8!! The Plumbers
9An organization that plays a key role in the franchise. What they are exactly are have been somewhat [[DependingOnTheWriter inconsistent]] between the series, but they are overall depicted as an organization dealing with aliens which Max was a part of. They retired a bit before the Original Series started, but have been brought back in the TimeSkip before ''Alien Force''.
10----
11[[folder:In General]]
12* AllThereInTheManual : The Pop Up Trivia in Original Series episode ''The Ultimate Weapon'' gives several background details on the group, such as their founding in the 1700s by the Founding Fathers.
13* ArchEnemy: They used to be this with an alien species called Sludgepuppies. The whole point of "Big Fat Alien Wedding" was to end the conflict by marrying their StarCrossedLovers.
14* AscendedExtra: They have always been important, but in the Original Series, they were essentially a background element used to give Max a backstory and justify some of the non-alien high-tech used in the story. In the sequels, they have a progressively larger role.
15* BigGood: The Magistrata.
16* CardboardPrison: Plumber HQ in ''Omniverse'' is absolutely terrible at keeping its prisoners; villains constantly escape from it, sometimes offscreen (like Psyphon, who got arrested around ''three'' times yet always is on the run again by the next episode he shows up), and when they ''are'' shown escaping (Albedo, Dr Animo and Zombozo), they do it incredibly easily. Lampshaded by Ben in “Something Zombozo Comes This Way” when he and Max discover [[spoiler:Zombozo managed to easily escape and pretend he was still there by leaving a kidnapped Plumber disguised as him, with nobody apparently considering checking him sooner, nor anyone finding it suspicious a Plumber disappeared]].
17-->'''Ben''': "Plumbers HQ ''really'' needs to work on its security system, Grandpa!"
18* ElaborateUndergroundBase: In ''Omniverse'', their headquarters in Bellwood are this.
19* InSeriesNickname: "Red spots" in ''Omniverse'', due to their red-colored badges. Note that this is only the case in ''Omniverse''; their badges were never shown in the Original Series and were portrayed as looking similar to the Omnitrix symbol in the UAF era.
20* TheMenInBlack: In the Original Series.
21* MenOfSherwood: When they aren't falling under PoliceAreUseless, they are this.
22* OrderReborn: As explained in ''Omniverse'', the group was rebuilt during the TimeSkip between the Original Series and ''[[WesternAnimation/Ben10AlienForce Alien Force]]''.
23* PoliceAreUseless: For most of the UAF era, they were pretty useless the few times we saw them, and it was even implied they willingly limited their resources on Earth because [[InsignificantLittleBluePlanet they couldn't afford to waste them on a backwater planet]]. They get slightly better in ''Omniverse'' thanks to Earth becoming an open system and allowing them to operate more freely, but they still tend to be conveniently absent or ineffective whenever they could end the episode quickly (for example, they don't show up at all when Looma's father threatens to blow up Earth in “Many Happy Returns”), villains manage to easily infiltrate their HQ several times despite all the security systems, and [[CardboardPrison their prison still somehow fails to keep criminals like Psyphon contained for a long time]]. Also, they recruited [[TooDumbToLive Blucik and Driba]] as their technology expert.
24* RetCon: In the Original Series, they were portrayed as a mostly human secret organization that dealt with the paranormal. In the sequels, they are portrayed as a space police where most members are aliens.
25** They were also explicitly stated in ''Ultimate Alien'' to only deal with aliens to the point they couldn't get involved in arresting supervillain King Vicktor due to him being originally human; in ''Omniverse'', they are seen dealing with some non-alien villains such as Doctor Animo and Billy Billions (who are both full-blood humans) and Zombozo (who has been confirmed by WordOfGod to be a ''supernatural'' being).
26** WordOfGod is that there were ''two'' separate groups of Plumbers, the Earth-based [[TheMenInBlack Men in Black]] of the Original Series and the SpacePolice of the sequels, with the remnants of the Earth group merged into the larger organization at some point before the start of WesternAnimation/Ben10AlienForce
27* RetiredBadass: In the Original Series, most Plumbers we get to see are retired members who stopped their activities long ago, but still have plenty of skills and alien tech at their disposal.
28* ShoutOut: Their armors in the Original Series were very reminiscent of [[WesternAnimation/TheRealGhostbusters the Ghostbusters]].
29* SpacePolice: In ''Alien Force'' onward.

32[[folder:Magister Patelliday]]
33-> Voiced by Creator/RobPaulsen
34[[quoteright:139:https://static.tvtropes.org/pmwiki/pub/images/139px-Patelliday_5642.png]]
35%%[[caption-width-right:139:]]
36
37A Pisciss Volann (Ripjaws' species) Plumber, and the second-in-command of the Plumbers on Earth.
38----
39* AscendedExtra: He appeared for the first time as a cameo character in ''[[WesternAnimation/Ben10UltimateAlien Ultimate Alien]]'' episode "The Mother of All Vreedles". ''WesternAnimation/Ben10Omniverse'' makes him the second-in-command of the Earth' Plumbers and a recurring character.
40* BadassInDistress: In "Gone Fishin'", he is captured by SpacePirates who attempt to serve him to their captain as lunch. Max display limited concern, insisting Patelliday can handle himself on his own. He indeed escapes easily before they arrive: the only reason he was staying as a prisoner was to better figure out what the pirates were up to.
41* CrouchingMoronHiddenBadass: His appearance and mannerisms are much less impressive than Ripjaws, and he seems like a comical character at the first approach, but much like Max, he is more than meet the eyes, as proven in "Gone Fishin'" and "The Rooters of All Evil".
42-->'''Phil''': Aren't you getting a little long in the tooth?
43-->'''Patelliday''': You tell me. (bites him)
44* MauveShirt: Is one of the few named Plumbers outside of Max and the main cast and he reappears quite frequently (compared to the other magisters: Labrid and Gilhil).
45* MoreTeethThanTheOsmondFamily: It’s not as obvious as for Ripjaws, but still visible.
46* NumberTwo: To Max.
47* RememberTheNewGuy: He has been introduced in ''Ultimate Alien'' only, but both a conversation between Max and him and a a comment from Phil suggest that he was there before the Plumbers disbanded before the Original Series, and might even have been the first alien Plumber to operate on Earth.
48* ShoutOut: His voice is a homage to comedian Creator/DonKnotts, who starred in ''Film/TheIncredibleMrLimpet'' as a man who becomes a fish.
49* SuperNotDrowningSkills: As a Pisciss Volann, he can breathe underwater.
50* TrueCompanions: It's not given too much focus throughout the series, but he and Max have a great deal of trust in each other and are loyal friends. Phil taunts Max during the Rooters arc about his various partners that ended up either betraying him or dead, but it's clear Patelliday has always got his back.
51* WeaksauceWeakness: Averted; according to WordOfGod, his suit includes systems that allow him to stand out of water without dehydrating like his species usually does. Still a problem in the season 3 finale, where a month in captivity with minimal water is enough to overwhelm the suit.
52** Sustained high temperatures can also be a problem, as shown in "Clyde 5," where Vera Tennyson cranks up the heating of Plumber [=HQ=], leaving Patelliday almost completely dehydrated in a matter of minutes.

60A Plumber officer, and one of Max's friends. He shows up in ''[[WesternAnimation/Ben10AlienForce Alien Force]]'''s pilot episode to investigate the Highbreed invasion and help Ben find Max. [[spoiler:He gets killed, and leaves to Ben the mission to end the invasion]].
61----
62* AlienBlood: If his "that's not water" is to be taken at its direst, his species has neon blue blood that steams on contact with at least Earth's atmosphere.
63* BerserkButton: Magister Labrid takes the usage of alien technology very seriously. Seeing Forever Knights trading Level 5 tech and beyond that by all rights shouldn't be on Earth seemed to make him snap, causing him to break his cover and declare all the Forever Knights and the [=DNAliens=] they're dealing with to be under arrest.
64* ConspicuousTrenchcoat: Magister Labrid's human disguise wears one of these, along with a form-fitting hat.
65* HeroicSacrifice: [[spoiler:He ends up damaging his suit while saving Kevin from a sure death, leading to his own demise.]]
66* KilledOffForReal: [[spoiler: He dies towards the start of the ''second episode'' of ''Alien Force'' [[EstablishingSeriesMoment to show that the stakes are considerably higher than when Ben was ten.]]]]
67* MistakenForThief: He initially pursues and antagonizes Ben and Gwen because he suspects them for stealing the Omnitrix for petty reasons. After he's informed that they are Max's grandchildren, Magister Labrid offers a sincere apology and offers to work with Ben and Gwen to find their grandfather and help save Earth from the Highbreed.
68* NoBodyLeftBehind: [[spoiler:His body dissolves after his death, leaving only his Plumber suit. Possibly justified because of his BizarreAlienBiology.]]
69* ReasonableAuthorityFigure: Except for the short part at the beginning where he mistook Ben for a thief, he is fairly reasonable as far as Plumbers go.
70* SacrificialLion: He is killed in the second half of the ''Alien Force'' premiere to establish just how dangerous the Highbreed truly are.
71* SmallRoleBigImpact: He appears in two episodes, not counting a very short cameo in a later flashback episode, and [[spoiler:dies at the end]]. In this short time, he directed Ben and his friends toward fighting the Highbreed Invasion and partially initiated Kevin's HeelFaceTurn. Furthermore, his relationship with Max Tennyson is how he gets to know Ben and Gwen as allies, and get them attuned to the [=DNAlien=] conspiracy.
72* WeaksauceWeakness: He needs his suit to survive on Earth. [[spoiler: A rupture that not only exposed his flesh but also left a gash in him caused him to die of exposure.]]
73* WeHardlyKnewYe: [[spoiler: He gets killed an episode after his debut, but we do get to find out more about him in a flashback.]]

78[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/300px-magister_prior_ghilhil_2194.png]]
79
80The Plumber officer in charge of the sector where Earth is located during the UAF era.
81----
82* BackForTheDead: [[spoiler:He comes back in ''Ultimate Alien'' only to be killed by Aggregor.]]
83%%* BadassNormal
84%%* ByTheBookCop
85%%* CoolHelmet
86* FourStarBadass: In this case '' Magister Badass''; the Officer in charge of the entire sector. Also a pretty good fighter capable of easily defeating Kevin.
87* GenreBlind: While you can't blame him for being skeptical about the Highbreed invasion due to not having any proof, he doesn't even bother ''investigating'' himself to make sure. He also doesn't both to check the source of his tip to make sure he isn't walking into a trap.
88** He gets better by ''Ultimate Alien'', where, when receiving a distress call from Aggregor's ship and being given a flimsy excuse by Aggregor to justify it, he decides to still give it a look just in case. [[spoiler:Sadly, [[DeathByGenreSavviness this ends up costing him his life]].]]
89* JerkAss: Comes out like this in "Darkstar Rising", where he attempts to arrest Ben's team for supposedly passing themselves as Plumbers, flat out states [[PoliceAreUseless the Plumbers can't afford to waste their resources on backwater planets like Earth]] and refuses to listen or investigate about their claims about the Highbreed invasion is going on. He, fortunately, gets better by the end of the episode.
90* KilledOffForReal: [[spoiler:By Aggregor in ''Ultimate Alien''.]]
91* MirrorCharacter: To Magister Labrid. Both of them are Plumbers who primarily operate in the Earth sector of the universe, and end up dying while trying to investigate threats to the universe. However, while Magister Labrid was a loyal friend to the Tennysons who was more than willing to inform and help them regarding the [=DNAlien=] conspiracy, Gihil initially was an Inspector Javert who blocked Ben from doing the right thing until irrefutable evidence was presented to him.
92* TheWorfEffect: In ''Alien Force'', Gihil was able to hold his own against the main trio, and helped take down Darkstar. In ''Ultimate Alien'', he's instantly killed by Aggregor the second he starts investigating his ship, demonstrating just how dangerous the latter is.

99A Plumber introduced in the ''Film/Ben10AlienSwarm'' movie, and Elena's father.
100----
101* BrainwashedAndCrazy: Courtesy of the Hive.
102* CassandraTruth: [[spoiler:He ''tried'' to warn the other Plumbers about the sentience of the Hive, but wasn't listened to.]]
103* DroppedABridgeOnHim: [[spoiler:Dies in the time between ''Alien Swarm'' and ''Ultimate Alien''.]]
104* KilledOffForReal: [[spoiler:In ''Ultimate Alien''.]]
105* LargeHam: In ''Alien Swarm'', while controlled by the Hive.
106* MadScientist: [[spoiler:Subverted; he was believed to be this, but his actions actually had a really sane motive.]]
107* PosthumousCharacter: [[spoiler:In ''Revenge of the Swarm''.]]
108* RedHerring: The beginning of ''Revenge of the Swarm'' sets him up as the main antagonist for the episode. [[spoiler:He actually was dead in the time between ''Alien Swarm'' and that episode; the real villain is Elena, possessed by the Hive.]]
109* ShaggyDogStory: [[spoiler:Ben goes through a lot of trouble in ''Alien Swarm'' to defeat the Hive without having to kill him... only to have him die anyway in ''Revenge of the Swarm''.]]

115[[caption-width-right:320:[[GeniusDitz The two dumbest geniuses in the Milky Way Galaxy, ladies and gentlemen!]]]]
116
117A duo of Galvans introduced in ''[[WesternAnimation/Ben10Omniverse Omniverse]]''. The two of them are tech support in the Plumbers' HQ, in charge mostly of machines. Though they possess advanced knowledge in technology like all Galvans, they are incredibly dumb when it comes to practically everything else.
118----
119* AliensSpeakingEnglish: While that is very obvious in this universe, they are able to ''write'' in English, albeit poorly spelled. During their first time on Earth, they facilitated the needs of Translators in order to communicate with humans, but in the present day, they have no need for such.
120* AreYouPonderingWhatImPondering:
121-->'''Driba:''' Are you thinking what I'm thinking?
122-->'''Blukic:''' I hope not.
123* AttentionDeficitOohShiny: in one episode, they are distracted by a Mr Smoothie commercial while Ben and the other Plumbers are dealing with a crisis.
124* BeenThereShapedHistory: They were the aliens that crashed near Roswell.
125* BigGuyLittleGuy: They're both pint-sized, but by Galvan standards, Blukic is tall while Driba is short and squat.
126* TheEngineer: They serve as the Plumbers' tech support, although they momentarily forget they were tech support.
127* FantasticRacism: They seem to have it out for Cerebrocrustaceans, as they have been known to make unpleasant comments about the species at least twice in the show.
128-->'''Driba''': "We are not Cerebrocrustaceans; [[BlatantLies we know what we are doing]]."
129* FatAndSkinny: Driba is visibly chubbier than the typical Galvan while Blukic is distinctively lankier.
130* GadgeteerGenius: For all the common sense they lack, their technical genius is still far greater than a human's and they can rig advanced technology on the fly with ease, such as Trombipulor's robotic mice.
131* GeniusDitz: While they have the natural intelligence that comes with Galvans, they are very stupid for their species. They are smart enough to repair the Omnitrix when a piece is missing in "Outbreak", albeit after several failed attempts. In "Catfight", they also created a remote control for the Omnitrix. However, in "Evil Encore" they make an emergency exit in the ventilation shaft, but are too stupid to make it bigger than Galvan height. Tellingly, they can't even ''spell'' several English words properly, while an average Galvan can become proficient in written and spoken English in half the time they did.
132* JokeCharacter: Mostly there for comic relief.
133* TheLoad: Safe for a few times where they actually prove useful, they tend to mostly make things worse for the Plumbers and their stupidity almost killed the heroes at least twice. You ''seriously'' come to wonder why they even keep them around.
134* {{Metaphorgotten}}:
135-->'''Driba:''' Like {{Icarus|Allusion}}, we flew too close to the sun. And like Icarus, [[{{Metaphorgotten}} we never got our smoothies]]...
136* NiceJobBreakingItHero: They ''fixed [[DoomsdayDevice the Annihilargh]]''.
137* NoodleIncident: When the two get eaten by a humongous alien elephant supervillain, Blukic mentions "this is the second-worst time I've been stuck in an elephant's mouth." We never find out what the first was.
138* NormalFishInATinyPond: Dumb by Galvan standards, geniuses by Earth standards. Unfortunately for the Plumbers, they're usually the only Galvans available.
139* PercussiveMaintenance: Blukic fixes things by hitting them with a wrench. Surprisingly, this actually seems to be some of his most effective repair work.
140* RememberTheNewGuy: They were first introduced in ''Omniverse'', but they had allegedly been around the whole time even though we had never seen them. Flashbacks in-between the original series and ''WesternAnimation/Ben10AlienForce'' inject them into the continuity even though there was never any mention of them. The real kick is they had been on Earth since Max was young and were actually the first aliens to officially make contact with humans, being the [[RoswellThatEndsWell alien captured during the Roswell Incident]].
141* ShorterMeansSmarter: Well... [[GeniusDitz supposedly at least]]. As Galvans, they stand about six inches tall, and are technically geniuses in terms of pure scientific knowledge; they're just very, very lacking in common sense.
142* SkewedPriorities: They apparently consider getting smoothies to be more important than possibly being demoted.
143* SmallNameBigEgo: They have a tendency to flaunt their genius intelligence to anyone who questions them, even though they're much dumber than other Galvans and have made countless blunders in their work.
144* TheSmartGuy: They're Plumber tech support and have more technical knowledge than anyone else in the organization, but they tend not to use it in a very practical manner.
145* ThoseTwoGuys: They are almost never seen apart, and the one time they are, they greatly miss one another.
146* TooDumbToLive: Practically ''everything'' they do; they abandon the Plumbers during a major crisis to go get Smoothies, somehow repaired a DoomsdayDevice capable of destroying the universe, and built Galvan-sized doors in a base meant for humans and other alien species. It's practically a miracle they haven't been fired already for their incompetence.
147* {{Tuckerization}}: They are named after storyboard artists and directors Butch Lukic and Dan Riba.
148* VitriolicBestBuds: They're best friends, but are always childishly bickering in almost every appearance. Expect at least one exchange of "No, it isn't!" "Yes, it is!" in any episode they have speaking roles.

151[[folder:Lucy Mann]]
152[[quoteright:307:https://static.tvtropes.org/pmwiki/pub/images/lucy_ov_2732.png]]
153[[caption-width-right:307:Psyche!]]
154->Voiced by Creator/TaraStrong
155
156Lucy is a Lenopan (which is usually referred to as a "[[FantasticSlur Sludgepuppy]]"), a species of shapeshifting sludge aliens, and Ben and Gwen's cousin-in-law. She is the cousin of Joel Tennyson's wife, Camille Mann. While she mostly uses her powers for espionage like things, she is fully capable of kicking ass.
157----
158* AnnoyingLaugh: Her laughs are often accompanied by a snort.
159* AscendedExtra: She only appeared once as a ''very'' minor character in the original series via the episode "Big Fat Alien Wedding" (in fact, she had only two scenes that barely last two seconds and wasn't even the main focus of said episode). In ''Omniverse'' (both in the flashbacks and present), she is shown to have hung out a lot with Ben and Gwen as kids in the flashbacks and she joins the Plumbers five years later, being the first Sludgepuppy to do so, and gets a whole episode dedicated to her.
160* BlobMonster: Lucy's full Sludgepuppy form is a benevolent example.
161* BlondeBrunetteRedhead: As for the most prominent female Tennyson cousins, she's the blonde, while Sunny's the brunette and Gwen's the redhead.
162* CharacterCatchphrase: "Psyche!"
163* CuteMonsterGirl: Played with, in a more subtle way than the Original Show. In "Big Fat Alien Wedding", [[BeautyEqualsGoodness Camille's evil mother had a classic monstrous Sludgepuppy form, while Camille herself had a more humanoid, attractive one]]. Lucy in "Mud Thicker Than Water" shows the ability to use both variants.
164* TheCutie: Due to her very cheerful and well-intentioned disposition, it's easy to forget that she can be a troublesome girl, especially towards Gwen.
165* DarkIsNotEvil: Her attires in both her preteen and teenage versions heavily consist of the color black, but even though she's fond of pranking others (most notably, Gwen), she's far from being heartless, as well.
166* TheGadfly: Likes using her powers to trick people, especially Gwen.
167* GenkiGirl: Not much removes the smile from her face, and even a fight won't stop her from pranking people.
168* HairOfGoldHeartOfGold: As unpredictable as she may be (partially due to her shapeshifting powers), her good-natured streak will always be there.
169* LawyerFriendlyCameo: In the original series, she looked like Franchise/{{Naruto}}'s female form, whisker marks and all.
170* MeaningfulName: Her name means "light," which befits her consistently sunny personality.
171* PerpetualSmiler: She often smiles, even in the most dire of situations.
172* RedHerring: [[spoiler:”Mud is Thicker than Water” is set up to make her seem like TheMole. In reality, she was TheMole hired to help discover the real mole, a Tetramand named Gorvan.]]
173* RedIsHeroic: Both of her attires in her preteen and teenage selves contain the color red, and is part of the Plumbers who fight against serious enemies.
174* RedOniBlueOni: The ever so excitable Red Oni to Gwen's more level-headed Blue Oni, to which this trope even applies to them literally when considering their respective signature colors.
175* TheReveal: Her being a Sludgepuppy in the original series as it is easy to forget she came from the bride's side of the family in addition to her short screen time. It's only until the end this was showcased when Ben ends up slipping on her sludge while trying to dance with her at the reception.
176* {{Shapeshifting}}: Apparently, Ben is not the only shapeshifter in the family.
177* TokenHeroicOrc: Sludgepuppies were best-known for being the Plumbers' [[ArchEnemy sworn enemies]] for years. She is the first of them to join their ranks. Though to be fair, by the point she joins, the war between the two has been over for around six years.
178* TomboyAndGirlyGirl: Lucy is the Girly Girl to Gwen's Tomboy
179* {{Troll}}: A RunningGag in "Mud is Thicker than Water" is pranking Gwen with her shapeshifting. "Psyche!"

185
186A cowardly insect-like alien, and member of the Plumber's Alpha Squad, who first appears in "Vilgax Must Croak", and later joins Ben, Rook, and Rad Dudesman in their trip to the Anur System.
187----
188* ButtMonkey: Most of his appearances involve him being placed in scary situations (from visiting [[{{Halloweentown}} Anur Transyl]] to escorting [[TheDreaded Vilgax]]), shot at, attacked or otherwise mistreated. Ben even considers him like a RedShirt.
189* CowardlyLion: Despite his cowardice, he's somehow a member of the Alpha Squad.
190* DeadpanSnarker: As cowardly as he is, he's prone to this.
191-->'''Whampire''': I got a planet full of monsters after me, an alien vampire just turned my friends into puppets, and my appetite is really weird!
192-->'''Hobble''': I noticed that when you were about to ''eat'' me!
193-->'''Whampire''': More like [[OurVampiresAreDifferent I was gonna drain your energy]].
194-->'''Hobble''': Oh yeah, ''[[SarcasmMode so much better]]''.
195* HopelessSuitor: He had a crush on Charmcaster.
196* InsectoidAliens: His design is somewhat bug-like.
197* RedShirt: Even wears red armor. However, it's downplayed since he doesn't die, but he is a ButtMonkey, and Ben even calls him a "red shirt" in “Rad Monster Party”.
198* UglyGuyHotWife: WordOfGod says that [[HotWitch Charmcaster]] and [[InsectoidAliens Hobble]] will be married in the future. [[https://static.wikia.nocookie.net/ben10/images/1/19/Hobble_and_Charmcaster_Will_Be_Married.png/revision/latest?cb=20200920062041 It's true.]]

205A Loboan Plumber operating on Anur Transyl, and one of Rook's former classmates. He serves as their ally during their visit to Anur Transyl in the ''Galactic Monster'' story arc.
206----
207* AscendedFanboy : Much like Rook, he read a lot about Ben while studying in the Plumber Academy, and was inspired by him into becoming a Plumber.
208%%* DarkIsNotEvil
209* MySpeciesDothProtestTooMuch: He doesn’t share the FantasticRacism most of Anur Transyl’s inhabitants have toward outsiders, and in fact calls them out for it when they act hostile toward Ben.

221* EyepatchOfPower: A FreezeFrameBonus in "End of an Era" shows her in Ben 10,000's time with a patch over her right eye.
222* MauveShirt: Despite wearing red she's long-lived and gets some characterization.
223* NoCelebritiesWereHarmed: Resembles and has a name similar to Creator/HollyHunter.
224* RecurringExtra: She plays no major role in the story, but frequently appears as a background character.
225* TokenGoodTeammate: Previous Alpha Squad members were shown to be smug jerks. Molly is none of these things.

233* BadassAdorable: Manages to be cute and competent at the same time.
234* NonStandardCharacterDesign: Her head is more triangular than other Galvans.
235* OfficialCouple: With Driba.
236* OnlySaneMan: Compared to Blukic and Driba, she's much more mature than them.
237* TookALevelInKindness: The next time we see her, she's more tolerable of Blukic and Driba's antics and doesn't show any slight annoyance of them. This may have to do with the issue about the Skeuomorph being resolved.
238* {{Tuckerization}}: Named after writer Len Uhley.

241[[folder:Principal Edward White]]
242--> '''Played by''': Creator/RobertPicardo
243
244A Plumber officer in Ben's hometown who only appears in the AlternateContinuity live action-film ''Film/Ben10RaceAgainstTime'', and possibly in the original series finale (which is set in a different alternate universe), where a teacher at Ben's school resembles him.
245----
246* BadassTeacher: He's a principal who works for a [[TheMenInBlack Men in Black]] group and helps fight the villain Eon.
247* ReasonableAuthorityFigure: He initially seems like a SternTeacher who won't listen to Ben's side of a story about a fight. Later, he apologizes for this, telling Ben it was to keep his cover intact, and from then on he's accessible to Ben as both the principal and a Plumber.
248* SkewedPriorities: White gets some CasualDangerDialogue during a gunfight over a piece of potentially apocalyptic technology. He describes how he tells the keys on his key ring apart and then worries about how to replace a lock after one of his colleagues gets impatient with him and smashes the lock.
249[[/folder]]

251[[folder:Wes Green]]
252--> '''Voiced by''': Miguel Nájera
253
254Kai's grandfather, and an old colleague of Max's.
255----
256* TheBusCameBack: After his debut early in season 3 of the original show, he never reappears until ''Omniverse.''
257* EntertaininglyWrong: He's convinced the Yenaldooshi is a Navajo spirit out to destroy technology due to feeling it defiles the land. Actually, his adversary is an alien who is stealing technology to make a transmitter device.
258* NiceGuy: StayInTheKitchen moments aside, he's a caring grandparent to Kai, is happy to see his old friend Max again when the Tennysons visit the Navajo reservation, and takes Ben and Gwen's contributions seriously.
259* RetiredBadass: Wes seems like a normal retiree until he casually compares chasing the yenaldooshi to a time he and Max pursued a yeti through the Himalayas.
260* StayInTheKitchen: He initially makes Kai and Gwen sit out the hunt for the yenaldooshi due to saying that only braves are supposed to be trackers and "times change but traditions don't." He does allow them to contribute later on, though, and is fighting evil aliens along with Kai by the time of ''Omniverse''.

272-> Sandra played by Creator/TaraStrong (Original Series, ''Destroy All Aliens''), Beth Littleford (''Race Against Time'', ''Alien Force'', ''Ultimate Alien'', ''Omniverse''), Vyvam Pham ("Ben 10 Returns, Part 1")
273
274Ben's open-minded parents.
275----
276* AlmightyMom: Compared to her more easy-going husband, Sandra is the more authoritative of the two. She even has the guts to talk down Ma Vreedle, an often-feared criminal, and intimidates Ben with a 'look' when he tries to do heroics under their nose.
277* AmazinglyEmbarrassingParents: Invoked. They're the stereotypical [[GranolaGirl Granola Couple]].
278* BadassBystander: Upon finally accepting Ben is a hero, Carl and Sandra go to assist him, with Carl grabbing an alien rifle Max left behind and [[DidYouJustPunchOutCthulhu blasts a Highbreed across the room]]!
279* BigOlEyebrows: Carl inherited these from his father, Max, and passed them onto his son, Ben.
280* CanonImmigrant: Added to the cartoon after debuting in ''Race Against Time''.
281* {{Cloudcuckoolander}}: In ''Omniverse'', Sandra get a visit from Princess Looma trying to deliver her wedding gifts to marry her son; said gifts include Rook, Esther, Julie, and one of Fistina's arms. And then Ben and Fistina arrive to fight Looma right at her front door. She spends the entire scene watching this completely insane situation and treating it [[UnusuallyUninterestingSight like if it was completely normal]]. Then again, she is [[WeirdnessMagnet Ben's]] mom [[SeenItAll so...]]
282* DependingOnTheArtist: In the original series and ''[[https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTX1wvy9-BSreqv4la8H6Dlks0qPgmV3e6sfg&usqp=CAU Destroy All Aliens]]'', both Carl and Sandra [[https://is1-ssl.mzstatic.com/image/thumb/5S1P19ICLVdfRuFYjWZ2iw/1200x675.jpg look more youthful with Carl's hairstyle looking closer to adult Ben's]]. In ''Film/Ben10RaceAgainstTime'' and ''Alien Force'', [[https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTfxQLETrzaAOl-UWgjK211ffKc1CM6NTbB3g&usqp=CAU they look more like]] [[https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcR1RFdjoTtJiUcWwmudlvUn2R2QBgl0iherVg&usqp=CAU the actors who played them]] in ''Race Against Time''.
283* DotingParent: Both tend to do this, but Sandra arguably takes it a bit further.
284* DumbBlonde: Subverted with Sandra; see ObfuscatingStupidity.
285* EarlyInstallmentWeirdness: They initially appeared in a WhatIf episode of the Original Series with completely different designs, before being given the movie designs in ''Alien Force''.
286* HiddenDepths: In both the Original Series and ''Alien Force'', it's mentioned Carl resents Max for neglecting the family in favor of Plumbers matters and, when he learns about the Omnitrix, for involving Ben in it. He gets better.
287** While we don't see his reaction, based on how his brother (Gwen's father) reacts to seeing Verdona Tennyson (their mother), it's implied that both Tennyson brothers have mixed feelings toward Max and Verdona.
288%%* HippieParents
289* LethalChef: Not really, but Ben doesn't like Sandra's cooking. Rook does, though.
290* LockedOutOfTheLoop: Excluding a non-canon episode from the Original Series, they didn't learn about Ben's super-heroics until around the middle of ''Alien Force''. They initially reacted badly ([[YouAreGrounded by grounding him]], in fact), but eventually allow Ben's duties as a hero.
291* NiceGuy: Despite being unaware of his antics at first, Ben's parents are kindhearted, protective, caring, loving and compassionate, especially Sandra.
292* ObfuscatingStupidity: Downplayed in the Original Series, but ''Alien Force'' shows they are much smarter than they appear to be; when they find out about Ben's heroics, it disturbs them so much that they easily foil any attempt from him to leave without their knowledge or communicate with Kevin and Gwen, eventually forcing him to just transform and force his way out.
293* OddFriendship: Sandra has one with ''Ma Vreedle'' in ''Omniverse''.
294* PutOnABus: Carl doesn't appear in ''Omniverse'', even though his wife is a recurring character.
295
296!!Frank and Natalie Tennyson
297-> Frank played by Creator/GeorgeNewbern
298-> Natalie played by Creator/JulietLandau
299
300Gwen's conservative parents.
301----
302* BigOlEyebrows: Frank inherited these from his father, Max.
303* FreudianExcuse: It's implied Verdona's free-spirited and irreverent nature and abandonment of Frank is the reason Frank is so conservative and straight-laced as an adult.
304* ObnoxiousInLaws: Natalie really doesn't care for her mother-in-law even before Verdona tried to abduct Gwen and take her back to her home planet. When Verdona says she'll be checking back on Gwen, Natalie's response is a ''very'' deadpan, "Oh, joy."
305* SiblingYinYang: Frank is more conservative and less excitable than his slightly New-Age brother as shown in their reactions to discovering their children's secrets: Carl flips out when he finds out about Ben's Omnitrix while Frank resignedly accepts Gwen's powers will bring his mother back into their lives (although he, like Carl, [[EveryoneHasStandards grounds Gwen]] when he finds out she's been helping Ben fight the Highbreed).
306* StrongFamilyResemblance: [[https://vignette.wikia.nocookie.net/ben10/images/6/6a/Natalie_Profile.png/revision/latest?cb=20180923022807 Natalie]] looks like an older version of her daughter. Frank also resembles his brother strongly to a lesser extent.
307* UnreliableExpositor: Frank claims that magic doesn't exist. Safe to say he was rather wrong about that.
308
309!!Ken Tennyson
310-> Voiced by Creator/WillFriedle
311
312Gwen's older brother.
313----
314* AllThereInTheManual: Ken's existence was first verified in Pop-Up Tria entry in the Original Series episode "Lucky Girl" which established him as Gwen's older brother and that Ben looked up to him.
315* ChuckCunninghamSyndrome: Remembered by fans for this reason. He never appeared or gets mentioned again after his debut episode.
316* RememberTheNewGuy: While Gwen having a brother was part of the series bible since the Original Series, outside of the one trivia entry, Ken was never mentioned before and it was never suggested in-show that Gwen had siblings. The fact that he never appears or gets mentioned after his debut doesn't help.

323
324[[quoteright:270:https://static.tvtropes.org/pmwiki/pub/images/Cash_y_JT_2119.jpg]]
325
326A duo of bullies who used to bother Ben in the original series, typically by hanging him to trees. Once he got the Omnitrix, Ben developed a liking to giving them a payback.
327----
328* TheBully: In the ''Original Series'' and briefly in ''Alien Force''.
329* ButtMonkey: Whenever they appeared in the original series, Ben found the time to give them a mega-wedgie. Even worse in ''Alien Force'' and ''Ultimate Alien'', where they even lost their bully status due to [[TookALevelInBadass Ben no longer being someone to bully]].
330* CantTakeCriticism: Cash did not take Ben's [[NotAfraidOfYouAnymore speech]] telling him to grow up and get a life with any amount of maturity.
331* CreepyChild: Invoked with [[EeriePaleSkinnedBrunette pale-skinned black-haired]] Cash.
332* ADayInTheLimelight: “The Gauntlet” and Reflected Glory”.
333* EmpoweredBadassNormal: Cash ends up fusing with a Techadon gauntlet able to take on Ben.
334* EvilIsPetty: Cash takes Ben's TheReasonYouSuckSpeech in "The Gauntlet" personally, leading him to trash Kevin's car in retaliation.
335* GoodCounterpart: While they aren't seen, their counterparts in No-Watch Ben's universe are Ben's closest friends.
336* {{Guyliner}}: Cash looks like he's wearing them, but it's not clear whether or not he actually does.
337* IneffectualSympatheticVillain: Particularly in ''Alien Force'' onwards. In the one episode Cash manages to become a genuine villain by merging with Techadon tech, all he accomplishes is defeating Kevin, before failing to even inflict a single scratch on Ben.
338* OpaqueNerdGlasses: JT is never seen without them.
339* TheReasonYouSuckSpeech: Courtesy of Ben in "The Gauntlet." After they spill a smoothie on him as a prank, he chides them for pulling the same nonsense since grade school and admits disbelief that he used to be afraid of Cash. Though JT took it in strides but Cash [[EvilIsPetty took it personally]].
340-->'''Ben:''' You know what? You two aren't even [[NotWorthKilling worth it.]]
341-->'''Cash:''' Huh?
342-->'''Ben:''' It's ridiculous! Could you at least try being original for a change? You've been doing the same old bully routine since the Second Grade, Cash. It's tired. Spilling my drink? Seriously? [[NotAfraidOfYouAnymore I can't believe I used to be afraid of you.]] Look around, Cash, we've all grown up. But you're still the same pathetic loser that has to torment others to feel good about himself. You're just sad.
343* SchoolyardBullyAllGrownUp: Attempted by Cash in ''[[WesternAnimation/Ben10AlienForce Alien Force]]'' episode "The Gauntlet". This... [[NotAfraidOfYouAnymore wasn't very successful]].
344* SitcomArchNemesis: To Ben in the Original Series; he hates them, but they are little more than school bullies who hardly are a threat.
345* ThoseTwoGuys: They're rarely seen without each other.
346* TooDumbToLive: Aliens tend to show up whenever Ben is around and put Cash and JT in their place when danger follows him. Even without the Omnitrix, in ''Alien Force'' Ben's so skilled and versatile from literal years of battle and heroism that he'd wipe the floor with Cash. Plus [[TheBigGuy Kevin]] is present, and totally ready to can the bully duo just because he personally hates them that much. Cash ''still'' tries to [[BullyingADragon push around and bully]] Ben despite all of this yet again, and it actually shows CharacterDevelopment for ''Ben'' to not just respond with LaserGuidedKarma in kind.
347* TookALevelInKindness: JT has mellowed out by ''Ultimate Alien''.
348* WeUsedToBeFriends: JT used to be friends with Ben until deciding to remain on Cash's good side.

351[[folder:Azmuth]]
352!Azmuth
353-> Voiced by Creator/RobertDavidHall (Original Series, ''Destroy All Aliens''), Creator/JeffBennett (''Alien Force'', ''Ultimate Alien''), Creator/ReneAuberjonois (Omniverse)
354
355[[quoteright:224:https://static.tvtropes.org/pmwiki/pub/images/946541_1328618147641_full_6749.jpg]]
356%%[[caption-width-right:224:]]
357
358The brilliant, if [[CynicalMentor cynical]] and [[InsufferableGenius obnoxious]], creator of the Omnitrix. A Centuries years old Galvan (Grey Matter's species) considered as the smartest being in three galaxies, Azmuth created the Omnitrix as a means to allow all species to be in each other shoes and better understand each other, and as by this way promote peace. As such, he was disgusted when people like Vilgax attempted to use it as a weapon, becoming disabused with the Universe. After Ben proved to him the Omnitrix could still be used for good however, he got back part of his hope in the Universe and started to act as one of Ben's Mentor.
359----
360* AboveGoodAndEvil: He had two variations of this over the course of the series:
361** In the original series, he only wanted beings from the universe to understand each other to create peace, and the use of the Omnitrix as a weapon by one person was the same as another, and the sides and reasons did not matter.
362** Afterwards, his dedication became to the universe, and sees the universe as it is, as Albedo found out--The battles between good and evil within the universe are petty and insignificant. The ambition of those who are "evil" is ultimately pointless, as to tear down and destroy is of no consequence or quality.
363** Maltruant also states that regardless of the time or dimension, Azmuth is always too smart to be evil, which is why in order to get himself repaired, he had to settle for the second smartest being in the galaxy, Dr Psychobos.
364* TheAtoner: [[spoiler:He once created the Ascalon sword, a weapon so powerful it caused the destruction of the Incursian home planet after one of them tried to use it to unify his species. This is partially the reason he then dedicated himself to pacifist causes.]]
365* BadassBookworm: Not so much most of the time, but "Showdown, Part 1" demonstrates to us that he is one.
366* BigGood: He shares the position with Max and Paradox.
367* ComicBookFantasyCasting: In ''Alien Force'' and ''Ultimate Alien'', Creator/JeffBennett was channelling Creator/ReneAuberjonois--which probably explains why when ''Omniverse'' recast Azmuth, they just got Auberjonois himself to do the part.
368* CoolOldGuy: Zig-zagged; he is irascible, pessimistic, condescending, insufferable and brash, but on the other hand, he is well-intentioned and does display a softer side on occasions.
369* CrazyPrepared: He's called the "First Thinker" by the Galvans because he tries to prepare for every contingency he can think of. [[spoiler:For example, he built a device to disable the Omnitrix in case it ever fell into the wrong hands, which he uses on Albedo in Omniverse]].
370* CreateYourOwnVillain: A speciality of his; to date, he's responsible for turning the Incurseans into space pirates, giving [[spoiler:[[KnightTemplar Sir George]] [[InfinityPlusOneSword the Ascalon Sword]]]], and accidentally screwing up the body and mind of [[TheSociopath Malware]]. It's also implied that his dickery was what led Albedo to turn out the way he is.
371* CynicalMentor: Comes with being a cranky old man, even by Galvan standards. He can be wise in ways both worldly and emotionally, but at the end of the day, he's still a stressed-out old scientist.
372* DidntThinkThisThrough: For all of his genius, and usual good intention, the flaws with his Omnitrix are ''glaringly'' obvious, especially so in hindsight:
373** He created the Omnitrix in the first place to promote peace by making the "walking a mile in their shoes" a LiteralMetaphor, without taking into account all of the abilities the watch gives essentially making the user a OneManArmy and the various power-hungry villains who can steal it and use it for their own ends.
374** The Omnitrix's basic design is vague at best to beings that do not have space travel, or just don't understand technology in general, which considering the Omnitrix's purpose to promote relations between races is fairly unhelpful. No details explaining what the alien is or what its abilities are are elaborated, the most that a new user can get is a silhouette. This also extends to maintenance, since the Omnitrix can be surprisingly fragile in a few exploitable ways and can malfunction, there's also no immediately obvious way to fix it without going to someone privy to the technology.
375** He failed to take into account beings that can retain consciousness and reform FromASingleCell, which not only creates a possible AndIMustScream situation for that individual and the owner, but also leads to the creation of a villain in the form of Ghostfreak[=/=]Zs'Skayr.
376** Simply choosing an alien can be a chore due to the Omnitrix sometimes ''ignoring inputs'' for seemingly no clear reason. it also locks off its user from the majority of its functions, and will seemingly lock-off previous choices further down the line when new aliens can be accessed, also for no obvious reason. Omniverse later suggested that the reason the Omnitrix ignores inputs is that Ben keeps ''slamming'' the button down instead of just pressing it and it could be assumed that the locking off of old aliens was just a result of the Omnitrix being left idle for almost half a decade between the OS and Alien Force.
377* FigureItOutYourself: In his own words: "Don't you want to figure it out on your own, as a true hero would?" Humorously, he likes the fact that Ben was honest and told him he didn't want to. Still didn't help him learn.
378* ForScience: This used to be his primary motivation until it cost him his girlfriend and [[spoiler:he created a weapon that destroyed a planet]]; in the present his intentions are more altruistic, like creating the Omnitrix.
379* GoodIsNotNice: He is a well-intentioned scientist, a convinced pacifist and wants nothing but good for the universe. Sadly, he has the bad habit of acting like a dick with almost everyone around him.
380* GrumpyOldMan: ''Really'' gives off this vibe in the UAF era.
381* HeelRealization: He realizes it's just stupid to blow up the universe when the Omnitrix is near self-destruction.
382* IdiotBall: Azmuth isn't an idiot, but you still have to wonder what he was thinking when he came up with the "randomizer", a function that causes the Omnitrix to uncontrollably turn its owner into random aliens and basically serves no purpose other than make it even more difficult to use.
383* InsufferableGenius: He's never shy about bragging how he's the smartest being in five galaxies. Though he can back it up, much better than Albedo.
384* JerkWithAHeartOfGold: Azmuth can ''really'' be a dick sometimes and his social skills are abysmal, but he does mean well.
385* MadScientist: Sort of. He's currently more or less a reasonable scientist, but he still tends to be... eccentric, to say the least.
386* MyGodWhatHaveIDone: [[spoiler:His reaction when he found out what the Incursians did with the Ascalon sword.]]
387* NeverMyFault: In general, his AboveGoodAndEvil comes off as this to an incredibly unlikable degree. He blames the universe and its inhabitants for misuse of his creation(s), when put simply, he designed them and how they function in the first place without thinking of the consequences due to the raw power they could give. He does this to the point that he at first becomes a bitter reclusive hermit wasting time by waiting to die instead of trying to fix his mistakes and prevent suffering. Sequel series has the degree of this either turned down or up DependingOnTheWriter.
388* NoSocialSkills: That would almost be an understatement; Azmuth has a bad habit to act like an [[InsufferableGenius obnoxious]] [[JerkWithAHeartOfGold jackass]] with a lot of people around him, even though he almost always mean well; his first assistant ditched him for not, according to her, giving her any credit about the creation of the Omnitrix, his other assistant developed a massive superiority complex on him that led him to commit a FaceHeelTurn, his girlfriend left him because he was neglecting her for his work (and he ''didn't'' notice she had left until it was far too late) and one of his creation became a rampaging sociopath because he took his time to find a cure to heal him.
389* TheNthDoctor: While the ''Omniverse'' episode "Universe Vs. Tennyson" establishes Celestialsapiens, the source species of Alien X and a species of {{Reality Warper}}s, [[CosmicRetcon as the cause of the various redesigns]] and {{The Other Darrin}}s throughout [[Franchise/{{Ben 10}} the franchise]], Azmuth himself is cited as a specific example, pointing out his redesigns and voice changes (going from Creator/RobertDavidHall in ''Secret of the Omnitrix'' and ''Destroy All Aliens'' to Creator/JeffBennett doing a Creator/ReneAuberjonois impression in ''Alien Force'' and ''Ultimate Alien'', to Auberjonois himself voicing the role in ''Omniverse''.)
390* RestoredMyFaithInHumanity: Or the universe. By the time Ben met Azmuth in ''Secret of the Omnitrix'', the scientist had completely given up on the whole Universe, to the point that he was willing to let it, along with himself, be destroyed. However, after seeing Ben in action, he has a HeelRealization, helps Ben win, and becomes more rational in later episodes
391* SameCharacterButDifferent: He was a lot more sarcastic and cynical when we first see him in ''Secret of the Omnitrix'', but is more stoic and serious (though retaining a sense of sarcasm) by the time of ''Alien Force''. Justified in that there was a five-year TimeSkip in-between appearances.
392* ScienceHero: One of the most brilliant scientists in the Ben 10 universe, and he knows how to use his knowledge to his advantage.
393* SinkOrSwimMentor: With some very rare opportunities, such as the ''Alien Force'' season 2 finale, Azmuth usually prefers to let Ben figure out by himself how to use the Omnitrix, and very rarely helps him.
394* SmallParentHugeChild: Azmuth (a member of the Galvan species, who are small enough to stand atop a human's palm) is revealed to be the creator of the entire Galvanic Mechamorph race who are at least the size of humans, with the malevolent Mechamorph Malware who has a history with Azmuth outright referring to him as father at one point.
395* TheSpock: In the UAF era, he tends to encourage Ben toward no-nonsense choices. Less present in the Original Series and ''Omniverse''.
396* TechnicalPacifist: Azmuth dislike fighting and rarely takes part in conflicts directly, but will defend himself if it's actually needed.
397* TheWatcher: he can follow Ben's use of the Omnitrix on regular basis through elements inside the Omnitrix.
398* TookALevelInJerkass: He has always been kind of a dick, but ''Omniverse'' tends to exaggerate this aspect of his personality; In a flashback episode "Trouble Helix", he openly ''doesn't care'' when Max asks him for help about Ben being trapped in alien forms and refuses to help until Ben as [=XLR8=] starts wrecking his own lab. Also, he [[spoiler:takes petty revenge on Albedo for capturing him by casually trapping him in an 11 years old Ben form]].
399* UnwittingInstigatorOfDoom: His creation of Ascalon led to the destruction of the Incursean's homeworld, and giving it to George led to the foundation of the Forever Knights.
400* WorldsSmartestMan: Azmuth is considered the brightest mind in three to five ''galaxies ''and sometimes even the universe. He's a Galvan, a species already known for SuperIntelligence, and he's the brightest of them all, to where they named him First Thinker.

409One of the {{Bounty Hunter}}s recruited by Vilgax to get the Omnitrix in season 1 of the Original Series. It however later turns out he was actually TheMole and wanted to make sure Vilgax didn't get the Omnitrix. Tetrax actually is a Petrosapien who once accidentally allowed Vilgax to destroy his native planet of Petropia after providing him with the Crystal required to power his weapon. He has then been fighting Vilgax as a way to atone for his crime.
410----
411* TheAtoner: He attempts to prevent Vilgax from getting his hands on destructive devices as a way to atone for being the one who provided him with the crystal that allowed the destruction of Petropia.
412* BeardOfEvil: PlayedWith by his EvilDoppelganger of Dimension 23 in ''[[WesternAnimation/Ben10Omniverse Omniverse]]'', who has a fairly awesome-looking beard made of the same crystal the rest of his body is. However, the alternate Tetrax is more of a HeroAntagonist than a true villain.
413* BountyHunter: He's really good at hunting targets. He proved more or less an acceptable match to the combined forces of Sixsix and Kraab, and practically [[CurbStompBattle Curb Stomped]] Diamondhead during their first encounter
414* DarkIsNotEvil: Yes, the guy dressed in black armor with a helmet is a good guy.
415* GemstoneAssault: Well, he is from Diamondhead's species, so yeah. Notably, his suit apparently is built so he won't have to remove it to use his powers.
416* GoodAllAlong: In his debut, he's hired by Vilgax to retrieve the Omnitrix, but he reveals when he finally catches up to Ben that his actual mission is to retrieve the Omnitrix at all costs and keep it ''out'' of Vilgax's hands.
417* GoodCounterpart: To Sixsix in the original series.
418* HeelFaceTurn: Initially, he genuinely worked for Vilgax, but, he decided to fight against him after Tetrax became indirectly responsible for the destruction of Petropia by aiding Vilgax. By now, he still is a bounty hunter, but he only works for those he considers honest hirers. He seems to work on a regular basis for Azmuth.
419* HeroAntagonist: {{Downplayed}} by the prime dimension's Tetrax, who is revealed to be GoodAllAlong but is looking to remove the Omnitrix from Ben until the episode's end. PlayedStraight by the alternate Tetrax of Dimension 23: he and his allies are ultimately merely trying to retrieve Ben 23's Omnitrix and return it to Azmuth, with Ben 23's less-than-altruistic use of his Omnitrix up to that point and the seemingly widespread and indiscriminate distrust of aliens on that dimension's Earth seemingly leaving little room for argument.
420* HoverBoard: He has one, which he gave to Ben later. He was also introduced with this as his production name.
421* IdenticalStranger: To Diamondhead, especially since aliens of the same race can and often look different (except Highbreeds). Possibly justified considering he was supposedly the LastOfHisKind at this point, meaning his DNA was most likely used for Diamondhead.
422* ItsAllAboutMe: Used to follow this. It bites him in the arses ''hard'', and he gave up on it after that.
423* LastOfHisKind: By his own fault. [[spoiler:At least until Petropia is restored by Sugilite.]]
424* OOCIsSeriousBusiness: In the original series, he was pretty easygoing and a friendly ally. When he returns in ''Alien Force'', he immediately grabs Ben and starts screaming demands at him, as well as resorts to violence to get what he wants. It's because [[spoiler:he needs Chromastone to restore his people and there's only has so much time to pull it off, so politeness had to take a backseat]].
425* ReasonYouSuckSpeech: Delivers one to Ben at their first encounter, pointing out Ben's LeeroyJenkins tendencies and his lack of strategy. Fortunately, Ben was smart enough to learn from this.
426* TheReveal: He wore a helmet hiding his face for most of his first appearance; it wasn't until the last minutes of the episode that he removed it and revealed himself as a Pretrosapiens.
427* ThrowTheDogABone: [[spoiler:His planet gets rebuilt with all its population resurrected in "Secret of Chromastone" thanks to a combination of Chromastone's powers and a failsafe inside the crystal]].
428
429[[AC:Reboot]]
430* AdaptationalVillainy: Since [[spoiler:Vilgax didn't destroy his planet]] in this version, he is still an amoral bounty hunter.
431* BondBreaker: While calling him, Kraab and Sixsix TrueCompanions or even friends would be pushing it (as seen during their interaction in "Bounty Ball") it's implied they have worked together for quite some time and acted as a team on several missions. Due to Tetrax betraying the other two in "Mutiny for the Bounty", it's doubtful they'll work together ever again.
432* ChainedHeat: With Ben in " Mutiny for the Bounty ": it's a subversion, since it was Tetrax that chained them together to bring Ben to his client and could have released them anytime. The device holding them was also designed to counter Ben's transformations, like creating two more cuffs when he turned in Four Arms.
433* ExactWords: He captures Gwen and uses her as a hostage to force Ben to surrender, promising he will let her go if the child does. After Ben is captured, he drops her from the train roof they were fighting on.
434-->'''Ben:''' "You said you'd let her go!"
435-->'''Tetrax:''' "I ''did'' let her go."
436* KickTheDog: His ExactWords example above.
437* KnowWhenToFoldEm: After Vilgax gives him, Kraab and Sixsix a CurbStompBattle and sends them packing through their own teleporter, they wisely decide to not go back to the battlefield.
438* HealingFactor: Possibly averted: in "Mutiny for the Bounty" Kraab shatters one of his arms and he doesn't regrow it before leaving.
439* IOweYouMyLife: After Ben helped him fight Kraab and Sixsix (who Tetrax double-crossed to keep all the bounty to himself) he lets Ben go. He is quick to add that it's only for this time.
440* TheLeader: Of the group he forms with Kraab and Sixsix. After "Mutiny for the Bounty" it's safe to assume their group has been disbanded for good.
441* OnceASeason: Tetrax is a fairly recurring villain, having shown up once every season.
442* OnlyInItForTheMoney: Which makes him unpredictable: one episode he could be helping Ben fight Vilgax, in another trying to hunt the kid.
443* NothingPersonal: He said it verbatim to Ben in "Bounty Ball", explaining they were only hunting him for money. Ben (as Grey Matter) argued back that attacking his person is the definition of personal.
444* ScrewThisImOuttaHere: He and the other bounty hunters run away when Shock Rock proves too much for them.
445* SuperReflexes: Enough to keep up with [[SuperSpeed XLR8]], much to Ben's surprise.
446* TeleportGun: He uses it to quickly arrive and leave a scene.
447* VaguenessIsComing: When they give up on the hunt, he warns Ben it's only the beginning.
448--> "You're no longer worth the trouble anymore, flesh child! [...] We just wanted money! There will be others who want far more from you!"
449* WildCard: He has nothing personal against Ben, therefore it's impossible to guess if he will be on his side or not when they meet.
450* TheWorfEffect: He, SixSix and Kraab are quickly defeated by Vilgax, showing what kind of threat the conqueror is.

457
458The alien who was in charge of bringing the Omnitrix to Earth, and one of Max's old {{Love Interest}}s. She was the one who unlocked Upchuck for Ben.
459----
460* AcePilot: In "And Then There Were 10", she manages to shoot at [[BigBad Vilgax]] while he is still inside his ship, damaging him so much that he has to spend the whole season in a DarkLordOnLifeSupport situation.
461* ActionGirl: Xylene has impressive telekinetic powers which she uses expertly in battle. She is also the one responsible for injuring Vilgax in the first episode of the original series.
462* AmicableExes: She and Max ended their relationship on good terms.
463* BattleCouple: Xylene and Max were this during his days as a Plumber.
464* CallBack: She gets a mention in ''Omniverse'' episode "Gone Fishin'" as a ContinuityNod.
465* EmotionlessReptile: Her species, the Uxorites, while not absolutely emotionless, are very blunt and stoic in demeanor. She also mentions that Uroxites don't have much in the way of parental instincts, as newborns are left to fend for themselves after hatching, so she has problems understanding Max's continued attachment to his grandchildren Ben and Gwen.
466* GreenSkinnedSpaceBabe: Despite her tentacled features, she's a beautiful space babe.
467* LizardFolk: She is a reptilian alien.
468* LoveInterest: To Max Tennyson. Apparently, Max has a thing for alien chicks.
469* MaternallyChallenged: Xylene's species as a whole, since they don't take care of their offspring once they hatch. She isn't able to understand attachment to children in other species, which is implied to be a major factor in why her relationship with Max ended.
470* MindOverMatter: Xylene has the power of telekinesis. It's versatile enough to even control water.
471* NonMammalMammaries: An especially blatant case in that she explicitly states her species don't take care of their children at all, making you wonder the point of those.
472* TheNoseless: She doesn't appear to have any semblance of nostrils when shown at different angles. Which suggests tha Uxorites have different bodily means for acquiring oxygen.
473* SmallRoleBigImpact: She only appeared in two episodes, including one where we don't actually ''see'' her (only her ship is shown). Yet, she was the character who ''initiated the whole plot of the franchise''.
474* TechnicolorMagic: Her telekinesis surrounds anything it is used on in purple light.
475* ThirdEye: She has a third eye on her forehead.
476* WhatHappenedToTheMouse: She disappeared entirely after her ''one'' appearance (outside of a mention in ''Omniverse'') despite having a key role in Ben's origin, an obvious interest in Max, and a lack of explanation as to why Azmuth chose her to deliver the Omnitrix.

483Ben's first shown LoveInterest, and granddaughter of Wes Green, a retired Plumber and old friend of Max. She began to take an interest in Ben after he began transforming into Blitzwolfer, though only because she wanted to keep him as a pet. [[AllThereInTheManual According to a pop-up in the enhanced version original series episode ''Ken 10'', she is Ben's future wife and Ken's mother]].

487[[quoteright:290:https://static.tvtropes.org/pmwiki/pub/images/kai_os.png]]
488
489* DamselInDistress: Briefly at the beginning of Benwolf, where she gets caught in a flood and Ben has to save her.
490* FirstGirlWins: Subverted here but played straight later on. See below in the "Omniverse" section.
491* KickTheDog: In the Original Series, where she got interested in Ben only because she wanted to keep Blitzwolfer as a pet, something she flat-out admitted in his face with no remorse. Even ''Gwen'' was outraged by such an attitude. Instead of being a marker of being evil or mean, it's more a mark of being [[ObliviouslyEvil obliviously jerkish]]. She was too young and socially inexperienced to realize just how messed up it was, saying "I could train you, tame you...you know!" in such a way that she thought Ben, or anyone really, would be totally understanding of her mindset. At least she preceded it by saying Ben was still a nice guy and "the alien thing is cool"
492* LongHairIsFeminine: Her hair is long and straight in this series, and she's more feminine here than she is in "Omniverse", where she sports a ponytail.
493* LoveInterest: She was this for Ben, though it's mostly one-sided in the Original Series.
494* LovesMyAlterEgo: In her first appearance, she was more interested in Ben when he was Blitzwolfer.
495* [[NiceGuy Nice Girl]]: Moments of brushing off Ben's feelings and treating him like a pet aside, Kai is easily the most outwardly kind, most mild-mannered, and least sarcastic and snarky out of herself, Ben and Gwen in this series. She [[TookALevelInJerkass is far less so]] in the sequel series.
496* SmallRoleBigImpact: In the sense that she only had one appearance in the original series (minus a cameo in "Perfect Day") and then never appeared again until 3 sequels later. She then became Ben's most love interest and eventually his wife in the future. But had this episode not happened, then Kai wouldn't have existed and Ben may have ended up staying with or getting back together with Julie, or ending up with Esther (who in the game show episode, was made out to be his next most likely love interest at that point).
497* TomboyAndGirlyGirl: Kai is the girly girl to Gwen's tomboy in "Benwolf", with Kai's soft-spoken nature, mild manners and non-action traits clashing strongly with Gwen's snark, sass, brashness and temper.

502
503* AbsurdlySharpBlade: Excalibur is capable of cutting through blast-proof doors like they were butter.
504* AdventurerArchaeologist: She explores ancient ruins and other fantastic places alongside her grandfather in ''Omniverse.''
505* AscendedExtra: While Man of Action did confirm that she was Ben's wife in the future, she actually had a very little role in the Original Series, appearing only in ''Benwolf'' as a character and in "Perfect Day" as a cameo in Ben's dream while she was completely absent in ''Alien Force'' and ''Ultimate Alien''. ''Omniverse'' brings her back and makes her a recurring character as well as Ben's final LoveInterest and wife in the future.
506* BadassBookworm: Incredibly well versed in history and uses Big Ben's chimes as a distraction. Predicting just when they come.
507* BadassNormal: Uses martial arts and knowledge of alien technology to fight.
508* BelligerentSexualTension: She and Ben kind of have this dynamic in ''Omniverse'', spending almost all their time bickering to hide their real feelings. EveryoneCanSeeIt, and they don't hesitate to point it out every single time she appears.
509* BettyAndVeronica: She's the Veronica (a hotheaded {{Tsundere}} who constantly argues with Ben instead of admitting her feelings) to Ester's Betty (a friendly GirlNextDoor who makes her affection extremely obvious).
510* DeadpanSnarker: She has become this in ''Omniverse'', usually making dry remarks whenever Ben commits a blunder.
511* EveryoneCanSeeIt: The Forever Knights mistake them for boyfriend and girlfriend and Rook calls their back and forth arguing "romantic bantering".
512* FirstGirlWins: A double subversion: it isn't the case at first in "Benwolf", but ends up being played straight after all in "Ken 10" (which reveals that she is Ben's wife in the future). WordOfGod even confirms that she is the ultimate winner in Ben's ''Omniverse'' "harem." This comes to pass in "The Most Dangerous Game Show".
513* {{Flanderization}}: In the Original Series, her interest in Blitzwolfer was fairly subtle. She was interested in him in that she thought it could be amusing to have him as a pet, which was only expressed in one line at the end of the episode. When she comes back in ''Omniverse'', it has turned into a borderline obsession to the point of which that she encourages Ben to turn into him whenever the occasion presents itself and uses Blitzwolfer's picture instead of Ben's for his profile on her phone. "The Most Dangerous Game Show" pushes it even further by having her apparently love all of Ben's aliens but acting disdainfully of him when he is in human form to the point that she treats them as separate individuals.
514* FutureBadass: In the future, she has at some point found Excalibur and it is her main weapon.
515* HeIsNotMyBoyfriend: Says this about Ben in ''Omniverse.'' While it's true, there's clear romantic tension going on between them.
516* InformedAttribute: It's never actually explained ''why'' she's worthy of Excalibur, especially when Ben isn't. While he has his problems, he's shown time and again to be a noble hero at heart, while Kai comparatively has never displayed anything close to Ben's most self-sacrificial and altruistic moments.
517* LoveInterest: In ''Omniverse'', the two have BelligerentSexualTension in spades and hold each other's arms after Ben rescues her from falling off of Big Ben, though they break as soon as it's commented on. And she gives him a goodbye kiss on the cheek. "Secret of Dos Santos" is chock full of BelligerentSexualTension between the two, and she gives Ben (as [=XLR8=]) a kiss on the lips when he discovers the path to the temple.
518* LovesMyAlterEgo: She shows signs of this in ''Omniverse'', similar to the original series, wanting Ben to turn into Blitzwolfer, and petting him when he does and subsequently saves her from falling (though she does give Ben a parting kiss on the cheek).
519* OfficialCouple: As of "The Most Dangerous Game Show", though we never see her present-day self after this. She becomes Ben's girlfriend at the end of the episode and eventually his wife in the future.
520* SheIsAllGrownUp: Ben points this out as soon as he meets her again in ''Omniverse''. Then again, so's he.
521* TeethClenchedTeamwork: Once she and Ben meet again, this is the relationship they have. Even in the future where they are married with a son, they still bicker when fighting together.
522* TomboyAndGirlyGirl: She's the Tomboy (a tough, aggressive adventurer) to Ester's Girly-Girl (a flirtatious, romantic GirlNextDoor).
523* TomboynessUpgrade: Kai becomes less feminine here than she was in the original series, having taken several levels in [[TookALevelInBadass badass]] and [[TookALevelInSmartass smartass]], as well as adopting a TomboyishPonytail.
524* TookALevelInBadass: Between the original series and ''Omniverse'' thanks to after school judo lessons.
525* TookALevelInJerkass: Also in ''Omniverse''. Her KickTheDog moment in the original was [[ObliviouslyEvil done out of youthful obliviousness]], but now she knows exactly what she's doing when she's mean to Ben. To be fair, [[BelligerentSexualTension Ben often gives as good as he gets.]]

535
536Ben's future self. Since the future is constantly changing, and there are various timelines, we have seen different versions of Ben 10,000 over the course of the franchise, with at least two confirmed to be from different alternate futures (the third one is... [[ContinuitySnarl complicated]]).
537----
538* AlternateSelf: Presumably thanks to the future constantly changing, the Original Series, ''Ultimate Alien'', and ''Omniverse'' each gave a different version of Ben 10,000. While the one appearing in ''Ultimate Alien'' is confirmed both by WordOfGod and in-universe as being an alternate self, the two others' case is [[ContinuitySnarl somewhat less clear]] ([[WordOfGod Derrick Wyatt]] stated they are meant to be the same characters, but many elements between the two-- such as their relationship with Kevin-- don't match).
539* BroadStrokes: ''Omniverse'' Ben 10,000 is stated by WordOfGod to be the same one as in the Original Series, but many details about both of them (including WordOfGod from both previous and these same writers) don't match such as Kevin being reformed (or at least [[https://ask.fm/DerrickJWyatt/answers/120581521780 having a habit of switching regularly between villain and hero]]) and having lived the events of ''Alien Force'', ''Ultimate Alien'', and ''Omniverse'' (he was still evil and had spent his entire life in the Null Void in the Original Series). WordOfGod's explanation is that this was due to alteration in Ben's past- despite the existence of various alternate timelines being established. The Ben 10 Wiki notably disregards Wyatt's statements on this and presents the Omniverse Ben 10,000 future as just one possible future.
540* CompositeCharacter: ''Omniverse'''s Ben 10,000 has a slightly modified version of the original incarnation of Ben 10,000's design and life, but has some of the immature tendencies of his ''Ultimate Alien'' counterpart.
541* ContrastingReplacementCharacter: ''Ultimate Alien'' Ben 10,000 is seemingly designed to be the opposite of his original series counterpart. While the original spent all his time in alien form, Ultimate Ben spends all of his time in ''human'' form, able to use his powers without transforming. The original was a hyper-serious {{workaholic}} who had long lost the joy of being a hero, while Ultimate Ben is a {{Manchild}} who's remained just as cocky and lighthearted as his younger self.
542* FusionDance: In ''Omniverse'', his Biomnitrix allows him to transform into alien fusions, such as:
543** Atomic-X: Atomix + Alien X
544** Fourmungousaur: Four Arms + Humungousaur
545** Crashshocker: Crashhopper + Shocksquatch
546** Uprigg: Upgrade + Juryrigg
547** Big Chuck: Way Big + Upchuck
548** Humungoopsaur: Humungousaur + Goop
549* FutureBadass: Another thing all versions of Ben 10,000 have in common is that they are [[TookALevelInBadass several times more badass than Ben's present self]], usually having unlocked the Omnitrix's full potential and lost their immaturity with age. They all have access to 10,000 alien forms at the very least, can switch between forms with no glitches or time limit and fully know how to operate the Omnitrix even without the Master Control.
550* GadgeteerGenius: According to WordOfGod, he used the minds of his smartest aliens to create a second Omnitrix for his son, and did the same to create his Biomnitrix.
551* HappilyMarried: To Kai Green in the Original Series and ''Omniverse'', though in the former's case this is only known through [[AllThereInTheManual pop-up trivia]]. ''Ultimate Alien'' Ben 10,000's marital status was unknown.
552* InformedAbility: None of them ever get to use all 10,000 forms they are stated to have. Justified in that seeing 10,000 different aliens would require ''a lot'' of episodes.
553* {{Manchild}}: Compared to the other versions of him, ''Ultimate Alien'' {{retcon}}s Ben 10,000 into a not much more mature version of his present-day self. ''Omniverse'' Ben 10,000 kind of qualifies as well.
554* NoHoldsBarredBeatdown: When Kevin manages to knock out both Ken and Levin rather brutally, a waking Ben 10,000 goes from being unable to get a good hit on Kevin to being in such [[UnstoppableRage seething, teeth-gritting anger]] at the sight of [[PapaWolf his own son being injured]] that he immediately transforms into Way Big, and continuously slams on Kevin until he's a broken heap in a crater. [[HealingFactor Kevin gets back up]] and ''literally has to re-snap his bones into place'', but it helped set up a return to the Null Void.
555* NotSoAboveItAll: In his first appearance, he indulges the younger Ben's tendency to name his aliens when transformed into one the former doesn't know.
556-->'''Ben 10[=/=]Diamondhead:''' Hey, what do you call this guy?\
557'''Ben 10,000[=/=]???:''' I don't name... um, I don't know... "Absolute Zero"?\
558'''Ben 10[=/=]Diamondhead:''' Boooriiing. How about... "Articguana"?\
559'''Ben 10,000[=/=]Articguana:''' ...''cool''.
560* OneManArmy: Original Series Ben 10,000 was stated to have become so efficient he single-handedly patrolled the whole world to deal with criminals everywhere, making police and other superheroes obsolete.
561* OurPresidentsAreDifferent: President Action variety with ''Ultimate Alien'' Ben 10,000, who stated he was once President of Earth during a Vilgaxian invasion. Though he stepped down later to let Gwen take over.
562* PapaWolf: Towards his son, Ken. Deconstructed in ''Ken 10'', where he acts so protective toward Ken he doesn't actually leave him a chance to prove himself.
563* ParentsAsPeople: Though he means well, he's rather overprotective of Kenny and doesn't allow him many of the freedoms Ben had himself with the Omnitrix, such as giving him a rather unbalanced and mostly defensive set of aliens, and refusing to let him deal with any meaningful threat. [[ComicallyMissingThePoint He doesn't understand when Kenny inevitably gets frustrated with this.]]
564* SuperMode: ''Ultimate Alien'' Ben 10,000's "Ultimate Ben" form allowed him to use all his aliens' abilities without actually transforming into them.
565* TookALevelInJerkass: Original Series Ben 10,000, when met by his past self, had become cynical and quite anti-social, spending all his time in his alien forms and refusing any help. He gets better by the end of the episode.
566* TransformationNameAnnouncement: Both ''Ultimate Alien'' and ''Omniverse'' Ben 10,000 activate their unique abilities (respectively his Ultimate Ben alien powers and his fusion forms) by shouting the name of the forms.
567* VoluntaryShapeshifting: Unlike Ben's present self, Original Series Ben 10,000 has unlocked the Omnitrix' Master Control, allowing him to switch between all his form with no glitches, time limit or need to push the dial. Presumably, the other Ben 10,000 can do this as well.
568** ShapeshifterDefaultForm: In the original series, his most commonly used form was [=XLR8=], as it allows him to patrol the world much faster. Whenever he wasn't in a fight, [=XLR8=] was the form he was in.
569
570[[AC:Reboot]]
571* AdaptationalAngstUpgrade: Unlike the original Ben 10,000s, this version has [[AchillesInHisTent pulled out of active superheroics]] after an incident where his Grandpa Max died.
572* AdaptationPersonalityChange: This version of Ben 10,000 NeverGrewUp and is a ManChild living out of the dump with Hitch and a few dummies made out of trash.
573* AdaptationalWimp: Lacks the access to the Master Control his original counterparts had, and is thus just as prone to turning into the wrong alien as the 10-16year-old versions.
574* TheAllegedCar: His Omnitrix barely functions, and at one point leaves him [[BodyHorror stuck between human and Spidermonkey]].
575* BeardOfSorrow: His facial hair is reimagined as this, and [[spoiler:he shaves it off once he gets out of the funks]].
576* CompositeCharacter: Takes on a few traits of Alien Force-era Ben, such as the habit of drinking Mr. Smoothies, the ability to turn into Spidermonkey and [[spoiler:his look after cleaning himself up]].
577* HesBack: Resolving the invasion by the Xerge [[spoiler:leads Ben to clean himself up and get back into active heroism]].

582
583Ben 10,000's son. Was given a replica Omnitrix of his own on his tenth birthday. He is named after Gwen's older brother, Kenneth Tennyson.
584----
585* AllThereInTheManual: How there is even a second Omnitrix is explained in the pop-up edition of Ken 10: Ben 10,000 simply used his smartest aliens to create one.
586* ArtEvolution: In the original series, he had the skin tone of his mother, Kai. In ''Omniverse'', he had his father's skin tone in a brief cameo presented in "And Then There Was Ben". When he returns later in the episode "The End of an Era", he has Kai's skin tone again.
587* BroughtDownToNormal: He used to have an Omnitrix, but Ben and Kai took it from him when he was grounded. [[spoiler:Then he was given a time-travelling device by Paradox and became Spanner.]]
588* CallingTheOldManOut: He isn't pleased with his dad constantly babying him and calls him out on it.
589* TheCameo: He has a silent one in Omniverse.
590* DidYouJustPunchOutCthulhu: Helps bring down Kevin 11,000 with a set of defensive aliens and only a day's worth of experience.
591* {{Foil}}: While, as noted below, he acts a lot like his dad there are some key differences between Kenny and Ben: Kenny is far more tactical in his use of aliens than Ben was thanks to years watching his dad use them. He's also more appreciative of that kind of alien: his disappointment is more in not getting to pick his own aliens and the fact he has no offensive aliens than the aliens themselves (outside of Toepick), and he has a circle of friends, something 10-year-old Ben notably lacked.
592* GadgeteerGenius: He used Grey Matter to hack his Omnitrix, and unlock Master Control.
593* GenerationXerox: Acts just like dear old dad did at that age. His relationship with Devlin Levin also mirrors his dad's initial interactions with Devlin's dad Kevin.
594* TheGhost: Snakepit, Sandbox and Shellhead are the only aliens never seen on screen.
595%%* HotBlooded
596* IJustWantToBeSpecial: Really just wants to be a hero like his dad but Ben begins Kenny's career by protecting him at every turn rather than let Ken make his own mistakes.
597* InstantExpert: Is already fairly skilled with his aliens after less than a day of superheroing and with his father specifically trying to keep him out of harm's way. Justified as he seems to have a detailed knowledge of his dad's aliens.
598* JumpedAtTheCall: Had been chomping at the bit to join his dad in the hero business.
599* KidHero: Like father like son.
600* StoneWall: Shellhead, one of his unseen aliens who according to Ken his only power is being invincible.
601* StrongFamilyResemblance: To both his parents, having his father's looks but his mother's skin tone.
602* UnwittingPawn: Kevin Levin uses him to get to his dad.
603* WeakButSkilled: Ben put mostly defensive or skill-based aliens in his Omnitrix. He makes up for his skill and creativity with them. Becomes even more apparent when he uses grey matter to unlock master control.

609An alternate Ben introduced in "And Then There Were None", from a universe where there never was an Omnitrix.
610----
611* BadassNormal: Seems to be his future path, specifically [[spoiler:as a Plumber.]]
612* BeCarefulWhatYouWishFor: At the start of "And Then There Were None" he complains that nothing special ever happens and he wished for excitement, shortly afterwards he gets attacked by evil alternate Bens.
613* EstablishingCharacterMoment: Most of the first half of "And Then There Were None" highlights the similarities and differences between Prime!Ben and him: He is seen [[ChronicHeroSyndrome helping an old lady get her cat out of a tree]], [[IJustWantToBeSpecial finding the town he lives in boring, desiring more]], having an awkward relationship with his cousin (since without discovering the Omnitrix, they never became friends), and seems to have a friendly relationship with Cash and JT rather than the same one as Prime!Ben.
614* NaiveNewcomer: Spends the second act of "And Then There Were None" terrified and confused by the Omnitrix wielders until Paradox explains things.
615* NiceGuy: He is far less egotistical and self-centred than the regular Ben, presumably due to never becoming famous.
616* ScreamsLikeALittleGirl: When the regular Ben transforms into Spider Monkey, and when he's being carried away by him.
617* SmallTownBoredom: He's grown tired of living in Bellwood and desires to find something else in life.

620[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/ben_23.png]]
621->Voiced by Creator/TaraStrong
622
623An alternate version of Ben, whose own version of Grandpa Max died shortly before he received the Omnitrix and who thus had to teach himself how to use it. Though still ultimately fashioning himself as a hero, without Max's guidance and teachings this Ben became even more self-centred, amoral and obnoxious than our Ben had ever been, and knows next to nothing about the aliens he meets or turns into, or even about the Omnitrix itself. A worldwide figure, entertainment mogul and hero to millions, he lived a comfortable life milking his heroism for personal gain before an interdimensional meeting with Ben put him on the right track.
624----
625* AesopAmnesia: Downplayed. He tries to decline a plea for help to save the Multiverse from Vilgax and Evil Bens, still suffering a case of BystanderSyndrome, but goes along with them anyway since it's the right thing to do.
626* AntiHero: He's a fame-obsessed annoyance, but he does save the day in the end anyway.
627* AtrociousAlias: His alien names are, for lack of a better word, lame.
628* BystanderSyndrome: Surprisingly, considering Mainstream Ben's [[ChronicHeroSyndrome most defining trait of character]]. He doesn't lift a finger to help people being victimized by non-alien threats, because the press doesn't lap it up as they do when he fights titanic battles against aliens. Ben basically has to drag him into helping take down a bunch of bank robbers, and even so he takes so long trying to call his cameramen in to film the fight that he misses it entirely. What's worse, since the only villain he knows of is "The High Intellectual" ([[spoiler:actually Azmuth, trying to reclaim his Omnitrix]]), who specifically targets him, which means he only ever protects the public from threats that are only a threat to him in the first place.
629* CharacterCatchphrase: [[{{Pun}} "It's Gyro Time!"]] Also, calling his villains "haters."
630* FantasticRacism: Believes all aliens to be monsters, invaders or "[[TotallyRadical haters.]]" [[spoiler:He gets better.]]
631* FictionFiveHundred: He claims to be rich and influential enough to practically run Bellwood, which seems to behave weight in at least some respects.
632* {{Foil}}: He represents what Ben would've turned out to be without Max to rein in his ego and greed, and lacks the patience, skill, and some of the morals of the main Ben. [[CharacterDevelopment He gets better]], as a result of meeting the main version and working with Azmuth afterwards, though does still veer into his questionable morals.
633* GiverOfLameNames: Pretty much all of his aliens are poorly named, either as a line-of-sight on their appearance and powers or some variation of "[X] Guy/Man". Examples include Freezelizard (Articguana), Electricyeti (Shocksquatch), Charcoal Man (Heatblast), and Plug Man (Feedback). Though he changes Plug Man to Feedback after hearing Ben's name, and Eye Guy has the same name.
634* HiddenDepths: Ben 23 may well be a whiny, bratty, arrogant, selfish spoiled rotten twerp by nature; but he isn't completely without merits. At the end of "It's a Mad Ben World part 2" he gives a stunning speech of how individuals using the Omnitrix are only worthy of the power they wield when they use it to better the lives of others and he goes on to say [[ComesGreatResponsibility that with everything riding on their choices, they best not mess up]]
635* JerkWithAHeartOfGold: He's obnoxious and sometimes seems to care only about his fame and his image - even at the expense of other people at times - but deep down he really does want to be a hero, and he genuinely respects and looks up to our Ben after meeting him. He is also legitimately receptive to Ben's advice, even when it goes against what he's built his image up to be [[spoiler:though he doesn't really let it sink in until after he nearly kills Azmuth and Ben has to get tough with him]]. By the end, he comes off more as a misguided kid than the all-out jerk he seems to be.
636* LonelyAtTheTop: Pointed out by [[spoiler:his version of Azmuth]] when the two finally meet: Ben 23 has money, fame and the adoration of millions, but none of that holds a candle to having Grandpa Max with him - and he still misses him.
637* MilesGloriosus: Exhibits many traits of this, though he is not a complete example. Though he is a competent and effective hero in his own right, he constantly exaggerates or even lies to make himself look better, particularly in front of his less accomplished but far more heroic alternate version.
638* MoralityPet: Ben Prime tends to act a lot more mature whenever he's around Ben 23, steering him away from selfish decisions and toward a genuine heroic path.
639* [[ObliviouslyEvil Obliviously Amoral]]: Though he certainly wasn't above using the idea to make himself look good, he legitimately had no idea that not all aliens were evil. When Ben tells him so, he's amazed rather than disbelieving. After learning his lesson, he gradually becomes a much better person for it.
640* OffscreenMomentOfAwesome: He has Nanomech, or "Teeny-Weeny" as he calls him, meaning that at some point, he fought and defeated his world's equivalent to the Nanite Hive. [[note]]WordOfGod says that Nanochips in Dimension 23 are actually a sapient species known as a Nanomites, so it might not necessarily mean Ben 23 fought them.[[/note]]
641* PaletteSwap: His Omnitrix is a blue and gold version of Kid Ben's, and his aliens are blue palette swaps of Ben's.
642* [[PersonAsVerb Person As Adjective]]: He tends to use his own name as slang for "awesome," as in "that was so totally Ben." Given that he uses it when hyping up a crowd, it's likely part of his image.
643* StepfordSmiler: He seems cocky and content with the rich lifestyle he's built for himself, but it's really just a cover to cope over the loss of Grandpa Max.
644* TrademarkFavoriteFood: Gyros - literally, as his name is branded all over his favorite franchise. Though when asked about it he dismissively refers to Gyros as "yokel food," possibly implying that his love for them may be just another part of his image.
645* UnskilledButStrong: Self taught with the Omnitrix, and as such lacks finesse in the way he uses his aliens - in favor of brute force. Unlike the main Ben, though, he can at least consistently pick the transformation he actually wants.
646* VagueAge: It's never stated exactly how old he is, but he appears to be older than Ben's kid self, but younger than his teenage self, meaning he's somewhere between 11 and 16. WordOfGod says he's 12-14.
647
648!Gwen 10
649[[quoteright:100:https://static.tvtropes.org/pmwiki/pub/images/gwen_10.png]]
650->'''Voiced by:''' Creator/AshleyJohnson
651
652A Gwen Tennyson from an alternate timeline where she got the Omnitrix instead of Ben.
653----
654* AscendedExtra: Amusingly enough, she wasn't even technically a character at first; "Gwen 10" was a WhatIf episode from the Original Series imagining how things would have gone if Gwen got the Omnitrix instead of Ben. In fact, Gwen didn't even get to keep the Omnitrix at the end of this episode. Comes ''Omniverse'', the concept is used to create an alternate timeline where she actually kept the Omnitrix.
655* DistaffCounterpart: Her alien forms are all female versions of Ben's.
656* InstantExpert: No Watch Ben and Paradox pick her up on the same night as the Omnitrix arrived, yet she demonstrates nearly the same level of skill with her aliens as the others do theirs.
657* LittleMissBadass: Still 10 years old when she appears, and still kicks ass.
658* PaletteSwap: Her Omnitrix is the original, but with the same colors as her shirt, the symbol has cat ears like on her shirt, and the green has been changed to [[PinkMeansFeminine pink]].
659* TookALevelInKindness: It might just be because of the situation, but compared to mainstream 10-year-old Gwen, she is a lot less abrasive toward the various Ben she teams up with, and while she still snarks at them, it's much less mean-spirited.
660
661!Argit 10
662[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/argit_with_trix.png]]
663->'''Voiced by:''' N/A
664
665An alternate Argit briefly seen when Paradox is recruiting the alternate Ben's. In his reality, he got the Omnitrix. Not much about him is known other than that his Omnitrix is gold and he's filthy rich.
666----
667* BlingBlingBang: His Omnitrix is golden.
668* TheCameo: Only appears as a gag and is never actually interacted with.
669* JokeCharacter: The protagonists are so repulsed by this version of Argit that they simply refuse to recruit him even though having an extra Omnitrix wielder would help them in their plans against Vilgax and Eon.
670* NoJustNoReaction: The Bens, Gwen and Paradox quickly back out of his reality. This includes No-Watch Ben and Gwen, neither of whom had ever met Argit.
671* NoodleIncident: Apparently, his universe's version of Azmuth was so saddled by gambling debts that Malware was content with leaving him be and watching him struggle, so he sold the Omnitrix to Argit to cover some of them.
672* PooledFunds: Swims in a pile of money [[WesternAnimation/DuckTales1987 Scrooge McDuck]]-style.

676[[quoteright:277:https://static.tvtropes.org/pmwiki/pub/images/devlin_levin_0.png]]
677->'''Voiced by:''' Creator/CharlieSchlatter
678
679The son of Kevin 11,000 from an Alternative Timeline.
680----
681* AllThereInTheManual: Pop-up trivia states that Devlin did not inherit Kevin's absorption abilities, just his Omnitrix amalgam form.
682* EveryoneHasStandards: Although it was the Tennysons who locked his father away Devlin tried to keep his father from hurting them since he didn't want to hurt anyone and only wanted a family.
683* FreudianExcuse: He tricked Kenny into thinking they were friends in order to get access to the Null Void projector and release his father, a very dangerous criminal although he only did that because he loved his father and wanted him in his life. [[spoiler: The altered version of the timeline shown in ''Omniverse'' makes this considerably softer as that version of Kevin 11,000 had simply been driven insane by absorbing extreme amounts of energy and was eventually cured, returning him to a state more consistent with his CharacterDevelopment.]]
684* HappilyAdopted: He was thrilled when Ben and Max offered to adopt him.
685* HeelFaceTurn: When he realized that Kevin didn't care about him and only wanted revenge on the Tennyson family Devlin quickly turned on him, apologized to Kenny and helped the Tennysons re-capture him.
686* MissingMom: Devlin's mother is never seen nor mentioned. It was revealed in pop-up trivia that his mother was a woman from a Saturn colony whom Kevin had a relationship with before being captured and thrown back in the Null Void. It is never revealed what happened to her.
687* RaisedByRival: Ben decides to adopt him after re-capturing Kevin 11,000 since Devlin has no mother and Kevin couldn't care less about him.
688* RhymingNames: Devlin's name is just two letters away from his surname Levin.
689* StrongFamilyResemblance: He looks a lot like his father when he was a child.

693!Galactic Enforcers
694[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/future_galactic_enforcers_003.png]]
695
696A trio of alien superheroes introduced in the Original Series, first met by Ben when they came on Earth to track Sixsix and Vulkanus. Their group consisted in [[TheLeader Ultimos]], a {{Superman Substitute}}; [[TheBigGuy Tini]], a female Tetramand; and [[TheSmartGuy Synaptak]], an brain-like alien with psychic powers.
697----
698* AbhorrentAdmirer: In her introduction, Tini had a crush on Fourarms, much to Ben's dismay. This ends after he arranged for Synaptak and her to get together.
699* AmazonChaser: Synaptak has feelings for Tini, a ''[[ProudWarriorRaceGuy Tetramand]]'' girl.
700* ByTheBookCop: Ultimos bases his behaviour entirely on the Galactic Code of Conduct.
701* [[DroppedABridgeOnHim Dropped A Bridge on Them]]: While it's left ambiguous whether they actually died or not, all three of them are defeated by Vilgax in ''Vengeance of Vilgax'', with Tini and Synaptak disappearing under a rock slide and Ultimos having his powers absorbed by the warlord. They haven't been seen since then.
702* FlyingBrick: Ultimos, being based on Superman, shares the same powers.
703* HeadBlast: Synaptak can fire beams of telekinetic energy from his brain-like head.
704* InsufferableGenius: Synaptak acted this way toward Ben, though it's unclear whether it really is his usual personality or if he was just jealous about Ben getting Tini's attention.
705* MindOverMatter: Synaptak's power.
706* OfficialCouple: Synaptak and Tini, thanks to Ben.
707* OvershadowedByAwesome: In the Original Series' future, Ben 10,000 became so effective of his own he basically made the three of them obsolete, reducing them to glorified cops who come to arrest the criminals after he defeated them. However, after being enlightened by his 10-years-old self, he decides to let them handle some criminals again.
708* {{Pastiche}}: Ultimos is one of Superman.
709* SupermanSubstitute: Ultimos is a FlyingBrick alien with a KryptoniteFactor and a friendly demeanour.
710* WeaksauceWeakness: Ultimos is vulnerable to chocolate.
711* TheWorfEffect: Ultimos gets [[CurbStompBattle easily defeated and depowered]] by Vilgax as a way to re-establish him as a big threat.

718[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/tiffany_1.png]]
719
720Tiffany is a student at Bankcroft Academy. She is known to have a stuck up attitude, and disliked the Tennyson family because they're middle-class.
721----
722* AcademicAlphaBitch: In spite of her AlphaBitch tendencies as described below, Tiffany is ultimately successful at academics, given how she is a student of a prestigious school. Not that this is shown. See InformedAttribute.
723* AlphaBitch: She welcomes all potential new students to the academy and seems to have a high influence over the decision of whether or not they get accepted. Anyone who doesn't meet her standards of class and social status gets rejected. Because of her prejudice of the Tennyson family, Gwen doesn't get in.
724* BitchInSheepsClothing: She tries to put on a polite and friendly, welcoming facade when introducing potential new students to the school. She's actually snobbish, condescending and unwelcoming.
725* DamselInDistress: She ends up being held hostage by the Circus Freaks and the titular ghost in "Ghostfreaked Out".
726* InformedAttribute: Given she is a student at the highly regarded Bankcroft, she is allegedly a really smart and talented person. However, all we see of her is her acting like a stuck-up snob and nothing else. She's utterly useless in the climax of the Tennyson's versus Ghostfreak and the Circus Freaks. Ben quickly points this out when praising Gwen, someone with actual ActionGirl capabilities who contributed to stopping the villains.
727%%* LongHairIsFeminine
728* ThePerfectionist: In the sense that every student at the academy has to maintain the standards she has in mind of perfect class, refinery and decorum. People from "quality families" just don't make the cut for her.
729* RealWomenDontWearDresses: Tiffany wears a skirt and has a generally more feminine appearance than Gwen. Guess which of the two girls is actually [[ActionGirl useful]] when the school is attacked and the heroes and villains face off?
730* SlobsVersusSnobs: Tiffany is high class and a student of the prestigious Bankcroft Academy. She denies Gwen the right to enrol there because she is from a "quality family".
731* TomboyAndGirlyGirl: Tiffany is the girly girl to Gwen's tomboy. The former is a snobbish, stuck-up, high class AlphaBitch, compared with the snarky and brash, action-prone latter.
732* UngratefulBastard: Ben saves her life when she's in peril and she shows no gratitude for this at all.

738->Voiced by Creator/VanessaMarshall (''Secret of the Omnitrix''), Vyvam Pham (''Alien Force'')
739
740A female Chimera Sui Generis (Vilgax's species) who worked as Azmuth's assistant and helped him developing the Omnitrix. He refused to give her credit for it though, resulting in her taking her revenge by putting her own signature inside it instead of Azmuth's. During ''Secret of the Omnitrix'', she is found in Incarcecon by Ben, Gwen and Tetrax, and helps them find Azmuth. After the universe has been saved, she makes up with Azmuth and become his assistant again.
741----
742%% Doesn't explain what the reation is. * BerserkButton: She takes offense to being mistaken for Vilgax (plus she's a woman, so...)
743* TheCameo: Briefly appears in "The Most Dangerous Game Show".
744* {{Cthulhumanoid}}: Just look at her. Though she won't drive you insane or anything like that.
745* GeniusBruiser: she is a brillant enough scientist to be Azmuth's assistant; she also is from the same species than Vilgax.
746* LovableCoward: More than willing to let a ten-year-old do the fighting.
747* MySpeciesDothProtestTooMuch: Chimera Sui Generis are supposed to be an aggressive, warrior species (proven in the ''Omniverse episode'' "Vilgax Must Croak"; they managed to repel a full-scale invasion of their homeworld by [[TheEmpire the Incurseans]] in a matter of hours). Myaxx, on the other hand, is a self-admitted coward who rather avoids fighting whenever possible.
748* ProgressivelyPrettier: When she was first introduced in ''Secret of the Omnitrix'', she barely had any difference with Vilgax's original appearance to the point Ben actually mistook her for him. Her cameos in ''Alien Force'' and ''Omniverse'' gradually despict her as [[http://images4.wikia.nocookie.net/__cb20100709151821/ben10/images/c/ce/Myaxx_AF.png more feminine]] [[http://vignette2.wikia.nocookie.net/ben10/images/d/d4/Myaxx_ov.png/revision/latest?cb=20141113061359&path-prefix=es and attractive]]. A strange choice when you consider her initial appearance was very explicit about her looking like Vilgax.
749* UnwittingPawn: WordOfGod revealed that she was the one who accepted [[EvilOverlord Zs'Kayr]]'s offer to provide her with DNA samples for the Omnitrix, allowing him to secretly put his own sample amongst them and resulting in [[EnemyWithout Ghostfreak]].

759-> Voiced by Creator/DavidMcCallum
760
761An unknown scientist from the UsefulNotes/ColdWar who was experimenting on TimeTravel. His experiment went wrong, causing him to end up floating randomly through space and time for 100,000 years, unable to die or age. Though initially becoming insane because of it, he eventually became BoredWithInsanity, and was able to take control over his time travel, starting to use it to [[SetRightWhatOnceWentWrong save Earth at various points by alternating the course of time]]. This led him to meet with Ben's team during the UAF era. Though [[EccentricMentor eccentric]], he is otherwise a reliable ally.
762----
763* TheAgeless: Due to existing outside of time, he can't age and apparently also doesn't need to eat or sleep. This also makes him immune to time manipulation to some degree (he can't be aged into dust or anything like that, but he still feels it to some degree).
764* AllPowerfulBystander: While he does assist the heroes from time-to-time, he's prevented from being there for every instance. It's later explained that being a ParadoxPerson whenever he visits a location, the walls of reality will thin and eventually threaten it's destruction. This may also be in part due to the fact if he always stayed, he would be a case of StoryBreakerPower.
765* ArtificialLimbs: [[spoiler:In ''Omniverse'', he apparently lost his hand in the Time War and has replaced it with the Chrono Navigator disguised as a bionic hand.]]
766* BadassBoast: Tells Eon that if he goes through with his plan, no force in all of time will be able to protect him from Paradox.
767* BadassBookworm: Well, he used to be a scientist after all and since his field was studying and manipulating time... Well, he's better at that now.
768* BadassInANiceSuit: Nice tie.
769* BigGood: One of the most powerful forces of good in the franchise, whose purpose is to counter any evil that threatens all of space-time.
770* BoredWithInsanity: In his own words:
771-->''"At first, [[GoMadFromTheIsolation I went mad, of course]]. But after a few millennia, I got bored with that, too, and went sane. ''Very'' sane."''
772* CallForward: WordOfGod said that in ''Race Against Time'' (a movie that's otherwise non-canon), Paradox guarded the Hands of Armageddon from Eon for several years until Ben stopped him.
773** This is finally revealed in "Ben 10,000 Returns". [[spoiler:The movie was actually set in an alternate timeline and thus Paradox guarded that alternate timeline's Hands of Armageddon.]]
774* TheCameo: He makes a brief one in "Blukic and Driba Go to Area 51". Prior to becoming immortal, he worked at Area 51 with Max and Colonel Rozum.
775* CloudcuckooLander: His constant time travel and immortality cause him to often appear as this; he doesn't live events in the right order (for example, he apparently met a future version of Ben ''before'' meeting present Ben for the first time) and will offer gumballs to people in inappropriate situations.
776* CoolOldGuy: He doesn't look like it, but he is really 10,000+ years old.
777* CulturedBadass: He dresses and speaks the part of a well-educated ScienceHero.
778* DoctorWhomage: Paradox is basically a giant love letter to the [[Characters/DoctorWhoDoctors Doctor]], especially [[Characters/DoctorWhoTenthDoctor the tenth incarnation]] played by Creator/DavidTennant.
779** The quirk of offering gumballs brings to mind Creator/TomBaker's [[Characters/DoctorWhoFourthDoctor Fourth Doctor]] (with him offering jelly babies).
780** His Chrono Navigator has taken the shape of a pocket watch, referencing the fob watch that is part of the TARDIS chameleon arch. It also took the form of a gauntlet, which references Rassilon's gauntlet from [[Recap/DoctorWhoS30E17E18TheEndOfTime "The End of Time"]].
781** He has a tendency to use the phrase "Spoilers", taking after [[Characters/DoctorWhoRiverSong River Song]], a companion of the [[Characters/DoctorWhoEleventhDoctor Eleventh]] and [[Characters/DoctorWhoTwelfthDoctor Twelfth Doctors]].
782** He DoesntLikeGuns, similar to most incarnations.
783** Both have had [[AnArmAndALeg their arm cut off]], with the Tenth Doctor losing his arm shortly after his regeneration before it grew back, while Paradox lost it offscreen and replaced it with his Chrono Navigator.
784** He once utters the Fourth Doctor's line: "[[Recap/DoctorWhoS13E3PyramidsOfMars I walk in eternity.]]"
785** [[Characters/DoctorWhoWarDoctor Both]] have participated in a Time War.
786* DoesNotLikeGuns: When first meeting Colonel Rozum, he removes his gun from him without him noticing and throws it away, saying he never liked them.
787* TheFogOfAges: He calls himself "Paradox" because he can't remember what his real name is (despite the fact [[spoiler:he meets an old colleague who does]]).
788* FourthWallObserver: Overlapping with LeaningOnTheFourthWall, Paradox appears to be aware of when the commercials are going to come on.
789* GoMadFromTheIsolation: He spent nearly ''ten thousand years'' floating randomly through time, but eventually, he got BoredWithInsanity and went sane again. ''Very sane.''
790* TheHerald: He will pop out of a time portal near Ben and say, "I need your help with X".
791* HaveWeMetYet: Asked Ben this when they (from Ben's perspective) met for the first time. From Paradox's perspective at this point, they're already old friends.
792* HeroOfAnotherStory: He is constantly on adventures of his own and the first time he appears, it's stated he's already saved the world ''hundreds'' of times.
793* LabcoatOfScienceAndMedicine: His original attire has him wearing a lab coat, before he changes to a steampunk outfit.
794* LivingForeverIsAwesome: Not at first, but learned to accept it and presently he thinks eternity is glorious.
795* MysteriousPast: A past even ''he'' barely remembers due to TheFogOfAges.
796* OffscreenTeleportation: He has this ability due to 'finding shortcuts' in time. Though he's also very capable of onscreen teleportation.
797* OnlyKnownByTheirNickname: Everyone calls him Paradox, even himself. He says he has forgotten his name after the many millennia he has lived, though his former lab assistant appears to be the only one left knowing.
798* OtherMeAnnoysMe: Subverted, as when they meet the parallel Paradox he warns his counterpart not to follow the same course of his actions.
799* PersonaNonGrata: He is banned from interacting with Alien X (or any Celestialsapien, for that matter), [[NoodleIncident for reasons unknown]].
800** May have something to do with hiding the Forge of Creation, which is a NoodleIncident in itself.
801* RedBaron: "Timewalker".
802* ReallySevenHundredYearsOld: He looks middle-aged, but is the oldest ''thing'' in the series, other than the universe itself. [[spoiler:Considering the current universe is an Alien-X made reboot, he may have graduated to oldest thing ''period''.]]
803* SetRightWhatOnceWentWrong: His job for the past several hundred years.
804* SinkOrSwimMentor: In the sense that he can't outright interfere, but he does provide hints and warnings that help guide Ben and the others' actions.
805%%* StealthMentor:
806* StoryBreakerPower: If he were to remain with Ben's Team all the time, he would thwart most of the threats with ease, but he's forced to play AllPowerfulBystander except in the most dire of times. The thing is, he ''could'', remain with them, but there is just so much risk involved.
807* SuperSpeed: As an extension of his TimeMaster powers, he can slow down time around him, making it seem as though he's traveling at high speed.
808%%* TemporalParadox: Once a theory of his, now the frequent result of his actions.
809* TimeAbyss: Originally from TheFifties, he was sent back to the beginning of time and went on from there.
810* TimeDissonance: He can displace his time and location at will and he doesn't need to eat or sleep. He never ages.
811* TimeMaster: There is little he can't do to manipulate time.
812* TimePolice: Self-appointed guardian of time.
813* TimeTravelTenseTrouble: For instance, "You're much smarter than you were when I met you later."
814* TimeyWimeyBall: Several time travel theories can be drawn from him depending on the episode.
815%%* TricksterMentor: Another technique he uses.
816* TookALevelInBadass: In ''Omniverse'', he gets to engage in fights and seems to be good at it. He even effortlessly defeated two of Eon's {{Mooks}} by himself!
817* WillNotTellALie: It's not made clear whether he's actually incapable of lying or if he chooses not to, but even Eon knew Paradox well enough to know that he never lied.
818* YouCantFightFate: Played with; he himself constantly changes the timeline to save the world, but much like [[Series/DoctorWho the character he is based on]], he seems to follow the idea that there are some events that cannot, or in some cases, ''should not'' be changed. Most notably, he advises Gwen against trying to prevent Kevin's mutation in season 3 of Alien Force.

822!Anodites
823Introduced in ''Alien Force'', Anodites are a species of [[EnergyBeing incoporeal aliens made]] of {{Mana}}, the LifeEnergy at the source of magic. This grants them unusually powerful magic abilities, which can sometimes be inherited by their posterity.
824----
825!!'''Tropes applying to the species as a whole''':
826* EnergyBeing: Composed of what is essentially magic energy.
827* AFormYouAreComfortableWith: While their true forms are vaguely humanoid {{Energy Being}}s, they can use their powers to create themselves a physical body and appear as humans, allowing them to mate with them as a result.
828* BarbieDollAnatomy: Anodites don't appear to wear any clothing in their true forms, but the parts of their body that would show genitalia are devoid of it.
829* DittoAliens: The only three Anodites we see (Verdona, Gwen and Sunny) all reuse the exact same model. It's particularly noticable with Verdona, given that she's much older than her grandchildren, and still looks relatively young in her Anodite form.
830* GlowingEyesOfDoom: Their eyes tend to gow when they're casting spells.
831* GoodSamaritan: According to Verdona, Anodites often use their powers to help people across the universe despite their flighty hedonistic ways.
832* LadyLand: It's implied there are male Anodites, but only females have been shown so far.
833* MageSpecies: By virtue of being ''made'' of magic energy to begin with, they all naturally have magic powers. While this ability, which they refer to as the "Spark", isn't always passed to their posterity, it does sometimes happen, resulting in half-Anodites with impressive affinity for magic and who can eventually become Anodites themselves.
834* MagicIsFeminine: The only Anodites seen in the series are female.
835* {{Mana}}: They are ''made'' of that stuff.
836* MonochromaticEyes: White.
837* OneGenderRace: Implied. We don't ever see any male Anodites, and Ben, Frank and Carl Tennyson didn't inherit the Anodite genes like Gwen.
838* OutOfFocus: They aren't ever brought up in ''Omniverse'', despite ''Alien Force'' and ''Ultimate Alien'' showing they're a big deal to Gwen's lineage, and all Verdona got was a planned cameo which was eventually cut because of time constraints. Part of this is most likely because Derrick J. Wyatt has more than once said he didn't care for them.
839* PurpleIsPowerful: Their bodies are purple and their "hair" is pinkish purple.
840* RealityWarper: Not to the extent of Celestialsapiens, but their magic does allow them to warp reality to an extent. Ironically, their natural prociency with mana is one of the celestialsapiens few official limits.

846
847Max's wife, as well as Ben's and Gwen's paternal grandmother. Verdona's an Anodite, from a species of alien, {{Mana}}-controlling {{Energy Being}}s. She is the one Gwen got her affinity with magic from.
848----
849* BadassInDistress: In her backstory, she was this when she met Max for the first time.
850* BlueAndOrangeMorality: She left her family when she found out none of her direct children had inherited Anodite powers, treated Gwen favorably over Ben because Ben was lacking said powers (though in her defense, she got better on this side), and attempted to ''destroy'' Gwen's body to turn her into an Anodite against her will (again, they managed to talk her out of it). She seems to see ''nothing'' wrong with all of this and regards attacking her own grandchildren as a fun game.
851** On the other hand, destroying Gwen's body is more or less just peeling a full-body mask off her (which is implied they can put back on) and she does make sure to fix all the damage their scuffle caused before leaving.
852* ChuckCunninghamSyndrome: She does not appear in ''Omniverse''. Justified due to downplaying Gwen's anodite heritage and Gwen's already severely reduced screen-time.
853** She was originally going to make an appearance in ''Omniverse'' episode “The Most Dangerous Game Show” (the designers of the show were even finished with her new design), but she was cut.
854* EveryoneHasStandards: Though Sunny Tennyson embraces her Anodite heritage and magical abilities like Verdona wanted Gwen to do, she actively looks down on her other grandchild because she's so unpleasant and bratty.
855* {{Irony}}: Despite her dismissive attitude towards humans and hedonistic nature, the straight-laced half-Anodite Gwen who embraces her humanity over her Anodite heritage is her favorite grandchild. The full-blooded Anodite granchild and Gwen's polar opposite, Sunny, who embraces her Anodite heritage is Verdona's least favorite grandchild despite supposedly embracing everything Gwen refuses because she's also a SpoiledBrat.
856* ItsAllAboutMe: Despite her good intentions, she's very selfish when it comes to her desires and prides herself on doing whatever she pleases.
857* IWasQuiteALooker: Her Anodite appearance hasn't changed, but her former [[https://vignette.wikia.nocookie.net/ben10/images/9/9f/Verdona_young_human_form_full_body_UA.png/revision/latest/scale-to-width-down/85?cb=20190228033423 human disguise]] was something to see. Even in her aged human form, her daughter-in-law can't help but admit she's still attractive.
858* TheMourningAfter: Though she tries to play it down when the subject is brought up, it's clear that Verdona was devastated at the news Max had passed away (he didn't but she didn't know that), returning to Earth and leaving behind flowers made of her own mana at the [[SweetieGraffiti tree that bore their names]].
859* NeverMessWithGranny: Literally; she is an actual grandmother, yet was able to handle both Ben, Kevin and later Gwen in a fight at the same time. She's also clearly much stronger than her other granddaughter, Sunny, who, unlike Gwen, is a full-blooded Anodite.
860* NinjaPirateRobotZombie: She is an alien EnergyBeing with magic-based powers.
861* ParentalAbandonment: She outright abandoned her human family when none of them showed hints of having Anodite powers, only returning when she heard Max had passed away and discovering by chance that Gwen had them and wanted to make her embrace her Anodite heritage. To give her some credit, she only left Earth after her children had grown up and left to pursue their own lives.
862* ParentalFavoritism: Grandparental Favoritism in this case. In ''Ultimate Alien'' she admits that Gwen is her favorite grandchild much to Sunny's dismay. Verdona also doesn't mind Ben and appears to be impressed by his battle prowess, but she's also disappointed with his lack of Anodite abilities.
863* RescueRomance: She was captured by someone who wanted to use her for her energy powers and she was rescued by Max, hence how their relationship started.
864* SecretSecretKeeper: Max never told her about his work with the Plumbers, but Verdona found out regardless. Given how famous he was among the alien community, it probably wasn't that hard either.
865* SitcomArchNemesis: Gwen's mother, Natalie, and Verdona don't seem to get along that well.
866* TimeDissonance: When Gwen's father comments on how long it's been since they last met, Verdona concedes it probably was... in human time at least.
867* TookALevelInKindness: While not a bad person, it is noted she is somewhat detached from her human side in her debut episode. She is more amicable and friendly the next time we see her.
868* VirtuousCharacterCopy: WordOfGod is that she was inspired by Endora from Series/{{Bewitched}}. But unlike her inspiration, who was a cantankerous ObnoxiousInLaws who resented her daughter wanting to be normal, Verdona is shown to appreciate her non-magical relatives, even if not to the same extent as Gwen.

873
874Verdona's other granddaughter and a cousin of Ben and Gwen's who, unlike Gwen, is a full-blooded Anodite. Sunny's human disguise is pretty much identical to Gwen's appearance, except for having black hair (while Gwen's a redhead) and blue/purple eyes (while Gwen has green eyes).
875----
876* AlwaysSomeoneBetter: Gwen's apparently this to her--Sunny finds this especially annoying because, despite not being a full-blooded Anodite and her lack of formal training, she's still very skilled and her powers/abilities are developing quite nicely. Sunny also appears to be jealous of the fact that Verdona considers Gwen to be her "favorite" grandchild. It's enough to earn her [[JerkassWoobie some sympathy]].
877* BlondeBrunetteRedhead: For the most prominent female Tennyson-related cousins, she's the brunette, while Lucy's the blonde and Gwen's the redhead.
878* EatingTheEyeCandy: She tries to hit on Kevin and calls him "Muscles".
879* FreudianExcuse: It's implied that her troublemaking ways were rooted by the fact that her grandmother Verdona favors her cousin Gwen over herself.
880* GracefulLadiesLikePurple: Inverted, in the sense that she isn't as well-mannered as her cousin Gwen is.
881* IronicName: Despite how much she can express joy, her own name is actually pretty contradictory to her overall personality, since her primary source of happiness doesn't really come from the more positive stuff, as if she's '''shamelessly''' messing with others [[ForTheEvulz just because she can]].
882* MotorMouth: She can go on endlessly once she starts.
883* OddCouple: Her ex-boyfriend Antonio is some Neanderthal-like alien who talks in HulkSpeak, while she is a young, fairly attractive woman from a MageSpecies.
884* OddNameOut: Among her cousins, who are named Ben, Gwen, and Ken, Sunny's name sticks out.
885* PaletteSwap: Downplayed in her debut appearance, where she at least had a different outfit to better distinguish her from Gwen. In ''Omniverse'', her design is just a straight recolor of Gwen's.
886* SpoiledBrat: Verdona calls her a spoiled brat after she steps into her and Gwen's fight.
887* TokenEvilTeammate: Of the Anodites in Gwen's family and Max's grandkids. She's more chaotic than straight up evil though.
888* UncannyFamilyResemblance: She's essentially a brunette version of her first cousin, Gwen.

897A young ChildProdigy who is responsible exposing Ben's identity in ''[[WesternAnimation/Ben10UltimateAlien Ultimate Alien]]''. A big fan of Ben and his exploits, he was able to deduce after years of investigation that all alien forms were actually one single shapeshifting person. He then made the information public, assuming Ben would enjoy the fame. Though the team was initially uncomfortable with this, Ben comes to befriend him, and frequently asks for his help in searching for information.
898----
899* ActionSurvivor: Particularly in "The Big Story".
900* AlliterativeName: '''J'''immy '''J'''ones.
901** When we see his future self, we find out his middle name is '''J'''onah.
902* AndThenJohnWasAZombie: Appears as part of the montage of people turning into Esoterica in "The Ultimate Enemy, Part 1"
903* BadassNormal: Reveals himself to be one in "The Big Story", where he singlehandedly saves Ben, Gwen, and Kevin...multiple times.
904* BrokenMasquerade: Exposes Ben's identity to the world, but thought he would enjoy the fame (which he does).
905* CharacterisationMarchesOn: In ''Ultimate Alien'', Ben and him got along pretty well, and he would often be asked help thanks to his informatic skills. When he comes back in ''Omniverse'', Ben now inexplicably treats him as an annoying obsessive fan and refuses his help.
906* ChildProdigy: Deduced that Ben and the aliens were one and the same after years of investigating, and is skilled enough with computers to hack a military base camera. He's ''ten''.
907* ADayInTheLimelight: "The Big Story" focuses primarily on him.
908* DidntThinkThisThrough: Justified due to his age and thus, a WideEyedIdealist. Him revealing Ben's identity to the world was rooted out of respect for his heroics and believe that he deserves the public fame. However, he never once thought of the obvious problems that that kind of attention would bring in a ''lot'' of problems to Ben's life and his loved ones.
909* ImYourBiggestFan: Toward Ben.
910* InconsistentColoring: In ''Omniverse'', he has reddish-brown eyes.
911* MeaningfulName:
912** He's named for two well-known sidekicks, ''Jimmy'' Olsen from ComicBook/{{Superman}} and Rick ''Jones'' from ComicBook/TheIncredibleHulk.
913** His future self introduces himself as "J. Jonah Jones", a nod to ComicBook/SpiderMan character J. Jonah Jameson.
914* MissionControl: Often fills this role for Ben when he shows up.
915* SpottingTheThread: One of the reasons he figure it out Ben's identity is noticing that his alien transformations all have the ''Omnitrix symbol'' on some part of their bodies, allowing him to follow the pattern from there. Possibly a subtle TakeThat as beforehand, nobody is able to differentiate between Ben's alien transformations and similar-looking ones.
916* UnwittingPawn: "The Big Story" all but confirms that [[NiceJobBreakingItHero Jimmy's investigations were the very thing that got Will Harangue his big start.]]
917* UnwittingInstigatorOfDoom: His ratting out Ben's secret put a strain on Ben and Julie's relationship, was a factor behind Captain Nemesis going crazy and Zombozo targeting Ben's family in revenge.
918* WideEyedIdealist: He had no idea revealing Ben's identity might cause him so many problems; he merely thought Ben deserved to be famous for what he had done all the time.
919* YouthfulFreckles: He has these in ''Omniverse''.

928A mysterious girl met by Ben, Gwen and Kevin during vacation. She arrived on Earth in a space pod, with no memory of who she was besides her name. Ben started developing an attraction to her when it turned out she was being hunted by Sunder for unknown reasons. [[spoiler:It's eventually revealed she was the Unitrix, a pre-Omnitrix prototype developed by Azmuth with the ability to absorb DNA from living beings and stock it inside itself. When arriving on Earth, she assimilated Gwen's DNA (the first person who touched her pod), causing her to turn into a female human. Sunder was actually sent by Azmuth to retrieve her after she had been missing. Though initially intending to turn her back into a device, Azmuth agreed, after a short argument with Ben, to keep her as an assistant instead.]]

930* AnimalisticAbilities: Eunice has the ability to absorb and contain the DNA of various species without changing her form. She has been shown replicating the jumping ability of a rabbit, the strength of a bear and the flexibility of a snake. Eunice has two main weaknesses; she can only possess another animal or alien's ability for ten minutes and she can only absorb one creature's DNA at a time.

955Ben's LoveInterest introduced in ''WesternAnimation/Ben10AlienForce''. Julie was originally a girl Ben met following one of his soccer matches. The two developed a quick interest in each other, but Ben started hesitating to make any approach, afraid she might reject him if she found out about the Omnitrix. When this eventually happened during their first date, Julie turned out to not be scared of him, and they ended up in a relationship. Though non-powered at first, Julie can rely on the support of Ship, a Galvanic Mechamorph pet she met and tamed after her first date with Ben, to assist her in fights.
956----
957%%* ActionSurvivor
958* BattleCouple: With Ben, especially after getting Ship. Subverted, however, because despite being involved in Ben's heroism several times and having Ship to help her fight, she's not into the whole "fight evil to save the world" bit.
959* BeautyEqualsGoodness[=/=]MsFanservice: Since her first appearance, Julie is very sweet, cute, beautiful, good looking and attractive.
960* BoundAndGagged: In "Revenge of the Swarm". [[spoiler:By Elena, of all people.]]
961* CompetitionFreak: In ''[[WesternAnimation/Ben10UltimateAlien Ultimate Alien]]''.
962* DatingWhatDaddyHates: It's shown in "Ultimate Alien" her father does not approve of Ben.
963* DerailingLoveInterests: Julie has become much less nice since the start of ''Ultimate Alien''. Some of this is having to deal with Ben being famous (it was very justified in the episode with Captain Nemesis), but she's showing new traits that weren't originally present such as being [[CompetitionFreak overly competitive]] and [[HairTriggerTemper short-tempered]], likely as a misguided attempt at giving her more flaws.
964** She joined what was effectively a cult in "Flame Keepers Circle". She thought it was a corporation that was trying to improve people's lives by introducing alien tech at a faster rate than the Plumbers wanted (despite Kevin and Ben both warning her that such an act typically destabilized planets). It was really a bunch of crazy people worshipping Vilgax and it was ridiculously clear too, but she grabbed the IdiotBall firmly until it was beyond obvious she was wrong.
965*** And yet in the next episode they [[spoiler:brought back Elena, crazier than ever, and had her impersonate Julie as a "perfect girlfriend" for Ben]] as a sort of TakeThat to shippers who hate Julie for reasons like her not accommodating Ben enough.
966*** ''Omniverse'' derailed her further to justify her break up with Ben: it's stated she didn't really like smoothies and was just faking liking them to please Ben ([[SeriesContinuityError even though ''Alien Force'' featured her going to Mr. Smoothy of her own accord while Ben was light-years away]]).
967* FreakyIsCool: Ben initially was afraid to tell her about the Omnitrix, fearing his ability to shapeshift into monsters would freak her out. Much to his surprise, when she ''does'' find out about it, she actually finds it "cool".
968%%* KidWithTheRemoteControl: Ship.
969* LoveInterest: To Ben during ''Alien Force'' and ''Ultimate Alien''. They unintentionally broke up prior to the ''Omniverse'' episode "Rules of Engagement".
970* MagicSkirt: She could rival [[WesternAnimation/SupermanTheAnimatedSeries Lois Lane]] in this department. Even when she is playing tennis, the skirt barely flutters.
971** A particularly egregious example in her ''Omniverse'' appearance, where [[http://images.wikia.com/ben10/images/8/81/Rules_of_Engagement_%2820%29.png she can somehow sit without her panties being exposed]]
972* MoralityPet: She was the one who brought Ship back to reason when it was BrainwashedAndCrazy by the Forever Knights.
973** More importantly, [[spoiler:her intervention stopped Ben from going KnightTemplar at the end of ''[[WesternAnimation/Ben10UltimateAlien Ultimate Alien]]'']].
974* NiceGirl: At the start, she's very much a pleasant person, she wasn't afraid of Ben's alien forms and adopted the Mechamorph ship as a pet. During Ultimate Alien, she starts showing less nice traits, namely a short temper.
975* OfficialCouple: With Ben in ''Alien Force'' and ''Ultimate Alien''. However, they unintentionally broke up sometime before "Rules of Engagement" in ''Omniverse''.
976* OnlySaneWoman: Gwen states that Julie is the smartest of their group because she doesn't go looking for trouble, presumably including herself in that category.
977* WhatHappenedToTheMouse: She is nowhere to be seen for the first 20 episodes of ''Omniverse'', with a number of Ben's offhand comments suggesting he is once again single.
978* PinkMeansFeminine: Her clothes mostly consist of pink and white when in her regular attire.
979%%* PluckyGirl
980* PutOnABus: Julie only appears in a single episode of ''Omniverse'' "Rules of Engagement" in which she and Ben break up, and she gets a new boyfriend. WordOfGod made it known that she will not be returning again outside of a nonspeaking cameo and has actually gone on record that Ben will ultimately end up with Kai anyway so there's absolutely no chance of Julie and Ben getting back together again.
981* SatelliteLoveInterest: Initially appeared out of the blue (not helped by the fact many fans felt she was introduced just to get rid of the IncestSubtext between Ben and Gwen.); [[CharacterDevelopment she gets better over time]].
982* SixthRanger: Sort of; even in the UAF era, she takes much less part in the story than most characters. She still helps Ben and the others on occasion.
983* TookALevelInBadass: Getting Ship helped with this, as he can turn into PoweredArmor for her. She's also quite adept with certain weapons.
984* TookALevelInJerkass: See DerailingLoveInterests above.
985** She ''finally'' shows up again in "Rules of Engagement"....with a new boyfriend. In the same episode, it's explained in a flashback that Ben accidentally broke up with her during a phone call. At the end of it, she is PutOnABus for good, save for a cameo toward the end of the series.

995A small, dog-smart Galvanic Mecamorph (Upgrade's species) generated by Baz-l when he accidentally crashed on Earth. Ship was intended to find a Plumber and bring him for help; unfortunately, it mistook Ben's Omnitrix for a Plumber's badge, and, since it was unable to speak, had to try to get Ben's attention by attacking him and wrecking his date with Julie. Eventually, it succeeded in leading them to the ship, and they saved Baz-l in time. While he was leaving, Baz-l decided to leave Ship with them. It then developed a bond with Julie, effectively becoming her pet and main means of self-defense.

1005* PokemonSpeak: When created by Baz-l, he was sent to look for help in order to deal with the latter's ship being about to destroy. Due to his limited intelligence, however, the only thing he could say to do this was "ship", repeated over and over again. When he was adopted by Julie and Ben, this became his name.

1047* AllLoveIsUnrequited: His crush for Gwen; he just doesn't stand a chance against Kevin.
1048* AmazonChaser: Is attracted to Gwen, and compares her to a princess who rescued him in an MMORPG that he plays.
1049* AscendedExtra: He appeared only once in the Original Series during the Negative 10 two-parter. ''Alien Force'' made him a member of the Plumber's Helpers.
1050* BadassBookworm: He can use his knowledge and his powers to [[InstantArmor assemble a robot suit]], operate complex technology and create weapons capable of reproducing the Omnitrix's ability to heal genetic damages.
1051* CharacterizationMarchesOn: His crush for Gwen didn't show up until ''Alien Force''.
1052* DudeLooksLikeALady: [[https://static.tvtropes.org/pmwiki/pub/images/cooper_4146.png In the Original Series, his long hair made him seriously look like a little girl]]. Not so much anymore in the sequels.
1053* GlowingEyesOfDoom: Whenever he uses his powers.
1054* HeIsAllGrownUp: In ''Ultimate Alien'', [[MrFanservice he grew about two feet and went up to about a nine.]]
1055* HopelessSuitor: For Gwen.
1056* InstantArmor: Which he assembles for combat.
1057* LongHairedPrettyBoy: In the Original Series and ''Ultimate Alien''.
1058* OlderThanHeLooks: In ''Alien Force'' at least. His height makes him look like a little kid, but he's only a year younger than Ben and Gwen. Subverted in ''Ultimate Alien'' where he has a growth spurt and becomes the tallest member on the team.
1059* PutOnTheBus: He's completely absent during ''Omniverse'', with his only appearance being from a flashback episode that takes place five years prior.
1060* TechnoWizard: A subset of having {{Technopathy}} powers.
1061* TokenHuman: Unlike the others, Cooper is not half-alien, and is merely a mutant.
1062* TookALevelInBadass: In addition to a level in good looks.
1063* TookALevelInCheerfulness: While he was TheStoic in the Original Series, he's far more expressive and cheerful from ''Alien Force'' onward.

1070* AlliterativeName: '''A'''lan '''A'''lbright.
1071* ButtMonkey: He is often treated as the weakest member of his team, especially by Manny.
1072* CharacterizationMarchesOn: Alan was initially introduced as a shy kid, lacking self-confidence, and the youngest of the group. When he comes back to ''Omniverse'', he is now much more hot-headed, snarkier, and the closest thing the group has to a leader [[spoiler:after Pierce's death]].
1073* CharacterDevelopment: See GrewASpine below.
1074* ChestBlaster: Sort of, he fired a ball of flame from the chest in his debut appearance.
1075* CursedWithAwesome: He felt that way about himself at first, but Ben helped him grow out of it.
1076* CuteBruiser: In ''Alien Force'' and ''Ultimate Alien'', he may be cute and beautiful in his human form, but he's very feisty and a firecracker.
1077* FlamingHair: Standard for Pyronites.
1078* GrewASpine: In his early appearances, he was very uncertain of himself, but he progressively becomes more confident. Manny even literally tells him to "grow a spine" in "Above and Beyond" in which he later learns to do.
1079* KidHero: 10 years old in Alien Force, 11 in Ultimate Alien and Omniverse.
1080* HowDoIShootWeb: In his first appearance, he had some serious trouble learning how to fly. Ben eventually taught him a few tricks to help.
1081* NotSoDifferentRemark: Ben stated that Alan reminded him of a younger version of himself, especially in the sense how they [[HowDoIShootWeb both had trouble controlling their power]].
1082* NiceGuy: In ''Alien Force'' and ''Ultimate Alien'', he's more mature, kinder, sweeter and very brave.
1083* PintSizedPowerhouse: He is physically the smallest and youngest member of the team, but his powers give him the potential to be the strongest of all. However he often had to be coaxed into this by support from his teammates. Ben has acknowledged this and has called him "a powerhouse" before.
1084* PlayingWithFire: Due to his Pyronite powers.
1085* PrettyBoy: Mixed with MrFanservice in his human form in ''Alien Force'' and ''Ultimate Alien''.
1086* TheScapegoat: He's been made this by the sheriff of his hometown during his debut. It's somewhat understandable when they were blaming the serial arson cases on him, less so when the sheriff sees the Highbreed weather tower and immediately comes to the [[SarcasmMode completely logical conclusion]] that the kid who's in his early teens at best somehow constructed a massive device, ''by himself'', to drain the heat from the area to feed his powers.
1087* SixthRanger: He's the newest member of the Plumbers Helpers' (other than Cooper).
1088* TagAlongKid: In ''Alien Force'' he was the youngest member, and was treated as such.
1089* ThisIsUnforgivable: Even after Kevin gets cured of his mutation, Alan makes it clear he's less than happy to see him again because their last encounter had Kevin absorbing his powers.
1090* YouAreBetterThanYouThinkYouAre: Is taught this by Ben and Helen.
1091** Subverted in "Above and Beyond" when Ben (as Big Chill), while pretending to be evil, tells him:
1092-->'''Big Chill:''' You're out of your league Alan, [[ButtMonkey you're the weakest one and you know it]]. Your teammates know it too.

1096-> Manny Armstrong voiced by Creator/KharyPayton
1097-> Helen Wheels voiced by Creator/JulietLandau
1098
1099%%%* ArrogantKungFuGuy: Manny, played straight.
1100* AxCrazy: Manny is reckless, impulsive, and loves to bash or shoot things.
1101%% Doesn't explain what the reactions are. * BerserkButton:
1102%% ** For Helen, whenever someone brought up Pierce.
1103%% ** Manny also doesn't take Kevin insulting his appearance too well.
1104* BloodKnight: Manny lives for combat, and relishes every second of it.
1105* CloudcuckooLandersMinder: Even though he isn't technically a CloudcuckooLander, Helen still acts as one to Manny, as she holds him back from his acts of immaturity.
1106* CoolBigSis: Helen acts as one to Alan and Cooper, giving them guidance and encouragement.
1107* DidntThinkThisThrough: Given their complete lack of context for aliens in the first place, simply assuming every freaky being they encountered was a [=DNAlien=], they ended up tossing a bunch of innocent aliens, hybrids, and other Plumber's kids like themselves into the Null Void while thinking they were ''disintegrating them'', to the point that Pierce had a MyGodWhatHaveIDone moment after one of them had flashed a Plumber's Badge in the process. To Helen and Manny's credit, they willingly jump into the Null Void themselves to rectify their mistake.
1108* DumbMuscle: Manny is the kind of guy who thinks with his fists, rather than use his brain for anything.
1109* GunsAkimbo: Four guns in total, with one for each arm.
1110* {{Expy}}: Manny and Helen are half-Tetramand (Fourarms) and half-Kineceleran ([=XLR8=]).
1111* HypocriticalHumor: Manny has a tendency to call his enemies "dirty alien freaks" (or something similar), even though his own appearance holds little traces of humanity. This is played with during an exchange of insults he has with Kevin when they first meet.
1112-->'''Manny:''' They're all dirty alien freaks.
1113-->'''Kevin:''' That's a laugh coming from a Halloween reject like you.
1114-->('' later on'')
1115-->'''Manny:''' Think you're funny?
1116-->'''Kevin:''' Hey you're the comedian. You even have the face for it.
1117* JerkWithAHeartOfGold: Manny comes off as being very rude and obnoxious, but will still put the lives of others before his own when the time is right.
1118* ManChild: Manny is physically the largest helper, but the most immature of them all.
1119** Lampshaded in "Vengeance of Vilgax Part 1" where he keeps "calling shotgun" to ride in the front seat. The other helpers shake their heads or {{facepalm}} in response.
1120* MirrorCharacter: Manny is this to Kevin (reckless, rude, and eager to fight) while Helen is this to Gwen (kind, compassionate, and cautious). Fittingly each of them is pitted against their counterparts when they first meet.
1121* MultiArmedAndDangerous: Four arms means four guns. You probably don't want to be on the receiving end of Manny's blaster fire.
1122* OutOfFocus: By ''Ultimate Alien'' they are the only members of the team to stop making appearances, even though their voice actors still appeared on the show.
1123* PinkGirlBlueBoy: Gender inverted for Manny and Helen.
1124* RedOniBlueOni: Manny and Helen fit this perfectly, and have even been ColourCodedForYourConvenience.
1125* SavvyGuyEnergeticGirl: Gender inverted. Manny is the impulsive one and Helen keeps him in check.
1126* ScaryBlackMan: Manny. [[spoiler:He was black when he was human.]] Fitting since he's voiced by Creator/KharyPayton, who usually voices black characters.
1127* ShipTease: Throughout the series, it's hinted the two of them are an item.
1128* TheSmurfettePrinciple: Helen is the only female on the team.
1129* SuperSpeed[=/=]SuperStrength: Helen and Manny's respective default powers, thanks to their alien heritage [[spoiler:or at least what was originally thought to be their heritage.]]
1130* TeamMom: Helen serves as this, acting as a CoolBigSis to Alan and Cooper, while restraining the immature Manny from acting recklessly.
1131* VitriolicBestBuds: Manny with Pierce. According to Helen, they argued on every mission, but are later shown to be true once Pierce returns.
1132* YoungerThanHeLooks: Contrary to what his size suggests, Manny's still a teenager.

1138* BackForTheDead: After having his powers temporally absorbed by Kevin, he returns in ''Ultimate Alien'' [[spoiler:only to be killed]].
1139* DroppedABridgeOnHim: [[spoiler:Pierce is one of the Forever Knights' first victims in "The Purge".]]
1140* {{Expy}}: Possibly unintentional, but his design and powers bear striking similarities with a one-shot character named Porcupine from the Original Series who appeared in the episode "Ready to Rumble".
1141* GoryDiscretionShot: [[spoiler:His death at the hands of the Forever Knights wasn't shown.]]
1142* KilledOffForReal: [[spoiler:He is one of the few prominent characters to actually die.]]
1143* MirrorCharacter: To Ben, which is specifically mentioned by Helen, with both being logical and calculating and serving as the [[TheLeader team leaders]] of their squads. As Ben didn't initially get a chance to duke it out with his Plumbers Helper counterpart like Gwen and Kevin did, he is later given the opportunity when the two meet in "Voided".
1144* SacrificialLion: [[spoiler:Pierce's cold-blooded murder by the Forever Knights showed just how merciless and dangerous they'd become.]]

1151
1152[[quoteright:292:https://static.tvtropes.org/pmwiki/pub/images/Reinrassic_2140.png]]
1153
1154A Highbreed lord who, following a fight around a portal, accidentally ended up stranded with Ben on a hostile desert planet. With no other choice, the two had to team up to find their way home and survive. Though initially as racist and aggressive as the others of his kind, Reinrassig progressively befriended Ben, reaching a point where he lost his hand protecting him. Ben reattached it using Swampfire's regenerative abilities, but this altered Reinrassig's DNA in the process. This, plus the realization that he had been [[HumanityIsInfectious infected]] by Ben's human emotions, led Reinrassig to exile himself on the planet, feeling he would no longer be welcome among his people. [[spoiler:He eventually came to realize this was actually a way to save his species, and returned to his home world just in time to convince them not to commit mass suicide after Ben altered their DNA. Impressed by his lucidity, his people then named him Highbreed Supreme, and he stopped the war, then concentrating his efforts in reintegrating his species to the universe.]]
1155----
1156* AnArmAndALeg: His hand gets amputated by an attacking Rodilia Dentia (scarab-like alien). Ben uses Swampfire to change his amputated hand to the DNA of a Methanosian, giving him a HealingFactor to save his arm.
1157* ComplainingAboutRescuesTheyDontLike: During his episode, Ben at one point saves him from a swarm of killer bugs by grabbing his arm as Swampfire. Once the danger is passed, he immediately starts yelling about how Ben dared touch him. Ben even calls him out for it.
1158* {{Determinator}}: Was forced to team up with Ben on a planet where the climate was weakening him (Highbreeds survive better in cold climates) with limited supplies of water. He ''still'' survived. [[spoiler:Even after Ben left, he still found a way to come back on his homeworld of his own.]]
1159* DontYouDarePityMe: Repeatedly rejects Ben's attempts to be nice to him during their team-up. [[spoiler:He gets better]].
1160-->"I do not take charity from vermin!"
1161* EnemyMine: The entire premise of his first episode is that Ben and him end up trapped together on a hostile planet, forcing them to rely on each other to survive. Unfortunately for their friendship, a lifetime of ingrained xenophobia doesn't vanish overnight, and he chooses to remain behind on a hostile planet rather than "[[HumanityIsInfectious infect]]" the rest of his people.
1162* FantasticRacism: Initially, like all Highbreeds. He gets better.
1163* FireForgedFriends: Ben and him met in the middle of a battle, and both got teleported on a hostile planet. They ended up becoming friends.
1164* HeelRealization: [[spoiler: He has the start of one in his debut episode and fully realizes it off-screen, leading to him convincing the other Highbreed to change their ways later.]]
1165* HumanityIsInfectious: His whole first appearance revolves around this trope; deconstructed when he decides to stay exiled because he feels like he was corrupted. [[spoiler:Then reconstructed when he realizes the truth and convinces the other Highbreeds of the error of their ways.]]
1166* HypocriticalHumor: When offered by Ben to join him around the campfire and talk, he dismisses the idea as pointless and essentially says he doesn't want to talk. Very next minute, Ben gives him his name, and he answers by listing ''all'' [[TryToFitThatOnABusinessCard his name, titles, lineage and others]] until Ben interrupts him.
1167* IChooseToStay: [[spoiler:After his CharacterDevelopment, he deduces he has been [[HumanityIsInfectious infected by Ben]], and chose to not go back home, knowing full well he'd threaten his people's purity. [[ChangedMyMindKid It doesn't last.]]]]
1168* InSeriesNickname: Ben refers to him as "Reiny" to go around his TryToFitThatOnABusinessCard introduction.
1169* LiteralMinded: A minor case; he refers to Ben as Ben-Ben Tennyson due to Ben introducing himself as "Ben, Ben Tennyson". Other than that, he is perfectly able to understand expressions.
1170* MySpeciesDothProtestTooMuch: Averted; when first introduced, he was as arrogant and racist as any other Highbreed; it's only after befriending Ben that he became a better person. [[spoiler:And when he came back on his planet, he successfully convinced his people to share his opinion.]]
1171* ReasonableAuthorityFigure: [[spoiler: He's in charge of his race by the end of their invasion and seeking peace instead of trying to take every species with theirs since they had been SecretlyDying makes him a much more appealing Highbreed Supreme for the reconstituted Highbreed than their previous one.]]
1172* RedRightHand: Inverted; after he lost his hand saving Ben from a local predator, Ben uses Swampfire's regenerative abilities to heal his wound, leaving him with a green hand... only it's when they have befriended, so this is basically a sign he is a good guy.
1173* SmallRoleBigImpact: He only appears in three episodes in total, only one of which actually has him for most of the episode; however, he plays a key role in [[spoiler:ending the Highbreed War]].
1174* StabTheScorpion: At one point during their team up, Ben and him end up camping out for the night. Ben wakes up to see Reinrassig shooting at... the creature who was about to attack him.
1175* TokenHeroicOrc: While initially just as much a racist bigot as his peers, he is the first Highbreed to be portrayed sympathetically and receive CharacterDevelopment.
1176* TookALevelInKindness: Starts out as a generic racist Highbreed, but he and Ben eventually become FireForgedFriends, and he ends up [[spoiler:convincing his entire people to give up their SuicidalCosmicTemperTantrum and accept the other races after Ben uses their [=DNA=] to save the Highbreed species]].
1177* TryToFitThatOnABusinessCard: His complete name and titles is: Reinrassig III, seventh son of the Noble Highbreed House of Deralla, direct descendant of the Pure Blooded High Order of Rarsect. Ben goes with just calling him Reiny.
1178* YouHaveOutlivedYourUsefulness: [[spoiler:Subverted]]; he makes it very clear to Ben he intends to apply this trope on him once they no longer need to collaborate, [[spoiler:but they end up genuinely befriending each other]].

1187[[caption-width-right:319:[[LovableRogue Everyone's favourite Con Man]]]]
1188
1189One of Kevin's friends and former partners-in-crime. Argit is an alien ConMan who is usually seen attempting to make profit from any situation he can find, though he usually is harmless enough to not be considered by the main cast as a threat. Though he frequently double-cross Kevin in their deal, Kevin still considers him as a friend and frequently talks with him. He resembling a cross between a porcupine and opposum.
1190----
1191* AffablyEvil: He always acts friendly toward both Kevin, Ben, Gwen and Rook when he sees them, but he usually won't hesitate to double-cross them if he can save his skin or make profit by doing so.
1192%%* BarefootCartoonAnimal
1193* BullyingADragon: In "Andreas' Fault", he started trying to blackmail a ''[[AncientConspiracy Forever Knights]]'' castle with the help of Andreas. This worked for a short while, then a superior was sent to put some order...
1194* ChronicBackstabbingDisorder: And ''how''. Gwen describes him as "A con man who would sell his mother for lunch money" (According to Kevin's answer, [[NoodleIncident he actually did it]], [[BlackComedy and got a top price from her]]).
1195** This becomes a point of HypocriticalHumor when he accuses the Incurseans for double-crossing ''him'' in bargaining for the Annihilarg.
1196* ConMan: In almost every appearance, he's either pushing a scam, or trying to outrun the consequences of one.
1197* CorneredRattlesnake: As he himself says, he's only a threat when he's backed against the wall.
1198* CrouchingMoronHiddenBadass: It was out of fear, but he did defeat one of Dr. Psychobos's mutant To'kustars by shooting all of his quills at it. He also defeated Albedo as Ultimate Spidermonkey.
1199* DiminishingVillainThreat: In his first appearance, he was portrayed as an actual villain who, while not exactly a big threat, was still dangerous enough for Ben to require using Echo Echo against him. In all his following appearances in the sequels, he was portrayed as more comical character who would fail anyway, to the point he can no longer be classified as an antagonist by now. See HarmlessVillain.
1200* DirtyCoward: He can and will fight if really forced to, but he is in no way a fighter, and usually either tries to run away as much as possible, backstab his opponents, or just ask the Plumbers/the main cast for protection.
1201* TheDogBitesBack: He constantly tricks and double-cross Kevin, while still trying to act like his friend. In ''Ultimate Alien'', [[spoiler:a psychotic Kevin starts chasing him to get revenge on all the times he double-crossed him by the past]].
1202* EvenEvilHasStandards: In "The Ultimate Heist", he's not impressed when he hears that Rook has been trying to change Ben:
1203-->'''Argit''': Even I know you don't try to change a partner.
1204* EvilVersusOblivion: As shown in "So Long and Thanks For All the Smoothies", even Argit doesn't want the Universe to be destroyed.
1205-->'''Argit''': The Universe is where I keep all my stuff!
1206* ExtremeOmnivore: In "Cough It Up", he swallows the episode's MacGuffin for safekeeping. Not an example in itself, but when he's finally made to...well, [[TitleDrop cough it up]], he also coughs up a bunch of other objects that he apparently ate just because he was hungry.
1207* HarmlessVillain: In-story, he is technically a criminal, but the protagonists leave him free both because he is a friend of Kevin and because he isn't much of a threat.
1208* HazyFeelTurn: Argit flip-flops between friend and foe often, with the only consistency being that he does whatever is best for his own selfish interests.
1209* HoistByHisOwnPetard: His plans have a bad tendency to systematically backfire on him.
1210* IdiotBall: "Cough It Up", where Argit swallows the cube that Psyphon was after. When he's told it's a dehydrated Techadon Factory, he simply continues to mock Psyphon. When Ben of all people calls out on not knowing what dehydrated means, you know you did something wrong.
1211* {{Jerkass}}: He is capable of putting a nice façade, but he really is quite a jerk.
1212* JerkWithAHeartOfJerk: When Andreas apparently sacrifices himself to save him and the heroes, Argit appears to be honestly desperate... only to reveal he is actually mourning all the money he lost in the process. Kevin is ''not'' amused.
1213* KarmaHoudini: He constantly double-crosses Kevin and others, has manipulated poor Andreas into doing his bidding (and shows no true remorse when this apparently leads to Andreas' death), and [[spoiler:betrayed the rebellion to the Incurean invaders]]. The worst retribution he has ended up with was to be sent in prison a couple of times, only to be free again by the next episode. He never truly gets punished and Kevin ''keeps'' trusting him. Even worse after “Frogs of War”, where he actually managed to pass himself as a hero and became famous and loved by Undertown's population. Oh, and in “The End of An Era”, it's revealed he will end up ''President of Earth'' in the future.
1214* LovableTraitor: He is a unscrupulous rogue who will betray everyone for his own benefit, but he gets away with that in the eyes of some fans due to being hilarious.
1215** Though some parts still make him overlap with just being an obnoxious JerkAss, such as when he remorselessly manipulated Andreas to his own end, when he [[spoiler:betrayed the rebellion to Attea during the Incursean invasion]], or when he [[spoiler:was willing to sell a baby to be ''eaten'']].
1216* ManipulativeBastard: He acted like one toward Andreas. Though not an especially competent one, and it's pretty clear it worked only because Andreas wasn't the smartest.
1217* NotQuiteDead: An ''actual ability'' of his race; they possess the ability to temporarily stop their pulse to fake death. According to Ben, this is the only explanation as to how such an obnoxious species was able to survive as long as they have.
1218* OurPresidentsAreDifferent: In "The End of an Era", which takes place in Ben 10,000's time, it's revealed that Argit has become President of Earth.
1219-->'''Rook:''' [[LampshadeHanging How did you get elected]]?
1220* PetTheDog: He actually tries to warn Ben about what will happen if he defeats Looma in "Many Happy Returns", but is silenced by Kevin.
1221** In "The Ultimate Heist", he [[spoiler:saves Ben by defeating Albedo, even though he could have easily fled and left him to his fate. Granted, he ''still'' tries to make profit of it after that, but it's still worth noticing]].
1222** In "Weapon XI", when [[spoiler:the heroes wonder whether Kevin, who was revealed to be a sleeper agent of the Rooters, ever truly meant to be their friend, Argit is the one who repeatedly and honestly insists that they believe that there's still good in him, even saying that they all owe it to Kevin to give him a chance. Keep in mind, the last time Kevin went rogue, he tried to ''kill'' him. Despite his cowardly and pragmatic personality, he gives his oldest friend the benefit of the doubt]]. Granted, he tries to use ''[[ChronicBackstabbingDisorder himself]]'' as a similar example, which doesn't exactly help his case... [[spoiler:but he ended up being right]].
1223** Also, in a flashback, [[spoiler:a young Argit saves the Tennyson family's lives from a psychotic Kevin]].
1224* PlayingPossum: His species has the ability of doing this. Ben knows he is faking it when his friends legitimately thought he died once.
1225* RatMen: [[AstonishinglyAppropriateAppearance A hybrid rodent of sorts.]]
1226* RewardedAsATraitorDeserves: Gets on the receiving end of a non-lethal version in "The Frogs of War" when [[spoiler:he betrays the resistance to Attea]].
1227* TheSociopath: While not to the same degree as many of Ben's major villains, Argit still qualifies as one. To begin with, he only cares about himself and money, and will use and [[ChronicBackstabbingDisorder betray]] anyone to get it, to the extent Kevin confirms that he ''sold his own mother'' for a profit. This trait is best shown in "Andreas' Fault"; where he takes advantage of Andreas' innocence to get him to work for him, and after Andreas sacrifices himself to save Argit and Ben's team, Argit is more concerned with the money he lost in the process and honestly [[EvilCannotComprehendGood doesn't seem to understand why Kevin would be disgusted with him]].
1228-->'''Argit''': Sometimes, I just don't get you, Kevin!
1229* SpikeShooter: Can launch spikes from his body, which are capable to knocking out whatever they hit.
1230* VillainWithGoodPublicity: In ''Omniverse'', thanks to the fame he got from defeating a Way Bad during the Incursean Invasion, he becomes a hero to the population of Undertown and creates his own enterprise, while still pursuing his illegal alien tech trade on a larger scale than before. He still remains fairly harmless though.

1239----
1240* AsteroidsMonster: Notably spawning a ''regular character'', Ship.
1241* JerkWithAHeartOfGold: Despite offering Ship to Ben and Julie in his first appearance, he attempts to take it back later just so he could get some credit for Ben's victory in the Highbreed war. He however accepts to give up on him when he sees that Julie and Ship have bonded. Later, when Julie tries to give him Ship back because she fears it likes him more, he voluntary acts like a jerk so Ship will go back to her.
1242* JerkWithAHeartOfJerk: Aptly described as a "total weasel" by the other characters. In his second appearance, he was going to sell Ship on the black market, even though Ship is technically his ''son''.
1243* TooDumbToLive: Twice; in his second appearance, he recruited the ''[[LeeroyJenkins Vreedle Brothers]]'' to bring Ship back alive. In his third appearance, while he is at the mercy of a bunch of fanatical alien mystics who accuse him to have profaned their sacred place, he outright tell them said sacred place is a mess to the point he thought it was just old ruins.

1256
1257The Andromeda Five are, as suggested by their name, five alien of different species from the Andromeda Galaxy. All of them had in common that they possessed the powers Osmosian criminal Aggregor required to absorb in order to get the abilities he needed for his scheme. As a result, all of them were kidnapped by him so he could take them to his planet, where he would have use a machine to absorb them permanently (instead of the usual temporary 10% of their actual powers). They succeeded in escaping during the travel, and ended up on Earth, where they split up so they could better escape to Aggregor. The first half of season 1 in ''[[WesternAnimation/Ben10UltimateAlien Ultimate Alien]]'' focus on Ben's team trying to help them go back home, causing Ben to scan all of them in the process. They included:
1258* '''Bivalvan''': a crustacean-like alien with [[MakingASplash the ability to produce and control water]]. The closest thing the group had to a leader. He provided the DNA for Ben's form '''Water Hazard'''.
1259* '''Galapagus''': a turtle-like alien with [[BlowYouAway wind-based and flight abilities]], as well as [[AntiMagic the ability to not be hurt by Mana]]. Galapagus was from a peaceful and innocent species, to the point he didn't even knew the concept of jail and lie before being captured. He provided the DNA for Ben's form '''Terraspin'''.
1260* '''P'andor''': A radioactive EnergyBeing [[SealedEvilInACan trapped inside a restraining armor]], [[PlayingWithFire with the ability to produce intense heat and melt metal by mere touch]]. [[TokenEvilTeammate Was the most aggressive and reckless of the three, and the only one to display true malice]]. He provided the DNA for Ben's form '''NRG'''.
1261* '''Andreas''': an armadillo-like armored alien [[TunnelKing with the ability to dig]] [[DishingOutDirt and produce powerful earthquakes by hitting the ground]]. [[DumbMuscle He was the strongest physically, but also the least intelligent of the three]], resulting in him shortly serving as an UnwittingPawn to Argit. He provided the DNA for Ben's form '''Armordrillo'''.
1262* '''Ra'ad''': a jellyfish-like alien with [[ShockAndAwe electrokinesis power]], and [[TheSmartGuy one of the smartest in the group]]. While not as malicious as P'andor, Ra'ad was still individualist and willing to KickTheDog if it allowed him to save his skin from Aggregor. He eventually got better. He provided the DNA for Ben's form '''[=AmpFibian=]'''.
1263
1264%%Tropes specific to their involvement in the Aggregor story arc as opposed to being Ben's alien forms go here.
1265----
1266* AerithAndBob: All of them have relatively exotic and alien sounding names - except for Andreas.
1267* AlienBlood: Near the end of the episode ''Andreas' Fault'', [[https://vignette.wikia.nocookie.net/ben10/images/e/ee/AF_%28508%29.png/revision/latest?cb=20150901203457 an injured Andreas is depicted with dark grey blood]].
1268* AntiHero: Bivalvan seems to be a Type III; P'andor is a Type IV, and Ra'ad starts out as a Type IV, but gets better.
1269* CannotTellALie: Galapegus. But he learns.
1270* ComboPlatterPowers: Ra'ad throws lighting, has telepathy, enters electronic devices by ''becoming'' lightning and enters ''pretty much anything else'' by becoming liquid. [[spoiler:And bodyjacking, which Ben himself never bothered with but ''King Xarion'' can somehow channel this to put his own soul in the body of Dr. Viktor.]]
1271* ContainmentClothing: P'andor's armor acts as a PowerLimiter to prevent his powers from affecting others.
1272* DumbMuscle: Andreas isn't the sharpest tool in the shed.
1273* ElementalPowers:
1274** BlowYouAway: Galapagus
1275** DishingOutDirt: Andreas
1276** MakingASplash: Bivalvan
1277** PlayingWithFire: P'andor
1278** ShockAndAwe: Ra'ad
1279* EnergyBeing: P'andor’s real body is composed entirely of radiation.
1280* HeroicSacrifice: Andreas almost goes out using his powers to stop an overloaded weapon that would’ve killed several hundred people. [[spoiler: Unfortunately, Aggregor is the first to find him afterwards]].
1281* HuskyRusskie: P'andor's armor gives him this appearance, but it's {{Subverted}} by his actual, rather skinny appearance and ''DoubleSubverted'' when he consumes enough radiation to become massive.
1282* LetsGetDangerous: Galapagus. He is the nicest of the five and the least aggressive, but when he first decides to fight, he manage to actually hit Aggregor.
1283* LivingMacGuffin: All of them are sought after by Aggregor for their abilities.
1284* MeaningfulName:
1285** Bivalvan's name comes from Bivalvia, a class of sea mollusks such as clams and oysters.
1286** Galapagus takes his name from the well-known Galapagos tortoise (and possibly the Galapagos Islands since they, like him, have remained uncorrupted by the outside world).
1287** P'andor refers the story of Pandora's Box.
1288** Andreas is obviously a reference to the San Andreas Fault.
1289** Ra'ad's name comes from the Arabic word for thunder.
1290* SealedEvilInACan: P'andor was clearly trapped in his armor as a way to prevent him from wreaking havoc. The only thing that can break it open is Taydenite.
1291* SharingABody: Rather like Ghostfreak, Ben's first use of Ra'ad leads to this temporarily.
1292* TokenEvilTeammate: P'andor, having been a criminal imprisoned by his people in his suit before he was captured, and is the only one of the Andromeda Five who actually wants to ''stay'' on Earth to feed off of the radioactive sources it has. After he's defeated by Ben and Kevin, the Plumbers explicitly have to deport P'andor back to his home planet so that he doesn't cause trouble on Earth again.
1293* TookALevelInJerkass: With the exceptions of Galapagus and Andreas, the Andromeda Five become rather surly and outright villainous when Ben and company encounter them.
1294** Bivalvan was perfectly willing to blow up a good chunk of Florida just to get his ship working again, and he even broke into some government facilities to get resources for it.
1295** While P'andor was never a nice guy in the first place, he goes from being an arrogant and condescending jackass who wants to bust his way out off Aggregor's ship, to stifiling Earth criminals of payment and feeding off all the radiation he can find no matter who gets in his way.
1296** Ra'ad initially seems calm and collected when trying to escape from Aggregor, but he's quite hostile to Ben due to realizing he's accidentally responsible for getting the rest of his companions recaptured, and later tries to take over Ben's body to save his own skin. He eventually has a change of heart after Kevin gives him a TheReasonYouSuckSpeech.
1297* TunnelKing: Andreas.
1298* WithGreatPowerComesGreatInsanity: P'andor's incredible power has rendered him ''quite'' unstable. It gets ''worse'' once he leaves the armor holding him back.

1304
1305[[quoteright:224:https://static.tvtropes.org/pmwiki/pub/images/Kwarrel_2207.png]]
1306
1307An old Alien prisoner Kevin met during his time in the Null Void Incarcecon. Kwarrel played a major part in Kevin's life by taking him under his wings, helping him to turn back to his human form and learning him a safe way to use his power, such allowing him to go on the path of redemption. Unfortunately, he was killed by prison guard Morgg while helping Kevin to escape the Null Void.
1308----
1309* BadassNormal: he apparently had no special power or ability, but he was strong enough to handle the original mutated form of Kevin in a hand-to-hand fight.
1310* CoolOldGuy: He was such a nice and cool guy that you have to wonder why he ended up in prison in the first place.
1311** [[WordOfGod Dwayne McDuffie]] says that Kwarrel lived a full life and didn't reveal what caused him to end up in the Null Void, but hinted that ''"it was '''bad'''".''
1312* GentleGiant: A life inside the Null Void has rendered someone who was very likely a brutish bruiser into someone who honestly seemed like he didn't deserve to be there anymore.
1313* HeroicSacrifice: Gave his life to keep Morgg busy and allow Kevin to escape Incarcecon.
1314* MentorOccupationalHazard: He helped Kevin grow as a person... and died to ensure he could escape.
1315* TheMentor: To Kevin. He was the one who helped him to get rid of his psychosis and original mutant form, as well as teach him how to use his new powers.
1316* PosthumousCharacter: His first and so far only appearance was in season 1 of Ultimate Alien; he actually died in the gap between the original series and Alien Force.
1317* RubberForeheadAliens: Looks like a human with [[AmazingTechnicolorPopulation grey skin]] and PointyEars.
1318* SmallRoleBigImpact: A PosthumousCharacter who only appeared in one episode in a flashback, but he was the one who cured Kevin of his insanity, making him a key factor of his HeelFaceTurn. He and his role in Kevin's backstory is noticeably one of the few elements ''not'' retconned in ''Omniverse''.

1328* TheCameo: Briefly appears in "The Most Dangerous Game Show."
1329* CelebrityIsOverrated: You have no idea...

1331%%* EveryoneLovesBlondes
1332%%* FallenPrincess
1333* HiddenDepths: She was initially introduced as a shallow character serving as a reference to Twilight and a potential rival to Julie for Ben's affection. Her second appearance explores her further, revealing [[spoiler:she had a harsh childhood, suffers a major lack of affection and is subject to a StockholmSyndrome.]] Much like Captain Nemesis, ''Omniverse'' undoes this, and she's back to being a ditzy actress.
1334%%* ImportantHaircut
1335* InkSuitActor: When she dyes her hair and shortens it, she looks much more like Tara Platt, her voice actress.
1336* ParentalNeglect: [[spoiler:The reason why she ran away to become a celebrity.]]
1337* {{Retcon}}: In "The Most Dangerous Game Show," [[spoiler:her hair is back to it's original color and length, and her movie career is still going (lending further credence to the fan theory that the events of "Catch A Falling Star" never happened).]]
1338* RomanticFalseLead: To Ben, sort of. It was actually very short, and it was quite obvious Ben didn't really love her; he actually wasn't even considering their relationship as a date, believing him spending time with her was platonic and doing it because it was apparently good for their image.
1339%%* SoBeautifulItsACurse
1340* StockholmSyndrome: [[spoiler:Toward Captain Nemesis. She even has an affair with him. A rare animated example that is ''not'' played for laughs.]]

1348
1349A character introduced in the Film/Ben10AlienSwarm movie. Elena was one of Ben's {{Childhood Friend}}s when he was 13, and [[ChildhoodFriendRomance Ben's first crush]] (apparently excluding Kai Green). She comes back during Alien Swarm, where it's revealed her father was a Plumber who studied the Hive's nanochip.
1350----
1351* BadassBookworm: We don't learn it until ''Ultimate Alien'', but she is as good of a scientist as her father.
1352* BadassNormal: One of the few Plumbers' Kids to not have any power whatsoever. She still was a great pupil at the Plumber Academy and, according to her instructor, would have been a formidable recruit had she not abandoned her formation.
1353* BrainyBrunette: Ultimate Alien shows that she was able to recreate and mass-produce the nanotech chips.
1354* TheCameo: In "The Most Dangerous Game Show."
1355* ChildhoodFriendRomance: Is stated by Gwen to have been Ben’s first crush.
1356* ClearMyName: Her goal in ''Film/Ben10AlienSwarm'' is to clear her family's name of her father's supposed crime.
1357* EmpoweredBadassNormal: [[spoiler:After the nanochips infected her.]]
1358* FaceHeelTurn: [[spoiler:Being corrupted by the nanochips and rejected by Ben will do that to you]].
1359* HeroicSacrifice: [[spoiler:Subverted; she appears to do it in "Revenge of the Swarm", but it later turns out she survived.]]
1360* LoveMakesYouEvil: [[spoiler:Well, that can happen when you get infested with some weird alien nanochips that distort your deepest wishes...]]
1361* SatelliteLoveInterest: [[spoiler:With her Hive persona; after all the damages she went through, being with Ben became her only driving purpose, turning her into a {{Yandere}} and leading her to attempt to alternate herself just to please Ben. Lampshaded by Ben.]]
1362* UncannyValleyGirl: [[spoiler:In Ultimate Alien.]]
1363* UnexplainedRecovery: [[spoiler:She returns in the third-to-last episode of ''Omniverse''...all cured of the Hive. How did that happen?

1364** [[spoiler:[[http://ecx.images-amazon.com/images/I/51TikJCx20L._SL500_AA300_.jpg A graphic novel.]] has since been published showing more about her, but it ended with her still infected and didn't explain how she was cured either.]]
1365* UnluckyChildhoodFriend: [[spoiler:She retained feelings for Ben even after they stopped being together, but apparently repressed it. Then the Hive takes over her and causes it to resurface. The result... [[{{Yandere}} isn't pretty]].]]
1366* VoluntaryShapeshifting: [[spoiler:Thanks to the nanochips. She used it to assume Julie's appearance and try to pass time with Ben.]]

1376
1377A military officer first introduced in WesternAnimation/Ben10UltimateAlien who serves as the protagonists' main contact with the Army over the course of the show.
1378----
1379* BeneathTheMask: The few first times we see him, he is portrayed as a rather reasonable person by military standards in fiction, accepting the protagonists' help and fully cooperating with them (though he does display some more aggressive tendencies when he suggested to nuke the place where Aggregor was hiding). We only get to learn about his KnightTemplar tendencies in "Prisoner 775 is missing".
1380* BrokenPedestal: Seems to be this to Max when we find out about his KnightTemplar tendencies.
1381* EvenEvilHasLovedOnes: Has a wife and son he genuinely loves and sent agents to search for his sister after she disappeared.
1382* IDidWhatIHadToDo: His justification for what he did in Area 51.
1383* KarmaHoudini: He gets away with his imprisonment of aliens with nothing else than having his family threatened by one of his vindictive prisoners. To make things worst, this ''still'' wasn't enough for him to learn his lesson.
1384* KnightTemplar: He imprisoned over 700 alien in Area 51 because they "might" become a threat to Earth.
1385* MeaningfulName ''Rozum'' is Czech, Polish, and Slovak for ''reason'' (as in thinking capacity).
1386* ReasonableAuthorityFigure: Appears to be this at first; flashbacks suggest he might have been one to Max in his youth.

1395[[caption-width-right:342:[[CharacterCatchphrase GRRRRRREETINGS]]!]]
1396
1397An alien ConMan introduced in ''WesternAnimation/Ben10Omniverse''. Infamous but pretty harmless, Hokestar is constantly looking for a way to make profit through his inventions, usually with mixed results.
1398----
1399* CutLexLuthorACheck: Despite initially being a conman looking for a quick buck, he's actually pretty bright. He does eventually go straight and run a Mr. Smoothie (which he modified to travel to different dimensions) so a better use of his talents. He also makes a '''''smoothie'''-powered car'' which serves as another example of his talents.
1400* GadgeteerGenius: He builds a restaurant capable of going through ''different dimensions'' so he's brighter than he appears to be. Also makes a smoothie-powered car.
1401* LargeHam: Being a loud conman and with that catchphrase, no surprise.
1402* LovableRogue: His integrity hardly is higher than Argit, but he is pretty much harmless.
1403* MeaningfulName: Blarney sounds a bit like Barnum and is reminiscent of TheBarnum trope. Furthermore, the Hoke- from Hokestar seems to come from hokum, a word meaning nonsense.
1404* MultiArmedAndDangerous: Subverted; he does have multiple arms, but he could hardly be any less dangerous.
1405* SnakeOilSalesman: Its his schtick. Subverted as of "Store 23", he seems to be running his interdimensional Mr Smoothie as a legitimate business.

1411->Voiced by Creator/TaraPlatt
1412
1413A character introduced in ''WesternAnimation/Ben10Omniverse''. A hybrid of human and a species of RubberMan aliens known as the Kraaho that founded a village under Bellwood. Since Kraaho are from a volcanic planet, they were uncomfortable with Earth's climate, and attempted to use a nuclear device to change Earth's atmosphere and make it more appropriate for them. They didn't care what would happen to the everyone else. Ester disagreed and ended up helping Ben deal with them. By the end of the episode she was elected as their leader, thus ensuring they wouldn't try that again.
1414----
1415* BettyAndVeronica: She's the Betty (a sweet, flirtatious NiceGirl who makes little secret of her affection for Ben) to Kai's Veronica (a headstrong and argumentative {{Tsundere}} who refuses to admit her feelings).
1416* ChallengingTheChief: This is how the Kraaho leader is elected but there doesn't have to be a formal challenge; Ester did so unintentionally. "The Kraaho Way is whatever you say it is."
1417* ClingyJealousGirl: In "Fight at the Museum", after meeting Kai. By the end though, in a twist of {{Irony}}, she's bonded with Kai to glare at Ben for ''not'' comforting Kai when she's crying, prompting ''her'' to wrap an arm around her instead.
1418* CuteMonsterGirl: She's significantly more humanoid and feminine in appearance than the other Kraaho, and shares a mutual attraction to Ben. Justified, since she is half-human herself.
1419%%* TheCutie
1420* GreenSkinnedSpaceBabe: Ester is Ben's first ''mutual'' alien LoveInterest. She also happens to look exactly like a human save for her light purple skin and her eyebrows.
1421* HalfHumanHybrid: While Ester's parents are never seen in person and only her dad is ever directly mentioned, it's basically all-but-explicitly stated that Ester's dad was an alien (he was the leader of the Kraaho before Seebik took over) and that her mother was a human.
1422* LoveInterest: To Ben, who she obviously has the hots for. "Rules of Engagement" reveals that Ben and Julie have broken up, leaving Ester as the most likely new love interest.
1423* NiceGirl: Genuinely kind and friendly, and spends her free time hanging out with a group of Kineceleran kids. She's also far more patient than almost any of Ben's other love interests when dealing with his more negative traits; unlike Attea, Looma, and Kai, she likes Ben for ''him'' and isn't just interested in one of his alien forms.
1424* ObliviouslyEvil: She brushes off stealing a nuclear fusion engine for her people, as they need it to survive and she was genuinely unaware of what their real plans were for it. When she does learn their intentions, she's [[MyGodWhatHaveIDone horrified]].
1425* OfficialCouple: Played with; it's confirmed they have been on dates at least twice, and it is clear Ester considers their relationship as such. Ben, however, is shown to be almost completely oblivious to any form of romantic advances Ester tries. [[spoiler:In "The Most Dangerous Game Show", she does realize that Ben will end up with Kai and ends up with ''Antonio'' (Sunny's boyfriend, apparently broken up) of all people.]]
1426* ReplacementGoldfish: She replaces Julie as Ben's LoveInterest, though unlike Julie, they aren't explicitly stated to be in a relationship; "Return to Forever" and "Catfight" confirm they do go to watch movies together, but Ben [[SheIsNotMyGirlfriend constantly refuses to acknowledge they are more than friends]] and [[ObliviousToLove any advance she tries goes completely unnoticed]].
1427* RomanticFalseLead: [[spoiler:In the future, Ben ends up married to Kai. Having Spanner blurt this out was awkward, to say the least.]]
1428* RoseHairedSweetie: Her pink hair matches her sweet, affectionate personality.
1429* RubberMan: As a Kraaho, she has the power to stretch her limbs across great distances.
1430* SatelliteLoveInterest: Much like Julie, she has no major role beyond being Ben’s girlfriend; her one storyline is solved right in her first episode, and she never appears after that outside of episodes about Ben's love life.
1431* ShipSinking: [[spoiler:Ben ends up with Kai, and in "Most Dangerous Game Show", it's revealed that Ester is now dating Sunny's ex-boyfriend, Antonio.]]
1432* SuperpowerLottery: Full-blooded Kraaho require constant high temperatures to survive, such that they are living deep underground near a thermal vent and still need cold weather gear. Half-blooded Ester can move around the surface just fine with a warm jacket, and still has their RubberMan powers.
1433* TheWorfEffect: She effortlessly outmaneuvers Crashhopper (an alien who can jump at least 15 meters high) in her first appearance, but later episodes tone down her capabilities so the plot can advance, most notably when she is easily bested by Looma to show off how powerful and threatening she is.
1434* TomboyAndGirlyGirl: The Girly-Girl (affectionate, flirtatious, and romantic) to Kai's Tomboy (tough, headstrong, and aggressive).
1435* YouCantFightFate: [[spoiler:Her reason for breaking things off with Ben; she still likes him, but she knows that him and Kai are meant to be together.]]

1442->Voiced by Richard Doyle (''Ultimate Alien''), Creator/CoreyBurton (''Omniverse'')
1443
1444Ben's next-door neighbor, and the owner of a local grocery store in Bellwood.
1445----
1446* AscendedExtra: Appeared once in ''Ultimate Alien'', hiding aliens from the Forever Knights. He appears more often in ''Omniverse'' (though with a completely different look and attitude).
1447* ButtMonkey: When Pakmar isn't there to get his property damaged by Ben's DestructiveSavior tendencies, Baumann is the one who get it in the face.
1448* CharacterizationMarchesOn: He was friendly to Ben and his team in ''Ultimate Alien''. In ''Omniverse'', he's much more of a {{Jerkass}}, hating Ben for accidentally destroying his car and trashing his store while fighting aliens.
1449** Even his ''appearance'' has completely changed. When first introduced, he look like [[http://images2.wikia.nocookie.net/__cb20120604171110/ben10/images/7/78/Mr._Baumann_001.png this]]. ''Omniverse'' gives him the look shown on this page.
1450* CrankyNeighbor: ''Omniverse'' establishes Ben's been his neighbor since the latter was five years old, and with all of Ben's destructive habits, Mr. Baumann is none too happy about that fact.
1451* ADayInTheLimelight: "The Ballad of Mr Baumann" focuses on him and his relationship with his alien girlfriend Sheelane, whom he proposes to at the end of the episode.
1452* DisproportionateRetribution: Makes Ben pay off the damage to his car by doing deliveries, even though the damage was the result of an unprovoked alien attack.
1453* {{Expy}}: Of [[ComicStrip/DennisTheMenaceUS Mr. Wilson]], especially in the flashbacks with 5 1/2-year-old Ben.
1454* FourthDateMarriage: With Sheelane, technically third time they met and their second date. Though it is eleven years between meeting and getting married.
1455* FreudianExcuse: Mr. Baumann's Jerkass nature seems to be a result of being lonely. When it looked liked he was going to wish Ben would go away, he wished that Ben would be wrong about there not being a "Mrs. Baumann".
1456* {{Jerkass}}: Granted, Ben did wreck his car several times, but it always was an accident, and he apologized each time. However, a flashback involving the first time him and Ben met shows that he was never nice to Ben in the first place despite being a kid and most of the accidents being fairly harmless (seriously knocking over a stack of lima bean cans warrants a ledger?).
1457* JerkassWithAHeartOfGold: He's actually fonder of Ben than he lets on and he has served as something of an ally.
1458* InterspeciesRomance: "The Ballad of Mr. Baumann" reveals that he's been romantically involved with a mermaid-like alien named Sheelane since Ben was 5 years old.
1459* HappilyMarried: "The Ballad of Mr. Baumann" ends with him asking Sheelane to marry him. She accepts.
1460* MayDecemberRomance: Baumann looks to be in his 50's while Sheelane looks much younger, though she is an alien mermaid so who knows how old she actually is.
1461* OOCIsSeriousBusiness: In the WholeEpisodeFlashback "From Hedorium to Eternity", 11-year-old Ben, Gwen and Lucy try to warn Grandpa Max about the sudden strange behavior of the adults in Bellwood. Max initially dismisses it as their imaginations going wild, but once they describe how Mr. Baumann was acting strange, he changes his tune.
1462-->'''Lucy:''' But, Mr. Baumann was totally fine until he came back from the old Collins' house.\
1463'''Ben:''' Yeah, suddenly he was… nice.\
1464'''Gwen:''' To ''Ben''.\
1465'''Max:''' (''gasps'') Something's definitely wrong.
1466* PetTheDog: In ''Ultimate Alien'' he hides aliens from the Forever Knights. In "Frogs of War" [[spoiler:he hides the resistance in his basement]].
1467** He actually lets Ben do something for him at the end of "The Ballad of Mr. Baumann" at least somewhat recognizing that he means well.
1468* SameCharacterButDifferent: Apart from his name, Baumann in ''Omniverse'' looks and acts nothing like he was in ''Ultimate Alien''. It's to the point where in his debut, he claims to not have seen Ben since he was twelve years old, yet ''Omniverse'' establishes they've been neighbors for over a decade.
1469* SitcomArchNemesis: His feud with Ben is based purely on his petty grudge over Ben constantly (albeit accidentally) destroying his property. That said, they don't truly hate each other deep down and have even worked together when the time has called for it.
1470* ThePreciousPreciousCar: In addition to his actual car, he's very uptight about the condition of his store, even keeping a book that tracks down exactly the amount of property damage costs Ben owes him.
1471* ThrowTheDogABone: He gets to be involved with a hot alien mermaid woman "The Ballad of Mr. Baumann", fair payback for all the trouble Ben's put him through.
1472* TooDumbToLive: In "T.G.I.S.", he tries to prevent Ben from transforming and wrecking his store... while Dr Animo's minions are ''already'' wrecking his store, not to mention aggressing his customers.
1473%%* TookALevelInJerkass:
1474* UglyGuyHotWife: Baumann is an old, overweight, balding man, married to a pretty, young looking, mermaid girl. Lampshaded by 11-year-old Ben, who's more disturbed that said mermaid would find him attractive.
1475* UngratefulBastard: Admittedly, he has been dealing with Ben's destructive accidents for a very long time, but he never seems to care that Ben needs to ''protect'' others from dangerous alien threats, even if said protection often comes at the cost of his property.

1484
1485An alien trader working in Bellwood who regularly becomes a victim of Ben's clumsiness.
1486----
1487* ButtMonkey: When Baumann isn't there to fill the role. [[RunningGag Meaning quite often]].
1488* TheChewToy: Every time he shows up, something bad happens to his things
1489* EvilCounterpart: Mad Pakmar, Mad Ben's Pakmar, who thanks to Ben owns the only source of water and lords it over the slaves. Ben of course ruins that.
1490* HairTriggerTemper: Though in his defense, anyone would have this in his situation.
1491* HateSink: As the series progresses, Pakmar has become such a spiteful prick who only cares about the safety of his business and not any other priorities, even those that mean the welfare of the universe. In fact, he causes more harm just by obstructing Ben.
1492* {{Jerkass}}: Definitely. He always acts mean towards Ben every time he sets foot in his store. His counterpart in Mad Ben's world however, is an even bigger jerk, taking water and throwing it away right in front of dehydrated prisoners. Ben is happy he finally gets to knock down Pakmar, even if he isn't the same one from his world.
1493* JerkassHasAPoint: He has the right to be angry at Ben for (accidentally) wrecking his store many times.
1494* LaserGuidedKarma: Mad Pakmar's water business gets destroyed thanks to Ben and Ben 23, and said water is distributed to the people he'd been profiting from.
1495* LongList: He produces a list of property damages that is at least ten feet long when bringing his grievances to Max Tennyson.
1496* OhCrap: His reaction practically every time Ben shows up. Biggest example being in "Showdown, Part 1":
1497-->'''Pakmar''': (recognizes Ben as Heatblast) Ben Tennyson?! [[BigNo NOOOOOOOOOOOOOOO!]] (tries to run away)
1498* ManekiNeko: After one of Ben's fights destroy his pet store in the "Of Predators and Prey: Part 1" episode, he scrambles to save his last intact possession, a one-eyed maneki neko. It then gets smashed when Ben uses [[PileBunker Armodrillo]] to dig a hole in his China store in the "Ben Again" episode.
1499* MassiveNumberedSiblings: He has ''hundreds'' of children.
1500* NewJobAsThePlotDemands: Each time he appears, he has a new business. Justified because Ben keeps ruining the last one.
1501* ProperlyParanoid: He automatically assumes Ben will damage his property in some manner, and Ben never disappoints.
1502* SpitefulSpit: Occasionally spits on the ground while talking to Ben. He does not like the kid.
1503* ThirdPersonPerson: Presumably to make it clear English isn't his first language.
1504* UnluckyExtra: He has few to no relation to the plot of any episode he appears; most of the time he only is there to get his property accidentally damaged by Ben and remind us how clumsy Ben can be.

1510[[caption-width-right:300:''Wildvine if he was a hippie.'']]
1511->Voiced by Creator/EricBauza
1512
1513Pax is a Florauna (Wildvine's species), and an alien rights activist. He acts and dresses like a [[NewAgeRetroHippie stereotypical hippie]].
1514----
1515* AnimalWrongsGroup: He claims to an alien rights activist and member of Extraterrestrials for the Ethical Treatment of Aliens. Though his methods are non-violent, they are very misguided, as he is willing to free even extremely dangerous creatures from containment and has no concern for who gets hurt by them in the process.
1516* ChuckCunninghamSyndrome: He seems to have completely disappeared from ''Omniverse'' after "Rad".
1517* GoodThingYouCanHeal: He's graphically blown up twice and gets his head bitten off once, but it's alright because he's just a plant creature, and he regenerates.
1518* HealingFactor: Pax gets blown up twice and has his head bitten off, but he can regenerate and just keeps going on as if nothing happened.
1519* {{Hypocrite}}: Rook calls him out in his second appearance, he's concerned for the safety of the creature, but cares not for the other people in the ship who could be killed. He states that Pax put's the freedom of the creature over their freedom, when he's supposed to be fighting for everyone's rights. Pax didn't hear any of it because he was cleaning his ear(?), and wasn't paying attention.
1520* KnightTemplar: Wants to release dangerous and potentially deadly creatures at the cost of everyone's safety, believing he's doing the right thing, Ben states that's what makes him more dangerous.
1521* MeaningfulName: His name means "peace" in Latin.
1522* MySpeciesDothProtestTooMuch: Florauna are generally hostile and savage-like towards others, at least back in the Original series. However, Pax is a pacifist who acts and dresses like a hippie.
1523* PurelyAestheticGlasses: He wears a pair of red[=/=]blue colored specs, despite the fact that he's not nearsighted and a set with two lenses would be useless to a cyclopean alien like him.
1524* SitcomArchNemesis: He is this to Rook and despite Rook's straight-laced and patient nature, it's surprising how quickly Pax can annoy Rook.
1525* TooDumbToLive: Has twice freed highly dangerous aliens that would either have destroyed the planet or torn him apart and then had the nerve to try and stop people from putting them back, or trying to free them again after they have been secured for everyone's safety. One alien he set free turns monstrous when exposed to nitrogen, which he reasoned wouldn't happen since humans breathe oxygen, never considering that the atmosphere might have both.
1526* TookALevelInJerkass: Freeing the Screegit in his first appearance was an honest mistake, as he never thought to ask whether Earth's atmosphere had anything other than oxygen, but his second appearance has him freeing a Gracklflint which was both needed to save Plumbers stranded on a toxic planet and hostile to anything that wasn't its own kind.

1542* {{Jerkass}}: Rook Da, at first.
1543* NamedAfterSomebodyFamous: Rook Ben named himself after Ben.
1544* NoNameGiven: Rook Ben was previously simply known as "Young One", because he had not gone through his naming yet.
1545* TookALevelInKindness: Rook Da eventually comes to accept his son's choice of becoming a Plumber, allows his daughter to become one as well and even stands up to Kundo when the old master tries to stop them, getting hurt in the process. A stark change from his attitude in earlier episodes.

1557* HeelFaceTurn: Once Khyber's pet who fights Ben. After she becomes Kevin's pet, she's a recurring ally.
1558* LoyalAnimalCompanion: Was this to Khyber, or so it seemed; she obeyed the sound of Khyber whistling, which Azmuth managed to use to turn her against him. Played straight after she becomes Kevin's pet.
1559* NoNameGiven: Her name was not revealed until the credits of "The Frogs of War". Khyber only saw her as a hunting tool, and didn't care about her enough to name her. She is finally referred to by name in "For a Few Brains More".
1560* SamusIsAGirl: Prior to the reveal, everyone assumed that she was a male, even Khyber himself. Kevin corrects Khyber on this in "For a Few Brains More".
1561--> '''Khyber''': If you feed him, you'll dull his hunting instinct.
1562--> '''Kevin''': Zed's a ''girl'', you jerk!
1563* SatelliteCharacter: Justified, as she's a non-sapient pet.

1572Full name: Rad Profit Danger Trouble Dudesman. A mercenary and intergalactic smuggler, who will take on any job and transport any cargo so long as he's paid well.
1573----
1574* AntiHero: Being a mercenary and smuggler, he'll work for anyone who pays him well enough.
1575* CoolShip: The Lovely Duck.
1576* DisproportionateRetribution: Not talking to Ben, throwing Ben out the airlock, punching Ben in the face, all over Ben breaking a part and later using his ship to save his ass.
1577* EarlyBirdCameo: Literally. He made a cameo in "Have I Got A Deal For You" before properly debuting in "Rad".
1578* ExpectingSomeoneTaller: When he's introduced to Ben, he says that he thought Ben would be taller. It's funny because Ben was Diamondhead at the time, and even in his human form, he's still much taller than Rad.
1579* FunnyAnimal: Aside from flying in "The Vampire Strikes Back", he doesn't really do anything duck-like.
1580* GatlingGood: Pulls out some arm-mounted gatling lasers in "Rad Monster Party".
1581* KillerRabbit: You think that small duck-like alien isn't dangerous? Think again, there's a reason he's considered one of the best at his job.
1582* MetaphorIsMyMiddleName: In "Rad", he first claims that his middle name is trouble, then danger, then profit. Ben naturally doesn't buy it, and until Rook looks up some information on him, revealing that his full name really is "Captain Rad Profit Danger Trouble Dudesman".
1583* OnlyInItForTheMoney: Rook tried appealing to his conscience, which didn't work. Then he threatened not to pay him, which did.
1584* OverlyLongName: "Captain Rad Profit Danger Trouble Dudesman" is his full name.
1585* TookALevelInJerkass: In his first appearance, he already acted trigger-happy and hot-blooded, but was otherwise fairly easygoing and cool to get along with. During the Galactic Monsters arc however, he became cold-hearted and uncaring, just because Ben fouled up once. When Ben had practical concerns like incomplete repairs or an Omnitrix that won't work without being within collection range of a new DNA sample, Rad doesn't care BS about it. Furthermore, he even cuts off Scout while he was thanking them on radio. Mind you he ''always'' had a mean streak (in his first appearance he pointed a blaster at Ben for stopping him from shooting the Grackleflint), [[{{Flanderization}} but it wasn't always his main character trait.]]
1586* UngratefulBastard: After Ben saved everyone from Transyl's control, Rad punched him in the face ([[DisproportionateRetribution because Ben had used The Lovely Duck to smash into Zs'Skayr's castle]]).
1587* TheUnintelligible: His ship's AI, Pyxi, who can only be understood by Rad himself, and Grey Matter.
1588* TokenEvilTeammate: He'll help the heroes when they need him, but he doesn't care for anyone but himself or money.

1612-> Voiced by Creator/DavidKaye
1613
1614Skurd is a Slimebiote, a DNA parasite who can absorb and use the powers of his host. Though he initially works with Khyber, he abandons him in favor of the superior power of Ben and his Omnitrix.
1615----
1616* ArmCannon: He manifests powers by either growing an extra arm or forming one from another alien form over an existing one.
1617* ClingyMacGuffin: He boasts of being impossible to remove unless he wishes to leave. This is eventually proven wrong as he can be removed through ionic surgery.
1618* DeadpanSnarker: Snipes frequently with Ben.
1619* EleventhHourRanger: He's introduced at the beginning of ''Omniverse's'' eighth and final arc.
1620* EquippableAlly: His usual method of helping in a fight is to make a weapon from one of Ben's aliens; using Diamondhead to make a {{BFS}}, building an ArmCannon out of Bloxx, and so on.
1621* TheFogOfAges: [[spoiler:After billions of years, he (And the rest of his species) simply forgot what they existed for.]]
1622* FusionDance: Of the composite type; on his own initiative he can [[MixAndMatchCritters mix and match]] the limbs of Ben's alien forms.
1623* GentlemanSnarker: He speaks in a very classy manner and tone.
1624* InfinityPlusOneSword: [[spoiler:He finds out about Alien X's DNA being in the Omnitrix and forms a blade out of Celestialsapien matter (possibly even using Chromastone's crystals as basis) so Ben can break the Contumelia's barrier and stop Maltruant's plans.]]
1625* KidAppealCharacter: WordOfGod is that [[http://ask.fm/DerrickJWyatt/answer/121229959796 he was added to the show at the request of Bandai]], presumably to promote toys/merchandise.
1626* LastOfHisKind: Possibly; Azmuth says that his species is thought to be extinct. ''He'' certainly thought he was the only one. [[spoiler:While we do find out the origin and purpose of his race, we don't know if there are any left in the present day. Skurd ends up joining his fellow Slimebiotes in seeding the universe when he, Ben and Rook travel to pre-creation to stop Maltruant. It's implied this is a StableTimeLoop.]]
1627* MakeMeWannaShout: An Echo-Echo megaphone.
1628* MegaMicrobes: Is single-celled despite being about the size of a golfball; unless he has a host he cannot survive teleportation.
1629* OnlyInItForTheMoney: Or DNA; he loves sampling DNA, and agreed to work with Khyber because the Nemetrix provided such a wide array of it as well as an offer of profit from his hunts. As soon as he learned Ben's Omnitrix had an even greater selection, he promptly abandoned Khyber.
1630* {{Panspermia}}: [[spoiler:The entire purpose of his race, the Slimebiotes, is pretty much this and may have even designed as such. Their job is to gather, collect and deposit DNA in brand-new universes, resulting in the development of life in the new universe.]]
1631* PowerCopying: He can copy the DNA of anything he comes into contact with and replicate it on demand, usually producing extra limbs to defend himself. Being attached to the Omnitrix gives him access to Ben's entire arsenal of alien powers.
1632* PuppeteerParasite: Has some degree of control over his host's movements, just enough to jerk them around.
1633** Also when Ben needed to talk in Spanish, rather than translating, he made him talk in random Spanish words for ForTheLulz.
1634* StableTimeLoop: [[spoiler:Potentially. After he, Ben and Rook stop Maltruant, we discover his species' origin and he ends up joining them in seeding Ben's universe at its inception. Given how its said that he forgot his purpose after billions of years, it's implied that this is one massive cycle. He will seed the universe, forget what he is meant to do, join up with Ben, stop Maltruant and repeat the cycle. Given how it ties into stopping Maltruant, it's possible.]]
1635* TheSymbiote: Of the Mutualism variety.
1636* TeethClenchedTeamwork: Ben doesn't particularly like Skurd, but there's no way to get him off, and he is rather useful, so he's stuck with him.
1637** Reached its climax in "Malgax Attacks" where Ben finally gets Skurd off with Azmuth's help. However, Vilgax attacks using Malware's remains as an exosuit and being strong enough to defeat ''Atomix''. Ben realizes he needs Skurd and asks him to join up again, admitting they make a good team.
1638* TimeAbyss: Apparently [[OlderThanTheyLook billions of years old]] [[spoiler:as literally the first species in the universe. In that time he and his people have all but forgotten their initial purpose. Heck, Skurd even believed he was the LastOfHisKind]].
1639* TimeyWimeyBall: [[spoiler:He is brought to the creation of the universe to be accepted into an empty slot where he is reintroduced to it as a part of the initial life-seeding process. It's unknown is this is a time loop and he simply forgets in the interim.]]
1640* TookALevelInKindness: He develops a conscience having fought alongside Ben, best seen when he calls out Malgax (Vilgax with Malware's remains) after he and Ben stop him.
1641* VineTentacles: He can use Wildvine's DNA to create thorny vine whips for Ben.

1698* BrattyHalfPint: He's only six, but is ''very'' temperamental and heaven help you if you get him too riled.
1699%% Doesn't explain what the reation is. * BerserkButton: Do NOT call him annoying or act like a jerk to use him. Ben got to experience it whenever he lost patience or threatened to end his friendship with Simon.
1700* ChildProdigy: Downplayed. He knows a lot of interesting trivia and is able to use his mech suit pretty easily.
1701* ItsAllAboutMe: As he puts it, he's annoyed adults telling him what to do despite a lot of his complaints being childish (Eating certain foods, not to annoy people, etc). Justified as he's still very young and doesn't know much better.
1702* MirrorCharacter: With Ben, the two tend to be annoying to their more mature family (cousin and brother respectively) and they do bond a bit over it. This thing though is that Simon is still young and not mature enough yet to realize that his actions can tend to annoy others. Also doesn't help that he can be hard to talk down once he's angered.
1703* MotorMouth: Talks a mile a minute, of course he is just a young kid, but still.
1704* PintSizedPowerhouse: Again six, but has the power of a mech on his side and no qualms using it to get his way.
1705* PunnyName: Simon Sez, "Simon Says", har har.
1706* RocketPunch: Can fire rockets out as projectiles.
1707* ShadowArchetype: Basically Ben if he didn't have restraint in using his power as he tend to cause ''a lot'' of damage once he's in the mech with little regard for others wellfare. [[spoiler:The Forever Knight recruits him for this exact reason.]]
1708* SpoiledBrat: Pretty obvious Maxine dotes on him too much as a lot of the problems when he's involved are always due to him throwing a tantrum.
1709%%* TransformingMecha: Can summon one from his backpack.
1710* TheUnreveal: There's virtually ''no'' explanation how he got his mech, it's just treated as a normal thing in the series. All that is known about it is that Billy Billions owned the factory that created the model of his mech suit. Which also means Billy can take control over the armor at times and make Simon do his bidding (though it never lasts since Simon is still the one piloting it).

1717* AloofBigBrother: To Simon. Even when Simon's rampaging around in his mech, this hardly phases him and he seems more annoyed whenever it happens.
1718* JerkWithAHeartOfGold: As aloof and antisocial he can be, he helps Ben handling Simon and even plays video games with him, smiling for the first (and this far only) time in the series. He also does end up acknowledging Gwen when they're stuck in traffic (albeit as they're about to leave, causing her more annoyance than joy).
1719* LoveInterest: For Gwen, though one sided on her end.
1720* MoralityPet: To Simon. A few words from him and Simon stops causing trouble. Like Gwen with Ben, he knows how to handle his little brother's tantrums.
1721* ObliviousToLove: Gwen is infatuated with him, but Ryan doesn't even bat an eye to her advances.
1722* PhoneaholicTeenager: A good chunk of the time, most of his appearances will just be him checking his cell phone.
1723* TheStoic: Anti-social to a fault and rarely without a bored expression on his face.

1732 [[caption-width-right:350:After merging with the Rustbuggy.]]
1733He once was [[spoiler:Upgrade]], before the fight with Vilgax in "Omni-Tricked" almost destroyed him, forcing him to fuse with [[spoiler:Ben's DNA]]. Since then he became the GeniusLoci of [[spoiler:Omnitrix]], until he escaped in "Innervasion" and joined [[spoiler:Team Tennyson]].
1734----
1735* BrutalHonesty: He dislikes Vilgax, but had to agree that Ben is "kinda useless" without his alien forms, mostly due to Ben's cockiness carrying over to him.
1736* CoolCar: He transformed the Tennyson Go-Kart in one [[spoiler:by merging with it]].
1737* EmpathicShapeshifter: Fused with the Rustbuggy he changes to match the Omnitrix or Antitrix alien driving him.
1738* GeniusLoci: Being a {{Technopath}}. He has a large control of [[spoiler:the Omnitrix]], even modifying its structure to fight off intruders [[spoiler:like the Fulminis]].
1739* HalfHumanHybrid: His DNA is a mix of a [[spoiler:Galvanic Mechamorph]] and a human [[spoiler:(Ben)]].
1740* HappilyAdopted: [[spoiler:Grandpa Max]] immediately declared him a new member of their family.
1741* HeroicSacrifice: [[spoiler:Barely subverted]]. ''Twice''.
1742* IKnowYoureInThereSomewhereFight: To Ben [[spoiler:when the High Override put Shock Rock under his control]].
1743* MrExposition: He is the one who explained how [[spoiler:the Fulminis]] were able to use Shock Rock and the Omni-Enhanced forms to [[spoiler:open a gateway to invade Earth]], as well as how to stop it.[[spoiler:He also explained to Gwen and Max how to access the alien forms]].
1744* PaletteSwap: Looks exactly like [[spoiler:Ben, only with Upgrade's color scheme]].
1745* SixthRanger: Joined the [[spoiler:Tennyson family]] at the end of Season 2.
1746* SuspiciouslySimilarSubstitute: After Ben lost [[spoiler:Upgrade in the season 1 finale, here comes a new {{Technopath}} to make up for it]]. Of course, it's actually a weird subversion, since [[spoiler:he '''was''' Upgrade, and Ben can't transform into him. He is actually out of the Omnitrix now, acting as a SixthRanger]].
1747* {{Technopath}}: Just like when he was [[spoiler:Upgrade]].
1748* WalkingSpoiler: The way he was created and his role in the season 2 finale are a pretty big plot point.

1753-->'''Voiced by:''' Creator/DavidSobolov
1754An associate of Lagrange who cares about family.
1755----
1756* AffablyEvil: While he associates with Lagrange [[spoiler: and later Forever Knight]], he’s still a very personable guy.
1757* CoolCar: Uses a souped-up car for illegal racing, complete with a "family" button on the dashboard.
1758* {{Expy}}: Of Creator/VinDiesel, particularly his role in Franchise/TheFastAndTheFurious series.
1759* HeelFaceTurn: [[spoiler: Joins the Tennyson family as an HonoraryUncle in the Season 3 finale]].
1760* PunchClockVillain: Is part of Lagrange’s crew, but isn’t malicious about it.
