Transigen

Featured in: Logan (2017)

Secretly, Transigen and his partner Alkali were putting chemicals in mass-produced foods, such as genetically modified corn stalks. These chemicals were suppressing the mutant X gene from being produced and therefore were responsible for the lack of mutant births in the future. Dr. Zander Rice wanted to do this so that mutant births could be selective and controlled.

Transigen began to breed mutants to be used as weapons. They used randomly selected young women to take the child and used genetic samples of mutants to impregnate them. The children were raised in the Alkali facility, where they were subjected to brutal treatment to try to be subjected to obedient weapons for Transigen.
