However, they end up facing the Space Empire Zangyack, whose eariler invasion forces were wiped out by the 34 Sentai groups long ago before a new invasion force is established under Commandant Oiles Gil, the emperor's son. As a result, due to their history with the empire, the space pirates use the powers of the older teams to fight the Zangyack forces as the Gokaigers.
