Gamera 3: Revenge of Iris

Gamera 3: Revenge of Iris (ガメラ3 邪神〈イリス〉覚醒, Gamera Surī Irisu Kakusei; literally "Gamera 3: Evil God Iris Awakens") is a 1999 Japanese kaiju film directed by Shusuke Kaneko, with special effects by Shinji Higuchi. Produced by Daiei Film and distributed by Toho, it is the 10th film in the Gamera series and the third in the franchise's Heisei period, following 1996's Gamera 2: Attack of Legion.

The story takes place three years after Gamera defeated the Legion. The world faces a new threat from evolved Hyper Gyaos. Ornithologist Mayumi Nagamine returns to help the Japanese government. Meanwhile, a graveyard of Gamera fossils is discovered at the bottom of the Pacific Ocean. Two government agents, occultist Mito Asakura and Kurata Shinya, work on their own agenda, with Asakura believing Gamera is an evil spirit. In Shibuya, Gamera kills two Hyper Gyaos with little regard for human life, causing up to 20,000 casualties, leading the government to order Gamera's destruction.

Teenager Ayana Hirasaka, whose parents were accidentally killed by Gamera during his 1995 battle with Super Gyaos, finds a stone egg sealed in a temple. The egg hatches a tentacled mutant creature called a "Ryu-sei-cho," which she names Iris after her deceased cat. Through an orichalcum magatama amulet, Ayana forms a psychic bond with Iris and plans to use him for revenge. As Iris grows, he tries to absorb her. Her classmate Tatsunari Moribe frees her with a sacred dagger, but Iris later massacres half of Asuka's population and matures into his adult form.

The JGSDF fails to destroy Iris, who flies toward Kyoto, where Ayana has been taken by Asakura and Kurata. They plan to use her to summon Iris. During the journey, Iris attacks two JASDF F-15J pilots, but Gamera intervenes. Gamera is hit by air-to-air missiles from the F-15s, allowing Iris to escape. At Kyoto Station, Nagamine and Asagi Kusanagi, a former psychic link to Gamera, try to extract Ayana as a typhoon hits. Kurata theorizes Gamera was engineered as humanity's guardian, powered by collective "mana," and that Iris was created to defeat Gamera so Gyaos could wipe out humanity. Nagamine and Asagi reject his misanthropy but find his theory plausible.

Iris reaches Kyoto Station and battles Gamera. Iris impales Gamera with a tentacle and destroys the station, killing Asakura and Kurata.
