Zeltrax

"You didn't think I'd let you go that easily. You're going down Tommy."

- Zeltrax confronting Tommy and Kira whilst the Megazords fought the Zelzord and his final words before his death.

Zeltrax, previously known as Terrance "Smitty" Smith, was one of Mesogog's henchmen. He is the tertiary antagonist of Power Rangers Dino Thunder.

Early Life
Terrance "Smitty" Smith was once a partner of Tommy Oliver and Anton Mercer. At some point, Tommy and Smitty were up for the same job, and Mercer chose Tommy over Smitty. Smitty went to work for a different company, where, during an explosion at his lab, he was grievously injured. 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, Zeltrax kidnaps Elsa (who was reverted to a normal human being after her powers were sacrificed by Mesogog to power his trans-mutation cannon) and invades the Rangers' base. Then, with the aid of the Triptoids, Zeltrax built his giant Zelzord, where Elsa is held hostage. Zeltrax uses his Zelzord to demolish Reefside, but Tommy battles Zeltrax along with Kira who rescues Elsa just in time before the Zelzord is finally obliterated by the self-destruction of the Rangers' Dinozords. Elsa is saved, and Zeltrax was eventually destroyed by Tommy and Kira.

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.

BSA-Cursed_Armor.jpgs and abilities.

 * Super Strength-As one of the main antagonists of Dino Thunder, Zeltrax was incredibly strong. He is surpassed in strength only by Messogog himself (it is unknown whether Elsa has more physical strength than him). When fighting the Rangers during thier first battle, whilst using his tractor beam ability, he was able to pick up  and throw around Ethan by simply swinging around him hand. When Tommy hit Elsa, he was shown to be able to shove Tommy hard enough to knock him back several feet back.
 * Durability-As a human rebuilt into a robotic suit, Zeltrax was immune to most attacks from the Rangers. He was able to be balsted by the Z Rex Blaster finisher, and then subsequently explode because of it, and was only sent flying. When his Aerial Assault Craft began detonating around him, all he had to do was shield his face from the explosions to be unhurt. When defending the island fortress with Elsa and Pollinator, he was able to be jabbed in the torso by Connor's sword arm and only stumble back. Whilst fighting Connor in the fourth episode, when he tried to keep the Rangers from entering the Island Fortress to rescue Tommy, he took a massive kick to his torso which subsequently knocked him down but only briefly stunned him.
 * Mental Resistance-Despite having presumably endured many mental torture sessions from Messogog, both on and off-screen, Zeltrax was never worse off for it.
 * Resiliance-After being blasted by the Z Rex Blaster, he was able to get right back up again.
 * Tyrannodrone Summoning-Zeltrax can summon Tyrannodrones to assist him in combat.
 * Tractor Beam Projection-Zeltra can fire blue energy from his palm that will wrap around his enemy and allow him to lift them into the air.
 * Helmet Blasts-Zeltra can fire purple energy blasts from the sides of his helmet/robotic head. These were powerful to knock the main three Rangers down in a single hit.
 * Portal Summoning-Zeltrax can summon portals to step into in order to make a fast getaway.
 * Teleportation-Zeltrax can teleport to any location at will. He was able to do this fast enough to escape his exploding Aerial Assault Craft.

Arsenal.

 * Sword-Zeltrax uses a sword to aid him in combat and is his main offensive weapon.
 * Blue Energy Streams-Zeltrax can fire streams of blue energy from his sword. These could cause large explosions.
 * Shield-Zeltrax has an almost industructable shield to protect him whilst in combat. It was powerful enough to block a full force roundhouse kick from Tommy as well as a glasncing blow from Elsa's blade without damage.

Powere and abilities.

 * Enhanced Strength-As it's name suggests, Zeltrax's ultimate form is far more powerful than his ordinary form but is still seemingly outmatched by Messogo in terms of power.
 * Enhanced Durabillity-Much like his strength, Zeltrax's durability was also enhanced tenfold by his ultimate form.

Arsenal.

 * Sword-Zeltrax retains his sword to aid him in combat and is his offensive weapon.
 * Shield-Zeltrax retains his shield to protect him whilst in combat.
