One major storyline during this period was the discovery of Batch SW6, a group of clones of the early Legion (from their "Adventure Comics" days), created by the Dominators. Giffen's original conclusion for the storyline was that the clones would eventually have been revealed to be the real Legion, and the ones whose adventures had been chronicled since the 1950s were actually the clones. The adult Legion's secret programming would kick in, forcing them to fight the younger Legion and leading to a fight to the death in which Legionnaires on both teams would die, with the victims’ names being picked at random. Afterwards, the older team would explore the Vega System as a 30th-century version of the Omega Men in a new series while the younger team would act as the main Legion on Earth. Giffen's other conclusion was for several of the younger and older Legionnaires to die while liberating Earth from the Dominion. The older Legion would defend Earth while the younger Legion would act as the last line of defense for the United Planets as the Omega Men.
