When the Imperiex fleet attacks Earth, Strange Visitor gives all of her powers to Superman to give him the necessary power boost to defeat Imperiex. He defeats the powerful entity by cracking his armour and draining his energy, an act which ended her life (although she noted that 'Sharon Vance' had died when she was created and what was left to form Strange Visitor was just the essence of Sharon giving her a personality), while opening the way for Superman to vanquish Imperiex and save the universe.
