Click here to see his present form 

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.


  • Anti-Villain: He started out as a very twisted Type II. However, once he got upgraded, he became a straight villain.
  • 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 Baritone: It comes with the voice acting of Corey Burton.
  • 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 Duumvirate: With Khyber and Dr. Psychobos.
  • 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 to collect the DNA require to complete the Nemetrix
  • Classic Villain: He represents Pride, Ambition, and Wrath.
  • Combat Pragmatist: He sometimes pretends to be unconscious to surprise opponents.
  • Composite Character: He can be considered a hybrid of Aggregor and Alpha.
  • 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 anihilate 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.
  • 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.
  • Expy: Let's see, a Hammy, technopathic villain that desires world domination. Why Technus old boy, is that you?
    • He's also similar to Megatron in voice and personality. In fact, each of his forms seem to channel a different Megatron. After his first upgrade he was G1 Megatron, after mutating into his dinosaur form he was Animated Megatron (ironically), and when he goes One-Winged Angel in "Showdown", he has gone completely Beast Wars with all the ham he generates.
      • As he possesses a single eye, arm cannon, and is voiced by Corey Burton, he's one for G1 Shockwave too.
    • And let's not forget Alpha, who also was a nanotechnologic-based villain with father issues and a tendencies to gradually change appearance.
    • He could also be considered one to Ultraman Belial. Shall we count down the ways? A corrupted member of his species with a Red and Black color scheme and a more hunched over stance. His master plan involves the destruction of his homeworld and his biggest flaw is his Pride. For bonus points, his gigantic One-Winged Angel form bears a passing resemblance to Arch Belial and fights against Way Big, who himself is a Shout-Out to Ultraman.
    • Yet another similarity that can be found is Brainiac, being The Chessmaster and being an evil alien with the ability to assimilate and control technology into his being. He shares a voice actor with him as well.
  • Eye Beams: Just like all Mechamorphs, he is able to project a large ray from his eye.
  • Famous Last Words: The last thing he says before being Taken for Granite: Curse you, Ben Tennyson!
  • 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.
  • 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, on the whole, were an unexpected but positive benefit of a life-giving experiment on their 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.
  • 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.
  • 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 the season 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.
    • 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: Destroyed Ben's Feedback transformation solely for the sake of hurting Ben by obliterating 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. The latter being particularly jarring as his powers were explicitly stated to be limited to technology.
  • Nigh Invulnerable: 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 visionary rather than evil.
  • Obviously Evil: Let's see: Red and black skin? Check. Tendencies to deliver long bombastic tirades about himself? Check. Traumathized 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 starts 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.
  • 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 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 utilizes a quieter computer-esque monotone voice which has 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.

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!"

An Cerebrocrustacean (Brainstorm's species) scientist who is responsible for the creation of Khyber's Nemetrix. Dr Psychobos has a strong despise of the Galvan specie 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 Galvan's are smarter than Cerebrocrustacean's. Blucik and Driba told him that the dumbest Galvan is still smarter than the most intelligent Cerebrocrustacean and he went totally ballistic.
  • Big Bad Duumvirate: With Malware
    • Now forms one with Princess Attea, but seems to have been Demoted to Dragon since Malware's defeat.
  • 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.
  • Catchphrase: "(random appellation) -and I use the term loosely."
  • The Cameo: It's a blink-and-you'll-miss moment, but he makes an appearance in "Special Delivery" during Psyphon's auction.
  • 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.
  • Evil Genius: To his frustration no matter what he does his evil genius will always be second to the Galvan race.
  • Fantastic Racism: He expresses this toward the Galvans, for whom he is trying to prove Cerebrocrustaceans are superior to. Then taken to horrible extreme 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 spam 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 galaxy, arguably four), and his whole motivation focus around proving that his own species is superior to Galvan.
  • Insufferable Genius: He's basically Albedo as a Cerebrocrustacean.
  • Knight of Cerebus: Downplayed. He's got much more humor-based quirks, but he appears to be able to overpower both of his coworkers, and actually was smart enough to take a piece of the Omnitrix from Ben.
    • And then he tries to assassinate Azmuth...
  • 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, contempting 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 most sane 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: Cobstantly 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.
  • 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: See Catchphrase.
    • He also 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?

     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. Which ever alien you pick, will be your last!"
  • Badass Normal: He has no superpowers, yet can go toe-to-toe with Rath
  • The Beastmaster: Has a dog whom he tamed to an extant.
  • Benevolent Boss/Bad 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.
  • Blue and Orange Morality: While he didn't bother feeding Zed when she was his pet, it wasn't out of egoism 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.
  • 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 portray him as this. He seems to have an equipment specifically built to face each one of them.
  • The Dog Bites Back/Dirty Coward: 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.
  • 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: To 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 Malware 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 sort of an alien version of Kraven the Hunter. 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.
  • 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.
  • Irony: It's implied that his own natural predator is already in the Omnitrix.
  • Knife Nut: He hasn't really used it so far, but he is often seen playing with one. In "It Was Them", it was strongly hinted he was about to behead Ben with it.
    • He finally uses it in "Malefactor" to fight Rook.
  • 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 still technically a Serial Killer.
  • The Stoic: Geberalky reacts to everything with a dull look.
  • 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 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: As of "The Ultimate Heist", he's working with Albedo now.
  • Weaksauce Weakness: He's afraid of Nemuinas (Pesky Dust's species). He's so afraid of them that he can't keep his mouth shut about that fear when Ben turns into one and proclaims it a "Lame alien".
  • 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.

  • Fangs Are Evil: Vicious fangs.
  • Me's a Crowd: As the natural predator of Ditto's species, it also has the ability to duplicate itself. And thanks to the Nemetrix, each copy can transform into a different predator.
  • One-Winged Angel: Thanks to Albedo's upgrades to the Nemetrix, it's capable of turning into an Ultimate Panuncian.
  • Red and Black and Evil All Over: Res and black and serves an evil master.
  • Shapeshifting: Does this with the Nemetrix.
  • What Happened To The Dog: It was never seen again after escaping with Khyber in "For a Few Brains More".

    Psyphon's Gang 
Bubble Helmet voiced by John DiMaggio
Fistina voiced by Morgan Lofting
Liam voiced by Paul Eiding

A Gang of alien criminals introduced in Omniverse as Psychon'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.

https://static.tvtropes.org/pmwiki/pub/images/Liam_Fistina_and_Bubble_Helmet_in_Chris_10_3589.png

  • 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 maybe or may not 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 weither 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 Humongousor. 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 breath an atmosphere that's toxic on Earth; as a result, he needs his suit to be able to breath on Earth.
    • Also, Liam has some weird addiction to bird seed, and feel a 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 
https://static.tvtropes.org/pmwiki/pub/images/Aziz-4_3_r560_7265.jpg

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.

  • 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 has been 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.
  • 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 than 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.
  • Expy: A rich Bratty Half-Pint the likes of Reggie Van Dough. Child genius riding around on a jetpack like Gizmo.
    • He's also one to Syndrome who is also a genius inventor from the hero's past who declares himself their arch-nemesis. Plus, his robots resemble the Omnidroid with their clawed hands and rotating heads with slits for eyes.
    • Furthermore, though this was probably unintentional, the concept of a kid from a rich family who has a jealousy toward another kid with a Chronic Hero Syndrome does have similarities with Shinji Matou.
  • Gadgeteer Genius: While his maturity is debatable, his skills in robotic 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.
  • 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.
  • Horned Hairdo
  • Insufferable Genius: He genuinely is brillant when it comes to robotics and technology, but also happens to be a Spoiled Brat with the arrogance matching 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.
  • 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 cronologically sixteen, but physically (and mentally) eleven.
  • 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.
  • The Napoleon: Amazingly, he is even smaller than 11 years old Ben.
  • The Resenter: It pretty much sums up the reason he hates Ben.
  • Too Clever by Half: Not as smart as he thinks he is, and overestimates himself.
  • Unknown Rival: To Ben, much to his annoyance.

Reboot Series

https://static.tvtropes.org/pmwiki/pub/images/nubilly.jpg
  • Adaptational Attractiveness: Maybe only because of the artstyle, but Omniverse Billy had an uglier, more crooked face, with a more pronounced Horned Hairdo, and a significantly snidier face. This one has smoother features and doesn't look any uglier than Ben or Gwen.
  • 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 Hiddephts 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.
  • Enemy Mine: He's forced to work together with Ben and Gwen in "Don't Laze Me, Bro" when his robots go rogue.
  • 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.
  • 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.
  • 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

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

  • Badass Normal: He's human, yet he's able to hold his own against Shocksquatch (albeit with rubber 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.
  • Catchphrase: "Bro".
  • Con Man: His job.
  • 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 electro-magnetic pulse device to dismantle Fistina.
  • Delinquent Hair: Crazy hair without anything on.
  • Expy: His design looks a lot like Marvel Comics villain Crossbones.
  • 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: How did you get on Revonnah?
    Fisttrick: I know a guy.
    Ben: And how did you know about the fruits?
    Fisttrick: I know a guy who knows a guy.
    Ben: And how did you learn the Muroids how to operate technology? Oh, let me guess: you know a guy.
    Fisttrick: Knew a guy.
  • 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.
    • Diminishing Villain Threat: His first two appearances presented him as a legitimately threatening villain, Special Delivery has him beaten ridiculously easy.
  • Tattooed Crook: Lots of tattoes.

    Princess Looma 

Princess Looma Redwind

Voiced by Kimberly Brooks

https://static.tvtropes.org/pmwiki/pub/images/300px-Post-work_9373.png
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 fiancée 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 fiancée instead of him.

  • Abhorrent Admirer: She is this towards Ben.
  • Affably Evil: Not so much toward Kevin, but she acts genuinely nice and sweet when interacting with Ben after they got bethroded. When losing her engagement to him at the end of "Rules of Engagement", she genuinely seems sorry about him and affectuously tells him goodbye.
  • Anti-Villain: A solid Type I.
  • Ax-Crazy: Though not to the extent of Malware.
  • Best Her to Bed Her: Following her species' culture, this is how Kevin and later Ben end up fiancée to her. Note that this is no easy feat even for Tetramands because the females of the species are both bigger and sronger than males.
  • 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).
  • Boobs of Steel: She has very buxom breasts in addition to being very strong.
  • 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 Fourarms form only for no clearly explained reason.
  • Cool Helmet: Awesome helmet.
  • 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.
  • Drop the Hammer: It can even shoot lasers!
  • Enemy Mine: With all the other girls in "The Most Dangerous Game Show".
  • Everything's Better with Princesses: VERY much subverted.
  • Expy: She is essentially Maxima as a Tetramand.
  • Female Misogynist: Looma doesn't like fighting other females. 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: Admittedly she only seems that way by earth standards.
  • 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: Emphasis on the dangerous part.
  • 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.
  • Proud Warrior Race Girl
  • Psycho Ex-Girlfriend: More like Psycho-Ex Fiancee toward Kevin.
  • 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.
  • Statuesque Stunner/Brawn Hilda: Zig-zag between those two tropes; 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 forgot about this and is chasing Ben again.
  • 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's a Graceful Loser mentioned above.

     Nyancy Chan 
https://static.tvtropes.org/pmwiki/pub/images/nova_imagem_da_pr-definio_de_nyancy_chan_2488.png
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

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 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.
  • Big Bad Duumvirate: With Zs'Skayr in the Galactic Monsters arc.
  • Classical Movie Vampire: Envokes it by his looks.
  • Egopolis: As an Evil Overlord, is is very likely that he's the namesake of the planet Anur Transyl.
  • 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.
  • 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, being a Vladat genetically and all.
  • 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 Whampire being a Vladat genetically 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.

    The Rooters 

The Rooters

https://static.tvtropes.org/pmwiki/pub/images/ben_10_omniverse__new_episode____meet_the_rooters_by_shuelahmed-d7p7xru_4973.jpg
A Black Op branch of the Plumbers who went rogue.

Tropes applying to the group as a whole:

  • Arc Villain: Of the sixth story arc in Omniverse.
  • Dark Is Evil/Evil Wears Black: Their uniforms are a black Palette Swap of Rook's armor. They tested the design in the Null Void before it made its way to the Plumbers.
  • Evil Counterpart: To the Plumbers.
  • Half-Human 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
  • 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 involve 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.
  • Ironic Hell: They are punished for their actions by having their status as Plumbers revoked and being left in the Null Void... 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.
  • The Last of These Is Not Like the Others: Phil got his mutation from the Nemetrix, he's the only one who's alien half is a non-sapient species, and he can change between his human and alien forms at will.
  • 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 the 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.
  • Renegade Splinter Faction: They are an offshoot of the Plumbers, founded by a former Plumber scientist, Proctor Servantis. They eventually loose their Plumber support and HQ.
  • Token Human: Phil, when he's not in his Terroranchula hybrid form.
  • 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: Zigzagged. 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.
  • Would Hurt a Child: The Rooters considered killing Ben a necessity for creating a safe and better universe.

Proctor Servantis

Voiced by Charlie Adler

  • 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.
  • 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.
  • Expy: He is also rather similar in appearance to the Transformers Animated Decepticon Mindwipe, who had the power of hypnosis.
  • 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.
  • 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).
  • 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.

    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 Albedo, 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.

Eon

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."
  • Dark Is Evil: Notable for being the only black-haired Ben.
  • Deadpan Snarker: He is the closest to the regular Ben, resulting in him having some of the same wit.
  • 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. Thought 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

  • Emo Teen: Appears to be one, given he doesn't care much for what's going on around him, and not even being erased from reality seems to get him upset.
  • In the Hood: Constantly seen wearing a hood.

Mad Ben

https://static.tvtropes.org/pmwiki/pub/images/mad_ben_7180.png
An alterante version of Ben who used the Omnitrix to enslave and seize power rather than become a hero. He is a tyrant and war lord in his dimension.

  • Anime Hair
  • Arc Villain: Of the seventh arc.
  • 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.
  • 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.

    Kundo 

Master Kundo

https://static.tvtropes.org/pmwiki/pub/images/kundo_6667.png
spoiler 
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 becoing 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 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.
  • 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 has 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 apperance in his intense shock and being overwhelmed by the various technological aspects of Earth. Even then, its not much.
  • 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 down, always giving Ben time to transform before continuing to fight.
    • 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 who wanted to protect Revonnahgander culture. After his operation, he's all that, plus a complete maniac bent on the destruction of the Plumbers.
  • 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 
Voiced by Tara Platt

https://static.tvtropes.org/pmwiki/pub/images/subdora_1122.png

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

    Maltruant 
Voiced by Mark Hamill

https://static.tvtropes.org/pmwiki/pub/images/maltruant_1664.png

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).

  • 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.
  • Arc Villain: of the Time War story arc.
  • 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.
  • 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 Back Stabbing 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.
  • Evil Counterpart: To Clockwork.
  • Evil Mentor: To Mad Ben.
  • Fate Worse than Death: He is stuck in a time-loop doomed to failure, and he's completely unaware of it.
  • Final Boss: He is the last major antagonist in Omniverse and the Ben 10 franchise.
  • A God Am I: His goal was to recreate the universe in his image.
  • 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 smashes 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.
  • 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 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 Appearance Is in the Eye of the Beholder beings that appear as Your Favorite person he just sees himself.
  • Nigh Invulnerable: If blown to bits, he'll just eventually rebuild himself. Even Ben blasting him with the equal of 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 golden Clockwork, he's mostly grey and black with a red glow.
  • 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 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 contins no time, it becomes a non-lethal Kryptonite Factor.
  • Villain Team-Up: He briefly formed one with fellow time-based villain Eon.

     Charles Zenith 
Voiced by: Charles Phoenix

An 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, who feed off of conflict. Certainly explains the title of his show better.

  • 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 distrbing implications.
  • Giant Space Flea from Nowhere: One of the more out-there alien antagonists to say the least.
  • Great Gazoo: A goofy green alien with antannae and capable of doing plenty of strange things with a snap of the fingers? It's more of a surprise how long before the Ben 10 franchise had their homage to the fellow. It's unknown if all Pugnavores are like this, though it is implied they kinda are.
  • Ink-Suit Actor
  • 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.

     Gorvan 
Voiced by: Rob Paulsen

https://static.tvtropes.org/pmwiki/pub/images/gorvan2.png

An out-of-shape Tetramand criminal who made his first appearance in the video games. 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.
  • Canon Immigrant: He initially was introduced in the video games before actually having a role in the animation series.
  • 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.
  • The Mole: He's the spy in Mud is Thicker Than Water.
  • Stout Strength: His large frame and belly doesn't seem to affect how strong he is.
