The Afghani

A former U.S. Marine Raider living in a city corrupted by gangs and mobs decides to take up the superhero style-moniker "Gladiator" while he cracks criminal skulls- but no one will actually call him that. While engaging in these activities, Silas Roman meets strange new people (kills some, befriends others), gets into dangerous firefights and makes crude remarks about everyone around him while at all times maintaining a sulky, depressed demeanor, while he hides his traumatizing past from his allies.
