"Power Rangers: Defenders of Earth!"
―Rangers announcing their arrival.

Wormhole is the thirty-fifth episode of Power Rangers S.P.D., serving as the second crossover with Power Rangers Dino Thunder.


Gruumm travels into the past and recruits Zeltrax in his plan to conquer the Earth before the formation of S.P.D.. The S.P.D. Rangers must follow him and teamup with the Dino Rangers in order to stop them before the wormhole closes and they're trapped in the past.


Emperor Gruumm is confronted by Omni over why the Rangers constantly manage to defeat him. To achieve victory, Gruumm takes the Terror through a wormhole 21 years into the past.

Kat alerts the Rangers of Gruumm's temporal trip into the wormhole.

At Reefside High, in 2004 - Conner, Ethan, Kira, and Trent witness the Terror hovering over the school. Gruumm intends to take over the Earth without interference from S.P.D..

Commander Cruger sends Jack, Bridge, and Z on a mission to follow Gruumm through the wormhole.

The Dino Rangers go into the woods in search of the Terror. Rather than finding the Terror, they are confronted by Zeltrax and the Tyrannodrones. Jack, Bridge, and Z travel into the wormhole in search of Gruumm. As the Dino Rangers fight Zeltrax, the Terror appears and beam him aboard.

Gruumm tortures Zeltrax and demands that he helps them defeat the Power Rangers. Zeltrax assures him that it would be his pleasure. Jack, Z, and Bridge reintroduce themselves and inform the Dino Rangers of Gruumm's plans.

Meanwhile as the wormhole closes, the other S.P.D. Rangers prepare to join up with the others before the others are trapped in the past.

Meanwhile, Tommy appears as the Black Ranger in a battle against Zeltrax, who leads an army of three monsters created by Mora, all three levels of Krybots, and the Tyrannodrones. The Dino Rangers teamup with the S.P.D. Rangers to fight Zeltrax's Army. Gruumm and Mora watch as the rest of the S.P.D. Rangers show up to help their comrades. Tommy and Doggie meet for the first time and lead the Rangers against their opponents.

Kira, Syd, and Z team up to defeat the Spotty-Eyed Monster while Sam and Trent work together to destroy the Foot Soldiers. Bridge, Ethan, and Sky take down the Green Monster as the Black Rangers, Tommy and Cruger, defeat Zeltrax just before he retreats. Jack and Conner both activate their Battlizers to take out the Vine Monster.

On the Terror, Gruumm angrily decides to join the fight and finish the Rangers off himself but Mora informs him that the wormhole is closing and if they don't go back to their own time, they're never going back. However, Gruumm decides to conquer Earth right now, but Mora also reminds him that he'll have to reconquer all the galaxies and planets Gruumm already defeated since they're in the year 2004, that has yet to happen. Gruumm reluctantly agrees with Mora and set the Terror ship back on course to return to the future.

Meanwhile back on Earth, the Power Rangers assemble the Z-Rex Blaster and the Canine Cannon to finish off the Foot Soldiers.

Before the S.P.D. Rangers return to the future, Doggie erases their and the Dino Rangers' memories. Gruumm states to Omni that he underestimated the Rangers and assures him that it won't happen again. He then agrees to prepare for Omni's arrival.

Continuity and Placement[]



  • Bridge explains to the Dino Rangers' that their memories were erased during the events of their previous encounter, but timeline-wise the event would not occur for the Dino Rangers for at least another year.
  • Trent's morphing call is the default "Dino Thunder, Power Up" instead of his unique "White Ranger, Dino Power".
  • When Conner calls out ready to Ethan, Kira, and Trent to morph, the four of them have their Dino Morphers already on their wrists, but in the next shot, Conner has his Dino Gem turn into the Morpher.


  • Although Anubis 'Doggie' Cruger erases the memories of himself and the other Rangers, Tommy and Sam aren't present and remain with their memories intact. And then the Dino Thunder teenagers saw the S.P.D. team anyway, all the students of Reefside High still remember the Terror Spacecraft and Zeltrax would also have his memories intact.
  • This episode was aired early in Canada before being realized as an exclusive DVD episode for S.P.D..
  • This would be the last classic-style team-up episode, including all core and sixth Rangers from two different teams, until the Power Rangers Beast Morphers' "Finders Keepers".
  • Tommy does not appear unmorphed in the episode due to Jason David Frank being absent from filming, while his morphed lines are voiced by Jeffrey Parazzo. Frank stated that he was not offered to return due to Disney not willing to pay to fly him over to New Zealand.
  • The first Orange-Head Krybot Jack fights uses orange painted Chrono Sabers, from Power Rangers Time Force. In fairness, the Igaroid in episode 30 of Dekaranger uses orange painted Double Vectors.
  • When the Rangers are outnumbered by Zeltrax's army, Cruger quotes Mark Twain: "It is not the size of the dog in the fight; it's the size of the fight in the dog".
  • This episode marks the final unmorphed appearances of Conner and Ethan. They would appear again morphed in "Legendary Battle" & "Grid Connection".
  • This also marks the final unmorphed appearance of Trent until the episode "Dimensions in Danger".
  • Tommy would later appear unmorphed as the Mighty Morphin Green Ranger in "Legendary Battle".
  • This is the last episode where the S.P.D. Battlizer is used.
  • Gruumm traveling into the distant past to conquer Earth before S.P.D. existed is similar to Ransik traveling one thousand years to the past to take over Silver Hills without any interference of Time Force and both of them were followed by their respective Rangers.
  • Despite being the thirty-fifth episode of S.P.D., the official Power Rangers YouTube channel lists this episode as Episode 32.
