Epic 22: Over the Rainbow

Over the Rainbow is the twenty-second episode of Tensou Sentai Goseiger.

Plot
After accepting Makuin's offer to finish things with Groundion, Uobouzu of the Nessie starts attacking humans by going on a shadow-eating spree. When the Goseigers arrive, Gosei Knight recognizes the attacks to be Uobouzu's work as the Yuumajuu reveals himself. With the Goseigers unable to fight back, Gosei Knight tries to fight Uobouzu, but Uobouzu takes his leave when a cloud blocks the sunlight. Later, as Gosei Knight feels that the current Gosei Angels are weak compared to their predecessors, the Master Head describes to the others Groundion's fight with Uobouzu in the past, but this is cut short as Datas reveals that they need to destroy the Yuumajuu to save his victims. The next day, Uobouzu resumes his attack before the Goseigers intervene and attempt to use their Tensou Techniques to create a rain storm, preventing Uobouzu from eating any more shadows. Gosei Knight arrives as the plan fails and fights Uobouzu himself until the Goseigers come to his aid. Understanding that the Goseigers' intent to help him and using their shadows as bait to trap Uobouzu, Gosei Knight assumes his Headder form to rip the Yuumajuu's tongue off before using the Knight Dynamic attack to defeat Uobouzu. When Uobouzu is revived through the Bibi Bugs, the Goseigers form Gosei Great and Gosei Knight becomes Gosei Ground to fight the enlarged Uobouzu. The two formations are not strong enough to defeat the Yuumajuu and are broken up. While things look grim, the Goseigers and Gosei Knight decide to combine their Gosei Machines to form Ground Gosei Great. Together, they destroy Uobouzu before it starts raining. Soon after, Gosei Knight finally accepts the Gosei Angels but he feels they need a bit more training. He takes his leave, as a rainbow forms in the sky after the rain stops.
