Gene was one of the Mendat Laboratories scientists studying the aliens on Antarctica. He was infected by them at one point and slowly began morphing. He began to exhibit growths and tenctacles like the aliens. When Blurr arrived at the facility, Gene was barly able to stand and his mind had been mostly taken from him.
Using some of the notes Beltran received from Captain Darkought’s ship and Blurr got from the facility, they were able to help Gene. The dissolving was halted, and he was restored to most of his former self. His mental functions recovered, and a cure to prevent this from happening to others was created. Gene still has an alien appearance to him now, but definitely has a humanoid form.
