of this alternate Earth, the tyrannical female Sphinx. He is shown the truth of how the female Sphinx used the energy of the Ka Stone to reshape reality by the original Sphinx's former advisor, Sayge. Nova betrays the Sphinx to join Marvel Man (Vance Astrovik) and Firestar of that world's Mutant Liberation Front as well as Night Thrasher, whose parents were murdered in this reality on the orders of the Sphinx. When Nova threatens to murder the Sphinx's cat, she restores reality. Nova 0:0 The second Nova series Nova deals with Nova 0:0, who is much more adept at using his powers than Richard Rider. He often fights Nova to test him and to push Nova into using his powers in new ways. It is revealed that this Nova is, in fact, the alternate reality version of Richard's younger brother Robert. In that reality, Robert gained the Nova Force powers instead of Richard and stayed behind to lead the Nova Corps and help Xandar rebuild after the war with the Skrulls. Robert's Earth had been destroyed by the Deathstorm while he was off in space. Nova 0:0 would later sacrifice his life preventing the Deathstorm from destroying the 616-version of Earth. He died and was buried on Mars. In the fourth volume of Nova, the Robert Rider of the 616-version of Earth also becomes a member of the Nova Corps (alongside various other humans and non-humans) and again proves capable of using his powers in ways his brother Richard had not. What If Issue #15 of What If? contained four stories in which a young widow, a homeless man, Peter Parker, and a criminal became Nova instead of Richard. In What If? Annihilation, the Annihilation Wave reaches Earth in the climactic battle of the super hero Civil War. Nova, Captain America, and Iron Man work together and sacrifice themselves while using a weapon to destroy the Wave and save Earth.
