All spoilers for Zyuden Sentai Kyoryuger, Ohsama Sentai King-Ohger, and their crossover episodes are unmarked. You Have Been Warned!

In the midst of pursuing Dadged with Daigo, Utsusemimaru ends up in an alternate dimension where Deboss invaded, having been unable to stop the Galactinsect King. While he tries to get back to his own Earth, he accidentally interferes with the main timeline and ends up creating an altered timeline where the Ohsama Sentai have radically altered identities, including Gira as the Galactinsect King ruling over Tikyū! Now it's up to the combined forces of the Kyoryugers and the Ohsama Sentai to fix this catastrophe before it's too late!

Tropes

• Alternate Self: The main plot focuses on the Kyoryuger meeting alternate versions of the King-Ohgers, among them being Gira as the Galactinsect King.
• Back from the Dead: Torin returns with Ramirez and Tessai to deal with Grodie.
• Bad Present: Due to Utchy messing with the timeline, the history of Tikyū is changed to one where Gira eventually became the Galactinsect King with Jeramie working for him, while the other kings no longer rule their respective kingdoms.
• Badass Family: Prince fights alongside his parents Daigo and Amy, along with the rest of the Kyoryugers.
• Big Damn Heroes: Daigo reappears to help Utchy and Prince after the timeline changes makes him no longer stuck in amber.
• The Bus Came Back: As shown in the previews, Daigo and Utchy make their return out of suit along with Yayoi, Daigo's father, and Torin. Ramirez and Tessai also appear in-suit.
• Call-Back:
  • At the start of the film, Daigo gets encased in amber like Dagded had mentioned doing before to other planets.
  • Galactinsect!Gira possesses his own monstrous version of Kuwagata Ohger like Reiniol does, albeit in red.
  • Prince's cameo in #40 is revealed to be him retrieving Gabutyra for the final battle.
• Cerebus Retcon: Prince asking Gira to remain a kind evil king is due to him already having seen him evil.
• Chekhov's Gun: To restore the King-Ohgers' memories, Daigo borrows the Venomix Shooter that Jeramie was using to record the King-Ohgers' story in the finale.
• Enemy Without: After Gira is knocked back to normal, his evil form is separated from him, setting him up as the final boss along with the Jesters.
• Fading Away: Prince is shown fading in and out as a result of the timeline being messed up.
• How the Mighty Have Fallen: Due to Utchy’s interference with the main timeline, the King-Ohgers sans Gira (who became evil instead) and Jeramie (who never had the chance to experience kinghood) experienced some form of this in the 17 year interim between the Fury of the Gods and the present.
  • Yanma’s technology skills severely faltered, meaning that N’Kosopa was never able to revitalize under his rule. He instead became the owner of the scrapyard, and a very bad one at that if Shiokara easily pushing him around is any indication.
  • Hymeno was overthrown because her people quickly grew tired of her selfishness, leading to her becoming a flower vendor. Her sullied reputation causes people to not buy her flowers however, so she resorts to eating them instead out of desperation.
  • Subverted with Rita. While Rita did have to step down as Chief Justice because of mental fatigue, they managed to become a top idol instead. Because they don’t have to deal with the stress of keeping up the policy of absolute neutrality, they became far bubblier and seemingly much happier.
  • Kaguragi’s various deceptions were eventually found out by the other countries and his people, leading to him being overthrown. He does rigged sumo matches with Suzume to get by, not that it really helps much.
• How We Got Here: The movie opens with Evil!Gira about to slay the kings.
• Nerd Glasses: Yanma wears these in the altered timeline to symbolize how much of a loser he became. He promptly loses them when he gets his memories back.
• Nice Job Breaking It, Hero: The altered timeline occurs after Utchy allows a young Gira to consume more Shugod souls due to not knowing what rainbow jujurira really is. As a result he ends up killing Dagded and talking his place as the Galctinsect King.
• Strong Family Resemblance: During the post credits scene, Utchy returns Prince home, where it's revealed Future!Daigo looks just like his father. Utchy, however, doesn't realize it and assumes he somehow made Prince's father his grandfather. He promptly freaks out and runs away screaming to Yayoi he thinks he messed up again.
• Surprisingly Realistic Outcome:
  • In the main timeline, Hymeno’s insistence on being selfish is just an amusing quirk. In the Evil King!Gira timeline, the common people quickly got sick of her It's All About Me attitude and overthrew her when they could.
  • Kaguragi's people and the other countries discovered his lies and promptly kicked him off the throne when they could.
• Theme Song Power Up: The groups' main themes playing during the final battle, along with some old Kyoryuger insert themes.
• Unwitting Instigator of Doom: Under a mistaken belief that rainbow jujurira is a simple dessert, Utchy somehow managed to find a giant supply of it to feed to Gira since Gira wanted more of it. This directly led to Gira becoming a powerful enough Tyke Bomb to somehow kill Dadged without any repercussions.
