The year is 200X, and everything electronic is connected by internet. In this world, there is no one, rich or poor, who does not own a PET (Personal Terminal), and there is not one PET that does not house a NetNavi, an AI Unit that has the power to delete Viruses and the like. Net Battles (where Operators battle their NetNavis) are popular in this era. That is where Lan Hikari and his NetNavi and best friend, Megaman come in. Striving to become the best NetBattlers, they fight Net Crime and protect the net and real world alike from the likes of the evil terrorist organization the World 3.
A mysterious young girl named Yai transfers into Lan's 5th Grade class. Impressed by her incredible wealth, Lan and Dex unwittingly find themselves trapped on the prococious little girl's estate. All the while, Maddy (an agent for World Three) and her maniacal NetNavi, WackoMan, unleash a devastating computer virus that causes the traffic lights in DenTech City to go haywire, creating an enormous traffic jam throughout the city! Lan jacks his PET into a traffic signal control computer, and discovers that the traffic management center has been infected by a computer virus. Will Lan and MegaMan be able to stop the panic?!
An eccentric guest lecturer, Mr. Higsby, has come to Lan's school. But the lesson he wants to teach isn't on the cirriculum! The nutty professor is on a quest to ""acquire"" all rare BattleChips from those he deems unworthy. His target... Yai. Using his NetNavi, NumberMan, Higsby takes over the school's control system and locks Yai, Ms. Mari, Dex, and Maylu in their classroom, then stages a lopsided NetBattle to obtain his precious prizes. Locked outside, Lan must find a way to send MegaMan to the rescue... before it's too late!
All the water in DenTech City has dried up! World Three has captured Tory and his father Dr. Froid and forced them to use their NetNavi IceMan to freeze the programs that control DenTech City's Waterworks. Lan and his friends rush to save the day, but with MegaMan encased in ice and the Waterworks decaying, can they possibly stop World Three in time to restore the city's water?
World Three's Count Zap is on a robbing rampage, only no one knows that his real target is the videogame that AyanoTech is about to release; if he can steal that, he'll make kids all over the world miserable. Lan and his friends learn of the sinister plot, and MegaMan goes up against ElecMan to stop it. But even with the help from Black Rose and WoodMan, will MegaMan be able to stop the ultra-powerful ElecMan?
Feeling like he's lost his inner fire, Mr. Match decides the only way to ignite it again is by defeating MegaMan once and for all. To lure him into his high-temperature trap, Mr. Match sends TorchMan out on a spree of overheating chaos throughout DenTech City. Maylu happens to be at the salon at the time, her hair gets fried, and Lan makes the mistake of laughing at her. Meanwhile, MegaMan hasn't replied to TorchMan's mayhem, causing Mr. Match to grow impatient. He sends TorchMan to challenge MegaMan directly, but the message stops at Roll, who also happens to be mad at MegaMan! Maylu and Roll decide to take on TorchMan, falling right into the terrible trap. Will MegaMan show up before Roll gets toasted?
The wildly popular TV personality and Yoga master, Yahoot, is in cahoots with World Three! The menacing mystic uses his powerful NetNavi MagicMan to take over the airwaves and hypnotize the devoted viewing audience--turning the entire town into animals! MegaMan jacks in to confront MagicMan, but things get pretty tricky. Our hero is outmatched by the nasty Navi. Just when MegaMan is about to receive the final blow, ProtoMan, controlled by the mysterious champion NetBattler Chaud, comes to his defense, and takes down MagicMan!
Lan and his friends are excitedly training for the upcoming N1 Grand Prix. Unfortunately, the members of World Three have secretly signed up for the competition and Mr. Wily plans to unleash chaos and mayhem at the event. To make matters worse, Higsby's NetNavi, NumberMan, goes berserk while Higsby is trying to upgrade him. Lan and MegaMan rush to the rescue, but it takes them so long to neutralize NumberMan that they almost miss the NetBattle competition! Thanks to Yai and her private jet, Dex, GutsMan, Maylu, Roll, Lan, and MegaMan arrive at the N1 Grand Prix just in time. Dex and GutsMan make a grand entrance at the competition as Chaud issues a challenge to Lan and MegaMan.
The N1 Grand Prix is well under way and Lan's first match is full of surprises! His opponent turns out to be Miyu, the mysterious fortune teller. She uses her powers to predict Lan and MegaMan's every move! Miyu's Navi SkullMan seems unstoppable as he attacks MegaMan with blinding speed. It's going to take a bit more wit and an uncommon usage of BattleChips to beat this bonehead!!
Just before their Net Battle competition at the N1 Grand Prix, Maddy insults Maylu and Yai in the trendy Souvenir Shop. Maylu vows right then and there to beat Maddy and her NetNavi, WackoMan, in their upcoming match. Unfortunately, during the NetBattle, WackoMan proves that he's as much a cheater as Maddy. But just when it looks like Roll is going to be defeated, Maddy makes a critical mistake and Roll seizes the moment! Meanwhile, Lan and MegaMan take on Mr. Match and TorchMan. Like Maddy, Mr. Match hatches a diabolical scheme to trick Lan into losing the match. Will World Three succeed in defeating the best Navis in the N1 Grand Prix...?
The N1 Grand Prix rages on, and TorchMan and MegaMan are locked in a heated battle (continued from previous episode)... It seems like MegaMan has the upper hand when Mr. Match downloads a nasty virus to take control of the solar panels on the roof of the Floating Arena's dome. He mercilessly channels the sun's rays into a beam that showers agonizing heat down upon Lan. As MegaMan and Lan suffer the scorching onslaught, Dex, Yai, and Tory jack in their NetNavis to vanquish the viruses one by one. Just as MegaMan's about to become toast, the gang clears the last of the viruses. The Dome opens up, and Lan and MegaMan turn in a blazing victory. Higsby and NumberMan fight the last battle of the day against sweet Sal and WoodMan. Thinking that they can easily defeat the flower girl, Higsby and NumberMan receive an ego smashing as Sal and WoodMan take them out in one blow!
It's time to party! Lan and the gang did so well in their first week in the N1 Grand Prix that Yai invites everyone to a fancy restaurant to celebrate. But when our heroes get to the restaurant, someone is sitting at the table reserved for Yai's family. It's Chaud! Pompous and condescending, it doesn't take long before Chaud insults Yai's family as well as Lan's NetBattling skills. Lan, defending his and Yai's honor, follows Chaud out of the restauraunt and into the night, where he challenges him to a NetBattle. Just as the battle begins, World Three unleashes a hoarde of viruses programmed to delete both MegaMan and Chaud's NetNavi, ProtoMan!
After his brutal battle with Chaud, Lan knows that the only way MegaMan will ever have a chance against ProtoMan is to master the legendary Program Advance technique. Lan recruits Dex to help him as they launch into an impromptu, intensive training course. Meanwhile, WhaleMan and SharkMan are going at it in the main Dome. To give Lan more training time before his upcoming match, Commander Beef holds out until the last possible second before unleashing SharkMan's devastating offense. Lan still can't seem to get it right, but the show must go on. In a ferocious fight with Yahoot and MagicMan, Lan tries the Program Advance once more, this time with better results. He wins the match, but just barely. Chaud and ProtoMan are up next against Count Zap and ElecMan. The World Three nasties pull a cheap trick, but Chaud and ProtoMan tap into the full power of the Program Advance and delete the cheaters from the competition!
Schoolmates Maylu and Tory, with their NetNavis, Roll and IceMan, battle it out in Week Two of the N1 Grand Prix! After Roll defeats IceMan, the games shift to a more challenging event: the Tag Team Matches, as pairs of NetNavis battle each other. First up, the mysterious StoneMan and BlasterMan challenge GutsMan and WoodMan. By the end of the match, it's revealed that StoneMan and BlasterMan are actually Mr. Wily's secret weapons. The two are revealed to be Solo NetNavis, which means they have free will and can battle without NetOps! After soundly defeating GutsMan and WoodMan, the two Solo NetNavis set their sights on MegaMan and SharkMan! With the undefeated StoneMan and BlasterMan at his side, will Mr. Wily succeed in finding the NetNavi with the Ultimate Program?
2 on 2 battles continue: MegaMan and SharkMan (Commander Beef) vs. StoneMan and BlasterMan. StoneMan and BlasterMan open a hole in the arena, and the four NetNavis are quickly sucked out of the ring and into a cyber world. They have 10 minutes to return to the ring, or they will be disqualified. Finally, MegaMan and BlasterMan return, and MegaMan is victorious. But Lan suspects that Commander Beef is Maysa in disguise.
The N1 Grand Prix moves into a special, second round of Tag Team competition when it is announced that two teams, which had previously been eliminated, can now re-enter the games. The two lucky teams are chosen by a computerized wildcard, but World Three rigs the competition so that Mr. Match and Maddy are selected, pitting TorchMan and WackoMan against MegaMan and Roll. Neither Lan nor Maylu are nervous about the match-ups since they have beaten these opponents before. However, both our heroes are in for a frightening surprise when World Three tricks Maylu into downloading a special BattleChip that transforms Roll into an evil NetNavi! The newly transformed ""Empress"" immediately launches a vicious attack against MegaMan. Will she succeed in finally deleting him?
Disguised as Higsby, Yahoot gives Maylu an evil BattleChip, which she uses in her team match with Lan--against Mr. Match and Maddy. This ""twisted chip"" has now taken over her PET and put Roll under the control of Count Zap and World Three! Every time Lan sends MegaMan into action, Roll, now calling herself Empress, steps in his path and attacks our blue hero! Finally the real Higsby appears and tells Maylu the secret to stopping Roll from her rage. With Roll back to normal, Lan and Maylu easily win the match. Up next, Chaud and ProtoMan are teamed up with a teen NetBattler and his singing NetNavi, ShiningMan--against WhaleMan and RocketMan. Not exactly team players, Chaud and ProtoMan take out their opponents and ShiningMan in one blow!
This episode only aired in Canada. In the US, this two-part episode was compressed into one episode.
PharaohMan has returned, and he's back with a vengeance! Mr. Wily sends an army of StoneMan and BlasterMan clones to capture the NetNavi, but PharaohMan has plans of his own. Meanwhile, Lan gets a shock: Chaud actually feels bad about MegaMan being deleted and offers to help him! But maybe MegaMan isn't gone after all, since Lan and his friends find strange data on their PET's. While they try to figure out how to rebuild MegaMan, PharaohMan, angry because he was imprisoned for twenty years and had his ""kingdom"" taken from him, uses the Cyber Network to cause disasters in the real world. And then, Lan's father shows up to help Lan and his friends--surely he can bring MegaMan back.
Lan, Maylu and Chisao visit the Sci-Labs and witness Dr. Hikari's latest experiment in Dimensional Area technology—CrossFusion, the merger of a NetOp with his/her NetNavi, but the CrossFusion makes a NetOp lose his strength. However, the laboratory is attacked by real-world viruses and the Darkloid NetNavi SavageMan. Lan has no choice but to perform CrossFusion himself and stop SavageMan. After beating SavageMan, Lan suddenly passes out.
After Lan finally wakes up, Yuichiro explains the SynchroChip to Lan, the chip that allows CrossFusion. Lan accidentally takes it with him to a museum exhibition on NetCity. A strange UFO appears over NetCity and begins sucking up NetNavis, so MegaMan and Roll jack-in to find SavageMan is responsible. Lan becomes an official NetSaver in this episode.
Lan visits the water works factory on a field trip when BubbleMan, a Darkloid NetNavi, attacks. He plans to flood every toilet in DenTech City. Lan uses CrossFusion to thwart him, but because he and MegaMan are bickering, the fusion becomes unstable. Lan and MegaMan stop arguing and work together to defeat BubbleMan.
When Lan is hired to find out what is causing the city's lights to burn out and destroy themselves, Maylu discovers Lan is a NetSaver. Lan finds himself battling with Darkloid FlashMan only to be interrupted by Maylu, who wishes to help. MegaMan becomes damaged with Roll's clumsy battling style, and Dr. Hikari has to repair him. However, FlashMan strikes again, so Maylu rushes off to defeat FlashMan and amend her mistake. In the end, FlashMan is defeated when MegaMan and Roll fuse their souls together and create RollSoul.
Ms. Mari and Tory take Lan and co. out on a hot springs vacation, but their strict rules make it difficult to relax. Lan also meets Tamako, a gift-shop owner who has a love for NetBattling. She challenges Lan to battle with her NetNavi HeavyMetalMan, but BubbleMan constantly interrupts, seeking revenge on MegaMan.
Higsby is desperate to impress Ms. Mari, so he takes her out to go virtual bowling. Lan and Maylu tag along. Meanwhile, bowling expert BowlMan becomes infected with a DarkChip and plans to destroy the bowling alley. Lan CrossFuses to fight back.
Lan investigates a science museum being built when the NetSavers receive word of a possible Darkloid attack. However, it was a set-up by SavageMan. Duplicating Lan's frequency, MegaMan is confronted with an artificial Lan, disabling cooperation with his NetOp.
