Iron Cat, Vol. 1 #5A

Tony Stark's legacy is being set on fire by Sunset Bain. She's corrupted all of his armor and everything he's built since his very first weapon. And it's all Black Cat's fault. Now, Iron Man and Felicia Hardy (in her own Iron Cat armor) are fighting for their lives against the Hulkbuster armor and every other Iron Man armor in existence. This is not going to go well. Rated T+
