y/n x avengers 640

You are Agent Silver, a highly skilled SHIELD agent and selective mute, i.e. you can talk, but choose not to as a response to your past, which no one except Director Fury, the head of SHIELD, and Agent Maria Hill, his second-in-command know. You joined SHIELD as its youngest member at the age of 16, joining as an active combat medic and undercover/espionage agent, quickly ascending through the ranks whilst being taken under the wing of Director Fury and Agent Hill, learning the trade from the best of the best whilst only being introduced to selective agents and politicians, remaining Fury's 'secret viper', as you heard yourself being nicknamed. Despite your lack of speech, you proved invaluable, able to perform tasks far beyond the average agent double your age, rivalling agents like Agent Barton, who was given the superhero name Hawkeye when he became a member of the Avengers, and Agent Romanoff, a professional assassin and spy turned SHIELD and also an Avenger, for your usefulness and versatility. But what will happen when you are introduced to the Avengers?
