Gamera 4: Truth
Gamera 4: Truth (ガメラ4 真実 is a fan-made sequel to Gamera Fō Shinjitsu)Gamera 3: Revenge of Iris. It has never been released on home video, and is rarely shown in public since a series of free screenings in Japan in 2003.
The story picks up where Gamera 3: Revenge of Iris ends, with the JSDF rushing to confront the swarm of 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 Gyaos. The tide of the battle turns when the survivors are joined by Albino Gyaos, a more powerful, all-white version of the Hyper Gyaos. All take aim and fire their supersonic beams on Gamera, plunging him 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 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 Gyaos, but it too fails miserably.
One of the ancient Gamera skeletons is given mana power from the earth and regenerates into a new Gamera. Landing in Yokohama Bay, Gamera lays waste to everything in sight. Albino Gyaos arrives to attack Gamera, and the two engage in a climactic clash, with the former deploying an energy shield and the latter unleashing a pair of plasma sabres. The new Gamera eventually prevails over his arch nemesis, yet does not return to the sea. Instead, he continues on a rampage, stomping and burning everything from Yokohama to Shinjuku. The JSDF launches a last-ditch offensive in Shinjuku using more SGPM-2s, but Gamera easily thwarts the attack. Suddenly, a huge explosion erupts from 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 kilometer wide and four hundred meters deep in the center of Tokyo. The Japanese and U.S. military found many unclassified prehistoric eggs deep within the crater.
