Mega Man is a fictional battle robot and champion of justice of the year 200X from the game series, Mega Man. He was built by Dr. Light alongside Roll to keep the good doctor company, but when former associate Dr. Wily turned evil, Mega Man volunteered to transform himself into a fighting robot to save the world. As one of the four faces of gaming, he is usually deemed as the darkest role, being the patron for the corrupted, as Capcom has been slowly poisoning his franchise to the point death is only merciful.
Mega Man's role in the original story is to battle the mad scientist Dr. Wily and his ever-growing army of robots, and stop them from taking over the planet by using their own special abilities against them. Utilizing his Mega Buster arm cannon, and his ability to copy a defeated robot's special weapon. Mega Man must travel the world and traverse harsh environments in order to bring Wily's menace to an end. With the help of his creator Dr. Light and his assorted cybernetic companions, Mega Man's eventual goal is to one day achieve "everlasting peace".
His most notable appearances have been within his own self-titled games, beginning with Rockman for the Nintendo Famicom in 1987. This, and all future Mega Man games released in North America and Europe, would bear the title "Mega Man" due to Capcom USA's early decision to change the name. Prior to decision on the name "Mega Man" which was proposed by Joseph Morici, Capcom had even considered the name "Rainbow Man" as a possible title due to the nature of Mega Man's color change when using different Robot Master weapons. Nearly all of the classic series Mega Man titles have been two-dimensional sidescrollers involving horizontal movement through various levels. This mechanic continues even on titles developed for high performance platforms, such as the Sony PSP release of Mega Man Powered Up, which features 3D graphics, yet movement to both the background and foreground is restricted. The main series on both the NES and Nintendo Game Boy would follow this approach in the design of every game developed on those systems, and set the standard for all platformer Mega Man games to come. Mega Man himself has evolved very little cosmetically since his initial release, but has often been given new techniques in each game. The New Mega Buster, for instance, which was introduced in Mega Man 4, allowed him to charge up a shot. The slide was introduced in Mega Man 3. It was these which were needed in order to help him exceed any new challenges added by the level designers. However, in Mega Man 9 Mega Man's abilities were restricted back to that of the original game.
Mega Man has made appearances in several game projects outside of his original series. He appears as a playable character in Marvel vs. Capcom and Marvel vs. Capcom 2 assisted by Rush and Beat as a representative of the Capcom brand. Mega Man makes another fighting game appearance in Street Fighter X Tekken but as an aged, obese depiction of the character on the North American box art of Mega Man, complete with pistol. Here he has the name "Mega Man" even in the Japanese version. Mega Man will also appear as a playable character in the next installment of Nintendo's Super Smash Bros. series, utilizing abilities copied from various Robot Masters.
