Megaman

In the year 200X, aged scientist Dr. Thomas Light (Dr. Right in the Japanese version) began a scientific project named "Robot Master" in order to create the first robot capable of thinking and reacting to simple commands. This android would have been used to supervise the work of other machines and coordinate them, hence the codename.
The first robot designed to accomplish this task was Protoman (Blues), who had the ability to coordinate small robot units for military purposes. Despite the testing program's good results, Protoman escaped leaving no trace of his whereabouts.

After this unfortunate accident, Dr. Light decided to create two robots called Rock and Roll, hoping that providing each one of them a peer would avoid any possibility of escape. These two androids had different purposes: Rock, with his ability to mimic the usage of a tool only by seeing it at work, became a valuable lab assistant, while Roll was created as a housekeeper.
Thanks to the data acquired by these two robots, Dr. Light was then able to build six robot in order to help mankind - Cutman, a woodcutter robot, Gutsman, used as an escavation and construction robot, Elecman, supervisor of atomic powerplants, Fireman, built for waste disposal purposes, Iceman, able to explore wastelands covered by ice and snow at extreme freezing temperatures, and Bombman, mainly used for demolition purposes. Every one of them possessed the same abilities of Dr. Light's previous creations as part of the Robot Master project, thus being practically independent. The doctor's contribute to science was later recognized by the world science community and he was awarded with the Nobel prize for Physics.

However, Dr. Albert W. Wily, who at that time was a colleague of Dr. Light, grew jealous of his partner after his project was overshadowed by the success and the popularity Dr. Light earned.
One day he found a badly damaged, dying Protoman and decided to repair him using the schematics of his own project, thus creating from him the police robot named Sniper Joe. Amazed by his ability to disassemble and reprogram Dr. Light's robots, Wily decided to take revenge against his colleague. He then went to Dr. Light's lab and stole his six robots leaving only Rock and Roll, thinking that they would have never been able to accomplish his world-domination desire. After reprogramming the other robots he set them against the city.

It was precisely at that time that Rock offered himself to Dr. Light in order to be reprogrammed as a fighting robot, becoming the great Megaman (Rockman) we all know.
His upgrade enabled him to copy the other robot masters' weapons. Megaman was also given an arm cannon which shoots plasma bullets, commonly known as "buster", and the ability to teleport from place to place. Dr. Light has also been building for Megaman some other gadgets to help him throughout his journey like Rush, a canine companion robot with the ability to merge into useful means of transportation such a submarine or a jet.
