It's the year 200X and everyone in Den Tech City is plugged into the Net. But living in cyberspace isn't always fun and games. High-tech crimes and pesky viruses are always a big problem for the authorities. Thank gookness for MegaMan and his NetOperator, Lan Hikari. Together, they do their best to keep their hometown safe from being permanently deleted.

Venturing deeper and deeper into the murky UnderNet, MegaMan and Lan Hikari come face to face with PharaohMan - a 20,000-year-old relic from a long-forgotten civilization. At his command, PharaohMan possesses the four holy warriors...each one as powerful as MegaMan himself! Quickly, the cobalt-coloured NetNavi figures out the score. If he can defeat each of these warriors, he'll be able to wrestle their collective strength away from PharaohMan. With his pal GutsMan at his side, MegaMan is ready for a full-tilt fight. If he can defeat the fearsome foursome, he will be the strongest NetNavi in DenTech City!
