The CyberSquad is a collective term to refer to the characters that travel around to protect Cyberspace and Motherboard from harm's way, namely from Hacker and co. and they are protectors of Cyberspace.
The members of the CyberSquad are as follows:
Other members may include Slider, Creech, and Widget due to their connections and their status as recurring characters, though them not being constant characters makes them not be part of the main CyberSquad. Technically, anyone in Motherboard's alliance, especially if they are a kid helping in the adventures, is part of the CyberSquad, as revealed in "The Hacker's Challenge." However, only the four major members are constantly involved in the adventures and have Skwakpads, which mark their status.
