Zyuden Sentai Kyoryuger
In the time of dinosaurs, the Deboss Army invaded Earth and almost made the extinction of the dinosaurs but they were defeated by Wise God Torin and the Zyudenryu during the first invasion. In the present day, the Deboss Army resurface as they continue their invasion. To stop them, Torin chooses five brave individuals who must defeat their respective Zyudenryu first in order to get their powers to become the "People of the Strong Dragons", the Kyoryugers. The Kyoryugers are five young warriors along with their partner Zyudenryu. Prior to battle, the team announces their arrival by saying "The World's Strongest Brave, Zyuden Sentai Kyoryuger!" The Kyoryugers are based out in a secret base called the Spirit Base located near the Earth's core and the Tiger Boy family restaurant acts as their civilian hangout.
Later on, Tessai/Kyoryu Gray the first Kyoryuger on Earth makes himself known to the team. The team learns his technique. Doctor Ulshade defeated Plezuon, become Kyoryu Violet, and invented and mass-produced the Kyoryugers' Zyuden Arms weapons with his voice programed into them. Once fulfilling a six-month expedition to space, Ulshade returns to Earth to entrust Plezuon to the Kyoryugers before ending up in the hospital due to throwing our his back. He passes the title of Kyoryu Violet onto his granddaughter Yayoi. After being reunited with Bragigas, Torin gains the Giga Gaburivolver 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, Torin gains the ability to become Kyoryu Silver to aid the Kyoryugers. 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 Torin. Though Torin attempted to help in stopping Deboss's evolution, he is defeated and then killed by Daigo's father Dantetsu as Deboss's intent for him to die as a renegade member of the Deboss Army rather than as Kyoryuger. However, Torin having met up with Dantetsu prior, this was actually part of their plan to defeat the Deboss Army as Torin proceeds to fight his way through the deceased Debo Monsters to destroy Deboss Hell so Deboss' death would be permanent.
Ramirez later chooses Daigo's sister Yuko to be the new living Kyoryu Cyan. When she is introduced to the Kyoryugers for the first time, Nobuharu tries to explain things to her, but she reveals to him she has known the truth for some time. Amy meets the kind Shinya with who Tessai realizes must be his descendant in the modern era and makes him his replacement as the living Kyoryu Gray. When setting his final plans of planetary genocide in motion with the Darkness Clock, Deboss uses his dark melody to prevent the Kyoryugers from transforming while sending his minions to dispatch them before they use the empowered Maximum and Victory Zyudenchi on him. With the other Kyoryugers remaining behind to hold off the Deboss Army, pushing Amy out of harm's way, Daigo confronts Deboss himself. Though overpowered, Daigo becomes empowered by the Earth's true melody and that of his friends as he uses Kyoryu Carnival with the Maximum and Victory Zyudenchi to finally destroy Deboss while the Zyudenryu destroy the Frozen Palace.
In the year 2114, one hundred years after the adventures of the previous Kyoryuger team and during the events of Zyuden Sentai Kyoryuger Returns: 100 Years After, Canderrilla and Luckyulo recruit a new team of Kyoryugers to fight the revived members of the Deboth Army. Though they originally have different Zyudenryu partners (with the exception of Nobuta-san), the Kyoryugers inherit the roles of their ancestral predecessors when they meet them, and a youthful version of Souji, face-to-face.
