Kevin Keene and his dog Duke have been transported to Video Land and asked to help defeat Mother Brain.

Across the vastness of Videoland, on the magical world of Hyrule, years have past since the fall of the evil wizard Gannon, and peace reigned throughout the land. Until one dark day, rumor spread that the evil Gannon would rise again. That becomes true. Kevin and the N Team head to Hyrule to meet Kevin's favorite game hero Link and Princess Zelda. Mother Brain gives the Potion of Power to Gannon that restores the evil wizard to his rightful form. Mother Brain tries to get Gannon to serve her, but he refuses and sends Mother Brain, Eggplant Wizard, and King Hippo through the ceiling. Can the N Team and Link stop Gannon and his minions?

Dr. Wily goes to Kongoland to extract sap from trees. He uses it to make special hypnotic ink. Whoever read anything printed with the ink would be turned into a zombie whenever the words ""MOTHER BRAIN IS YOUR MASTER"" appeared in the text, and would have to obey Mother Brain's every command. Dr. Wily began taking over everyone on News World. A week later, the Paperboy, Julio, summons the N-Team to investigate. At first they're skeptical, but when Julio's mom gets turned into a zombie and tries to kill Kevin, they believe the story. Mother Brain finds out the hypnotic ink will also let her control machines. The N-Team finds King Hippo and the Eggplant Wizard at the Daily Sun. Kid Icarus shoots them with love arrows, and the two servants spill the beans on Mother Brain's plan: to take over VideoLand using the ink. Eggy also tells them the antidote: the sap of another tree on Kongoland. It turns out Julio hasn't turned into a zombie because he can't read. He's been skipping school to earn

The N-Team is playing a shooting game, while Mother Brain, King Hippo, and Eggplant Wizard watch on Metroid. The game ends, and they're about to go back to the Palace, when the Warp Wagon is pulled down to the world of Tetris by a powerful force. Mother Brain sends Hippo and Eggy to Tetris to find the source of that power, so she can get it for herself. It turns out that on Tetris, everything is square- and cubed-shaped. The N-Team is greeted by Mayor Squaresly, who declares today ""Her Royal Roundness Day"". The people of Tetris love holidays! The mayor takes the N-Team to CUBIES, ""home of the best square meal in town"", where they meet Lyle, Lana's clumsy older brother. The two siblings hadn't seen each other for two years. Lyle's been on Tetris all this time, and doesn't even know that his father is missing. He's a Keeper of the Sacred Square (the powerful force that pulled down the Warp Wagon). According to legend, the Square is so powerful that it built the entire world of Tetris. Ly

Dr. Wily creates an android that is a replica of Kevin's worst enemy from high school.

The N-Team is invited to Kongoland by Prince Plenty. Dr. Wily invents a brain swapper so Mother Brain can get a body. She chooses Princess Lana as the donor. However, when they go to Kongoland, Donkey Kong kidnaps Mother Brain and Game Boy. The brain swapper is accidentally attached and activated. Donkey Kong gets Game Boy's body, Game Boy gets Mother Brain's body, and Mother Brain get Donkey Kong's body. Simon and Kevin go to find ""Gape Boy"", Kid Icarus and Mega Man search for Game Boy's ""brain-in-a-bottle"", and Lana decides to give ""Mother Kong"" a makeover. Donkey Kong's family elect Simon their new leader! Everyone's brain is swapped back to the right place, and the Kong family carries Simon off.

Mother Brain makes a discovery that Kevin isn't very good at the Bayou Billy video game. So she sets a trap to lure him into Bayouland.

Kevin returns from Kongoland with a strange rock. Simon starts twirling it like a basketball, and it gives off a bright flash. Kevin ends up with blue strips on his face, and he swallowed his gum. Dr. Light is called to the Palace, and he says that Kevin has been bitten by a video virus. Kevin falls asleep, and inside Kevin's body, his life force does battle with Viroid. Because Kevin isn't from VideoLand, his body doesn't know how to fight off the video virus. Lana sends out a message to all of VideoLand begging people to contact her if they can help. Lana decides, from a statement made by Simon, to fight the virus from inside Kevin's body. Dr. Light gives Lana a map of Kevin's body and a videocom to contact him. Kid Icarus uses his special shrinking arrow to make Lana, Simon, Mega Man, and himself small enough. They enter Kevin's body through his right ear, but miss the shortest route to his heart, which is where Viroid has established his stronghold. They end up in the stomach, and

He's trying to get back to his own time. The thieves are using Kevin's weapons to power their time machine. Kevin eventually gets them back. He and Link return to Hyrule, leaving Pero to get back to his own time on his own.

King Charles is about to come home through a warp zone that only opens every 1000 video years. But he decides to send a supercomputer called Game Boy in his place. Game Boy turns out to be nothing but trouble for the N-Team. Mother Brain gets Game Boy, and Dr. Wily turns him into Game Brain. When the N Team comes to Metroid to rescue Game Boy, Game Brain sends monsters after them. Duke comes to the rescue, pulling the cords out of Game Boy with his teeth! The monsters disappear. Back at the Palace, the gang officially welcomes Game Boy to the N-Team.

The N-Team is on Baseball World, playing a game against Bo Jackson and the VideoLand All-Stars. Suddenly, Mother Brain opens a warp to the cellar of Baseball World, and all but Lana and Game Boy are sent through. In the cellar, the good guys can't agree which way to go to get out. They split up and go two different ways. At the Palace of Power, Mother Brain takes control and assigns Princess Lana to cleaning duty. Lana and Game Boy manage to get into the Communications room, and Lana contacts Kevin and the others in the cellar. She opens up a warp for them. After being in a confrontation with the Baseball Card King and evil baseball equipment, Kevin and the rest of the group go through a warp to the Palace. At the Palace, King Hippo and Eggplant Wizard present Mother Brain with a huge cake and a crown. A warp opens in the ceiling, and the good guys land on the cake. The cake moves to Mother Brain, King Hippo, and Eggplant Wizard and forces them up through the warp to the cellar of Base

At the Prince's castle, Kevin is bored of hearing the Prince talk of all his adventures. Astos comes to Kevin when he's alone and offers to help him gain popularity. He places Kevin under a spell and has him give the Prince a sleeping potion. Kevin and Astos then warp away to Astos' castle.

Dr. Wily has turned over a new leaf and is helping Dr. Light build a peace robot named Gamma?! It may sound bizzare, but really, Wily is faking this niceness! Mega Man, Kevin, Rush, and Duke are sent to eight other planets to collect eight energy tanks to power Gamma. All the while, Mega Man and Kevin argue about whose dog is awesomer. After getting all the tanks, they go to California Games for some rest and relaxation. But Dr. Wily warps the dogs to Skull Castle as bait for Kevin and Mega Man. Kevin and Mega Man go to Skull Castle to find their dogs. Leaving Doc Man (a robot from Mega Man 3 who can take on the powers of the Robot Masters from Mega Man 2) in charge of Skull Castle, Wily goes to Dr. Light's laboratory, reprograms Gamma, and steals it so he can take over VideoLand.

Kevin, Lana, and Duke meet Larry Bird. Hoopless, a young boy who is the inventor of everything on Hoopland, is too short to make a shot at getting a wish, so he has his robot, Rebound, make the shot for him. Rebound gets to make a wish, but, instead of wishing Hoopless tall, he accidentally wishes himself the tallest. He hits his head, which messes up his programming, and becomes evil. Larry, Kevin, Lana, Hoopless, and Duke climb Hoop Mountain, passing a series of challenges by Clockman, Guardian of the Magic Hoop, along the way. Lana wins a wish. However, instead of wishing her father back home, she wishes Rebound back to normal, and everybody's happy.

Kevin and Simon go to CastleVania to attend The Simon Belmont Awards, where Simon is going to be honored for being a hero like his great-grandfather, Trevor Belmont. The Poltergeist King appears on stage, where Simon expects to be presented with the weapons his ancestor made famous. Instead, the King calls Trevor a coward, and accuses him of stealing the credit after the King defeated Dracula. He curses the Belmont family with a thousand years of shame. He then disappears, taking the weapons with him. The audience begins booing Simon and throwing food at him. Simon escapes by running into a warp.
