Computers have turned the world into a bright and shiny utopia, but there's always trouble in paradise. A sinister organization by the name of World Three has appeared, and they've 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.

MegaMan is on the run! Thanks to the nasty work of a mega-imposter, DenTech City's greatest virtual hero is Public Enemy No. 1. If he can reach Netopian Special Intelligence Headquarters, he just might be able to clear his name... or he could find himself in even more trouble! Through it all, MegaMan has warned Lan to stay in school and out of danger. But how can Lan stand by when his best friends is in trouble?

Not long ago, MegaMan was the most infamous criminal in the Net, framed for cybercrimes he didn't commit. Now he and Lan are the Net's only hope! The treacherous Dr. Regal has unleashed the ultimate manifestation of Dark Power, an entity known as Nebula Grey. With the Netopian army down, MegaMan and a handful of allies have to stop Nebula Grey... or be deleted forever!

A new force has been unleashed from the darkest, wildest realms of the Net - a menace more dangerous than anything DenTech City has ever faced. What is it? MegaMan himself! Transformed by the mysterious "Beast" program, MegaMan has developed the unwelcome power to turn into a rampaging monster.

A new force has been unleashed from the darkest, wildest realms of the Net - a menace more dangerous than anything DenTech City has ever faced. What is it? MegaMan himself!

Armed with a deadly weapon called The Dream Virus, an evil genius by the name of Mr. Wily is determined to take over the Net. Now it's up to MegaMan and his pal ProtoMan to squash the fiendish mastermind. If they fail, DenTech City and the rest of the world will be permanently deleted!

Venturing deeper and deeper into the murky UnderNet, MegaMan and Lan Hikari come face to face with PharaohMan - a 20-thousand-year-old relic from a long-forgotten civilization. At his command, PharaohMan possesses the four holy warriors - each one as powerful as MegaMan himself!

To the rescue comes a hyperactive little kid named Lan Hikari. Teaming up with MegaMan, his specially programmed NetNavi, he's DenTech City's top boy hero. With each new NetBattle, Lan and MegaMan get stronger and stronger. But when the pair achieves PerfectSynchro, the pint-sized NetNavi flips out. Now the NetPolice must do the unthinkable: they must destroy MegaMan before he destroys the world!

When trouble comes to DenTech City, the authorities turn to a spazzed-out fifthgrader for help. That's because they know Lan Hikari is hooked up to MegaMan, the most powerful NetNavi in the Cyber Network. Synchronized together, Lan and MegaMan have become DenTech City's mightiest heroes.

A strange and dark aura has surrounded all of DenTech City. The Dark Forces have arrived and they're making a bid to destroy the brick-and-mortar megalopolis. Just when things look their worst, MegaMan suddenly and unexplainably appears. What the heck is going on?! Everyone knows the Net Warrior can't exist in the real world. Has MegaMan's network transmission gone completely phooey?

MegaMan's fiercest enemy Bass has returned and he's more powerful than ever. Vested by the Dark Power, Bass has fused with CyberBeast Grave to become DenTech City's worst nightmare. To save the day, MegaMan and ProtoMan must come together using the SoulUnion program. Apart, the two friends are no match for the new Bass. But together, there's a chance they can smash their archenemy to smithereens.

Enter SearchMan! When his entire battalion of warriors is wiped out by a MegaMan impostor, he comes to DenTech City looking for the real MegaMan. The surviving Net warrior is big and bad and he won't rest until he's exacted his revenge.
