Marcus Allen (マーカス・アレン) was a citizen of West City, a former reporter, and the ex-best friend and first victim of Ryan Harper. During a trip to the Harper Institute of Science and Technological Fields, Marcus and Ryan were involved in an accident and sent to the hospital.

Afterward, Ryan was rejected and shunned by everyone, including Marcus himself. This lead to Ryan losing his sanity and killing Marcus, thus beginning his crusade to kill every version of Marcus.
