General Hayden

General Hayden is the human military commandant of the UAC space marine garrison in the Doom 3 novels (c. 2144-2145).

Background
He was a general in the space marines. He was in command of what was less than a U.S. government military unit than a Union Aerospace Corporation private security force.

Hayden had seen his share of battles— or “skirmishes,” as the United States government liked to call the never-ending little wars that plagued planet Earth.

Personality and traits
He was a man in uniform. Medals and colorful bars spoke of his experience; three stars indicated him a general.

Behind the scenes
In the 2016 reboot, Hayden has been reinterpreted as a scientist who came down with cancer and converted himself into cyborg going by the name Samuel Hayden, who is the chairman of the UAC and highest command on Mars.

Some particular differences include the fact taht General Hayden is human in the novels in 2145. Whereas Samuel Hayden was a cyborg by 6 months after Argent Tower was completed circa 2127. The only way for them to co-exist is if General Hayden was a decendent of Samuel Hayden.

General Hayden was merely a subordinate of Ian Kelliher, and his father Tommy Kelliher.
