Aurora Star
Aurora Star is the entity formed upon the merging of Claire O'Carrol, a fashionista and aspiring model, with "Aurora," a notably old Kheldian who has been hosted by several heroes throughout history. Claire received the Kheldian from her predecessor, Aurora Flare, who had been so critically wounded even the considerable healing powers of a Peacebringer could not save him. Claire, who happened to be shopping when the skies above her erupted in superpowered battle, agreed to be a temporary host to Aurora until a more permanent host could be found. However, as the battle raged on both Claire and Aurora found common cause in their desire to help, and once each realized they had a kindred spirit in the other, their minds joined, instantly creating a new superhero.
Aurora Star has always assured interviewers that she retains Claire's personality and memories, brushing aside any concerns for her human side with a single line, "I wouldn't change a thing."
