|This article is about a/an villain in GoGo Sentai Boukenger.|
Furious Demon God Gai (怒りの鬼神ガイ Ikari no Kishin Gai, 17-42): The leader and the evilest of the eastern Ashu Tribe, he is a purple and green demon who can conjure forth a bazooka-like weapon. Gai is a brash and savage demon who loves to destroy, laughing at the sight of others suffering.
Gai and BoukenSilver are bitter enemies because long ago he told a young Eiji that he was part Ashu and that his mother was one as well and because he killed Eiji's father, Karato when he tried to prevent Eiji's Ashu side from growing. When Gai saw Natsuki Mamiya's bracelet he said it was "The Proof of the Chosen One," and he and Hyouga kidnapped Natsuki and used her blood to free Grand Beast Rei from the 100-Demon Mirror. He used Rei's illusion-inducing powers to pose as Satoru Akashi's old companion Masaki to confuse and kill him with the Fighter's Crossbow, however when Satoru confronted his illusion it disappeared.
Though defeated by Eiji (who threw his monk staff at him like a javelin), and terminated by Ultimate DaiBouken and the Ashu Spirit Extinguishing, Arch Priest Gajah resurrected him as Quester Gai (クエスター・ガイ Kuesutā Gai). In this form, Gai wields two guns that also turn into short swords. But in either form, Gai was still Eiji's mortal enemy.
After the Quester's most powerful creation, the Homunculus was destroyed, Eiji and Gai faced each other in a final showdown. In the battle, Eiji finally kills his mortal enemy once and for all, but makes peace with him by building him a grave in memorial.
Super Hero Taisen
Quester Gai and Quester Rei are revived as commanders of Dai-Zangyack. They united with Dai-Shocker and fought against the army of Super Sentai and Kamen Riders. Gai was seen in the backgrounds of the aerial shots fighting HououRanger and Spade Ace, but his fate later is unknown.
Super Hero Taisen Z
Quester Gai was part of an army of resurrected (mostly Super Sentai) monsters led by Space Raider after the revival of Madou Demon King Psycho. They proceeded to attack the gathering of Kamen Riders and Super Sentai, giving them a hard time, with the Questers fighting Kamen Rider Wizard before he joined the Kyoryugers in Kyoryuzin. The heroes of recent years were in a pinch until the arrival of a force of Sentai and Rider reinforcements, which included the Boukenger five-man team, led by Akarenger and Kamen Rider Ichigo. The combined forces of superheroes were able to turn the tide against the Madou army. They lined up and used their various finisher attacks to destroy the revived monsters.
True to his nature, Gai is ruthless and believes himself to be stronger than anyone. Untrustworthy to anyone not a Ashu or his own allies (The Questers), he will betray anyone once his objectives are met. He has a strong rivalry with Eiji Takaoka.
