Suicide Squad/ Avengers- The Tainted Angel.

Casey Jones, She learned to use a gun after her flock left her. Yes i said Flock. She was the oldest at Itex or the school, being there since she was three, getting out at the age of 22, she is now 23 and was put in Belle Reves because it was found that she had extraordinary gunmanship and she 'destroyed' a lot of places, but that was running from Erasers. Of course no one knows that, or the fact she was experimented on since she was just a child and is now only 95% human and 5% bird. Meaning she has wings, Retractable ones, she can see really far away, she has hunters instinct (the guns), and she can here things if she concentrates on it, and the stronger bones, super strength and quicker healing that all the Avians get at 1% bird.
What will happen when she is put on the team that are sent to Stark Towers.

(Changing Killer croc's backstory btw he is not a metahuman he is a product of the school who escaped before his sister)
