In 2071, roughly fifty years after an accident with a hyperspace gateway made the Earth almost uninhabitable, humanity has colonized most of the rocky planets and moons of the Solar System.

A group of young pirates come from space to Earth to obtain the "Greatest Treasure in the Universe", which can only be acquired after obtaining the Ultimate Powers of the different 34 Super Sentai Teams. However, they end up running afoul of the Space Empire Zangyack, whose earlier invasion forces were wiped out by the 34 Sentai groups long ago. As a result, the space pirates use "pirate copies" of the powers of the older teams and fight the Zangyack forces as the Gokaigers.
