* DropTheHammer:
** Succeeding [=GoldyMarg=] is [[spoiler:[=GoldyDoubleMarg=], which essentially is the same Marg but with a ''second'' Goldion Hammer, plus a pair of giant clackers]].
** Also, [[spoiler:King of Ruin King J-Der docks with GGG's Division Fleet to form the Silverion Crusher]].

* GreaterScopeVillain: It's speculated by Liger that [[spoiler:Triple Zero caused Z-Master to go berserk through the Galeorea Comet, causing it to destroy the Trinary Solar System and launch a war against life itself]]. This would have made Triple Zero

* OddlySmallOrganization: After [[spoiler:Guy's return]], it's revealed [[spoiler:that while all of the Gutsy Galaxy Guard's duties and staff (apart from those left in the Trinary Solar System) had been folded into the Gutsy Global Guard (later retroactively titled GGG Blue to avoid confusion), Chief Yaginuma hadn't retired as was commonly believed, but had stayed on as Chief of the ''Galaxy'' Guard (similarly dubbed GGG Green). And since all the other members (apart from Mamoru and Ikumi) were officially MIA, he was technically the only remaining member of GGG Green until Gai came back. The trope still applies after Guy's return, as while Taiga is reappointed the GGG Green's Chief, with the rest of the group ''incommunicado'', the UN hands over the reins to Guy as [[OverlyLongTitle "Gutsy Galaxy Guard’s Acting Chief-slash-Mobile Corps Captain-slash-only member."]]]]

''The King of Kings: Anime/GaoGaiGar vs. Anime/{{Betterman}}'' (覇界王～ガオガイガー対ベターマン～ / ''Hakaioh: [=GaoGaiGar=] vs. Betterman'') is a Main/WebSerialNovel serialized from September 30, 2016 to March 17, 2021 directly by Creator/{{Sunrise}}'s creative contents team under their HousePseudonym, "Hajime Yatate" and released as a website free-to-read through their collective publishing branch, "Yatate Bunko." It acts as the novelization of the planned but ultimately unproduced ''Anime/BraveSeries'' anime, ''”Project Z,”'' and the official {{crossover}} {{sequel}} to both ''[[Anime/GaoGaiGarFinal The King of Braves [=GaoGaiGar=]: FINAL]]'' and ''Anime/{{Betterman}}''.

*** [[spoiler: The story starts with a married Hatsuno--Ayame Ushiyama giving birth to a son named Hajime, with the meaning of “First.” By the closing of the story, Hana Hatsuno--now as an Amami, gave birth to a child named Tsubasa, with the meaning of “Flight/Wings.”]]

* ZeroApprovalGambit: [[spoiler:The finale has the Bettermen attack the UN base on the moon and then (seemingly) annihilate all of GGG's mobile unit except Final [=GaoGaiGar=], and ''then'' go after the parts of it that are controlled by Guy's human allies until only Guy and Mamoru are left in Final [=GaiGar=] (in reality they've all been sent to a pocket dimension). This turns out to be a ploy to get Gai to awaken the last bit of Triple-Zero within him so he can become the final King of Ruin. This done, they hope to defeat him and allow an Animus Patria seed to grow from Gai's G-Stone, which would allow the Bettermen to move to a new world]].

* AndTheAdventureContinues: [[spoiler: Gai sets off to Jupiter to research, and come up with preventive measures to block Trinity-Zero from affecting Earth]].

*** [[spoiler: The story begins with Galeon sending the infant Latio to The Amamis to become their son, Mamoru. By the closing of ''[=GaoGaiGar=] vs. Betterman'', The Amami Clan reunites with Galeon at that same location to bid it farewell, with Mamoru--now as a new father who choses to stay on Earth to raise his family, and give his blessings to Galeon in hopes it would be the best partner for Gai]].
*** [[spoiler: Gai achieves his original dream of heading out to Jupiter as a researcher--personally piloting a spaceship in his ordinary spacesuit. This time, he has Mikoto, J, Renais, and Galeon accompanying him on the journey]].

* ColorCodedForYourConvenience: [[spoiler:After Gai's return and the reveal that the Gutsy Galaxy Guard technically never disbanded, it's soon realized that there are now two similar organizations with similar names that share an acronym. So to avoid confusion, the Gutsy ''Galaxy'' Guard and the Gutsy ''Global'' Guard are called "GGG Green" and "GGG Blue" respectively after the respective organizations' uniform logo colorings]].

*** Chief of Gutsy Global Guard, Shigeru Akamatsu--late of ''Anime/{{Betterman}}''--is the son of Liger Shishioh, half-older brother of Renais Cardiff Shishioh, nephew of Leo Shishioh, and cousin of Gai Shishioh.
*** Shigeru’s daughter, Sakura is also part of GGG. Due to Shigeru had her later in age ([[SharedFamilyQuirks like his dad and uncle]]) Sakura’s age is close to her [[PracticallyDifferentGenerations Uncle Gai and Auntie Renais]].

* GreaterScopeVillain: It's speculated by Raiga that [[spoiler:Triple Zero caused Z-Master to go berserk through the Galeorea Comet, causing it to destroy the Trinary Solar System and launch a war against life itself]]. This would have made Triple Zero

** [[spoiler: Gai and Mikoto evolved into Evoluders by the ending of their home series. Contrary to the belief that they are similar to Mamoru, revealed in ''FINAL’s'' novel, Evoluders are genetic fusion of humans with a type of alien inorganic compound, which renders them similar to Zonders]].

* ManchurianAgent: The final act reveals that [[spoiler:Gai was one, as it turns out he does in fact have [[TheCorruption Triple Zero]] in his system – it was just being suppressed by his G-Stone. It's only when the Bettermen enrage him that it manifests. [[ZeroApprovalGambit It turns out this was the Bettermen's intention]] so that they could rid him of the "Root of Evil" once and for all]].

* OddlySmallOrganization: After [[spoiler:Gai's return]], it's revealed [[spoiler:that while all of the Gutsy Galaxy Guard's duties and staff (apart from those left in the Trinary Solar System) had been folded into the Gutsy Global Guard (later retroactively titled GGG Blue to avoid confusion), Chief Yaginuma hadn't retired as was commonly believed, but had stayed on as Chief of the ''Galaxy'' Guard (similarly dubbed GGG Green).

** Gai is in the same age group as Renais due to his father Leo marrying late in age under May-December romance, with his mom giving birth to him in average settings.

* VersusTitle: As the name implies, the story has various characters and tech from ''[=GaoGaiGar=]'' facing off against their counterparts from ''Betterman'', with [=GaoGaiGo=] being made using neuronoid tech and being supported by members of the cast from ''Betterman'' facing off against the [[DemonicPossession demonically possessed]] heroes and mechanoids from ''[=GaoGaiGar=]'', and Lamia seeming to have some kind of umbrage with Gai as well. However, it's not until the final act that [[spoiler:the Bettermen and [=GaoGaiGar=] itself actually face off]].
