Michael is a Regular and a Wave Controller who first appears on the 25th Floor of the Tower during the events depicted in Tower of God: Return of the Prince. He joins Khun Aguero Agnes’s team under the guise of a quack doctor, earning the nickname “missionary” or “the evangelist” among the group. Among the team members, he is ranked fifth in overall ability, counting only the Regulars and excluding both Khun and Rachel.

In reality, Michael is an associate of FUG, the criminal syndicate that opposes the ruling Jahad dynasty. He was specifically hired to infiltrate Khun’s team with the objective of assassinating Khun. This hidden allegiance places him in an antagonistic role, working against the interests of the main characters while maintaining a façade of cooperation and helpfulness. His personality is described as calm and opportunistic, often observed wearing a leisurely smile even as tensions rise within the group.

Michael’s motivations are tied directly to his FUG affiliation, acting as a covert operative rather than a driven, personal crusader. His role within the story is that of a mole, gathering information and waiting for the right moment to strike, which adds an element of distrust and danger to Khun’s team dynamics. He does not have any deep personal relationships; his interactions are primarily transactional, serving his mission. His notable ability is his mastery as a Wave Controller, a class that focuses on manipulating shinsu, the mystical energy of the Tower. However, specific techniques or feats of strength are not extensively detailed in the available material. Over the course of the Return of the Prince arc, his true nature is gradually exposed, leading to a betrayal that impacts the team’s journey.
