The Annihilator is a sophisticated antimatter weapon designed by John Henry Irons. Back when John Henry worked for Amertek Industries, created many powerful and dangerous devices. The most powerful of those devices was the Annihilator. When John realized that his weapons were being used to harm the innocent, he quit his job and destroyed his designs. However, when he created this weapon, he told no one about its existence, not even his friends at Amertek. Knowing the Annihilator was too powerful for anyone to wield but knowing that such power might be needed one day, he hid it instead of destroying it. As an added precaution, he removed the computer chip needed for it to work in case anyone were to find his hiding place. He left it buried there hoping he would never have to use it.
However, when his battle with the group Black Ops escalated, John decided he needed his old weapon to help him defeat them for good. After Black Ops kidnapped his niece Natasha to try to get him to surrender, he decided to put the Annihilator into action. When the fight reaches its climax, Steel accidentally kills three young Black Ops members when his aim is thrown off. Guilty over the three dead (later revealed to have survived) and worried that the Annihilator would find it way into the wrong hands, Steel activates the self-destruct mechanism after the fight ends, disintegrating it.
