The title celebrating 500 episodes worth of Power Rangers

Commemorating 500 episodes, may the power live on forever.

As Mesogog struggles to break into an energy crystal, Zeltrax brings in the captured Tommy Oliver who demands to know what Mesogog wants with him. Mesogog explains that he wants Tommy's help to extract whatever it is that's encased in the crystal, only to Tommy to claim he's just a high school teacher. Mesogog knows that Tommy is behind the sudden appearance of the Power Rangers, and also reasons that he knows what it is in the crystal and demands his help or else he'll use his life-force extractor on him.

At the underground lab, the teens are worried for Tommy's safety after there's been no word from him in over a day. With no other options, Ethan suggests they check out his database for clues... but when they go the console they instead find a video message that was set-up in the case that something should go wrong. Everyone's interest is piqued when Tommy mentions that he is going to chronicle his history as a Power Ranger and begins the story...

When evil space sorceress Rita Repulsa was released from her dumpster prison, Zordon (an intergalactic being of tremendous power) and his robotic assistant Alpha 5 recruited five teenagers with attitude to become the Mighty Morphin' Power Rangers in order to fight her forces and save the world. By harnessing the power of the dinosaurs Jason Lee Scott, Zack Taylor, Billy Cranston, Kimberly Ann Hart and Trini Kwan fought off all her monsters. Eventually, Rita decided to make her own Ranger.

Kira wonders when Tommy turns up, when he suddenly appears on the screen.

Tommy Oliver was the newest kid at Angel Grove High School who was captured by Rita and placed under an evil spell. Transformed into the Green Ranger, he fought against and almost destroyed the Power Rangers but was released from the spell when his Sword of Darkness was destroyed. He then joined the other Rangers in their battle against Rita but the Green Ranger powers turned out to be limited. As a result, Zordon renewed his powers and he rejoined the team as the White Ranger...

Conner, Ethan and Kira are left surprised by their teacher's history as a Power Ranger... but are in for a bigger surprise when Hayley arrives telling them she knows Tommy is in trouble and that they're the only ones who can save him. She reveals that she's been working with Tommy to develop the dino energies and was also responsible for building their morphers. She then shows them security footage of Tommy being captured. Conner asks why Tommy didn't just morph since he's a Power Ranger too, but Hayley explains that he isn't anymore and plays the tape again.

A new villain named Lord Zedd arrived to try and take over the Earth himself. When Jason, Zack and Trini were leaving to attend a Peace Conference, three new Rangers were selected and they passed on their powers to Rocky DeSantos, Adam Park and Aisha Campbell. However the new team were forced to face massive odds when Rita and Zedd teamed up. Later, Rita's brother Rito Revolto arrived and managed to destroy the Rangers' Zords and powers. Never giving up, the Rangers sought out Ninjor and were granted new Ninja powers.

Later, a new girl named Katherine Hillard arrived in town. After proving herself to the Rangers, Kimberly selected her as her replacement when she left Angel Grove to take up gymnastics full-time. Later, Rita and Zedd struck a massive blow when they managed to destroy the Rangers' Command Center. Luckily the Rangers had a new power source with the Zeo Crystal. With their new powers and abilities, Tommy, Adam, Rocky, Katherine and new Yellow Ranger Tanya Sloan became the Power Rangers Zeo and fought against a new enemy; the evil Machine Empire with Zordon, Alpha and a now-retired Billy providing assistance. When the attacks got more and more powerful the Rangers turned to an old friend  and made Jason the Gold Zeo Ranger.

As the Rangers graduated high school and embarked on a new chapter of their lives, they also embarked on a new journey as Power Rangers when they were granted the Turbo Powers to fight against the space pirate Divatox. Soon the team had new powers, new zords and a new Blue Ranger, Justin Stewart. Later, it was decided that Tommy, Adam, Kat and Tanya should be allowed to leave and follow their dreams, and they selected new Rangers to take over; T.J. Johnson, Carlos Vallerte, Ashley Hammond and Cassie Chan had already proven themselves to have what it takes and the four joined Justin to become the new Power Rangers Turbo...

Hayley tells the others that after leaving the Power Rangers, Tommy went to college and met Hayley but knew after finding the Dino Gems he couldn't escape the power for long. Kira suggests they try and find an Invisiportal into Mesogog's lab. Hayley agrees, having been working on that idea and while she tries and finds something she suggests the others keep watching the history of the Power Rangers...

Divatox staged a huge attack on the Rangers's Power Chamber, managing to destroy it and the Turbo Powers forever. She then was recalled into space, and the Rangers decided to follow her leaving Earth and Justin behind. They soon came across the Astro Megaship and an unfamiliar Red Ranger, Andros , who was in the middle of his own fight against the Astronema, the Princess of Evil. Eventually allowing the others to join him and become a team, Andros proved himself to be the perfect leader of the Power Rangers in Space and after releasing the Silver Ranger, Zhane, from his deep sleep they managed to defeat Astronema and destroy all the attacking forces of evil.

However, across space another battle was soon to begin on the planet of Mirinoi. Leo Corbett, Damon Henderson, Kendrix Morgan, Kai Chen and Maya managed to free the Quasar Sabers from their stone to become the Power Rangers Lost Galaxy. The team fought against the evil Trakeena who was bent on destroying the space colony Terra Venture. After a long and hard battle, Leo managed to destroy her with the power of his Battlizer.

Back on Earth, when a group of demons were released from their ancient prison, an elite group called Lightspeed recruited five Rangers to fight back and prevent them from destroying Mariner Bay. Carter Grayson, Joel Rawlings, Chad Lee, Kelsey Winslow and Dana Mitchell stepped up and became the Power Rangers Lightspeed Rescue. After Ryan Mitchell joined the team as the Titanium Ranger, the Rangers managed to defeat the forces of Queen Bansheera.

Hayley pauses the playback as she starts to hack into Mesogog's systems to find an Invisiportal to his lair. Meanwhile, Mesogog tells Tommy his ultimate goal of returning Earth to its prehistoric roots as Tommy wryly asks why he can't just want to take over like all the others. Mesogog demands answers on how to open the crystal, and when Tommy refuses he switches on the life-force extractor.

Back at his lab, the search for an Invisiportal comes up empty. As Hayley prepares to try again, more Power Ranger history starts to play with the section on Time Force. The teens are interested in this, as they could possibly contact them, go back in time and stop Tommy from being kidnapped in the first place.

In the year 3000, Time Force officers Jen Scotts, Lucas Kendall, Katie Walker and Trip traveled back in time in pursuit of escaping mutant criminals who wished to conquer the past. Recruiting Wesley Collins as the Red Ranger, and later being assisted by the headstrong and independent Eric as the Quantum Ranger, the Power Rangers Time Force were able to contain the mutant threat.

Since it's clear that they won't be able to contact Time Force, Conner instead suggests that they team up with all the past Rangers to search for him. Hayley points out to him that not all past Rangers still have their powers... in fact, some Rangers never wanted them in the first place.

In Turtle Cove, the evil Orgs attempted to conquer the Earth through pollution. Cole Evans, Taylor Earhardt, Max Cooper, Danny Delgado and Alyssa Enrilé were all selected one-by-one to become the Power Rangers Wild Force, using powers created by the ancient Wild Zords to fight the threat. They were soon joined by a warrior from the past, Merrick, who became the Lunar Wolf Ranger and managed to put an end to the Orgs once and for all.

The teens are interested in the history, but it isn't any help with finding Tommy. Hayley knows there was one other team of Power Rangers who fought recently, and Conner suggests she look up Ninja Storm as his twin brother was a member of a secret ninja school which selected some students to become Power Rangers. Hayley finds something on them in the system.

When the space ninja Lothor attacked Earth, three failing ninja students named Shane Clarke, Dustin Brooks and Tori Hanson were selected to become the Wind Rangers to fight the threat. They soon found themselves fighting the Thunder Rangers, Blake and Hunter Bradley, who had mistakenly been led to believe that the Wind Rangers were their enemies. Eventually becoming friends and joining forces, the team was later joined by their friend Cameron Watanabe who harnessed the power of the Green Samurai Ranger and completed the team. Using all their abilities, the Power Rangers Ninja Storm were able to defeat Lothor and send him into the Abyss of Evil.

Conner decides to show off some ninja moves his brother taught him, but ends up kicking the computer equipment instead. At first it seems like all hope of finding Tommy is lost, but instead the jolt causes the system to start to find a way to him. At this point, the final part of Power Rangers history comes up...

Tommy explains that now Mesogog has returned, he has recruited Conner, Kira and Ethan to become the Power Rangers Dino Thunder. He ends the tape stating that if something happens to him then the Earth is in good hands.

Conner, Kira and Ethan are amazed at the trust that Tommy shows in them and resolve to save him, knowing the whole world owes him for all he and the past Power Rangers have done to protect them. At this point, Hayley finds an Invisiportal to Mesogog's lair. The Rangers get ready to leave and save their teacher.

In Mesogog's lab, Tommy strugges as the life-force extractor continues to drain him...




  • When Ethan panically exits out of the video tab after hearing Hayley's voice, the paused video is seen. However when the camera pans over to Hayley and back to the trio, the paused video is gone.
  • When describing Eric Myer’s character arc, Tommy says "It took a while for Eric to learn that the greatest virtue of being a Ranger is not the power, but the reward of helping mankind." This is despite the fact that Eric’s selfish motivations was never for power, it was to show up Wes who he saw as a spoilt rich boy who never had to fight for anything in his life.


  • The episode begins with the following caption: "Commemorating 500 episodes, may the power live on forever."
  • This episode is similar to the first episode of Kousoku Sentai Turboranger, Counting on You! Turboranger, which is a clipshow giving an overview of the previous Super Sentai series.
  • Conner, Ethan, and Kira do not appear morphed during this episode.
  • It is revealed at the beginning of this episode that Ethan knows how to hack computers, something alluded to in Day of the Dino when he rigs the sprinklers to go off at random intervals.
  • Conner claims to have had a twin brother who went to a "secret ninja school," saying that everyone there knew that a few students became Rangers. This was a reference to the 2-part finale episode of Ninja Storm, as one of the new students, Eric, was played by James Napier himself.
    • This is the third time a new member of the current Rangers has had knowledge of another team of Rangers. The first being Leo who knew Andros from the invasion of Earth, and the second is Carter & Kelsey who were familiar with the Galaxy Rangers.
  • Hayley reveals that she and Tommy have known each other since graduate school and that she also knows Cam personally, considering him even better with technology than her.
  • Conner acknowledges that there must be hundreds of Rangers in existence, but Hayley states that most don't have their powers anymore. However, this statement is false as only about half the Rangers before Dino Thunder lost their powers: Mighty Morphin', Turbo, Wild Force, Ninja Storm. The rest until that point: Zeo, In Space, Lost Galaxy, Lightspeed Rescue, and Time Force still do.
    • This somehow became untrue when every known Power Ranger fought in the Legendary Battle.
  • The fullscreen aspect ratio version of the Turbo: A Power Rangers Movie is used for the clip show.

Tommy's Video

  • Joel and Cole are only seen in their morphed forms.
  • This was the first onscreen naming of the Space Ranger's Astro Morphers.
  • It's unknown how Tommy has footage of these events.
  • Tommy mistakenly calls the Quasar Sabers the Galaxy Sabers.
  • It's unknown how Tommy knows about the events of seasons that happened after Passing the Torch. However, as he joined up with several other Red Rangers in Forever Red, he may have listened to the stories of each of the Red Rangers and their teams.
  • At the beginning of the diary, Tommy states that Kimberly Ann Hart, Trini, Billy, Zack, and Jason were the Earth's first Power Rangers. However, this has been proven to be untrue, as the Ancient Samurai Rangers battled the original wave of Nighlok in the 12th century, Sir Ivan of Zandar became the Gold Dino Charge Ranger in the 13th century, and the Morphin Masters were responsible for creating the first team of Dino Fury Rangers. However show wise, Tommy may not have known about them, and obviously they did not exist production-wise when this episode was made. The Wild West Rangers also briefly had powers, though they were very short-lived.
  • Tommy claims that his friends were able to destroy the Power Sword to free him from Rita's spell, but the weapon's proper name was the Sword of Darkness. This is a repeat of Zack making the very same goof when the event actually happened.
  • Tommy claims that upon joining the team, he soon discovered that the Green Ranger powers were only temporary. They only became temporary when the Green Candle took affect on them and he had to temporarily give them to Jason before reclaiming them for a while.
  • The sections regarding each Power Ranger team and their respective missions become shorter and less detailed as they become more recent. This possibly reflects Tommy's lack of personal knowledge of those teams or simply time constraints on the episode's content. As such, the Space Rangers are the final team in which Tommy mentions every Ranger by name, though he named most of the Galaxy Rangers. For Lightspeed Rescue, Time Force and Ninja Storm only the Sixth Rangers (Ryan, Eric, and Cam respectively) are mentioned by name. Similarly for Wild Force, Tommy only names Cole and Merrick.
  • Conner mentioned that Tommy was the oldest living Ranger, which isn't true even at that time because of Merrick who is over 3,000 years old, Ivan, who is 800 years old, Koda, while being much older at 100,000 years old, did not become a Ranger until the present day, and Zayto, who is 65,000,000 years old, but the latter three did not exist production-wise when this episode was made.
  • Tommy makes no mention of many prominent villains throughout the show's history. The Machine Empire is only represented by Cogs featured in previous footage and King Mondo, Queen Machina and Prince Sprocket are neither seen nor mentioned. Scorpius is not seen or mentioned despite being the main enemy of the Galaxy Rangers for the first half of the season. Similarly, Trakeena is not seen in her base form only when she merged with Deviot and her final green bug form. No villains for Lightspeed Rescue, Time Force or Wild Force are seen or mentioned by name at all, simply referred to as demons, a mutant criminal and Orgs in general. Lord Zedd is also featured very little despite being the sole enemy to the Rangers once Rita left and Serpentera is seen but not mentioned directly.
  • A number of events/characters are not featured in Tommy's video diary (presumably due to episode's time constraints):
