The Roller girls were a gang in Fairfield, who were comprised of college-age girls who wore roller skates, had their faces painted to colorful geometric shapes, and were armed with antique Furon D-rays and dynamite when they attacked Big Willy's. The Roller girls were led by Mindy Peters.
When the 500th Big Willy's opened, the Roller girls attacked the restaurant and made off with the suitcase that contained the secret recipe. Orthopox then ordered Crypto to retrieve it, but, when he did so, the case turned out to be a decoy that contained a bomb, which disabled Crypto's Weapons, at which point he was forced to return to the Saucer, where he found four gang members guarding it. Pox was not happy about the attack, so he sent Crypto to find and destroy the gang's hideout. After that, Mindy decided to annihilate Big Willy's and ordered the Roller girls to plant dynamite on the restaurant, but failed. Pox then decided that it was was time to eliminate Mindy and told Crypto to find and Body Snatch The Corncob King, and meet Mindy in the park. Once they met in the park, Crypto jumped out of the Corncob King, and killed them both, using his Zap-O-Matic. Pox then decided that it was time to eliminate Fairfield and ordered Crypto to destroy every building, which destroyed the majority of the Roller girls. However, several members remained (thankfully), and attacked Crypto whenever he revisited Fairfield.
- D-ray: An old Furon weapon employed by the Roller girls.
- Dynamite: The Roller girls also used dynamite in their failed attempt to destroy Big Willy's.
