When the villainous variant of Reed Richards known as the Maker first brought about the creation of Earth-6160, it was clear that he had big things in mind for his new Ultimate Universe. Unsurprisingly, this world's heroes have done everything they can to bring about an end to the Maker's machinations. Despite how hard fought the battles leading up to the Maker's defeat were, the fact that he fell means that this world finally has a chance to develop the heroes it was always meant to have, and Tony Stark is leading the charge by creating a brand new breed of Ultimates.
