Biography
Similar to his canon counterpart, Gordon is a theoretical physicist employed at the Black Mesa Research Facility. Following the resonance cascade which triggered the Black Mesa Incident and allowed aliens to come through from another dimension and start killing scientists in the facility, Gordon found his "calling" and became a serial killer. He took advantage of the chaos to start murdering any colleagues such as fellow scientists as well as security guards in brutal ways, but as long as they weren't of any use. As Gordon progressed through Black Mesa he detached from reality further and couldn't escape his darker side, and began to practice many ways to kill scientists and guards. He would also trap scared scientists in rooms with alien creatures and leave them to their grisly fate. Gordon had also managed to catch up the with the sinister suited individual known as "The G-Man", although G-Man would claim to be the facility's administrator and distracted Gordon from trying to harm him by claiming he would help him escape to the surface. During a second encounter G-Man grew sick of Gordon and dispatched a bullsquid to attack whilst G-Man escaped. Gordon managed to make it to the surface but was captured by the military. They had managed to monitor his sadistic acts of violence and torture by hacking into his Hazardous Environment Suit and knew Gordon was too dangerous to be kept alive, so threw him into a trash compactor. But Gordon managed to evade being crushed to death and escaped through a vent and into the outside world.

Gordon managed to escape the Black Mesa Research Facility before it was nuked, and wasn't disturbed by the G-Man. Gordon's activities following the invasion of the interdimensional alien empire is unknown, but a decade later he turned up in the Combine run city known as City 17, located in Eastern Europe. He got reacquainted with Alyx Vance, the daughter of a colleague known as Eli Vance, who then took him to his former boss Isaac Kleiner's lab. He later traveled to Nova Prospekt with Alyx to free a captured Eli, where he blew up the facility and escaped back to City 17 with Alyx and their companion The Turret. Fiendman led the resistance against the Combine, although secretly began wiping out squads that were helping him out. With his first squad he lured them to Combine mines and blew them up, and then imprisoned the last survivor in an abandoned apartment to leave him to die. When traveling underneath the City 17 tunnels he imprisoned another rebel group to be left at the mercy of the manhacks and a spilt radioactive waste.

Following Alyx's capture Fiendman gained access to the citadel to confront Combine leader Dr. Wallace Breen, his former Black Mesa administrator. Fiendman is captured and taken to Breen's office, where Breen offers Fiendman a chance a job offer. Despite Alyx and Eli's pleas not to listen to him (assuming Fiendman is actually Gordon Freeman), Fiendman accepts the offer and joins Wallace Breen as his Number 2. Eli is sent to the dark side of the Combine portal, and Alyx is forced to be Fiendman's slave in his private quarters in the citadel, where he begins plotting to bring down the entire resistance.
