Runaway ->> Avengers

Adabella Hawthorne is a 16 year old girl terrified for her life. She is special.
She has a very high metabolism (she's really fast), she has telekinesis (she's really weird), she's very strong, and she has great aim.
She has the making of a future Avenger, but she doesn't want to be one.
That is, until she realizes she is in danger. She has the potential to be a weapon.
And then, she meets Loki.
