Zeltrax

Zeltrax was one of Mesogog's henchmen.

Early Life
Terrance "Smitty" Smith was a partner of Tommy Oliver and Anton Mercer during the explosion of their lab where he was brutally damaged. Mesogog found his ruined body and rebuilt him with cybernetic technology into a black armored cyborg.

As Zeltrax
As Zeltrax, he is bent only on gaining revenge on Tommy and holds him responsible for the recent tragic events in his life, including his near fatal accident. During his attempts at revenge, he inadvertently created a clone "son" named Goldenrod. Goldenrod proved a powerful adversary to the Rangers, but was destroyed by Tommy, increasing Zeltrax's hatred of the Black Ranger. After a second near fatal experience, because of his master's plans, Zeltrax mutinied against Mesogog and went out on his own. Zeltrax later gained a super powered form through the special underground spring that flowed beneath the Tree of Life. In the final episode of Dino Thunder, with the aid of the Triptoids, Zeltrax built his giant Zelzord, which was destroyed by the self-destruction of the Rangers' Dinozords. Zeltrax was eventually destroyed by Tommy Oliver and Kira Ford.

SPD Encounter
Zeltrax also appeared in the Dino Thunder/SPD team up episode, Wormhole, which is set before the Dino Rangers' final battles. During the episode, Zeltrax reluctantly joined forces with Emperor Gruumm who had traveled back in time through a temporal wormhole. Together they fought the Dino Rangers and the S.P.D. Rangers. Despite Gruumm's aid, Zeltrax was defeated by a double-team from Tommy and Anubis Cruger, the SPD Shadow Ranger. Zeltrax then retreated and left the Tyrannodrones he had to their doom.
