After watching the Gokaigers defeat another wave of Zugormin with Go-on Gokaioh and Goujyujin, Warzu Giru throws his usual temper tantrum over the loss until Insarn tells him of the unexpected visit from two members of the Imperial Guard, the Dogormin. Meeting with the Dogormin, Warzu learns that they have brought with them the Great Warzu robot, the Zangyack Empire's greatest war machine, for him to get the invasion back on track. Gokaioh and Goujyujin are formed to face the Great Warzu, which knocks Machalcon back into Machine World before overpowering the Gokaigers' Goujyu Gokaioh formation. Sparked by his memories of Aka Red's death, Captain Marvelous refuses to let his crew die as he forcibly ejects them to safety.
