A character subpage for Characters/Ben10Villains.

Originally a famous super-hero operating before Ben even got the Omnitrix, Captain Nemesis ended up causing a fake kidnapping attempt on young star actor Jennifer Nocturne, so he could save her and come back on the scene. After the kidnapping was stopped by Ben, he grew jealous of him, to the point he eventually offered a "friendly competition" between them to see who was the best hero. Ben ended up defeating him, causing Nemesis's jealousy to turn into a grudge, and he upgraded his armor to a dangerous level before attempting to get his revenge on him. He eventually lost all common sense and became a villain.

* AccidentalMisnaming: Nemesis thinks Ben’s name is “Ten Bennyson”. Arguably, this is the first sign that
* AttentionWhore: {{Deconstructed}}; over the course of years, he became this due to not standing the fact people were forgetting him. This ends up leading to his FaceHeelTurn.

* TheDarkSideWillMakeYouForget: Both Ben and Nesmith's Agent hinted that Nesmith was a great hero before, and WordOfGod stated that he had noble intentions when starting out as a superhero. However, years of lavishing the fame and fortune that accompanied the job twisted Nesmith into an AttentionWhore who fears being forgotten and, in turn, ''stages crimes'' that could potentially endanger innocents in order to solve them in order to stay relevant.
* DisproportionateRetribution: He went evil, kidnapped Ben's LoveInterest, pulled out a SadisticChoice and got a fixation on killing him. Why? Because Ben upstaged him and defeated him in a so-called "friendly contest".

* GreenEyedMonster: The major reason for him turning evil was because of his jealousy toward Ben. Ironically, Ben didn't mean to ruin his reputation, and [[BrokenPedestal was actually a big fan of his before he turned evil]].
* FallenHero: He started out as a superhero, but ended up trying to cause fake kidnapping in order to get popular again, and eventually turned into a criminal due to his jealousy toward Ben. Both Ben and his Agent hinted he had been an actually great hero before.

* KickTheDog: [[spoiler:He was one of the few villains in the show to be explicitly shown to assault/battery and have killed human beings. He gave Jennifer's driver a head injury by whacking him with a metal pipe despite the guy already giving him the keys to the limousine. Then at a later point, he even killed an innocent driver just to steal his car, which makes it worse as the innocent driver initially stopped with the intentioned to help.]]

* WouldHurtAChild: In "Computer Games", he put billions of dollars to build a KillerRobot that would ''kill'' Ben, a 16-year old kid.

A corrupt warden who uses the Incarceon in Null Void as a drug operation. He's responsible for the death of Kevin's old mentor, hence why he's targeted by Ultimate Kevin.

* HateSink: Morgg is an [[WardensAreEvil incredibly amoral warden]] with absolutely no redeeming qualities. Not only he killed Kwarrel, but he treats prisoners as slaves and forces them to mine a resource he can sell as a drug.

* WardensAreEvil: An amoral warden who uses Incarcecon for drug trafficking and refuses to let the Plumbers find out.

* {{Flanderization}: Omniverse plays up his elephant like traits, which were near non-existent in Ultimate Alien

* NominalVillain: 775 wanted to break free and get revenge on Colonel Rozum, who kept him prisoner in a POW camp for aliens for decades, without even giving him a chance to explain why he was on Earth. Because of this, he was unable to return to his planet, which was taken by a dictator and his entire family is murdered. He plans to kill Rozum's wife and baby, [[WouldntHurtAChild but he hasn't the heart of doing such a horrible thing]]; instead, he tries to trick Ben into killing him. And, when even that doesn't work, he tearfully begs to be killed, because there's nothing left for him.

* {{Flanderisation}: Omniverse plays up his elephant like traits, which were near non-existent in Ultimate Alien

* KickTheSonOfABitch: Stealing the power of Addwaitya in "Where The Magic Happens".

* KickTheSonOfABitch: Albedo gives this to him.

* EvenEvilHasStandards: He seems to draw a line at mass alien genocide, if only because no spin doctor could make that go over well with the public.

%%* EvilSoundsDeep: He’s got a very deep, gravelly, sinister voice courtesy of Creator/JohnDiMaggio. (Does not describe the "evil" part.)

* CorruptedCharacterCopy: Of [[Franchise/SpiderMan J Jonah Jameson]], being another newsman who uses his platform to slander the resident teen hero. However, while Jameson dislikes superheroes because he doesn't trust masked figures and thinks the heroes should be held accountable for the collateral damage they cause, Harangue is just a fantastic racist who goes after Ben out of FantasticRacism towards aliens, to the point of supporting the Incursean Invasion if it means getting rid of Ben, [[EveryoneHasStandards something Jameson would never do.]]

* {{Expy}}: He's [[Franchise/SpiderMan J Jonah Jameson]] mixed with [[ComicBook/XMen Senator Kelly]] as a TV pundit.

* KickTheDog: [[spoiler:He was one of the few villains in the show to be explicitly shown to assault/battery and have killed human beings. At one point, he even killed an innocent driver just to steal his car.]]
* KnightOfCerebus: By the time of his second appearance, Nesmith's character is completely PlayedForDrama[=/=]PlayedForHorror in the most realistic way possible with him [[spoiler:assaulting and murdering human beings]]. Not only does the entire episode he stars in lacks any sort of comical tone, but the genre narrative is more akin to a "prison thriller" than anything.

* RememberTheNewGuy: Apparently, he was already an active hero long before Ben was even born.

* SelfMadeSuperpowers: While it's ambiguous if he designed his armored battlesuit on his own, or needed the help of others, it doesn't change the fact that he became a superhero through it and was active ''before'' Ben was even born.

* TheDarkSideWillMakeYouForget: Both Ben and Nesmith's Agent hinted that Nesmith was a great hero before, and WordOfGod stated that he had noble intentions when starting out as a superhero. However, years of lavishing the fame and fortune that accompanied the job twisted Nesmith into an AttentionWhore who fears being forgotten and, in turn, fake situations in order to solve them in order to stay relevant.

* EvilIsPetty: His reasons for making a FaceHeelTurn? Because a teenager, who was his biggest fan, gets much more attention than ''him''.

* HumansAreTheRealMonsters: Partway into his second appearance, Ben reflects on Nesmith's casual brutality[[spoiler:, which by this point has included outright murder]]. He's aware that his usual opponents are leagues more dangerous than a human antagonist, but he still finds facing a hate-filled psycho driven by a petty, one-sided grudge to be very disturbing. As Gwen says, humans can be monsters, too.

* NotSoHarmlessVillain: His first episode portrays him as something like a Silver Age superhero parody turned evil, who is rather quickly disposed off. [[spoiler:Come his next appearance, he becomes the first villain to successfully commit homicide in the whole saga.]] ''Omniverse'' undoes this, basically making him an evil parody of Iron Man/Tony Stark.

* PickOnSomeoneYourOwnSize: By the time of his second appearance, he has developed an obsession on taking his revenge on Ben.

* ThatManIsDead: "Captain Nemesis is dead! Now, call me ''Overlord''!". [[SubvertedTrope Although, it doesn't take]], since afterwards they either call him by his real name or Captain Nemesis.

* KnightOfCerebrus: By the time of his second appearance, Nesmith's character is completely PlayedForDrama/PlayedForHorror in the most realistic way possible with him [[spoiler:assaulting and murdering human beings]]. Not only does the entire episode he stars in lacks any sort of comical tone, but the genre narrative is more akin to a "prison thriller" than anything.

* {{Expy}}: His appearance, abilities and characterization owe a lot to ComicBook/IronMan, and some of his stories about his old adventures call to mind the ComicBook/FantasticFour. His name and style, as a whole, are a rather obvious ShoutOut to Silver Age Superheroes.
* GreenEyedMonster: The major reason for him turning evil was because of his jealousy toward Ben. Ironically, Ben didn't mean to ruin his reputation and [[BrokenPedestal was actually a big fan of him before he turned evil]].

* KickTheDog: [[spoiler:He was one of the few villains in the show to be explicitly shown to have killed human beings. At one point, he even killed an innocent driver just to steal his car.]]

* CorruptedCharacterCopy: Of [[Franchise/SpiderMan J Jonah Jameson]].

** Dwight Mcduffie stated on his website that originally he became a superhero to help people.

* ContrastingSequelAntagonist: In contrast to the previous villains of the series, Aggregor is more of an intergalactic threat that seeks to obtain the map of infinity that will allow him to enter the forge of creation and absorb a baby Celestialsapien to [[GodhoodSeeker become a god]] and he is also a lab experiment created by using Kevin’s DNA to recreate the latters powers.

* KarmaHoudini: Pretty much got off scot-free for his actions in "Computer Games"; even with him nearly toppling the ''freaking '''Washington Monument'''''[[note]]which would have easily landed him several consecutive lifetime sentences in federal prison[[/note]], save for the billions he spent on the robot. [[AndThatsTerrible And his car]].

* CaptainErsatz: Is named after a Great Old One, but his characterization heavily borrows from Cthulu.

* {{Cthulhumanoid}}: Though the humanoid part is debatable.

* EldritchAbomination: He's not named after a Great Old One for nothing.
** Just ''looking'' at it in a PensieveFlashback causes Ben, Gwen and Kevin to freak out. Consider what they fight on a daily basis and that says a lot about how horrible it is.

* FantasticRacism: Against aliens. [[{{Hypocrite}} Though that doesn't stop him from siding with the Incursean during their invasion]].

* NeverMyFault: Spending the whole of ''Frogs of War'' vigorously [[TheQuisling kissing the Incursean invaders' jackboots]] has torpedoed his ratings. [[BlatantLies He insists that he was trying to undermine them before Ben ruined everything]], which no-one buys at all, and cannot understand why people think he's the bad guy.

* TheQuisling: Gladly sings the praises of the Incurseans when they exile Ben from Earth. [[KarmaHoudiniWarranty This is what finally turns the general public against him.]]

* KarmaHoudini: Pretty much got off scot-free for his actions in "Computer Games", save for the billions he spent on the robot. [[AndThatsTerrible And his car]].

* MonumentalDestruction: very nearly topples the Washington Monument with his KillerRobot during his fight against Ben; only for Ben as Humongousaur to catch it and set it upright. Following the fight, Will uses ManipulativeEditing to play the video recording in-reverse to make it seem like Ben was slowly lowering the Washington Monument to the ground.
