ReBoot

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.

The joy of receiving a new upgrade is cut short when it turns out to contain Megabyte himself, who's decided to take a more direct approach to infecting the core.

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.

The citizens of Mainframe start to battle the supervirus Daemon who has infected 92% of the Net. Bob is horrified to discover that she has infected all the other guardians.
