Megaman, known as Rockman (ロックマン, Rokkuman) in Japan, is the first video game in a long running series developed and published by Capcom in 1987 for the Nintendo Entertainment System/Famicom. It stars the titular hero Megaman, a boy robot created by Dr. Light to defeat Dr. Wily and his six Robot Masters. Using his Mega Buster, Megaman travels to various themed locales defeating the Robot Masters and receiving their weapons along the way. It revolutionized platform gaming at the time with selectable stages, selectable weapons, and music still lauded to this day. It also spawned several sequel series, including Mega Man X (which took place a century after the events of the original Mega Man series and involved the main character as well as his friend Zero trying to stop Terminator-esque revolts by sentient robots known as reploids led by Sigma), Mega Man Zero (starring Zero in a post-apocalyptic world where reploids are being driven to extinction by a "utopian" government known as Neo Arcadia, which is later taken over by a madman known as Dr. Weil who was responsible for the world being destroyed in the first place), Mega Man ZX (taking place a century after the events of Mega Man Zero where Weil survived as a sentient rock known as Biometals and the player generally has to fight against several "Mega Men", which is redefined as people who can wield biometals who wish to use Model W, the biometal in question.), and Mega Man Legends (taking place significantly long after the events of the Mega Man ZX series, where humanity is all but extinct and replaced by biological constructs known as Carbons).
It was later released on Mega Man: The Wily Wars for Sega Genesis, as well as the Japanese collection game, Rockman Complete Works in 1999 for the Sony PlayStation. In 2004, it was re-released in the anthology game, Mega Man Anniversary Collection for the GameCube, Xbox, and PlayStation 2. There is also a remake called Mega Man Powered Up (Rockman Rockman in Japan) for the PlayStation Portable. It features full 3D graphics (while maintaining it's classic 2D gameplay) and extra stages were added, making the Robot Master count eight instead of the original six. It also features a stage level editor. The characters were rendered in a "super deformed" art style(with overly large heads and short extremities). Keiji Inafune claimed in an interview that he originally planned to make Mega Man look this way, but couldn't, due to the hardware restraints of the NES
