Sergeant Marcus Michael Fenix ES is a former Gear soldier in the Coalition of Ordered Governments army. A legendary war hero, Marcus served with distinction in the Pendulum Wars, which earned him the Embry Star, the COG's highest military award, for his actions during the Battle of Aspho Fields. He is also a convicted "coward" for his actions at the Battle of Ephyra. Like the rest of humankind, he saw everything change on Emergence Day. Marcus bravely fought against the Locust for ten years until the Battle of Ephyra, where he abandoned his post to rescue his father, Professor Adam Fenix, but could not reach him in time. With his father presumed dead, Marcus was tried for dereliction of duty and sentenced to 40 years in Jacinto Maximum Security Prison. He was incarcerated for four years before being released by his longtime friend, Dominic Santiago. Marcus was later promoted to replace Lt. Minh Young Kim after the squad leader's death. Along with the rest of Delta Squad, he successfully detonated the Lightmass Bomb and destroyed much of the Locust Hollow. With his reputation restored, Marcus continued fighting against the Locust, culminating in the Sinking of Jacinto. After the COG moved to Vectes, Marcus fought against Stranded insurgents and the rising threat of the Lambent. After the COG collapsed under the constant struggle to survive, Marcus and the rest of Delta banded together with other Gears and civilians aboard the CNV Sovereign, seeking a way to survive in the new world. Eighteen months later, Chairman Prescott returned with the startling news that his father was alive. Marcus led humanity to victory over the Locust and the Lambent, but was at a loss of what to do next after losing both his father and Dom along the way. He was in a relationship with Anya Stroud, and was the father of James Fenix.
