Koh is a supporting character in the 2011 anime series Wolverine, operating as a hardened criminal figure deeply embedded in the underworld of Madripoor. He leads a local gang and possesses an intimate knowledge of the city's hidden geography. His primary motivation is revenge against Kurohagi Hideki and Shingen Yashida, with whom he has outstanding personal scores to settle. Koh first appears in the eighth episode, where he forges a tactical alliance with Logan. He offers to guide the mutant to the heavily fortified Dragon Palace in exchange for Logan creating a massive diversion. Koh intends to use this chaos to infiltrate the palace with his men through a secret tunnel they have spent years excavating. This alliance is strictly transactional and pragmatic, born from a shared enemy rather than mutual trust. Koh is driven by dark, consuming thoughts of vengeance, which fuel his participation in the dangerous plan. He does not possess superhuman abilities but relies on his cunning, strategic patience, leadership of his gang, and proficiency with knives. He joins the final assault on the palace and directly confronts Shingen, though his assassination attempt fails because his opponent is wearing concealed protective armor. Koh does not undergo a significant personal transformation; his role remains that of a grim underworld facilitator. His most notable contributions to the story are his geographic expertise, specifically the knowledge of the perilous Hell Road and the secret tunnel, which provide Logan with the critical path needed to storm the heart of his enemy's fortress.
