The X-Files

Knowle Rohrer
Adam Baldwin, who played the super soldier Knowle Rohrer.

Knowle Rohrer is portrayed by Adam Baldwin. He served alongside Sergeant John Doggett in the U.S. Marine Corps with the 24th MAU (Marine Amphibious Unit) in Beirut, Lebanon. Doggett and Rohrer were friends, but lost touch when Rohrer and Shannon McMahon were taken out of their company to be the first people transformed into Super Soldiers, a new type of alien-human hybrid intended by the alien Colonists as replacements for normal humans.[63]

Knowle continued on with his military career by joining the Department of Defense. The work he did there is unknown, but it is safe to assume that he was involved in classified operations. When Doggett became assigned to the X-Files, he re-established contact with Rohrer.[63][64] Doggett became suspicious of Rohrer when information was given to him from Rohrer that got a man killed, but it was not until Doggett saw Rohrer meet with Alex Krycek that he realized Rohrer was a member of the conspiracy.[19]

In "Nothing Important Happened Today II", he is decapitated by fellow Super Soldier, Shannon McMahon, but owing to his hybrid abilities, manages to then impale her with his arm, and they both fall into a water reservoir, presumably both now dead.[20]

However in the series finale, "The Truth", it is revealed that he survived, when Mulder breaks into Mount Weather. Rohrer chases down Mulder, and in the ensuing scuffle, Rohrer plummets onto some power lines. Mulder is then taken into military custody and put on trial for Rohrer's supposed death. Eventually, Mulder breaks out with the help of Alvin Kersh, and with Dana Scully, headed to New Mexico for a final confrontation with the Cigarette Smoking Man, whom he discovered was still alive. Doggett and Monica Reyes went after Mulder and Scully to warn them that the conspirators knew where they were. Rohrer, alive and well, followed, intending to kill them all (including the Cigarette Smoking Man, who had long since outlived his usefulness to the conspiracy). However, as he approached Doggett and Reyes in the New Mexican desert, Rohrer died from exposure to magnetite. It turned out that the Cigarette Smoking Man figured out that magnetite killed the Super Soldiers, and consequently chose to hide in a pueblo saturated with it.[28]
