Super Sentai - Season 45

The human world merges with the parallel world of Kikaitopia and the inhabitants of both worlds begin coexisting. But when the evil Tojitend dynasty begins their invasion, Kaito Goshikida obtains the powers of the Super Sentai across history to transform into ZenKaiser and joins forces with the Kikainoid Juran to fight back.

Mushrooms are everywhere. Suddenly, the world was flooded with mushrooms. Meanwhile, Kaito and Juran made their decision and in transforming they've grounded their opposition to Tojitendo's forces immediately. There are three Geartlingers left. In the plaza, a figure was captivated by Kaito's enthusiasm when it came to searching for more members to join his team as he was approached by none other than Kikainoid Gaon! Just as he forgets about the mushrooms, he drives his fangs into the Tojitendo. The fate of these cute and delicious mushrooms can't end like this.

Ah, this takes us back... The city has become all retro, and the Zenkaigers get a sudden blast from the past. Not to mention, is this where Yatsude makes her debut? Kaito's grandmother turns out to be extremely retro, as the others encounter a lonely boy who goes by "Ryo". It's said when two people meet in a retro world, the most retro adventure ever begins.

Hikoboshi World is attacking! But wait... what's that sound? A familiar "Yo-ho-ho!" can be heard faintly in the distance... And the voice of that same person gets powered-up! The shadow of the Yo-ho-ho Worldly Pirates is quickly approaching Saber and the gang! Suddenly, what will become of the destiny of these swordsmen...?!

Stacey uses Battle Caesar Robo II and an army of Sentai copies to overwhelm the Zenkaigers and their mecha, though Kaito has doubts regarding Stacey's conviction. After Juran calls out Stacey for hiding behind his mecha and Dark Sentai Gears, Stacey decides to face Kaito in a duel.

Finally, the day has come. The deployed Vacances World has succeeded in his invasion attempt. In a world that has been shaken by the trauma of the passed, people now grow obsessed with vacations and relaxation to the point of no return. "Now it remains to be determined what use this world is to us! There aren't seemingly any reports of Kudakks at the scene to investigate, but at the same time there seems to be no rush to! Time to take a closer look at the state of the world now under my control!"

In a strange turn of events, the Zenkaigers find that time is rewinding back to the beginning of their adventures.

"Raise the flags of courage, as you sail across the seven seas! No wait... Worlds! "Mom!" We must do everything we can to find Kaito's mother! Unleash the true powers of Crocodaioh as you voyage from parallel world to parallel world! Venture into an intense battle for Kaito's mom! A battle they cannot afford to lose to Tojitendo! Crossing into various different Topias, perhaps we will come across one that you've been looking for?!"

Tozitend sends Manga World to turn people into manga characters. The Zenkaigers fight back, but Juran and Magine get trapped in a manga and learn they have to survive or else they cannot return. Due to a jealous Zocks breaking off to make his own manga, the remaining Zenkaigers will have to face Manga World by themselves in order to rescue his victims.

The Zenkaigers find themselves overwhelmed by Tennis World, so the World Pirates step in to help improve his allies' tennis skills. Additionally, as the only to defeat Tennis World is to play tennis with him, Zocks challenges the World to a double match with Kaito as his partner and Stacy as Tennis World's.

The Zenkaigers find themselves facing off against Reverbating World and Tozitend hitman Hakaizer, who wields a gun capable of summoning multiple past Sentai members at once. As Secchan recognizes Hakaizer's weapon, Kaito attempts to fight this new enemy by becoming a mummy.

As Tozitend's newest World removes the city's color, leaving everything white in their wake, the Zenkaigers use the Zenryoku Zenkai Cannon to truly come together as the 45th Super Sentai and overcome their latest foe.

Accepting the revelation that Hakaizer is Isao, Kaito tells Zocks, who agrees to help him save Isao. While working on a plan to lure out Hakaizer, the Zenkaigers and World Pirates have to face Bikkuribako World, who keeps making things appear out of random places like their equipment, Stacy, Hakaizer, and Barashitara.

As Tozitend sends a radish-themed World capable of manipulating discarded items to attack the Zenkaigers, Magine and Flint help a little girl who seems to be searching for something.

The Zenkaigers and World Pirates attempt to continue celebrating Kaito's birthday, Christmas, and New Year's, but Shougatsu World attempts to use his powers to make them forget the past year.

Ijirude upgrades Hakaizer and gives him a mecha called HakaijuOh to overwhelm the Zenkaigers. In response, Kaito resolves to face Hakaizer with everything he has and get his father back.

With Isao free of Tozitend's brainwashing, he and Kaito are able to reunite after being separated for so long. However, their reunion is short-lived when they, the Kikainoids, and the World Pirates become embroiled in a culinary competition to determine whether soba noodles or udon noodles are better.

Tozitend sends Kotatsu World to weaken the Zenkaigers and World Pirates' resolve with his namesake, leaving the heat-sensitive Juran to face the new World and Barishitara alone. In desperation, he uses a strange Sentai Gear unconnected to his Sentai predecessors to summon a new hero.

Tozitend sends a weathercock-themed World to use its wind-based powers to overwhelm the Zenkaigers and World Pirates. Stacy seemingly defects from Tozitend to aid the heroes, but they are suspicious of his uncharacteristic smiling and sudden change in sides

The Zenkaigers and the World Pirates encounter SD World, who possesses the Toziru Gear the latter group seeks to cure Cuttaner and Ricky. Even as SD World turns his gear into SD forms along with Kaito's teammates, a determined Zocks stakes everything he has to defeat SD World and finally end his brothers' curse.

With SDtopia and Kaizokutopia freed from Tozitend's clutches, the World Pirates leave to pursue a new journey. However, the Zenkaigers are attacked by Omikuji World, who is capable of manipulating their fortunes.

Using Stacy's body and pretending to be a god, Gege offers the Zenkaigers a way to storm Tozitend's palace and free the remaining captive worlds. To earn their trust, Gege complies with Kaito's request to stop possessing Stacy and, claiming to have precognition, tells them who will be the next monsters they will face. Following his predictions, the Zenkaigers easily defeat Ninjin, Sapphire and Koumori Worlds, including their Dai versions, unaware that all of them were sent by Bokkowaus at Gege's request all while Gege keeps dragging Kikainoids living on Earth back to Kikaitopia. With Stacy freed from Tozitend's grasp, Kaito invites him to live with Yatsude and the others at Colorful, but he rejects the offer. Meanwhile, the World Pirates are at a loss because they could not find out how to dispel Rikky and Cutanner's curse at SDtopia. When they learn that Kaizokutopia was also liberated, Zox becomes suspicious about it. Deceived into believing that Gege is on their side, the Zenkaigers and Stacy agree with his plan to infiltrate Tozitend's palace, unaware that Bokkowaus is fed up with their meddling and decided to take matters into his own hands.

With Stacy free from Gege's control, the Zenkaigers join forces with him and the returning World Pirates to mount an assault on the Tozitend Palace and defeat them once and for all. However, Ijirude stands in their way, having constructed his own giant robot to stop them.

With Ijirude destroyed, the Zenkaigers now face Bokkowaus, who has regained his original form, while Secchan joins the fray to combat Gege. Concurrently, Stacy and Zocks work together to defeat Barashitara, but he proves to be their most difficult opponent yet.

Tozitend was destroyed, Kaito reunites with his parents, and both the World Pirates and Stacy leave to move with their own lives, but Earth and Kikaitopia was separated and Kaito lost his memories of his time with the other Zenkaigers. In search for answers, Kaito comes across an unexpected battle against himself.
