Ruby Rose: Blackwatch Agent

After Summer's death, Taiyang blamed Ruby. Yang wanted to protect her cause she didn't want to lose her sister and her mom. But Ruby wanted to be a huntress, and managed to convince Qrow to train her behind everyone's back. However, when Weiss tells Ruby that she doesn't deserve to be in Beacon, Ruby snaps. She yells out her life story at Weiss, and then leaves, vowing to return with the heads of Roman Torchwick and Cinder Fall as proof of her abilities.

But that didn't happen. Ruby got caught in a worm-hole, and got dropped in the middle of the omnic crisis. Quickly adapting to survive, the people of New York told legends of the red blur that slew omnics in a matter of seconds. Overwatch quickly took notice, and recruited her during the days shortly after their formation. Now, Ruby is a member of Blackwatch as their sniper. Let's see how things change.
