Max (マックス, Makkusu) is a member of the Iron Knuckles clan. It has not been clear whether he is a high-ranking member or the leader of his clan. He is known as "Titan" Max ("タイマン" マックス, "Taiman" Makkusu), though his real name is Masafumi (マサフミ).
He is not a particularly large man with a buzz cut and a baby face.
- Since the Iron Knuckles clan has been described as fighters, Max is most likely a Warrior or Paladin.
