Characters from Beetleborgs.
- Animorphism: Accidentally gain the ability to turn into beetles. This happens when they attempt to use Flabber's spellbook to restore their powers after Nukus destroyed them.
- Character Tic: Each of them has one they tend to use when activating their civilian powers. Drew gives a nod of his head, Jo cracks her knuckles, Roland snaps his fingers, and Josh dusts his hands.
- Combat Pragmatist: Unlike the Power Rangers, they're very willing to use their mecha against human sized opponents.
- De-Power: Temporarily, when their original Beetleborg powers were destroyed (though they kept their civilian powers).
- Japanese Beetle Brothers: Drew and Roland are this in both of their incarnations. Jo can fit into this trope in her Red Striker Beetleborg form, as it's based on a female Japanese rhinoceros beetle.
- Kid Hero: Practically the whole point of the show.
- Older Alter Ego: Their transformed states appear to be full grown adults, even if their voices don't change. It seems most people don't notice they aren't.
- Only Sane Man: On one side, there is a haunted house full of classic horror characters pulling all kinds of stupid antics and on the other side, there are comic book villains trying to take over the world. And yet, the kids don't seem even slightly fazed by this.
- Secret Identity: The three are fairly careful about maintaining theirs.
- Super Mode: Mega Blue Beetleborg for Drew in season 1, Mega Spectra Beetleborgs for all three in season 2.
- Two Guys and a Girl: Their ensemble for most of the series. Temporarily broken when Josh joins the team for a few episodes.
- Wish Fulfillment: Taken literally, as they wished to become the superheroes they were fan of and got their wish.
Andrew "Drew" McCormick (Blue Stinger Beetleborg, later Chromium Gold Beetleborg)The leader of the Beetleborgs.
- BFG: The Thunder Stinger when he has his original Blue powers.
- Brother-Sister Team: With Jo, though Roland is there to balance them out.
- The Leader
- Mind over Matter: Gains telekinesis as his "civilian power".
- Super Mode: Mega Blue in season 1, Mega Spectra Chromium Gold late in season 2.
- This Is a Drill: Stinger Drill.
Josephine "Jo" McCormick (Red Striker Beetleborg, later Platinum Purple Beetleborg)The only girl on the team. She is also Drew's sister.
- The Big Girl
- Brother-Sister Team: With Drew, though Roland is there to balance them out.
- Cute Bruiser
- The Nth Doctor: Via a magical mishap. Replacing the only girl with someone who looks nothing like her? Then do what Beetleborgs did, and say that a spell was placed on Jo which caused her to look and sound different, and then a second spell makes Muggles see her old self, but not the main characters (or viewer.) That's a smooth save right there.
- Gender-Blender Name: "Jo", which could easily be mistaken for "Joe".
- One of the Boys
- Otaku Surrogate
- The Smurfette Principle: Of the Beetleborgs team.
- Super Mode: Mega Spectra Platinum Purple late in season 2.
- Super Strength: Her "civilian power".
- Super-Strong Child: She's nine when the series starts and gained super strength with her Beetleborg powers.
- Tomboyish Baseball Cap: Wears it backwards.
Roland Williams (Green Hunter Beetleborg, later Titanium Silver Beetleborg)A good friend to Jo and Drew and also the son of Aaron, the owner of Zoom Comics.
- Black Best Friend: He's black and Drew's best friend.
- The Lancer
- The Smart Guy: Of the Black and Nerdy variety.
- Super Mode: Mega Spectra Titanium Silver late in season 2.
- Super Speed: His "civilian power".
Josh Baldwin (White Blaster Beetleborg)
- Fourth Beetleborg: For a few episodes of season 1.
- Flat-Earth Atheist: Despite personally witnessing Shadowborg's rampage in the town (which included buildings being blown up), it takes way more effort than it should to convince him to become the White Blaster Beetleborg.
- Good Counterpart: Created specifically as a counterpart to the Shadowborg.
- Good Needs Evil: White Blaster was created as an antithesis to Shadowborg. When Shadowborg is defeated, Josh loses his powers.
- Invisibility: His "civilian power". Loses it along with the rest of his powers.
- Put on a Bus: After Shadowborg's destruction, Josh loses his powers, and says he'll be around if the team ever needs him again... And he was never seen again.
- Unskilled, but Strong: Was made to be the strongest Beetleborg, but Shadowborg points out he's also the least skilled, which is why despite being made to destroy Shadowborg he can't beat him head on.
The Astral BorgsA group of insect based superheroes drawn by Art Fortunes when he was a kid. They can be summoned into the real world by throwing their corresponding Astral Coin. The Astral Borgs help out the Beetleborgs against their foes, the Mantrons, during the Astral Coins saga.
- Animal Themed Super Being: All of them are based on insects generally considered harmless and sometimes even pretty to look at. Dragonborg is based on a dragonfly, Fireborg on a firefly, Lightningborg on a cicada and Ladyborg on a butterfly.
- Arm Cannon: Fireborg's Astral Launcher.
- BFG: Ladyborg's Astral Bazooka.
- Dual Wielding: Lightningborg's twin Astral Sabers.
- Make Me Wanna Shout: Lightningborg can emit damaging sound waves from his chest.
- No Celebrities Were Harmed: Dragonborg really sounds like an imitation of Sean Connery.
- Put on a Bus: Like Josh before him, after the Beetleborgs finally get their hands on Roboborg, the Astral Borgs tell them they'll be there when the need arises, but are subsequently never seen again.
- The Cape: Their personalities tend towards this. Justified, as they're comicbook characters created by a little kid.
- The Smurfette Principle: Ladyborg is the only female in this team of borgs.
- Super Prototype: All of them were drawn by Art Fortunes when he was a kid. These drawings inspired him to create the Beetleborgs comics and can therefore be seen as the prototypes to the Beetleborgs. However, it is obvious that the Astral Borgs are much stronger than the Beetleborgs, as they can easily defeat the Mantrons, while just one Mantron is more than enough to defeat the Metallix Beetleborgs (who are explicitly stronger than the Beetleborgs). They can also teleport, which the Beetleborgs can't.
GeneralA group of classic horror monsters living in Hillhurst. They are the reason why the people of Charterville proclaim the house to be haunted.
- Bullying the Dragon: Insist on trying to eat the kids despite the three being superheroes who are able to handle them with their civilian powers, and could crush them in a second with their Beetleborg powers if they really wanted to.
- Harmless Villain: Except for Flabber.
- The Millstone: They frequently cause trouble for the kids for the most selfish of reasons. A good example is when they wanted to give the villains the last Astral Coin needed to control a Humongous Mecha. In return, the villains would leave Hillhurst alone. Somehow, they didn't realize that if this deal succeeded, the entire world would be in trouble.
- Spotlight-Stealing Squad: Their antics sometimes receive more screen time than the kids' fight against the villains.
- With Friends Like These...: The monsters frequently try to eat the kids or hinder them otherwise. Despite this, the kids always come to their aid when they need it.
FlabberA phasm who was imprisoned in a pipe organ, until he was freed by the kids. He was the one who made them Beetleborgs and assists them in other ways during their fight against the Magnavores and later Crustaceans.
- Big Good: Genuinely cares for the kids, provided their powers, and helps them in any way he possibly can.
- Fingerless Gloves: Yellow ones at that.
- Large Ham: It says something when the kids occasionally have to tell him to be serious.
- Literal Genie: A benevolent example, as he did not let the kids stick with a badly executed wish and instead gave them what they really wanted after rectifying his mistake. Flabber is also a literal genie in another way, as he frequently uses his magic to literally depict puns and expressions.
- The Mentor: Of the Beetleborgs.
- More than Three Dimensions: Is from the seventh dimension.
- Nice Job Breaking It, Hero!: Flabber granting the kids' wish of becoming Beetleborgs caused the Magnavors to escape the comic book and into the real world, which makes him the cause of the series' entire conflict.
- No Celebrities Were Harmed: Based on Liberace, Elvis Presley, and Jay Leno. The Tonight Show with Jay Leno commented on this. Needless to say, Jay was a bit put out...
- Papa Wolf: He genuinely does care for the kids, and is quick to protect them from his roommates. When the Phantom tries to kidnap Jo, if it weren't for them being equal in strength, Flabber would've turned him into a candlestick for it without question.
- Reality Warper: Is capable of being this to a certain degree.
- Scaled Up: If he wants to be terrifying, his form of choice is a giant dragon he's assumed on several occasions.
- The Social Expert: Capable of preventing other Hillhurst monsters from torturing the Beetleborg kids.
- Token Good Teammate: The only one of the Hillhurst crew who willingly helps the kids.
Count FangulaA rather ineffectual vampire.
- Animorphism: As with all classical vampires, Fangula can change himself into a bat.
- Classical Movie Vampire: Is dressed as a thinly disguised parody of the classic portrayal of Dracula.
- Friendly Neighborhood Vampire: Zigzagged. He is certainly a huge jerk to the kids and really wants to suck their blood, but never leaves Hillhurst to hunt for blood. In fact, when his superior, Vlad the impaler, demanded he should do so, Fangula fell into a depression, rather than going out to suck blood. This implies he really does not want to be a vampire.
- Our Vampires Are Different: He can survive in the sun with no problem.
- The Smart Guy: He specializes in witchcraft.
- Translator Buddy: He is responsible for translating whatever Wolfie is saying.
FrankenbeansLike his name suggests, he is a parody of Frankenstein's monster, only with the mentality of a toddler.
- The Big Guy: Out of all the Hillhurst monsters.
- Dumb Muscle: Is about as strong as Jo at times, but due to lacking a brain, he is the dumbest monster living in Hillhurst.
- Einstein Hair: It's pretty wild.
- Frankenstein's Monster: His name clearly suggest he is based on this.
- Hulk Speak: A result of his lacking intelligence.
- Manchild: Is the biggest of the monsters, but has the maturity of a toddler.
- Ugly Cute: He certainly looks scary, but his childlike behavior still makes him endearing to watch.
MumsAn undead Egyptian mummy who somehow ended up in America.
- And I Must Scream: Was apparently mummified alive as punishment for kissing Cleopatra. Since this is a kids show, mummification simply involved wrapping him in bandages and shutting him in a pyramid. Still, the priest who mummified him did curse him with eternal life, while being sealed in a pyramid.
- Dem Bones: Briefly shown what he looks like without his bandages.
- Hidden Depths: He actually apparently knows how to do magic himself and is decent with it, but rarely ever uses it.
- Jerkass: Usually the least sympathetic of the Monsters.
- One-Winged Angel: Can transform into a reaper-like form by unwrapping his bandages. Only did this in the first episode though. Other episodes in which he is unwrapped simply show his skeleton falling apart.
- Shock and Awe: Seems to be able to send out electrical shocks in his reaper form.
Wolfgang "Wolfie" SmithA werewolf who was Fangula's previous roommate in another haunted house. He wanted to move in at Hillhurst, much to the displeasure of the other monsters, but ultimately got permission to stay, as he would otherwise be recruited to the Magnavores.
- Badass Normal: While being a werewolf is anything but normal, Wolfgang has none of the fancy powers the Beetleborgs and their enemies have, yet still managed to score some victories against the Beetleborgs' enemies. In fact, if it wasn't for Wolfgang, the villains might have succeeded in some of their plans.
- Crouching Moron, Hidden Badass: Don't push Wolfie too far - he will fight back, even against Nukus, trying to help the Beetleborgs in their first battle against the villain. It didn't help much, but he was actually able to touch the guy, which the heroes couldn't.
- The Heart: The nicest and most sympathetic of the Hillhurst Monsters. While the other Hillhurst Monsters care only for themselves and their house, Wolfgang helped the kids with their battle against the villains at some occasions. However, he still has some selfish tendencies and, like his roommates, still tries to eat the kids when he's hungry.
- Our Werewolves Are Different: He's permanently in humanoid wolf form.
- The Unintelligible: He express himself with howling and barking, forcing Fangula to translate his language.
GhoulumA living statue standing in the entrance hall of Hilhurst
- Brainwashed and Crazy: Was forcibly turned evil and mind controlled by Noxic in one episode, but ultimately saved by the Beetleborgs.
- Living Statue: Exactly.
- The Quiet One: Says and does very little compared to his roommates. He is, after all, a statue.
- The Unintelligible: Prefers grunts rather than words.
- The Chick: Of the Hillhurst monsters. Also The Smurfette Principle.
- The Faceless: She is only seen as a Jawa-like pair of eyes under a hood. Whenever she takes it off, she's facing away from the screen, and the person who is seeing her tends to run screaming.
- In the Hood: And for a good reason...
- Sixth Ranger: To the House Monsters in Metallix.
- Sticky Fingers: Really likes to steal other peoples stuff, to the point where she is usually the first suspect whenever something is missing.
- Token Good Teammate: Played With. She's a thief and a Troll but she's also the only one of the house monsters besides Flabber who doesn't try to eat the kids on a regular basis.
- Troll: She loves messing with others. She claims it's a racial trait.
- The Trickster: in her first appearance.
Aaron WilliamsRoland's father and owner of Zoom Comics.
- Put on a Bus: Suddenly got a job as a sales representative for Beetleborgs comics, forcing Roland's mother Abbie to take over Zoom Comics.
- Reasonable Authority Figure
- Team Dad: Though he doesn't know about the Power Trio's abilities.
Nano WilliamsRoland's rather eccentric, but cool grandmother. She is also seen helping Zoom Comics.
- Amazingly Embarrassing Parent: To Aaron.
- Black Boss Lady: Though she's not the true owner of Zoom Comics, she sometimes acts like it.
- Cool Old Lady: She likes to ride motorcycles, is a skilled martial artist and rather fights the Monster of the Week than fleeing from it.
- Never Mess with Granny: Do not get on her bad side, as she does not hesitate to use her martial arts skills against you.
- Tomboy and Girly Girl: The tomboy to Abbie's girly girl.
Abbie WilliamsRoland's mom, who takes over Zoom Comics when her husband leaves for business.
- Suspiciously Similar Substitute: She's not that different compared to her husband.
- Tomboy and Girly Girl: The girly girl to Nano's tomboy.
HeatherA girl who works at Zoom comics. She seems to be well liked, as she has to constantly put up with the advances of Trip and Van, while Drew is is just to shy to admit he loves her.
- All Love Is Unrequited: Drew has a crush on her but is too shy to tell her.
- Chuck Cunningham Syndrome: Just kind of stops appearing halfway the Metallix season.
- Damsel in Distress: Occasionally, most notably in a daydream where Drew first fantasizes about being a Beetleborg.
Arthur "Art" FortunesThe artist of the Beetleborgs comics. He sometimes comes to help out by drawing new weapons and vehicles for the kids, which are brought to the real world by Flabber.
- Einstein Hair: Though he does comb it down sometimes.
- Full-Name Ultimatum: Refers to Les as "Lester" when the two are verbally sniping at one another.
- Mad Artist: A bit eccentric but a rare good example of this trope.
- Meaningful Name: He's the creator of the Beetleborg comics, which makes him an "artist" that made "fortunes."
- Nice Job Breaking It, Hero!: He blurts out who really created Nukus in front of him, leading to Nukus gaining allies and a reliable source of monsters.
- Sibling Yin-Yang: With his older brother Les. He's good and white-haired; Les is evil and dark-haired.
Dr. Baron von FrankenbeansThe mad scientist who created Frankenbeans. He is a recurring visitor of Hillhurst whose experiments cause all sorts of trouble for the monsters and kids, though not on purpose, but rather because the experiment went wrong.
- Dramatic Thunder: Every time he introduces himself and sometimes even when someone else mentions his name, the rumbling of thunder can be heard.
- Herr Doktor: As you can tell from his name.
- Mad Scientist: A rare benevolent example, as he is a really well meaning man. He created Frankenbeans and considers himself his father.
Trip and VanTwo insanely wealthy brothers who frequently try to bully the Beetleborg kids, but always end up being victims themselves as the kids secretly use their superpowers on them.
- Pet the Dog: During the Christmas special, they bring a Christmas dinner to replace the one that got destroyed, purely out of Christmas spirit.
- Put on a Bus: In season 1's finale, they go to live on their father's country estate.
- Sitcom Archnemesis: Are this to the kids. They often try to hinder the kids in rather petty ways.
- Rich Jerks: They're a pair of wealthy brothers who antagonize the main characters.
- Screw This, I'm Outta Here!: When Borgslayer starts wreaking havoc, they decide they've had enough and leave town... then return for a short while at the insistence of Nukus, telling the Beetleborgs the technique that destroys Borgslayer. Once they've passed on the information, they depart for good.
- Unwitting Instigator of Doom: They dared the heroes to go into Hillhurst, setting the plot of the series in motion. Including all the monster attacks.
DudleyVan and Trip's butler, who always accompanies them on their misadventures.
The MagnavoresThe first set of villains.
- Attention Deficit... Ooh, Shiny!: The main trio is easily distracted by pretty much everything they encounter during their missions for Vexor. An example is when they were send out to steal comic books so Vexor could create an army of monsters. During said mission, they decided to steal donuts, getting them into trouble with the police.
- The Empire: According to this card, they are the rulers of the Magnavorian empire in the comic books.
- For the Evulz: There never seems to be a reason for their evil behavior. While the villains in sister show Power Rangers have stated they want to take over the world, the Magnavores have no such motivation.
- Refugee from TV Land: Are comicbook characters come to life.
- Terrible Trio: Jara, Noxic and Typhus fit this trope.
- Harmless Villain: They never seem to pose any real threat due to their incompetence. While Vexor seems capable enough to avert this trope, he rarely actually acts directly, only via elaborate plans (which are normally fairly elaborate). It's little wonder that the Vile Villain, Saccharine Show Shadowborg is Vexor's only minion he actually liked.
VexorThe first villainous leader.
- Big Bad: Of season 1.
- The Chessmaster: Tends to come up with elaborate plans for dealing with things rather than using brute force and is definitely smarter than his underlings.
- Evil Is Petty
- Fingerless Gloves
- Non-Action Big Bad: Apart from one short skirmish with the Beetleborgs, which he lost (though what, if anything, his One-Winged Angel form is capable of is never shown), he never takes any direct action against them. He's more keen on making plans and schemes than fighting directly, and many of his plans fail more due to his minions incompetence than anything.
- Not So Above It All: During the Christmas special, Jara gives him a stocking and, while he still berates them for being idiots, he still seems to enjoy it and take a break from evil for the night.
- Not So Stoic: While he has his hammy moments, he's normally rather subdued and rarely ever raises his voice. However, towards the end of the series the Terrible Trio constantly failing clearly begins to get on his last nerve and he starts raising his voice.
- One-Winged Angel: Briefly turns into a monstrous giant after being defeated in his normal form. How strong this is is never shown.
- Orcus on His Throne: Does not really take active action against the Beetleborgs. Though he does make plans and do other things, such as trying to seal the portal to the second dimension so that the Magnavores couldn't be defeated and creating Shadowborg.
- Surrounded by Idiots: Feels this way about his generals. Given he's far smarter than they are and many of his plans fail due to their incompetence, he has a point. Shadowborg is his only minion he actually likes because he's actually serious and competent.Vexor: When am I going to learn not to rely on you bumbling boneheads? If there's a brain cell among you, it's dying of loneliness!
- We Need a Distraction: Many of his directly ordered monster attacks are explicitly intended more as distractions from his intentions than his main attack.
- The Brute
- Evil Sounds Deep: Has a very low guttural voice.
- Villainous Glutton: Frequently stuffs himself through the mouth on the top of his head.
- The Baroness
- The Dragon: Even with levels of The Starscream.
- Fingerless Gloves
- What the Hell Is That Accent?: She sounds either like a Fake Russian or a Vampire Vord.
- All Your Powers Combined: Steals the other Beetleborgs' powers.
- Always Someone Better: To the Terrible Trio, being competent, serious, and actually capable of doing what Vexor wants. They're naturally incredibly jealous of him for it.
- Ax-Crazy: While mostly subdued, it's clear he's a sadistic monster who enjoys attacking the town and actively aiming at innocent civilians.
- Badass Boast: A large amount of his dialog consists of these. He lives up to them.
- Deadpan Snarker: In contrast to the other villains, he doesn't joke or go Large Ham, rather keeping his quips to deadpan one-liners.
- The Dragon: To Vexor during his arc.
- Evil Counterpart: To the Beetleborgs as a whole, but mostly to Drew, as Shadowborg is created from a part of his armor.
- Evil Knockoff: Is an evil, fully mechanical copy of the Blue Stinger Borg created from his armor.
- Dark Is Evil: He's evil and has a black color scheme.
- Implacable Man: When first introduced, nothing the heroes do, including making weapons and powers explicitly intended to kill him, does much to phase him. It takes Drew risking turning himself evil with Vexor's Energy Axis to finally take him down.
- Killed Off for Real: Unlike every other villain, Shadowborg isn't a comicbook character who can be sent back. He's actually killed when destroyed by Mega Blue Beetleborg. While Art adds him to the comic, even if that version was ever summoned, it'd not be the same one.
- Knight of Cerebus: He's definitely a more serious and threatening villain than the other season 1 bad guys.
- Kryptonite-Proof Suit: He's not originally from the comics so he can't be sent back into a comic book like most other villains and has to be destroyed outright.
- Power Parasite: Steals the three original Borgs' powers after beating them.
- Robotic Psychopath: Is a robotic copy of Blue Stinger Borg, and a sadistic, Ax-Crazy monster who is clearly enjoying attacking the town and tormenting the kids.
- Vile Villain, Saccharine Show: Is much more dangerous and powerful than anything before, and completely lacks any humorous traits. He's also the first villain to actively be show aiming at people with intent to kill. Is it any wonder he's Vexor's only minion he actually liked?
The second group of villains. Unlike the Magnavores, who come directly from the Beetleborgs comics, this group comes from sketches made by Art Fortunes' deranged and criminal brother Les Fortunes. This probably explains why they are more effective at being villains compared to their predecessors, the Magnavores.
NukusThe new Big Bad. In his first appearance, he proves himself to be more intelligent and competent than Vexor - not only does he destroy the paper he was summoned from (and later a second drawing of himself) to keep from being readily sent back into the two-dimensional world, he gets rid of the other villains in an elaborate scheme before taking over. He is also more proactive compared to Vexor, as he frequently goes to the battlefield himself.
- Achilles' Heel: He does have one major weakness: if his sword is used by anyone but him to create a monster, not only can he not control it, if it's not sent back to the 2nd dimension in time, it creates another rift like the one that happened when Borgslayer was destroyed, only this time it'd take all the Crustaceans with it, including Nukus. This heel is never exploited though, in part because he's smart enough to not let the Borgs know the one time he's forced into an Enemy Mine because of it.
- Batman Gambit:
- His entire first plan consists of exploiting the way the Beetleborgs typically react when Hillhurst is attacked to destroy the Battle Base and Gargantis, and play Vexor in such a way he can tell him to his face that Borgslayer's destruction will take the Magnavores with him without Vexor once suspecting he's going to be betrayed.
- His plan to find the Lost Comic consists of send Les to try and get the location out of Art...knowing Les will likely fail, but in doing so the heroes will find the Lost Comic thinking the Crustaceans are looking for it, leading them right to it.
- Big Bad: Of Metallix.
- Catchphrase: "(Insert Monster's Name Here)! Arise!", whenever he brings something out of the comics. It's implied it's necessary for his sword to work, as Les and Vilor have to say it when they do it. Given he doesn't just summon monsters, this leads to some interesting statements, especially given Nukus's generally serious delivery and lack of comical traits.Nukus: (When summoning a normal guy from an insurance ad) Average Man! Arise!
- Explaining Your Power to the Enemy: Defied. He tells the heroes how to beat Borgslayer...with a method that's completely worthless on him. He also keeps how his sword brings monsters into the 3rd dimension and how it works very close to his chest, as until it became relevant for Les and Vilor to know after accidentally causing his Achilles' Heel to come into play, and even then makes sure not to tell the Beetleborgs it when forced into an Enemy Mine with them.
- Eye Beams: How he destroys the aforementioned two drawings.
- Knight of Cerebus: While the show still stays lighthearted and goofy after Nukus's appearance, he is much more of a threat compared to Vexor, who was just there to berate his minions for failing. He's also presented as much more intimidating than the Magnavores ever were.
- Large Ham: Nukus really does not know what subtlety is, as every line spoken by him is this.
- Manipulative Bastard: Sets up Vexor and his minions to be defeated and sent back to the comic books, allowing him to take over as the new villain. His entire plan to destroy the Beetle Battle Base and Gargantis revolves around knowing exactly how the Beetleborgs will react.
- No-Sell: Having successfully defeated Borgslayer by triangulating their firepower, the Beetleborgs try to get rid of Nukus with the same tactic. He shrugs it off with no problem, then reveals he knew the technique wouldn't work on him - that's why he told them about it (via proxy) in the first place.
- Obviously Evil
- Pet the Dog: Rewards a kid who helps him find the prison by turning his dog into his favorite animal, a monkey.
- Stock Dinosaurs: Is based on a triceratops.
- Super Mode: Mega Nukus, gained from touching Les's transmogrifier device.
- The Comically Serious: While a Knight of Cerebus and a dead serious character, that very same serious can cause for some humor given who he's often sharing the screen with, or some of the stuff he ends up having to say.
- The Starscream: To Vexor. Though a rather competent one, since he permanently takes over the position of Big Bad
- Villain Decay: Was basically unstoppable in his first appearances, before ending up failing to fight them again later; then again, the Beetleborgs got new upgraded armors, most likely didn't fall to the same tricks anymore, and he still could handle them pretty well in a fight. It should be noted that he never actually gets beaten so badly he has to retreat for his entire run, and normally simply retreats when he feels the situation has become unfavorable.
HorribelleNukus's female second-in-command. She is a mantis-based warrior, armed with two blades.
- The Dragon: To Nukus.
- The Smurfette Principle: The only female among the villains. Also the only one without a Super Mode, leading to her forcing Les into creating a new weapon for her: the Astral Axe, and the giant mecha Boron that comes with it.
- Slaying Mantis: Her motif is that of a praying mantis.
- The Starscream: Temporarily turns into this after being jealous of Nukus and Vilor's super modes, while not getting one herself. This only lasts for one episode.
- The Brute: Never seems to come up with any plans of his own and is only send out to do the Crustaceans' dirty work.
- Butt-Monkey: While Nukus and Horribelle are both presented as serious and dangerous villains, Vilor normally gets treated like a joke and suffers far more defeats than either of them. He's also the only one of the three the heroes manage to beat without transforming. This status is why he had Less turn him into Super Vilor in the first place.
- Fish People: Looks like a humanoid fish.
- Super Mode: Had two different super modes, albeit only temporary. The first one, called Super Vilor, was used in the Astral Coins saga. It was drawn by Les Fortunes and realized by Nukus. The second one is Mega Vilor, gained from touching Les's transmogrifier device. Due to stock footage constraints, he doesn't have them very long, as he reverts back to his original form after just one battle.
- Took a Level in Badass: Super Vilor is way stronger than his original form, as in it he's even stronger than the Mantrons. Unfortunately for him, he doesn't keep it long, as it effectively takes a trip back to the second dimension for him.
Lester "Les" FortunesArt Fortunes' brother. Les is also an artist, albeit one with a much darker taste compared to his brother, seeing as the characters he has drawn are more threatening than whatever Art came up with. He somehow ended up in jail, though the series never elaborated on why.
- Breaking Out the Boss: Inverted. His creation, Nukus, breaks him out... but makes it clear that he's in charge.
- Bullying a Dragon: He has zero problem talking back to Nukus despite Nukus being leagues stronger than him and having no qualms about killing people. Justified, however, as Les is far too valuable to Nukus to kill, something Les seems aware of.
- Cut Lex Luthor a Check: It's shown that Les is a legitimately brilliant artist and the one comic book that he manages to publish with help from Nukus sells like hotcakes. Despite that, he became a criminal and later a supervillain.
- Einstein Hair: It's even wilder than his brother's.
- Evil Genius: Creates Nukus and all of his monsters.
- Full-Name Ultimatum: Refers to Art as "Arthur" when the two are verbally sniping at one another.
- Mad Artist: Mad enough that he's willing to work for Nukus and draw him new monsters to use against the Beetleborgs.
- Nice Job Fixing It, Villain!: After the Beetleborgs try (and fail) to summon Boron in the finale, he inadvertently tells them the extra word they need to do so.
- Nightmare Fetishist: His genre of choice is Horror Comic Books and his monsters are basically horror movie monsters. Notably, the Booger Man's Your Worst Nightmare powers are considered amazing inspiration for the guy, and after a brief scare is excited to draw what he got in his nightmare.
- Noodle Incident: What was he in jail for, anyway?
- Screw This, I'm Out of Here!: After the Beetleborgs have taken control of Boron, he decides to go back to jail for some peace and quiet.
- Sibling Yin-Yang: With his younger brother Art, who is good and white-haired, while Les is evil and dark-haired.
- The Starscream: Tries this on several occasions, but fails horribly at it.
- Who's Laughing Now?: When he gets the fully powered Astral Saber, he briefly puts the Crustaceans at his mercy with it and Nukus can't do anything about it until Wolfgang manages to swipe it back.
A group of four evil Borgs drawn by Les Fortunes when he was a kid and brought to life by Nukus when he found said drawing. They are Scorpix, Centepix, Mantix and Hornix, who, as their names suggest are based on a scorpion, centipede, mantis and hornet.
- Animal Themed Super Being: All four are based on predatory arthropods:
- Chest Blaster: Centepix has a sphere-like one exposed when his chestplates open vertically.
- Curb-Stomp Battle: Are at the receiving end of one against Roboborg during the latter's first appearance. This results in them being sent back to the comics.
- Dual Wielding: Mantix has two blades resembling a praying mantis' claws.
- Knight of Cerebus: Their first appearance shows them effortlessly wiping the floor with the Beetleborgs, suggesting they really need to up their game before the same thing happens again.
- The Psycho Rangers: Not to the Beetleborgs themselves, but rather to their backup team; the Astral Borgs.
