(vigilante!tony stark au story.)
In some universes, there are lawful superheroes that prevent chaos and do their best to avoid causing it. In others, there are reckless vigilantes who kill when it isn't even necessary, thinking of themselves as heroes when, really, they should double-check their morals.
In this universe, vigilantes and heroes exist, but are awfully sparse. But one has made a name for himself - the "Iron Blade."
He isn't known for killing all that much, though he's brought death upon several large figures - bad ones, however. Nobody knows who's under the mask, behind the gun, holding the knife. Nobody knows but he himself.
Tony Stark.
Peter never grew up with Uncle Ben and Aunt May. He grew up with HYDRA, trained and brainwashed to be even better then the Winter Soldier.
He spends ten years with HYDRA, being their weapon. He's lost all hope that he would ever escape, but maybe a sliver of hope resurfaces when the Avengers are unknowingly sent to retrieve Peter.
Maybe Peter will be able to do something other then be a weapon.
•AU where Tony keeps his cool when he finds out the truth about his parents, and where they all stuck together.
