Thomas and Twilight Sparkle's Adventures of Gamera: Guardian of the Universe

Thomas and Twilight Sparkle's Adventures of Gamera: Guardian of the Universe is an upcoming Thomas & Friends/MLP:FIM/Toho crossover to be created by Hiatt Grey.

Plot
A ship carrying plutonium collides with a floating atoll off the eastern coast of the Philippines, one of many incidents occurring throughout the area. As the anomalous formation approaches Japan, a team of scientists led by Naoya Kusanagi (Akira Onodera) discovers orihalcum amulets and a stone slab covered in Etrurian runes on the atoll. During the investigation, the atoll suddenly quakes, destroying the slab and throwing the scientists into the ocean. One member of the team, Marine Officer Yoshinari Yonemori (Tsuyoshi Ihara), sees the eye and tusk of a giant turtle.

Meanwhile, ornithologist Mayumi Nagamine (Shinobu Nakayama) investigates a village in the Goto Archipelago reportedly attacked by a "giant bird". While Nagamine is initially skeptical of the claims, she is horrified upon discovering human remains in a giant bird pellet. Exploring the nearby forest, her team encounters and then successfully prevents three bird-like creatures from attacking another village. To prevent further attacks, Nagamine agrees to aid the government in capturing the giant birds. The creatures are lured to the Fukuoka Dome baseball stadium, where two of the three are successfully captured. The last one escapes to the harbor, where it is killed by the giant turtle encountered by Yonemori and the scientists. The remaining birds escape before the turtle reaches the stadium.

After translating the runes, Kusanagi explains to Yonemori and his daughter Asagi (Ayako Fujitani) that the giant turtle is called Gamera and the birds are Gyaos. When Asagi touches one of the stone amulets, she inadvertently forms a spiritual bond with Gamera. Kusanagi also tries to convince the government that the Gyaos are the real threat, but they remain focused on Gamera due to the destruction that he caused.

Now working together to investigate the creatures, Kusanagi, Yonemori and Nagamine witness another Gyaos attack at the Kiso Mountain Range. Nagamine and Yonemori are nearly killed trying to rescue a child, but Gamera arrives in time to save them and kills another Gyaos. The last Gyaos, however, escapes. Meanwhile, Asagi discovers that she suffers the same wounds and fatigue as Gamera due to their shared bond. At Mount Fuji, she witnesses a military strike against Gamera. The attack attracts the final Gyaos to the scene, where it grievously wounds Gamera and forces the turtle to retreat into the ocean. Simultaneously, Asagi suffers a similar wound and passes out from the pain. Kusanagi visits his daughter at the hospital where Asagi falls into a coma after saying that she and Gamera must rest.

After consulting with a biologist, Nagamine and Yonemori learn that the Gyaos are genetically engineered and reproduce asexually. They speculate on the origins and purpose of Gyaos and Gamera. Nagamine suggests that Gyaos were awakened by rampant pollution and Gamera was created to combat Gyaos. They approach Kusanagi with this information, explaining that the incident at Mount Fuji shows that Asagi is spiritually linked with Gamera. Kusanagi dismisses these claims until he witnesses the amulet's power himself.

With Gamera recovering in the ocean, the last Gyaos grows unchecked, becoming a Super Gyaos. The creature attacks Tokyo, causing many civilian casualties and prompting the government to focus on Gyaos instead of Gamera. Attempts to kill Gyaos end in failure and it builds a nest in the ruins of the Tokyo Tower.

Upon awakening from her sleep, Asagi warns the others that Gamera has recovered and will attack Gyaos. Gamera catches Gyaos by surprise, destroying its nest and eggs. A massive air battle ensues and Asagi, Kusanagi, Nagamine, and Yonemori follow closely in a helicopter. Initially, Gyaos overpowers Gamera, but Asagi uses her spiritual energy to revive Gamera, who kills Gyaos. Gamera then releases Asagi from their bond and returns to the sea.
