Minami Matsunaka

The Space Empire Zangyack forms an alliance with the Black Cross King, the resurrected form of the Gorengers' enemy the Black Cross Führer, in order to invade Earth with other revived Super Sentai enemies. The Gokaigers, along with the Goseigers, who have lost their powers from the Legend War, must team up in order to fight against the new enemy.

First volume in the 2 Channel series.

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.
