Hyper Force LogoThis article is about a villain in Power Rangers HyperForce.

"Greetings, enemy of Earth. I know you seek the jewels of the Corona Aurora. I can help you get them if you meet with me."
―Thrax's first words in his message to Flurious and Norg and later to Kamdor and Miratrix.[src]

"Excellent! You are all here! (...) It was I who invited you. Thank you all for coming. I am Thrax."
―Thrax introducing himself to the main villains of Power Rangers Operation Overdrive[src]

"But how?! I took your powers away!"
―Thrax reacting to the newly re-powered Overdrive Rangers before the final battle.[src]

"You again?! I wish I had the sword Excelsior. Then I would use its power to destroy you forever."
―Thrax reacting to the newly arrived Sentinel Knight and his final words before his death.[src]

Thrax was the son of Rita Repulsa and Lord Zedd and the main antagonist of the special two-part team up episode "Once a Ranger". Thrax was the primary antagonist of Power Rangers HyperForce, as the public leader of The Alliance.


Early life[]

The Sentinel Knight imprisoned Thrax into a space dumpster on the Moon. But one day Thrax was strong enough to break the dumpster and free himself.

He is the son of Rita Repulsa and Lord Zedd. He inherited his father's staff, (but it is unknown how he got his father's staff as it was supposed to be destroyed during "Countdown to Destruction" when his father and mother turned good) most of his physical appearance and similar powers. He was also after the Corona Aurora, he was imprisoned by the Sentinel Knight in a space dumpster on the moon just like his mother. As the Knight grew weaker, he grew stronger and escaped from the dumpster. Thrax was angry at his parents for becoming good and wanted to restore their evil legacy.

It is unclear when Thrax was sealed, given that he was done so by an embodied Sentinel Knight, who was only active in such a form thousands of years ago.

Recruiting the Villains[]

Thrax and his Evil Alliance

He recruits the other villains such as Flurious, Moltor, Kamdor, Miratrix and the Fearcats, Mig and Benglo, to defeat the Overdrive Rangers. Though each faction was reluctant at first, they joined together and managed to easily overpower all six Overdrive Rangers, after words they sever the Rangers's link to the Morphing Grid, to keep the Rangers busy, he creates a dragon-like vulture monster called Vulturus.


When the Sentinel Knight restored the power of five veteran Rangers and made them a team, Thrax sought a mystical sword called Excelsior to destroy the knight. However, because of his evil nature, Thrax was unable to claim the sword. He left in a rampage and proved to be a strong fighter overcoming the Defender Vest. In his final hour, he led the four factions into battle with the veteran and Overdrive Rangers. He battled Adam and nearly defeated him. However, he was ultimately destroyed by the reborn Sentinel Knight using the Power Kick Attack. The other villains retreated and broke their alliance to continue their rivalry.


Sometime in the future, Thrax was resurrected by The Alliance using the Corona Aurora. He joins Rita, Zedd and Scorpina in an ultimate attempt to destroy the timeline and get rid of all the Power Rangers teams.


Thrax is similar to his father, Lord Zedd, in terms of personality, as the former is a ruthless, sadistic, callous, vengeful, power-hungry, and coldhearted entity that will do anything in his power to destroy the Power Rangers and rule the Earth. Despite this however, Thrax is highly intelligent (far more than Kamdor) and is very sharp when in battle. However, his obsession with power and vengeance makes him arrogant and rude, as he taunts and makes snide comments over his parent's "betrayal". It can be assumed by his actions that he wished to "avenge" his parents since he was not after the Corona Aurora.

Powers and Abilities[]


  • Monster Creation: Much like Rita and Zedd, Thrax is able to create a monster, such as Vulturus.
  • Teleportation: Thrax can teleport to any location at will.
  • Power Punch: Thrax can charge up white energy into his hand and perform a powered up punch which is strong enough to knock the Black Ranger out of his Defender Vest. 


  • Strength: Thrax possesses far greater strength than any villains in Operation Overdrive, being able to take on the Black Ranger and nearly best him as well as easily smashing his dumpster (after Sentinel Knight weakened) just by thrusting his arms out.


to be added


  • Z-Staff: Being the son of Lord Zedd, Thrax possesses a double bladed staff that bears a resemblance to Lord Zedd's staff which can aid him in combat.
    • Lightning Beam: Thrax can fire powerful white, black, or light blue colored lightning beams from his staff. One blast was strong enough to send the Red Ranger flying.
    • Earth Implosion: By combining his staff's power with all six of the antagonists, he can create an implosion in the Earth. This was his ultimate attack with the other villains and is strong enough to damage the Morphin Grid to such an extent that it obliterated the Rangers' powers.
  • Communication Devices: Thrax used red and white beetle shell-like communication devices, which he can send to an ally.
    • Suction: These devices can even suck people up like a vacuum cleaner. It immediately sucked up Kamdor when she and Miratrix refused his offer. This was used to bring the other villains to him, but its ultimate fate is unknown.

Behind the Scenes[]


  • Thrax is portrayed by Glen Levy in Operation Overdrive. In HyperForce, Thrax is portrayed by Malika Lim, like most other NPCs.


It seems Thrax inherited most of his appearance from his father, due to his physical appearance and his Z-Staff. Also, his powers seem to be similar to those of his father. His mother's appearance isn't apparent, except that he has a part humanoid face, and torn cloth-like orange ornaments wrapped around his horns.

One prominent similarity to his mother is that he too was imprisoned in a space dumpster. His jawbone also resembles that of his uncle, Rito Revolto and has a skeletal spinal column, a combination resembling his father and uncle. Unlike those his father, mother or uncle wear, Thrax possesses shoulder pads and chest armor similar to Zeltrax from Power Rangers Dino Thunder.


to be added


  • Thrax is the first one-time villain to later become a primary antagonist.
  • Throughout HyperForce, Thrax' identity was kept unknown until the penultimate episode.
  • Thrax' communicator resembled the chrome on Lord Zedd's chest.
  • Unlike the other villain factions and even his own parents and grandfather, Thrax is the only one who managed to have a long term victory over the Rangers.
  • The disparity between his adult age, his parents only marrying and considering children for the first time in 1995 and his battle with Sentinel Knight thousands of years ago is unexplained.
  • During the first episode of "Once A Ranger", Thrax says a line similar to Rita's first line of the first episode of the Mighty Morphin' Power Rangers series; Rita's original line was "After ten thousand years, I'm free!" whereas Thrax' line was "After all these years, I'm free!".
  • Some elements of Thrax' body are from villains in other seasons as well as other shows. His shoulder pads and chest armor are from Zeltrax' armor from Dino Thunder. His jawbone is made from his Uncle Rito from Mighty Morphin' Power Rangers. He has a skinless chest similar to his father Lord Zedd and the left side of his looks very much like Grimlord's from VR Troopers.
  • It is unknown how Thrax survived Zordon's Energy Wave. It is possible that Thrax's imprisonment protected him from getting hit.
  • He is the only member of his family that never appeared in Mighty Morphin Power Rangers Season 3.
  • Also on the bottom right of his face looks like a piece of his father's face guard from his helmet.
  • In a 2014 interview, director Koichi Sakamoto stated that the film Kyoryuger vs. Go-Busters, which saw the return of the Zyurangers among the past Kyoryu Super Sentai, was originally to feature a daughter of Witch Bandora. Since Koichi Sakamoto worked on Power Rangers Operation Overdrive as an executive producer, this may not be coincidental. However, this plan fell through for unknown reasons and the character was replaced with Neo-Grifforzer.[1]
  • Thrax is the second villain to have an alliance of past villains and the only one who appears in only two episodes.


Power Rangers: Heroes of the Grid[]

Thrax appears in the board game Power Rangers: Heroes of the Grid as an opponent in the "Villain Pack #3: Legacy of Evil" expansion. He is classified as a Boss.
