History Characters / Ben10

* VillainDecay: He could be the poster boy of this trope. Plays by the rules, has a planet of subjects who actually adore rather than fear him, catches a cold at the end of an episode...oh, how the mighty have fallen.

* TookALevelInBadass: In ''Alien Force'', as D'void

* EnemyMine: Helps Ben and his friends against the Highbreed invasion.

** FridgeBrilliance: Then again, he could just be biding his time...

* EasilyForgiven: Only recently, toward the end of ''Alien Force'' and in ''Ultimate Alien'', has any mention been made of his prior characterization ("criminally insane"). However, there were signs of Ben questioning his trust in the first few episodes until he trusted him entirely. Although given that he antagonized Ben for a whole season, you think it would've taken just as long to have Ben forgive him, not just a fraction of a season.

* RetiredBadass: Well, ''formerly'' retired

* ClingyMacGuffin

** WeaksauceWeakness: Vulnerable to water. [[LogicalWeakness Ever turned on a toaster in the bathtub?]]

* CharacterDerailment: Kevin's change from a particularly evil advesary second only to Vilgax himself to an ally/anti-hero might have had a good explanation behind it...but the writers never bothered with one, and his change in character just...happened.

* KarmaHoudini: Though to be fair, the events of "Computer Games" ''did'' result in him losing $170 million and his car.

* EnergyAbsorption: [[WordOfGod Still has it, but no longer uses it]].

* WithGreatPowerComesGreatInsanity: Hinted at. The [[WordOfGod trivia pop-up version]] of his debut episodes hints that his family might have not been entirely unjustified in throwing him out of the house.

** BadAssNormal compared to other Ailens
** CallASmeerpARabbit: Its not a dog it's an eyeless Ape dog cat thing
** DisabilitySuperpower Has no eyes but can "see" with it's other sences

* KarmaHoudini

* EasilyForgiven: Only recently, toward the end of ''Alien Force'' and in ''Ultimate Alien'', has any mention been made of his prior characterization ("criminally insane"). However, there were signs of Ben and Gwen questioning his trust in the first few episodes until they trusted him entirely. Although given that he antagonized Ben for a whole season, you think it would've taken just as long to have them forgive him, not just a fraction of a season.

* ButForMeItWasTuesday: His defeat of Zombozo.
** WordOfGod says he's just acting like that because he doesn't want to admit he's still afraid of clowns.

* HeroWithBadPublicity: though only with adults. Teens and younger kids (maybe even some young adults) seem to think he's absolutely awesome.

* ChaoticEvil

* [[MyNameIsInigoMontoya My Name Is Kevin Ethan Levin]]. YouKilledMyFather. PrepareToDie!

** SharingABody: With Ra'ad. [[IGotBetter He gets better]].

** WeaksauceWeakness: Vulnerable to water.
*** LogicalWeakness: Ever turned on a toaster in the bathtub?
*** [[CompletelyMissingThePoint Soggy]] [[TooDumbToLive Toast?]]

** TheOtherDarrin: Before DeeBradleyBaker took over in ''Ultimate Alien'', Nanomech was voiced by [[BillAndTed Alex Winters.]]

** NoIndoorVoice

** WeaksauceWeakness: The clones all feel each other's pain. If one dies...yeah.

** WhatKindOfLamePowerIsHeartAnyway: At least in Ben's opinion.

* MoralEventHorizon: After Tetrax got him what he wanted, he proceeded to use it on his home planet, for no real reason other than to test the brand new toy he obtained.

* TheOtherDarrin: James Remar, {{John DiMaggio}} in the ''Vilgax Attacks'' video game. Somewhat of a {{Wallbanger}} that Remar was used in the show and not [=DiMaggio=], as the former sounds nothing like Vilgax from the original show, while the latter does an impressive StevenBlum imitation.
* VillainDecay: He could be the poster boy of this trope. Plays by the rules, has a planet of subjects who actually adore rather than fear him, catches a cold at the end of the episode...oh, how the mighty have fallen.

* EvilIsSexy: As Mike Morningstar. As Darkstar, this is subverted horifically.

* ThatManIsDead: There is no more Mike Morningstar. There is only Darkstar!

[[folder: SevenSeven]]

* InformedAbility: Hid Badass status.
* SuspiciouslySimilarSubstitute: They could just call him Six Six, you wouldn't realise.
* UpToEleven: Preety much. "He 11 times stronger than Six Six".
* FashionVictimVillain: He looks like Six Six in pink.
* TheUnintelligible: Just like Six Six.

* AllYourPowersCombined: His immediate goal.

* BigBad: Ultimate Alien

* {{Expy}}: Since by now it's probably too late to connect Kevin's first series characterization with his new one, Aggregor is basically Kevin from the orginal show all grown up: sadistic, merciless, and with the power to absorb energy, complete with his body mutating to accomodate the stolen alien power.

* JeffBennett: Voice for ''Alien Force'' and onward
* NotSoDifferent: He's immature, selfish, cracks jokes at inoppurtune times, but when it comes down to it, he can be helpful... sort of like Ben. This is all the more obvious when he says that he likes Ben for saying that he didn't want to figure it out himself.

* ShallowLoveInterest: Initially; she actually got better overtime.

** TheOtherDarrin: He replaced most of the voice actors of the original series aliens (sans [[StevenBlum Ghost]][[JeffBennett freak]]) that've appeared in the sequel series so far. Probably wouldn't count as this trope should Wildmutt, Stinkfly, or Eye Guy appear as he did voice them in the original series.

* MoralEventHorizon: Quite literatelly averted, and Paradox is the only one with recollection of the timeline in which it happened.

* ComesGreatResponsibility (Subverted)

** KevinConroy

* FredTatasciore: His voice in the original series.

** HeyItsThatVoice: [[{{DCAU}} Batman]] is Bellicus.

* KidHero

** ThisBillboardNeedsSomeSalt: At one point, he drinks an animated "Mr. Smoothie".
