Motherboard (sometimes "Mother-B") is the benevolent ruler and protector of all of Cyberspace. She exists as the brain[3][1] of Motherboard Control Central and watches over each cybersite[4]. Dr. Marbles and Digit are her technicians, as was Hacker prior to double-crossing her.

Motherboard is wise and powerful, but Hacker's virus has weakened her. She calls on Inez, Jackie, and Matt to help defeat villains such as Hacker and protect Cyberspace.[1] Her main role in Cyberchase is to give the CyberSquad missions and advice. Due to the virus, she is often interrupted by bursts of static and other malfunctions and seemingly has a propensity to talk in riddles[5].

Physical appearance

Motherboard is a 3D-animated blue head and neck with red lips. Her left eye is a yellow sphere, and her right eye is an orange rectangle; her irises are blue. She has wavy light blue hair and eyebrows with the texture of circuitry. Her nasolabial folds are also light blue, and her left one is 3D text reading "M57383", which may be a serial number.

When Motherboard is viewed from the side, her facial features are shown to be detached from her head by a significant distance, allowing the backs of her eyebrows, eyes, nose, and mouth to be seen. The geometry serving as her nasolabial folds is much closer to the front of her head than the other features, albeit also detached.[6][7]

In the original pilot demo for Cyberchase, an early version of "The Poddleville Case", Motherboard's design is much more abstract. She is two floating eyes with blue sclera and green irises, and a sine wave representing her mouth.[8]


Motherboard's components include the Encryptor Chip, the Memory Integrator which helps store her memory[9], and an unnamed panel that controls the portal system[10].

Motherboard has a coolant tank that stores cryoxide to prevent her from overheating[11], which can process other liquids such as antidotes[6]. She has a paper tape printer[12] and a laser printer that can shoot laser beams[11].

Hacker claims that a Digitizing Activator could scan a rod-based triangle to cure the virus. Although this turns out to be a lie, Motherboard did not dispute it, so the Digitizing Activator may be a real component that scans geometric figures or other objects for authentication or data encoding purposes.[13]

Motherboard's political philosophy involves a deep belief in a free and open cybersociety, which may be based on free and open-source software.[13]

Powers and abilities

Motherboard can generate portals to bridge physically distant locations in Cyberspace and the real world alike. Motherboard can even appear physically within the vortex, at a size that dwarfs the Grim Wreaker[7].


When Hacker removed Motherboard's Encryptor Chip, Digit put it back in, and Motherboard and Dr. Marbles rejected Hacker from Control Central. Despite the kickout, Hacker took Digit with him, and when they landed at the Northern Frontier, Hacker made him build a ship, along with Buzz and Delete. Then, Digit escaped to go back to Motherboard's side.

Shortly after his rebuild, Hacker launched a plan to get back at Motherboard. He programmed a library computer in the real world to crash, which would allow him to breach the system. He attacked while Motherboard was undergoing a upgrade. At that time, Jackie, Matt, and Inez were at the computer. After touching three dots, they crashed the computer, allowing Hacker to breach the system. Motherboard was able to warn the Doctor of the breach. Doctor Marbles attempted to reload the firewall (which had been off the entire upgrade), but the virus Hacker launched reached the computer before the entire firewall was loaded. Luckily, the firewall was up before the virus fully infected her, giving Motherboard only partial damage. 


Motherboard in Season 1

One effect of the virus that remains is that Motherboard sometimes flickers and squelches with static, which at times becomes so severe it cuts off her sentences.

Hacker describes the infected Motherboard as "but a mere fraction of her once-powerful self"[14].

The kind and caring ruler of Cyberspace. She keeps the virtual universe running smoothly and makes sure everyone is taken care of.

"CyberSquad" bio (2012)

Motherboard, the wise ruler of cyberspace, speaks from a computer at Control Central. Hacker has infected her operating system with a virus, so we often hear static as she tells the kids and Digit about important missions to stop Hacker. Signature line: “Hacker alert!”

Name origin

A motherboard is the main printed circuit board in a computer, which the other parts are connected to.


Marbles has created Symmetria, a harmonious cyberplace where everything is made symmetrical by a symmetrizer. Hacker steals the machine and reprograms it so that he can undo symmetry. The kids must master the properties of symmetry before Hacker destroys beauty, balance and harmony throughout all of cyberspace!



  • In Season 1, Motherboard faces forward and rarely (if ever) rotates, so she appears to be animated in a 2D style. From Season 2 onwards, she often turns her head and is sometimes viewed from other angles, making it apparent that she is 3D modeled.
    • Motherboard's model was updated in Season 6.
  • The DTMF signals heard when Jules tries to call Motherboard are 5-5-5, a common prefix used for fictitious telephone numbers.
