Cold Boot, who answers to the nickname "Booty", is a spectral reformatted to be a sprite living in the Spectral System. Spectrals are not capable of rebooting, so when Game Cubes began entering the system a small group of spectrals volunteered to be reformatted into sprites so they could fight the Games. The new sprites called themselves the Hero Selective. Other members of the Hero Selective are Robert Cursor, Powerlock, Email, Feline, Pixel, Gigagirl, and Copy Girl. When they were not allowed to return to being Spectrals, the Heroes stopped fighting Games and let the Cubes damage the system.
Booty has a Scottish accent and can freeze things with a power blast.
When they started working together, they found that Powerlock and one of the Spectrals were actually viruses in disguise. They were planning to destroy the system, but the Spectrals and Hero Selective captured the Spectral Virus and questioned him. He started to scream how they would never stop his brother, but Pixel grabbed him and rendered him unconscious. They soon found out the other virus was Powerlock. They fought Powerlock in the Principal Office and deleted him.
- While he was only referred to as Booty on the show, the concept sketches show his full name to be Cold Boot, fitting his powers and being based on another term for a hard reboot.
- Cold Boot's personality is modeled after the Star Trek character Captain Montgomery Scott, also called Scotty.
- A cold reboot, also known as a hard reboot, is when power to a computer is cycled (turned off and then on) or a special reset signal to the processor is triggered. This restarts the computer without first performing any shut-down procedure.
- Cold Boot's physical appearance is a spoof of Marvel Comics character Iceman and Glacius from the Killer Instinct video game.
