All spoilers Kyōryū Sentai Zyuranger, Bakuryuu Sentai Abaranger, and Tokumei Sentai Go-Busters, are unmarked. You Have Been Warned!
Zyuden Sentai Kyoryuger vs. Go-Busters: The Great Dinosaur Battle! Farewell, Our Eternal Friends is the crossover between Zyuden Sentai Kyoryuger and Tokumei Sentai Go-Busters, as well as including a grand team-up between Kyoryuger and the previous two Dinosaur-themed Super Sentai: Kyōryū Sentai Zyuranger and Bakuryuu Sentai Abaranger.
It was adapted for American audiences as the Power Rangers Beast Morphers season 2 three-parter "Finders Keepers"/"Making Bad"/"Grid Connection".
This movie contains examples of the following tropes:
- Applied Phlebotinum: Dino Hope, the transcendent power of the dinosaurs that is shared among the three Dino teams. Its Evil Counterpart is Wicked Life Energy, a malevolent force that Voldos needs to gain full power, made by corrupting Dino Hope.
- Back from the Dead: Both Enter and Escape are brought back by a one-time Vaglass restoration program activated in response to Voldos's emergence. The same program also brings back Masato temporarily, allowing him to fight with the Go-Busters again.
- Big Bad: Space War God Voldos, who is said to have been born from the combined hatred of previous Big Bads Great Satan and Wicked Life God Dezumozorlya.
- Co-Dragons:
- As a being created from the hate of dinosaurs and Super Sentai, Voldos creates two generals based on those fought by the Zyurangers and Abarangers respectively: Neo-Grifforzer note and Neo-Geildon note .
- Enter & Escape are also a pair of Co-Dragons to Voldos, having been revived by a one-time restoration program that he activated.
- Continuity Nod: Hiromu thanked Daigo for helping out him and Gokai Red before, a reference to him and his team's Early-Bird Cameo in Go-Busters vs. Gokaiger, not able to do so during Super Hero Taisen Z due to not having time to do so due to needing to focus on their enemies.
- Dancing Theme: Wouldn't be a Kyoryuger movie without one, this time with not only the Go-Busters, but also the Kyoryuger and Go-Buster allies, the villains, and the previous dino teams.
- Demoted to Dragon: The Vaglass are revived under the control of Voldos, with Enter & Escape becoming Co-Dragons to him alongside Neo-Grifforzer & Neo-Geilton.
- Demoted to Extra: Zig-Zagged with the Go-Busters. While this Vs. Movie breaks tradition by not having the Go-Busters actually transform and battle alongside the Kyōryūgers on the field (with that honor instead going to the other two dinosaur teams), they are not completely Out of Focus, as they get plenty of screen time & action, and they do contribute to the plot.
- Designated Girl Fight: Yoko and Amy team-up to fight Escape.
- Dragon Their Feet: Neo-Geildon outlives his master and uses Messiah Card 13 to go One-Winged Angel and become Neo-Messiah, only to be defeated by the ToQgers.
- Early-Bird Cameo: This movie also features the debut of Ressha Sentai ToQger.
- Evil Costume Switch: The Kyoryugers sport black outerwear once they lose their Dino Hope.
- Fake Shemp: Every Ranger gets a return from their original actor, but the Zyurangers other than Geki and Ranru only provide their voices rather than appearing out of suit.
- In the Name of the Moon: Uniquely, the combined Vs. roll call is that of the Kyoryu Super Sentai, working backwards from Kyoryuger to Abaranger to Zyuranger. The Go-Busters do a roll call seperately.
- Legacy Character: Neo-Grifforzer and Neo-Geidon are "embodiment clones" of the original Grifforzer and Geildon. Neo-Geildon later uses the recreated Messiah Card 13 to become an embodiment clone of Messiah, dubbed Neo-Messiah.
- Make My Monster Grow: When the Kyōryūgers are giving Neo-Geildon trouble, Neo-Grifforzer jumps in and asks Voldos to help them out. Voldos enlarges Neo-Grifforzer to giant size to deal with them.
- Mooks: In addition to the Deboss Army's Zorima and the revived Vaglass' Buglers, Voldos has his own force of Bandora Golems and Evolian Barimas, forming one large foot soldier army.
- Mythology Gag:
- This movie shares some similarities with Go-Busters vs. Gōkaiger. The Kyōryūgers being forced to work for the villains (while wearing new black outfits) and the use of time travel in the plot are examples. Also, this movie has a plot-relevant role reprise from Yukito Sanjō, while Go-Busters vs. Gōkaiger had a plot-relevant role reprise from Princess Kaoru Shiba. Both were their respective teams' representatives in those seasons' tribute episodes of Gōkaiger.
- Speaking of prior Vs. Movies, the above mentioned Continuity Nod is itself a Mythology Gag to a Continuity Nod from a previous Vs. Movie. In Dekaranger vs. Abaranger, the Big Bad of that Vs. Movie briefly disguised himself as HurricaneRed, who Ryōga recognized from the previous one, Abaranger vs. Hurricaneger. In this Vs. Movie, Hiromu mentions Daigo helping him and GōkaiRed in the previous Vs. Movie, Go-Busters vs. Gōkaiger. Both this Vs. Movie and Dekaranger vs. Abaranger contained a mention to the red ranger from the season before the two featured ones. Coincidentally, all of the mentioned Vs. Movies featured some element of the Abarangers' series.
- Speaking of Abaranger, the evil essence that Voldos feeds on, Wicked Life Energy, is probably named after the full title of Abaranger's Big Bad, Wicked Life God Dezumozorlya, who was one of Voldos's predecessors.
- Speaking of villains who preceded Voldos, when Voldos enlarges Neo-Grifforzer to giant size, he does it by sending to the ground a wand just like Witch Bandora's wand (which incidentally is the source material for the Trope Namer, Rita Repulsa's magic wand).
- Speaking of indirect references to Power Rangers...
- Geki's updated transformation sequence is reminiscent of the one Adam Park had in Once a Ranger.
- Neo-Grifforzer calling out the forces of Voldos for the climactic battle is translated by one fan sub as, "Come forth, our united alliance of evil!"
- Out of Focus: Downplayed. Compared with the Kyoryugers and dino teams, the Go-Busters don't get a whole lot of significant focus in the actual team-up fight and climax, but they do contribute significantly to the plot progression due to their actions and help out the Kyoryugers with the final mecha fight.
- Paint It Black: To signal that the Kyoryugers have turned evil all of them decide to take a piece out of Ian's wardrobe.
- Sealed Evil in a Can: Voldos is initially sealed in some sort of asteroid, and he needs Wicked Life Energy in order to properly revive.
- Spotlight-Stealing Crossover: The movie is heavily marketed on the novelty of the three dinosaur Sentai teaming up and battling alongside each other, leaving the Go-Busters largely uninvolved with the team-up battle that is the main selling point of the Vs. Movies. As if to compensate for this, the rest of the movie outside of the actual team-up battle gives plenty of screentime and focus to the Go-Busters, with them taking an active role in advancing the plot leading up to the team-up and getting a respectable amount of action scenes of their own, including the very first action scene and several Big Damn Heroes moments.
- The Stinger: The movie has the ToQgers making their appearance... after the end credits. Makes you wonder how many people in theaters missed their cameo.
- Transformation Sequence: Rare for a Vs. movie, the Kyoryugers use their stock footage transformations, while TyrannoRanger and AbaRed both had new sequences filmed for the movie.
- Versus Title: In this case, the Vs. element comes from TyrannoRanger and AbaRed showing up Brainwashed and Crazy, followed by the Kyoryugers. Also we get a fight scene between the five Kyoryugers and Enter's Evil Red Buster form.
- Villain Team-Up: As well as raising an army created from the hatred of the Zyurangers' and Abarangers' old enemies, Voldos allies with both the revived Vaglass and the Deboss Army.
- Why Did It Have to Be Snakes?: During the Go-Busters' first meeting with Torin, Hiromu starts getting nervous due to his resemblance to a chicken.
