The unnamed Combine Elite was under the employment of The G-Man during his temporary takeover of City 17 after the death of Wallace Breen. The Elite ended up being killed by Nathan Johnson who was on a mission to rescue Hannah Robertson.
The Combine Elite was a high ranking member of the Combine Empire during their control of earth. During the Uprising when Gordon Freeman infiltrated the citadel and got trapped in a stalker pod, the Elite took his superpowered gravity gun and presented it to his boss Wallace Breen. At Breen's orders the Elite left the gun on his desk and left him in his office to deal with Freeman.
In a new timeline where Breen was "killed" earlier, the Elite came under the employment of The G-Man and continued to work in the citadel. He was present when G-Man kidnapped Hannah Robertson and tasked Nathan Johnson to go on a long journey in order to rescue her, which Nathan accepted.
The Elite was killed when Nathan shot him dead and gained entrance to G-Man's office in the citadel in order to save Hannah.
- This character is supposed to be the same Combine Elite who took Gordon Freeman's gravity gun in the final Half-life 2 chapter "Dark Energy" and left it in Wallace Breen's office.
