Marcus {route 06}

Clayton is a cyborg with yellow skin, shaggy white hair, and a short white beard. Being partially robotic, many parts of his body are robotic, including the right side of his face, part of his left arm, his right leg, and his right hand, which has been replaced by his trusty railgun.

He wears an open dark purple jacket, a black tank top, and blue jeans with a noticeable rip in the leg. Clayton's past, like most of the other survivors, is largely unknown. It was revealed that his "Past Scars" skin is canon, meaning he served in the military in his youth and likely suffered serious injuries, leading to robotic enhancements and possible discharge. He also served alongside Marcus until he suffered an injury, for which Marcus blames himself. This is supported by his dialogue with Ethan, in which he says that before the infection, he "barely used his hand cannon."

Marcus is an adult man with yellow skin, a bald head, and a small black beard on his lower jaw. He wears only a military cap. He wears a light green shirt, brown gloves, and some hair on his arms. He wears a brown belt with yellow buckles, camouflage pants, and brown boots. He's self-assured and always ready to protect his own. He promised himself he'd protect Clayton with his own life. Marcus fought against another country with Clayton, but when he could have saved Clayton's life, risking his own, he chose to leave because he was afraid of dying. He blames himself deeply, but doesn't want to discuss this with the current Clayton. He's deeply concerned about Clayton's well-being and wants to provide him with the protection he couldn't give him back then. He's so afraid of completely losing Clayton's trust that he can't even yell at him or use his usual commanding voice. He's always stern and serious with everyone, but Clayton is an exception.
