Voiced by: Corey Burton
"Evil? No... VISIONARY! I feel power building inside me! I see a world that only I can create! It was Azmuth who thought me flawed! He gave me the name Malware... But I am not the flawed one. It's all the rest that are inferior! They bend and stretch... mimic and manipulate what others have created... I do not upgrade others' creations; THEY UPGRADE ME! And I will upgrade myself with Azmuth's greatest creation!"

Malware is a psychotic Galvanic Mechomorph who serves as the main antagonist in the first 2 arcs of Omniverse. He was an incomplete Galvanic Mechamorph created accidentally by Azmuth during the development of Galvan B by shutting down the Helix (the device that created the original Galvanic Mechamorphs) right while he was being produced. As a result, Malware was born corrupted, with the ability to absorb technology and gain its ability instead of upgrading it. Azmuth spent years developing a new Helix in order to cure him, but Malware eventually lost patience and stole it from him, using it to upgrade himself into a form that apparently eliminated his need for energy while retaining his old abilities. After that, he vowed to absorb the Omnitrix in order to gain its abilities. After destroying Ben's Feedback form, he was seemingly killed when Ben overloaded him with the Omnitrix. Somehow, he survived and returned to menace Ben years later.


  • Aborted Arc: The end of "Malgax Attacks" hinted that turning him into a suit for Vilgax may have brought him back to life, but this was the last time he made any sort of appearance before the series ended. Had the series continued after arc 8, he would have been featured as a potential member of the new Negative 10.
  • Anti-Villain: He started out as a very twisted Type II. However, once he got upgraded, he became a straight villain.
  • Arch-Enemy: While only appearing in one series Malware's many battles with 11 and 16 year old Ben and the level of terror, dread, and disdain between the two gives Malware a claim to the title. Killing Feedback, more or less, for half a decade is a very personal blow and Malware is one of a very few number of villains who Ben has shown to be afraid of. He notably retains an air of dread and fear around him that makes him stand out in Omniverse compared to many others.
  • Arc Villain: Of the first two story arcs, having recruited Khyber to collect the DNA required to complete the Nemetrix. Eventually, he was the one whom Ben needed to stop.
  • Arm Cannon: His right hand became one after he absorbed the Tachyon Cannon.
  • The Assimilator: His ultimate goal is to assimilate Galvan Prime and become a living planet.
  • Ax-Crazy: When told that the Tachyon cannon he absorbed could kill humans within a hundred miles, Malware states that he considers that "a bonus".
  • Back from the Dead: He somehow came back to life 5 years after his "death". And in "Malgax Attacks", it's implied that he might have come back to life due to him seeping out of the remains of the fight with Ben and Vilgax, who was wearing Malware.
  • Badass Bookworm: Though it’s not shown often, Malware has a degree of scientific and technological know how.
  • Bad Boss: At times, he has shown to be impatient with Dr. Psychobos and Khyber, even to the point of threatening them.
  • Bad Powers, Bad People: A power-hungry sociopath with the ability to upgrade himself by destroying technology, and sustains himself by cannibalizing people of his own kind.
  • Be Careful What You Wish For: He wanted the Omnitrix. Ben gave it to him... and its energy overloaded him, almost killing him.
  • Berserk Button: Don't imply he couldn't possibly defeat Ben and don't call him defective. Destroying Ben's favorite form Feedback simply for spite on top of the other atrocities he's committed has made him one for Ben.
  • Big Bad: For the flashbacks in Omniverse, as well as being part of the Big Bad Duumvirate in the present day of the first two seasons.
  • Big Bad Duumvirate: With Dr. Psychobos and Khyber for the first two seasons of Omniverse.
  • Big "NO!": When Blukic and Driba stop him from corrupting Galvan Prime's core
  • Book Ends: Ben and Malware's final showdown takes place on the same planet they first met: Galvan Prime.
  • Boomerang Bigot: He is viciously racist toward the rest of his own kind. Unlike most examples, however, this does have some basis as he is an anomaly amongst Galvanic Mechamorphs and has deluded himself into believing what makes Azmuth see him as defective is in fact what makes him superior to them.
  • Breakout Villain: Out of all of the antagonists introduced in Omniverse, he quickly became very popular and, after the first three arcs were completed, had a major, posthumous role in "Malgax Attacks" near the end of the series that strongly hinted that he was going to come back to menace the heroes.
  • Calling the Old Man Out: His rant to Azmuth in "Showdown, Part 2".
  • Cannibalism Superpower: Has the ability to upgrade himself by consuming tech.
  • Character Development: In his first chronological appearance, he was driven mostly by his ego and relied more on raw power in a fight. His later appearances in the timeline reveal that he's since become a very adept planner who learns from his mistakes and can easily feign those flaws as well as becoming aware of when he should surrender versus when he shouldn't.
  • The Chessmaster: He has been behind the plot of using Khyber to collect the DNA required to complete the Nemetrix.
  • Classic Villain: He represents Pride, Ambition, and Wrath.
  • Combat Pragmatist: He sometimes pretends to be unconscious to surprise opponents.
  • Contrasting Sequel Antagonist: Rather than being a subdued, well-known flesh-and-blood megalomaniac in lieu of Vilgax or Aggregor, Malware is mechanical, only has his eye on revenge, tries his hardest to stay off the grid, and is rather bombastic.
  • The Corruption: He infects technology and incorporates it into himself.
  • Creepy Monotone: He has this in his earlier appearances. He became more bombastic later on.
  • Death by Irony: He ends up defeated by a combination of the other Galvanic Mechamorphs (who he despised to the point of trying to annihilate them) and Ben as Feedback (the very form he had destroyed to scar Ben).
  • The Dreaded: He has become this in the present. Ben becomes Dead Serious the moment he's mentioned and Azmuth drops his Insufferable Genius persona the moment that he thinks that Malware might be on Galvan Prime. You have to be seriously bad news to make those two take something seriously. And even after he's defeated, he's still this. In "Malgax Attacks", the mere fact that Malware's remains are missing is just enough to send Ben, Max, and Azmuth into a panic.
  • Drunk on the Dark Side: After his upgrade, he goes from impatient and arrogant to a full-blown supervillain.
  • Evil Brit: Corey Burton uses a more synthesized version of his Megatron voice for Malware.
  • Evil Gloating: It's very, very frequent. It's also the reason he loses his first on-screen fight in the series, as he gloated long enough to allow Ben to transform into Feedback. Though in "Malefactor", he seems to be breaking out of this.
  • Evil Sounds Deep: A deep voice that reflects the sheer animosity it has to all living things.
  • Eye Beams: Just like all Mechamorphs, he is able to project a large ray from his eye.
  • Fatal Flaw: His pride and tendency to talk on and on has gotten him in trouble. He grew out of them, though the former still cropped up from time to time.
  • Fisher King: His end goal in "Showdown" was to send parts of him everywhere on Galvan Prime to corrupt it, eventually allowing him to merge with the planet and become essentially this. Blukic and Driba luckily manage to secure the core before he can reach it.
  • Foreshadowing: "I'd like nothing better than to drain you to an empty shell." He says in a flashback to Ben as Feedback, hinting at would he would eventually do to that form in particular.
    • Ben's present-day reaction to seeing Malware is similarly foreboding, his voice trembling as Malware warns, "You know what I'm capable of." He's referring to when he ripped Feedback out of the Omnitrix and permanently destroyed Ben's access to him.
  • For the Evulz: His main reason for destroying Ben's Feedback form.
  • From a Single Cell: He can regenerate from any injury. Which is why he needed to be Taken for Granite to be stopped for good.
  • From Nobody to Nightmare: He went from a corrupt Galvanic Mechamorph to being able to threaten all of Galvan Prime. As well as becoming a major enemy of Ben, and one of the few to durably scar him.
  • Genius Bruiser: He is incredibly intelligent, a competent schemer, and perfectly capable of holding his own in a fight.
  • Gone Horribly Wrong: The Galvanic Mechamorphs as a whole were an unexpected but positive benefit of a life-giving experiment on Galvan Prime's moon. Malware is the same, but corrupted, absorbing and destroying technology instead of improving it. Then there was the attempt to destroy him, which just made him more dangerous.
  • Good Colors, Evil Colors: Red and black, in contrast to the other Galvanic Mechamorphs' usual green and black. He was originally Yellow and Black to signify his "sickness".
  • Greater-Scope Villain: His presence in the first arc is mostly to direct Psychobos and Khyber, afterwards he's far more direct.
  • Hair-Trigger Temper: Explicitly described by Azmuth as "volatile", this is what makes Malware terrifying as there is no way of knowing what will set him off on a homicidal rage.
  • The Heavy: For the first two seasons of Omniverse. While he was part of the Faction Terrible Trio, where they mostly had equal say, Malware still poses the biggest threat and it is his vendetta against Ben and Azmuth which drives the conflict. He also serves as the final threat that needs to be dispatched after Psychobos had been defeated and Khyber had bailed.
  • Hero Killer: Literally; he ripped Feedback out of Ben and destroyed the form, leaving Ben unable to use him again.
  • Hypocritical Humor: He tells Albedo to shut up due to finding his ego annoying. Malware himself, once being upgraded, never once stops talking about himself and how he is the perfect being.
  • I Am a Humanitarian: A G-Rated version of the trope. Malware can feed on other Mechamorphs, but rather than killing them, it turns them into stone, a condition shown to be reversible.
  • Implacable Man: He nearly rivals Vilgax in this regard. The amount of damage he's survived throughout his arc is astounding.
  • Inferiority Superiority Complex: Despite all of his talk about being the perfect being, he feels that he's Azmuth's failure, even though Azmuth denies it. His entire Boomerang Bigot attitude toward his kind really is a way for him to cope with the fact Azmuth perceives him as flawed.
  • It's All About Me: Best shown by his reaction to Ben telling him that Azmuth was trying to save the Mechamorphs he drained, whinging about how of course Azmuth would save his "Perfect Creations". Never mind that Azmuth himself admits that the Mechamorphs were a happy accident he never intended on creating and that he's trying to save the thousands of Mechamorphs Malware drained of energy. All that matters to Malware is that Azmuth isn't focusing entirely on him.
    • His rant to Azmuth in "Showdown" can be summed up as "My life sucks, it's all your fault, you never gave a damn about me, and even now you're against me."
  • It's Personal: We don't know what, but Present!Ben is noticeably enraged when they meet up again and their words imply something of this nature happened last time they met. It's later revealed that Malware destroyed Ben's Feedback form, and Ben subsequently overloaded and nearly destroyed him with the Omnitrix. Though considering everything else Malware had done, this seems to have just been the straw that broke the camel's back.
  • The Juggernaut: In his One-Winged Angel form.
  • Karmic Death: He ends up Taken for Granite just like all the Galvanic Mechamorphs he fed on.
  • Kick the Dog: He destroyed Ben's Feedback transformation solely for the sake of hurting Ben by obliterating Feedback (his favorite alien).
  • Knight of Cerebus: While his origin episode did have an amount of humor to it, later episodes involving him are played much more seriously. By now, he, Kundo, the Rooters, and Maltruant are the villains who have been taken the most seriously in all of Omniverse.
  • Know When to Fold 'Em: He seems to have developed a habit of this after his first fight with Ben, as he is implied to have retreated in "Of Predators and Prey", and when Ben meets him again in the present day in "Malefactor", he simply decides to distract Ben, and leave from there.
  • Lack of Empathy: Malware cares only for himself. Anything else is no different from an insect as far as he's concerned.
  • Put the "Laughter" in "Slaughter": The chortle he let out while gearing up the assimilated Tachyon cannon against the Tennyson's and inadvertently a small chunk of humankind was particularly bone-chilling.
  • Large Ham: As his quote indicates, he can be quite bombastic at times.
  • Laser Blade: When he absorbs the Proto-Tool.
  • Lean and Mean: He was this before his upgrade.
  • Leitmotif: Has one that plays whenever he shows up.
  • Lightning Bruiser: In both past and present forms.
  • Make My Monster Grow: He grows to be as big as Way Big during "Showdown". And after absorbing all his feelers, he grows to a form larger than Way Big.
  • Man Behind the Man: He was the one who provided Dr. Psychobos with the Omnitrix's blueprint so he could create the Nemetrix as part of an agreement between them.
  • Meaningful Name: Justified; according to him, Azmuth named him that way due to his condition.
  • Names to Run Away from Really Fast: "Malware" is the name for a variety of virus. This might not sound that scary at first, but when you realize he is from a species of sentient machines, that would imply he is named after their equivalent of a plague.
  • New Powers as the Plot Demands: A running theme was that his powers kept developing over the course of the season. His first appearance showcased his traditional Mechamorph powers (Eye Beams stretchy arms), his origin episode displayed his signature ability to absorb tech, "Malefactor" gave him the ability to download computer data and showed he was able to regenerate from being blown apart, And "Showdown" gave him the ability to rip Ben's aliens out of the Omnitrix and apparently corrupt an entire planet.
  • Nigh-Invulnerability: Fire blasts barely faze him, Laser blasts go right through him, being blown to pieces doesn't bother him. Even being overloaded and exploding didn't kill him, but apparently put him out of commission for some time.
  • Nightmare Fuel: In-Universe for Ben and Azmuth.
  • Non-Standard Character Design: Even before his various upgrades, he's more angular than other Galvanic Mechamorphs, lacks the "underbelly" common to them, the markings on his body are much more like tattoos than something computer-like, as well as having a "mouth".
  • Not Quite Dead: Ben overloaded him with the Omnitrix, causing him to explode. Even Azmuth believed him dead until he returned in the present. And at the end of "Malgax Attacks" it seems he's still alive in some capacity...
  • Not-So-Harmless Villain: His first two appearances apparently established as what appears to be a one-off villain with comedic flaws; his following appearances work to build up his establishment as one of the most dangerous villains, as well as the real Big Bad of season 1.
  • Obliviously Evil: He sees himself as a visionary rather than evil.
  • Obviously Evil: Let's see: Red and black skin? Check. Tendencies to deliver long bombastic tirades about himself? Check. Traumatized the protagonist when he was a kid for the sole sake of screwing with him? Check. Dangerously psychopathic? Check. At no point could this guy pass for a good guy.
  • One-Winged Angel: Gradually does this over the course of "Showdown, Part 2", growing from Way Big-sized to a form even more monstrous and taller than Way Big.
  • Our Vampires Are Different: A Galvanic Mechomorph version and just as terrifying as his flesh-and-blood counterparts, if not more so.
  • Powered Armor: He ends up becoming this for Vilgax in "Malgax Attacks". After the whole thing is done, however, something black and red begins leaking out of the defeated Vilgax...
  • Power Copying: Instead of upgrading technology like other Galvanic Mechamorphs, he absorbs it (destroying it in the process) and take their abilities to upgrade himself.
  • Power Nullifier: He is the second villain to be able to do this to Ben, though he seems to do it much, much more forcefully and painfully than Vilgax did. It is later revealed that he did this to create a blueprint of the Omnitrix.
    • And if his ability to pull out and destroy Feedback is to be believed, he can do so much more than just that.
  • Predecessor Villain: In juxtaposing past and present events, he appeared to be a Big Bad to 11-year old Ben, suggesting that he was a predecessor to Khyber for 16-year old Ben.
    • "Of Predators and Prey, Part 1" reveals that he is the reason Khyber is after 16-year old Ben, and that he is still the Big Bad all along.
  • Psychopathic Manchild: Deep down, Malware is basically a big child throwing a tantrum, with major father-son issues toward Azmuth.
  • Recurring Element:
    • He's a twisted and evil version of one of the original 10 Omnitrix aliens who irrationally blames Ben for all the suffering the device has caused him, just like Z'Skayr and Albedo before him.
    • He's a major villain with the power to absorb matter and energy, something every Ben 10 show prior had at least once(Kevin 11 in the original, Morningstar/Darkstar in Alien Force, Aggregor(then Ultimate Kevin) in Ultimate Alien)
  • Red and Black and Evil All Over: he started out as black and yellow, but became this after his upgrade.
  • Redemption Rejection: Azmuth makes one last attempt to reason with Malware by promising to cure him. Malware doesn't buy it.
  • Red Oni, Blue Oni: He is the Red to Dr. Psychobos' Blue.
  • Shock and Awe: He can fire electric blasts.
  • Shout-Out: His final form is basically Ultraman Belial. Fitting, as it debuts against Way Big, who's an Ultraman Expy.
  • The Sociopath: Homicidal, inclined to devastating wrath, self-obssessed and more than willing to throw a gasoline truck at a busload of innocent civilians just to escape from Ben. Ben explicitly describes him to Rook as "a complete psychopath".
  • Spikes of Villainy: In his present form.
  • Taken for Granite: What happens to the unfortunate Galvanic Mechamorphs he feeds on. Also his final fate.
  • This Cannot Be!: When he sees the revived Mechamorphs raining down on him, returning him to normal size. Also when Ben is able to turn into Feedback, a form he destroyed 5 years ago.
  • Unexplained Recovery: Though it can be attributed to his regenerative abilities, it's never been revealed how Malware survived being overloaded by the Omnitrix.
  • The Unfettered: Malware never shows any hesitation or regret in his actions, no matter how many innocents suffer as collateral damage.
  • Vile Villain, Saccharine Show: Omniverse is a much more Lighter and Softer iteration than Alien Force and Ultimate Alien, which makes it very jarring to encounter a villain as murderous and psychopathic as Malware. He murdered people of his own species, used Phil as an unwilling test subject for the Nemetrix, destroyed Ben's Feedback form out of sheer spite (emotionally scarring him in the process), and destroyed his own homeworld. The only villain who could probably match Malware for sheer evil is Aggregor and he only appeared for half of the season.
  • Villainous Breakdown: A very gradual in "Showdown Part 2". He starts losing his cool when Azmuth acts unimpressed by him blowing up Galvan B and starts going on a rampage. Then, when Blukic and Driba manage to stop him from corrupting Galvan Prime's core, he snaps, goes One-Winged Angel, and tries to absorb Ben in retaliation. Finally, the revived Mechamorphs rain down on him, returning him to normal size. His plans ruined, he makes one final attempt to kill Ben out of spite, only to be easily defeated.
    Malware: CURSE YOU, BEN TENNYSON!
  • Villainous Demotivator: To Khyber at the end of "Of Predators and Prey".
  • The Virus: Considering his powers, it wouldn't be a stretch to call him one. Fittingly, the word Virus is used as his name in the French dub.
  • Visionary Villain: He describes himself as one.
  • Vocal Evolution: His first few appearances utilized a quieter computer-like monotone voice which had a heavy digital filter. His later appearances tone down the monotone voice and digital filter and instead give him a much louder and scratchier psychopathic voice.
  • Walking Spoiler: His whole history drives most of his arc and the tropes covered are his history in general.
  • "Well Done, Son" Guy: If his rant to Azmuth in "Showdown" is any indication, he always resented Azmuth for never recognizing him as his perfect creation.
    Malware: No! Nothing I do could ever impress you could it "Father?!" In your eyes, I am nothing but your failed experiment! Your shame!
  • Where I Was Born and Razed: Helps Dr. Psychobos destroy his home planet. Considering his opinion of the rest of his kind, Psychobos probably didn't need to twist his arm to make him do it either.
  • Would Hurt a Child: He is perfectly willing to kill innocent children to escape from Ben.
  • You Have Failed Me/You Have Outlived Your Usefulness: attempt to do this to Khyber in "Outbreak", but Dr. Psychobos stops him.

    Dr. Psychobos 

Dr. Psychobos

https://static.tvtropes.org/pmwiki/pub/images/Of_Predator_part1_48_113.png
Voiced by: Eric Bauza
"Honestly, Galvan and their superiority complex. Dullards! The lot of them... especially that imbecile Azmuth! This will finally prove, once and for all, that Cerebrocrustacean are smarter than Galvan, and that I, personally, am far superior to that arrogant amphibian!"

A Cerebrocrustacean (Brainstorm's species) scientist who is responsible for the creation of Khyber's Nemetrix. Dr. Psychobos has a strong despise of the Galvan species as a whole, and especially Azmuth, who he has a personal rivalry with (though Azmuth apparently doesn't care). In an attempt to prove his species are the smartest in the universe, he teamed up with Malware in order to get the Omnitrix blueprints, so he could then use it to create his own, superior version of the Omnitrix. This resulted in the Nemetrix, a feral version of the device that could only work on creatures of limited intelligence. He and Malware then proceeded to hire Khyber to collect the DNA required to make it work.


  • Affably Evil: At least in his interaction with Malware.
  • Always Second Best: Based on what Maltruant said, Dr. Psychobos is the second smartest being in the Universe right behind Azmuth.
  • Badass Bookworm: He is apparently the second smartest scientist in the Ben 10 Universe and has shown a few times he is quite capable of defending himself.
  • Bad Boss: Along with Malware, he threatens Khyber on occasion. The next time he did this in "Showdown, Part 1" to the point of attempting to Mind Rape him when Khyber refuses to obey. This bit him in the arse when Khyber decided to just leave him be when Azmuth showed Psychobos' natural predator.
    • To be fair though, he was on the other end of this trope with Malware
  • The Bad Guy Wins: A minor example, but "Outbreak" ends with him getting what he wanted (a piece of the Omnitrix). Not only that, but he did it incredibly easily; it took him a few minutes to get it.
  • Berserk Button: Saying that Galvans are smarter than Cerebrocrustacean's. Blukic and Driba told him that the dumbest Galvan was still smarter than the most intelligent Cerebrocrustacean and he went totally ballistic.
  • Beware the Silly Ones: Psychobos is simultaneously the silliest but also the nastiest out of the Faction. For one he's the mastermind of the Nemetrix plot and the Azmuth assassination attempt. Along with the fact he's a Mad Scientist who has been responsible for some of the more horrible human/alien experiments seen in the series, with him mutating Bill into an Artificial Hybrid that is played up as straight Body Horror, as well as genetically engineering the mutated Way Bads when they are typically peaceful creatures.
  • Big Bad Duumvirate: He has had a number of villainous partnerships over the series.
    • In the Nemetrix arc he joins forces with Malware and Khyber, in a bid to take down both Azmuth and Ben Tennyson.
    • He gets recruited by Princess Attea though he seems to have been Demoted to Dragon and serves as her underling.
    • Maltruant also hires him for his services in repairing him.
  • Big Bad Wannabe: He talks a big talk, but he clearly doesn't even come close to any of his temporary allies in terms of threat-level. Azmuth barely considers him a rival even when his life was in danger.
  • Bond Villain Stupidity: He did not recognize the threat Ben posed to Malware's plan. Even Malware calls him out on it at the end of "Outbreak".
  • Butt-Monkey: To Attea once he has been Demoted to Dragon.
  • The Cameo: It's a blink-and-you'll-miss moment, but he makes an appearance in "Special Delivery" during Psyphon's auction.
  • Character Catchphrase: "(random appellation) -and I use the term loosely."
  • Crouching Moron, Hidden Badass: His first appearance depicts him as a standard Mad Scientist whose motivation is petty jealousy toward Azmuth with mild manners and a Verbal Tic, making him look rather like a comedic villain compared to Malware or Khyber. In "Outbreak", however, he easily brings down both of them when they are arguing before raiding the Plumbers' HQ and successfully stealing a piece of the Omnitrix from Ben.
  • Cyborg: His psionic powers are augmented by the devices attached to his brain.
  • Demoted to Dragon: After Malware's defeat, he now serves Princess Attea.
  • Didn't Think This Through: He managed to keep Azmuth from teleporting out, but didn't stop him from teleporting Ben in.
  • Enemy Mine: He teams up with Ben and Ben 23 to escape from Mad Ben, and repairs their Omnitrixes. He double-crosses them of course by rigging the Omnitrixes to explode if they transformed into Clockwork and Upgrade, but then the Bens undo it by transforming into Grey Matter/Brain Frog.
  • Evil Counterpart: To Azmuth, with both being genius scientists and the first and second smartest minds in the universe respectively. Though the two are opposite sides of the moral spectrum, with Azmuth being the Big Good while Psychobos is a Mad Scientist who constantly forms villainous partnerships.
  • Evil Genius: He's the main Mad Scientist for hire in Omniverse. To his frustration no matter what he does his evil genius will always be second to the Galvan race.
  • Ex-Big Bad: He was part of a Terrible Trio in the Nemetrix arc where they mostly had equal say, with Psychobos slightly calling the shots. But in all subsequent appearances, he is Demoted to Dragon and plays second fiddle to the main villain.
  • Fantastic Racism: He expresses this toward the Galvans, for whom he is trying to prove Cerebrocrustaceans are superior to. Then taken to horrible extremes when he actually develops a plan to eradicate their species from the galaxy.
    • This seems to be a common trait among Cerebrocrustacreans, as in Alien Force, Ben, as Brainstorm, suggested that he was smarter than Azmuth because his brain was bigger. Respectively, some dialogues from Blukic and Driba suggest that some Galvan are racist toward Cerebrocrustaceans as well (though it may have been at least partially taunting).
  • Giant Enemy Crab: Not as large as most, but big and an antagonist.
  • Hoist by His Own Petard: Azmuth turns the Nemetrix against him by building a whistle to take control of Khyber's pet and make him turn into the Cerebrocrustaceans' natural predator.
  • Humiliation Conga: Defeated by the very thing he created, betrayed by Khyber, and arrested by the same species he despises so much. All in the span of a minute. And to add insult to injury, one of the Galvan arresting him calls him a dummy.
  • Hypocrite: He constantly calls the Galvan arrogant and accuses them of suffering a superiority complex. He considers himself the greatest mind in the entire Universe (whereas Azmuth says he is the greatest mind in three galaxies, arguably five), and his whole motivation centers around proving that his own species is superior to Galvan.
  • Insufferable Genius: He's basically Albedo as a Cerebrocrustacean.
  • Know When to Fold 'Em: In "Outbreak" once he gets the piece of the Omnitrix he wants, he immediately makes a break for it.
  • Mad Scientist: A crazy scientist sick with jealousy of the Galvans, to the point of having very few to no moral scruples in his work.
  • My Brain Is Big: Huge in fact.
  • The Man Behind the Man: He is the one who hired Khyber to go after Ben.
  • Names to Run Away from Really Fast: seriously, with a name like this, how can there be any doubt about him being a Mad Scientist?
  • Non-Action Big Bad: Aside from stealing Ben's stabilizer, he didn't accomplish much for most of the first two story arcs, contenting himself with planning and technical support.
  • Non-Standard Character Design: Dr. Psychobos is blue, has a different body shape than other Cerebrocrustaceans shown, and has one large claw, similar to a fiddler crab. According to Word of God, this is because he is not a typical Cerebrocrustacean.
  • Not-So-Harmless Villain: For most of season 1, he seems to be the least dangerous of the three main villains. Then his plan turns out to involve genocide of all Galvan...
  • Only Sane Man: Between the Big Bad Ensemble of Malware, Khyber, and himself, his only major problem is that he is very smug, but aside from that, he seems to be the sanest of the bunch.
    • Similarly, he is generally more reasonable than Attea and can't stand her bratty outbursts, though he can't do much about it.
  • Power Floats: "Outbreak" shows that he has the ability to hover.
  • Red Oni, Blue Oni: the blue to Malware's red. Even reflected by their colors.
  • Red Right Hand: One of his pincers is much larger than the other.
  • Sesquipedalian Loquaciousness: He is from Brainstorm's species; what did you expect?
  • Shock and Awe: He has technology in his brain that (presumably) increases the strength of his natural electrical powers.
  • Smug Snake: Constantly boasting of his genius to anyone who would listen, but he's not smart as he wishes he was.
  • Starfish Alien: Like most of his race, he is way removed from any humanoid race.
  • The Starscream: To Princess Attea. It's pretty clear he would gladly stab her in the back if he had the occasion. Sadly for him, she keeps an eye on him.
  • Too Dumb to Live: He included his own natural predator in the Nemetrix and expected that not to backfire horribly.
  • Underestimating Badassery: What ultimately leads to his downfall. By not recognizing Ben as a threat to his plans and focusing only on Azmuth, he's unprepared for Azmuth teleporting Ben in to help.
  • Unknown Rival: To Azmuth. He believes Galvans, especially Azmuth, have a big superiority complex and tries to prove that Cerebrocrustaceans are smarter than them. Azmuth, however, thinks that trying to prove who's the smartest is a complete waste of time and energy.
  • Verbal Tic: He tends to stutter on random words.
  • Villain Decay: His first full appearance featured he do something that had him win. Later appearances play up his comical quirks and don't make him terribly threatening. By the time of the Incursean Story arc, he has been mostly reduced to being Attea's Butt-Monkey. He lampshades this in "It's a Mad, Mad, Mad Ben World".
    Dr. Psychobos: So this is what it's come to? The greatest mind in the galaxy reduced to mere tech support?
  • World's Smartest Man: Actually the second smartest being in the universe, the first being Azmuth, which he is very upset about. Psychobos is constantly trying to take the top spot for himself by either defeating or killing Azmuth.

    Khyber the Huntsman 

Khyber

https://static.tvtropes.org/pmwiki/pub/images/Khyber_and_pet_3888.PNG

An alien Egomaniac Hunter who seemed to serve as the main villain in the first season of Omniverse, but was really The Dragon to Malware, the true main antagonist. Khyber is accompanied by an alien dog-like creature known as an Anubian Baskurr which he equips with the "Nemetrix", a device similar to the Omnitrix that allows his pet to turn into various predatory species. He went to Earth following rumors about Ben's heroic acts and sees the boy as a worthy prey to add to his trophies.


  • Awesome Aussie: He has a thick Australian accent to go along with his hunting persona.
  • Affably Evil: He is quiet and polite in addition to having a sense of honor. However, he will not hesitate to add your head to his trophy collection if you're his prey.
  • Arc Villain: Of the first story arc. He's later revealed to be acting as The Heavy to Malware.
  • Badass Boast: "Choose wisely, Tennyson. Whichever alien you pick, will be your last!"
  • Badass Normal: Aside from some odd bits of physiology like gills and maybe slight Super-Strength, he has no obvious superpowers. Word of God compares him to Vilgax as Captain America is to Thanos. Yet he's able to go toe to toe with some of Ben's more powerful aliens like Rath.
  • The Beastmaster: Has a dog whom he tamed to an extent.
  • Benevolent Boss: Zig-zagged; On one hand, he treats both of his pets kindly, complimenting and comforting them, refers to them as "friends", and gets irritated when they are mocked. On the other hand, he never feeds them himself and instead forces them to hunt for their own food so they will keep their hunting instincts, doesn't bother giving them names, and has no problem leaving Zed behind after taking the Nemetrix when he escapes. Seems to be a major case of Blue-and-Orange Morality.
  • Berserk Button: He doesn't take belittling his skills or his pet kindly.
  • Big Bad Duumvirate:
    • With Malware and Psychobos for the Nemetrix arcs, with Khyber as The Heavy in the first season.
    • With Albedo for the Duel of the Duplicates.
  • The Bus Came Back: He disappears from the Season Two finale, escaping with the Nemetrix and was not brought up again afterward. He returns in "The Ultimate Heist", which featured him teaming up with Albedo.
  • Crazy-Prepared: The flashback sequence that features him hunting the predators for the Nemetrix portrays him as this. He seems to have equipment specifically built to face each one of them.
  • The Dog Bites Back: He leaves Psychobos to be arrested by the Galvans as revenge for the scientist trying to Mind Rape him into fighting Azmuth instead of Ben. He then disappears with the Nemetrix without a word. Moreover, he doesn't even bother to take Ben away.
  • The Dragon: First to Malware.
    • Dragon with an Agenda It's suggested that Khyber either doesn't trust Malware or has plans of his own. He is shown in an episode infiltrating the Plumbers' Headquarters to get information about Malware's origins and motivations, suggesting he is trying to inform himself on his hirers. Later, "Outbreak" makes it quite clear that, while Malware and Psychobos are primarily interesting in getting their Omnitrix and besting Azmuth, he is only concerned with getting Ben as a trophy and doesn't really care about their goal. He also partially tells Rook about Malware's plan in "Malefactor", saying he "has his reasons" for such a revelation. This plays against both of them when an assassination attempt on Azmuth fails because Khyber wants to focus on Ben.
      • Don't forget that he included Dr. Psychobos' natural predator in the Nemetrix. It seems the guy never seemed to fully trust anyone but himself. But to be fair, that was also Brainstorm's natural predator, so if Ben ever transformed into Brainstorm...
    • He became the Dragon to Albedo in the fourth story arc.
  • Drill Sergeant Nasty: While he didn't bother feeding Zed when she was his pet, it wasn't out of egotism or cruelty. He merely believed that, by forcing her to hunt her own food, that would allow her to keep her hunting instincts and make her more effective.
  • Egomaniac Hunter: He is one in a very Predator-like way, he apparently likes to hunt down various alien creatures and keeps trophies of them. He precisely goes after Ben because he considers him a "Worthy Prey".
  • Evil Counterpart:
    • Of Ben to an extent. His Nemetrix is described by the producers as a kind of "Evil Omnitrix".
    • In a way, he's a more fitting counterpart to Rook. They are both extremely skilled Badass Normals, act as Hypercompetent Sidekicks to their egotistical and somewhat narcissistic bosses (this goes for both Psychobos and Albedo), and both work with partners that rely on biological powers and shapeshifting while he and Rook use wit and cunning to win fights. Plus, their relationships with their counterparts are reversed: Khyber is the master and treats his pet well and respects it, while Ben is Rook's superior officer and openly argues with him.
  • Expy: He's basically an alien version of Kraven the Hunter, being a hunter who views a superhero as worthy prey. He also shares similarities with the Predator, and to an extent, Lockdown and Airachnid.
  • Genius Bruiser: An extremely skilled hunter and fighter, with an eye for catching and taking wild animals.
  • The Heavy: He was the main threat of the Nemetrix arc, as Psychobos remained behind the scenes for the most while Malware was mainly the flashback villain and remained inactive for most of the present.
  • Hunting the Most Dangerous Game: Hunting the most dangerous game: Ben Tennyson.
  • Karma Houdini: Malware is defeated, Psychobos is arrested, but Khyber still remains at large.
    • He also escapes after Albedo is defeated, but this time he loses the Nemetrix.
    • It's finally averted after he's defeated as Tyrannopede.
  • Hypocrite: In "For A Few Brains More", Khyber calls Zed a "traitorous cur" for being with Kevin despite the fact that he abandoned her. Technically, Zed betrayed him first, as Ben found a way to turn her against him.
  • Idiot Ball: If he didn't freak out upon seeing Pesky Dust, the heroes wouldn't have had any hint where to look for Albedo and Ben would have continued thinking Pesky Dust was totally useless.
  • Knight of Cerebus: He is the first major villain in Omniverse to not be played for laughs, combined with the fact he is hell-bent on killing Ben and will hunt him to the ends of the Earth.
  • Know When to Fold 'Em: He calls off his pet when he sees Rook helping Ben, acknowledging his pet being outnumbered.
  • Leitmotif: A quiet, creepy theme plays whenever he is in his ship.
  • Out-of-Character Moment: At one point during "Of Predators and Prey: Part 2", when it appears that he's been captured, he joins in Rook and Ben's small scuffle about Rook usually having to save Ben's life rather briefly, dropping the less humorous qualities of the character for just a few seconds. It turns out he was faking submission to better surprise them.
  • The Only One Allowed to Defeat You: Towards Ben. Since he planned to take Ben as his trophy, he will not let anyone but him to slay him, to the point of sending his pet to interfere, as Psyphon and Animo found out. This later puts him at odds with his employers as he put his goal to make Ben a trophy before his mission.
  • Psycho for Hire: To Malware and Psychobos. Yes, he is Affably Evil, but he is still technically a Serial Killer.
  • The Stoic: Geberalky reacts to everything with a dull look.
    • Not So Stoic: Despite his usually quiet attitude, he's quickly irritated when Ben mocks and taunts him. He's also not above a back and forth "Rath Season", "Khyber Season" quip-off.
  • Serial Killer: Most of his trophies are sentient alien species, essentially making him an alien version of this.
  • Skeletons in the Coat Closet: Word of God is that his torso armor is made from the bones of some of his previous targets.
  • Spikes of Villainy: Has spikes on his outfit.
  • Trophy Room: His whole ship is a trophy room. Among his prizes are a Vulpimancer-skin rug, a Geochelone Aerio shell, an Appoplexian skeleton, and a Crabdozer head.
  • Villain Decay: He never quite regains the danger he posed in the first two arcs via being humiliated in a later arc. His last appearance "Stuck on You" brings back some of his intimidation factor, though he makes a major mistake in judgment in trusting Skurd, who latches himself to Ben's Omnitrix due to containing more DNA.
  • Villain Has a Point: You can't really disagree with him when he points out how Ben should treat his partners better.
  • Villain Team-Up: In "The Ultimate Heist", he works with Albedo.
  • Weaksauce Weakness: He's afraid of Nemuinas (Pesky Dust's species).
  • What Happened to the Mouse?: He completely disappears from the story after "Showdown: Part 1", and hasn't been mentioned since.
    • He's back in "The Ultimate Heist.", now working with Albedo.
  • Worthy Opponent: How he sees Ben, though more like "Worthy Prey".
    "I am the Ultimate Predator. You are the Ultimate Prey."
  • You Have Failed Me: A notable Aversion; he never punishes his pet for failure to get Ben, and will usually even comfort it.

Khyber's New Pet

https://static.tvtropes.org/pmwiki/pub/images/pnunsian_6271.png

After abandoning his previous pet, Khyber obtained a new pet. It is a Panuncian from the planet Hathor, the homeworld of Ditto's species, the Splixsons, and is their natural predator.


Arc Villains

    The Rooters 

The Rooters

https://static.tvtropes.org/pmwiki/pub/images/the_rooters.png
From left to right: Phil Billings, Swift, Servantis and Leander

The secret Black Ops branch of the Null Void Plumbers who went rogue.


Tropes applying to the group as a whole:

  • Arc Villain: Of the sixth story arc in Omniverse.
  • Artificial Hybrid: They all are former humans who gained alien characteristics from experimenting on Kevin when he was in the Null Void.
    • Proctor Servantis: Human/Cerebrocrustacean (Brainstorm's species)
    • Agent Swift: Human/Aerophibian (Jetray's species)
    • Magister Leander: Human/Prypiatosian-B (NRG's species)
    • Phil Billings: Human/Terroranchula
  • Dark Is Evil/Evil Wears Black: Their uniforms are a black Palette Swap of Rook's Proto-Tech Armor. They tested the design in the Null Void before it made its way to the Plumbers.
  • Hypocrite: They believe Ben needs to die on the basis that so much power shouldn't be in the hands of an immature, irresponsible child. Their master plan to reach this goal involves giving alien-based superpowers to several random kids they collected, which they eventually left running on Earth with no control. And to add to the hypocrisy, this little hit squad was led by Kevin, a superpowered kid who already had a criminal record back then and whose ability specifically causes him to turn psychotic whenever he gets in contact with the Omnitrix. For people so concerned about killing a child for being dangerous, they sure are good at creating more dangerous superpowered kids. Word of God is they were responsible for creating Aggregor as well, someone massively more dangerous than Ben ever could be, making them look even more hypocritical if possible.
  • Ironic Hell: They are punished for their actions by having their status as Plumbers revoked and being left in the Null Void, their base of operations... after the Plumbers beam out everything but the clothes on their backs.
  • Knight of Cerebus: The first major Omniverse villains since Malware to significantly change the tone of the episode they first appeared in, where the Plumbers are clearly uncomfortable with dealing with them and their ties to Kevin, Argit, and the Plumbers' Helpers.
  • Murder Is the Best Solution: They really don't need to kill Ben to accomplish their goal, seeing how Ben is a harmless kid without the Omnitrix, just taking it away from it and destroying it would be sufficient. Yet, they decide it's best to eliminate both him and the Omnitrix.
  • Obviously Evil: The Rooters are so transparently sinister that, despite ostensibly being on the same side and answering to the same authority, the Plumbers immediately resolve to oppose them as thoroughly as they believe they can get away with.
  • Red Eyes, Take Warning: All of them are antagonists with red eyes except for Phil, when he's not in his Terroranchula hybrid form.
  • Renegade Splinter Faction: They are an offshoot of the Plumbers, founded by a former Plumber scientist, Proctor Servantis. They eventually lose their Plumber support and HQ.
  • Token Human: Phil Billings is the only member whose alien characteristics are only shown when transforming.
  • Vagueness Is Coming: They warn of some existential threat that only they have the means to stop. Ben and Max are pretty convinced it's a load of bull so they can keep experimenting on aliens. It's then revealed that Ben is the threat, on the logic that his power is too great for him alone to possess. The Amalgam Kids were created to destroy him.
  • Villain Ball: In their first appearance, they could probably have easily acquired the Plumbers' help if they had just given a fake good reason why they are looking for Kevin and kept a benevolent facade. Instead, they show up without warning, act all suspicious and arrogant, ask where Kevin is without explaining anything, and Servantis proceeds to painfully Mind Probe almost every Plumber recruit around for information without even giving them a chance to answer normally first. As a result, the Plumbers do everything they can to disturb their efforts and eventually turn against them.
  • Well-Intentioned Extremist: Zig-Zagged. They do make a legitimate argument about questioning the wisdom of letting a kid wield a watch that can turn him into anything from a skyscraper-sized alien to a being who literally recreated the universe. The problem is their methods are far from what you would call moral. In addition, the whole premise behind their methods is the idea Ben might become a threat to the universe, not is a threat. The fact they apparently created Aggregor and just let him loose on the universe, really undermines any point they have by their sheer irresponsibility.
  • Would Hurt a Child: The Rooters considered killing Ben a necessity for creating a safe and better universe.

Servantis

https://static.tvtropes.org/pmwiki/pub/images/proctor_servantis.png
Voiced by: Charlie Adler

The leader of the Rooters.


  • Amplifier Artifact: The crystal on his forehead amplifies his Cerebrocrustacean abilities. When Kevin destroys it he loses his mind control over the Plumber's kids.
  • Bald of Evil: Even when he was human, he had not a single hair on his head and was a villainous soul to match.
  • Beard of Evil: Has a goatee, both as a human and an evil Artificial Hybrid.
  • Big Bad: The leader of the Rooters in their Story Arc.
  • Bond Villain Stupidity: He and the other Rooters had Ben as their prisoner in "The Rooters of All Evil" and could have easily ended all of this by just killing him right now, as pointed out by Swift, but Servantis instead decides to let him go and stick to their ridiculously complicated plan on the justification that "He is tougher than he looks". Even though at this point, Ben was unconscious, their prisoner and in human form, meaning they could have killed him with just one blast and then disposed of the body and the Omnitrix.
  • Complexity Addiction: He's insisting on sticking to his ludicrously complicated plan over something more simple and practical.
  • Expy: He is also rather similar in appearance to the Transformers: Animated Decepticon Mindwipe, who had the power of hypnosis.
    • His role as a former galactic peacekeeper gone rogue bares some similarities to Sinestro. He looks a bit like Sinestro in his alien form.
  • Faux Affably Evil: He behaves in a polite way even when using his painful Cerebrocrustacean powers on Plumbers to get what he wants and has no problem using children as test subjects.
  • Greater-Scope Villain: Aggregor was acting on his own, as Servantis wiped his memory before setting him loose, but as his creator, he is indirectly responsible for Aggregor's actions.
  • Laser-Guided Amnesia: He inflicted this on Kevin, Argit, Max and all the Plumber's Helpers.
  • Lean and Mean: The thinnest Rooter, and the leader who experimented on children so that they could kill Ben.
  • Mad Scientist: He experiments on children in order to create alien-powered super-soldiers.
  • Manipulative Bastard: Even without his powers, he has a very persuasive effect on people's minds.
  • Mind Control: He used his powers to force Zed into submission. He also mind controlled the Plumber's helpers until Kevin destroyed the crystal on his forehead.
  • Mind over Matter: In a flashback he sent a tank flying out of anger.
  • Mind Probe / Mind Rape: He can use his part-Cerebrocrustacean powers to read minds. The process is uncomfortable at best, and painful at worst (with Servantis claiming that struggling can cause severe damage).
  • My Brain Is Big: His half-Cerebrocrustacean body gives Servantis a very large forehead to contain his big brain.
  • No Man Should Have This Power: He feels that something as powerful as the Omnitrix should not be in the possession of someone as unpredictable and immature as Ben
  • No-Sell: While he can alter Kevin's memories, he cannot read or control his mind.
  • The Sociopath: He has no consideration for anyone as fellow life forms, but as things to either use or destroy.
  • Suspiciously Similar Substitute: He is a rather blatant one of Driscoll, down to looking the same before his transformation into a Cerebrocrustacean hybrid.
  • Telepathy: In addition to his single target Mind Probe, he can read surface thoughts within a certain range.

Swift

https://static.tvtropes.org/pmwiki/pub/images/swift_character_1142.png
Voiced by Tara Strong

An Aerophibian Rooter.


Leander

A Prypiatosian-B Rooter.


  • Energy Weapon: Unlike Swift, he can only shoot them from his face.
  • Eye Beams: His signature ability.
  • Shout-Out: The way he has to press his fingers to the side of his head to fire is similar to Cyclops from the X-Men.
  • Silent Antagonist: He never says a word during his appearances. According to Word of God, he's mute.

    Evil Alternate Bens 

Evil Bens

Voiced by: Yuri Lowenthal

Alternate Bens that Vilgax and Eon worked to corrupt to have their own army of Omnitrix-wielders.


In general:

  • All There in the Script: Almost all of them, sans Eon, Albedo and Mad Ben, are unnamed in the show, but can be found online.
  • Evil Counterpart/Evil Twin: Due to all of them being evil versions of Ben Tennyson, with Bad Ben having most of it. Amusingly, Albedo is among them as well.
  • Fallen Hero: What some of them are bound to be, due to Vilgax and Eon corrupting them. Eon himself is also an alternate Ben.
  • Flat Character: They aren't very well-defined as characters beyond aesthetic and personality traits to keep them identifiable. Mad Ben is the sole exception, being the focus of a two-parter at the end of Omniverse's seventh arc.
  • Palette Swap: They all have different color themes among them, which carry over to the Alien they transform into. Most, however, have surprisingly distinct appearances, with only two of them really using Ben's normal design, just modified (Bad Ben has black hair and an aqua theme, while Nega Ben wears Ben's hoodie, just pulled over and covering his right eye, with his color theme being gray). Mad Ben's aliens avert this, having distinct appearances from Ben's.
  • Weak-Willed: The reason Vilgax and Eon were able to corrupt them.

Bad Ben

https://static.tvtropes.org/pmwiki/pub/images/bad_ben_7976.png

The first evil alternate Ben to be introduced. He is the first to find No Watch Ben and attack him, soon allowing the others to follow.


  • All There in the Manual: What little is known about his background. According to Word of God, his homeworld is one where "everyone is just desperate."
  • Deadpan Snarker: He is the closest to the regular Ben, resulting in him having some of the same wit.
  • Flat Character: Bad Ben is easily the most generic out of all of the Evil Bens. He has no personality or motivation of note, he's evil simply just because. According to Word of God, while the other Evil Bens had some backstory written for them, there is nothing for Bad Ben.
  • I Shall Taunt You: Takes a twisted pleasure in mocking No Watch Ben's surprise and confusion before actually trying to kill him.
    No Watch Ben (after seeing him transform): This is impossible!
    Bad Ben/Ghostfreak: Hardly. Though I realize none of this makes sense from your point of view. If I were a nice guy, I would explain why you must be destroyed... (reveals his Combat Tentacles) But I am not a nice guy!
  • Lack of Empathy: Doesn't have a second thought about killing his alternate self.
  • Palette Swap: All the other alternate versions of Ben seen so far, good or evil, have unique designs with their own features. He on the other hand is identical to mainstream Ben, only with black hair.
  • What Is Evil?: When he and the other evil Ben are referred as such by mainstream Ben, he answers that evil is "relative".

Benzarro

https://static.tvtropes.org/pmwiki/pub/images/benzarro_ben_10_omni_5446.png

An alternate version of Ben from a Zombie Apocalypse timeline.


Nega Ben

https://static.tvtropes.org/pmwiki/pub/images/negaben.png

An alternate version of Ben who appears to be goth.


  • Emo Teen: Appears to be one, given he doesn't care much for what's going on around him, and not even being defeated by No Watch Ben bothered him much. Word of God states that even turning into Rath or Atomix wouldn't change his attitude.
  • In the Hood: Constantly seen wearing a hood.
  • Not as You Know Them: His entire universe is this compared to the rest. Aside from Nega Ben being emo, Nega Gwen is a cheerleader, and Nega Kevin is a Surfer Dude.
  • Not So Stoic: He soils himself as Gutrot when he sees the Chronosapien Time Bomb's explosion right in his face.
  • Token Good Teammate: Of the evil alternate Bens. Word of God says that Nega Ben literally does nothing with his Negatrix, not for personal gain, nor for fighting villains. He's more or less just a neutral character, seemingly only in the conflict out of boredom.

Mad Ben

https://static.tvtropes.org/pmwiki/pub/images/mad_ben_7180.png

An alternate version of Ben who used the Omnitrix to enslave and seize power rather than become a hero. He is a tyrant and warlord in his dimension.


  • Anime Hair: A very Apunkalyptic pompadour.
  • Arc Villain: The main antagonist of the seventh story arc, as Ben Prime and Ben 23 are stranded in his world.
  • Ascended Extra: He goes from one of the minions to Vilgax and Eon to becoming an Arc Villain for Arc 7 in "It's a Mad...Ben World" two-parter.
  • Borrowed Catchphrase: He uses Dr. Psychobos' "...And I use the term loosely" when mocking him.
  • The Dragon: To Maltruant.
  • Egopolis: He renamed the destroyed Bellwood "Benwood".
  • Evil Mentor: According to himself, he was taught everything he knows by Maltruant and "Vilgax the Benevolent".
  • Evil Overlord: He rules as the tyrant of his dimension.
  • The Heavy: For Maltruant, who uses him to keep Ben Prime and Ben 23 at bay while he completes his plans.
  • I Take Offense to That Last One: When his Rook turns against him and calls him a "petty, little thug", it's the "little" that really ticks him off.
  • No Kill like Overkill: He transforms into Way Big in an attempt to crush Ben Prime and Ben 23.
  • Red Eyes, Take Warning: They're orange, but it's close enough.
  • Shout-Out: His design sensibilities are based upon Mad Max.
  • Spikes of Villainy: In keeping with his Mad Max theme, both his human and alien forms have very spiky designs.
  • Unwitting Pawn: Maltruant used Mad Ben to recover his key, then left Mad Ben to his own devices.
    • And also to Vilgax, who he calls Vilgax the Benevolent. Evidently, the two have been putting bad ideas into his head.

    Maltruant 

Maltruant

https://static.tvtropes.org/pmwiki/pub/images/maltruant_1664.png
Voiced by: Mark Hamill
"I have dreamed for millennia of this moment! An entire universe in my image!"

The antagonist in the Time War arc. He was first mentioned in "Ben Again", and makes his debut at the end of "Fight at the Museum". He is a Chronosapien (Clockwork's species).


  • Beam-O-War: He and Clockwork, who is enhanced by Ben 23's Upgrade, do this. Maltruant wins, disabling their Omnitrixes, proving just how powerful he is.
  • Big Bad: Of the Time War story arc.
  • Card-Carrying Villain: Going by his notion that Azmuth is "too smart to be evil", he's aware that villainy is dumb but doesn't care.
  • Chronic Backstabbing Disorder: He abandoned Mad Ben after he found his key. When Eon brought him a Time Beast-pulled chariot, Maltruant pushed him off, and took the reins, leaving him behind. He even abandoned his most faithful servants, Exo-Skull and Subdora, in his haste to enact his end game strategy.
  • Dark Lord on Life Support: Initially. He has Dr. Psychobos repair him, and regains his powers once the head key is restored.
  • Dismantled MacGuffin: His own body. The first time he was defeated, Professor Paradox took three parts of him that were key to his powers and scattered them across time and space. He manages to find and retrieve them all after getting back on his feet.
  • Fate Worse than Death: He is stuck in a time loop doomed to failure, and he's completely unaware of it.
  • Faux Affably Evil: Personality-wise, he's not as threatening as he looks. He can be quite hammy at times, and he speaks in a pseudo-German accent like Clockwork. Don't be fooled though — he holds nothing back to show that he's a dangerous criminal.
  • Final Boss: He is the last major antagonist in Omniverse and the Classic Ben 10 franchise.
  • Greater-Scope Villain: He is partially the reason Vilgax became interested in the Omnitrix in the first place, as well as the reason Vilgax has a Chronosapien Time Bomb.
  • Hoist by His Own Petard: Ben blasts him to bits with the energy from the very device he was trying to use to remake the universe in his image.
    • Going back to before time existed nullifies his powers.
  • In Their Own Image: His goal was to recreate the universe in his image.
  • Knight of Cerebus: He is far less likely to be played humorously than a lot of Ben's enemies, especially with his ultimate goal of remaking creation in his own image.
  • Lightning Bruiser: With his control over time, he can avoid any attack and take down anyone with one attack simply by freezing them in time.
    • Flash Step: Can make it seem like he's in multiple places.
  • My Species Doth Protest Too Much: Paradox describes him as a "rogue Chronosapien", thus implying that the rest of his species are more respectful of temporal integrity.
  • Narcissist: When presented with the Contumelia, Appearance Is in the Eye of the Beholder beings that appear as the thing you hold most dear, while Ben and Rook see people close to them, Skurd sees masses of energy, he just sees himself.
  • Nigh-Invulnerability: If blown to bits, he'll just eventually rebuild himself. Even Ben blasting him with energy equal to a Big Bang didn't kill him, only blasting him to bits. Thankfully, he's then trapped in a Stable Time Loop.
  • Nothing Can Stop Us Now!: He makes this boast when he's frozen Ben 10,000, Kai, and Gwen. Then Spanner brings in Ben and Rook from the past, causing him to immediately lampshade his error.
  • Red and Black and Evil All Over: Compared to the heroic Clockwork who's golden, he's mostly grey and black with a red glow, and you could definitely assume he's evil.
  • Red Eyes, Take Warning: He glows red instead of green, and is as evil as that suggests.
  • Stable Time Loop: He reassembles himself, tries to remake the universe, Ben defeats him and breaks him apart, and Professor Paradox hides his pieces. The only one unaware of the loop is Maltruant himself.
  • Suspiciously Similar Substitute: It might be unintentional, but fans have noticed he shares similarities with Malware, being from the same species as one of Ben's aliens with a red and black color scheme and a name starting with "Mal".
  • Time Abyss: If the quote above says so then he must've lived for thousands of years.
  • Time Master: He demonstrates great skill in his abilities in actual combat. Can go places even Paradox can't go like the void before the universe was made. However, since the void contains no time, it becomes a non-lethal Kryptonite Factor.
  • Villain Team-Up: He briefly formed one with fellow time-based villain Eon.

Independent Villains

    Psyphon's Gang 
Bubble Helmet voiced by: John DiMaggio
Fistina voiced by: Morgan Lofting
Liam voiced by: Paul Eiding
https://static.tvtropes.org/pmwiki/pub/images/Liam_Fistina_and_Bubble_Helmet_in_Chris_10_3589.png

A gang of alien criminals introduced as Psyphon's henchmen. There are many members focused, few of them getting actual development, but three of them, Liam, Fistina and Bubble Helmet, are frequently seen working together.


  • Abhorrent Admirer: Fistina is this toward Rook.
  • Blade Below the Shoulder: Liam.
  • Brawn Hilda: Fistina; this is the kind of character that makes you think Looma isn't that ugly after all.
  • Enemy Mine: With Ben in "Rules of Engagement".
  • Expy: Fistina's design is based on Crasher.
  • Good Costume Switch: When she's deputized as a Plumber in "Final Countdown", Fistina's armor switches to the Plumber color scheme.
  • Heel–Face Turn: In "Final Countdown", Fistina helps the Plumbers defeat Kundo, and is allowed to become a Plumber once she's served her time.
  • Husky Russkie: Fistina.
  • Joke Character/Ineffectual Sympathetic Villain: From what can be gathered, they're Psyphon's top enforcers. They are nonetheless rather ineffective.
  • Odd Name Out: For a chicken-like alien, Liam is a pretty normal-sounding name. Which may or may not be a Shout-Out to Richard.
  • Pet the Dog: Fistina gives up the Golden Fist because she can't bring herself to hurt Rook.
  • Powered Armor: Both Bubble Helmet and Fistina, though it's unclear whether Fistina is wearing one or just a cyborg herself.
  • Redemption Promotion: Once Fistina becomes a Plumber, she is far more effective as a heroic character than she was as a villain.
  • Rocket Punch: Fistina's main method of attack.
  • Punch-Clock Villain: Some of them. Fistina, in particular, seems to have nothing personal against Ben and Rook, even flirting with Rook occasionally (much to his dismay).
  • Shout-Out: Thunderpig is an obvious spoof of the Thunder Cats, while Fistina looks (and kinda sounds) like Crasher from Challenge Of The Go Bots.
  • Super-Empowering / Nice Job Fixing It, Villain: at the end of "Outbreak", Liam accidentally adds Kickin Hawk to Ben's repertoire by touching the Omnitrix.
  • Took a Level in Badass: In "Outbreak", the Omnitrix malfunctions and fuses them all with creatures. Fistina got fused with a Mechamorph, Bubble Helmet got fused with Shocksquatch, and Liam got fused with Humungousaur. Liam himself proved very efficient given his form, even punching Psyphon because he wasn't helping them in their initial escape.
  • Terrible Trio: Liam, Fistina and Bubble Helmet when working together. Not on the level of the Circus Freak Trio, but they come close.
  • The Usual Adversaries: In Omniverse, they are the most frequently seen villains.
  • Villainous Crush: Fistina towards Rook.
  • Weaksauce Weakness: Bubble Helmet's species can only breathe an atmosphere that's toxic on Earth; as a result, he needs his suit to be able to breathe on Earth.
    • Also, Liam has some weird addiction to birdseed, and feel an urge to eat it whenever he sees some, even in inappropriate situations.
  • You Killed My Father: Thunderpig once attacked Ben under the justification that Ben had supposedly eaten his father. Ben has no idea what he's talking about.

    Billy Billions 

Billiam "Billy" Billions

https://static.tvtropes.org/pmwiki/pub/images/billy_billions_ov.png

Billy is an old classmate of Ben's back when he was eleven. He's a genius kid from a rich family who developed a huge complex toward Ben, feeling like Ben was getting all the attention instead of him. Eventually, his jealousy led him to attempt to get rid of him by sucking him to Dimension 12. Due to attacking him in his Diamondhead form, however, he ended up zapping himself and trapped himself to the age of 11 as a result due to time working differently here. Growing smarter with age, he eventually found a way to come back on Earth to attempt revenge on Ben.


  • Adapted Out: Not him but his android bodyguard Mazuma doesn't appear in the reboot.
  • Attention Whore: He is really desperate for attention to the point where he'll send Ben to Dimension 12 for being more popular than him.
  • Big Bad Wannabe: He wants Ben to acknowledge him as his Arch-Enemy and destroyer. Ben barely acknowledged him as a villain.
  • Bodyguard Babes: He has one named Mazuma that is actually an android he built himself.
  • Butt-Monkey: He apparently was somehow even less popular than Ben at school (who in the Original Series was established to be pretty unpopular himself), his only attempt at getting rid of 10 years old Ben resulted in him being trapped in another dimension without Ben even realizing he was being attacked, the trip there left him stuck in the body of a little kid, and on top of this, when he finally does come back to get his revenge, not only does he learn his hated rival has become a world-famous superhero, but Ben doesn't remotely remember him.
  • Devilish Hair Horns: He's an evil teenager with a petty grudge against Ben, and his hair looks like a pair horns.
  • Disproportionate Retribution: Seriously, he tried to send Ben to another dimension ruled by Killer Robots because he was mad Ben got more attention than him.
  • Ditzy Genius: He's smart, yes. He's also a spoiled brat, incapable of thinking ahead or coming up with an idea of his own.
  • Evil Is Petty: Aside from the Disproportionate Retribution mentioned above, he expressed his intent to get revenge on everyone who supposedly wronged him. The next on his list after Ben? His school's lunch lady.
  • Gadgeteer Genius: While his maturity is debatable, his skills in robotics and machinery are definitely real.
  • Go Mad from the Isolation: At 11, he zapped himself to a universe where time does not progress and spent the next five years hiding from insane robots obsessed with killing organic life while remaining biologically 11. Lampshaded by Ben in his debut appearance.
  • The Greatest Story Never Told: He did save the world at the end of his debut appearance and got no credit for it. Still, considering he did it by mere luck and he was the one who brought the threat to begin with, his lack of credit is deserved.
  • Gonk: Even among Omniverse's simpler art style, his design stands out as disproportioned and notably uglier than most human characters.
  • Green-Eyed Monster: He hates Ben due to him taking all the popularity at school when they were kids (according to him at least).
  • Hair-Trigger Temper: He is very easy to irritate.
  • Insane Troll Logic: When he and all of The Vengers try to ambush Ben and are easily defeated by Brainstorm, who Ben himself says isn't even one of his heavy hitters, all Billy does is say the fight proves that Ben is a Sore Loser who knows The Vengers are better than him.
  • Insufferable Genius: He genuinely is brilliant when it comes to robotics and technology, but also happens to be a Spoiled Brat with the arrogance to match it.
  • In the Blood: In his own words:
    Billy: "I am a genius, by the way, born from geniuses; my parents basically invented modern robotics."
  • It's All About Me: Everything he does is about him.
  • Malicious Misnaming: Ben intentionally gets his name wrong in "The Vengers", claiming that he can't be bothered to remember it.
  • The Napoleon: Amazingly, he is even smaller than 11 years old Ben.
  • Never My Fault: He blames Ben for ending up zapped in Dimension 12, but he would never have ended up in this place hadn't he tried to zap Ben in the first place. Moreover, Ben didn't even do anything to zap him: he wasn't even aware Billy even existed.
  • Not Growing Up Sucks: He sure seems to think so.
  • Older Than He Looks: He is chronologically sixteen, but physically (and mentally) eleven.
  • Remember the New Guy?: Ben certainly doesn’t. Though he apparently knew Ben back when they were in elementary school.
  • The Resenter: It pretty much sums up the reason he hates Ben.
  • Smug Snake: He acts arrogant and insufferable, but he actually is one of Ben's least effective opponents.
  • Spoiled Brat: Even if he actually is sixteen, he still acts like one.
  • Too Clever by Half: Not as smart as he thinks he is, and overestimates himself.
  • Unknown Rival: To Ben, much to his annoyance.
  • Wealth's in a Name: Billy Billions is a rich kid.

Reboot Series

https://static.tvtropes.org/pmwiki/pub/images/billy_billions_2016.png

  • Adaptational Attractiveness: Maybe only because of the art style, but Omniverse Billy had an uglier, more crooked face, with a more pronounced horned hairstyle, and a significantly snider face. This one has smoother features and doesn't look any uglier than Ben or Gwen.
  • Adaptational Name Change: In the Classic Series, his full name is Billiam Billions, while in the Reboot, it's William Theodore Billions.
  • Adaptational Nice Guy: Make no mistake, he's still a brat, but Omniverse Billy had no redeeming quality whatsoever and was driven primarily by envy toward Ben. This one at least has Hidden Depths and a more sympathetic side.
  • Age Lift: He actually is a little kid in this show, rather than a teenager trapped in a kid's body like in the original franchise.
  • Anti-Villain: Of The Woobie variety, as deep down he's lonely and just wants real friends that don't just like him for his money.
  • Ascended Extra: A minor villain in Omniverse, he becomes part of the Rogues Gallery in the reboot.
  • Enemy Mine: He's forced to work together with Ben and Gwen in "Don't Laze Me, Bro" when his robots go rogue.
  • Evil Counterpart: He is more of one to Ben in this version due to them both being the same age and indulging in bratty, selfish or competitive behavior with each other often. Also, his first name starts with a "B" and his last name is numerical. This is especially pronounced in "Ben Again and Again".
  • Hidden Depths: He acts the way he does because he is convinced nobody would be interested in him if it wasn't for his obscene amount of wealth, and has no idea on how to make friends.
  • I Just Want to Have Friends: He confesses that he flaunts his money as a way to compensate for his lack of real friends, since he fears nobody would ever be friends with him unless it was to mooch off of his wealth.
  • Sour Outside, Sad Inside: "Billy Bajillions" explains that his brash personality comes from the fear that nobody would want to be his friend if he wasn't stinking rich.
  • Spoiled Brat: His entitled, bratty attitude is his defining characteristic.
  • Troubling Unchildlike Behavior: He will occasionally do things that could possibly kill people. In "Roundabout", he actively tries to murder Phil in order to gain more favor with the Forever Knight.
  • Yank the Dog's Chain: After he admitted his obnoxious persona is just a mask, Ben and Gwen actually decided to give him a chance to become friends... and then the Forgeti made everybody forget what happened that day.

    Fistrick 

Fistrick

https://static.tvtropes.org/pmwiki/pub/images/Fisttrick_1595.png
Voiced by: Eric Bauza

A human crook with a rather personable attitude.


  • Affably Evil: He's remarkably friendly for a crook, as he genuinely likes his gang instead of treating them like minions, and encourages healthy exercise and diets. He even casually greets Ben during Bros in Space.
    Fistrick: What the...? Ben 10? (chuckles) That you bro?
  • Badass Normal: He's human, yet he's able to hold his own against Shocksquatch, albeit with insulated boots. He still was remarkably easy to beat up for Kickin' Hawk, though.
    • He's also strong enough to knock down a Tetramand with his bare fists.
  • The Beastmaster: In "Bros In Space", he managed to turn Revonnah's Muriods into a formidable army, teaching them how to stand on two legs, operate machinery, and even taught them how to talk, though they could only say "Bro". Worth noting is that unlike Dr. Animo, he didn't use any machinery to do so.
  • BFG: One of the weapons he frequently uses.
  • Boisterous Bruiser: Loves to boast in battle.
  • The Brute: Acts as this to his employers, often someone to throw at an opponent to beat them up. Though he’s a bit smarter than most.
  • Character Catchphrase: "Bro".
  • Combat Pragmatist: In No Honor Among Bros he's shown using underhanded tactics in the Golden Fist Tournament, such as throwing salt in a Tetramand's face or using an electromagnetic pulse device to dismantle Fistina.
  • Delinquent Hair: Crazy hair without anything on.
  • Expy:
    • His design looks a lot like Marvel Comics villain Crossbones and his shirt looks like Punisher's due to having a white skull on it.
    • He also resembles DC Comics villain Bane, with both sharing Super-Strength and Fistrick's face paint resembling Bane's mask.
  • Genius Bruiser: Given that he reverse-engineers and mass-produces alien technology, his intelligence must be above average.
    • Assuming, of course, he didn't just steal it or paid for it. He did mention he got at least part of his tech from "a guy".
    • He also comes up with a pretty impressive plan in one of the later seasons.
  • Hoist by His Own Petard: How Ben managed to defeat him in his introductory episode, by using Gravattack to turn his missiles back at him.
  • Knows a Guy Who Knows a Guy: this exchange with Ben:
    Ben (as Shocksquatch): How did you get to Revonnah?
    Fisttrick: I know a guy.
    Ben (as Shocksquatch): How do you know about Amber Ogia?
    Fisttrick: I know a guy who knows a guy.
    Ben (as Shocksquatch): And the harvesters? Oh, wait wait wait. Let me guess, eh: you know a guy.
    Fisttrick: Knew a guy. Past tense.
  • Not-So-Harmless Villain: Despite being a muscle-bound thug in appearance and personality, Fistrick proved to be a competent adversary against Ben and Rook, and nearly blew up Rook's home planet had Ben not stopped him.
    • Villain Decay: His first two appearances presented him as a legitimately threatening villain, "Special Delivery" has him beaten ridiculously easy.

    Princess Looma 

Princess Looma Red Wind

https://static.tvtropes.org/pmwiki/pub/images/300px-Post-work_9373.png
Voiced by: Kimberly Brooks

A female Tetramand Princess who Kevin met during the time between the original series and Alien Force. In an attempt to get a piece of technology from the Tetramands, Kevin agreed to become Looma's fiancé so he could get said piece as a wedding gift. This came back to bite him back when she arrived three years later to get married to him. In order to avoid it, Kevin pulled out a Batman Gambit that led Ben to become Looma's fiancé instead of him.


  • Abhorrent Admirer: Because of her violent attitude, it's no wonder why Ben doesn't reciprocate her feelings at all.
  • Affably Evil: Not so much toward Kevin, but she acts genuinely nice and sweet when interacting with Ben after they got betrothed. When she lost her engagement to him at the end of "Rules of Engagement", she genuinely seemed sorry about him and affectionately told him goodbye.
  • All Amazons Want Hercules: She's an incredibly strong Warrior Princess pledged to any man who can defeat her in battle. Ben learned this the hard way.
  • Anti-Villain: She's genuinely committed to her fiancés and an honorable warrior who respects a Worthy Opponent, but her Royal Brat personality and her planet's dangerous customs still make her an antagonist.
  • Ax-Crazy: She'll threaten war against an entire planet if she doesn't get her way.
  • Best Her to Bed Her: Following her species' culture, this is how Kevin and later Ben end up fiancé to her. Note that this is no easy feat even for Tetramands because the females of the species are both bigger and stronger than males.
  • Blood Knight: One reason why she's interested in Four Arms because he's the only Tetramand who defeated her. She also shows a slight smile when she sees Julie in her Powered Armor, meaning she's eager to fight her.
  • Blue-and-Orange Morality: Due to her species' culture being oriented entirely around fighting, a lot of things that seem awful by human standards are normal wedding planning for her.
    • It's Tetramandian tradition for the bride to collect four "items" and present them to the groom's parents. The four items? Something conquered, something bruised, something severed, and something blue. Her picks are Esther (proving she conquered the Kraaho), Julie (who was bruised during the fighting), one of Fistina's hands (something severed), and Rook (something blue).
  • Brutish Character, Brutish Weapon: Befitting a strength-obsessed Blood Knight like her, her preferred weapon is a massive warhammer, only her being a technologically advanced alien mean It can also shoot lasers.
  • Characterization Marches On: In "Many Happy Returns" and "Rules of Engagement", she didn't seem to care if Ben was human and was talking lovingly to him after they ended up engaged, regardless of his form. Come her third appearance, she is now interested in his Four Arms form only for no clearly explained reason.
  • Cool Helmet: Fittingly for a Tetramand princess, she wears a war helmet instead of a crown.
  • Daddy's Girl: She and her father talk in the familiar sickly sweet way one would see a princess talk to her father. He's even willing to destroy Earth to get her back her fiance.
  • Dark Action Girl: A strong foe who could defeat many characters by her own.
  • Enemy Mine: She teams up with Ben and all the other girls against Charles Zenith in "The Most Dangerous Game Show".
  • Expy: She is essentially Maxima as a Tetramand.
  • Female Misogynist: Looma doesn't like fighting other girls. She actually seems to look down on them.
  • Graceful Loser: After being defeated by Ben, Fistina, Ester, and Julie, she acknowledged Julie as Ben's beloved, but threatens to crush her skull the next time she sees her (although she did say it with a wink and a smile).
  • Hypocrite: See Female Misogynist above.
  • Insane Equals Violent: She's an Ax-Crazy Warrior Princess who will take almost any excuse to fight.
  • The Juggernaut: Fights with her usually end with her opponents retreating. It usually takes more than just Ben to defeat her.
  • Large Runt: Looma appears to be much smaller than the rest of her species. Despite this, though, she can easily lift a father who dwarfs her, and still cannot find a Tetramand who can defeat her in combat.
  • More Deadly Than the Male: Her hopeless romanticism, coupled with her Daddy's Girl credentials, can make Looma come across as a bit unstable and ruthless to your average person, even by Tetramand standards. As noted above, female Tetramands are also the males' better in terms of physical prowess and thus considered to be more formidable warriors.
  • Multi-Armed and Dangerous: As a Tetramand, she possesses four arms, and she's a One-Woman Army who can easily defeat many opponents at once.
  • Obliviously Evil: In "Rules of Engagement", she gets into fights, causes property damage, and kidnaps people but from her perspective, it's standard Tetramand wedding preparations.
  • Pet the Dog: Helps to save Ben in "The Most Dangerous Game Show".
  • Pintsized Powerhouse: Not to humans (she is taller than any regular human being), but to her own species; she is the smallest Tetramand we have seen so far, and yet she is able to take down enemies like Armodrillo, crush her own, much taller father with a hug and is the strongest warrior in her family.
  • Psycho Ex-Girlfriend: More like Psycho-Ex Fiancee toward Kevin.
  • Plot Hole: In her debut, Looma said she wouldn't return until 3 Earth years. Come her next appearance, Looma quickly returns to Earth, despite Ben still being 16.
  • Royal Brat: Despite being a powerful warrior she acts like a child.
  • Sitcom Arch-Nemesis: Has this dynamic with Attea, even after they agree to stop fighting over Ben they just find something else to fight over.
  • Story-Breaker Power: Looma is definitely one of Ben's more formidable opponents, due to her species's nature along with her Yandere tendencies. It became apparent in her first two appearances that it took the forces of many, many characters to successfully neutralize her. Naturally, this is balanced out in "Catfight", where she fails numerous time to handle the conflict involving a mind-controlled Ben, constantly arguing with Attea and being overwhelmed by Rath.
  • Statuesque Stunner/Brawn Hilda: Zig-Zagged between the two; she is ridiculously strong even by Tetramand standards, and since she is fiancée both times to a character much smaller and technically weaker than her physically, she ends up dominating them. Plus, Kevin tries to escape her like the latter. Still, she is quite the looker for someone of her species.
  • Status Quo Is God: Technically, her engagement to Ben was cancelled at the end of Rules of Engagement after she lost to Julie, and she seemed willing to accept it. The very next time we see her, she has inexplicably forgotten about this and attempts to hunt down Ben once more.
  • Victory Is Boring: The reason why she can't find a husband—no other Tetramand can beat her in combat.
  • Warrior Princess: Nothing unusual in her species since female Tetramands are stronger than males.
  • Yandere: This is one woman you don't want to see scorned. She will (literally) hunt her lovers down to the ends of the Earth and threaten to destroy the entire planet if they try to escape her.

Nyancy Chan

Voiced by: Gwendoline Yeo

Nyancy Chan is a human female with the ability to hypnotize cats or cat-like creatures into doing her bidding.


  • The Beastmaster: Cats only.
  • Cat Girl: Well, she dresses as one, at least.
  • Enemy Mine: With the other female characters in "The Most Dangerous Game Show".
  • Flunky Boss: How dangerous is she depends on what kind of cats are under her control, she's pretty much harmless if no cats are around.
  • Harmless Villain: To the point Ben flat-out dismisses her in "Catfight", feeling she isn't worth his time. It backfires when he turns into Rath, though.
  • Laughably Evil: It's very hard to take seriously given her tendency for silly behavior like speaking or acting like a cat, while baby talking to her cat minions including Rath, when he ended up under her Mind Control.
  • Mind Control: Only works on cats though, and Rook can resist it, as he's a humanoid with some minor cat features. It does work on Rath though.
  • Pet the Dog: She helps to save Ben in "The Most Dangerous Game Show".
  • Semantic Superpower: Zig-zagged; on one hand, her power does work on every type of feline, including tigers, but not on aliens with feline features like Rook. On the other hand, it does work on Rath, a humanoid tiger-like alien.
  • This Looks Like a Job for Aquaman: A rare villainous example; so far, the only time she was ever able to be a real threat was because Ben was unlucky enough to turn into Rath in her presence.
  • Triangle Shades: Wears these.
  • What Kind of Lame Power Is Heart, Anyway?: Controlling feline species isn't exactly a big deal in a universe where the hero fights Galactic Conquerors on a regular basis.
  • Why Did It Have to Be Dogs?: Pretty obviously.

    Lord Transyl 

Lord Transyl

https://static.tvtropes.org/pmwiki/pub/images/lord_transyl_958.png
Voiced by: David Kaye

Lord Transyl is the former Lord of Anur Transyl, and a member of the extinct Vladat species. He was resurrected by Zs'Skayr. He has the ability to create creatures called Corrupturas, which enable him to control anyone they attach themselves too. He is also the genetic source for Ben's Whampire transformation.


  • And I Must Scream:
    • Anyone he controls is fully aware of what is going on, but unable to override his control. Even speaking seems to take a good deal of effort.
    • He himself suffers this fate, as Viktor puts him in a coffin floating in space and pushes said coffin in front of the sun.
  • Back from the Dead: Vladats normally turn to ash when they die, making it impossible for DNA to be collected, and thus making that kind of revival impossible. Zs'Skayr got around this by using Lord Transyl's hand, which was apparently severed before death, and the power he stole from the Alpha Rune.
  • Classical Movie Vampire: Envokes it by his looks.
  • Establishing Character Moment: The very first thing he does upon being resurrected is express his need to feed, then rush on Dr. Viktor and Kuphulu to devour their life force.
  • The Dragon: Becomes this to Zs'Skayr in the Galactic Monsters arc.
  • Evil Overlord: He once was this to Anur Transyl. His rule was apparently so horrific that even Dr. Viktor questions his master resurrecting him and ultimately betrays him to stop Transyl.
  • Informed Ability: He is mentioned to be capable of Vampiric Draining, but we never get to actually see him doing it. Whenever he is about to feed on someone, he is either stopped or forced to let his prey go. Possibly because the writers assume showing such a scene wouldn't be a wise move in a kid show.
  • Life Drain/Vampiric Draining: How his race feeds. It wouldn't work on Ectonurites, due to their lack of conventional life force, however.
  • Fantastic Racism: He views all other species as inferior to the Vladats. It doesn't keep him from allying with Zs'Skayr, though Zs'Skayr showed him who's boss.
  • Hypnotic Eyes: Can use them as an alternative to his Corrupturas. Whampire's immune due to Ben's Heroic Willpower.
  • Last of His Kind: And only because he came Back from the Dead.
  • Logical Weakness: If his Corrupturas can't stick to a person's head, he can't control them.
  • Mind Control: He can do this with his Corrupturas. Whampire and Hobble are immune to it due to Ben's Heroic Willpower and Hobble having mucous on his face that keeps them from sticking to his face.
  • Our Vampires Are Aliens: He also feeds off energy instead of blood.
  • Sealed Evil in a Can: While Zs'Skayr was killed (again), he's sentenced to this fate by Dr. Viktor.
  • Villain Team-Up: With Zs'Skayr.
  • Weakened by the Light: Though not as badly as Zs'Skayr.

    Benevelon 

Benevelon

https://static.tvtropes.org/pmwiki/pub/images/benevelon_stand_9.png
Voiced by:Micheal Goldstorm

An alien who attempts to bring "peace" to Earth..by destroying everything with his killer robot.


  • Evil Is Hammy: It's rare for him to be quiet
  • Ironic Name: His name is a play on "benevolent" which means to have good morals and a peaceful nature. Whatever Benevelon's doing is the opposite.
  • Killer Robot: He has one named B.L.R.R.T, who stands for Big, Large, Rampaging, Robot of Terror.
  • Noodle Incident: When he met Luhley, he called her a Galvan sent by his old nemesis, Azmuth. This means he has some tension with Azmuth at some point.
  • Rubber-Forehead Aliens: If it wasn't for the grey skin, pointy ears, and antennae, he could pass off as a human.
  • Villain: Exit, Stage Left: Does this in a flashback scene. He tries to do it again in the present, but is stopped by Four Arms.
  • We Come in Peace — Shoot to Kill: Claims he wants to bring "peace" yet uses a killer robot to destroy Area 51.

    Kundo 

Master Kundo

https://static.tvtropes.org/pmwiki/pub/images/kundo_6667.png
After becoming a Cyborg 
Voiced by: Jeff Bennett

A Revonnahgander fond of the old ways of his planet, and a master of Ravonnah Kai, their marital arts (whom he taught to Rook Blonko before he left.) A cantankerous elder, he particularly hating technology, outsiders, or those that have betrayed the old way of life.


  • Archenemy: He appears to have become this to Rook.
  • Badass Normal: Before becoming a cyborg, he was able to fight Ben equally merely through his world's martial arts (Revonnaganders are pretty similar to humans in terms of base assets like strength or speed, making it even more notable.)
  • Boomerang Bigot: After being turned into a cyborg, he still sees technology as evil. He even labels himself as a "walking contradiction".
  • Broken Pedestal: Rook did not want to harm his former teacher until learning he assaulted his father for letting Shar leave to become a Plumber. After that, the gloves are off.
  • Charles Atlas Superpower: The whole point of Ravonnah Kai. As far as we know, Revonnahganders aren't particularly stronger or faster than humans, yet Kundo's techniques allow him to do things such as create shockwaves by hitting the ground, breaking machines (including the Proto-tool) to pieces with his bare hands or fight on equal ground with several of Ben's aliens.
  • Crippling Overspecialization: He's a master of Ravonnah Kai. Just Ravonnah Kai. Rook's experience fighting all manner of aliens (While Kundo rarely fights anything but other Revonnahganders) does him in when they fight.
  • Curb-Stomp Battle: Dishes these out to Ben's aliens when the latter tries to fight him. The only transformation used that makes Kundo fight seriously is Kickin Hawk, and even that transformation is still quickly outmatched.
  • Enhanced Punch/Power Palms: The "Stone Cutter" technique works like this, where the user focuses their energy into creating a powerful punch or palm thrust.
  • Establishing Character Moment: He makes his bigotry toward technology and outsiders readily apparent, and then, when Rook Da refuses to get out of his way, unsympathetically and coldly defeats him.
  • Evil Luddite: A hypocritical one no less. He has a large disdain of technology and favors the old ways. The hypocrisy comes from the fact that the hate is arbitrary and this has been pointed out several times.
  • Evil Makes You Ugly: After being severely burned and losing his arm, he's gotten scars and a clawed cyborg arm, with his eyes having turned red.
  • Hoist by His Own Petard: After he becomes a cyborg, he tried to Invoke this trope by using the Plumbers' own technology to destroy all of the Plumber bases in the galaxy.
  • Hypocrite: His hatred of technology is, as Rook puts it, arbitrary, as technology is just as prominent on Revonnah than any other world. There's also his extreme dislike of outsiders, which is common among Revonnahganders, yet he makes a deal with one involving their amber ogia to leave the planet. Shar calls him out on that last one and going against the old way of life he says others are forsaking, yet he blames Rook for forcing him to make that call.
  • Knight of Cerebus: In both of his appearances, he is depicted as a competent, dangerous opponent. The only bit of comedy seen is in his first appearance in his intense shock and being overwhelmed by the various technological aspects of Earth. Even then, it's not much.
  • Knight Templar: Sees technology as as nothing but evil, and after becoming an insane cyborg, becomes determined to purge it from the universe. He even outright proclaims he will be a hero that future generations will tell stories of.
  • Never My Fault:
    • When Shar calls out Kundo's hypocrisy in making a deal with an outsider despite his hatred of them, he blames Rook for making him resort to it.
    • Kundo also blames Rook for dousing him in depleted blastonium, when he actually attacked Rook first with the "Stone Cutter", only to get send flying by the recoil at a tank full of blastonium when it was blocked by the Proto-Tool's shield. Rook even tried to save his teacher only for the substance to spill onto him.
  • Noble Demon: Downplayed example. Despite his cold behavior, he speaks in a polite and dignified manner. Furthermore, during his fight with Ben, he never actually attacks Ben when he's distracted or preoccupied, always giving Ben time to transform before continuing to fight and would only strike the killing blow if he gets knocked out.
    • Subverted by his second appearance.
  • Non-Standard Character Design: His ears are far pointier than Rook's, along with having "sharper" facial markings, unlike most other Revonnahganders. Besides making him look older, it makes him look meaner.
  • Obviously Evil: He has a far "sharper" design than any other Revonnahgander introduced in the series and has a very cold, uncaring attitude toward most anything around him.
  • Replacement Flat Character: In a sense. Rook Da came to accept his son and daughter's choices in lifestyle along with respecting Ben. Kundo pretty much now takes the role of the bigot with a hatred of outsiders, except far more villainous.
  • Sanity Slippage: Before he was simply a xenophobic bigot who wanted to protect Revonnahgander culture. After his operation, he's all that, plus a complete maniac bent on the destruction of the Plumbers. By the time he’s defeated a second time and taken to a mental institute, he’s practically ranting his beliefs like a madman.
  • Self-Serving Memory: He thinks Rook intentionally doused him in the blastonium that nearly killed him, even though he actually attacked Rook first and was send flying by the recoil into a tank holding the substance when it was blocked. When Rook points out that’s not what happened, Kundo insists that it is.
  • Signature Move: The "Stone Cutter." Word of God also states that the technique is too advanced for Rook to use.
  • Supernatural Martial Arts: A master of Ravonnah Kai, where he prefers using the "Stone Cutter" technique that's capable of creating powerful shockwaves by punching the ground and could smash through Rook's Proto-Tech armor with ease.
  • Technopath: After becoming a cyborg, he can connect himself to machines and control them.
  • Ungrateful Bastard: Still hates technology despite the fact that he'd be dead if he hadn't been turned into a cyborg.
  • You Are What You Hate: Is turned into a cyborg due to serious burns on his body. Unlike Will Harangue being turned into an alien hybrid, this is not Played for Laughs at all.

    Subdora 

Subdora

https://static.tvtropes.org/pmwiki/pub/images/subdora_1122.png
Voiced by: Tara Platt

Subdora is a Merlinisapien (Chamalien's species), a minion of Maltruant and the girlfriend/accomplice of Exo-Skull.


  • Classy Cat-Burglar: She tries to be, but Exo-Skull's method of brute force is usually more effective.
  • Cute Monster Girl: Her figure is more humanoid than Chamlien or Prisoner 775's.
  • Dick Dastardly Stops to Cheat: At one point, she successfully overpowers Ben, in his human form no less, after he tried to stop her from stealing Kai’s Orb. Instead of grabbing the item and making a break for it, she decides to stick around and try to kill him against a wall. Of course, she ends up wasting her time enough to allow Spanner to swoop in and scare her off. Although, this is later averted when she shows up later.
  • Enemy Mine: Joins forces with the side of good against Charles Zenith in "Most Dangerous Game Show".
  • Force and Finesse: Finesse to Exo-Skull's force.
  • Hollywood Chameleon: Justified since she is an alien.
  • Hypocritical Humor: Complains that Exo-Skull's burglary techniques are nothing more than a bunch of tired clichés... while attempting to be a Classy Cat-Burglar, itself a cliché.
  • Huge Guy, Tiny Girl: Tiny Girl to Exo-Skull's Huge Guy.
  • Interspecies Romance: She's a Merlinisapien, and Exo-Skull is a human-rhino hybrid.
  • Just a Stupid Accent: Speaks in a pseudo-Italian accent.
  • Pet the Dog: Helps to save Ben in "Most Dangerous Game Show".
  • Unholy Matrimony: With Exo-Skull.

A galactic personality and host of the galaxy-wide hit "The Most Delicious Game" where every woman a contestant knows compete for his hand in marriage. Three guesses as to who he shanghais to be his latest contestant. His species is a Pugnavore, a race of green humanoids who feed off of conflict. Certainly explains the title of his show better.


  • All Abusers Are Male: Him hosting "The Most Delicious Game" involves numerous females, but they're only a means of boosting his own career as a TV persenter.
  • Diabolus ex Nihilo: One of the more out-there alien antagonists to say the least. Which makes him an even more fitting Shout-Out to...
  • Emotion Eater: The main thing with his species, the Pugnavore. They feed off of drama, so Zenith creates constant conflict with his show to feed on. The fact there is an entire race of this has disturbing implications.
  • Great Gazoo: A goofy green alien with antennae and capable of doing plenty of strange things with just a snap of the fingers? It's surprising that it took several years for the Ben 10 franchise to make an homage to the character in the first place. It's unknown if all Pugnavores are like this though Attea's recognition of his kind and comments implied they are to a certain extent.
  • Ink-Suit Actor: He looks almost like Charles Phoenix, glasses and all, but with green skin and hair, and antennae on his head.
  • Jerkass: He kidnaps dozens of women, practically forces them to compete for Ben's hand in marriage, among them characters who are already in relationships, married or, most disturbing of all related to Ben (though Ben does get to eliminate the last one) Then keeps the losers to feed on off-season.
  • Reality Warper: To some extent. While flight, teleportation and some form of energy manipulation is what we've seen him do, it's not known if it's the full extent of his capabilities or if all Pugnavores can do it.
  • Rubber-Forehead Alien: Besides the green skin and antennae, Pugnavores look very much like humans, or at least Zenith does.
  • Weaksauce Weakness: Boredom. He needs to feed off conflict and drama after all.

A short, out-of-shape Tetramand criminal who made his first appearance in the Alien Force video game. He's a cameo character in "Special Delivery" and later as The Mole in "Mud is Thicker Than Water".


  • Acrofatic: Due to the nature of Tetramands, he's still quite fast despite his bulk.
  • Adaptational Wimp: In the Alien Force game, he's able to hold his own against Ben, even using a machine to regularly heal himself. In Omniverse, he runs off once the Plumbers found Psyphon's hideout & is easily defeated by Gwen.
  • Canon Immigrant: He initially was an original character in the video-game adaptation of Alien Force before actually having a role in the animation series.
  • Demoted to Extra: He barely appears much after his role in "Mud Is Thicker Than Water". His last appearance in Omniverse has him pass out via Skurd in "Stuck on You", but that's about it.
  • Fat Bastard: Unlike the rest of his species, Gorvan seems to be the only Tetramand that's overweight, and isn't a particularly nice person either.
  • Formerly Fit: Implied with some of his quotes during his fight in the Alien Force game, and he'll sometimes have to catch his breath after doing certain attacks.
  • Lightning Bruiser: Just like other Tetramands. His attacks do tons of damage, are quick, and he can even heal using a machine. This mainly applies to his appearance in the Alien Force game, however, and since he's a bit out of shape, he'll tire after doing certain attacks.
  • The Mole: He's the spy in "Mud is Thicker Than Water".
  • Non-Standard Character Design: Downplayed, but he's so far the only Tetramand in the series that's overweight, and is also far more shorter.
  • Stout Strength: His large frame and belly doesn't seem to affect how strong he is.
