Iris's History
Iris began his life as a stone egg, sealed within a small underground temple in the village of Minami-Asuka, Nara and guarded over by a family line named Moribe. Local legend said it was the resting place of a demon called Ryuseicho. A stone of unknown origin was said to keep the demon dormant as long as it is not moved.
A young girl named Ayana Hirasaka, left an orphan by the 1995 Gamera and Super Gyaos battle and blaming Gamera for her parents' deaths, entered the cave on a dare and moved the stone. In the process she and the latest son of the Moribe line discovered both the egg and a magatama, similar to the one that linked Asagi Kusanagi to Gamera in 1995. The egg later hatched into Iris' first form.
Ayana gained a link to the creature via the magatama and felt a kinship with him, stating at one point "Gamera killed his family too." Driven by total hatred for Gamera, she raised Iris, naming him after her pet cat which had perished along with her parents, in the hope that he would become strong enough to kill Gamera for her. He displayed affection toward Ayana, though he preyed upon woodland animals and drained their blood for food.
It was not long before Iris, now grown into his second form, attempted to merge with Ayana by sealing her in a cocoon. Moribe discovered her and cut her free. She was then taken to a hospital. While Ayana was gone, Iris grew into a giant monster in the woods as he preyed upon several villagers, including Ayana's adoptive family. Shortly after, the monster grew into his third form, continuing to feed on any humans unlucky enough to stray too close to his location among the trees.
The JSDF quickly deployed and surrounded Iris as he slept, attempting to take him out with machine guns and bazookas. The weaponry only seemed to irritate the creature. During the fight, in which several of the soldiers were killed and several more were severely injured, Iris took to the sky and headed for Kyoto, where Ayana had been transferred earlier. The JASDF sent two F-15 Eagles in an attempt to shoot Iris down, but he was able to evade them and almost destroyed them after getting in position behind the aircraft to counterattack. Before Iris could do so, the fighter pilots were saved by the sudden arrival of Gamera, who engaged Iris in a mid-air battle. As the JSDF had been given orders to attack Gamera should he appear again following his battle with the Hyper Gyaos in Shibuya, MIM-104 Patriot surface-to-air missile launchers shot at Gamera and slowed him down, inadvertently allowing Iris to continue on to Kyoto.
Soon, Iris landed in Kyoto with Gamera in pursuit. Iris battled Gamera through the city toward Ayana's location at Kyoto Station, all while Ayana watched and commanded him to kill Gamera. Iris managed to impale Gamera with his arm blade, leaving him incapacitated, and then attempted again to merge with Ayana. When Moribe intervened, the creature swatted him aside and sucked Ayana into his body against her will. While inside, Iris presented Ayana with recounts of his memories of killing her adoptive family. After witnessing this, Ayana realized that she fueled Iris' destruction with her hatred, and recalled the events that led to her becoming an orphan as they actually took place. Contrary to what she had believed, Super Gyaos instead of Gamera was the one who killed her parents. All seemed lost until Gamera suddenly punched through Iris' chest and ripped Ayana out.
Infuriated, Iris pinned Gamera's hand to a wall with his spear hand and began to absorb Gamera's energy. His tentacles began to form plasma fireballs, but Gamera quickly used a plasma fireball himself to sever his own hand. Iris fired the absorbed plasma fireballs at Gamera who used his stump to turn the plasma into the Banishing Fist. Gamera then used the fist to punch Iris through the wound he had made by retrieving Ayana, discharging incredible amounts of energy into Iris's body. Iris shrieked in agony, before becoming consumed in a massive explosion that blew apart most of what remained of Kyoto Station's concourse. Victorious, Gamera stood atop what was left of Iris's body, and set down the capsule that held Ayana.
