Iwao Oguro (雄お黒ぐろ巌いわお, Oguro Iwao), also known as Knuckleduster (ナックルダスター, Nakkurudasutā) is the tritagonist of the manga series My Hero Academia: Vigilantes and its anime adaptation, a prequel of My Hero Academia.
He was originally a professional hero operating primarily in Japan under the alias O'Clock (オクロック, Okurokku). His quirk, aptly named Overclock, allowed him to increase the speed of his own perception to the point that the world around him appeared slow. Outwardly, O'Clock's quirk appeared as though it simply accelerated his movements, however it was his increased perception that allowed him to move at impossible speeds. Ultimately however, Iwao's quirk was stolen from him by the legendary villain All For One, leaving him quirkless.
