Mega Man (known as Rockman in Japan) is a Japanese science fiction video game franchise developed and published by Capcom, featuring the protagonist of the same name. The original game was released for the Nintendo Entertainment System in 1987, and spawned a franchise that expanded to over 50 games on multiple systems. As of July 2024, the series has sold 42 million units worldwide. Mega Man has been popular among gamers and has been reimagined and evolved as a video game character for over 30 years.
The main series consists of eleven games, the standalone Mega Man & Bass, the spin-off Game Boy series (released in Japan as Rockman World), and various ports, remakes, and compilations. The core games in the franchise have all been set in a single continuity; the storyline of the "classic" series is succeeded by the Mega Man X, Mega Man Zero, Mega Man ZX, and the Mega Man Legends series. This timeline excludes the spin-off Mega Man Battle Network and Mega Man Star Force series, both of which take place in an alternate universe where the internet flourished rather than robotics.
