"Mega Man, also known as Rockman (ロックマン) in Japan, is a video game character, created by Akira Kitamura and designed by Keiji Inafune and is the title character of what has been referred to as the original Mega Man series developed by Capcom since 1987. Since then, he has become one of the company's primary original characters and continues to be one of the video game industry's most recognizable icons. Having appeared on many gaming systems since the Nintendo Entertainment System, Mega Man has had a wide gaming audience, and his games continue to evolve with the ever-changing hardware demands of modern gaming systems. Mega Man's fictional universe can be divided into seven categories, each featuring different variations and incarnations of a robotic boy hero. Although "Mega Man", or "Rockman", is usually the name used to describe only the original Mega Man from the classic series, it can also be used less specifically to describe the Mega Man series of fictional works, or the group of adherently named main characters within."
