O'Clock wears a full body suit and a case that covers his eyes and half of his face, also uses gloves and boots.
His suit has several lines around the arms, legs and torso. On his shoulders he has what appears to be his symbol.
Little is known about his personality.
He was a veteran fighter against the crime of the last generation. But news of his exploits stopped over the years, at one point he had a pupil.
Acceleration (加速,Kasoku?): The Quirk allows him to accelerate to extreme speeds to the point that to him it looks like nothing is moving. The quirk does have a cool down time after using it and can only be used for a few seconds.
When his quirk is active he gets covered in lighting this could be a reference to the Flash from DC comics.
His symbol looks similar to the symbol for capsule corp from Dragon Ball.
