Bionational was a large company that was active in the Early 2190's. Much like the Weyland-Yutani Corporation, Bionational wanted to get it's hands on a Xenomorph specimen and capitalize off using the creature as a bio weapon.
Getting a Xenomorph on Earth
The company got its wish to acquire a Xenomorph specimen in early 2192 when one of its employees, Jim Likowaski, was impregnated by one of the creatures. They kept Jim at their Huston Labs to study the effects on the host, and after the Xenomorph left its host it attacked the Project Leader with the assistant shooting and killing the scientist. The Xenomorph stayed in the dead scientist's body and eventually molted into a Queen; after which the company moved her to their Lima Facility. The facility was later attacked by a group of cultists lead by a man named Salvaje, who was a former employee for Bionational. Several impregnated cultist managed to escape the base's self-destruct, starting the Xenomorph infestation of Earth.
Competition with the Terran Government
Bionational found out about an expedition set up by a Government Agent named Orona. The company didn't want the government to interfere in the private sector of weapons manufacturing and set out to sabotage the mission. Two of the company's executives, Red and Green, sent out one of their "Executive Assistants of Security", Massey, to deal with the mission. The company also managed to get USCM Colonel H.S. Stephens on their payroll and to assist Massey in sabotaging the mission. Ultimately, Massey killed Stephens and sent most of the Marines and crew to the surface as food for the Xenomorphs before he himself was killed by a stowaway. The surviving Marines and crew ultimately failed in their mission.
