Hulk
When a monstrosity calling itself the Hulk came charging towards their base, Ross ordered an all out attack. It lasted nearly two hours because of the Hulk's might. he managed to grab Ross by the throat and say that he was Banner. Ross then realized that this was the greatest that ever happened to him, and the Hulk became his best weapon.

Red Hulk

He found a blood sample of the Hulk and injected it into himself. It began to have an affect on him straight away. He rapidly transformed into the Red Hulk and his mind became detached.
