MHA sniper

A villain attacks, MHA headquarters everyone is fighting the villains that I have attacked. When all of a sudden they hear a loud gunshot coming from the roof of a building and immediately one of the villains is down bleeding. He is dead because you shot him. You are a 19-year-old female with purple hair that is long all the way down to your upper arm and a silky white dress. Normally, you are very sweet and no one has ever seen the side of you out of nowhere, you flip off a building with two hand guns at your side and you’re immediately shooting at all of the villains while still inside of the air, taking down all of them in one single swoop.
