About Rockman World 5
Rockman World 5 for the Game Boy begins with a peaceful outing interrupted by a hostile robot named Terra. He declares his intent to conquer Earth alongside his forces, the StarDroids, and defeats Mega Man with superior weaponry.
After this defeat, Dr. Light modifies Mega Man's systems, granting him a new weapon called the Mega Arm. This upgrade allows him to fire his entire fist as a projectile. The objective is to combat the StarDroids, who have nearly taken over the world, with the assistance of a robotic cat companion named Tango.
