That hot chick with the wings from X-Men.
From Create Your Own Story
I believe you're thinking of Angel Salvadore.
You add Angel in, making the others loyal to her. As her second-in-command, you add Lady Sif, who has more experience with leading and with old weaponry. And as the coordinater, you add Pepper Potts, with the Extremis stuff to make it more interesting.
Now, what do you do with this army?
Just watch and see what they do.
Oh, did I say army? I meant "group of hot chicks to stare at."
