The G-Man

The G-Man, also known by his human alias Frank Blackstone, was the central antagonist and anti-hero of City 17 and main protagonist of the spin-off Blackstone.

He was a fomer human that was employed by the mysterious "Employers" and granted special abilities such as reality warping and jumping between realities. He was tasked with gathering potential "Employees" to work for the Employers, with candidates being Gordon Freeman, Adrian Shephard, Alyx Vance and Nathan Johnson. He was also involved in the Xenian invasion of earth, which then led to the Combine seizing earth and enslaving the human population.

Following the downfall of the Combine, G-Man attempted to wield control of earth for himself and used Nathan as a puppet. This led to G-Man's downfall, and he had to live under the radar as a human civilian. After a near death experience at the hands of his business partner Richard Woods, G-Man went on the run and took on the alias of Frank Blackstone. He began a life of crime and planned to use his illegally acquired money to fun his own crime syndicate. Following Nathan's presumed death, Frank attempted to settle down with Chell Johnson and began shady business dealings.

Frank attempted to find redemption, but found himself always returning to his old ways. He killed the Spider-Queen in August 2021, and planned to flee City 17 with stolen money. He was killed by Dan Mason and Billy Johnson, and his body dumped in a swamp. He was later resurrected by Walter and Maxwell Bennett and forced to become a slave. He became an informant to the Renegade.
