==== Tokuma Shoten ====
In the 1995 series reboot by [[Tokuma Shoten]], ''[[Gamera: Guardian of the Universe]]'', three [[Gyaos]] are discovered on a remote island. The Japanese government discovers that they are all female and decides that since they are the last of their kind, they should be captured and studied. Meanwhile, scientists search for a moving atoll in the Pacific. When the atoll is located, small gems made of an unknown metal are discovered on it, as well as a stone that protrudes from the center of the island. The scientists take pictures and collect some of the strange gems, but the stone crumbles and the atoll moves off towards Japan at high speeds. The atoll is found to be an ancient monster of Atlantean origin called Gamera. He attacks the Gyaos; two are killed, but one escapes. The remaining Gyaos grows to Gamera-like proportions and returns to resume the battle. Gamera defeats this foe and heads out to sea.

In ''[[Gamera 2: Attack of Legion]]'', released in 1996, Gamera defends the [[Earth]] from attacks by an alien force known as [[Legion (kaiju)|Legion]] ([[:ja:レギオン (架空の怪獣)|jp]]).

In ''[[Gamera 3: Revenge of Iris]]'', released in 1999, Gamera has to face hordes of Gyaos Hyper and a new foe known as Iris which is a subspecies of Gyaos. [[Shusuke Kaneko]] originally wanted to end the film with Gamera's victory against the swarms of Gyaos, however his idea was cancelled partially due to budgetary problems.<ref name=KanekoDiary />

[[Yasuyoshi Tokuma]] ([[:ja:徳間康快|jp]])'s proposal for a crossover with [[Godzilla]] didn't materialize,<ref name=Kaneda /><ref name=MagMix /> and "G4" was cancelled,<ref name=MWP /> and Tokuma Shoten eventually disposed Daiei Film properties due to Yasuyoshi's death in 2000 and the financial condition of the company.<ref name=Nikkei />

The 2003 [[independent film]], ''[[GAMERA 4-TRUTH]]'' ([[:ja:ガメラ4 真実|jp]]), which presumably reused the scrapped plot of "G4", was produced by Shinpei Hayashiya ([[:ja:林家しん平|jp]]) with featuring [[Yukijirō Hotaru]].{{refn|His teacher, Yukitarō Hotaru's appearance in ''[[Gamera vs. Gyaos]]'' was the main reason for Yukijirō's involvements in the Heisei Gamera trilogy.<ref name=Perfection />|group="note"}} Tokuma Shoten gave a permission to it under the condition to not to take fees, and it has been repeatedly co-screened with canonical ''Gamera'' films on occasions.<ref name=Imai/>

In early 1990s, there existed attempts to produce new productions which were different from the Heisei trilogy. [[Niisan Takahashi]] independently developed an idea as the later basis for ''Gamera vs. Phoenix'',<ref name=Stuart /><ref name=DaieiScripts /> where he had experienced a discord against Tokuma Shoten for the production of ''[[Gamera: Guardian of the Universe]]'' and severed ties with all stakeholders.<ref name=YuasaInterview /> There was also a new [[Direct-to-video#OVA and V-Cinema in Japan|V-cinema]] project around 1991.<ref name=EigaHiho2021 /> Prior to the production of ''[[Gamera 3: Revenge of Iris]]'', there existed a film project ''"Gamera 2.5"''{{refn|Two subsequent Heisei-trilogy-based manga, ''Gamera vs. Barugon: Comic Version'' ([[:ja:大怪獣激闘 ガメラ対バルゴン COMIC VERSION|jp]]) and {{Nihongo|''Gamera Side Story: Version 2.5''|ガメラ外伝 Ver 2.5|Gamera Gaiden Bājon 2.5|lead=yes}}, instead bore the number "2.5".<ref name=Perfection />|group="note"}} by [[Shusuke Kaneko]] and [[Kazunori Ito]] and others due to [[Shinji Higuchi]]'s reluctance to participate in the 1999 film. Its plot never involved Gamera directly, and instead focused on a juvenile Gyaos attacking on a depopulated, mountainous village, and aged villagers resisting the monster. Higuchi eventually joined the 1999 film due to the cancellation of the project by [[Mamoru Oshii]]{{refn|Oshii and various members of the Heisei Gamera trilogy, including Kaneko and Ito and Higuchi, have had connections since before the production of the Heisei trilogy. Oshii's works, such as ''[[Urusei Yatsura]]'', which have had occasional associations with the ''Gamera'' and ''Daimajin'' franchises, and other scrapped projects, influenced the production of the Heisei trilogy, and Oshii was at one point supposed to join the trilogy.<ref name=EigaHiho2021 /><ref name=Ono2018 />|group="note"}}, which was the preceding project of ''[[Garm Wars: The Last Druid]]'' (2014).<ref name=Perfection /><ref name=EigaHiho2021 />

==== Kadokawa Corporation ====
In ''[[Gamera the Brave]]'', the first reboot attempt by [[Kadokawa Corporation]] released in 2006, Gamera (Avant Gamera and Toto) battles a flock of Original Gyaos and Zedus, a [[mutant]] kaiju under the influence of Gyaos.<ref name=BravePamphlet /> It was initially intended to be a [[Crossover (fiction)|crossover]] with [[Godzilla]], and the company also initiated reboot attempts of ''[[Daimajin]]'' and ''[[Yokai Monsters]]'', and the 2005 film ''[[The Great Yokai War]]'' was produced.<ref name=Perfection /><ref name=Karasawa /><ref name=Zakzak /><ref name=Aiken /> Afterward the 2006 film, [[#Influences of the Heisei Trilogy|various subsequent productions including its sequels]], along with a ''Daimajin'' project were cancelled, and ''[[Daimajin Kanon]]'' was instead produced.<ref name=Nezura1964 />

In March 2014, [[Anime News Network]] reported that a new ''Gamera'' production was planned, with no release date specified.<ref name=ANN>{{cite web|last=Loo|first=Egan|url=https://www.animenewsnetwork.com/news/2014-03-12/new-gamera-project-listed-by-retailer|title=New Gamera Project Listed by Retailer|date=12 March 2014|website=Anime News Network|access-date=7 July 2019}}</ref>

At the [[New York Comic Con]] held in October 2015, [[Kadokawa Daiei Studio]]'s senior managing director Tsuyoshi Kikuchi and producer [[Shinichiro Inoue]] ([[:ja:井上伸一郎|jp]]) screened a full proof-of-concept film in honor of the franchise's 50th anniversary; the short was directed by [[Katsuhito Ishii]] and its music was composed by [[Kenji Kawai]].<ref name=CGWORLD /><ref name=WebNewType>{{Cite web |title=ガメラ50周年映像を手がけた石井監督を直撃 (前編) |url=https://webnewtype.com/report/article/67391/ |access-date=2022-04-09 |website=WebNewtype |language=ja}}</ref> The proof-of-concept film featured a newly designed Gamera, a swarm of newly designed Gyaos and a new, as yet unnamed monster, all of which were created and rendered through the use of [[computer-generated imagery]].<ref name=amaya>{{cite web|last=Amaya|first=Erik|url=https://www.bleedingcool.com/2015/10/09/nycc-15-gamera-is-still-the-friend-of-all-children-in-new-trailer/|title=NYCC '15: Gamera Is Still The Friend Of All Children In New Trailer|date=9 October 2015|website=Bleeding Cool|publisher=Avatar Press|access-date=7 July 2019}}</ref><ref>{{cite web|last=Loo|first=Egan|url=https://www.animenewsnetwork.com/news/2015-10-09/new-gamera-monster-cg-footage-unveiled-by-katsuhito-ishii/.93952|title=New Gamera Monster CG Footage Unveiled by Katsuhito Ishii|date=9 October 2015|website=Anime News Network|access-date=7 July 2019}}</ref><ref>{{cite web|last=Chapman|first=Paul|url=https://www.crunchyroll.com/anime-news/2015/10/09-1/video-teaser-trailer-for-new-gamera-film-directed-by-katsuhito-ishii|title=VIDEO: Teaser Trailer for New "Gamera" Film Directed by Katsuhito Ishii|date=9 October 2015|website=Crunchyroll|access-date=7 July 2019}}</ref> It has been rumored since the film's showing at New York Comic Con that it was never completed.
