Hacker, other villains

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. Inez suspects that the virus is also what causes Motherboard to talk in riddles[5], which sometimes causes confusion when she instructs the CyberSquad.

Physical appearance

Motherboard is a 3D-animated periwinkle head and neck that is almost always seen through a computer screen. 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 vertical 3D text reading "M57383", which may be a serial number. Motherboard's left eye is a yellow sphere, and her right eye is an orange rectangle; her irises are blue. Her nose is an oblique quadrilateral pyramid. She has dark red lips.

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]

"The Poddleville Case" (pilot)

Motherboard in the pilot.PNG

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] This design was replaced by the final series premiere.

Season 1

Motherboard in Season 1

In Season 1, Motherboard faces forward and rarely, if ever, rotates. However, she appears to use the same 3D model as in later seasons. For instance, when her left eye jumps away from her face in "Cool It", it seems to change perspective and foreshorten consistently.

Motherboard is sometimes depicted with a drop shadow against her background.

Seasons 2–5

From Season 2 onwards, Motherboard often turns her head and is viewed from other angles, making it apparent that she is 3D modeled.

Seasons 6–

Motherboard's appearance was updated in Season 6. Some of her edges appear rounder, and she is lit more brightly. Her full model is much more often animated with squash and stretch.

Hackerspace fantasy sequence

Untitled 489092.jpg

In the scene of "The Cyberchase Movie" where Hacker imagines reformatting Cyberspace, Motherboard has the color palette of Hacker's body, with green skin and black hair. The colors of her background are green and purple. Finally, her eyes glow green. Her lips appear unchanged.


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 is also equipped with memory shields, which seem to prevent her from breaking down[14].

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].

Motherboard can generate or summon certain objects, such as the Skwak Pads[1] and snow clothes[15].


Main article: Virus

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. 

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"[16].
