Megabyte and Hexadecimal are about to take the core, but Mainframe is saved at the last minute by an incoming game cube. However with Bob gone, Enzo is left having the answer the call of the guardian protocol.

Megabyte is trying to turn Mainfraime against Enzo, blocking him from entering the games and smearing his reputation with propaganda. When the young guardian finally manages to sneak past the blockade, it's more crucial than ever that he wins, this time facing Rocky the Rabid Raccoon...

As Megabyte prepares to launch a another attack using the newly recovered Hexadecimal, Mouse initiates a project to seal Megabyte's domain inside a firewall. Enzo and AndrAIa face the user in a Toy Story-esque racing game.

Enzo and AndrAIa are caught in a tournament style fighting game where they have no control and may not be able to defend against the user.

After getting stuck in a game, Matrix, the hardened and cynical warrior once known as Enzo, and AndrAIa have been wandering the net for a very long time, moving from system to system through the games, searching for a way back to Mainframe. This time they arrive in a barely functioning system, devastated by virals and constant lost games.

Matrix and AndrAIa find themselves on different sides of a conflict between the mysterious Spectrols and a team of super hero sprites.

Matrix is shocked when he finds Mainframe inside a game cube. Dot is there... Phong is there... even Bob! But why did he and AndrAIa reboot as Megabyte and Hexadecimal? And who is Number One?

Having finally found a system with ports to the Net, Matrix is overjoyed. But it doesn't last long, when access is blocked as the city comes under siege by a team of... guardians?

Matrix and Andraia meet up with Captain Capacitor who promises to help them find Bob as long as they release his crew from the prison in which the guardians have placed them.

The crew of the Saucy Mare enter the web looking for Bob but when a web creature sucks away half of AndrAIa's energy, leaving her in a dying state, Matrix must find the creature so he can save her life.

The Saucy Mare is attacked by a group of degraded sprites riding web creatures, and AndrAia is saved by an old friend.

The traps Mouse once placed to stop the web creatures from accessing Mainframe are now making it difficult for the sprites to return home.

Matrix and the gang finally return to Mainframe only to discover it has been almost destroyed by Megabyte. We learn what the resistance has been doing all this time and the plan to finally save their home.

The battle for Mainframe begins and Matrix has a final confrontation with Megabyte. Meanwhile, Hexadecimal seems to have gone even more insane but Bob thinks he might be able to help her.

Mainframe begins to crash around them and users from games played break out into mainframe. Matrix meets up with an enemy from his past.

Mainframe is all but destroyed and Bob realises that their only hope lies in the user.

An accident causes a magnet to drain Dot of energy and, according to Phong, the only way to save her is to feed her slow food from Al's on level 31. While in Al's, the sprites are caught in a medival fantasy game where Bob and the user are attempting to reach Dot, the damsel in distress. Or are they?

Megabyte tries to blackmail Bob into stabilizing a tear into a portal to the super computer. As Bob makes an escape with the help from Dot the user inserts a game which stabilizes the tear. Bob and the rest of the sprites must race Megabyte, who has infected the user, to the portal to win the game and keep him from gaining access to the super computer.

Megabyte takes advantage of Enzo's new delivery service to try to deliver a delete command to Hexadecimal. Bob unknowingly attempts to deliver the package, only to be trapped in a racing game where the user's vehicle becomes a ticking time-bomb.

After Bob makes Dot late for an appointment, she and Bob get into a big argument. Seems Dot suddenly thinks Bob is too "random", and Bob thinks Dot is too straight-laced. Enzo and the other citizens of Mainframe try to trick the two into making up, but nothing seems to work. When Bob and Dot get trapped in a game cube, will that be enough of a crisis to get them to stop squabbling?

Megabyte steals Hexadecimal's precious Medusa Bug but finds it to be a trap which turns everything in Mainframe to stone.

Mike the TV is driving everybody insane, but when a game cube drops and Mike reboots into a warrior they're going to need him to help stop the user.

Dot is arranging a celebration for Enzo's first birthday, and Bob has to keep the young sprite occupied until everything is ready.

Mainframe is thrown into utter chaos when Hexadecimal manages to tap into the system's paint function.

Two special agents from the CGI are investigating disappearances in level 31. Their prime suspect is Mouse but the real abductor ends up being something far more dangerous: a web creature. The Guardians would destroy all of Mainframe to kill the web creature, but Bob has other ideas.
