Super Dinosaur is an intelligent Tyrannosaurus rex who wears a harness that gives him functional arms and a lot of weapons. He hatched from an egg that Max Maximus stole from inner Earth. Maximus experimented on SD granting him exceptional intelligence and a small size (both relative to a normal T-Rex). SD became friends with the Dynamo family, especially Derek, and when the Dynamos learned about Maximus' evil plans SD sided with them against Maximus. SD acts like a human child of Derek's age. The two are best friends but as the only good dinosaur SD gets lonely.
- Chest Insignia: "SD".
- Clothes Make the Superman: Without his armor he's only a T-Rex. But the armor makes him a true force to be reckoned with.
- Genius Bruiser: Far more powerful han a normal T-Rex (which are already pretty powerful), and way smarter to boot.
- Green-Eyed Monster: Gets jealous of Erin for stealing Derek away all the time.
- Hurting Hero: SD feels increasingly out of place being the only non-human on the team.
- King of the Dinosaurs: He's a Tyrannosaurus rex and also the titular Super Dinosaur.
- Super Prototype: Illustrated by this exchange.Tricerachops: You don't scare me! You were the precursor to my kind—the early model!Super Dinosaur: And I'm still going to beat you!

Derek is the son of the brilliant Dr. Dexter Dynamo. He uses his smarts and an array of gadgets to fight alongside SD. Derek can be a Totally Awesome Insufferable Genius, but he is a hard worker and really cares for his friends and family. Presently he is neglecting his friendship with SD to spend time with Erin Kingston.
- Alliterative Name: Derek Dynamo.
- Gadgeteer Genius: Built most if not all of the gadgets he uses.
- Improbable Age: No older than 15, but he can do battle with all kinds of villains.
- Insufferable Genius: He's shying away away from this, but he spent the first issue talking about how awesome he and team operation are.
- Kid Hero: Generally he plays support for SD, but he can be a hero in his own right.
- Tricked-Out Gloves: Which contain (at least) claws for climbing, a grappling hook, and a variety of bombs.
- Worthy Opponent: Derek is the closest to this The Exile has.

Max Maximus is the former partner of Dr. Dynamo and one of the main villains of the series. He can seem Affably Evil at first glance because of how typically comic booky he is, but in issue five we see new depths to his villainy. His goal is to access Inner Earth and use the Dynore, or as he calls it: Maxinite, to create an army of dino people. And then naturally Take Over the World. Fortunately when he was incarcerated his mind was partially erased of Inner Earth, but he escaped and seeks to find a way back.
- Affably Evil: Arguably subverted. At first glance Maximus is a typical comic book villain. Unsuccesfully using his cronies to fight the heroes and coming up with schemes. Not to mention he's competing with The Exile who is a bit more intimidating. However as the series goes on we're seeing a side of Maximus that sets him aside and makes him a pretty effective villain.
- Arch-Enemy: Shared a past with the Dynamos and created SD. The ante is upped when we learn Maximus kidnapped Mrs. Dynamo and erased her from Derek and and Dr. Dynamo's memories. Arch-enemy indeed.
- Bald of Evil: A bad guy, and bald.
- Card-Carrying Villain: Of all SD's enemies Maximus most seems to revel in being an evil bastard.
- Obviously Evil: Let's see... tattered lab coat, goatee, Bald of Evil, robotic arm with claws... Yup! Evil.
- Villainous Breakdown: Breaks down when he reflects that his Dino Man force is repeatedly beaten by a child and an armed T-Rex.

Formerly The Dragon to Max Maximus. She was tired of his treatment of her and the other Dino-Men so she bailed and joined The Exile. 'Chops is proud of her race and simply wants freedom from oppression.
- Adaptational Attractiveness: Has a rather bulky figure in the comic, while in the show she has a more feminine one.
- Adaptational Villainy: In the TV show, she is working for Max Maximus; as opposed to her comic counterpart, who starts out having defected.
- An Axe to Grind: In a world with ray guns and missiles she uses... a really big axe.
- Badbutt: Because Super Dinosaur is kid-friendly, TC doesn't kill people or swear, but she's a very skilled and cool Dragon.
- Chest Insignia: The Dino Liberation Front emblem, which she's seen with in their introductory episode.
- Cool Mask: A red one that covers the top of her face.
- The Dragon: Formerly to Maximus, then to The Exile by the beginning of the comic. Until surrendering to Earthcore, then being broken out by Tyrannosaurus X.
- Good Costume Switch: Downplayed. In the show, after forming the Dino Liberation Front, the formerly green lights on her armor are now red, and she has an emblem painted onto her chestplate.
- Good Scars, Evil Scars: Her comic counterpart has a big scar under her mask.
- Glowing Eyes of Doom: Her comic counterpart's eyes glow under her mask.
- Graceful Loser: See Screw This, I'm Outta Here!
- Laser Blade: Her axe in the show has greennote energy blades.
- Non-Mammal Mammaries: Despite mostly looking like a dinosaur (i.e. a reptile), she has what seem to be breasts.
- Perpetual Frowner: We've yet to see her in a mood other than annoyed or flat out angry. Sort of Justified in that she's a Dino Man wearing a mask so her expressions may be hard to recognize.
- Screw This, I'm Outta Here!: In #11, after not getting any results or help from The Exile, she and the Dino-Men surrender to Earthcore rather than continuing to fight a battle they couldn't win.
- The Starscream: To Maximus.
- We Can Rule Together: In the episode "Jurassic Golf" of the TV show, after a brief battle with SD, she tries talking him into joining her and Maximus.
A mysterious figure who is fighting for a world ruled by Dino-Men. He is against the Super Dinosaur team as well as Maximus, and in fact rallied some of his Dino-Men to his cause, including Tricerachops. The Exile wields a staff with weaponized Dynore attached. In actuality he's a creature from Inner Earth called a Reptiloid. He is trying to free his people from his brother, Monarch Slinn, by taking over the surface world.
- Adapted Out: Makes no appearance in the TV show.
- Anti-Villain: Yes, he wants to take over the world, but his motivation is the liberation of his people who live under the oppression of his brother and in fear of dinosaurs.
- Hoist by His Own Petard: In #9, it's his own staff that Derek finally incapacitates him with.
- No Name Given: When he was exiled he was forced to give up his birth name. His own brother nearly forgot it.
- The Exile: He actually was exiled from his homeland.
- The Reveal: In Issue #9 it's revealed that he is a Reptiloid.

A "failed" clone of Maximus. He was created using dino DNA to aid the cloning process, and as a result he slowly becomes more dino and less man. In Issue #18, when his transformation is completed, he renames himself to Tyrannosaurus X and cements himself as a new evil power for Derek and SD to contend with. And he is no joke.
- Attack Its Weak Point: During his and SD's first fight against T-X, Derek manages to land a hit on one of his opponent's energy ports, weakening him.
- Cloning Blues: Before his transformation is complete he seems to suffer ignominy from his creator and physical stress from the transformation.
- Genius Bruiser: Minimus has the same intellect as Maximus, and by the time he's fully transformed, he possesses extraordinary physical prowess.
- Made of Iron: T-X is much more durable than the already hardy Dino-Men. It took a building blowing up around him to knock him out for a few minutes.
- Metamorphosis: The degeneration process happens over the course of many issues and is apparently very stressful for him.
- Near-Villain Victory: Probably the nearest of any villain yet. SD and Derek have never been so soundly trounced.
