Springfield High School student Dawn Moreno caught the attention of Cobra Commander after successfully beating the entire lacrosse team by herself. Quickly proving herself invaluable, he made her his apprentice. Under the tutelage of Baroness, Dawn was strapped into the Brainwave Scanner and mistakenly implanted with the stored memories of Snake Eyes. A highly conditioned and athletic teenager now possessed the knowledge of an Arashikage Ninja and seasoned combat veteran. Confused by the flurry of new memories, she ultimately found guidance from Storm Shadow and his aunt Obake Obaasan who completed her ninja training in Tokyo. Eventually Dawn learned to achieve peace between her own psyche and that of Snake Eyes, embracing her new calling as a member of the Joe team. "Rescued as a teen from a bleak life in Cobra. Honed into a ninja master. Inherited Snake Eye's memories via Brainwave Scanner. Stealthy. Speedy. Deadly. You'd better believe Dawn's a Joe."
