Torin is the humanoid bird-like mentor of the Kyouryuugers. He was the one who gave the dinosaurs the power to become the Zyudenryu during the first invasion of the Deboss Army. When the Deboss Army returns to Earth, he seeks out five youths to become the "People of the Strong Dragons", or the Kyouryuugers.
Originally known as Demon Sword High Priest Torin (魔剣神官トリン Maken Shinkan Torin), he was a member of the Deboss Army who was created to attack Earth as a first wave. However, Torin came to love the planet's beauty and resolved to protect Earth's life forms. Though he was unable to save the dinosaurs from the mass extinction caused by the invasion, and watched his partner Bragigas sacrifice himself to damage their enemy's heart, Torin managed to freeze Deboss's body while scarring his older brother Chaos. Mortally wounded from the battle, Torin used what remained of Bragigas to create the Spirit Base under the "Golden Land", the mass of land that would become Japan, and dedicated himself to keep the Deboss Army from fully resurrecting. Having met a race of prehistoric people who lived alongside the dinosaurs and hearing their music, Torin was inspired to form the Kyouryuugers to fight the Deboss Army whenever they resurface over the ages. Other than teleportation, Torin can sense Deboss cell-based beings like himself, fire energy orbs, and wield his Feather Edge sword in battle. Torin has a habit of snapping his fingers whenever he says the word Brave (ブレイブ Bureibu). Despite having considerable power and combat prowess, Torin is unable to fight for extended periods because of injuries sustained during his last battle with the Deboss Army. If he is outside the Spirit Base for too long and exerts himself too much, his wings will turn to stone and he will eventually be unable to move. He is sustained by healing inside the Spirit Base. Torin created Utsusemimaru's Gaburi Changer and Zandar Thunder, an action that he notes was incredibly draining, and thus very grateful that Doctor Ulshade invented the modern Kyoryugers' Zyuden Arms.
Torin ultimately kept his origins a secret from the Kyouryuugers until Chaos formulates a scheme with Endolf to not only satisfy his own revenge, but also to expose his younger brother's true nature to the Kyouryuugers by using Canderrilla to revive the darkness within Torin. Forcefully enlarged, Torin only regains enough control of himself to force Kyoryuzin's Goren Zyudenken through his body. On the verge of dying, he explained that he was no exception to what he said about anything that could lead to Deboss being resurrected and he had no regrets. Torin effectively dies afterwards as he reverts to his original size while petrified. However, singing "Dino Soul" in conjunction with the gathered Lost Stones, the Kyouryuugers manage to revive Torin. Though they now know Torin's true origin, the Kyoryugers continue to have faith in and stand by him, which touches him greatly. After being reunited with Bragigas, Torin gains the Giga Gaburivolver (ギガガブリボルバー Giga Gaburiborubā) as a means to enter the Spirit Base once it is reintegrated back into the Zyudenryu. However, due the events of the past with Chaos and Mad Torin mentioning it, Torin thought himself unfit to truly be Bragigas' partner as due to him being the scion of Deboss, he believes that he lacks the ability to manifest Brave. Yayoi convinces him otherwise, stating that he is not as weak as he thought himself to be. With Daigo's reminder of what Brave is later, he realizes that his body became weak due precisely due to Brave manifesting within him. Accepting now that he is now more an embodiment of Brave than a scion of Deboss, beginning when he sided with the dinosaurs and humans over the ages, Torin gains the ability to become KyouryuuSilver (キョウリュウシルバー Kyōryū Shirubā) to aid the Kyouryuugers. As KyouryuuSilver, able to use the Feather Edge in his Torinity Straizer (トリニティストレイザー Toriniti Sutoreizā) attack, he introduces himself as the "Shining Brave" (閃光の勇者 Senkō no Yūsha). With the help of Tessai temporarily altering the Maximum Zyudenchi, Torin once takes on a human form to help Souji with his parents under the alias of Torii (鳥居?). Though Torin attempted to help in stopping Deboss's evolution, he is defeated and then killed by Dantetsu as Deboss's intent for him to die as a renegade member of the Deboss Army rather than as Kyouryuuger.
