Maddox is a researcher and scientist affiliated with the Workshop, a mysterious organization within the Tower dedicated to advanced technological and shinsu-related research. He is described as one of the more morally ambiguous members of the Workshop, willing to pursue his research objectives without regard for ethical boundaries, including conducting experiments on human subjects without their consent. His primary area of work involves Living Ignition Weapons, a type of artificial weapon created by fusing living beings with ignition devices. Maddox was part of the team that originally developed this technology, and he later served as the manager and lead scientist in charge of experiments involving Kang Horyang and Beniamino Cassano, two subjects who were turned into Living Ignition Weapons. His role in the story is that of a supporting antagonist, operating behind the scenes during the Workshop Battle arc. He appears in the anime Tower of God: Return of the Prince as a figure connected to the darker side of the Workshop's activities. His personality is characterized by a cold, pragmatic dedication to his work, and he shows little concern for the suffering of those he experiments on. His motivations are driven by scientific curiosity and a desire to advance his research, regardless of the cost. In terms of relationships, he is primarily associated with his research subjects, Cassano and Horyang, as well as his assistant Sophia Amae, who works alongside him in the lab. He has no known significant character development within the anime, remaining a static figure defined by his role as an unethical scientist. His notable abilities are not explicitly detailed, but his expertise in shinsu engineering and Living Ignition Weapon creation marks him as a skilled and dangerous specialist within the Workshop hierarchy.
