons to drive it away.
Reyes had commanded the Retribution and its forces on numerous notable operations, mostly including the boarding of the Olympus Mons, which resulted in the assassination of SDF 8th Fleet Leader Salen Kotch and the seizure of the Olympus for the final strike against SDF on their Orbital Shipyard on Mars.
Reyes was killed when he ordered his partner and closest friend Nora Salter to fire on his position in the Shipyard. Despite causing his death, this action also destroyed the SDF Shipyard, severely weakening the SDF and cutting off their methods of space travel, meaning that they can no longer mount any attacks on Earth or its supported worlds.
