It's a Mad Mad Mackerel
Zeltrax, desiring to atone for his loss to the White Ranger and win back Mesogog's approval, creates Copyotter, who uses his special ability to copy the Rangers' weapons and use it against them. He creates a duplicate of the White Drago Sword, which Zeltrax use to frame Trent in trashing Mesogog's lab. Mesogog tries to destroy Trent with the Lifeforce Extractor for his betrayal, however he suddenly transforms back into Mercer and the extractor released the gem of its evil influence allowing Trent full control over the power. Finally in control he helps the other rangers defeat Copyotter and re-earns their trust. By the end of the day, Zeltrax creates an evil White Ranger clone. The story of how Mesogog was born, as told by Anton Mercer himself.
Kira and Conner were at Hayley's Cyberspace. Kira was surprised to see Ethan was waiting on tables. Ethan had decided to help Hayley out since Trent quit. Conner and Ethan launched into a conversation about Trent, with Conner commented that Trent had been keeping busy kicking their butts and Kira had to admit that maybe the guys were right. Kira thought that maybe there wasn't any good left in Trent.
Trent was practicing his battle skills with several Tyrannodrones. Trent made quick work of the Tyrannodrones. The Tyrannodrones were simply too easy. Trent told his father, who had walked out, that he needed some thing a bit more difficult. Trent sat in a chair and looked at this dino gem bracelet. His father sat down too. Trent continues to grow stronger with the power of the White Dino Gem, but Anton Mercer doesn't approve with the path he has taken. Anton reveals that he was on the verge of what he thought was breakthrough, when he accidentally transformed himself into Mesogog since he felt the experiments were too dangerous to conduct on anyone else, and so he did them on himself. Trent thought that they were on the verge of bringing back the dinosaur era and that was what his dad wanted. Dr. Mercer told his son it was what Mesogog wanted, not him. Dr. Mercer stressed to his son that this wasn't the life he wanted for his son. Trent angrily replied that it was a little too late for that and angrily left his father. Dr. Mercer is left to ponder the consequences of his experiment on himself.
Meanwhile, Elsa laughs at Zeltrax for his recent failure against the White Ranger, but Zeltrax swears that he will get revenge. Zeltrax uses the Geno Randomizer to create the Coppyotter. Tommy summons the other Rangers to deal with the Coppyotter, who has attacked a warehouse. Copyotter has the ability to copy things, and begins by copying the Rangers attacks, weapons and even their voices. He also runs into Cassidy and makes three extra copies of her, although He tells himself that he'll probably regret it later.
Trent catches up with Zeltrax's creation. He thinks that maybe Copyotter might provide more of a challenge and they battle. He also makes a copy of the White Ranger's Drago Sword, which Zeltrax shows to Mesogog in his trashed lab. The Power Rangers engage the Copyotter again and Connor Suggests they close the head of the Tyranno staff when using the Z-Rex Blaster as The monster will make a copy, and when Copyotter fires it the copy will explode. Unfortunately, Copyotter notices the closed head on the Z-Rex Blaster copy and opens it, along him to use it against the rangers. Trent watches and plans to take on the winner, when he is pulled through an invisiportal by Mesogog. The Black Ranger comes to help out the other Rangers.
Mesogog had him strapped to a reclining chair and adjusted a few instruments on the Lifeforce Extractor. Trent didn't understand why Mesogog was calling him a traitor and tells him that he has the wrong guy. Mesogog wouldn't listen. Mesogog prepared the equipment to eliminate Trent. A beam of light surrounded Trent and he could feel his life ebbing away. Desperately, Trent called out to his dad, reminding him that he was his son. Trent begged his father not to do this. Anton comes to Trent's rescue just in time to save him and in the process the laser shatters the evil encoding over the Dino Gem. Anton tells Trent to go use his powers for something good and help the other Rangers. Dr. Mercer almost collapses and tells Trent that he knows Trent will do what he has to do. Dr. Mercer vows to find a way out of the mind sharing with Mesogog. Trent promises his father that he won't tell anyone his secret.
Trent morphs into the White Ranger and activates Super Dino Mode. The White Ranger uses Super Dino Mode to destroy the Copyotter. As the Rangers battle in the Zords, Zeltrax catches Tommy off guard. The White Ranger comes to his rescue and takes on Zeltrax. The Black and White Rangers teamup to take down Zeltrax together. Tommy wants to know why Trent helped him, and Trent tries to tell him. Meanwhile, the Thundersaurus Megazord takes down the Coppyotter for good.
When the Rangers return to the Dino Lab, they find that Trent is there, and he wants to join them. Tommy says that he believes Trent wants to help. The other Rangers are hesitant, but decide to give Trent one last chance. The other Rangers play on Trent's new arrival into the team and tell him that he has to wash all the Zords. Meanwhile, Zeltrax reveals that he used the Coppyotter's power to create an evil clone of the White Ranger, one without any trace of Trent Mercer.
- From this episode onward, Trent switches to the side of good.
