Name - Ashton
Surname - Barton
Nickname - Ash
Description - A mutant, who can manipulate elements of all kinds. She has a short temper (fire) a cold personality (ice) more wise than she thinks (air) has a solid humor (earth) (more elements she can control, just isn't in her personality)
Background - Been on S.H.I.E.L.D's radar for a while, not as a villain but as a threat. (I guess Loki can live with the Avengers for a punishment, like you see in a lot of fanfics) and Loki takes interest as well.
(I will post a picture of what she looks like on my profile)
