Gamera Forever (2018)

The story picks up where Gamera 3: Revenge of Iris left off, with the JSDF rushing to confront the swarm of Hyper Gyaos invading Japan. Squadron after squadron of fighter jets fall before the monsters. A wounded Gamera takes off from the burning ruins of Kyoto to join the midair battle, where he spins off wild mana shots that pick off a few Hyper Gyaos. The tide of the battle turns when the survivors are joined by the Albino Gyaos, a more powerful, all-white version of the Hyper Gyaos. The entire flock takes aim and fires their supersonic beams on Gamera, causing him to plunge downward to a watery grave.

Following the battle, the Japanese government enlists the help of Nagamine and Osako to help the military search for the new monster. After locating it, the JSDF deploys a large force of tanks, rocket launchers, and helicopters, but the Albino Gyaos proves to be too strong for them. Later, the Albino Gyaos attacks the hotel Osako is staying at, and he is presumed dead in the rubble. Finally, the military pits a heat ray tank, the SGPM-2, against the Albino Gyaos but it, too, fails miserably.

One of the ancient Gamera skeletons is given mana power from Earth and regenerates into a new Gamera. Landing in Yokohama Bay, the new Gamera destroys everything in sight. The Albino Gyaos arrives to attack the new Gamera, and the two engage in a climactic battle, with the former deploying an energy shield and the latter unleashing a pair of plasma sabers. The new Gamera eventually prevails over his arch-nemesis, yet does not return to the sea. Instead, he continues his rampage, destroying and burning everything from Yokohama to Shinjuku. The JSDF launches a last-ditch offensive in Shinjuku using more SGPM-2s, but the new Gamera easily thwarts the attack. Suddenly, a huge explosion erupts from the new Gamera, and central Tokyo is reduced to smoldering ruins.

Afterwards, Osako turns up alive in Okinawa - as far away from Tokyo as possible - wondering how he always manages to survive such calamities. As he hobbles away, a news broadcast is overheard which mentions that the new Gamera opened a crater one kilometre wide and 400 meters deep in the center of Tokyo. The Japanese and U.S. military have found many unclassified prehistoric eggs deep within the crater.
