Fremmlins were the dominant species of the United 'Gees Galaxy for about three centuries. From the Fremmlin Dress Code Law, passed a few months after Fortran took over, made all of the male Fremmlins dress similar to Fortran. Females were supposed to dress like Ulona, but the law was ended after she disappeared. The Fremmlins nearly went extinct after a teenage Weegee was struggling to get control over his newly obtained Weegee Virus, accidentally turning most of the Fremmlin population into disfigured teenage Weegee Clones. (There are still a few left.) Weegee's former best friend, Sammy (now Skelemar) was also a Fremmlin before his mutation. Their homeworld was Fremm.
- Fremmlins begin to grow moustaches at only 5 years old. (This was due to a genetic mutation)
- Every Fremmlin has blue eyes.
- Fremmlins were the enemies of the Fremmoids.
