Conner McKnight / Red Tyranno Ranger | (Actor: James Napier)

Dude. "Computer club"?

Ethan James / Blue Tricera Ranger | (Actor: Kevin Duhaney)

An invisible science teacher. That is so totally graphic novel!

Kira Ford / Yellow Ptera Ranger | (Actress: Emma Lahana)

Did you just call me 'babe'? Did he just call me 'babe'?

Dr. Tommy Oliver / Black Brachio Ranger | (Actor: Jason David Frank)

Note: See also the character sheets for Mighty Morphin, Zeo, and Turbo.

I may be old, but I can still pull it off.

  • The Ace: This is our first Sixth Ranger after all.
  • Adaptational Badass: His Abaranger counterpart is badass, but he's not a Living Legend like Tommy.
  • Adventurer Archaeologist: He's a doctor in archaeology and an experienced Power Ranger.
  • And Starring: Jason David Frank is the last to be credited, but is featured with this.
  • Badass Beard: He's grown a pretty cool looking patch of stubble on his chin since we last saw him.
  • Badass Bookworm: Managed to earn a PHD since graduating, and still kicks as much bad-guy butt as before.
  • Badass in Distress: In some episodes.
  • Badass Teacher: Science teacher at Reefside High.
  • Big Good: Mentor to the team.
  • The Big Guy: The most experienced fighter.
  • Broken Ace: If the events of "Fighting Spirit" are any indication.
  • The Bus Came Back: His last appearance as main character before this series is Power Rangers Turbo.
  • Cerebus Retcon: You know all that dark stuff that happened to Tommy in the first five seasons? It all comes crashing down. "Fighting Spirit" in particular lends itself to this.
  • Composite Character: This is Tommy's fifth Ranger identity.
  • Cool Teacher: He's a school teacher, and a Power Ranger.
  • Dark Is Not Evil: The Black Ranger.
  • Deadpan Snarker: "We can talk about your Dino Easter Egg theory..."
  • Four Is Death: He's the fourth Ranger on the team and is wearing his fourth color overall. Over the course of the series, he gets frozen in amber, hit with two different instances of Power Incontinence, and is briefly put in a coma.
  • He's Back: Happens twice, when he morphs for the first time, and later when he recovers from being in a coma with access to Super Dino Mode.
  • Hot Scientist: A male version.
  • Hot Teacher: If you like older guys.
  • Invisibility: His civilian power. Was even stuck like this for two eps.
  • I Was Quite a Fashion Victim: To his defense, long hair was cool back in the 90s!
  • Living Legend: His reputation has surpassed Jason's, due to having been four colors (green, white, red, and black), and having been leader of three teams of rangers. Both in and out-of-universe, he is considered the "Greatest Ranger Ever" and for good reason.
  • Mentor Archetype
  • Older and Wiser: Compared to the Mighty Morphin to Zeo days.
  • Power Incontinence: Twice; the first time, he got stuck in his morphed form by the White Drago Ranger, and the other time, he got stuck in his invisible form.
  • Retired Badass: At first, though it's not long before he takes up a morpher once more.
  • Same Character, but Different: Entirely justified considering it has been six seasons since the last time we saw him (not counting Forever Red, where he was more or less similar to how he is in this show).
  • Seen It All: Tends to give off this vibe at times. Then again, he is considered by many to be the greatest Ranger in history for a reason.
  • Stern Teacher: Especially when compared to Randall, who is literally an enemy.
  • Still Got It: Though it's not like he ever lost it.
  • Supporting Leader: He's a veteran Ranger, but Conner's still the actual leader of the team.

Trent Fernandez-Mercer / White Drago Ranger | (Actor: Jeffrey Parazzo)

I know I've got a lot to make up for, but I promise - this time, I won't let you down.

  • Adaptational Heroism: Played with. AbareKiller was villainous of his own volition, and while he did eventually also reform and join the team, it was at the tail end of the series. This facilitated the use of the clone, as stated below, only killed off when the show reached the footage corresponding to AbareKiller's Heel–Face Turn.
  • Ascended Fanboy: He gets to meet a comic book artist he admires and the two even work on a comic together after Trent is forced to tell him he's the White Ranger (Anton bankrolls it without telling him).
  • Because You Were Nice to Me: Despite their differences, Trent has a strong attachment and an Undying Loyalty towards Anton because he adopted him and was the only one to care after he was orphaned. It comes to backfire him horribly after his teammates find out that Anton is Mesogog and Trent has been covering it all along.
  • Brainwashed and Crazy: He gets better, though.
  • Card-Carrying Villain: His White Ranger persona was this at first:
    "I am evil, you are good. It's a quite simple concept."
  • Cloning Blues/Evil Twin: Because Abarekiller is villainous for the majority of Abaranger, Trent was given an evil clone so that they could use more of the stock footage.
  • Cool Sword: It shoots energy arrows!
  • Deadpan Snarker: His White Ranger persona.
  • Decomposite Character: Because he pulled a Heel–Face Turn quite early compared to his Abaranger counterpart who is the 11th Hour Ranger, a White ranger clone was made to complement the source footage.
  • Evil Sounds Deep: When brainwashed. His clone also has the abnormally low voice.
  • Full-Name Basis: His clone refers to him as "Trent Mercer." Trent's surname is actually inconsistent, as Elsa (as Randall) calls him Trent Fernandez.
  • Happily Adopted: Dr. Mercer took Trent in after his biological parents died at an archaeological dig. Their relationship may be strained most of the season, because of Mesogog, but they clearly care about each other and Trent still has no problem calling him "Dad".
  • Heel–Face Turn: Starts off being evil (against his will); ultimately turns back to the side of good.
  • Invisibility: His Dino Gem grants him a chameleon-esque form of camouflage.
  • Light Is Not Good: Despite being white, his Gem started out as made of "pure evil."
  • Light Is Good: He eventually breaks free of the gem's influence, and joins the side of the other rangers.
  • Lonely Rich Kid: At the beginning.
  • Manipulative Bastard: Tries to play both the Rangers and Mesogog's crew for suckers when evil. Doesn't work out well.
  • Morality Pet: To Anton.
  • My Father, Right or Wrong: He and Anton have their differences (in no small part due to Anton being manipulated by Mesogog), but he remains loyal to his father.
  • Not So Different: From Tommy. Trent is a Ranger with a chest shield and a dragon Zord who starts out evil due to being Brainwashed and Crazy but then joins the team he once fought against.
  • Parental Abandonment: Both his parents died in an accident, so Anton effectively adopted him.
  • Ship Tease: Has some of this with Kira. However, it isn't as significant, due to the series being more about Trent and his father's relationship instead. By the finale they end up as Just Friends.
  • Sixth Ranger: Fifth to be exact.
  • Smug Smiler: When evil.
  • Spared by the Adaptation: AbareKiller wound up performing a Heroic Sacrifice near the end of Abaranger. Trent, however, survives the series.
  • Split-Personality Takeover: The white Dino Gem initially performs a Grand Theft Me and forces Trent to morph and act as a vehicle for the powers. Despite Trent's best efforts, the gem's influence slowly overtakes him and the personalities merge. This is completely undone when the dino gem's evil encoding is broken.
  • Super-Powered Evil Side: The White Ranger at first, who gradually takes more and more control over him until he's finally freed and can utilize his powers.
  • Unknown Rival: To Conner and Zeltrax.
  • "Well Done, Son!" Guy: Not that he ever admits it. Thanks to some Character Development, he grows out of it in the end.


Mesogog/ Anton Mercer | (Actor: Latham Gaines)

  • Agony Beam / Mind Rape: His preferred method of keeping his minions in line (he uses it on them more than his actual enemies). The one time he tries to use these powers on the Rangers, his subordinates accidentally teleport in front of him and get hit by the blast instead.
  • Badass Longcoat: He wears one.
  • Bad Boss: He doesn't take failure lightly and will gladly Mind Rape his henchmen to remind them so.
    • There is one instance in Thunder Storm Part II in which he seemingly shows a tiny sliver of affection for Elsa while reassuring her that their alliance with Lothor is only temporary.
  • Big Bad: For this series.
  • Creepy Monotone: Speaks in one.
  • Enemy WithinEnemy Without: Starts out as Mercer's evil alter-ego; splits off from him in the finale.
  • Evilutionary Biologist: Wants to revive the dinosaurs to replace humanity.
  • Evil vs. Evil: Fights Lothor during the team-up episode with Ninja Storm. He wins and traps him in one of his jars.
  • Expy: A Big Bad who was a scientist before going Professor Guinea Pig? Sounds like Master Org/Dr. Viktor Adler. Also reminding of the Lizard.
  • Fantastic Racism: Sees Dinosaurs as possessing a DNA superior to Humans', hence his desire to bring them back.
  • Jekyll & Hyde: Anton Mercer invented a formula based around dinosaur DNA that accidentally turned him into Mesogog, and he frequently flip-flopped between himself and Mesogog. However, as mentioned above, they eventually split. Also, while Mercer tries to use his knowledge for good, Mesogog uses it to try and revive the age of dinosaurs.
  • Knight of Cerebus: He comes after one of the silliest main villains ever, but is pretty much everything Lothor wasn't, having no element of comedy to his character and being a genuinely terrifying villain. His complete utter lack of respect for Lothor makes this even more obvious.
  • Knight Templar: He honestly believes he is doing the right thing for the world by trying to wipe out humans and replace them with dinosaurs.
  • Mad Scientist
  • Make My Monster Grow: Pulls this off with his hydro-regenerator that shoots a seed in the sky that makes it rain down a chemical to the remains of the Monster of the Week.
  • Manipulative Bastard
  • No-Nonsense Nemesis: Mesogog never participates in comedic antics, doesn't banter or gloat to the rangers and always advocates the most direct plan for victory.
    • That being said, he does crack a somewhat gruesome joke in Disappearing Act.
      Mesogog: Elsa, please tell me you have a plan to destroy the Power Rangers.
      Elsa shows off a black plant.
      Elsa: I do. I give you Thornox!
      Mesogog: *beat* I've already had lunch...
      Mesogog laughs/hisses and Elsa nervously laughs with him.
  • One-Winged Angel: In the season finale, a replicating one at that, and it just makes him more terrifying
  • Sssssnake Talk: Exactly what his speach sounds like. Rather impressively, he can hiss words that were never supposed to be pronounced this way.

Elsa/Principal Randall | (Actress: Miriama Smith)

  • Badass Adorable: A dark version.
  • The Baroness: Rosa Klebb personality, but she later attempts to pull of the Sexpot variety.
  • Brainwashed and Crazy: When she loses her powers, she looks much more human and acts as if emerging from a daze. She later claims to have been under Mesogog's control, and the Mesogog-free Anton is happy to see her.
  • Child Hater: At least while under Mesogog's control.
  • Clark Kenting: Lampshaded; when her cover is blown, Tommy notices he should have guessed sooner and Ethan references the trope namer.
  • Dark Action Girl: She's the only female villain this season, and takes action.
  • Dean Bitterman
  • The Dragon: She and Zeltrax are co-dragons, but his betrayal leaves her as Mesogog's right-hand woman.
  • Evil Teacher: Or rather, evil principal.
  • Good Scars, Evil Scars: A black, stitched scar runs from her bottom lip to her chin. Ironically, it acts quite a bit like a 'good' scar (vanishing when she transforms, not detracting from her looks, etc.), but marks her as a villain at the same time.
  • Light Feminine Dark Feminine: Older, dressed in all black, and more sexualized than Kira's light femininity.
  • Meaningful Name: Her first name, Elsa, is both a typical Northern-Europe name (or a shortening of 'Elizabeth'), but also the name of the heroine of one of Wagner's operas, Lohengrin, who loves a man she cannot ever see the face of.
  • Redemption Demotion: Loses all her action abilities when she turns good.
  • Old Friend: The 'real' Elsa has an unspecified past with Anton, who asks her for a dance in the last episode.
  • Sadistic Teacher: Sadistic principal.
  • Sycophantic Servant: Brainwashed, yes, but she's utterly loyal to Mesogog.
  • Villainous Crush: On Tommy. It's implied she takes on a younger look with more hair in hopes that he'd notice.

Zeltrax | (Voice actor: James Gaylyn)

  • An Axe to Grind: Unless he's using the Cool Sword instead.
  • Ascended Extra: In Abaranger, Zeltrax was originally a Monster of the Week named Geildon who died in the first two episodes, while his armor was subsequently used by Jeanne, Elsa's counterpart. Here in Dino Thunder, Zeltrax is given an upgrade to The Rival to Tommy, The Dragon (and later, The Starscream) to Mesogog, and lasts throughout the series.
  • Badass Baritone / Evil Sounds Deep: Very deep and guttural.
  • Composite Character: He has two-three Abaranger counterparts. The reason for this is because his basis in Abaranger is a cursed suit of armor worn by multiple users throughout the series.
  • Cyborg: He started out as human, but was rebuilt as a cyborg after sustaining fatal injuries.
  • Hopeless Suitor: He has a thing for Elsa, which may explain why he lets her make snide comments about him. He loses interest in her after his return.
  • It's Personal with the Dragon: He has a serious grudge against Tommy; see Rival Turned Evil.
  • Luckily, My Shield Will Protect Me: One of his weapons.
  • Papa Wolf: He inadvertently created a younger clone of himself named Goldenrod, who was determined to make his "father" proud of him by destroying Tommy. Zeltrax actually did grow to see him as a son, and once he was destroyed in battle, it made him hate Tommy more.
  • Rival Turned Evil: He and Tommy used to work together. After being rebuilt as Zeltrax, he blames Tommy for everything that went wrong in his life, including the accident that led to his transformation.
  • The Starscream: Subverted; the White Ranger tries to conspire against Mesogog with him at some point. Zeltrax, however, immediately warns Mesogog about it. Played straight when he comes back.
  • One-Winged Angel: He gains a super powered form through the special underground spring that flowed beneath the Tree of Life.
  • Undying Loyalty: Toward Mesogog at first. Disappears after he got resurrected.
  • We Can Rebuild Him: How Mesogog brought him back to life.


Hayley Ziktor | (Actress: Ismay Johnston)

Anton Mercer | (Actor: Latham Gaines)

  • Corrupt Corporate Executive: At first.
  • Dark and Troubled Past: He used to work with Tommy on combining dino DNA with technology. The lab and island that they worked on was destroyed, but both Anton and Tommy survived. Anton, along with Tommy, resurface at Reefside. He was not pleased at all to see Tommy had survived.
  • Enemy WithinEnemy Without: With Mesogog.
  • Expy: Of Norman Osborn.
  • Fantasy-Forbidding Father / Follow in My Footsteps: A point of contention between Dr. Mercer and Trent, as Mercer wants to groom Trent for the business world and thinks his drawing hobby and afterschool job at Hayley's are beneath him. In Mercer's defense, some of his lines suggest that he's preparing Trent to handle being on his own in case he loses his internal battle with Mesogog. In the finale, after he is freed from Mesogog's influence, he is much more supporting towards Trent's hobbies.
  • For Science!: Why he created the formula that turned him into Mesogog.
  • Jerkass: At first, especially towards Trent and Tommy, because he tries to keep the fact that he is Mesogog from them.
    • Jerk with a Heart of Gold: Once it's revealed what happened to him, he warms up toward Trent at exactly the same time that Trent discovers his secret, because he allows himself to let down his guard because he no longer has a secret to keep from him.
  • It's All My Fault: Blames himself for the accident that turned him into Mesogog.
    • He's less than thrilled about Trent slowly becoming evil, but blames Mesogog, and insists on his personal lack of choice in the matter.
  • Manipulative Bastard: At first.
  • No Sense of Personal Space: Especially when interrogating Tommy
  • Old Friend: The not-brainwashed Elsa has an unspecified past with Anton, who asks her for a dance in the last episode. They have some Ship Tease as well.
  • Papa Wolf: Towards Trent.
  • Professor Guinea Pig: He accidentally turned himself into Mesagog after experimenting a potion on himself.

Devin del Valle & Cassidy Cornell | (Actors: Tom Hern and Katrina Devine)

  • Aborted Arc: Early episodes showed Devin as slightly more competent than Cassidy as at the time he was to become the Sixth Ranger, but these plans were tossed aside when they realized the Triassic Ranger was just a Red Ranger power up.
  • Alliterative Name: Cassidy Cornell. (And Devin del Valle could qualify, depending on who you ask.)
  • Alpha Bitch: Cassidy, though it's a pretty mild case and she gradually becomes a Lovable Alpha Bitch.
  • Character Development: Cassidy especially. She gives up on exposing the rangers to further her career.
  • Intrepid Reporter: What Cassidy sees herself as, anyway.
  • Last Minute Hookup
  • Pink Is Feminine: Cassidy. Especially when compared to Kira, who isn't even all that masculine.
  • Screw the Rules, I'm Doing What's Right!: Two major instances. Before the below instance, when the Rangers are temporarily depowered and incapacitated (and in Tommy's case, in a coma), Cassidy is given the opportunity for a big break by declaring the Power Rangers having abandoned Reefside, which Devin wanted no part of. When it came time to do the report, Cassidy does the opposite and, against her boss's orders and at the risk of her big break, pledges her continued faith in the Rangers.
  • Secret Chaser: They're rather intent on finding out who the Rangers are in order to become famous.
  • Secret Keeper: In the finale.
  • Those Two Guys: Almost to the point of being Spiritual Successors to Bulk and Skull, considering they spent a chunk of the season trying to discover the Rangers' identities.
  • Unwanted Glasses Plot: Devin tries to avoid wearing glasses. Then an MOTW creates a bunch of Cassidy clones who all start badgering him at the same time.
    "My mom always say to wear my glasses. But no, I'm afraid of looking like a dork!"
  • You Look Familiar:
