Mega Man Battle Network (series)

In the year 20xX, the internet has become integrated with every piece of electronic equipment in existence (from TVs to ovens), and people carry around hand-held devices known as a Personal Exploration Terminal (PET). These devices act as phones, pagers, instant messengers, news beams, and hacking devices all rolled into one. Additionally they are able to be customized with a “NetNavi” or a human-like personality that can be anything the owner desires.

A fifth-grader named Lan (光熱斗 Netto Hikari) has a NetNavi named MegaMan.EXE (Rockman.EXE)—a virus-fighting blue-suited cyber personality who is also Lan’s best friend. Although MegaMan.EXE has no body (unless the PET device itself counts), he can wander around in cyberspace and explore computer systems as if they were alternate worlds. Together Lan and MegaMan.EXE (also known as just MegaMan) cooperate to fight off hackers and viruses.

Trivia
