Rookie and the Robber (Ashe X Male Reader)

This is about Y/N. At the age of 16 you lost your left hand to a Bastion unit and got it replaced with a robot hand. At 18 years old you became a gun for hire, rather you worked for overwatch, talon, drug dealers or the mob. It didnt matter, what did was the money. but that all changed after you turn 26. You were on mission with Talon, another assassination no big deal for you. But once the mission was over you were betrayed by known mercenary called Reaper. you got shot in the stomach and left for dead. Overwatch found you before you bled out and took you back to base. After healing from your wounds Overwatch wanted to hire you full time and you accepted. But what happens when you go on your first mission in months and you're up against the Deadlock Gang.
Note I dont own these characters or Art.
