In the rain, Joe wakes up his shipmates as they gather around the wounded Captain Marvelous, apologizing to them for both their Ranger Keys and the Gokai Galleon being taken by Basco. Taking Captain Marvelous to an abandoned church, the crew learns that Captain Marvelous never learned what the Greatest Treasure in the Universe is or cared what it is so long as it was something no pirate has ever obtained before. Luka gets a call from Navi who has been hiding in the bridge, giving them the location of the Gokai Galleon. Learning that Basco has placed the ship on lockdown, the crew assure their captain that they will take back the Gokai Galleon. Once inside, the pirates burst into one of the lower decks and split up to find Navi. However, the two groups end up facing their respective Ranger Keys which Basco animated to also track down the bird. They manage to defeat the Ranger Keys, allowing the pirates assume their Gokaiger forms to find Navi just as he is brought to Basco so he can proceed to use him. Admitting how impressed he is with their meddling, Basco sends the Gokaigers outside as he has the Gokai Red Key fight them. Upon defeating the Gokai Red Key with the powers of five red Sentai heroes, the Gokaigers use the Gokai Galleon Buster on Basco before he deflects the blast back at them and takes their Ranger Keys, again. Before he can kill them, despite his injuries, Captain Marvelous arrives to finish things with Basco. Though Basco tries to waver his resolve by revealing that Aka Red is from Earth and was gathering the Ranger Keys just to bring them to his home world to protect it, he sees Captain Marvelous will not budge from his dream nonetheless and accepts the challenge, acknowledging him as Captain Marvelous. They have a fierce battle until Gokai Red stabs their feet together to hold Basco still as the two exchange one final blow before being knocked out, but Basco realizes his shot was blocked by a piece of the bomb he put in Sally while he suffers a fatal wound and perishes soon after. Captain Marvelous reclaims his crew's Ranger Keys before collapsing out of exhaustion. Though the others are concerned, their captain points out that they have the all of the Great Powers and can finally begin their search for the Greatest Treasure in the Universe.
