Dr. Marbles builds Symmetria because of his passion of symmetry, but Hacker steals the symmetrizer and destroys Symmetria by splitting everything symmetrical in half. The Cybersquad has to figure out how to get the symmetrizer back from Hacker.

The Cybrary, owned and operated by Ms. Fileshare, has a bug problem, so she hires an exterminator named the Vermin Vexor (Hacker in disguise) to help her with the problem. Hacker instead adds more bugs so all references of Motherboard get switched to himself, and he alters two bar graphs to hide the truth.

The Cybrary is under attack again, and the kids have to use logic and elimination processes to stop Hacker from entering Motherboard's vault.
