12x13 White Thunder, Part III

The White Ranger steals the Rangers' Stego Zord and combines it with his Drago Zord to form the Dino Stegozord, which promptly blasts the Thundersarus Megazord apart. While a trio of auxiliary Zords are sent into battle, Conner dukes it out with the White Ranger and unlocks his Super Dino Mode in the process. Later, Tommy discovers the White Ranger's true identity as Trent, but is encased in amber before he can tell the others.
