Watch Power Rangers online: Episode 21 Copy That

Anton Mercer relays the story of how Mesogog was born, out of testing an advancement in dinosaur DNA on himself, to his son, Trent. Zeltrax, desiring to atone for his loss to the White Ranger, creates a bell pepper-based monster, Copyotter. As his name implies, he has the ability to copy items and people. He copies the Rangers' weapons and uses them on the heroes. He creates three clones of Cassidy, sending poor Devin into near insanity. And most importantly, he creates a duplicate White Drago Sword, with which Zeltrax frames White Ranger in trashing Mesogog's lab. Mesogog uses the Lifeforce Extractor (from "Legacy of Power" and "Back In Black") on Trent for his betrayal. But appealing to his father within, he's able to urge Anton out of Mesogog just in time. When freeing his son from the machine, a stray beam strikes the White Dino Gem, negating the evil code implanted within, thus freeing Trent from its control. Trent, now in control as the White Ranger, saves Dr. Oliver from an attack by Zeltrax, choosing to fight for the side of good. He joins the DinoThunder team, hoping to make up for the bad deeds he took part in. Copyotter is destroyed, but Zeltrax, retaining its copying device-arm, creates a Trent-less, entirely evil clone of the White Ranger, loyal only to Mesogog and his wicked forces.
