It is the year 200X, and everyone is now connected to the Cyber Network. Individuals carry their own PET (Personal Terminal) and are paired with an artificial intelligence program known as a NetNavi (or NetNavigator). Computers have transformed the world into a bright and shiny utopia, yet trouble persists in paradise. Although the invention of the PET and NetNavis has brought significant benefits to the world, computer hacking, virus spreading, and other high-tech crimes are becoming a major problem. A sinister organization called World Three has emerged and vowed to destroy this technological wonderland. Enter our young hero, Lan Hikari, an intensely curious and cheerful fifth grader. Synchronized with his NetNavigator, MegaMan, he becomes a super-charged dynamo. Both in and out of the Net, Lan and MegaMan do their best to thwart World Three's never-ending quest to take over the world!
