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, they now want to repair the Nemetrix with a piece of Galvan tech from the Omnitrix, and the plot to get DNA from it is completely dropped. Justified, because Malware decided to change his Evil Plan and with a stable Nemetrix, they no longer required having to take the Omnitrix.
Accidental Marriage: Thanks to Kevin's scheming, Ben became the fiance of a Tetramand warrior princess named Looma.
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.
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.
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!
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.
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.
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.
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.
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".
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.
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).
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.
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.
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.
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.
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 TrekMirror 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.
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.
Rath is under Mind Control by Nyancy-Chan for most of "Catfight".
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.
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.
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.
Canada, Eh?: Shocksquatch speaks in a Canadian accent. More precisely, a Newfoundland accent.note Newfoundland is Canada's easternmost province. Sasquatch is a Pacific Northwest legend
The episode "Ben 10,000 Returns" was also confirmed to be ignored in favor of making Ben's future more like the original series Ben 10,000.
Inverted with Ben 10: Destroy All Aliens, which is stated to be classified as canon despite being clearly stated to not be so when it was up.
Canon Immigrant: Gorvan, a character exclusive to the first Alien Force video game, makes a brief cameo in "Special Delivery". He's also The Mole in "Mud Is Thicker Than Water".
Call Back: In "Showdown, Part 1", Gwen tries to get Ben to transform into Diamondhead before he chooses Feedback, though he transforms into Feedback anyway. He uses the term "What goes around, comes around", something he said while using Diamondhead in the first series right before Malware destroys Feedback.
There's also the example where young!Ben quips to Malware that he needs a breath mint since Malware's breath stinks. About 20 episodes later, current!Ben asks for a breath mint since his mouth tastes of Malware.
A minor one, but in one episode the Vreedle brothers help activate a device to blow up the entire universe. Several episodes later, as an idea of what to do that will be the worst act they had ever done, Rhomboid suggests destroying the entire universe.
In 'Max's Monster' early on Max once again hits and stops Phil with a truck with Ben as Feedback draining his energy, with much better results this time around. That an Rook refers to him as "a Phil", in a manner similar to Kyhber in 'Of Predators and Preys 2'.
Cardboard Prison: Despite being imprisoned in a high-security cell at the Plumber Base, not only does Animo escape just by digging his way to the sewers, presumably with the help of his ants, but nobody even notices he's gone until Ben and Rook go to visit the cell, suggesting they never even bother to put security camera to watch him. This was forgivable in the original show, where Animo was kept in a regular-looking prison, but the Plumbers, with all their advanced tech and deal with dangerous aliens, have no excuse.
Averted in "Outbreak." The plumber base has a force field surrounding it that keeps prisoners from escaping. Psyphon and his cronies have to trick Ben and company into completely shutting the energy core down before they can try to escape. How Animo got past this is unexplained.
Played straight in "Special Delivery". Many villains who should be incarcerated, such as Psyphon and his gang, Zombozo, and Fistrick are free in this episode.
Lampshaded in "Something Zombozo Comes This Way". After Rook got turned into a zombie-sadclown in a Circus of Fear, Ben is completely sure it's Zombozo's doing, despite him being held in the prison at the Base. Ben and Grandpa Max takes a visit to his cell, where Ben quickly reveals that the Zombozo in there is a dummy, with a Plumber stuffed inside. Ben immediately tells Max, that the Base really needs to work on it's security.
This seems to have only applied for the Malware story arc however; the two next story arcs, featuring the Inkurseans and Albedo, have been far less dark as a whole, and even episodes from the main plot involve a lot of comedic scenes.
Chekhov's Classroom: Humorous example in "It Was Them". When Ben asks Rook how he knows so much about ants, Rook recites a few facts about their massive population and widespread presence across the Earth. When they catch up with Animo, he lectures them about the power of ants... using the exact same statistics, which Ben proudly proclaims he already knows.
Collector of the Strange: The Space Pirate in "Gone Fishin'?" is collecting ships in bottles to sell at a high price to collectors. That is to say, he collects actual, full-sized ships, bottles them, then sells them. Their crews are of no concern.
Color Failure: In "Special Delivery", Psyphon turns completely white in fear when he sees Toepick's hideous face.
Combining Mecha: Through the combination of an evil A.I., Rook's shapeshifting truck, and four cars, said A.I. is able to make itself a mecha body in "OTTO Motives".
Conservation of Ninjutsu: "Special Delivery" has Ben fighting together an entire army of villains, including several ones (Zombozo, Trumbipulor, Sunder, Fisttrick, the Krahoo...) that could give him a hard time in previous episode of their own and would usually require help to be defeated. When he confront them altogether alone in this episode, however, he takes them down with incredible ease.
Conspicuous CG: A carryover from previous series, where many cars and vehicles are rendered in CG, though this time it's slightly less noticeable.
Ben is seen going near Mr Smoothie, a fast food place he frequently went to in AF/UA, while looking for a place to eat. He decides to not go because he feels it would not be the same without Kevin and Gwen.
In the flashback in "A Jolt From the Past", young Ben gripes about who would be drinking smoothies... while fighting a Megawatt in the Mr. Smoothy, which is just opening.
At the end of the pilot, Rook get Ben's acceptance Through His Stomach by buying chilli fries on Max's advice. This food was mentioned to be part of his favorite in Alien Force, and was frequently used as a Running Gag around his Evil Counterpart Albedo.
Ben and Rook fight Megawhatts, with Ben acknowledging he hasn't fought these things in years (a flashback in the same episode shows that).
Albedo, a villain introduced in Ben 10: Alien Force who is mentioned to have been Azmuth's assistant, is seen before he went rogue in a 11 years old Ben flashback working with Azmuth.
Gwen's Anodite form now wears clothes with some similarities to her Lucky Girl suit from the original series.
In the second episode: all the aliens he transforms into are the Andromeda aliens (barring Shocksquatch, who for some reason replaces AmpFibian).
The same episode has him using the hoverboard he had in his youth (though like everything, it has a completely different design, though he has broken a few of 'em);
In the second part of "Of Predators and Prey", when mentioning people have been trying and failing to get his Omnitrix, Ben mentions a time where someone had "his hand crawl in the Null Void without him", which refers to his first encounter with Sunder.
Phil, one of Max's old partners who betrayed the Tennysons in the first series, is shown to be stranded in the Null Void and is one of the first test subjects for the Nemetrix.
This two parter seems to have a lot of callbacks. At one point, Ben pats Rook, who doesn't get the "there there" gesture and Ben has to explain. Rook later does it back to Ben, who is annoyed by it, which amuses Rook. Now, back in Alien Force, Vilgax had taken the Omnitrix and Ben patted Azmuth, saying this would be all right. Azmuth said "Did you just 'there, there' me?!" (That was from the episode "Primus," which is not considered to have happened by The Powers That Be, interestingly.)
"Gone Fishing" has the villain using a Kraken similar the one in the original series to protect his lair, and bring back Magister Patelliday, a character who had appeared for a few seconds in one Ultimate Alien episode.
"Malefactor" has a lot of them as well, including a reference to Kangaroo Commando, one of Ben's childhood heroes who showed up in one episode of the original show, and a reference to Ben's battle with Forever King Driscoll on Mt Rushmore.
Even the background characters are consistent to ridiculous degrees. The woman seen sunbathing in "Hot Stretch" is the very same woman in "Malefactor" driving the bus that Malware threw a gas tanker at to get away from Ben.
"Arrested Development" has reference to both Captain Nemesis (whose building is shown and mentioned) and his robotic enemies from Dimension 12 (who show up as antagonists in the episode).
The fact that Ben is very bad with blasters. Very bad.
The premise of "Store 23" involves Ben looking for a 23rd Mr. Smoothy, something that he said he was going to do in "Blukic and Driba go to Mr. Smoothy".
In "Store 23," we see a poster of Pax from "Have I Got A Deal For You." Coincidentally or not, Blarney T. Hokestar was in this episode; "Have I Got A Deal For You" was his first (and only previous) appearance.
Also in "Store 23", one can guess the Intellectuary's identity if they've seen Secret of the Omnitrix - his appearance is almost identical to the suit Azmuth wore for his first scene in that movie.
In "Special Delivery," villains (and a couple non-villains) from all across franchise history appear at Psyphon's auction. Some of them are ultra-obscure; you'll find yourself saying "hey, it's that guy from that one episode's cold-open waaay back in the original series." Some people literally have more screentime in this episode's crowd scenes than in their original appearances. A decent number of them even get to take part in the fight for the dwarf star, though most don't speak 'cause all their VAs being there at once would get expensive.
"Return to Forever" features two forever knights based on the original series, the Ninja from the Negative 10 Movie, and Morton and Chadwick from Alien Force. With it they also bring back a device used by the Highbreed, although the Forever Knights have modified it for their own use.
In "Mystery, Incorporeal", Gwen insists on being called "Gwendolyn". In the original series episode "Ben 10,000", her future self mentions that she's been "going by Gwendolyn since college."
Continuity Porn: A lot of the Continuity Nods, cameos and others don't make much sense or don't bring anything to the story, such as Psychobos showing up at Psyphon's audience in "Special Delivery", Exo-Skull (a guy from the Ben 10,000 original future) making an appearance, or the Kraken being used as a watchdog for space pirates (despite not being portrayed as an alien in his original appearance). This as a whole give you the feeling the writers are just giving those cameos to please the fans.
Contrived Coincidence: Gwen and Kevin are in a space ship orbiting Earth for an astronomy assignment when Ben, Rook, and Max call for assistance from Albedo's attack.
When Zs'Skayr alters a shipping manifest to ferry him and the statue of Dr. Viktor to their home planet of Anur Transyl, the ship just so happens to also be carrying Ben. Zs'Skayr claims that this was an unplanned bonus, despite how rare it is for Ben to travel into space.
Ben just happens to get Rath ( a humanoid tiger with anger issues)when he's fighting Nyancy Chan, a villain who can control felines.
Convenient Misfire: In "Mystery, Incorporeal", Juryrig's cannon jams when the owner of the food truck used for parts pops up. This is evidently necessary so that the mana beast can bite the Omnitrix and force Ben to later transform into Ghostfreak.
Cool Car: Double-subverted; when Rook is showing his vehicle to Ben we first see a badass-looking green and black monster truck, only to learn it's a different car and Rook's actual ride actually is the old, silly-looking truck behind it. Then Rook reveals it's only in camouflage mode and can turn into a powerful, heavily armed, spaceship-like vehicle.
Kevin's car has an indestructible Tetramand-made engine block, which is why Kevin has always been able to repair his car despite the constant abuse it suffers.
Creator Cameo: In "Have I Got A Deal For You", Hokestar borrows a scooter from "Y-It's Scooter Rentals". "Y-It" is a variation of the art director's name, Derrick Wyatt.
Wyatt appears as a Galvan in "Trouble Helix."
These are everywhere. Blukic and Driba are named for Butch Lukic and Dan Riba.
When Ben is flashing back to his unintentional break-up with Julie, he can be seen battling against a Sumo Slammers player with the screen-name of "Derrick W."
Crossdressing Voices: Professor Xagliv, who despite looking quite masculine and having a deep voice, is a woman.
Dark Is Not Evil: The inhabitants of Anur Transyl may look like horror movie monsters, but most of them aren't evil. Scout even says that the crime rate there is pretty low. Nonetheless, they are openly hostile towards outsiders.
Dark Reprise: The "Galactic Monsters" arc uses a Halloween-ish remix of the main theme.
Due to the influence of the Incursean DNA, Ben develops an attraction to Attea when he transforms into Bullfrag. The feeling is mutual.
A Day in the Limelight: "Blukic and Driba Go To Mr. Smoothies" revolves around the titular duo, giving Ben and Rook a side plot.
Magister Patelliday appeared very briefly in Ultimate Alien, then made a couple cameos in the Omniverse premiere, and then "Gone Fishin'" came along. We find out he's an old buddy of Grandpa Max and very good at what he does even as his "Barney Fife, but as an alien fish" personality is brought into full focus (the homage was there before, but barely getting a sentence or two meant it was "hey, he sounds kinda like somebody I've heard befo- never mind, he's gone.") It may have to do with the tone shift; in the Darker and EdgierUltimate Alien series he'd not fit in, but Omniverse is—
Denser and Wackier: Even the original show, while light-hearted and often comical, usually kept a more or less realistic setting. This show, on the other hand, isn't afraid to get downright silly on occasions for the sake of Rule of Funny (LEGO-based aliens, the Anihilarg, some of the alien civilians...).
Depopulation Bomb: In "Return to Forever", the Forever Knights construct a generator that will eradicate any form of life which has been programmed into it, in this case most of the species that populate Undertown. Ben, in the form of Jury Rigg, reconfigures it to transform Will Harangue into an alien, instead.
Destructive Savior: Ben, to the point a merchant was willing to endure blackmail from aliens criminals rather than call for his help.
Mr. Bowman reveals that Ben has a long-standing habit of accidentally trashing his car, and had earlier said the same was true of his store. A truck of his is actually in orbit thanks to Ben. Until it came back down thanks to Ben. On Bowman's house.
To be fair he wouldn't have known if he had knocked the car out of orbit back into his house.
Detonation Moon: Malwave blows up Galvan B, Galvan Prime's moon and home of the Mechamorphs. They put it back together once they're restored to normal.
Deus ex Machina: Ben suddenly reacquiring Feedback after making peace with himself and defeating Malware.
Diabolus ex Machina: Khyber's dog has demonstrated predator forms for Heatblast, Stinkfly, Armadrillo, and Crashhopper. Guess which aliens the Omnitrix keeps giving Ben?
Zombozo, to a minor extent; while he always was a minor villain, his appearances in both the original series and UA portrayed him as walking horror and a competent Gang leader with good scheming skills, respectively. Omniverse has him attempting a brain robbery alone, portrays him as much more wacky and merely has him defeated in the first episode's Batman Cold Open, making it the first appearance where he isn't dangerous. Eventually fixed in Something This Way Comes Zombozo, where his powers fading away are finally explained and he gets back to his initial threat level.
"Special Delivery" hits several villains hard with it; a lot of the villains that appear in this episode (Psyphon, Fisttrick, Trumbipulor...) had been previously shown to be big threats that could cause trouble to Ben each of their own. Here, they all team up against Ben, and he basically mops the floor with them.
Psyphon is hit hard with this; after being reintroduced as a Not-So-Harmless Villain in The More Things Change and Outbreak, he gradually gets less impressive, less intelligent and more humiliated over the course of his appearances. By Bengeance is Mine, he Took a Level in Dumbass to the point he can't tell the difference between the real Vilgax (who he has been working for) and a random human plumber who looks only slightly like him.
Zig-zaggued with Darkstar, who is portrayed as still effective and smart in Mystery Incorporated... until he turns back into Micheal Mourningstar. Then his vanity is flanderized to ridiculous levels, and he is easily disposed of by Ben as Ghostfreak in a very humiliating way that makes his defeat from the Ultimate Alien finale look dignified.
Disney Death: Inflicted by Malware to the entire Galvanic Mecamorph species.
Ditto Aliens: Averted. Aliens of the same species are given distinct appearances. This is best shown in Rad Monster Party.
Played straight with the Gourmands; although two subspecies exist, members in each species have the same color pattern (though there is some slight variance).
Also played straight with the Incurseans. Though Bullfrag is a genetically optimal Incursean, average Incurseans look the same. It's no wonder Attea can't find a worthy consort when she becomes High Empress.
Divergent Character Evolution: Perhaps in response to criticisms of the lack of unique traits or qualities of some of the sequel aliens, the sequel aliens have started to be given new traits such as their own sound effects (sometimes when they're moving), a distinct quirk (Spidermonkey makes several monkey-esque chirps), or they're slightly reworked to be less of what appears to be blatantly inspired by previous aliens, whether in appearance or changing their powers a bit. The ones who outright have the same power have been ignored in favor of the originals (Fasttrack is out, XLR8 is back). However, Derrick J. Wyatt has said Fasttrack (and some others) won't appear for the first 40 episodes, which is oddly specific if they're truly intended to be gone for good.
Disproportionate Retribution: Mr. Baumann punishes Ben for just accidentally destroying his car, which was the result of an unprovoked alien attack. (Of course, we find out from flashbacks that Ben's Destructive Savior tendencies have ruined his day a lot.)
Don't Call Me Sir: Ben isn't really confortable with Rook's formality and quickly makes use of this trope:
Ben: "Dude. Call. Me. Ben!"
Downtime Downgrade: Ben accidentally and unknowingly broke up with Julie between Ultimate Alien and this series.
Double Meaning: Collectimus, while shielding his eyes from the sun, wishes the Earth was darker. Of course, any subtlety is lost when he immediately follows up with "and grittier."
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 McDuffie.
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.
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).
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."
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.
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.
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.
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.
Flanderization: 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 even was a 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.
Rath: "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 as well. 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.
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!"
Foil: Ben has lots of experience, but little formal training. Rook has had extensive Plumber training, but no firsthand experience fighting villains.
Foreshadowing: "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.
Fossil Revival: Psychobos obtains DNA from a skeleton of an extinct Galvan predator in order to add it to the Nemetrix.
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.
G-Rated Drug: Feedback was implied to be this to 11-year-old Ben, complete with an "intervention" scene.
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.
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.
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.
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).
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.
If I Had a Nickel: Ben's response to Khyber saying he was the last person Ben would ever see.
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.
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.
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.
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.
Lampshade Hanging: The young Ben uses Feedback in practically all his appearances. When he uses him in "Of Predators and Prey, Part Two", young Gwen asks "Don't you ever get tired of that alien?"
"Showdown", the final episode for the show's second arc before being pushed back, shows Ben's ridiculously frequent use of Feedback and the characters pointing out how, in context, certain times using Feedback make no sense (the first example being a car chase where XLR8 would probably have been the best choice. Feedback is used instead, and running on power lines. The second example has him being used to put out a fire.).
Ben lampshades the Plumber base's status as a Cardboard Prison in "Something Zombozo This Way Comes."
Laser-Guided Amnesia: Gutrot uses a gas that induces short-term memory loss on both the present and future Animo, resulting in the present Animo forgetting how things turned out, and the future version forgetting the whole thing (thereby preventing him from coming back and trying again).
Metaphor Is My Middle Name: Rad Dudesman says this three times throughout Rad. The first time it's "Trouble", the second time "Danger", and the third time "Profit". It's revealed at the end of the episode that those really are his middle names.
Mobile Fishbowl: The pisceans, who travel on land not wearing helmets, but suits that circulate water through them.
Mood Whiplash: "Store 23", so much. The episode starts out like a goofy one, with Ben going to look for a Mr Smoothie with Blucik and Driba. Several goofy characters, such as Professor Hokestar and Liam, shows up, and Ben ends up in an alternate reality where his other self became a reality show star. Then, toward the end of the episode, we learn that in this reality, Max died before Ben got the Omnitrix. As a result, he never had his grandpa to guide him and became an irresponsable, even more narcissic and obnoxious hero who saw all aliens as evil. The one this Ben thought to be the Big Bad actually was his reality's Azmuth, trying to get back the Omnitrix before he ended up killing someone. And to make matters worst, this reality's Ben almost ends up ripping his Azmuth in half.
Morality Chain: Max is the only reason that Ben hasn't become a living advertisement for business. Dimension 23's version of Ben doesn't have Max, making him become what Ben would be without his grandpa. Ben later fixes this by giving Ben 23 a new morality chain in the form of Dimension 23's Azmuth.
Moral Dissonance: Not that he didn't deserve it, but Ben intentionally turning Will Harangue into an alien can rub one the wrong way, as he's supposed to be a hero. Same with Azmuth tampering with Albedo's transformation stabilizer to turn him back into a clone of Ben.
Motive Decay: Albedo had a very specific, sympathetic goal in Alien Force and Ultimate Alien, which consisted in getting his original form back and nothing beyond. In Omniverse, he actually gets what he wanted, and decides to take revenge for all the humiliation he endured, which actually is a logical evolution to his character... and then suddenly goes on a scheme to drain Azmuth's intelligence and become the smartest being in the galaxy. Even though a big aspect of the character was to prove he already is superior to Azmuth. Maybe he wanted to prove he was smartest beyong a shadow of a doubt?
Multicultural Alien Planet: Anur Transyl is inhabited by Transylians (Frankenstrike and Dr. Viktor's species), Loboans (Blitzwolfer's species), Thep Khufans (Snare-oh's species), and Ectonurites (Ghostfreak's species).
Multipurpose Monocultured Crop: Taken to ridiculous extremes with the Amber Ogia fruits cultivated by Revonnahganders on their planet. Seriously, not only are those things used by the population for almost everything, from food to building to drink, but they can also be used to power Death Rays capable of destroying entire planets and develop Mind Control serum.
Mundane Utility: In "For a Few Brains More", Gwen uses a spaceship to do research for an astronomy paper, since getting time on the school's telescope was too difficult.
In "Collect This", Ben uses Kickin' Hawk to play soccer.
Mythology Gag: Flashback episodes about 10 years old Ben have Max using a weapon looking similar to his robotic arm from "Ben 10,000".
Humungousaur doesn't demonstrate his size-changing ability, and is more likely to suffer The Worf Effect in favor of making Ben use more inventive solutions than hitting things. This after Ben spent the whole series to that point trying to re-unlock it. His size-changing ability, however, has not appeared for quite a while in previous sequels anyway, being used less and less as the show went on.
Never My Fault: Billy Billions wants revenge on Ben for upstaging him in school and him being trapped into Dimension 12 (which stopped him from aging)... except Ben had no idea the kid even existed and Billy ended up trapped in Dimension 12 when his own attempt to send Ben there was rebounded off Diamondhead (something Ben didn't even know happened).
In "Special Delivery", Psyphon could have had his dwarf star back without any trouble if he had just returned the fish Ben needed to deliver. Instead, the idea that Ben would trade something so valuable for something so worthless is so confusing to him that he feels the need to voice the thought, thus explaining to Ben why it is valuable and making him refuse to return it. He also at one point had the star while Ben was busy with the other villains. He could have just walked away with it then.
When Ben becomes Gutrot for the first time and has no idea how to use the form, he simply asks the future Dr Animo to enlighten him. Future Animo proceeds to tell him the alien's name and specific powerset, which Ben of course uses to foil his plot.
No Guy Wants to Be Chased: The whole premise of Catfight is this; Ben is creeped out when Princess Looma and Princess Attea both want to marry him, with Nyancy chan wanting to use his Rath form to commit crimes.
Noodle Incident: Ben was trapped as a different alien every week for a month, resulting in Grandpa Max being unable to sleep. Nothing is ever disclosed about this.
Not Growing Up Sucks: Being trapped in Dimension 12 has permanently halted Billy Billions' aging process, trapping him in his 11-year-old body. He tries to exact revenge on Ben by making him suffer the same fate.
The Megawhatts appeared as trickster antagonists as early as the first season of the original series. A flashback in "A Jolt From The Past" reaffirms this. But after a fight and undramatic chase scene in the present day, it's revealed that this time, they're the victims.
After repeated attacks from different forms of Khyber's shapeshifting pet (thus believing it to be many animals), Ben assumes Dr. Animo must be behind all the mutant animals. While Animo has in fact escaped confinement, he's busy with his own plans and hadn't planned on killing Ben until after he finished Phase 1. The pet shows up again to confirm that fact.
Oblivious to Love: It takes all of "Hot Stretch" for Ben to realize that Ester's attraction goes beyond mere fangirlish admiration. Even Rook, of all people can see it.
Official Couple: Still Gwen and Kevin, though Julie and Ben are now broken up, and it seems Ben and Ester are becoming this.
Offscreen Teleportation: Ben as Diamondhead in "Evil's Encore" does this when hanging from a ledge. He somehow made it over to the other ledge.
Only the Chosen May Wield: In "An American Benwolf in London", the Forever Knights try to retrieve Excalibur. Unfortunately for them, it's stuck in the stone and even having super-strength only makes the unworthy strong enough to lift the sword and the stone. Kai Green gets it to budge a bit, though, she doesn't get the chance to finish the job.
Out-of-Character Alert: Ben and Rook realise something is amiss with Rook's family when they start talking about how inferior Galvans are, and when Rook Da desn't show disdain for Ben or for Rook being a Plumber (While using contractions, no less). They don't know for sure until Da uses Dr. Psychobos' Catch Phrase.
Averted when Albedo was impersonating Ben. Rook never caught on because Albedo passed off the changes as self-improvement, much of which aligned with advise Rook had given to Ben.
Out of Order: Several episodes have been aired out of order, such as "Store 23", which is chronologically set after "Showdown" yet aired before it.
Palette Swap: In keeping with the Omnitrix changing Ben's clothes into clothes for the aliens, Ben 23's aliens mostly change the green parts (or, in the case of Shocksquatch, the black fur) on Ben's aliens to a light blue. We also get an arguably more benign alternate Sevenseven in white. (Arguably because who his boss proves to be notwithstanding, he did put a bomb on alternate Ben's arm.)
Albedo's alien forms now follow this more closely. They all have darker color palettes, and Goop is completely red instead of green.
Phlebotinum Bomb: Remnants of the Forever Knight's plan in "Return to Forever", where they build a device that would kill all alien life on Earth while ignoring humans.
Pintsized Powerhouse: Princess Looma, in context anyway. While larger than any human, she's the daintiest Tetramand ever seen, yet also the strongest one ever introduced. She can deliver painful, crushing hugs to her father, Gar, who is the hugest walking tank of a Tetramand we've ever seen, and he considers her his best warrior.
Plot Archaeology: Not only do we have flashbacks to the original series era, elements we haven't seen in ages come back, like the Megawhatts. Also, in the original series' Ben 10,000 future episodes, there was an alien named Articguana that future Ben had. In the present, when lava threatens the whole city, Ben unlocks Articguana for the first time. One of those future episodes introduced Ben's son Ken. Ken was going over the list of aliens in his own Omnitrix, and said "Toepick? That one even grosses me out!" and had it replaced with Grey Matter. Well, the subject of that one offhand line in a 2007 episode is going to show up at some point, and there are even plans for a toy of him. Also, Phil (see episode fourteen of the original series) being one of Malware's test subjects. Anything's fair game!
The appearance of a Krakken in "Gone Fishin'?". It was first (and until now, last) seen in episode three of the original series.
Police Are Useless: The real cops don't really stand a chance against the Aliens or sci-fi-tech-wielding humans that Ben faces. The Plumbers manage to avert this, with Max or Ben leading them, they take down Psychobos's minions, and the escaped prisoners in Outbreak. Patelliday, despite his comical flaws, frees himself from confinement, and helps take down the Villain of the Week.
Portal Cut: As part of the Running Gag involving Ben destroying his property, Pakmar's truck is cut in half when Ben, lifting it as Humongosaur, is teleported to Galvan Prime by Azmuth.
Put on a Bus: Julie meanwhile only makes a single appearance in which she broke up with Ben and got a new boyfriend. Although the two promised to remain friends, Word of God has already made it known that he has no plans for her to come back.
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.
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 pronouced 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, and the small Molestache alien (he lacks the 'stache in original-series-era scenes!).
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. Apparently this is going to be a running gag for the Galactic Monsters arc.
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.
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 The reason given by Word of God is that it makes the Omnitrix needlessly complex, and it's easier to say the device simply changes the wearer into different alien species..
Almost no mention is made of Gwen's Anodite heritage, though they're quiet about calling her powers "magic" or "alien" either way.
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.
Reverse Psychology: Ben asks the Omnitrix for Humungousaur when he really wants Wildmutt. Amusingly, it works.
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.
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
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.
For emphasis regarding the "A Billion Times" thing; Ben's had the Omnitrix, or another shapeshifting gadget, for about six years. That's 2,190 days, or 52,594 hours, or 3,155,692 minutes, or 189,341,556 seconds. This is one of those Badass Boasts that just don't make sense.
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, which makes one wonder why the letters had to be big at all.
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: 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.
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.
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 "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.)
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.
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.
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.
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.
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 is a big one to the Ben 10 fanbase. He even says that he wishes the world was darker and grittier, as a satire of fans of Alien Force and Ultimate Alien.
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. This goes about as well as you'd expect.
Becomes a running gag in "Outbreak", with Rook saying things like "It can't get any worse", to Ben's chagrin.
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". Lampshaded non-verbally by all present.
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.
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 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.
Tiny Guy, Huge Girl: One episode has Fistina winning a date with a Kraaho. I repeat. Fistina is dating.
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.
Also, 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.
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.
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.
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.
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.
Vocal Evolution: 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.
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.)
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.
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.
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.
