When Lord Zedd arrives and overruns Rita, he sends his new brand of Putty Patrollers to Earth. The Putties possess superior strength to Rita's Putties, but it is Jason who discovers their weak spot. To compete with their new enemy's more powerful monsters, the Dinozords are upgraded into the mythical Thunderzords; Jason's Dinozord becomes the Red Dragon Thunderzord, which can transform into a humanoid form. As with the Tyrannosaurus, the Red Dragon can defeat a monster on its own, separate from the Megazord formation.
