Anton Mercer continues to struggle against Mesogog, as he turns one of his projects into the Jade Gladiator. As an inbalance increases in the Morphing Grid, the two White Rangers must finally do battle. Can the Power Rangers stop this new monster? And which White Ranger will win in an ultimate showdown?
When Trent goes to visit Anton, Cassidy and Devin come to get an interview. Trent escorts them out when Anton begins to feel sick. Meanwhile, the evil White Ranger clone's powers begin to fluctuate. Elsa explains that only one White Ranger can exist and one must go. Anton transforms into Mesogog, who while trashing his lab finds a rare plant, which he can use for his evil purposes. Ethan gets a message from the evil White Ranger clone on his laptop challenging the Rangers to battle. Four of the Rangers show up to deal with the White Ranger clone. The White Ranger clone calls to take the battle to the Dinoords, so the Dino Stegazord and Triceramax Megazord engage in battle. Trent returns to Anton's lab, when he begins to experience a painful power surge as well. The White Ranger clone's powers weaken and he loses control of his Dinozords. Mesogog uses the plant from Mercer's lab to create the Jade Gladiator. Hayley explains that the White Ranger's Dino Gem power can only be obtained by one White Ranger. Meanwhile, the energy is fluctuating back and forth. The Rangers are alerted to the Jade Gladiator's attack and morph into action. Trent is heading back to the Dino Lab, when he is confronted by the evil White Ranger clone. Trent morphs into the White Ranger, "White Ranger, Dino Power!" Both White Rangers fight in a battle to the death. The Jade Gladiator gives birth to a new Deadwood and a new monster named Skortch. The Black Ranger gets control of the Dino Stegazord. The Dino Stegazord uses the Ankylozord and Parasaurzord to help destroy the monsters. Trent is victorious and finally destroys the evil White Ranger clone once and for all. Trent joins the other Rangers as they morph into action, "Dino Thunder, Power Up!" The Power Rangers combine the Thundersaurus Megazord, the Dino Stegazord, and the Mezodon Megazord in order to create the Valkasaurus Megazord. The five Rangers unite together in the cockpit ready to go into action. The Valkasaurus Megazord surfs down the Brachiozord. The Valkasaurus Megazord uses the hatchet attack to destroy the Jade Gladiator. The Valkasaurus Megazord poses victoriously. Later, Elsa realizes that Mesogog won't accept her failures any longer. Her only chance would be to strike when he's most vulnerable. Anton shows up to congratulate Trent for all the good he's done. Trent only hopes Anton will find a way to get rid of Mesogog soon.
