In the pilot episode "Lost My Marbles", Hacker infects Motherboard with a computer virus. At a library on Earth, while looking at a computer, Jackie, Matt, and Inez (who accidentally let Hacker unleash the virus by touching the computer map simultaneously) are sucked through an interdimensional portal into Cyberspace. In their first adventure, they go to an island to rescue Dr. Marbles. In subsequent adventures, they return to Cyberspace to thwart Hacker's evil plans, ranging from ruining Motherboard to trying to take over a Cybersite. Throughout the season, the Cybersquad searched for a new encryptor chip for Motherboard. In Episode 9, Buzz and Delete nearly retrieved the encryptor chip, but lost it in a dust storm, much to Hacker's frustration.
