Volume 1

 * The story is set in an ambiguous year in the 21st century ("20XX AD").
 * The Net has become humanity's primary means of communication, commerce, and even crime.
 * Users are able to "jack in" to the Net and other computerized devices, and explore their various aspects using program avatars called "NetNavis (Network Navigators)" as if they were physical locations.
 * The Net and the inner workings of computers are displayed as a virtual world with which computer programs of all varieties, as personified in a humanoid form, can interact. Users often do so by accessing their NetNavis via a "PET (PErsonal information Terminal)" device.
 * Lan Hikari is a fifth grader in the town of ACDC. His father, Dr. Yuichiro Hikari, is one of the world's top scientists and NetNavi researchers.
 * Not long into the story, Lan and his NetNavi MegaMan.EXE take it upon themselves to solve various criminal cases around ACDC involving other Navis and their operators.
 * Some of the confrontations with the various criminals involve desperate, life-threatening situations including a bus rigged to explode, oxygen being cut off at a large party, the entire city's clean water freezing, and school students being re-educated as mindless slaves.
 * The duo continuously crosses paths with Eugene Chaud, an official "NetBattler" commissioned by the government to investigate crimes on the Net. Chaud and his NetNavi ProtoMan.EXE act as rivals to Lan and MegaMan.EXE.
 * The protagonists eventually learn that the criminals are all connected to an organization called the "WWW (World Three)". The WWW intentionally infects computer networks with computer viruses so as to hinder their normal operations and hack vital information. The group is led by Dr. Wily, a former colleague of Lan's grandfather.
 * While working together, Wily had specialized in robotics while Lan's grandfather specialized in networks, which eventually led to NetNavis.
 * The government cut Wily's funding, opting instead to pursue Hikari's NetNavi project.
 * Wily's goal throughout the game is to collect four super programs with which the "LifeVirus" may be constructed. The LifeVirus is a nearly indestructible virus capable of wiping out the Net and all associated devices.
 * The protagonists infiltrate the WWW, but MegaMan.EXE becomes disabled. Chaud arrives and gives Lan a batch file from Dr. Hikari to restore his Navi.
 * After receiving the file "Hub.bat", Lan questions his father about the name.
 * It is revealed the MegaMan.EXE is actually a unique Navi made by Lan's father. When Lan's twin brother, Hub, died at a young age, Dr. Hikari transferred Hub's consciousness into the NetNavi MegaMan.EXE. This created a special physical and virtual bond between the two brothers.
 * In the end, Lan and MegaMan.EXE manage to defeat Wily, destroy the LifeVirus, and restore peace to ACDC.

Volume 2

 * The story opens with the world in a time of peace following the defeat of the organization known as the WWW.
 * However, NetCrime, as perpetrated by a NetMafia organization known as Gospel, is on the rise.
 * Once again Lan Hikari and his NetNavi MegaMan become involved and work to defeat Gospel's plot to destroy society.
 * NetNavis Operators are given the chance to become City NetBattlers, a lesser form of an Official NetBattler, which Lan does, allowing him to travel around the world, both in cyberspace and in real life. In doing so, Lan befuddles Gospel's attempts to collect four particularly powerful computer programs, called simply SuperPrograms, on numerous occasions.
 * However, Gospel is finally successful and uses these programs, in combination with computer bugs, to construct a SuperNavi of immense power. This Navi is a duplication of Bass.
 * However, after fighting Megaman the Bass copy destabilized and transformed into a gigantic, wolf-shaped super Multi-bug Organism (Also referred as Gospel) that heavily resembles Gregar.
 * The energy needed to create this Navi causes unusual radiation, blending the Net and the real world together.
 * This radiation eventually paralyzes Lan, effectively making him incapable of operating MegaMan, however the latter puts the two into full synchronization so that Lan may control MegaMan by thought and emotion.
 * During the final battle it is revealed that the leader of Gospel is Sean Obihiro, a child who felt neglected by and resentful of society after his parents died in a plane crash.
 * After defeating the Multi-bug Organism Gospel, Lan promises to be the boy's friend after he has paid for his crimes.
 * Bass is later seen destroying copies of himself, and shows anger toward the human that made them (implying to Sean). He swears he'll exact his revenge on the humans and then disappears.

Blue/White

 * Doctor Wily has reformed the evil organization WWW and now seeks to release Alpha, an evil prototype version of the Internet that was locked away before the current Internet was set up. To release him, Wily needs the passwords, referred to as TetraCodes, to the firewalls Alpha is trapped behind, which are hidden in secret locations.
 * A tournament called the N1 Grand Prix is being held, supposedly to determine who is the best NetBattler.
 * It is later revealed to be part of the plan for Wily to steal the TetraCodes, and the WWW attacks between rounds.
 * Lan Hikari and his NetNavi, Mega Man, have to fight NetNavis sent by Wily and attempt to defend the TetraCodes from Wily, but he manages to retrieve them anyway with the help of Bass, and uses them to release Alpha.
 * Lan and Megaman confront Wily immediately after he releases Alpha, and battles Bass.
 * After Bass is deleted, Alpha consumes Dr. Wily and proceeds to infect the whole of the Internet with his coding.
 * Megaman battles Alpha, and is able to defeat him.
 * As Alpha begins to delete, the network in the area begins to crash as Alpha attempts to absorb everything to save itself. Unfortunately, this includes Megaman and Lan.
 * In an attempt to allow Lan to escape, Megaman overloads, sacrificing his life to save Lan.
 * Later, Lan's father manages to recover Megaman during a salvage operation of the affected network location, and is able to revive him.

Red Sun/Blue Moon

 * NAXA scientists have discovered a massive asteroid speeding toward the earth that, if made contact with, would end all life on earth.
 * Lan Hikari and MegaMan.EXE go shopping with their father. While in the electronics district, they find themselves pitted against a NetNavi known as ShadeMan, portrayed as having strong dark powers.
 * Upon defeating ShadeMan, he disappears, dropping unknown data. It is revealed to Lan and MegaMan to be a DarkChip, a program described as unleashing great power at the cost of the Navi's soul (their goodness and well-being). The duo are warned to never use it under any circumstances.
 * The scientists, who are now joined by some of the best scientists and researchers of various countries, including the duo's father. They come to the conclusion that the best way to avoid impact with the asteroid is to use a laser to move it off-course.
 * The, after the ShadeMan incident, Lan and MegaMan participate in the Den Battle Tournament, the local NetBattle tournament, and become the champions.
 * After completing the tourney, they return home to find it burglarized by someone connected to the DarkChip. Upon investigation, they discover that the DarkChip Syndicate Nebula was behind the attack of their home, looking for the DarkChip the two possess.
 * After defeating a Nebula member in battle, he warns the duo that the syndicate has their eye on them and the DarkChip.
 * With no leads to go on, the pair decide to go to the amusement park, only to find the animatronics going haywire. Lan and MegaMan find ShadeMan in one of the animatronic animals. In order to best ShadeMan, MegaMan has no other option but to use the DarkChip.
 * Now, without the DarkChip or ShadeMan, the duo decide to enter the Eagle/Hawk Tournament held by the amusement park. The team emerge victorious once again.
 * After the tournament, they meet LaserMan, the leader Navi of Nebula, who shows MegaMan the DarkSoul lurking within him now that he has used a DarkChip.
 * Meanwhile, the scientists fire the laser at the asteroid, but it fails. One of the scientists, Dr. Regal, claims to have an idea and asks for a world-class Net Operator and Navi.
 * Naturally, Lan and MegaMan are invited to the Red Sun/Blue Moon Tournament, a competition explained as putting together the best of the best of NetBattlers.
 * After winning the tourney, the duo are taken to NAXA and are briefed on the situation. It is explained that the asteroid has a computer in it and can be steered away from the planet.
 * Before Lan has the chance to send MegaMan to the asteroid, Dr. Regal reveals himself as the leader of Nebula and had been planning all along to use the asteroid in his plan for world domination.
 * Still, Lan is able to send MegaMan, where he once again meets LaserMan, as well as Duo, the Operating System of the asteroid.
 * MegaMan defeats both of them and convinces Duo that the planet is worthy enough to not be destroyed.
 * The asteroid leaves, and Regal appeared to have committed suicide in order to avoid legal prosecution. Once again, Lan and MegaMan have saved the world from the latest crisis.
