Summary
Knuckleduster is a shrewd vigilante in his mid-forties who patrols the rooftops of the Naruhata district alongside fellow vigilantes Pop Step and The Crawler. Operating without a Quirk, he dedicates himself to protecting local citizens and combating the dangerous illegal drug known as Trigger, which empowers many of the villains he faces. Despite lacking any physical enhancement abilities, his raw strength and durability are so exceptional that Pro Hero Shōta Aizawa briefly mistook him for someone with a physical-type Quirk. He compensates for his lack of superpowers with elite hand-to-hand combat skills and sharp street smarts. During battles, Knuckleduster quickly analyzes an opponent's Quirk to identify vulnerabilities, exploiting these weaknesses through rapid strategic thinking. For his patrol, he relies on standard equipment, including a grappling hook and a pair of brass knuckledusters.
