The organization that instigates crimes in Mega Man Battle Network is WWW, short for World Three.
WWW is the criminal network behind the incidents Lan Hikari and MegaMan.EXE investigate. Its activities include infecting computer networks with viruses, disrupting essential services, and stealing or manipulating important information. The organization turns ordinary infrastructure into danger zones, making cyberspace central to the game's story.
The name is a play on the World Wide Web, fitting the game's alternate future where people interact with electronic devices through NetNavis. WWW is led by Dr. Wily, a recurring Mega Man antagonist whose role is adapted to the Battle Network continuity.
Players often mix WWW up with other syndicates from later entries. Gospel is the principal organization in Mega Man Battle Network 2, while Nebula operates in Mega Man Battle Network 4 and 5. WWW returns in several other Battle Network games, including the third and sixth mainline installments, but it is the original game's criminal organization.
