List of villains in Ben 10
This is a list of villains in the American animated television series Ben 10
Main Villains
Vilgax
Vilgax serves as the main antagonist of the series. Vilgax is a Chimera Sui Generis from a place called the Shadowy Realm, as stated by the bio that comes with his action figure (later releases of the figure state his homeworld as the "Null Void Frontier"). His appearance is very similar to Cthulhu. A vicious, intergalactic conqueror, Vilgax will stop at nothing to obtain the Omnitrix and use it to build an army capable of conquering every planet in the galaxy.
After being severely injured by the final attack from the ship transporting the Omnitrix, he was confined to a regeneration tank, ordering his robotic minions and cosmic bounty hunters to track down the Omnitrix, not realizing that it was a "mere child" who outsmarted and outfought his minions.[1] However, while his body was being repaired, he was also being cybernetically enhanced. When he was finally able to leave the regeneration tank, he had been enhanced to the point that none of the Omnitrix's aliens could so much as scratch him. Vilgax's ship was destroyed with him still aboard, but he survived its destruction and remained trapped within an iceberg floating in space until he was found by Kevin 11 in the episode "Back With a Vengeance". In that episode, he teamed up with Kevin in order to remove the Omnitrix, since Kevin shared its DNA. He is currently locked away in the Null Void dimension along with Kevin.
In Secrets, Max tells Ben and Gwen how he had a run in with Vilgax. Vilgax was stealing warheads from a military base when Max and his partner showed up. In the resulting fight, Vilgax was strapped to a warhead by Max and launched into his own ship.
According to events revealed in "Ben 10,000", Vilgax eventually escaped the Null Void but is torn to pieces during his last battle with Ben. Future Ben is not exaggerating about this fact, as Vilgax is fairly torn up when found by Future Dr. Animo. Animo revives Vilgax using his Transmodulator and the two of them then attempt to get revenge, only to be defeated by both the present and future Bens and Gwens. Future Ben ultimately defeats Vilgax by freezing him in a river.
Kevin 11
By all outward appearances a rebellious eleven year-old, Kevin is actually a sociopath that Ben meets after having an argument with Max. Kevin serves as season two's main antagonist along with Vilgax. Kevin has the unique ability to absorb any type of energy and release it at will. The energy can be used to activate or overload various machines and can also be used to make energy blasts. When absorbing energy from the Omnitrix's aliens, he becomes an incomplete, but effective, version of that alien. In his first appearance in "Kevin 11", he absorbed the abilities of Heatblast and Fourarms, using the former form's powers to get revenge on those who had wronged him. He absorbed the latter form's powers during his second battle with Ben to even the odds. After trying to take the Omnitrix from Ben, the Omnitrix emitted a feedback pulse to prevent Kevin from taking it, seemingly neutralizing his power. Kevin, however, exhibits the ability to create flame at the end of the episode.
As an unexpected side-effect of the feedback pulse, Kevin absorbed enough of the Omnitrix's power to permanently gain its powers, allowing him to perfectly copy the original ten alien forms (minus the Omnitrix symbol). Unfortunately, his human form is supplanted by the alien forms, forcing him to remain as an alien most of the time. He used some of those forms to cause a crime spree in San Francisco - and other cities - in "Framed". Eventually, the constant transformations caused him to mutate into a combination of the ten original forms, and he was permanently stuck in that form. All that remained of his former self were his pants, hair, and ears. Shortly after mutating and fighting Ben in this form, he was shot into the waters below the Golden Gate Bridge by a laser fired on the orders of Lt. Steel.
After formally returning, Kevin gloats that he has all of Ben's powers plus his own, making him "Kevin 11" (the name Kevin is credited under in the ending sequence of the show). Despite Kevin's claim, Ben notes that Kevin's powers aren't as good as his pure version (he quips that they're only one-tenth as strong, though this is likely not an accurate assessment[2]). Also, he lacks the majority of the special abilities of the Omnitrix's aliens such as Stinkfly's 360-degree field of vision or Ghostfreak's mobile eye; Vilgax's description of Kevin (a "misshapen, chaotic amalgam of creatures from the Omnitrix")[3] adequately describes his limitations. Being a random fusion of aliens, Kevin only has access to the powers most prevalent in his form, those being Fourarms' strength and additional arms, Heatblast's fire control (left arm), Diamondhead's projectile attacks (right arm), Stinkfly's flight and goo-spitting abilities, Wildmutt's sense of smell and arms, Ripjaws' razor-sharp teeth (and expandable jaw as seen in "Grude Match") and gills, and XLR8's speed. The rest of the aliens do not show up to any significant degree in his mutated form, so he evidently cannot access their powers. In addition to these limitations, Kevin seems unable to use the powers of any aliens Ben has gained since their original encounter. Kevin has also never used his energy-draining powers since his debut episode; this may be a drawback of his mutated form.
During his third appearance in "Grudge Match", Kevin attacks Ben to get revenge, blaming his condition on Ben. As the two battle, they are abducted and forced to fight in gladiator games. During their battles, Ben helps Kevin to realize the advantages of his mutated form. Because Kevin is an amalgam of aliens, he can mix and match their powers to make up for their reduced potency. Although forced to work together, Kevin's only goal was killing Ben. He is transported to a different galaxy at the end of the episode while locked in combat with Technorg.
Kevin returned in the episode "Back With a Vengeance", where he teamed up with Vilgax to defeat Ben, but he betrayed Vilgax later in an attempt to leave both in the Null Void, only for Ben to escape and leave him and Vilgax trapped. While it was confirmed in "Ben 10,000" that Vilgax eventually escaped, it is unknown as to what became of Kevin.
Ghostfreak
Ghostfreak is one of Ben's forms, freed from the Omnitrix. A copy of his personality was trapped within the Omnitrix when his DNA was sampled. He finally manages to force his way out of the Omnitrix in "Ghostfreaked Out." After peeling off the protective layer of skin that normally covers him, he tries to take over Ben's body in order to become whole again. On top of that, he plans to plunge the world into eternal darkness, thus being at full power all the time. After a failed attempt to possess Ben, he coerces Acid Breath, Thumbskull, and Frightwig to help him by taking over Thumbskull and tossing him about the room in a show of force. He appeared to have been killed when exposed to sunlight by Ben at the end, at which point the evil creature bursts into flames and is reduced to ash. Following this, Ben has not transformed into Ghostfreak and he has been replaced in the opening credits by Cannonbolt.
Ghostfreak returns in the episode "The Return", where he is revived by an alien scientist named Dr. Vicktor, who unofficially leads a group of horror-themed aliens loyal to him. The episode continues into "Be Afraid of the Dark", in which Ghostfreak attempts to plunge Earth into eternal darkness, with Doctor Vicktor and his cohorts working by his side. Ghostfreak also still desires to obtain the Omnitrix by merging with Ben, whom he pursues all the way into space. In the end, Ghostfreak is killed on board a space shuttle, when Max opens the shuttle's roof and exposes him directly to the sun. However, it is hinted that Ghostfreak could still return, for the DNA of his true form is revealed to have been restored onto the Omnitrix during the fight.
Secondary Villains
Acid Breath
Acid Breath is one of Zombozo's three minions. His appearance is quite like that of a zombie. He has the ability to project corrosive acid from his mouth in the form of either a vapor (hence the name "Acid Breath") or a liquid, a trick he implies was taught to him by his mother. This acid can easily dissolve whatever he wants it to, even metal. If his mouth is jammed by an object (such as a baseball), or if something causes him to cough and gag (such as when Gwen blew a fire extinguisher's contents into his mouth, calling him Stink Breath in the process), Acid Breath will be briefly unable to use his powers and will be vulnerable to attack. Acid Breath first appears in the episode "Last Laugh" and again in "Ghostfreaked Out". Dee Bradley Baker voices Acid Breath.
Bermuda Triangle Aliens
Within the Bermuda Triangle are a vast number of squid-like robotic creatures. They bring down ships and planes for an unknown reason, although a reference to them keeping all the craft in an underwater "parking garage" implies that they collect the craft, and have been doing so for quite some time judging by the age of some of the vehicles present. After Donovan Grand Smith took their energy orb, these aliens attempted to retrieve it. Many of them were wiped out when Edwin rigged the energy orb to implode, along with the hotel and everything in it. Whether or not there are any of the aliens left is unknown. These aliens appeared in the episode "They Lurk Below".
Charmcaster
Charmcaster is Hex's niece. Like Hex, she uses magic, but instead of using a staff, she has a bag from which she can draw all manner of items, such as magical explosives or throwing blades. Although small, the bag seems to have something of a pocket dimension inside (akin to hammerspace), allowing Charmcaster to store things within it that logicially should not fit (at one point, she produces Hex's magic staff, a item that is at least four feet tall). She is also skilled in various magical spells, although it's clear that she isn't as powerful as Hex.
In her debut appearance, "Tough Luck", she busts her uncle out of prison and assists him in trying to steal the Keystone. She manages to trick Gwen by putting on an act about hating her uncle, only to swipe the Keystone while hugging Gwen. She then gives Hex the Keystone. In the end it's revealed that Hex needed the Keystone to recreate the Charms of Bezel, and that she was manipulating her uncle into doing it so that she can take their power for herself. In the end, her powers, like Hex's, appear to have vanished.
Charmcaster returns in "A Change of Face", having somehow regained her powers. She attempts a body swap spell with Ben, hoping to take advantage of the Omnitrix to boost her magic. Her efforts fail, however, as her three attempts end in swapping with Gwen, being returned to her normal body while Ben and Gwen are swapped, and returning Ben and Gwen to their normal bodies. She is arrested at the end of the episode, and her bag is tossed into the sea. She is last seen in a juvenile detention ward, where she is about to be beaten up by two female inmates, both of whom Gwen spurned while she was in Charmcaster's body. Gwen procures her spellbook during this period, and keeps the item as a souvenir after Charmcaster is arrested. Kari Wahlgren voices Charmcaster.
Clancy
Clancy is a man who has the ability to control any type of insect; the source of this ability is never explained, though he may be a super-powered mutant. Clancy always speaks using first-person plural pronouns like "we," as he speaks for all of his insects as well. He once lived at 8610 Chester Street, which was an abandoned apartment building. When Councilwoman Liang tried to redevelop the area and have his home torn down, he kidnapped her with the intention of feeding her to his insects. Luckily, Fourarms was there to stop him.
After that plan failed, Clancy went to the nuclear power plant to cause a meltdown, which would kill everyone and everything in the city, except for the cockroaches, which are immune to radiation. Clancy made himself a protective suit out of cockroaches in order to survive the blast. A sick Heatblast, whose powers had reversed and gave him the ability to control cold instead of heat, stopped this plan. Finally, he attempted to take revenge on the trio. Once again, he is stopped, this time by Max's San Ju Yen Pien cold medicine, which attracted the bugs and overrode Clancy's control over them, at which point Max easily knocked him out.
Clancy doesn't appear to actually be deranged at first, just trying to save his home (although his comment about having his bugs eat the mayor seems a bit overboard), but starts doing things that show him to be sociopathic once it's destroyed along with many of his bugs. Clancy appears in the episode "Side Effects". Nicholas Guest voices Clancy.
Doctor Animo
Doctor Animo, voiced by Dwight Schultz, was once a promising researcher in veterinary science. His career was cut short when it was discovered that he was performing twisted genetic experiments on animals. He had hoped that his research would win him the Verties Award, which is an award in veterinary science. Because of the nature of his research, he lost the award to another doctor, named Kelly. This drove him mad, and he dropped off the map for five years until he could perfect his research. In the episode "Washington B.C.", he finally finishes his work.
By using the Transmodulator, a device of his own design, he could mutate animals into giant versions of themselves. The second phase of his work involved reanimating dormant cells, literally bringing dead animals back to life, namly a wooly mammoth and a T-rex. All of this was in pursuit of the award which he had lost. His quest ended in failure, since Ben was there to stop him, reversing the effects of his Transmodulator by damaging it. He was arrested in that episode.
He appears again in the episode "Dr. Animo and the Mutant Ray", where he creates a much larger version of the Transmodulator using the broken-off faceplate of the Omnitrix. This version mutates living creatures with alien DNA, creating odd mixtures of alien and terrestrial creatures, such as Heatbat. Before he can complete his plans to use a satellite to shoot the ray all over the world, Ben stops him with Gwen's help. Since his mutants were never shown being cured, it is possible that they are still around. For some reason, his trademark giant frog is also present, though he may have simply re-mutated it sometime after his original defeat. How and when he escaped is unknown. Oddly enough, his skin is yellow-green. A picture of him on Gwen's computer showed that he had normal skin in the past, making it likely that he experimented on himself, resulting in a mutation.
In "Ben 10,000", Animo is still alive, though his head is the only part of him that remains. However, it controls a unique apparatus that allows him to attach himself onto animals specially reformatted with a device (in this case, a white gorilla) and control them. He was the one responsible for creating Exo-Skull and reviving Vilgax. He was defeated by both Gwen and her future self, Gwendolyn, as well as a cybernetically-enhanced Grandpa Max.
The animals he has mutated or reanimated include a mammoth, a Tyrannosaurus Rex, a bat, a cockatoo, a hamster, a rhino and his trademark frog. Vilgax could be counted in as one of the creatures since Animo reanimated him. The same goes for Grandpa Max in "Dr. Animo and the Mutant Ray", when Animo turned him into a slug-like creature.
Doctor Vicktor
An alien resembling Frankenstein's monster, Doctor Vicktor works at NASA, disguised as a human scientist as a means to hijack a space shuttle. He is incredibly intelligent, and working for Ghostfreak; his immediate plan was to resurrect his master, whose ultimate plan was to prevent the sun's light from reaching the earth using various satellites (therefore meaning that Ghostfreak would be at full power all of the time). He serves as the unofficial leader of the three horror-themed aliens. The purple lightning that the previous two horror aliens appeared in was generated by a teleportation machine that he invented. His name is clearly based on Victor Frankenstein from Mary Shelley's novel.
His first appearance is in "The Return", where he succeeds in reviving Ghostfreak. In the next episode "Be Afraid of the Dark", Ben had to fight Vicktor and Ghostfreak on Earth. Ben accidently tranformed into Grey Matter and had to hide from Ghostfreak and Doctor Vicktor. When the Omnitrix timed out, Doctor Vicktor finds Ben and grabs him by the arm and he unintentionally adds his DNA to the Omnitrix. When Ben had to deal with Ghostfreak, Doctor Victor and the mummy alien in space, Doctor Vicktor shots a beam from his cannon on his back and it opens a vortex that sucks him and the mummy alien in it. It is unknown of what became of the two. Doctor Vicktor is voiced by Michael Dorn. Ben's Omnitrix version of Dr. Victor is named Benvicktor.
Enoch and the Forever Knights
The Forever Knights (seeming to be a reference or evil parody of the Knights Templar), known among outsiders as the Organization, is a secret society dedicated to collecting alien technology for their own benefit. Any aliens they catch along with that technology are dissected and studied, and any humans caught with them (like Howell) are immediately deemed worthless and are disposed of. Their entire organization dresses as if they were knights, complete with the appropriate, albeit heavily enhanced, weaponry and stylized facemasks. They use a coat of arms over a pair of crossbones as their symbols. Their leader is Enoch.
The Forever Knights appear in the episode "A Small Problem", then known only as the Organization. They attempted to dissect Grey Matter, but were thwarted. Their mansion was also destroyed, along with a fair portion of the advanced technology stored within. At the end of "A Small Problem", Enoch orders his subordinates to find out about Ben, Gwen, and Max.
They appear again in "Ultimate Weapon", in which their formal name is used. In "Ultimate Weapon", Enoch attempts to retrieve the Sword of Ekchuah (a sword of incredible power), only for it to crumble to dust when he finally finds it in a temple (according to Max, "That's what happens when your 'ultimate weapon' is over 5,000 years old."). He remains in the temple as it collapses, trying to collect the dust of the weapon.
In "The Unnaturals", Enoch and his organization resurface as part of an effort to replace the President with a robotic duplicate using a team of robotic baseball players fittingly called the "Squires". His plot was foiled by the Tennysons, though they remain unaware that he was part of it.
Enoch is voiced by Richard Doyle and his henchmen are voiced by Nolan North, his head scientist is voiced by Larry Cedar, and one of his knights is voiced by Khary Payton.
Exo-Skull
A cybernetically-enhanced rhino with a laser cannon for a horn, Exo-Skull provides a convenient introduction for Ben's future self. In "Ben 10,000", he sees Ben as XLR8 and Gwen shortly after their arrival in the future and attempts to kill them; XLR8 attempts to fight back, only to have the Omnitrix time out in its usual inopportune fashion. Ben 10,000 quickly arrives, also in the form of XLR8, to dispatch the creature. It was revealed that he was enhanced by Dr. Animo following a scan; based on the dialogue, Ben 10,000 had encountered him before in a different form. He can fire a powerful beam and a net from his horn. He is also the only one of Animo's mutations that was capable of speech. He is voiced by Richard McGonagle.
Frightwig
Frightwig is one of Zombozo's three minions. She has pale skin, a tight-fitting body suit, and five orange tentacles for hair. The tentacles are extremely powerful, giving her strength equal to that of Thumbskull. She is commonly defeated by Ben wrapping these tentacles around her whole body. She's also extremely quick. Frightwig appears in the episode "Last Laugh" and again in "Ghostfreaked Out". Cree Summer voices Frightwig.
Fungal Brain/Mycelium
The Fungal Brain is the head of a fungus colony which took control of Camp Opinicon in the episode "Camp Fear". The scientific name for such a structure in real fungi is called a mycelium. Incidentally, the Fungal Brain prefers to be called by that term. It has many mushroom-like minions who go and attack various campers. Its plan was to take control of the entire planet by spreading its spores into the atmosphere. It was killed when Ben threw a can of antifungal powder into his mouth, poisoning it and killing all its minions in the process. The Fungal Brain is voiced by Fred Tatasciore.
The Great One
The Great One is a giant, tick-like alien that travels from world to world, sucking the energy from the planets it lands on to feed itself. This process poisons and eventually makes the worlds it visits implode. Its shell is nearly impenetrable and its feeding process brings the ground to life as an extra defense, making it very difficult to attack. On top of that, it is followed by a group of worshipers that want to make sure that it completes its task. The Great One is destroyed from the inside by Ben as Cannonbolt. The Great One is responsible for the complete destruction of Cannonbolt's home planet about a week before it tried to destroy Earth, a somewhat ironic accomplishment considering its death at the hands of a member of the same species (albeit a spliced version). The Great One and the worshipers all appear in the episode "The Big Tick".
The Great One bears a strong resemblance to the Tree of Might from the movie, Dragon Ball Z: The Tree of Might, albeit as an insect rather than a plant.
The Great One's Worshipers
The worshipers are three aliens that accompanied the Great One. The first is a tall alien, who has a laser/hologram projector on his head and six tentacle legs. The second is a medium-sized alien with four eyes and a large battle axe, which can also fires lasers when swung. The third is a short six-armed alien with a laser on his forehead. The latter of the three can communicate with the Great One through direct contact. All three ride on hovering platforms and protect the Great One while it performs its task. After its destruction, they show their flimsy loyalty by worshiping Cannonbolt, who had destroyed the Great One not minutes before. They decide to depart when Cannonbolt reverts to Ben, considering a mere human unworthy of their devotion. They appear in the episode "The Big Tick". The three alien worshipers are voiced by Fred Tatasciore, Dee Bradley Baker, and Paul Eiding.
Heatbat
Heatbat is a bat mutated with Heatblast's DNA by Doctor Animo using the stolen faceplate from the Omnitrix. In addition to already being able to fly, it can also breathe fire and generate extreme heat from its body. Like all of his mutations, it is loyal to Doctor Animo and follows his commands. As with the real Heatblast, if Heatbat is doused in any sort of flame-retardant substance it will extinguish its fire and greatly weaken it. It is defeated by a hybrid between Heatblast and Ripjaws, dubbed Heatjaws. Its fate remains unclear, but Ben and Gwen are not seen taking the effort to demutate the creature before repairing the Omnitirx.
Hex
Hex is a powerful magician. In "Lucky Girl", he used five magical charms called the Charms of Bezel to gain the powers of levitation, fire, reincarnation, luck, and lightning in addition to his normal spellcasting. He sought an ancient spellbook known as the Archamada Book of Spells. It dates back to the 16th century and contains powerful spells that, when wielded by someone holding the Charms of Bezel, give the wielder unimaginable powers. He is eventually defeated by Ben, Gwen, and Max.
Hex returns in "Tough Luck", where he's searching for the Keystone of Bezel. With it, he can recreate the other five charms and multiply their power ten times. He is accompanied by his niece, Charmcaster, who is a weaker apprentice of his that freed Hex from prison earlier in the episode. She eventually betrays him an attempt to get the stones. As Wildvine, Ben crushes the five charms and damages the Keystone, causing it to drain both Charmcaster's and Hex's powers. He hasn't been seen since. Khary Payton voices Hex.
Joey/Rojo
Joey is the leader of a heavily armed female biker gang. When she tries to rob an armored truck, she is thwarted by Ben as Fourarms. The remnants of one of Vilgax's defeated drones soon fuse with Joey and she becomes Rojo (Spanish for red), a powerful cyborg. The upgrade gives her the ability to fly, super-strength, and a pair of blasters attached to each shoulder. Vilgax is able to communicate with her through the parts and force her to track down the Omnitrix for him. Joey is turned back to normal when Upgrade shorts out the spare parts, after which Gwen knocks her unconscious for attempting a sneak attack on Upgrade.
Joey is wild and amoral, and not hesitant to attack innocent bystanders just because they annoy her. Neither her real name or her cyborg name is mentioned in the show. Joey appears in the episode "The Alliance". Jennifer Hale voices Joey.
Jonah Melville
Jonah Melville is a hunter of rare animals, more commonly known as a poacher. He takes the animals he captures and sells them to the highest bidder. He often uses the cover of an animal-rights activist in order to disguise his activities. Jonah Melville appears in the episode "The Krakken", where he tries to steal the Krakken's eggs. He is defeated by Ripjaws and arrested. His name is a combination of two names that are associated with large water creatures: Jonah, the Biblical figure that was swallowed by a large fish (which Melville nearly was by the Krakken), and Herman Melville, one-time sailor and later writer of Moby-Dick, a story of a sea captain's obsession with a huge white sperm whale. Robin Atkin Downes voices Jonah Melville.
Kane North
Kane North is the twin brother of Abel North (a.k.a Kangaroo Commando). Kane holds a grudge against Abel because he made Kangaroo Commando's gadgets and Abel took all the credit. When Kane tried to escape, Ben as Wildvine fought him until the Omnitrix timed out. When Kane was about to strike Ben, Abel sneaks behind him and knocks him out. Kane and his brother are likely based off of Cain and Abel from the Bible. He and Abel are both voiced by John Cygan.
Kenko the Shapeshifter
Kenko appeared as the villain of Sumo Slammer Smackdown in "Game Over". He is a shapeshifter and archenemy of Ishyama, the hero of the game. He overhears Ben talking about the Upgrade token; believing it could be used to allow him to take over the real world, he attempts to obtain it. While Ben searches for the token, he fights and defeats Ishyama, then assumes his form after Ben reaches the Upgrade token first. He tries to trick Ben into taking him to the real world, but Max's timely intervention in the game revealed his ruse. As Upgrade, Ben's control over the game allows him to depower Kenko, revealing him to actually be a small, weak, gnomish creature. Afterwards, Kenko was defeated when he knocked himself out by accidentally hitting himself in the head with a piece of his own armor. Clancy Brown voices Kenko.
Kraab
Kraab is one of three alien bounty hunters sent to take the Omnitrix from Ben. He has gold-colored armor (although it is clearly much stronger than any form of gold found on Earth), a sideways mouth, four scythe-like legs, and a large, powerful pincer on his left hand. Within the pincer is a power blaster, combined with a chemical sprayer. He can also use his legs to burrow under the ground and travel quickly from place to place. He is an experienced bounty hunter and is smart enough to know of a chemical spray that takes away Ghostfreak's power to become intangible. Kraab appears in the episode "Hunted". Billy West voices Kraab.
Limax
The Limax are shape-shifting slime aliens from an unknown world. The Limax thrive in conditions of fire and heat, hence why they chose to begin their invasion plans in a retirement community situated in the middle of a desert in the summer months. They come to Earth to collect elderly people and devour them. The Limax seem to have a hive mind, being able to coordinate throughout a large area without any direct contact, though they do speak to each other. The Limax can merge with each other to form one gigantic Limax. They melt when exposed to cold water. After their plan to kidnap Aunt Vera's retirement community failed, most of them escaped on their spaceship. A few, however, were left behind. These aliens appears in the episode "Permanent Retirement". Dee Bradley Baker voices the Limax.
Megawhatts
Megawhatts (a play on megawatt and "What?") are mischievous little creatures composed of electrical energy who have the physical form of anthropomorphized batteries. They are black and yellow with plus and minus symbols on their back, similar to a battery, and a lightning bolt on their chest. The top of their heads constantly emit electricity. They stand roughly a foot high, have pointy legs (though they usually fly), and have only three fingers on each hand. Their language consists of a series of high-pitched squeaking and chirping noises, though they are apparently capable of understanding English.
Megawhatts can control electricity and inhabit electrical devices, controlling them from the inside. Being made from electrical energy, they are weak against things that ground it (water being a chief example). They grow stronger by absorbing electricity and can multiply if split in half or given enough power. It should be noted that that when the first one divided, both it and its clone seemed to be surprised, as if they didn't know they were capable of doing it. It should also be noted that Megawhatts are surprisingly strong for their size, and just one was able to lift Grandpa Max, who is many times its size, into the air by his underwear. Another notable ability of theirs is that the noises they normally use to communicate can, at a certain pitch and volume, shatter glass.
Megawhatts exist to have "fun", which in their case is to cause trouble wherever they go. While they cause a lot of damage, Megawhatts are not openly hostile to humans, merely lacking any self-control or sense of the harm they may be causing. They only openly attack after Ben tries to attack them, and don't retaliate against anyone but him.
They are said to be either lightning come to life, static cling run amuck, or an alien (the first two were said by the town leader and the last by Gwen). The latter of the three would seem to be correct, given Ben 10,000's use of a Megawhatt as a form on the Omnitrix. However, as the Omnitrix can absorb and integrate DNA for use by the wearer, they could still have originated on Earth.
They appeared in the episode "Tourist Trap", originally trapped in the world's biggest rubber-band ball. Ben's use of the Omnitrix accidentally empowers them enough to escape their rubber prison. They are currently imprisoned within the world's largest lightbulb, which was originally the world's largest fishbowl adapted into a makeshift prison. The mayor of Sparksville has it converted into a lightbulb to replace the lost attraction.
Mummy alien
This mummy alien appeared in "Under Wraps". This alien mummy was sent by Doctor Vicktor to find a dangerous element called corrodium that crashed on Earth millions of years ago. Grandpa Max explains that the crystals are a potent but unstable power source, and the radiation emitted by the crystals causes almost instant mutation in humans and other Earth-borne creatures. Todd Maplewood, a boy Ben and Gwen met, said it arrived in purple lightning, which is the same way the Yenaldooshi arrived in "Benwolf". Max states there may be a connection between the Yenaldooshi and the mummy alien, which is proven in "The Return". During Ben's battle with the creature, its DNA is absorbed by the Omnitrix, giving Ben access to the form. The mummy alien is frozen solid by Upgrade and buried, along with its corrodium, under a thick bed of concrete. It was released by the Yenaldooshi in "The Return", and assists in Dr. Vicktor's plan. In the next episode "Be Afraid of the Dark", Max and Gwen get trapped in a space shuttle and had to fight the alien mummy. When Ben was dealing with Ghostfreak, Doctor Victor and the mummy alien, Doctor Vicktor shots a beam form his cannon on his back and it opens a vortex that sucks the mummy alien and him in it. It is unknown of what became of the two. Ben's version of this alien is named Benmummy.
Phil
During Max's time with the Plumbers, Phil (voiced by Robert Patrick) was his partner. Together, the two managed to prevent Vilgax from stealing nuclear missiles, resulting in the destruction of Vilgax's ship. After that point, the work dried up and the Plumbers were disbanded. Though Max retired, Phil continued the work, capturing aliens and charging various people for the captures. During an incident with a small alien, he met up with Max again, and tried to get him to reform the Plumbers. After Max refused, he ended up calling for help to deal with some more loose aliens. He discovers that Ben has the Omnitrix during this second fight, and pushes even harder to reform the Plumbers. Through his constant insistence and the familiar aliens they'd been fighting, Max discovers that Phil had been using the Null Void Projector — a weapon capable of opening a portal to an alternate dimension, which was used as an alien prison — to con people into paying him to remove the aliens. After Max discovers his secret, Phil tries to get rid of him, but is stopped by Ben as Grey Matter. In the end, Phil ends up trapped in the Null Void. When Gwen asks what would happen to him, Grandpa replies, "There are some things about this job we're better off not knowing".
Pinky and Missy
When Gwen was in prison in Charmcaster's body , Pinky was the overall leader and Missy was her lackey. When Gwen escapes, Pinky and Missy decide to continue their life of crime instead of reforming, so Gwen betrays them by making a pair of guarddogs hold them until the police capture them. At the end, the real Charmcaster goes to the same prison, leaving Pinky and Missy to attack her for 'abandoning' them. They appear in "A Change of Face"; Pinky is voiced by Kim Mai Guest and Missy is voiced by Jennifer Malenke.
S.A.M.
S.A.M. was a robot designed to help the local TV weatherman, Vance Vetteroy, with his broadcast. When his creator started tampering with S.A.M. in the hopes of being able to control weather, not just report it, S.A.M. was struck by lightning and developed a somewhat HAL-like personality. He then set about on his own, trying to use his weather controlling abilities to cause natural disasters. Ben was able to take S.A.M. offline with help from Grandpa Max and Gwen by using a sound frequency at the end opposite of the spectrum from the hum SAM gave off. His name stands for Sounding Autonic Meterograph. S.A.M. appears in "Monster Weather" and is voiced by Jim Ward.
Sixsix
Sixsix is one of three alien bounty hunters sent to take the Omnitrix from Ben. He has purple armor and strange, clamp-like feet. He also has a jet-pack. His armor is covered with pouches that hold various weapons and projectiles, such as twin blasters, laser discs, a buzz saw, laser blade and whip, sonic weapon, throwing pikes, grenades, bolas, rockets, and several tentacle-mounted lasers coming out of his back pack. He also has several very strange small claws and hands that extend from his shoulders that are usually used to throw the small pikes coming out of his jet pack, or bombs when he is using his blasters.
Unlike the other hunters, Sixsix only speaks in his own language. The hunters can still understand him, though. Sixsix appears in the episode "Hunted". Sixsix later appears in "The Galactic Enforcers", teaming up with Volcanus as part of his plan to combine Element X with bisynthium alloy (an unspecified form of iron ore) to create an explosive capable of wiping out an entire solar system.
Slix Vigma
Slix Vigma is the coordinator for intergalactic-viewed gladiator games run on a massive stadium ship known as the Megacruiser. Slix himself is a robot that acts as the control center for the entire ship. To recruit gladiators, Slix kidnaps them from their native worlds and uses shock collars to keep them obedient. He then pits them against each other or various robots in fights to the death. Slix was destroyed by Kevin. Slix Vigma appears in the episode "Grudge Match". Armin Shimerman voices Slix Vigma. Slix Vigma's name appears to be a parody of six sigma.
Squires
Posing as a Little League Baseball team, the Squires and their coach, referred to only as Coach Finn, are robots manufactured by the Forever Knights as part of a plot to capture the President and replace him with a robotic double under their control. They knew that he would attend the finals for the Little League baseball season and would have the team win at any cost to ensure they'd be there to get him. The Squire robots are incredibly strong, able to bend metal bats with their bare hands and throw baseballs with enough force to punch a hole clear through solid steel. In addition, the Squires are able to change their shape and appearance to match that of anyone whose appearance they've been allowed to scan. The coach robot is even stronger, able to move faster than the eye can follow and equipped with laser cannons built into its shoulders. They were all destroyed by Ben. Coach Finn is voiced by Fred Tatasciore, who also voices one of the Squires.
Sublimino
Sublimino is an evil hypnotist who uses hypnosis to force people to commit crimes for him. Ben ended up as one of his victims, and Ben's aliens forms proved instrumental in retrieving the necessary parts to build a giant hypnosis machine, allowing Sublimino to control an entire mall full of people. When Sublimino hypnotized everyone in the mall, Ben alone escaped the trance. As Wildvine, he brought down Sublimino and broke his hypnotic spell. Other than his hypnotic powers, Sublimino is a weakling and proved no match for Wildvine, relaying on his slaves to protect him. Sublimino appears in "Midnight Madness" and is voiced by Richard Steven Horvitz.
Thumbskull
Thumbskull, as the name suggests, has a head shaped like a thumb. He also has incredible strength (though inferior to that of Fourarms), but limited intelligence. He is one of Zombozo's three minions. Thumbskull appears in the episode "Last Laugh" and again in "Ghostfreaked Out".
His name is a play on the insult "numbskull", as well as the obvious appearance gag. In "Ghostfreaked Out", it's shown that Thumbskull likes pastries when he eats one from a refridgerator as he is looking for Max and Gwen. Jeff Doucette voices Thumbskull.
Volcanus
Volcanus is a Detrovite (the same species as Technorg) who partners up with Sixsix in order to build a weapon capable of destroying a solar system. Unlike Technorg, he isn't enhanced in any way. He is stopped by Ben and the Galactic Enforcers. Volcanus appears in the episode "The Galactic Enforcers". John DiMaggio voices Volcanus.
Yenaldooshi
The Yenaldooshi is a werewolf-like alien sent by Doctor Vicktor to steal communication equipment from a reservation that Ben, Gwen, and Grandpa Max were visiting in "Benwolf". The Native Americans refer to the werewolf alien as the "Yenaldooshi", which is Navajo for "skin walker". Ben fights against the alien as Wildvine. When Ben is transformed back to his normal self by the Omnitrix, the alien werewolf slashes the Omnitrix, causing the device to download his DNA (signified by its face turning yellow) and gradually changed Ben into its form. In their second battle, the alien appears to be killed by a cave-in, though it is not actually shown dead. The device that it was building was shown coming online at episode's end, its purpose left unrevealed. The Yenaldooshi is revealed to have survived in "The Return", and its device is being used as part of Doctor Vicktor's plan. In the next episode "Be Afraid of the Dark", the Yenaldooshi's satellite gets destroyed when Doctor Vicktor accidently rams Max in the space shuttle into Ghostfreak's machine. It is unknown if the Yenaldooshi survived the explosion of the satellite. Ben's version of this alien is named Benwolf.
Zombozo
Zombozo is a vampire-like clown that feeds on the happiness of others. Dressed in appropriate attire, he stages shows to bring people in and then uses a machine he calls the Psyclown to drain the happiness and life energy from them, leaving them disoriented and sad. In the most extreme cases, it even seems to age people. During all this, his minions strip the town of all its valuables. He was eventually defeated when Ben overcame his fear of clowns and terrorized Zombozo as Ghostfreak by peeling back his skin, causing him to explode in a burst of confetti.
While Zombozo's henchmen reappeared in a future episode, he himself did not. The three indicate that they have not seen the clown since his defeat. His name is a play on both "Zombie" and "Bozo", though he bears some resemblance to The Joker from Batman. Zombozo appears in the episode "Last Laugh", voiced by John Kassir.
