In order to combat Resentful Knight Endolf, Yayoi comes up with a new Zyudenchi for Kyoryu Red that would increase his powers. Unfortunately, the new Battery accidentally causes him to act more like Gabutyra.
While telling Ian that Torin expected the Deboth Army was not truly defeated as they believed, Daigo admits he needs to talk to Torin about the mysterious sack. However, Torin alerts them to Dogold attacking the city. Confronting Dogold, Kyoryu Red and Kyoryu Black meet the Deboth Army's newest member: the Resentful Knight Endolf.
Endolf overpowers the assembled Kyoryugers before he and Dogold get into an altercation and are teleported back to the Frozen Castle where Endolf decides to work with Aigaron. Back at the Spirit Base, Yayoi arrives with the new Zyudenchi that she and her grandfather developed to aid Kyoryu Red. However, when Kyoryu Red uses it, he starts acting like Gabutyra.
As Yayoi attempts to find out what happened, Aigaron arrives with Endolf to provoke Ian using Shiro's death. But as the fight goes underway, Aigaron suddenly acts strange during his fight with Kyoryu Black before Kyoryu Red intervenes and then runs off. As the female members give chase on the Deinochasers, the male Kyoryugers fall back with Kyoryu Gold's attack. When the gang regroups with him no where to be found, Torin comes to the conclusion that the new Zyudenchi must have overridden Daigo's mind to believe that he is a dinosaur.
Reluctant of being named temporary leader out of fear of losing his friends, Ian is given courage by Amy before they see Aigaron and Endolf resuming their attack. Learning that Daigo is still there despite the Zyudenchi's influence, Ian's feelings of hatred disappear as he and the other transform to fight the Deboth Knights. While the others fight Endolf, Kyoryu Black battles Aigaron with Kyoryu Pink's aid. But taking Luckyuro's Sukusuku Joyro, Endolf enlarges himself with Plezuon arriving and the Kyoryugers form Plezu-Oh Parasagun to fight the Knight.
Overwhelming Endolf, the Kyoryugers exchange Parasagun for Zakutor so Plezu-Oh Zakutor can deal the final blow. However, the attack fails as Endolf has Luckyuro shrink him so they can fall back. Later, with Ian accepting the temporary leadership position, the Kyoryugers learns of Kyoryu Red's location.
