Western Animation: Ben 10: Omniverse
The fourth iteration of the Ben 10
franchise following Ultimate Alien
One year has passed since the events of Ultimate Alien
. Earth has eventually been declared a free system, and the aliens now live freely amongst humans
. Ben, now equipped with his new Omnitrix, is still working for the Plumbers. Eventually, Gwen decides to leave Belwood to go to college, and Kevin follows her. With Ben now alone, Max assigned him a new partner, a young Badass Normal
alien plumber named Rook
(much to Ben's dismay
). As Ben must learn to cooperate with Rook, he has to face the arrival of Khyber, a mysterious alien hunter who set his sights on him
Intended to conciliate the style of the original Ben 10
series with its two sequels, the series toned down the Darker and Edgier
approach introduced in Ben 10: Alien Force
and goes for a entirely new, very simplified art style designed by Derrick J. Wyatt (Transformers Animated
, Scooby-Doo! Mystery Incorporated
...) and Denser and Wackier
tone, and massive references and homages to the original show
, such as bringing back several old aliens, redesigning the main characters so they would look closer to their original counterpart, and multiple Continuity Nods
and Mythology Gags
. Though for all the problems it intended to fix, Omniverse
only ended up breaking the base even more than it already was
Concerning the plot, the show takes advantage on the Time Skip
between the original series and Alien Force
, using it to introduce new adventures that took place in the original series' era when Ben was eleven years old. These are interleaved as flashbacks with the present-day plot, thus allowing not only to bring back the original series' incarnation of the character while keeping tracks of his teenage self, but also to create new villains, characters and events that have a connection to Ben's past
The Ben and Vilgax from this series are set to appear in the IDW Crisis Crossover
comic book event Cartoon Network Super Secret Crisis War
in June 2014.
The series concluded November 14, 2014 in burn-off form, and there are currently no plans to continue the Ben 10
franchise - making Omniverse
the final series in the Ben 10
franchise's nine-year run.
This show contains examples of:
open/close all folders
- Aborted Arc:
- The first story arc ended with The Reveal that Khyber actually was working for Malware and Psychobos, and was originally supposed to kidnap Ben so they would get the DNA from his Omnitrix to complete the Nemetrix. Come Outbreak, the Nemetrix develops a flaw out of nowhere, forcing Dr Psychobos to steal a piece of Galvan tech from the Omnitrix; he doesn't seize the opportunity to collect the DNA, and the Faction just moves to the next phase of their plan with the whole "collecting the Omnitrix's DNA" part never to be mentioned again.
- Joseph Chadwick is shown to have survived his experiences in "An American Benwolf in London", and most likely to continue his villainy. He, nor the Forever Knights, never appear in the series again afterward.
- Accidental Kiss: At the end of "The Most Dangerous Game Show," Ben slips on a Banana Peel and crashes into Kai, causing their lips to meet.
- Accidental Marriage: Thanks to Kevin's scheming, Ben became the fiance of a Tetramand warrior princess named Looma.
- Affably Evil: Yetta's first reaction upon seeing Ben Tennyson while being chased by Plumbers is to compliment him and take a selfie with him, all before fighting him.
- A Day in the Limelight: "The Ballad of Mr. Baumann" for the most part focuses on Mr. Baumann, and explains why he knew Ben could turn into aliens prior to the Time Skip, along with somewhat fleshing out his motivations.
- Aesop Amnesia: A lot of the things Ben had already learned in the previous sequels or the original show (teamwork, fighting without the Omnitrix, etc.) are totally ignored by this show so they can make new episodes about him learning them again.
- In Ben's first encounter with Hypnotick, he escapes from its Lotus-Eater Machine by remembering that being a hero is about helping people, not getting the adoration the illusion showed him. The next time Ben faces Hypnotick he falls for the hypnosis even more easily than the first time.
- An especially blatant case in episodes like Store 23, where Ben, when called out by Max for toying with the villains, answers by "They are bad I am good, the end!", before spending the rest of the episode learning an aesop about. This attitude from him can come up as very frustrating after the White and Grey Morality of Alien Force and the whole arc in Ultimate Alien that had Ben struggling to not become a Knight Templar.
- The citizens of Anur Transyl; In "Rad Monster Party", they call Ben a "monster", and hate him. They seem to change their minds after getting a lecture from Scout about how they shouldn't judge by appearances, but in the very next episode, they're back to hating him again.
- Alas, Poor Villain: Malware basically shapes up to this, leading to His Death. All Malware initially wanted was to be cured.
- Alien Lunch: It was hinted before that exposure to aliens had something to do with Grandpa Max's Lethal Chef tendencies, but it's made clear in this series that aliens love his cooking. He's only a Lethal Chef to humans.
- All Amazons Want Hercules: It's revealed that female Tetramands are traditionally stronger and better fighters than males, and that a female will only choose a male who can defeat her in combat to be her husband.
- All Girls Want Bad Boys: Lampshaded by 12-year-old Kevin in "From Hedorium to Eternity", when telling Cooper how he has no chance with Gwen.
- Alternate Universe: "Store 23" shows Ben finding himself in universe 23. This is a universe where Max dies before Ben ever found the Omnitrix, thus Ben 23 never gets the Character Development of the original Ben and nearly rips Azmuth in half because of it. Later it's revealed there are hundreds of alternate timelines and some of those Bens are evil, and at least two never get the Omnitrix. And somehow there is one where Argit has it.
- Amoral Attorney: "Universe vs. Tennyson" has Chadzmuth, the Galvan lawyer. He freely admits to being amoral, and abuses every loophole in existence to free his clients. In Ben's trial he has Ben turn into a Tetramand and invokes a special privilege Tetramand defendants have that allows them to challenge court verdicts through single combat with an opponent of the prosecution's choice. When Ben's Celestialsapien opponent proves to be too much, Chadzmuth points out that you only have to be a Tetramand to invoke the challenge, not to complete it, and Ben could turn into whatever form he needed.
- And I Must Scream: Lord Transyl's victims are fully aware of everything they do while Transyl is jerking them around like puppets, and while they can still speak, it seems to be about the limit of what they can do.
- And the Adventure Continues: The series ends this way with Ben and Rook, bored since the Maltruant incident and seeing the beginning of creation itself, decide to go explore the world with Gwen and Kevin.
- And Your Reward Is Clothes: Ben saves the universe from being annihilated with Alien X, but no one believes him. He does, however, get a shiny new hooded sweatshirt.
- Animal Wrongs Group: Pax is an animal rights activist who, on two separate occasions, unleashes creatures that are an inherent danger to other living beings and actually tries to prevent Ben from attempting to curb their destruction because it would require reimprisoning them.
- Animesque: Unlike the past seasons, Ben and the others are much more likely to have anime-style outtakes, such as the veined-forehead for stressed out.
- Apocalypse How:
- The Annihilarg in "So Long and Thanks for all the Smoothies" can cause a Class X-4. And actually does. Undone by Alien-X.
- In "And Then There Were None", Vilgax reveals that he has a Chronosapien time bomb that can destroy every single timeline except the one in which the Omnitrix never existed, causing a Class X-5. Time traveler Eon recognized the device, indicating that such devices are not unique, though he only expected it to destroy one timeline. Destroying all the timelines, except one is not something he saw coming. Also notable is that Atomic X was vulnerable to it, in contrast to Alien X's immunity to the Annihilarg.
- Appearance Is in the Eye of the Beholder: The Contemelia are fifth dimensional beings, whose true form cannot be comprehended by the minds of third dimensional beings. Instead, they appear to each being as who or what they hold dearest in their hearts; Ben sees a walking Mr Smoothy cup, Rook sees his father, and Maltruant sees himself. Skurd, on the other hand, simply sees them as masses of energy.
- Arc Number: In "Store 23", 23 was pointed out to be a reoccurring theme. Store 23 transported to a world with Ben 23, and the frequency of the interdimensional engine of 23.
- Arc Welding: In "Ken 10", Kevin 11,000 had a sleek, black outfit from his time in the Null Void. The Rooters are more or less shown to be the origin of this outfit. He also got his chin scar from Ben.
- Arson, Murder, and Jaywalking: Word of God is that Pax got arrested in "Have I Got A Deal For You" due to breaking and entering, Skreegit theft, interfering with Plumber business, and loitering.
- In "While You Were Away", Rook Shar wants Sheriff Watt-Senn to punish her brother Young One for reckless endangerment, crop destruction & being a brat.
- Art Evolution: The show's animation is simpler, but much more streamlined and fluid than each previous series.
- Art Shift: Much more noticeable than the Ben 10 to Alien Force shift. Take a look◊. Ben and the gang aren't the only affected ones. Spidermonkey has a new design as well here◊.
- Justified in-universe in "So Long, and Thanks for All the Smoothies" when Ben has to recreate the entire universe due to an alien doomsday device going off, and while everything looks the same, the classic Mr. Smoothy mascot now looks like more of a demented looking character.
- The Secret Saturdays get this treatment during their crossover episode. In fact, they look way different than their original looks.
- According to Chadzmuth, the Celestialsapiens are behind this and even references Azmuth's changes in appearance.
- Ascended Extra: Cousin Lucy. Appeared in one original series episode six year prior for about six seconds but returns as a focal character in "Mud Is Thicker Than Water".
- Asshole Victim: Master Kundo. Even Ben, Rook, and Rook's siblings barely seem to care that they (seemingly) accidentally killed him.
- Assimilation Backfire: In "Showdown Part 2", Malware manages to absorb Ben as Waybig into himself. Inside, Ben has a flashback and finally forgives himself for losing Feedback, resulting in him reobtaining and transforming into Feedback to escape from Malware from the inside. Malware was doubly surprised for Ben escaping and doing it as Feedback, the alien he had destroyed in the past.
- Asskicking Equals Authority: Ester is made leader of the Kraaho after beating their former leader, Seebik.
- As You Know: When he returns in "Mystery, Incorporeal", Darkstar tells Gwen about how Charmcaster banished him from Ledgerdomian, even though she was there and there's really no reason to.
- Author Appeal:
- Derrick J. Wyatt makes no secret of the fact Grey Matter is his favourite alien; not only does Grey Matter come back after being absent for the two previous sequels, but Azmuth and the Galvan have ended up as part of two different arcs. Blucik and Driba, two Galvan of questionable skill, are added as regular supporting characters.
- He also likes the Gourmands, and "Tummy Trouble" focuses on two particular tribes of them. Sludgepuppies have also had two episodes, one bringing back the one-shot cousin Lucy after six years.
- XLR8 also seems to get a fair amount of attention, after being replaced by the Suspiciously Similar Substitute Fasttrack in the previous series. Aside from getting back into Ben's roster, a small group of them (from little kids to teenagers) show up as background characters from time to time ("Hot Stretch" and "Collect This" being two examples).
- Awesome Mc Cool Name: Rad Dudesman. If that ain't enough, see Metaphor Is My Middle Name below.
- Badass Boast: Charmcaster, accidentally summoned by Ghostfreak, gives an impressive villainous introductory speech... which is instantly deflated when he deals with her by basically flicking a switch to send her back where she came from before she got around to actually attacking. She didn't take this lying down, however.
Charmcaster: I am Charmcaster, daughter of Spellbinder, conquerer of Adwaita, absolute ruler of Ledgerdomain, and I WILL NOT BE DENIED- *poof*
Ghostfreak: Back to work.
- Badass in Distress: Magister Patelliday, an old, apparently a bit senile Pisciss Volann Plumber and Barney Fife pastiche, gets captured by pirates as a plot-point for "Gone Fishing". While Ben, Rook and Max are trying to find and rescue him, Max assures them Patelliday can handle himself of his own. He does.
- Back from the Dead:
- "T.G.I.S.", the crossover episode with The Secret Saturdays sees that series's Big Bad, V.V. Argost resurrected by Dr. Animo.
- No Honor Among Bros includes an appearance by Slix Vigma. In his sole previous appearance he was Impaled with Extreme Prejudice by Kevin 11, seemingly killing him. Then his ship blew up with his body still on it. Ben seems unsurprised by his reappearance, being more taken aback that he has gone "mostly legit".
- Badass Normal: Rook, who despite being an alien relies on various technology and weaponry to fight. He blocks a laser with a spoon as an Offhand Backhand.
- Bad Bad Acting: Ben's actor is a parody of 90s animation tropes, so he has this in spades.
- The Bad Guy Wins:
- "Vilgax Must Croak" ends with Vilgax's escape after all the effort Ben and company went to keep him in Incarcecon.
- "Fight at The Museum" ends with the villain obtaining the device they were searching for all episode, the "key to time itself".
- Bare Your Midriff: K8-E, a female teenaged Kineceleran that appears in several episodes.
- Batman Cold Open: Twice in the same episode; the pilot starts with a scene of 10 years old Ben fighting against Malware (and winning); then, we get a scene of present Ben, Gwen and Kevin chasing Zombozo.
- Batman Gambit:
- Ben and Rook pulled one in "Of Predators and Prey" by faking an argument and letting Khyber kidnap Ben so they could better find him.
- Psyphon does it in "Outbreak" by tricking the Plumbers into shutting down the forcefield so he and his henchmen can escape.
- Kevin pulled one on Ben in "Many Happy Returns" to annul his engagement to Princess Looma by getting Ben engaged to her instead.
- Attea pulled one in "Frogs of War" to become the Incursean ruler by having Ben take down Emperor Milleous.
- Ben pulls one in "The Vengers", pretending to quit being a hero so the Vengers, no longer having a common foe to focus on, wind up fighting amongst themselves for all the fame and glory.
- Beam-O-War: In Showdown part 2, Malware vs Helix-powered Feedback. Feedback wins.
- Another happens in "Frogs of War" between Way Big's cosmic ray and the Incursean mothership's Wave Motion Gun. Way Big wins.
- Beard of Evil: Homaging the Star Trek Mirror Universe, evil AU Tetrax has a beard made of the same crystal as the rest of him. though it turns out he's not evil. Or at least, who he's working for isn't. He did cause a tremendous amount of property damage when we thought he was evil.
- Because Destiny Says So: Spanner presents this as an argument for why Ben and Kai should get together. In the future he's from, they're a happily married couple.
- Beethoven Was an Alien Spy: Dr. Jekyll was a Forever Knight researching an alien Super Serum.
- Prior to the Revolutionary War, George Washington was a Plumber.
- Berserker Tears: 11 years old Ben, of all people, has this when he almost kills Malware for destroying Feedback.
- Best Her to Bed Her: This is how Tetramand courtship works. It's an uphill battle for males since female Tetramands are usually stronger. Kevin went along with this in his more criminal youth to get ahold of an indestructible Tetramand engine block for his car. When his fiance Princess Looma goes to Earth to claim him as her husband, Kevin cons Ben into challenging her to a fight. Ben defeats her, but learns too late that this means he is Princess Looma's fiance now. During the fight, Looma's father fondly reminisces about his courtship battle with her mother.
- Beyond the Impossible: Ben's actor claims to have put on a show that drove Vulpimancers to tears.
Ben's actor: Vulpimancers. No eyes. To tears!
- Big Bad:
- Khyber appears to be this in the first arc, but it's really Malware and Psychobos sharing the role with him as their dragon.
- Malware in the second arc.
- The Inkursean Empire, particularly Milleus and Attea, in the third story arc.
- Albedo in the Duel of The Duplicates arc.
- Zs'Skayr and Lord Transyl in the Galactic Monsters arc.
- Proctor Servantis in the Rooters arc
- Mad Ben for the seventh arc, with Maltruant serving as the Bigger Bad.
- Maltruant for the "Time War" arc.
- Big Ball of Violence: Dr Animo gets into one with his future self in "Animo Crackers".
- Bilingual Bonus: In "Secret of Dos Santos," Skurd tampers with the Omnitrix, giving Rath clothes, and making him speak in Spanish. The first thing Rath says translates as "Pants!? Clothes!? These are the pants of a wrestler! Rath was tired of being naked! Thank you, little green booger monster!"
- Bizarre Alien Biology: The Galvan start out as tadpoles, and as "For A Few Brains More" reveals, they have a "pre-brain" that handles all their bodily functions.
- Revonnahganders are born with tails (that fall off at puberty). "No Honor Among Bros" reveals they have a "temperamental lobe" in their brains that govern their personalities.
- Bizarro Universe:
- Blank White Eyes: Ben, Gwen, Kevin, and Grandpa Max get them when Attea reveals her Batman Gambit.
- Blatant Lies: "The Omnitrix never fails".
- Book Ends: The final episode of the series, and at the moment the franchise, ends the same way the franchise began: with Ben preparing to go on a road trip.
- Borrowed Catchphrase: In "Fight At The Museum," Kai uses Ben's "It's hero time" catchphrase, after Ben (as Walkatrout) failed to break down a door.
Ben: Great. I've already been robbed of my dignity, and now you're stealing my catchphrase?!
- Brainwashed and Crazy:
- The population of Ravana. courtesy of Dr Psycobos and the Incurseans
- Rath is under Mind Control by Nyancy-Chan for most of "Catfight".
- Breaking the Fourth Wall: In "Clyde 5", Clyde and Ben argue during the intro sequence.
- Breather Episode: The third arc comes right after one of Ben's most personal enemies who spanned over two arcs, and the villains of the third arc are the Incurseans, who have much more comical moments, aren't really terribly threatening until the end, and even the actual Big Bad, Attea, is usually defeated due to a comical flaw being exploited.
- Briar Patching: Ben pleads with the Kraho not to release NRG from his suit. Naturally, they do, and NRG's true form stops the Kraho device singlehandedly.
- Brick Joke:
- In "The More Things Change Part 2", Ben accidentally takes out an underground bus driver's brakes due to being in front of it while he's NRG. Later on, Ben as Shocksquatch fights Khyber's pet in "Buglizard" form, with the bus coming again, and having Khyber's pet be run over by it, remembering the car's lack of brakes.
- There's another one in "Special Delivery": A flashback shows young Ben (As Way Big) throwing Mr. Baumann's truck into orbit. In the present, Ben unknowingly knocks it out of orbit after throwing Sunder's jet glider. The truck comes down on Baumann's house a few hours later.
- And in "Ben Again", Paradox mentions something about a Time War to past Ben. Come the very end of the episode, Ben 10,000 appears asking where Paradox is at because he's needed for the Time War.
- Broad Strokes: Word of God states that certain elements from previous series will be ignored in favor of a cleaner narrative.
- Broken Aesop:
- When confronted with Dr Psychobos' Fantastic Racism, Azmuth's reaction was to state that trying to prove which one of their two species was the smartest was a waste of time, energy and resources. This seems like a pretty honorable opinion to stand for, but later episodes have Blucik and Driba mock Psychobos by claiming that "The dumbest Galvan is smarter than a Cerebrocrustacean". Nothing seems to contradict them and, to make things worse, Word of God implied that they were right.
- Also, in "Rad Monster Party", the inhabitants of Anur Transyl are beings based on horror-themed monsters, but Ben does not consider what outsiders are to them. The moral of the episode is that you should not judge people based on stereotypes, and about placing oneself in their shoes. In the end, Ben clearly did not learn anything.
- Granted, Ben enjoyed his time on the world and had nothing against the people before being ostracized and to be fair, the fact that all of the inhabitants resemble famous monsters raises some questions.
- "Catfight" ends with Ben explaining to Looma and Attea that they're both strong, capable leaders on their own, and don't need a "trophy guy" to gain respect. That coming from a show which portrays all its female characters as either villainesses or love interests.
- In "And Then There Were None", Ben tells his alternate self that the Omnitrix is not necessary to be a hero. All of the alternate Ben's accomplishments in the next episode depend on his use of the Omnitrix.
- To be fair, Ben also said the Omnitrix was "just a gadget", and it was how the alternate Ben used it that mattered.
- The Bus Came Back:
- After two series of absence, Phil, Max's old Plumber partner, finally returns, as a test subject for the Nemetrix.
- Also, Gwen and Kevin drop by for big arc-enders.
- Six-Six made his reappearance alongside his other family members in "Vilgax Must Croak".
- Ghostfreak/Zs'Skayr is apparently going to make his return, after Alien Force gave him a one-off appearance.
- The Circus Freak Trio (Last seen in the original series' finale) return in "Something Zombozo This Way Comes", working for their old boss, Zombozo, for the first time since their debut appearance.
- In "Animo Crackers", Ben calls Lieutenant Steel, who, like many other characters, hasn't been seen since the first series. He even lampshades this, saying that Ben never called him up until now.
- In "And Then There Were None", Gwen 10 appears for the first time since her single non-canon appearance back in the original series' second season.
- In "And Then There Was Ben", Ben 10,000's son Kenny (last seen in the non-canon original series episode "Ken 10") makes a brief cameo.
- "No Honor Among Bros" features Slix Vigma, from the original series episode "Grudge Match", as the host of the Golden Fist Tournament.
- During the Rooters arc, the Plumbers' Kids return; Helen and Manny had last appeared in Alien Force, and Alan last appeared in Ultimate Alien. note
- In "Clyde 5", Aunt Vera (from the original series episode "Early Retirement") returns.
- "The Color of Monkey" saw the return of one-off villain Jarret, king of the Phantophage from the Alien Force episode "The Con of Rath" note .
- Bus Full of Innocents: In "Malefactor", Malware sets an oil tanker on course for a school bus as a Sadistic Choice for Ben: stop him or save the bus. Naturally, Ben does the latter.
- Butt Monkey:
- Ben is back on being that.
- There's also Pakmar, an alien merchant whose places of business have been destroyed on three separate occasions (The last two times solely due to Ben's presence).
- Similarly, Mr. Baumann, whose store and car usually suffer as a result of Ben's antics.
- Bystander Syndrome: Azmuth dismisses the fact that young Ben is mode-locked into alien form as secondary to his current task, until Ben starts breaking his stuff while looking around. Then he takes a few seconds to deal with it.
- Ben, of all people (as well as Rook, Rad and Hobble, though for Rad it does make sense) is subject to this in the Galactic Monster story arc, in stark contrast with his usual behavior. During his time on Anur Transyl, he is very well-aware Zs'Skayr is scheming in the dark, yet focuses only on what he initially came from and makes no effort to track him down or foil his scheme, unless events gets to him by themselves. By the end of the story arc, he was going to leave the planet with Zs'Skayr still undefeated, and went back only so he could acquire Lord Transyl's DNA.
- Early Installment Weirdness: In the first episode, Khyber whistles with his lips instead of his neck-holes, Rook uses contractions (though is still quite formal), and Pakmar isn't a Third-Person Person.
- The first two episodes have slightly more in common with the two previous series, albeit lighter, is paced somewhat differently than most later episodes, and even seems slightly more moderated in its silliness. This likely has to do with the fact that the script was penned by the late Dwayne Mc Duffie.
- Easily Forgiven: The Kraahos get away with their quite dangerous actions with only having Esther as their leader as punishment. Even after that, a few are still sneaking around committing crimes.
- Emo Teen: One of the alternate universe Bens.
- Emotion Eater: Charles Zenith in "Most Dangerous Game Show" is an alien that feeds on drama.
- Epic Fail: Ben learns the hard way that LEGO does not make a good net.
- Establishing Character Moment: Rook's introduction has him take out three alien criminals, showcasing that he's very effective, but the scene afterward showcases his social awkwardness (in that he tends to take things very literally, and not being able to understand sarcasm).
- Everything's Better with Princesses: Subverted with Princess Attea and Princess Looma Red Wind.
- Evil Counterpart: Khyber has shades of this; he uses a device similar to the Omnitrix to turn his pet into various predator monsters.
- In "Store 23", Tetrax and Azmuth are both villains that Ben 23 battle. Subverted when Ben 23 finds out that they aren't evil and just wanted the Omnitrix back since Ben 23 wasn't using it responsibly. Tetrax-23 is shown to be more anti-heroic than his main dimension counterpart though. Also with them is Sevenseven's good counterpart.
- Evil Is Cool: In-universe: Ben comments that Pyronite Psyphon looks "kinda cool."
- Evil Sounds Deep: See Power Echoes below.
- Expendable Alternate Universe: In "And Then There Were None", Vilgax and Eon recruit a group of Ben Tennyson's from various alternate universes and brainwash them into being loyal minions. These include a dark-haired Ben, spiky Australian Ben, zombie Ben, and Albedo. Professor Paradox counters by recruiting Ben 23, Ben 10,000, and Gwen 10. This trope is zigzagged, as every last one of them end up being killed by a temporal bomb designed to wipe out alternate timelines, leaving only a timeline where there is no Omnitrix.
- Expository Theme Tune: The theme song explains the franchise's entire premise of Voluntary Shapeshifting Henshin Kid Hero Ben saving the world from the forces of evil.
- Expy: The Thep Kufan and Loboan that Zs'Skayr recruited in the first series don't return in this series, but Kuphulu and Crüjo seem to be meant to be close analogues to them, albeit voiced.
- Eye Scream:
- When Eyeguy was used to try to subdue the Grackleflint, the creature spat into his many eyes.
- In "Blukic and Driba Go To Area 51," Ben accidentally becomes Whampire in the daytime. We are then treated to a close-up of his eyes bubbling in the heat.
- Facepalm: In "It's a Mad Ben World Part II", Ben 23 causes Ben to facepalm as Gravattack, which hits the omnitrix symbol on his forehead, which causes Ben 23 to untransform, because commands from each of their watches are going to the other Ben's omnitrix.
- Fake Defector: Kevin pretends to rejoin the Rooters in the "Weapon XI" two-parter.
- False Memory: Proctor Servantis implanted these into the minds of Kevin, Argit, the "Plumbers' kids", and Max.
- Fantastic Slur:
- In "Hot Stretch", Seebik refers to non-Kraaho lifeforms as "cold cuts" (Kraahos being creatures who require vast amounts of heat to be comfortable).
- According to Defis Vivlepister (the Sludgepuppy who plays Ben in his intergalactic TV show), Sludgepuppy is an offensive slur, though none of the Sludgepuppies seen before had any problem with being called it.
- Fastball Special: Ben and Kevin utilize this when chasing Zombozo.
- Felony Misdemeanor: The Tetramands have a very dim view towards lawbreakers. Outside one of their auto shows are several folks buried up to their necks in sand, one of whom was being punished for jumping the turnstile.
- A Form You Are Comfortable With: The Contemelia are fifth-dimensional energy beings which appear to third-dimension beings in whatever form holds the most sway over their hearts (Rook sees his father, Ben sees Mr. Smoothie, and Maltruant sees himself). Skurd, however, is able to perceive them in their true forms as masses of energy.
- Friendly Rivalry: Max has one with Sheriff Wat-Senn.
- Five Rounds Rapid: The Plumbers continually fire at the zombie clowns in "Zombozo This Way Comes", even though it has no effect and isn't even slowing them down.
- Combined with Took a Level in Jerkass when it come to 10 years old Ben. While he always was immature and obnoxious in the original show, his Omniverse portrayal takes it Up to Eleven. He actually succeeds in being worse than 15 years old Ben was in season 3 of Alien Force.
- To an extent, 16 years old Ben is portrayed as much more bumbling, immature and clumsy than he was in the two previous sequels, and has big moments of Jerkasserie as well; exemples include taking credit for Rook's idea in front of Max in Predators and Prey, accidentally breaking up with Julie over a misunderstanding that was caused by his stupidity or failing to recognize the treath Vilgax represented (the latter, especially, contracticts his attitude in the finale of Ultimate Alien). This was toned down a bit toward the end of the second story arc, only to have him flanderized again in the third story arc. There is even flanderization of his flanderization: in season 3 of Alien Force and Ultimate Alien, Ben had taken the habit to constantly (and annoyingly) remind everybody he had saved the entire Universe during the Hightbreed war. Now, he constantly reminds people he "Saved the Universe a billion times".
- The Omnitrix itself was flanderized: its tendencies to give Ben the wrong alien are raised to such a level that it's a surprise when it actually gives Ben the alien he wanted.
"LEMME TELL YA SOMETHIN'
, NEW OMNITRIX THAT KEEPS TURNIN' ME INTA THE WRONG THING - YOU KEEP TURNIN' ME INTA THE WRONG THING!
- The Incurseans went from merely looking like anthropomorphic frogs in the Alien Force/Ultimate Alien era to having actual frog-like quirks and tongues in this series.
- The Galvans seem to be getting a similar treatment. Evil's Encore has Blucick displaying a frog-like prehensible tongue and using it to eat a bug, something no Galvan was shown doing before.
- Dr Animo's hammyness and Laughably Evil tendencies are raised to even wackier level than they were in the original show; he invokes classic villain stock phrases, he is Hearing Voices and his monsters tend to look far less grotesque and more cartoonish than they were in the original show.
- Max's Lethal Chef tendencies have taken such an extreme that every time we see him in present day, he is cooking something weird.
- XLR8 was Ben's go-to speedster in the original series, but spoke at a normal pace and only moved quickly when he wanted to. Every time he appears in a young Ben flashback here, he's downright hyperactive.
- Zombozo went from an Axe Crazy Monster Clown to a Denser and Wackier clown-themed villain whose characteristics are more played for laugh.
- The Robots from Dimension 12 only said "Destroy all flesh and the works of flesh" once in their Ultimate Alien introduction episode. In Arrested Development, they constantly repeat it over and over again.
- Gwen and Kevin's character designs in Omniverse take the original concepts of both characters (intelligence and ruffian, respectively) and highlights them even more boldly. Gwen is now freckled and sports glasses to compliment her nerdy girl theme, and Kevin now fashions tattered clothes, with eye liner, and looks like he just got back from a mosh pit show.
- Darkstar's vanity has always been a big part of his character, but "Mystery, Incorporeal" has him screaming out "I'M SO BEAUTIFUL!"
- Flashback with the Other Darrin: In "And Then There Was Ben", the scenes with the original Ben encountering the Omnitrix are almost entirely accurate, but David Kaye voices Heatblast in this particular situation instead of his original actor, Steve Blum.
- Foil: Ben has lots of experience, but little formal training. Rook has had extensive Plumber training, but no firsthand experience fighting villains.
- "It Was Them" mentions as a sidenote of a force field that should have stopped Animo escaping, but isn't paid proper attention to. It then becomes a major point in "Outbreak".
- Billions Tower is seen in "Malefactor." We meet Billy Billions in the very next episode.
- In "Gone Fishin'", the guy listening to the radio hears about Ben sending the Robots from Dimension 12 back where they came from. A few episodes later in "Arrested Development", we find out why they're back in town.
- In "Blukic and Driba go to Mr. Smoothys," Ben says he's been to all 22 Mr. Smoothy's locations... and then sees on his computer that there's a 23rd that wasn't there last he knew, and he'd like to go check it out someday. "Store 23" is about, well, store #23, and there's a good reason why it wasn't there yesterday.
- Most episodes involving a flashback to Malware in the past are in an episode where Khyber the Huntsman appears in the first ten episodes. "Predators And Prey" reveals that they're coworkers. Additionally, Ben is surprised to hear about Malware, indicating that Malware was not just another villain that Ben fought on a daily basis.
- One of the villains at the dwarf star auction in "Special Delivery" is a woman dressed like a cat. This character (Nyancy Chan) would later re-appear as the villain in the Batman Cold Opening of the episode "Tummy Trouble" (though that could be to episodes occasionally airing Out of Order).
- Malware states, in "Malefactor", that he'd "like nothing better than to drain you to an empty shell" to Ben. This is essentially how he destroys Feedback.
- While it is revealed at the end of the episode, the sound effect used when knocking out Ben in "The Ultimate Heist" foreshadows the fact that Albedo's partner is Khyber.
- In "Many Happy Returns", Kevin is gushing about nearly everything in Rook's truck, including a quil-tep nanoshift transformer. We get to see what this actually is in the episode "OTTO Motives".
- Many of the Red Herrings in "Mystery, Incorporeal" seem to be referencing later plot developments, such as Z'skayr's return and Charmcaster's possible involvement in the arc.
- In Ben Again Ben 10,000 notes the problems being caused by the "temporal beasts" of someone named Maltruant, who will later appear in more episodes.
- Fourth Date Marriage: In "The Ballad of Mister Baumann" Baumann and Sheelane can only meet for one day every 5.22 years due to her need to live in high pressure water the rest of the time. Baumann proposes to her the third time.
- Fossil Revival: Psychobos obtains DNA from a skeleton of an extinct Galvan predator in order to add it to the Nemetrix.
- Framing Device: Episodes featuring pre-Time Skip Ben tend to utilize flashbacks to justify why we're seeing an old, albeit never seen, adventure. Curiously, "From Hedotorium to Eternity" lacks one, instead being an entire episode about the 11-Year-Old Ben and a few friends.
- "Freaky Friday" Flip: 16-Year-Old Ben and 11-Year-Old Ben switch in "Ben Again".
- Funny Background Event: One episode has Hokestar's Dumb Muscle attempt to be restrained by the Plumbers while Max talks to Ben and Rook on his badge.
- In "Blukic and Driba Go to Area 51", after Ben transformed into Whampire in the desert sun, we see more of him squirming around on the ground while Blukic and Driba discuss strategies.
- Fusion Dance: In "And Then There Were None", Ben 10,000 shows off the ability to fuse two of his alien forms, such as making a hybrid of Fourarms and Humongosaur. And just to show off how screwed everyone is at the end of the episode, a hybrid of Atomix and Alien X is completely useless against Vilgax's temporal bomb.
- Genre Savvy: In "The Vengers", Ben accurately predicts that Billy Billions, Captain Nemesis, and Commander Kangaroo are too egotistical to work as a superhero team for very long. Once they inevitably succumb to infighting, he tricks them into outing themselves as frauds.
- Godzilla Threshold: When Darkstar is empowered by the energy from Legerdomain and begins a life-draining rampage, Ben decides it's worth the risks involved in turning into Ghostfreak.
- A Good Name for a Rock Band: In "Charm School", Charmcaster summons several rockbats to fight Kevin and Rook. Kevin remarks "Charmcaster and the Rock Bats" sounds like the name of a rock band.
- G-Rated Drug: Feedback was implied to be this to 11-year-old Ben, complete with an "intervention" scene.
- Getting Crap Past the Radar:
- The fact that Pax exists at all is radar worthy. Give up? He's a hippie. And also happens to be a PLANT alien...what is it hippies are known to do in their free time again?
- Kai's constant urge to pet Ben's Benwolf form, as well as his obviously positive reaction to said petting, might raise a question or two with the adult part of the audience.
- When Ben tells Kevin he is being chased by the Rooters, Kevin responds "Who-ters?"
- In "Fight At the Museum", Ester's terror over Ben and Kai being locked in a room... together... at night.
- In part of "It's a Mad, Mad, Mad Ben World, Ben learns that Ben 23's Nanomech is named Teeny-Weeny''.
Ben: Do I even have to tell you that's a bad name?
- Go Mad from the Isolation: Defied when Billy Billion's telling Ben about his time in Dimension 12.
Billy: You know the worst part?
Ben: That five years of isolation drove you crazy?
Billy: That five years of isolation drove me—NO!
- Good Counterpart: Dimmension-23 Seven-Seven, is revealed to be one at the end, working for Azmuth and trying to get the Omnitrix back. The episode ends with him and Dimmension-23 Tetrax drinking Smoothies and waving good-bye to regular Ben.
- The Greatest Story Never Told:
- At the end of "So Long and Thanks for the Smoothies", Ben finally proves to Rook that Alien X is real, takes control of Alien X and rebuilds the whole universe. As it was restored to its state from before the Annihilarrg went off (lest it just be destroyed again), nobody, Rook included, remembers.
- In "Blukic and Driba Go To Mr. Smoothy's," the big battle is the B plot while the subject of the title is the A plot. In the end, Those Two Guys save the day from behind the scenes by reprogramming the robot rats to turn on each other.
- Green-Eyed Monster: Billy Billion, who's entire motivation is jealousy Ben got more attention than him in school (and also, revenge for being trapped in Dimension 12, but that was his own fault). Ben calls him out on it.
- Hand Wave:
- The reason that Animo knew about and resurrected Argost? Before Argost died, he hired Animo just in case.
- "Universe vs. Tennyson" does this with the Retcons and character design changes over the course of the series (with Azmuth as an example) by making them instances of Celestialsapien Reality Warping.
- Happy Fun Ball: The Annihilarg sure doesn't look or sound like a universe destroying doomsday weapon.
- Heel-Face Turn: Slix Vigma, to an extent. Rather than kidnapping people, keeping them prisoners, and forcing them to fight like he did in the orignal series, he hosts (mostly) legitimate fighting tournaments.
- Hex has put his days of evil behind him, and became a teacher at Gwen's college. Charmcaster has gone in the opposite direction thanks to corrupting power and certain evil voices whispering in her ear, though Hex and Gwen both seem confident that she can change too once she's freed from her bad influences.
- Heroic BSOD: 11 year old Ben gets one after Malware destroys Feedback.
- Hijacked by Ganon: In-universe example; in the first episodes, it seems like Khyber the Huntsman is the Big Bad. However, it's eventually revealed he actually is working for Malware, a Predecessor Villain who was introduced in this series, but whose first appearance chronologically happened between the original series and Alien Force, and who had only been seen in flashback at this point.
- Hoist by His Own Petard: Feedback incapacitates Malware by draining him of power in "Showdown Part 2", just like Malware did to many of his fellow Mechamorphs when Ben first met him 5 years ago.
- In "Showdown Part 1", Dr. Psychobos is defeated when Azmuth hijacks the Nemetrix to turn Khyber's pet into the natural predator of Dr. Psychobos's species.
- Hostile Show Takeover: In "Clyde Five", Ben's cousin Clyde tries to sing his own theme song over the opening credits. Ben interrupts him to complain about the takeover and critique his performance.
- How Do I Shot Web?:
- Ben has some difficulties learning how to use the new Omnitrix, resulting in him almost always turning into the wrong alien the same way he did when the Omnitrix was damaged.
- He sometimes has difficulties figuring out how new aliens work. Bloxx, Gravattack, and Ball Weevil are early examples.
- Hunting the Most Dangerous Game: This is a large part of Khyber's motivation to go after Ben.
- Hypocrite: Master Kundo is a traditionalist Revonnahgander, decrying technology and trying to bring Rook Shar back to Revonnah when she tries to join the Plumber Academy. As Rook points out, Revonnah has various kinds of technology, and his hatred of it seems to be arbitrary.
- Hypocritical Humor:
- Ben asks the Rooters why they would want to give humans the powers of aliens... and then realizes in the same sentence that he has described the Omnitrix.
- Ben tries to convince his cousin Clyde to give up an alien weapon. He first attempts to convince him that he can't use it for petty reasons, only for Rook to point out that Ben does this on a regular basis. He then tries to argue that Clyde's inexperience results in random property destruction. The sheer hypocrisy of this statement immediately causes everyone to stare at him, including Mr. Baumann and Pakmar, who could only have materialized from the aether just for that reaction shot. Ben just gives up at this point.
- Idiot Ball:
- Ben, Rook, and Kevin take a long time figuring out how to break down a locked door in "Mystery, Incorporeal" so that Darkstar has time to explain his ritual to one of his minions (and therefore the viewers).
- Gwen fails to understand the fairly obvious code in Kevin's note in "Weapon XI: Part I". She tries running it through numerous code-breaking programs, forgetting she herself has a magic decoding spell. This is so she has to come to Ben and Rook for help, getting them involved in the plot.
- If I Had a Nickel: Ben's response to Khyber saying he was the last person Ben would ever see.
- I Hate Past Me: The future Animo derides his past self for his flaws and mistakes, even blaming him for the accident that put his head in a jar (even though it had yet to happen in the present).
- Imperial Stormtrooper Marksmanship Academy: With the exception of Rook (and only sometimes at that), no one in the setting seems capable of hitting the broad side of a barn.
- Improbable Aiming Skills: While in orbital reentry, an alternate Ben slammed into the Omnitrix's pod with Cannonbolt, pin-balling it right towards 10-year-old Ben with such accuracy that he had to dodge out of the way.
- In-Series Nickname: The Plumbers are often referred to as "red spots."
- Insistent Terminology: As always, Ben dislikes having the Omnitrix referred to as a weapon.
- Instant Expert: Gwen 10, just like in the original series. Using her Omnitrix on the first day she got it, she is still a better fighter than Ben 23, who has spent years fending off alien bounty hunters.
- Insult of Endearment: Before parting ways in the first episode, Ben and Gwen use their old insults for each other (Dweeb and doofus) one last time.
- Intercontinuity Crossover: "T.G.I.S." crossed-over with The Secret Saturdays. See that show's page for more details.
- Interspecies Friendship: Ben with Rook.
- Interspecies Romance: Mr. Baumann and Sheelane.
- I Shall Taunt You: Used by Ben against Khyber in "Of Predators and Prey part 2":
: If you're so great how come it took you five years
to capture me, huh? It took Vilgax
like five minutes
- Blucik and Driba use this against Psychobos in "Frogs of War" part 2.
Driba: The dumbest Galvan is still smarter than any Cerebrocrustacean!
- It's Been Done: In his "Reason You Suck" Speech to Billy Billion, Ben points out how almost all his plans and inventions have already been done by previous villains.
- I Work Alone: Ben has this attitude in the pilot episode, not accepting Rook's partnership (possibly because he feels like he is trying to replace Gwen and Kevin). It comes back in "Of Predators and Prey" with Ben insisting he doesn't need help. He's even worse about it in the present day than he is in the flashback. The infighting and Ben's storming off alone is all a show to lure Khyber.
- Jerkass: Mr. Baumann. Made evident in "Special Delivery" when he can't accept that not every instance of destruction is Ben's fault. He even goes as far as to force Ben to make deliveries without using the Omnitrix.
- Just Eat Him: How NRG disables the Fusion Engine.
- Karma Houdini:
- Aside from being forced to make Ester their leader, the Kraahos don't get punished for trying to kill Ben and Rook in cold blood numerous times and for dumping several tons of molten lava onto Bellwood. The latter action is shown to destroy several buildings and a lot of property in general, as well as probably killing people in the city (and even if it didn't, they sure wouldn't have mind). Meanwhile, characters who commit lesser crimes are arrested and imprisoned by the Plumbers without hesitation.
- Also, Blucik and Driba. While they are not evil, they did cause a large amount of problems with their stupidity and irresponsibility in "Blucik and Driba Go To Mr. Smoothie", by neglecting their duties and leaving with no permission just to find a a Mr. Smoothie. They themselves expect to be fired after this. Not only do they get away with it (they are still in the Plumbers in following episodes), but they actually get rewarded, since Ben gets them a Smoothie.
- Chadzmuth gets no comeuppance for his Amoral Attorney antics. By the end of "Universe Vs. Tennyson", he goes right on with getting criminals released on technicalities, and even gives Ben a bill for his services.
- Karmic Transformation: Master Kundo, the Jerkass Revonnahgander Luddite, ends up being badly wounded and having his arm replaced with a cybernetic prosthetic.
- Knight of Cerebus: Much like Teen Titans, most villains are rather portrayed as comedic or silly, but when it comes to the main villains:
- Khyber the Huntsman basically is an alien Serial Killer, and is portrayed as menacing with little comedy derived from him.
- Malware fairly quickly headed in this direction, starting out in Omniverse with his general flaws (his ego, mostly) as a villain being showcased in each episode he's starred in ("The More Things Change Part 1" in flashback, and "Trouble Helix", his origin story), making him merely appear to be just another monster Ben faced, with a flaw that was easily exploited and humorous. Later appearances show that he learns from any mistakes he previously made, with his depravity and sociopathic tendencies becoming more apparent, his humorous flaws almost completely disappearing, along with being one of the few villains to seriously traumatize Ben.
- Dr. Psychobos, though quirky, is a rare villain to actually win a round. Basically, the main villains of this series are nothing to laugh about.
- Maltruant from "Fight at the Museum" onward.
- Knows A Guy Who Knows A Guy: This is Fistrick's explanation for how he learned of Ravonnah and the Amber Ogia.
- Know When to Fold 'Em:
- Ben and Rook come across a trio of tiny, crab-like aliens making a meal out of a car. Before Ben can even transform, they recognize him and hastily try to reassemble the damaged vehicle.
- Most of the major arc villains share this trait, as Khyber just calls off his pet when he realizes Ben and Rook outnumber him, Malware ran off in the first episode because, as Predators and Prey implied, he already got what he needed, and Psychobos doesn't even bother to stay after he steals a part of the Omnitrix's code.
- Quit Your Whining: A particularly funny example from when Ben is turned 11 again, and goes to Grandpa Max for help.
Max: I know that you're worried, but we're doing everything possible to help. I promise it will be okay.
Ben: ...Come on Grandpa, I just look like I'm eleven. But I'm still sixteen in here. *taps head*
Max: Well then, in that case, stop whining and act your age.
- Race Lift: In the original series episode "Ken 10", Kenny Tennyson had his mother's (Kai) skin tone. In his brief cameo in "And Then There Was Ben", he has his father's skin tone instead.
- This may have just been a coloring error, because when he shows up again in End of an Era he's back to his proper skin tone.
- Reading Your Rights: In "Universe vs Tennyson", we learn that Plumber arrests require that the arrested be read their rights or the arrest is invalid. We don't know how long the rights are, but they must be pretty long if the second clause goes into situations as specific as telepathy.
- "The Reason You Suck" Speech: Ben gives one to Billy Billions, pointing out that all of Billy's 'inventions' are based off someone else's (like ho his pocket watch is an Evil Knockoff of the Omnitrix) and Billy is simply a Spoiled Brat and Green-Eyed Monster who is the cause of all his own suffering.
- Recurring Extra: Many. It's easiest to spot with the aliens in Undertown because of the varied designs. Almost all of the Joke Character Omnitrix aliens Ben turns into in "Outbreak" can be seen (with different colors and no Omnitrix symbol) in Undertown whenever we see it, even before Outbreak (The Worst is one of the first Undertown aliens we ever see.) The XLR8 girl who takes a picture of Ben in "Store 23" is one of the group of members of that race playing on the streets in "Hot Stretch," and she has a name now. (K8E, presumably pronounced Katie.) Of course, it's easier to reuse models for extras, so there are bound to be a few designs seen twice. At the Plumber base, you'll always see one human woman note , and the small Molestache alien note (he lacks the 'stache in original-series-era scenes!).
- Red Herring:
- A partially-meta example. The episode description for "Mystery, Incorporeal" states that "An old enemy emerges while Ben and Rook are visiting Kevin and Gwen at college". One of Charmcaster's rock monsters attacks, suggesting that it's her. However, after the fight, the Omnitrix malfunctions, displaying only Ghostfreak, making him a possibility. Then we're introduced to Xagliv, the Professor of Death, whose name happens to be Vilgax spelled backwards and is voiced by Steve Blum. Turns out that's a red herring too, and the villain is actually Dante, the nerd...who is actually Darkstar in disguise. THEN Darkstar is defeated, and arrested. And then the officer in the car with him is revealed to be Charmcaster, Zs'Skayr is shown emerging from Ledgerdomain, and the very next episode is centered around the return of Vilgax.
- Gwen, of course, references the term when Xagliv turns out to not be the villain.
- "Bengeance Is Mine" introduces us to Bill Gacks, a plumber (not the intergalactic space police kind) who looks a lot like a human Vilgax. Red herring, of course. Him activating Vilgax's contingency plan while snaking pipes happened to be pure coincidence.
- Redemption Rejection: Azmuth attempts to reason Malware briefly in Showdown Part 2, promising to work to heal him. Malware rejects it.
- Remember the New Guy: A lot of characters supposedly from Ben's past are introduced in the flashbacks despite never being mentionned ever. Those include Feedback, Malware and Billy Billion. Most of them are justified, though: Feedback and Malware apparently left Ben traumatized to the point he tried never speaking of them again (this is later revealed to have been Malware destroying Ben's Feedback form in a rather horrific way on top of the other horrific things he did), and he wasn't aware of Billy Billion's existence at the time.
- Reset Button:
- Ben basically remakes the entire universe with Alien X after the Annihilarg is used to destroy it.
- In "And Then There Was Ben", an alternate version of Ben helps Paradox restart all the branching timelines of Ben Tennyson, then uses Clockwork to undo the deaths of all the Bens that were killed in his own timeline.
- Resistance Is Futile:
- Invoked by Emperor Mileous in "The Frogs of War," who adds "...but encouraged, for it amuses me!" Ironically, he then complains about them continuing to resist in spite of his declaration after the battle drags on longer than intended.
- Also used by Proctor Servantis in "The Rooters of All Evil", to which Ben retorts "So's yelling 'resistance is futile'!"
- Retcon: The producers stated that they planned on doing this from the start, and among them:
- Primus, the Omnitrix's planetary database where the Codon Stream carried the DNA codes that allow Ben to transform, no longer existsnote .
- Almost no mention is made of Gwen's Anodite heritage, though they're quiet about calling her powers "magic" or "alien" either way.
- When we first met Mr. Baumann in Ultimate Alien, he was rather friendly and eager to see Ben, saying he had seen him since he was a child. In Omniverse, Baumann has a long history of being "tormented" by Ben, and one of the incidents involving the destruction of his beloved car took place during the previous series... before they could have met again, considering said incident involved DNAliens from Alien Force.
- In Alien Force, Ben functioned as the tie breaker for Alien X. If he could get either Serena or Bellicus to agree to anything then it would be decided. In Omniverse the decision has to be unanimous, with both Serena and Bellicus agreeing.
- In the Original Series, Ditto's duplication power had a very specific way of working; he split himself in half to duplicate, each clone was independent, they all felt each other's pain, and the death of even one of them would cause all the others to die. They wouldn't transform back into Ben until all of them were close enough to fuse back together, and would be attracted to each other when they get close enough. In Omniverse, his duplication power works similarly to that of Echo Echo, with his clones appearing in a flash of green light, being able to vanish and apparently all vanishing automatically when the original turns back to normal. His weakness is now that "if the original dies they all die".
- Zs'kayr ended up banished to Ledgerdomain at some point between the AF and UA eras, even though he got stuck in the watch again in AF.
- In Ultimate Alien, Dr. Viktor was one of Evil!Kevin's victims, and his lifeless body was taken over by King Xarion of Zarcovia. He was defeated by being encased in metal, but Ben and co. were unable to arrest him due Plumbers only being allowed to arrest aliens (despite the fact that Xarion is an alien body). In Omniverse, the Plumbers have Viktor's metal-encased body stored in their basement. This allows the aforementioned Zs'Skayr to enter Viktor's body, where he absorbs Xarion's soul, allowing the original Viktor to regain control and resume being his minion.
- In "Rule of Engagement", it's stated that Julie doesn't like smoothies and was faking it to please Ben, even though the Alien Force episode "Vreedle, Vreedle" had her going to Mr Smoothies with Gwen on her own while Ben was light-years away.
- "Something Zombozo Comes This Way" has Ben suddenly being afraid of clowns again, even though he got over that after Zombozo's first appearance in the original series and demonstrated it after that episode. Zombozo also is retconned into feeding on fear, whereas he fed on joy in the original series.
- Ultimate Alien established that Ascalon, the alien sword built by Azmuth, was the source of legends about mystical swords, Excalibur being mentioned specifically. In "An American Benwolf In London," the sword in the stone is encountered, and it is claimed to be all those mystical swords of legend. (However, many don't know that not every version of the story makes Excalibur and the Sword in the Stone one in the same.)
- In Blucik And Driba go to Area 51, a flashback scene from sixty years ago features Colonel Rozum interacting with Paradox. This despite the fact that when they were first seen interacting in Ultimate Alien, it was made pretty clear this was the first time they had ever met. The flashback also showed Blucik and Driba to be the first aliens Max Tennyson met, and he met them while still in military service. Ultimate Alien showed that his first alien contact was with Verdona, and he became a Plumber immediately afterward. Additionally, the young Max is shown to have black hair, despite the fact that all other flashbacks to his youth showed him with brown hair.
- There was a specific reason that the Omnitrix flew toward Ben in the first series (accidentally tracking Ben's genetic code instead of Max's). "And Then There Was Ben" has No Watch Ben hit the container, causing it to intercept with Ben.
- The Ultimate Alien episode "Basic Training" was about Ben, Gwen, and Kevin attending Plumber training to become fully certified Plumbers. In "The Rooters of All Evil" it becomes a plot point that Ben is not officially a Plumber.
- The Rooters arc does several. Osmosians don't exist; Kevin is just a human with the ability to absorb energy/matter. Devin Levin never existed; Max's partnership with him was a false memory planted in his head by Proctor Servantis. And the Plumber's Helpers weren't born hybrids; they were ordinary human children infused with alien DNA turning them into hybrids (which Helen and Manny originally suspected, in spite of their memory wipes, in the first place).
- At the end of Alien Force's second season, the Highbreed were mixed with DNA from species in the Omnitrix, repairing their DNA and changing their colors. Judge Domstol was later shown to have a red and blue Highbreed as his Bailiff. In this series, Domstol's Bailiff is the same color that all of the Highbreed were before having their DNA repaired. Whether this means the restoration now didn't happen or if it just didn't change the Highbreed's external appearance is unclear.
- In Alien Force, Manny lost a hand while in the Null Void, having it replaced with a metal claw. When he returns in the "Weapon XI" two-parter, he has all four hands.
- That same episode revealed that Gwen liked Kevin back when they were kids, even though he was an Axe Crazy sociopath at that point; No Accounting for Taste?
- In the Ben 10 episode "Ken 10" Ben had a son Ken, but he also had a daughter named Gwen (she's mentioned in the pop-up edition). She appears in the background during Ken's birthday as a silent cameo◊ in◊ the beginning but she doesn't appear, or play a big role in the rest of the episode. However, Derrick J. Wyatt confirmed that she no longer exists◊, and is never seen or mentioned in omniverse, proving that she was permanently written out of the show.
- Reverse Psychology: Ben asks the Omnitrix for Humungousaur when he really wants Wildmutt. Amusingly, it works. It does not, however, in the next episode. Must've been the Unspoken Plan Guarantee of the first one.
- Revision: There are episodes about Ben when he was 11 years old, which are new adventures, despite taking place in the past.
- Revisiting the Roots: According to its creators this is an attempt to return the franchise as a whole back in alignment with the original Ben 10 series. Omniverse tones down the Darker and Edgier aspects and drastically changed the art to a less realistic style as compared to Alien Force and Ultimate Alien. The show frequently has flashbacks to adventures of 10 year-old Ben and reintroduces characters and aliens seen in the original series.
- Rhetorical Question Blunder: Charmcaster rhetorically asks Ben which of them is being unreasonable after he turns down a perfectly good chance to take out Zs'Skayr. Rook, of course, answers as if it were an actual question.
- Ridiculously Cute Critter:
- The Screegit... until it transforms into a hulking monster when exposed to nitrogen.
- Ball Weevil, by Ben's own admission.
- Rubber Man: Ester's species. She's a Half-Human Hybrid but still the same powers.
- Rule of Symbolism: Ben's use of Alien X in Weapon XI is used to get across Servantis's point.
Servantis: A device with as extraordinary a power as the Omnitrix was never meant to be wielded by an unpredictable and immature child!
- Running Gag:
- The Omnitrix hasn't let Ben use Humoungosaur yet, which annoys him greatly. It finally does when he tells it to "surprise him." Go figure. It goes on to do him little good, and he wins the day with Grey Matter.
- Ben has a tendency to get covered in some goo or another.
- Pakmar... has a lot of bad luck with Ben's clumsiness.
- Ditto Mr. Baumann.
- This series continues the tradition of Mount Rushmore getting destroyed in some way.
- "Charmed, I'm Sure" gives us a little girl with a crush on Ben that lasts until Ben's zits (that he got in the same episode) are cured, Hobble's crush on Charmcaster that doesn't even fade when she betrays the group and Charmcaster talking to her purse which is revealed to have a magical miniature that communicate with her. These jokes contained within the episode.
- Kevin's car still gets destroyed every episode it shows up. Kevin's Genre Savvy about it, but not enough to save it. Ever.
- Sci-Fi Writers Have No Sense of Scale:
- The show has Ben constantly boasting that he "saved the Universe a Billion times". While he did accomplished many heroic deeds over the course of the franchise, most of them were a much more limited area, such a town, Earth, the Galaxy or some other planet. The number of occasions where he actually saved the entire Universe onscreen doesn't exceed three times (Secret of the Omnitrix, the Aggregor case and Diagon's return, to be specific), and it seems very unlikely that the universe was so often in danger offscreen for him to save it that many times. Of course, it is Ben talking. This is Lampshaded in "An American Benwolf in London."
Ben: I've saved the universe more times than I can count.
Rook: The official count is three.
Ben: Really? It's gotta be more than that.
- In the same vein, when Psyphon upgrades himself with a Dwarf Star in Special Delivery, he immediatly states his intention to use his newfound power to "conquer the entire Universe". If that thing really had enough power to conquer the Universe, it seems very unlikely that no one thought about using it before.
- When asked to "sign the planet in big enough letters to be seen from the Andromeda galaxy", Ben's actor makes the letters no more than a few feet wide. It turns out that the being intended to see it has a really good zoom feature.
- Sdrawkcab Name: There's a character named Xagliv, which is about as subtle as a Dump Truck. Needless to say, it's a red herring.
- Sequel Hook: "Mystery, Incorporeal" sets up the return of Charmcaster and Ghostfreak.
- Series Continuity Error:
- Gwen states in "Showdown part 1" that Ben's only form to ever defeat Malware was Diamondhead. Flashbacks show Ben defeating Malware with Feedback right in the first episode. Granted, he actually retreated of his own will because he had got what he wanted, but Gwen wasn't supposed to know that.
- In "Predators And Preys", Khyber tries to transform his pet into Grey Matter's predator, but is interrupted by Rook. Come Showdown, we learn the Nemetrix didn't have a Predator for Grey Matter back then: the only Galvan predator, Omnivoracious, is extinct in the present timeline, and is only acquired in the season 1 finale, when Khyber sampled it from a fossilized skeleton.
- Granted, he didn't have Grey Matter's only Successful Predator, but still, all of the other ones were defeated by cunning, inginuity and (if you mind the pun,) a little Grey Matter.
- In "Frogs of War", the population of Undertown evacuates right through the street, exposing themselves and Undertown to the general public. Everyone acts as if both are a big revelation, despite the fact that not only have aliens been routinely invading for years, but by this point in the series live openly among humans and can be seen actually playing in the streets in some episodes. This is a particularly jarring example as it is quite literally part of the basic premise of the show.
- Billy Billions is introduced as being one of Ben's classmates when he was 10 who was jealous of Ben's popularity at school. If you ever watched the original show, you know that Ben actually was incredibly unpopular at school, and only got famous starting with Ultimate Alien. Fans usually try to rationalize it by seeing the flashback as warped by Billy Billions' sociopathic perception of things, but this is at no point stated explicitly in the episode, and if it was true, you gotta wonder why Billy would develop such paranoia toward some unpopular kid nobody cared about instead of a popular classmate, who would have been much more likely to steal him the spotlight.
- Azmuth's attempt to reform Malware by offering to help him find a cure in Showdown Part 2 suddenly makes a lot less sense when you remember Malware technically was cured by Albedo right in his origin episode, and has shown no sign of still needing to feed since then.
- In the first arc, it's specifically stated by all three main villains that Khyber's mission was to get DNA from the Omnitrix so Psychobos could complete the Nemetrix with it. Right in their next appearance, this plotpoint is inexplicably dropped in favour of the Nemetrix suddenly being malfunctionning and requiring a piece of the Omnitrix rather than DNA.
- In his speech to convince Kevin that Ben should be eliminated, Proctor Servantis states that Ben destroyed the universe, most likely referring to the events of "So Long and Thanks for the Smoothies". Not only was this not Ben's fault, Ben actually recreated the universe when it happened, essentially meaning all of existence is owed to his actions. Then again, Servantis might willingly be an Unreliable Narrator for the sake of convincing Kevin.
- The entirety of From Hedorium to Eternity is a flashback to when Ben was 11 years old. Despite this, Zs'Skayr/Ghostfreak has his current design and is referred to by name despite Ben not knowing his name until Rad Monster Party. Kevin also appears in the episode, and meets Cooper, despite being unaware that Ben and Gwen knew Cooper in Alien Force.
- In Ultimate Alien, Albedo used a DNA-altering device to grant him the power to shapeshift into alien forms without an Omnitrix. The Ultimatrix he uses in Omniverse merely acts as a stabiliser and means to access Ultimate forms. In "Malgax Attacks," Azmuth shuts down the new Ultimatrix, leaving Albedo trapped as an eleven-year-old Ben (Even though he should still have had his shapeshifting abilities).
- Set Right What Once Went Wrong: "Let's Do the Time War Again" is a series of these. Ben 10,000 and Professor Paradox keep trying to prevent Eon from unleashing a time beast, but every attempt goes wrong. First time is stopped as a consequence of Feedback's energy blast interacting with the time beast's time blast. Then Bellwood and probably the world is destroyed through Gravattack trying to pin down the time beast with his gravity powers. Finally, with Ben 10,000's help, they manage to de-age the time beast back into an egg, but fail to realize that Eon stole two specimens for Maltruant.
- Shaggy Dog Story: "Rad Monster Party" has Ben and company stranded on a planet and having to obtain a very rare part to get off the planet while Zs'Skayr and his minions try to destroy them. Ben ultimately gets the part, but breaks it while flaunting about it, thus extending their visit to at least two more episodes.
- Shame If Something Happened: The protection racket being used on the alien shopkeepers of Bellwood.
- Shapeshifter Swan Song: In the series finale, Ben rapidly shifts through nearly all his forms while trying to contain the detonation of Maltruant's modified Anihilarg.
- Shock and Awe: All of the forms Ben transforms into in "Max's Monster" (Feedback, Frankenstrike, Shocksquatch, AmpFibian, and Buzzshock) have electrical powers. This was due to Phil interfering with the Omnitrix.
- Shout-Out: Has its own page.
- Shy Finger Twiddling: Attea does this when Ben ( as Bullfrag) flirts with her.
- Special Edition Title: For the fifth Story Arc, "Galactic Monsters". The normal music is replaced with "spookier" music, Ben's movie monster aliens stand-in for the regulars, and has different singers.
- Spock Speak: Rook's entire race speaks in this manner. Lampshaded in "While You Were Gone" when they figure out his father has been brainwashed because he starts to use contractions.
- Spotlight-Stealing Squad: A lot of fans complained that Kevin and Gwen were removed because they supposely were this to Ben, only to replace them with Rook, who is so awesome he ends up stealing Ben's screentime even more. This pic◊ says it all. Later episodes, possibly in response to this trope, either show Ben shining more or keep Rook out of the episode entirely.
- Stable Time Loop:
- Enforced via Easy Amnesia. Present!Animo and Future!Animo are hit with amnesiac gas, forgetting most of the details so that Present!Animo (when he becomes Future!Animo) will make the same attempt, not remembering that he failed, and so that the Future!Animo that has already tried will not come back to try again.
- The final result of "And Then There Was Ben", where No Watch Ben, with the Omnitrix, causes Vilgax's ships shields to fail, the Omnitrix to veer its way to Ben, and then get Ben close to the watch, which causes Ben to go on his path to be a hero, Vilgax's descent into insanity, and the events of "And Then There Was Ben" by default. He also helps recruit the good alternate Bens for the battle that began before the Time Bomb went off.
- The finale reveals that Maltruant is trapped in one: he's defeated by Ben before the start of time, broken into pieces which are scattered by Paradox, reassembles himself, and goes back in time be beaten by Ben once again.
- Stacy's Mom: Ben harbors a not-so-secret crush on Drew Saturday in "T.G.I.S.", who's old enough to be his mother. Her son Zak is disturbed by it.
- The Starscream: After relinquishing leadership of the Kraaho to Esther, Seebik appears in "Special Delivery" vying for Psyphon's dwarf star core. When Ben asks him if Esther knows what he's doing, he replies "I hope not", implying that he is working behind her back.
- Stepford Smiler: Possibly Ben 23; he goes around the whole episode acting immature and joyful, but, at the end of the episode, after a short tantrum when Azmuth removes his Omnitrix, he breaks and admits he misses his grandfather.
- Steven Ulysses Perhero: Bill Gacks. Subverted in that he's not even a Plumber, just a regular, janitorial plumber.
- Story-Breaker Power: Several of Ben's aliens.
- Alien X and Waybig return. Alien X gets even more story-breakery after "Universe vs. Tennyson", when Ben gains complete control over him.
- Gravattack's gravity manipulation. He can prevent any attack from even getting close to him and can slam his enemies into submission with impunity. With two exceptions (one where he timed out, and another where the mass change of Albedo's transformations allowed him to throw off the power) Gravattack has won every single fight he's been in, usually with next to no effort. It was meant to show how utterly badass Eighteight was when she could crawl pathetically toward him for a few seconds.
- Toepick's scary face. Two times he has appeared. Two times it was an accident. Two times the overwhelming threat was immediately terrified into submission without any action on Ben's part. Worse yet, Wordof God is that there is no such thing as a No Sell for this, not even for a robot or Physical God.
- Unless his opponent is a Vulpamancer (Wildmutt)
- Pesky Dust, introduced as a joke character, can put foes to sleep and manipulate their dreams to get them to reveal anything they know.
- Atomix's super strength and nuclear powers. How do you defeat an enemy who has all the same powers as you, but better, and is smarter about using them? You turn into this guy and waste him with sheer power. Just like Toepick, Atomix has only appeared twice at this point, and just like Toepick he was used to effortlessly take down the powerful villains, in his case the arc villains.
- Ghostfreak, now that Ben has a better handle on his powers. Turn invisible, fly close to them, then possess them. Done. Any single powerful threat is down, and can be turned on any other threat. The immunity to Life Drain and the Combat Tentacles are icing on the Took a Level in Badass cake.
- Gutrot's gasses include Instant Sedation and Easy Amnesia.
- Whampire, Up to Eleven. Ghostfreak can only possess one person, but Whampire can possess entire crowds.
- Brainstorm can accurately predict every move his opponents will make and counter them.
- Ben's ability to switch alien forms freely by tapping the Omnitrix symbol should allow him to avoid any unfavorable match-ups, completely removing the common plot point of Ben having to use the alien he's stuck with creatively. In practice he usually forgets about the ability unless his opponent is also a shapeshifter.
- Straw Fan: Collectimus. A big-headed, tantrum-throwing, sedentary, nasally-voice alien with Nerd Glasses, he is presented as a parody of fans of Alien Force and Ultimate Alien. Professing himself to be Ben 10's biggest fan, he is obsessed with Ben 10 trivia and merchandise, specifically "collecting" the latter. However, he disregards the "real" Ben, complaining that the world of Omniverse should be Darker and Edgier and showing interest only in items from when Ben was younger and from a low quality Animesque knock-off.
- Surveillance as the Plot Demands: In "The Vengers", the Vengers recorded the fight between them and Ben without any of them carrying any sort of recording device. The footage shown takes clips from the episode, rather than from an angle a camera would be viewing.
- Synchronous Episodes: "Mud is Thicker Then Water" and "Otto Motives" occur at around the same time. They are linked by phone calls Rook makes to Ben, and "Mud is Thicker Then Water" opens with Rook and Kevin heading off to the auto show featured in "Otto Motives."
- Take That, Audience!: Collectimus. See Straw Fan above.
- Take That, Us: Both "Store 23" and "Collect This" parody the franchise's Merchandise-Driven nature.
- Tailor-Made Prison: In "Vilgax Must Croak", all staff and prisoners are evacuated from Incarcecon to place Vilgax there to leave the rest of his life in solitary confinement, being placed with automated machines to serve him food and leaving him no one to rule over or manipulate. It doesn't quite go this way.
- Talking Is a Free Action: In the first episode, despite there being a bomb crisis with what appears to be little time, Ben and Rook talk without the bomb blowing up, even as they're disabling it.
- Tempting Fate:
- Ben boasts that he doesn't need help. Specifically, while flying as an alien. He promptly times out.
- Lampshaded in "Outbreak", where Rook's tendency towards this irritates Ben, who tells him to stop saying stuff like this. The first two times, when Rook is saying it genuinely, the trope is played straight. When he continues just to tease Ben it is subverted and nothing happens.
- In "Showdown, Part 1", when using Humongosaur to lift Pakmar's truck, Pakmar demands he put it down before he causes any more damage. Ben dismissively states that such a thing is basically impossible... right before Azmuth teleports him to Galvan Prime and takes half the truck with him.
- Ben 23 does this at the end of "Store 23". Everyone from the main dimension immediately braces themselves. The fact that nothing happens is taken as evidence that the laws of physics work differently in dimension 23.
- In "Charm School", Kevin and Rook go to incredible lengths to shield Kevin's car from any potential abuse Ben might accidentally inflict on it. Then a stray magic blast from Gwen zaps it into oblivion.
- Time Travel Tense Trouble: Paradox mentions this when first meeting past Gwen and Max. 11 year old Gwen later finds she also has trouble. Further trouble with tenses came when 11 and 16 year old Gwens cast a spell together.
- Timey-Wimey Ball: The series finale combines events from all over the timeline into Maltruant's endgame.
- Third-Person Person: Pakmar, at least when referring to his shop. Rath also keeps this Verbal Tic.
- Through His Stomach: Rook finally wins Ben's respect by bringing him food he can actually enjoy. In case you don't know, it's chili fries.
- Thrown Out the Airlock: In "The Vampire Strikes Back", Rad Dudesman ejects Ben from his ship through an airlock in the cockpit after Ben insists that he needs to get back to Anur Transyl. He was pretty pissed at Ben for the damage to his ship.
- Throw the Dog a Bone: Baumann has been a miserable Butt Monkey putting up with Ben's destructiveness. "The Ballad of Mister Baumann" introduces his loving girlfriend, who by the end of the episode becomes his wife and he can see everyday.
- Throw the Pin: How the Vreedle Brothers kill themselves early in "O Mother, Where Art Thou?".
- Time Crash: Eon very nearly destroys reality with one in "Ben Again".
- Time Skip: Takes place after some point in Ultimate Alien, as well as showing that aliens now coexist generally peacefully with the human populace.
- Timey-Wimey Ball: Discussed trope. Ben as Gutrot ponders how they could possibly deal with Future!Animo, considering he has access to time travel and all manner of time paradoxes could ensue depending on how they deal with it. He settles on setting up a Stable Time Loop using Easy Amnesia.
- Tiny Guy, Huge Girl: One episode has Fistina winning a date with a Kraaho. I repeat. Fistina is dating.
- Took a Level in Dumbass: Ben. The show took the trope to Flanderization levels on both his teenage self and his 10-year old self, making them both much more bumbling, clumsy and immature while removing a large amount of his badassness from ''Alien Force''. However, sometimes he's Dangerously Genre Savvy.
- Trademark Favorite Food: Smoothies and chili fries. It's rare that Ben is seen eating without one or the other. In fact, he's so famous around the Mr. Smoothies, the clerks will even open after closing just for him. Notably, we see him actually eating chili fries after his love for them was largely an Informed Attribute before (Albedo, stuck in Ben's form, is addicted to chili fries... which at the time we'd never seen Ben eat.)
- Tragic Monster: "Max's Monster" is all about this. Max's former partner Phil (introduced in the classic series episode "The Truth") returns from the Null Void, under the influence of an energy-siphoning monster and begging for help. Max tries to do anything he can to help, and comparisons to Kevin's past are made. Until it's revealed that Phil no longer lives, and the monster is using his body and playing to Max's emotions to obtain more food, at which point his defeat is far less tragic. To heighten the parallel, it's also the official return of Ben's Frankenstrike form from the original series.
- True Companions: Ben's new team: Himself and Rook as time went on.
- Two Lines, No Waiting: "Blukic and Driba Go To Mr. Smoothy" features the titular duo trying to find Mr. Smoothy, while Ben and Rook tackle Trumbipulor. The storylines intersect along the way as Blukic and Driba help them with the mission.
- Underground City: Undertown.
- Unhand Them, Villain!: When webbed to the ceiling by Albedo as Ultimate Spidermonkey, Ben demands Albedo release him. Albedo of course complies.
- The Unmasqued World: Aliens now live openly among humans.
- Ungrateful Bastard: Mr. Baumann towards Ben. He is more concerned about the destruction of his own property rather than the evil that Ben thwarts. In fact, any time his car or his property get destroyed during an alien attack, he is often a jerk about it towards Ben, no matter how little or unintentional Ben contributes to the damage.
- Vagueness Is Coming: The Rooters justify their villainy by claiming to be preparing for a coming threat. Max and Ben believe this to be a lie they cooked up to continue their experiments.
- Vile Villain, Saccharine Show: The show itself is notably Denser and Wackier / Lighter and Softer compared to the previous sequels, but its major villains are an Egomaniac Hunter Serial Killer, a Sociopathic Not-So-Harmless Villain and a Mad Scientist who attempts to commit a genocide of the Galvans.
- Villain Ball: Khyber attempts to make this a Defied Trope, but Ben suckers him into it anyway. He also goes easy on Ben because he wants to personally strike the final blow.
- Villain Decay: Psyphon, Khyber and Albedo all started up as legitimate threats and fairly effective villains in this series. The foremost ended up gradually defeated in more humiliating ways over the course of his reappearances, while the latter two both get very humiliating, undignified defeats by the end of "For A Few Brains More".
- Villainy-Free Villain: Professor Blarney Hokestar has his Skreejit confiscated despite the fact that he was very careful in handling it, never showed any signs of mistreating it, and made every effort to contain it when Ben and Pax caused it to run amok. In the end, all Hokestar had done was the extraterrestrial equivalent of milking a cow. Then again, considering he transported an alien to Earth which could become dangerous when exposed to the atmosphere, its confiscation could be likened to the restriction of ecosystem-damaging animals and plants in the real world.
- Villain with Good Publicity: Kuphulu is referred to as a repeat offender by Scout, yet the citizens of Anur Transyl consider him an innocent during his fight with Ben. This is somewhat justified by the fact that crime is almost non-existent, that it doesn't occur to them that any of their kind could do any wrong.
- Villain World: Anur Transyl.
- Vocal Evolution: A lot of characters get new speech patterns or vocal effects that are quite fitting (if sometimes leaving them sounding little like they did before.)
- In the previous two series, Psyphon and Big Chill (both voiced by Dee Bradley Baker) sounded very calm and stoic. Here, both are more "out there", especially with Psyphon, who has become a full on Large Ham.
- Now Waybig sounds like a stereotypical 1950s Japanese movie character. Considering what he's supposed to be an homage to, it makes sense.
- Emperor Milleous (voiced by Kevin Michael Richardson) has a much deeper voice in this series than he did in Alien Force. It also has a tendency to crack while he's speaking.
- Steve Blum reprises Ghostfreak and Zs'Skayr, but in order to set Ghostfreak (Ben) apart from his evil counterpart, Ghostfreak sounds much less raspy and villainous, and more "heroic".
- Voices Are Mental: When sixteen year old Ben's mind is send back into eleven year old Ben's body (and vice versa) in "Ben Again," their voices travel with them - despite Ben's voicing aging back when he had done so before in "Arrested Development." Notably, this is not just for the viewer's benefit: the other characters notice it as well.
- We Come in Peace — Shoot to Kill: Benevolon in "Blukic and Driba go to Area 51" insists he's on a mission of peace... and to accomplish it he plans to wipe out the entire human species. Hey, he never said it'd be peaceful for them.
- Wham Episode:
- The double episode "Of Predators and Prey"; Khyber finally reveals himself to Ben, but turns out to not be the Big Bad, being instead The Dragon to Malware, a villain introduced in the flashback parts, and Dr Psychobos, a guy we had never seen before. And Khyber's ship is destroyed.
- "Showdown Part 1" reveals that Malware pulled Feedback out of the Omnitrix and destroyed him, showing that Malware can do so much more with the Omnitrix than previously thought (he only used those abilities to switch Ben back to human form and take a sample of its code, giving a somewhat limited look as to what he could do to the watch) and justifying Ben's fear of the character. In addition to that, Galvan B is destroyed, and it turns out Dr Psychobos intends to exterminate the Galvan.
- "And Then There Were None". Vilgax sets off a bomb that destroys all but one universe in the entire multiverse, effectively killing off infinite lives, including the main universe Ben Tennyson.
- Wham Line: In "Max's Monster", Phil is having issues controlling this monstrous creature he mutates into, thanks to Nemetrix experiments being done on him, and parasites in his body leading the idea that the plot will be about trying to cure him... And then Phil says this near the episode's end:
- What Happened to the Mouse?:
- In the first part of "Showdown", Khyber leaves Dr. Psychobos to his own predator, and leaves. In part 2, Khyber completely disappears from the narrative, bearing no mention from anyone nor even being referenced when Kevin adopts his pet.
- In "Collect This", after the organocytes are let loose, they eat through the overpass, and Solid Plugg implies that they would grow to be a large, destructive threat. Then the plot moves on to Ben's actor signing Greenland and the coming of Collectimus, with no mention of how or if the organocytes were dealt with.
- Whole Episode Flashback: Malware's origin story in "Trouble Helix" takes the entire episode to tell. This is framed by Khyber accessing the records in the Plumber database.
- The Worf Effect: In "And Then There Were None", Ben 10,000 turns into Atomic X, a fusion of Atomix and Alien X, Ben's two biggest Story Breakers, and he still is unable to stop Vilgax's time bomb, being erased along with the others.
- Atomix suffers this in "Malgax Attacks"; The Malware-armored Vilgax shrugs off even his best shot, and goes on to hand him his first defeat.
- You and What Army?: In a rare moment of Genre Blindness, Ben says this to Gar. Cue to Gar's personnal fleet showing up.
- You Don't Look Like You: The new character designs. Lampshaded in an episode where Argit asks Ben if he got a haircut, though Argit does that a lot.
- You Have Outlived Your Usefulness: Vilgax says this to Eon, just before the Chronosapien time bomb wipes out every alternate Ben and his timeline, including Eon.
- Eon suffers this again in End Of An Era"; After bringing Maltruant a Time Beast-pulled chariot (having brought Time Beast eggs to him in "Let's Do The Time War Again"), Maltruant pushes him off, and, to add insult to injury, sends him back to his own timeline.
- Your Mom: During Psyphon's auction Zombozo says "Then I told Vilgax 'Know what's really scary? Your mom!'"
