After watching the Gokai Galleon crew for over a week, Ninjaman decides to train the pirates in the basics of being a Super Sentai team. With only Doc, Ahim, and Gai going through with it, Ninjaman deems only them worthy of the Kakurangers' Great Power before sensing a strange presence. He and the others discover Action Commander Juju as he summons two Zugormin to fight them before Gokai Red, Gokai Blue, and Gokai Yellow arrive. After firing darts into Gokai Green and Gokai Silver, Juju is forced to retreat after failing to hit Gokai Red. Soon after, while having lunch, Doc and Gai suddenly start acting crazy and they go out to fight. Ahim follows them as Ninjaman follows in a huff after seeing Captain Marvelous and the others show no concern. Ahim and Ninjaman find many other people acting crazy before finding Doc and Gai fighting each other before assuming their Gokaiger forms as they attempt to stop them. But in a gambit, Ahim ends up taking the two's blows as she manages to snap Gokai Green and Gokai Silver out of their madness. By that time, having Navi analyze his Gokai Saber for Juju's mind-altering dart, Gokai Red and the others find the Action Commander's base and they attempt to destroy the crystal ball he is using to control people. However, Juju swallows the crystal ball to ensure that his spell over the humans continues. Contacted by Navi, the others arrive to their shipmates' aid against Juju as they use the Sun Vulcan Keys to defeat some of the Gormin. After apologizing for underestimating them, Ninjaman joins the Gokaigers as they use the Kakuranger Keys to fight Juju and the Gormin while Gokai Silver assumes Gold Mode to defeat the Zugormin. After being hit by the Gokai Galleon Buster, ensuring his spell is broken, Insarn enlarges Juju as Gokaioh and Goujyujin are formed to fight him. However, Juju overpowers them before the Kakuranger Keys emerge as Ninjaman tells them to use his team's Great Power: which turns out to be himself. Ninjaman battles Juju before Kanzen Gokaioh is formed to deliver the final blow. Later, after deciding to find the Three God Generals, Ninjaman summons his cloud to take his leave until the Gokaigers need him once more. Knowing that they need the five Great Powers in his possession, the Gokai Galleon crew know that they must fight Basco to achieve their goal to get the Greatest Treasure in the Universe.
