The Dairanger storm into the Gorma Palace in order to take down their eternal enemy, unknowing of the horrifying extent of Shadam's control of events!
Kaku dies and turns into glittering lights that flies away. The five mourn him and Ryo swears to defeat the Gorma once and for all. The five of them gear up and they transform. They call their Mythical Chi Beasts, mount them and fly to the Gorma Palace. Inside the palace, the Gorma applaud Shaddam. He makes a speech. Gara runs in with news about Zaidosu becoming clay and dying. Shaddam just laughs at her. Everyone keeps saluting him and she is clearly disturbed. They then hear the Dairanger invading and all of them run from the Great Hall. The Dairanger are fighting red Cotpotro. The Gorma confront them. The Dairanger threaten the Gorma and the other gorma run off scared. Shaddam calls for more Cotpotro and two silver warriors. Metal Faced Jiaxu and Zilong, who resemble the armors of Kaku and Shiryuu Chuui. The Dairanger fight them. Shaddam and Gara then decide to join the battle. Daigo calls Gara out because of her vendetta aganist Kujaku. Lin goes after Daigo. Gara jump out of the palace and Daigo and Lin follow her. They meet up outside. Daigo recalls the events of episode 41 when Kujaku cured Gara's scars. Shaddam runs to the door and disappears, without opening it. Ryo approaches the door. When he touches it, it lights up. It explodes, pushing him up. Shaddam talks to the Emperor, telling him of the Dairangers arrival. He wants the Earth Shaking Jewel but the old Emperor refuses. The Emperor brings out the large red crystal. He blasts Shaddam with its power. Shaddam falls to the floor. The Emperor laughs and hits Shaddam again with the power. Meanwhile, Gara wraps a lasso around Daigo and drags him on the ground, in a circle around her. She throws him down a cliff and he jumps back up but she swings him over her. Lin protects him as he recovers. Emperor blasts Shaddam again. Shaddam brings his left hand up in the air towards the old crazy man. Emperor XV's third eye rolls back and he becomes clay. His hand crumbles and the jewel falls into Shaddam's hand. It happens the Emperor was only a clay copy. The Emperor screams as he crumbles and Shaddam laughs at his accomplishment. Only the Emperor's head is left. Kazu throws a Dairinken on one of the soliders and Shouji kicks his head in. He disappears. Ryo comes in and destroys the other one with his fire attack. Ryo tells them to call their powers to open the door Shaddam has locked. It blows up and they enter the Emperor's room. In the chamber, the three see the Emperor's head crumble. Shaddam laughs and their attention is directed to him, he is already standing on a collumn high up. Gara laughs because she is winning against Lin and Daigo. She goes after them again. Daigo does his illusion attack. Lin does her wind attack and knocks Gara down. Daigo is about to do Gara in when... Then his peacock feather falls and glows. It flies away and the two Dairanger follow it. Daigo and Lin are taken out of armor by the energy. Kujaku appears on a high point of rocks. She calls for the 'real' Gara. Daigo is shocked and so is the Gara we have grown to know. Kujaku explains that the Gara they had been fighting was a fake so the real Gara has been dead all this time and in heaven. Heavenly Gara moves her hand and evil Gara screams and turns to clay, breaking apart. Lin shields her eyes as there is just a head. The real Gara calls for it to disappear. Daigo looks back at Kujaku, she and the real Gara hold hands and leave to the Heavens, not before Kujaku bids him farewell. Inside the palace, Shaddam uses the power of the jewel and becomes the new Emperor. Shaddam laughs much like the last Emperor. He blasts at Ryo, Shouji and Kazu. The three circle around the new Emperor and gives them a blow using the crystal. His sanity slowly breaks down and he tortures Ryo, knocking him around everywhere. Just then the Earth quakes. Daigo and Lin gasp as Daijinryuu has returned. This time, Daijinryuu is directly attacking the palace. The humanoid Gorma scramble around as the palace deteriorates. Daigo and Lin fear for the safety of their friends. Kameo and Kou arrive and join Lin and Daigo. A hole breaks from the ceiling of the palace and Dairinjyuu's energy starts entering, causing fires inside. Shaddam curses the Dairanger and flies up and attacks the three men. Fire raises high in the air as Shaddam laughs. Daigo looks at the palace angrily.
