Instead, a parallel title, "Legionnaires," was launched, starring the "SW6" Legion, whose origins were not resolved until the "" crossover by a different writing team. "Legionnaires" was lighter in tone than the main Legion book, and was written by the Bierbaums and drawn by Chris Sprouse. Giffen left the book after a storyline which involved the destruction of Earth, and the Bierbaums continued writing, overseeing the return of several classic characters. When the Bierbaums left, writer Tom McCraw took over and made a number of changes, such as forcing several Legion members underground, which required them to take on new identities and costumes, and bringing back long-absent Legionnaire Wildfire.
