Oil Man is one of the six Robot Masters from the Mega Man 3 (PC) computer game for DOS and is part of the CRORQ series of Robot Masters. This version of Oil Man is not the same as the Oil Man designed by Dr. Light and reprogrammed by Dr. Wily in Mega Man: Powered Up.
Oil Man resides on an off-shore oil platform and is equipped with an oil-shooting arm cannon (it shoots high-pressured oil in an attack called the Oil Stream). He is very fast and mobile, but he is weak against the sharp blade projectiles of the Blade Launcher used by Blade Man.
