These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Some fans assume that Ben's return to immaturity might be caused by him accentuating his Jerkass Fašade as a way to prevent himself from getting too serious and as such prevent him from going Knight Templar like he almost did at the end of Ultimate Alien.
Due to Dimension 23 Tetrax being introduced doing actual rampages in a human city, a lot of fans assume he is still evil, or at least less moral than his mainstream counterpart, and just happened to have been hired by Azmuth at this point. This theory is further supported by the fact mainstream Azmuth has been shown hiring villains before (he did recruit Sunder in Ultimate Alien to get the Unitrix back). Also lending credence to this theory is that Sevenseven is also on 23!Azmuth's payroll, and does similar actions.
Has Phil's mind been completely consumed by his Terroranchula mind, or was he just Evil All Along?
Angst? What Angst?: For someone who just watched the entire universe get destroyed right in front of him, Ben seems unusually cheerful. Granted, he was able to sorta bring everyone back via Alien X, but still he should have SOME KIND OF GRIEVING! Head on over to Fridge Horror to see what the end of the episode might entail and you'll understand what I mean.
Dr Psychobos. The series builds him up as an Evil Counterpart to Azmuth and hinted he was more powerful than he appeared by having him easily subduing both his associates at one point. Moreover, he was one of the few villains to actually escape a confrontation with Ben while getting what he wants. Yet, he is easily outsmarted by Azmuth in "Showdown Part 1". Granted, he is a Non-Action Big Bad, but you'd have expected him to be a bigger challenge for Azmuth as a mastermind.
Sixsix, Sevenseven and Eighteight in "Vilgax Must Croak". For the whole episode, they pursue the Plumbers inside Incarceon and almost eliminate them, with a single one of them sending them running. When the Plumbers come back and confront them again... they immediatly surrender, despite being clearly stronger than them.
Khyber's new pet's Ultimate Form is defeated ridiculously easily by Water Hazard before it could get to do anything impressive.
Zs'Skayr and Lord Transyl. Thanks to Viktor betraying Zs'Skayr, Ben is able to turn into Atomix and create a ball of light that kills Zs'Skayr and weakens Transyl enough for Viktor to capture him, put him in a coffin, and push the coffin towards the sun. The fun thing is how the victory music starts playing as soon as Ben turns into Atomix, before he even does anything. It's like a musical Lampshade Hanging.
While the climax of "Showdown, Part 2" is awesome, no clear explanation is given about how Ben got Feedback back during his fight with Malware; he gets eaten by Malware, has a vision of his past self with which to reconcile his issues about losing Feedback, and then suddenly regains said form even though it was made perfectly clear that the Omnitrix could never get it back. The scene is frankly a huge Deus ex Machina. Amusingly enough, Matt Wayne himself admitted he had no idea what happened during this scene when asked about it.
Earth suddenly being a major strategic point to start an invasion of the Galaxy at the beginning of "Frogs of War", even though all three previous series established it as a backwater planet.
Gwen not liking Lucy to the point of suspecting her of being a traitor in "Mud is Thicker Than Water." In the one Original Series episode where Lucy appeared, there was next to no interaction between the two, but they didn't appear to dislike each other at all, and even in the flashback to their child selves in the very episode Gwen was only mildly irritated with her (far from actual dislike) and got over it quickly since she had Ben to be angry with. Plus, the issue is solved by the end of the episode, most likely to not be mentioned again ever, so what was the point of this sudden?
Blucick and Driba repairing the Annihilarg. They might be Genius Ditz, but it's really hard to swallow that they were smart enough to fix a crushed device from an ancient extinct species (plus, who would have been stupid enough to let them touch the remains to begin with?).
Gorvan being the real spy at the end of Mud Thicker Than Water. There was no foreshadowing, we didn't even knowhe was part of the Plumbers until The Reveal (a fact already hard to explain by itself; see What an Idiot below) and this basically comes out of nowhere just to confirm once and for all that Lucy was a Red Herring.
A question a few fans nagged about was why the Plumbers were working again in the sequels when they were retired in the first series, plus all of the alien members despite being an Earth force. "Malefactor" explained that after the first series, they decided to reinstate the Plumbers.
One was apparently attempted at the end of For a Few Brains More; after many fans complaining that the so-called "perfect" Omnitrix actually worked worse than the original one or the Ultimatrix, Ben actually asks the same question to Azmuth, only for him to answer that Ben is pushing too hard, resulting in the Omnitrix randomizing its time limit. Wether this explanation works or not is, like many other things, subject to debate amongst fans.
The three Aborted Arcs from Ultimate Alien have been salvaged as much as possible:
Zs'Skayr goes into Dr. Viktor's body and consumes King Xarion's soul, freeing Dr. Viktor's mind.
A graphic novel◊ will show what happened to Elena Validus and the Hive nanochips.
Charmcaster's new Omniverse arc still follows up from her aborted Ultimate Alien one rather than it just being ignored entirely.
Alien Force got some flak for allowing Vulkanus to purchase and attempt to terraform the Earth (which would kill everything on it), with the indication that his actions were entirely within galactic law. In "Collect This", when Collectimus buys Earth from Simian, Rook explains that no, this is not legal.
While he has his Let's Get Dangerous moments, Ben is still portrayed as much more bumbling and less competent in this show than he was in the two previous sequels, and has a bad tendency to be turned into a Butt Monkey. Partially justified due to his lack of familiarity with the new Omnitrix, but still extremely irritating.
Bloxx. Some fans think he is an original, delightfully weird alien and raise him to Ensemble Darkhorse level. Other think the idea of a LEGO-based alien life form seems silly and doesn't make any sense, even in the Ben 10 universe.
For similar reason, Liam and his Omnitrix counterpart Kickin Hawks are either considered hilarious or completely stupid.
While Rook has indisputably become an Ensemble Darkhorse, there are some fans who still feel like he is a Canon SueSpotlight-Stealing Squad who make Ben's incompetence painfully obvious. Not helped by the fact the series itself points out how Rook has been saving his butt quite often. He gets gradually better as the story goes on, though.
Khyber is either a Creepy AwesomeEgomaniac Hunter, or a generic villain who relies on his dog to fight his foes. This division of opinion seems to have subsided by "Of Predators and Prey", where it's revealed that he was hired by Malware and he is not the Big Bad as thought.
Blucik and Driba are, depending which part of the fandom you ask, hilarious Plucky Comic Relief or incredibly annoying Creators Pets who cause more problems than they solve.
Esther: a good character and love interest or a complete Relationship Sue.
Ben himself, some frustrated at what they feel is serious character degradation and his lack of maturity, others are either okay or just don't care about it.
Atomix is either loved for his hammyness, badassery and being a Continuity Nod to the Original Series' episode Ken 10, or hated for having a ugly, robotic-like, toyetic design and being a God-Mode Sue.
Albedo manages to be a Base Breaker amongst Alien Force fans: some are happy he is turned into a genuinely effective villain again, others are mad he had to devolve from a sympathetic Anti-Villain to a Card-Carrying Villain for this.
Kai Green; Some fans find her more likable than she was in her first appearance and appreciate that her being Ben's confirmed future wife makes the Ben 10,000 future canon again; other feels her relationship with Ben was forced and she gets too much Character Shilling (she is hinted to be worthy of pulling Excalibur out of its stone, even though none of what she ever did before suggested she was noble enough for this).
Broken Base: At this point the base has been broken down into a coarse powder.
A common division: Original Ben 10 and/or Derrick Wyatt's fans who are glad to see the show going back to its original roots and become "fun" again, and Alien Force/Ultimate Alien fans who are afraid Wyatt might be removing everything brought by the sequels (including the good parts) for the sake of going back to the original show. The fact he confirmed that several sequel episodes would be Canon Discontinuity, that arcs started in the previous series have been aborted, and hinted several times he wasn't really a fan of the sequels doesn't help. And then there are those who still believe in the original series only and see both Alien Force, Ultimate AlienandOmniverse as crappy, in fact resenting Omniverse's attempts at throwbacks to the original.
While many aliens' designs had been criticized in the AF/UA era, especially later ones like Eatle, Jury Rigg, and Fasttrack, many others were already good to begin with, raising some controversy about the point of redesigning them as well (especially the original series aliens, whose designs were critically acclaimed for most anyway). Most notable examples of those unnecessary redesigns include Fourarms now having a mustache and Big Chill being now a bulky bug instead of a skeleton-like skinny creature.
The theme song; some are glad the show gets an actual song with lyrics instead of an instrumental piece again, others feel it's overly childish, even compared to the original show's one;
The Continuity Porn, particularly the flashback around 10 years old Ben; a lot of fans are glad about it, since it brings back an original series feeling; others feel that it's a bit forced and unnecessary (what's the point of trying to make 15 years old characters more like their original selves if their original selves will show up in flashback episodes on regular basis anyway?) and will only end up wasting episode that could have been focusing on the plot.
The fact the show is privileging a Denser and Wackier approach and Rule of Funny over a good plot also is starting to bother a lot of fans, especially the return of Ben's Butt Monkey status and the degradation of many villains, even ones that start off threatening in this series, to jokes.
Then there's the animation style in general, from realistic to "cartoony." Basically, see Transformers Animated. Part of Wyatt's Signature Style is a design scheme that people in the biz call "stylized" and people not in the biz call "Ow, my eyes!" (Or, "Well, it fits this lighter series." That's why it's a base-breaker.)
Vilgax being so far Demoted to Extra; fans who thought he was overused in previous series are glad he finally makes way for other villains, while others complain about him missing despite his importance in Ben's rogues gallery. Similarly, there are quarrels about weither his absence will allow to prepare his return as a proper threat or if it just ends up pushing him further in Villain Decay by making him the butt of jokes whenever he gets a mention.
Zombozo had inexplicably lost his supernatural abilities in Ultimate Alien, and went from a Nightmare Fuel-inspiring Monster Clown to a Denser and WackierHarmless Villain at the beginning of Omniverse. Something Zombozo This Way Comes restores him to his supernatural Humanoid Abomination status from the Original Series, and provides an actual explanation for the loss of his powers in the previous series.
Zigzagged with Ben. His personality owes to the exaggerated moron from Season 3 of Alien Force, much to the irritation of the fans who liked him as a more competent and heroic character, but some episodes like "Malefactor" or "Max's Monster" do showcase him as smarter and more competent. Unfortunately, by the next episode he usually tends to get back to be a moron, and the writers have so far yet to settle on either portrayal.
Eon's design is portrayed as closer to his movie self. Considering many thought the Ultimate Alien version actually was cooler than his movie self, whether it's a good thing or not is up to debate. With that being said, he's much more like a mixture of the various versions, taking the basic backstory of the Ultimate Alien incarnation (he's Ben according to Word of God, as already hinted by him and Ben 10,000 sharing their latest VA) as well as threat level, and the movie incarnation's appearance. Interestingly, there are also aspects of his movie self that were present in UA but left out here, most notably his entire head. It's like UA used half of Movie Eon's design, and Omniverse uses the half that UA didn't.
Albedo seems to be on his way to going back to being a fairly competent Evil Counterpart to Ben as opposed to the Butt Monkey (when this show itself has exaggerated Ben's Butt Monkey traits, ironically) he eventually became in Ultimate Alien. Sadly, the same cannot be said for his motivations. See Motive Decay.
Charmcaster's design, personality, and voice (though it has always been done by Kari Wahlgren) much more closely resembles her original ones than the ones from Alien Force and Ultimate Alien.
Some real effort to undoing villains' Badass Decay seems to be ongoing, with various level of success. Vilgax is given a The Bad Guy Wins moment, but also has much less appearances and is treated more like a joke by the other characters than before. Albedo is promoted to Big Bad rank and made a darker, more threatening villain again after having been downgraded to Butt Monkey after his first couple of appearances in AF/UA (though Azmuth´┐Żs treatment of him at the end nullifies this effort a bit); Darkstar was back to his old badassitude level after having fallen even farther than Albedo had (though he slips once he gets his Mike Morningstar looks back.) It's a shame Psyphon is more of a Butt Monkey every episode when he was so cool that first time he operated solo, but then, I guess someone's got to be the Harmless Villain and it sure ain't Zombozo.
Continuity Lockout: Perhaps inevitable, considering the fact that the show references elements and brings back threats that haven't been seen in a long while (Megawhatts, a one-off threat from the first series), as well as coming right after two of the most arc-oriented entries in the franchise. Taken to ridiculous extremes when they use Gorvan, a character who only appeared in the first Alien Force video game. Anyone who has never played the game can't possibly know who he is, yet he is treated like he has always been a recurring villain.
Also, Blucik and Driba; Derrick Wyatt has mentioned that the team adores them, that their episode "Blucik And Driba Go To Mr. Smoothies" is a favorite amongst them, and that he wouldn't mind them having their own show. However, a lot of fans feel like they are just annoying, and hate their episode for being a big waste of time. Not helped by the fact they are frequently accused of Fantastic Racism toward Cerebrocrustaceans, and are going to get another episode dedicated to them.
Designated Hero: Some actions of the protagonists (often played for laughs) have been perceived by the fans as mean-spirited at best and downright morally questionable at worst. The most prominent examples being Ben turning Harangue into an alien and Azmuth trapping Albedo in the form of an 11-Year-Old Ben. While both victims clearly were meant to deserve that, many felt the acts in themselves were petty, needlessly cruel and un-heroic.
Designated Villain: Phil the former Plumber not the alien monster who took over his body and mind was said by Ben to essentially be less redeemable than Kevin. Sure, Phil was a criminal, but he never did anything as bad as what Kevin had done in the original series. Even without the With Great Power Comes Great Insanity excuse Kevin had, there wasn't anything inherently preventing Phil as he was from turning over a new leaf. To be fair, only Ben was thinking this way, and he may have not been meant to be agreeable.
Azmuth locking Albedo in the form of a 11 years old Ben at the end of For A Few Brains More is played for comedy and clearly despicted as Laser-Guided Karma for Albedo, but many fans felt this was just Azmuth needlessly being a dick to him, especially since it was Azmuth's fault if he turned out that way to begin with. Plus, this was perceived as a unglorified end for a character the story arc had worked so hard to rerail into a credible threat.
Ben and Rook laughing after hearing how Billy Billion ended up trapped for all his childhood in Dimension 12. Granted, the irony is funny from the viewers' point of view, and Billy brought it on himself, but in-universe, that was still a child spending six years in an alternate dimension populated with Killer Robots, so seeing them laught at it kinda makes them appear as assholes.
A lot of fans found the gag of Ben hitting on Drew in T.G.I.S. more disturbing than funny.
Charmcaster's lonely life as The Atoner ruling Ledgerdomain caused her a mental break which she's recovered from but with lingering effects making her more erratic. This is Played for Laughs. Granted, it's not AS bad as it could have been, since her supposed Split Personality is revealed to not be one at all, but the jokes at the expense of her actual personality could still be considered in poor taste by some.
Ear Worm: A first since the original series, Omniverse has a songnote a song is a musical piece that specifically has lyrics, and thus is meant to be sung and not an instrumental piece. And it's extremely catchy.
Rook, big time. Ironically, he was initially seen as a Replacement Scrappy for Kevin and Gwen, but as soon as trailers and later episodes revealed his status as an AdorkableBadass NormalNice Guy, his popularity amongst fans raised considerably. By now, he is the main reason why many skeptic fans gave a chance to Omniverse, and most haters consider him the best thing coming out of the show.
Malware as well, being a major example of Evil Is Cool; many fans feel his potential was underexploited in the show.
Gravattack, for having a power that is one of the most unique in the Omnitrix (one criticism of Ben having so many aliens is the lack of unique traits among them) and having a cool design and actor. It is a little disappointing that he's one of Ben's least-used aliens, though the implications of his powers shows why he isn't used very often.
Princess Looma, the Yandere alien in love with Ben.
Attea has become very popular, especially with the redesign.
While the comic relief characters are hit and miss, Hobble appears to have less haters than the others, particularly since he returned in the Anur Transyl trilogy and proved to be Actually Pretty Funny.
Epileptic Trees: It's popular fan theory that Ben forgot to include Primus from the Universal Rebuild in "So Long And Thanks For All The Smoothies," as Derrick J Wyatt says that, pursuant to the mandate that continuity be "cleaned up," whatever that means, it no longer exists. The universal rebuild has in fact been used to explain everything that is different about this series from the previous one. It helps (or not) that production-wise, it is one of the earliest episodes, rather than Episode 7.
Esoteric Happy Ending: the Inkursian invasion Story Arc is concluded in Frogs of War, where it turns out all that happened was a Batman Gambit by PrincessAttea all along to overthrow her father Emperor Milleus. By the end of the episode, she agrees to leave Earth with the Inkursian Empire in exchange for the Plumbers keeping her daddy in custody, which is presented as an acceptable, if not entirely happy, ending. The thing is, in previous episodes, it had been clearly established that Attea was much worse than her father, being an Axe CrazyPsychotic Manchild motivated by Rape, Pillage, and Burn whereas her father was a more pragmaticGalactic Conqueror. In fact, she almost blew up Earth For the Evulz in her introduction episode (in contrast to her father, who only threatened to do so if she wasn't returned to him). Now, granted, she is sort of in a Dating Catwoman situation with Ben, so she will most likely avoid attacking Earth again, but that's little consolation to the rest of the galaxy.
Attea and Ben; it starts with him asking her (though as a joke) if she will turn into a princess if a guy kisses her; then as the show goes on, she grows more and more obsessed with fighting him personally, to the point she forbids her forces to attack him. And to sell it completely, she actually falls for Bullfrag, his Incursean form, to the point she offers him to come with her at the end. The 'kiss' on the cheek at the end, though, was with Ben as himself.
Ben and Vilgax get a little too cozy with each other in "Vilgax Must Croak". Taken Up to Eleven when Vilgax does a Diving Save and saves Ben's life.
Ben: Did you just do what I think you did?
Vilgax: I uh... I don't know what came over me...
God-Mode Sue: Atomix practically is an instant win button for Ben whenever he is lucky enough to get him.
In 2010, there was a short-lived LEGOBen 10 line based on Alien Force. Now there's Bloxx, an alien who's actually made of LEGO bricks.
Also, when Rook can tell that Ester likes Ben, Ben doesn't believe it and responds by saying "'cuz you know everything about girls!" Turns out he does, especially when Ben realized Rook had a girlfriend.
Eon, introduced just after the original series, was a temporal-based alien with an unexplained Evil Brit shtick, until having him face off with the also temporal-based Professor Paradox, Captain Ersatz of Doctor Who, turned Eon into an Expy of the Master. Even better, the Art Shift applied to the Professor makes him resemble Peter Capaldi!
In Ultimate Alien, 16-year-old Ben countered his 10-year-old self's claim that Swampfire was "just a copy of Wildvine" by throwing seeds to spawn a mass of entangling vines, quipping "can Wildvine so this?" In "Rad Monster Party", Wildvine does exactly that.
In one of the Alien Force video games, John Dimaggio played Vilgax, filling in for James Remar, who himself was filling in for Steve Blum. In this series, Steve Blum returns and functions as The Other Darrin for Adwaita, a role John Dimaggio played before.
With Kevin gone, Rook has become the main character yaoi fangirls can pair up with Ben. Not helped by the fact that 1) he admits himself to be an Ascended Fanboy of Ben, 2) he has been revealed to be of a feline species and 3) he actually seems to dislike Esther when she flirts with Ben...
Certain episodes are absolutely chock full of homoerotic undertones. Special mention goes to "Bros In Space". For a bit of context, the whole episode revolves around Rook's father not approving of Rook's choices—bringing Ben to Revonnah being among said choices—and as a result, it's overflowing with a "why don't you like my boyfriend" sort of vibe. The cherry on top has to be when Rook snubs Rayona, his ex-girlfriend whom he supposedly still has feelings for, because he "does not yet know the plans of [his] houseguest", AKA Ben.
Hypocritical Fandom : Remember all those plotholes and retcons that made fans cry that Alien Force and Ultimate Alien sucked? Yeah? Well don't expect the same fans to complain when Omniverse does its own even more confusing retcons or makes blatant Series Continuity Errors; apparently, it's okay if it's against AF/UA.
I Am Not Shazam: The villain featured in the episode "Trouble Helix" is Malware, not Helix, despite the name of the episode. Helix is the name of the device that was used to create him.
'Food Around the Corner has this big time; as the Plumbers must organise a fragile peace treaty between the Appoplexians and the Ludoans, those only agree to do it if a Galilean (Gravattack's species) presides the conference, as they are known to be wise and patient. Instead of just finding a real Galilean willing to do the deeds, they decide to use Ben (who, remember, retains his usual personnality when transformed) as Gravattack. Instead of just having him use the lock-mode function that was introduced in Frog of War'' four episodes ago (though Word of God says he doesn't have the codes for it), which he was shown to be perfectly capable of disactivating by himself, they have Blucik and Driba implant him a device that prevents him from turning back to human, which he cannot shut down by himself. And on top of that, they leave Ben to preside the conference alone, without any com-link device or other mean to contact him should something go wrong. The whole sabotage of the conference could have been avoided had they just avoided half of those mistakes.
The infamous break-up between Ben and Julie, and by extension half the plot of Rule of Engagement, could have never happened if Ben had just been smart enough to call her back immediatly after the video game incident and explain her what happened.
As stated below the references to the past roles of Yuri Lowenthal, Ben's VA, has caused this to happen. Especially the references the Persona series. Some people think the Persona references are hilarious since they can apply Memes for the Hiimdaisy comics very easily and are now assigning different characters their own Arcana for fun. (With Ben either being The Fool or The Magician.) Other people are very annoyed by this developement, have come to think the writers are incredibly uncreative (which is not helped at all when one acknowledges the writer tendency to reuse plots from the origanl series), and that they should just stop making any reference to Ben's VA other than acknoledging him as the person who, well, plays Ben. This biggest source of argument comes from the writers using a Persona reference during a MAJOR PLOT POINT! Said plot point being Ben regaining Feedback after facing a part of himself he wasn't acknowledging. AKA defeating his shadow. The pro-reference side thought it was a really cool scene why the anti-reference side thought the writers were ripping off a major part of the Persona4 story line. So let's just say the only time it's safe is when people are making Hiimdaisy references and even then you have to tread lightly.
It's the Same, Now It Sucks: There have been criticisms about the show reusing ideas or concepts from the original show, resulting in repetitive parts (such as episode whose scripts seems to be directly based on original show episodes) or Continuity Porn that doesn't make much sense (cameo of the Kraken, a creature that wasn't portrayed as an alien in its first appearance, as used by space pirate for a watchdog, or a cameo in present of Exoskull, a villain from five years in the future at least).
Even though Phil was a bastard in his only original show appearance, Omniverse revealed that, after surviving for a year in the Null Void, he ended up captured by Malware and Psychobos, used as a test subject for the Nemetrix, sent after Ben, apparently gravely injured due to the Nemetrix being unable to function right with him, and then took by his captor again. When he is finally brought back, it turns out he died and his body ended up controlled by parasites.
Ben 23 gets this treatment too. In "Store 23" we first see Ben 23 as more of a narcissist than the original Ben. Then we learn that in this universe, Max died before Ben received the Omnitrix. Without Max, there's no Character Development that helped the original Ben become the hero he is today and no one by Ben's side. All the money and fame he receives in the universe will never replace family, treating 23 Ben more as a Stepford Smiler.
Hell, the original 11-year old Ben may qualify when Feedback's DNA is killed right in front of him by Malware.
Still Charmcaster. She's a Jerkass for doing evil under the advice of the monster who killed her father, who she arrogantly believes is of no threat to her anymore, but a Woobie for still recovering from a mental and emotional breakdown while Desperately Looking for a Purpose in Life.
Love It or Hate It: Fans either love Omniverse for taking the show back to its roots, making many homages to the original show, and giving Rook, or hate it for its overly simplified art style, juvenile tone, and decayed Ben.
Love to Hate: The fans really love Malware (who's easily one of the most vile and despicable villains in the entire franchise) due to him being an terrifyingly awesome and Genre Savvy bad guy with zero moral qualms. This made him really stand out, especially given the new Denser and Wackier approach.
Attea, full stop. The whole Incursean story arc was a plan from her to take over her Father's throne.
As of the Galactic Monsters arc, we can now add Zs'Skayr, as nearly every episode in the arc ended with him pretty much getting what he wanted without much effort.
Mis-blamed: Quite a few fans blame Derrick Wyatt for the Denser and Wackier nature of the show, but this was actually due to Executive Meddling. Since the original series always gets the best ratings while the super-dark Ultimate Alien got the worst, the execs wanted Omniverse to go for a tone closer to the first series, making the writers insert a more comedic tone.
Malware either crossed it either by murdering several Galvanic Mechamorphs in "Trouble Helix" (sure, he needed to feed himself, but he shows no remorse, and is actually mad because Azmuth cures them instead of helping him) or by using Phil as an unwilling test subject.
Ben 23, of all people, almost crosses it by attempting to rip his dimension's Azmuth in half. He is fortunately stopped before this happens.
Dr. Psychobos crossed it when he came up with a plan to assassinate Azmuth and commit genocide on the entire Galvan species.
If the above didn't count for Malware, helping Psychobos do thatto his own species certainly does for him as well.
Rad Dudesman crossed it in The Vampire Strikes Back by throwing Ben out of his ship just because Ben stated that he would be locked out of Omnitrix functions for a long time if he didn't get within range of a new DNA sample to be acquired. Either Ben would be killed if he didn't transform into a flying alien, or if Ben survived, he would suffer more abuse from the inhabitants who hate him.
While the concept of a Doomsday Device able to destroy the whole universe is quite scary, it's a bit hard to take it seriously when it's called "Anihilarg."
Trumbipulor tries to invoke Nightmare Fuel with his robot minions by designing them on the scariest, most threatening-looking creatures he could think of in the galaxy. The problem is, he is afraid of mice, which aren't exactly considered scary by human standards.
Padding: In "Frogs of War Part 1", the Randomizer function seems to have been added to the episode just to give a problem to Ben, as it doesn't really add a whole lot to the episode considering Ben's problems and frustrations with the Omnitrix already (common problems include the time limit's varying length and changing into the wrong alien a lot), and takes up a few minutes in the least. The Omnitrix could have glitched out and there really wouldn't have been much of a difference.
No Yay: Attea and Ben/Bullfrag. Even excluding the Squick involved by the fact Attea is an Anthropomorphic frog while Ben is human, there is the fact that Inkurseans grow faster than humans... meaning Attea is technically a lot younger than Ben, which can be seen by Bullfrag looking like an adult rather than a teen.
Pandering to the Base: The show as a whole is obviously intended to satisfy all the original series Ben 10 fans that complained about Alien Force and Ultimate Alien being too different; as a result, we get characters being redesigned to look closer to their original series selves, several characters and elements from the original series coming back (including one-off characters such as the Megawatts), and flashbacks parts and episodes taking place in the original series era. Oh, and Kevin and Gwen are Put on a Bus, possibly to satisfy those who complained about Romantic Plot Tumor. Well, at least they didn't try to satisfy the Bwen fans...
Pesky Dust was, with the other Joke Aliens listed in the scrappy entry below, disliked due to poor design and not having his power revealed. When said power actually was revealed, it turned out to be original and creative enough to at least make him slightly more likable to the fanbase.
Many who didn't care for Kai in her Original Series appearance came to love her when she appeared in Omniverse and now much more people accept her as Ben's future wife. Of course, given all the other Shipping alternatives Ben has in this series, Kai still has her fair share of detractors.
Many of the comedic new characters such as Hokestar, Blukich, and Driba are usually considered fairly annoying or pointless to the narrative. Doesn't help that, in Blukic and Driba's case, they also are Creator's Pets and show signs of Fantastic Racism.
Pax deserves a special mention, being a walking hippie stereotype with Animal Wrongs Group tendencies whose very existence contradicts the Original Show (where Florauna were portrayed as a feral and carnivorous in Secret of the Omnitrix).
Harrangue managed to get even more hatred than he already had in Ultimate Alien when he praised the Incurseans for invading Earth and getting rid of Ben.
The aliens introduced in Outbreak (namely Walkatrout, Pesky Dust, Molestache and the Worst), due to all four of them having poor designs (the design process was literally just picking some of the preexisting "civilian" background aliens) and being introduced as nothing else than Joke Characters. Pesky Dust had its powers revealed 28 episodes later, and the others, if they even have powers, haven't had them revealed.
While Rad Dudesman wasn't particularly disliked when first introduced, he has started becoming this trope after his portrayal in Galactic Monsters, where he Took a Level in Jerkass.
Collectimus, due to being a very obnoxious character and a blatant Take That, Audience!. Fans, especially those who liked the Alien Force/Ultimate Alien era, were not amused.
While the fourth arc started out promising, it included slightly more fillers than previous arcs (its storyline was only three episodes long and took some time to actually start), and its finale was generally considered very disappointing due to undoing the Character Rerailment that had been done with Albedo, an Ass Pull used to bring back Kevin and Gwen (whereas they had actually credible reasons to be there in the previous finales) and featuring some rather anticlimatic fights. The arc also included episodes where protagonists did rather morally ambiguous actions that placed them in Designated Hero territory in the eyes of some fans.
Zs'kayr's cloak becomes this when you realize that it's not a cloak at all. It's the "skin" that he had when he revealed what he really looked like, meaning that Zs'kayr is wearing his own skin as a hood.
Albedo has been established to not give a damn about what others think, and will bend the truth to himself to make sure nothing is his fault. However, it's implied that, at the end of "For A Few Brains More", that Azmuth messed with Albedo's Omnitrix, forcing him back to a Ben form, and a younger Ben form at that, meaning that Albedo just might have some legitimate problems with Azmuth.
Dr Psychobos indisputably is racist toward Galvans, and his accusations toward them of arrogance is clearly meant to have him appear as a Hypocrite. However, some comments made by Blukich and Driba about Cerebrocrustaceans suggest that his arguments of Galvan arrogance might have some credence.
Ben finally gets called out for his arrogance in "Predators and Prey Part 1" by Rook, who can't stand it at this point, a sentiment that many fans have felt since Omniverse began. While part 2 revealed that it was a charade, he seriously meant what he said to Ben about his arrogance.
Comments from Blucik and Driba indicating that Galvans are smarter than Cerebrocrustaceans might have been an attempt of this trope to those who considered Brainstorm a Replacement Scrappy to Grey Matter, but it didn't exactly worked as intended; if anything, it made Blucik and Driba look like racists.
Probably unintentional, but those amongst the fans who dislike Blucik and Driba might enjoy this part of dialogue from "Store 23":
Azmuth: "You two are brilliant scientists."
Blucik and Driba: "Oooooooooh!"
Azmuth: "By Earth's standards; for a pair of Galvan, you are remarkably unintelligent."
Blucik and Driba (disappointed): "Oooooooh...."
The Ship Sinking of Ben/Julie came with Ben unintentionally hurling insults at Julie while playing a video game. The fact that Julie was so unpopular with many of the fandom due to derailment in Ultimate Alien couldn't be a coincidence.
Possibly as an answer to fans complaining about him being a Karma Houdini in Ultimate Alien, Will Harrangue essentially gets everything in the face: Ben "accidentally" sprays him as Water Hazard in Frogs of War, he starts losing viewers after siding with the Inkurseans during their invasion, and a vengeful Jury Rigg mutates him into a tentacled alien.
Oh so much, for any given subject. The artstyle is the most frequently listed exemple, but there are many, many more.
A special mention has to go for T.G.I.S., the crossover episode with The Secret Saturdays; the Saturdays were completely redesigned to fit the Time Skip and Omniverse artstyle, leading to some changes that weren't necessarly well-received by the series' fans.
In-Universe, Collectimus says he prefers the old version of Mr. Smoothy to the new one.
Another special case worth mentionning with Zs'Skayr; even those who found his portrayal in this series satisfying generally agree turning right-side up his iconic upside-down skull was a stupid move.
The Vreedle Brothers; after the Character Development they got in Ultimate Alien and their Heel-Face Turn, the writers decided that they were better as villains and just had them blow up the Plumber Academy before being back to being Con Men. Especially annoying in that this was totally unnecessary: if they wanted villainous Vreedle Brothers, they could have just used a separate pair of clones that were still criminals, seeing how Con of Rath etablished there were an army of them.
A possible subversion, as it seems that what Derrick Wyatt had in mind for her was overruled by other writers on the staff, as Charmcaster is going to remain in the neutral zone in Omniverse as Physical GodDimension Lord of Ledgerdomain. It may still count as a waste since the redemption arc remains canned (it's been confirmed that her true Meaningful Name has been written out, after all) and she'll likely make no progress past where she's at, but it's better than a full regression into evil in any case.
Also, when Albedo absorbs Azmuth's intelligence in For A Few Brains More, he has a Heel Realization about the Universe and seems about to redeem himself. Instead of using this to make his character evolve and have him do the right thing, they had Ben seize the opportunity to trick him and ended the conflict with a fight so Ben could show off his new alien Atomix.
Did you think the prospect of Phil redeeming himself sounded interesting? Too bad, it turns out that Phil was actually killed from the inside out long ago and a parasite has taken his body and had only been pretending to be The Atoner. Combined with the Vreedles, Charmcaster, and Albedo examples above, many fans at this point are getting sick of Kevin being the only villain to be allowed a Heel-Face Turn.
Also, Elena Validus has been confirmed to have a non-speaking cameo coming up and that's it. And it will be as Elena, not as the Hive Queen, meaning she was cured of her condition and her problems from the previous series were resolved completely off-screen: another case of Aborted Arc due to Dwayne McDuffie's Author Existence Failure.
"So Long and Thanks for the Smoothies" involves Ben and Rook trying to prevent a Doomsday Device from falling into the wrong hands, and ends with Ben using Alien X to rebuild the universe. A lot of fans feel the whole thing would have been much better as a serious series finale, or if at least the characters had to deal with the changes caused by such a major event (Ó laInfinite Crisis). Instead, we get a random comical episode that has seemingly few to no impact on the story. The only change made was a new design for the Mr. Smoothy store that Ben loves to visit and that it "doesn't taste the same." However, many have assumed that the changes to characters and the changes to canon thus far only discussed in interviews are because of it. That would make much sense but so far it's been... well, a perfectly good idea that's been wasted.
As of "Showdown, Part 1," Psychobos and Malware's plans for the Nemetrix amounted to using it as a glorified distraction. Khyber alone has it now, but as far as the other two's purpose for it, it's largely disappointing. As a matter of fact, Malware is able to pull out his plan of his own without using the Nemetrix a single time, making you wonder why they worked so hard during five years to complete it when just recruiting bounty hunters or killers to distract Azmuth would have worked just as fine.
In "Showdown Part 1", they introduce the natural predator of the Galvans. Due to its avian nature, some fans believe that it should have been a peacock, using Ben's fear of them to it's advantage. It wasn't.
Khyber hacking the Plumbers' database for information about Malware in "Trouble Helix", as well as the fact he helps Ben and Rook in "Malefactor" suggested he was a Dragon with an Agenda who intended to conspire against Malware at some point. This is never brought up in later episodes, or at least not farther than him being obsessed with getting Ben as a trophy.
Talking about Khyber, it had been suggested in previous episode that he actually cared for his pet, a theory fans liked to support. The writers apparently feared this would lead to Draco in Leather Pants, so they had Khyber leavingsaid pet behind in the finale, despite the fact it was entirely against his advantage (see What an Idiot below), completely dropping the idea.
"Showdown Part 2" has the protagonists of all four series (Ben, Max, Gwen, Kevin, and Rook) coming back and teaming up altogether to stop Malware. How do they do so? By splitting up immediately for various tasks, with Ben fighting Malware alone, Rook and Gwen merely acting as pilots and assistant to Azmuth, Max helping Blucik and Driba to repair a station (by giving up his beltbuckle, no less), and Kevin doing absolutely nothing, instead just having a short subplot where he befriends Khyber's pet. In the end, we don't get any stand of all of them against Malware, who Ben defeats on his own, with the sole help of the Galvanic Mechamorphs and Azmuth. Talk about making Ben's friends even more useless in a fight than they were in Alien Force...
The show establishes that aliens are a well-known fact among the public, and that they can walk among the populace peacefully. This could have been potentially used to develop issue about Fantastic Racism and how the population is adapting to this. However, the story usually doesn't do anything with the idea, usually just showcasing Ben's interactions and treating everything as if nothing's changed. The lack of use of this idea may have even resulted in a particularly bad, somewhat grating continuity error, where "The Frogs of War" reveals them to the human race for the first time, despite previous episodes, seasons, and series contradicting this as Earth has been attacked by aliens several times now.
The flashback in "Showdown Part 1" implies that Ben's love of Feedback might be caused by some sort of addiction to the form, to the point Azmuth actually moves to Earth to warn him about it. This idea is used only as an excuse to get Ben angry so he will lose Feedback to Malware a few seconds later, and is never brought back again, even after Ben got Feedback back.
The very premise of the show: having Ben playing a Big Brother Mentor role toward Rook could have been a genuinely interesting development for the character, not to mention a logical follow up to his evolution over the course of the previous shows. The problem is, he Took a Level in Dumbass and acts more immature than ever, making Rook appears as a Hypercompetent Sidekick who actually is much more mature than him, so the whole point is lost.
Malefactor had Malware absorbing a weapon known as the Tachyon cannon, stated to be able to "rip life forms apart on a molecular level". Such a thing would have been perfect to justify him later being able to destroy Feedback. However, the Tachyon cannon is never mentionned again after this episode, and Malware instead destroy Feedback with a new abilityhe pretty much pulls out of his ass.
When it was revealed the Galactic Monsters story arc would have Ben travel to the Anur system, many fans were enthusiastic about seeing the various planets and their inhabitants. In the end, the arc chosed to focus on only one planet (Anut Transyl), ignoring all the other planets in the system and treating Transyl like if it was the home planet for all the Anur aliens. Their culture was also barely explored in favor of portraying Anur Transyl as a stereotypical Halloweentown.
Tough Act to Follow: One major downside about Malware being an Ensemble Darkhorse is that he was such a great villain he made every single Big Bad following him look pale by comparison. His two immediate successors (Attea and Albedo) were former minor villains promoted to Big Bads with comical quirks (in contrast with him being a Knight of Cerebus with a major case of Vile Villain, Saccharine Show), and even a more iconic villain such as Sz'Skayr couldn't compare thanks to his arc being ridiculously short and wrapped up very anti-climatically.
Fistina's face in "Special Delivery" when she gets a date. Seriously.
Played with in regards to V.V. Argost. He's, like everyone else in the show, stylized and exaggerated, but his mask has a surprisingly distinct, "fake" look to it.
The Untwist: Wait, so Lucy wasn't the spy? What a surprise! After all, it's not like if any Genre Savvy viewer would have easily identified her as an obvious Red Herring, especially since Gwen had next to no reason to suspect her beside her petty dislike of her...
If you think about it, Khyber really didn't need to leave his pet behind when he escaped in "Showdown Part 1"; since the Nemetrix works only on non-intelligent beings, that means he will have to find a new pet to replace it and train it to obey him. Moreover, Azmuth would have used the pet to track him had Malware not distracted them.
Yeah, Dr. Psychobos, we know you are a genius, but do you seriously believe the shapeshifting kid who saved the universe a billion times isn't a threat to your plans?
Almost everythingBlucik and Driba do enters in that territory, the cake probably being when they leave their duties to go look for a Mr Smoothie while the Plumbers are in the middle of a crisis.
Ben treats putting Vilgax in Incarcecon rather casually. He's survived several incidents where he was supposed to be dead and has come closest to getting the Omnitrix. As pointed out by Max, Ben should be the first to know Vilgax is not to be underestimated. Ben ultimately pays for this at the end of the episode, where Vilgax gets away.
The very reason Ben broke up with Julie is because of Ben's sheer stupidity. Seriously, what kind of complete moron would keep playing video game while his girlfriend is talking to him at the phone?
If that wasn't bad enough, Ben never once considers to call her when she stops contacting him after the event, yet still considers Julie to be his girlfriend as of "Rules of Engagement." That's... illogical, to put it lightly.
In Frogs of War, Kevin, Gwen, Rook and Blucick trusted Argit in their rebellion. This goes as well as you'd expect.
In Return to Forever, Ben tries to chase Sir Morton, who kidnapped Jimmy Jones. You'd expect him to just transform in XLR8, Fasttrack or Jetray and easily catch up. But of course, we need Rook to be of some use, so he just runs in human form and eventually gives up to jump in Rook's vehicule.
Also in Return to Forever, Ben as Lodestar is fighting the Forever Ninja, which is a robot. Rather than using his magnetic powers directly on his metal opponent or even the metal vehicles they're both standing next to, he only tries to use them on the shurikens that are being thrown at him. When the shurikens turn out to be wood and he can't control them, the Forever Ninja is able to completely hold Ben at bay.
The Plumbers in Mud Thicker Than Water for allowing Gorvan, a renegade Plumber (it's hinted he already fought with Ben and Gwen before in this continuity, so his backstory from the Alien Force game is still most likely canon) to still be part of them. Even assuming they didn't know who he was, you got to wonder why they never questionned the fact one of their member never removed his suit.
Azmuth isn't an idiot, but you still have to wonder what he was thinking when he came up with the "randomizer", a function that causes the Omnitrix to uncontrollably turn its owner into random aliens and basically serves no purpose other than make it even more difficult to use.
In A Fistful of Brain, Ben is trapped in Albedo's and Khyber's hideout, in a death game with Khyber chasing him. To run away from him, Ben turns into Ditto, reasonning Khyber won't be able to chase them all at once... Except the Original show made it very clear that if one of Ditto's clone is killed, all the others will die as well. Meaning this choice of transformation is a perfect way of making things easier for Khyber.
This weakness was retconned, as detailed on the Ben 10 Omnitrix Aliens character page.
Ben is told at the end of A For a Few Brains More by Azmuth that the reason the Omnitrix keeps giving him the wrong alien is because he is pushing too hard. In the next story arc, he is supposed to know that, yet keeps pushing just as hard, despite supposely knowing it will get him the wrong aliens.
When Ben asks Future!Animo to explain what his new alien Gutrot does, Future!Animo goes ahead an explains it to him, in spite of the objections of his present day self, allowing Ben to near-effortlessly beat them. What's odd about this is that it reverses the characterization the two Animos had had throughout the episode; present day Animo had been the bumbling insane one, while Future!Animo had been competent and intelligent.
Ben, transformed into Swampfire, an alien that can control plants, being attacked by a horde of plants, does not attempt to control the plants. Only when his Puberty Superpower gives him the new ability to control them without trying is this obvious solution reached.
According to Wordof God, every time Ben gets the wrong alien it's simply because he selected the wrong one or is being so rough with the device that it is malfunctioning. This is understandable when he's cycling through 50+ aliens under time pressure, but in situations where time is not a factor or when alien selection is particularly important, Ben's repeated failure to turn into what he wants veers into severe Idiot Hero territory. The most egregious example so far is in Catfight, where Harmless Villain Nyancy-Chan was neither running away nor attacking, but Ben still couldn't be bothered to be careful enough to avoid selecting the one alien he had that was vulnerable to her Mind Control.
In a nutshell, any time they bring back an old alien but find a new voice actor to play him. We got this to some degree with AF and UA, with Dee Bradley Baker voicing all of Ben's aliens old and new save Rath, but he is a Man of a Thousand Voices whose portrayal is such that you'll hardly notice. The new ones will make you say "What do you mean that's supposed to be Cannonbolt?!" However, a lot of the new voices are quite appropriate, such as XLR8's accelerated speech.
This is definitely in effect for fans of The Secret Saturdays as many people reacted negatively to the fact that the titular family were voiced by different voice actors in "T.G.I.S." than in the series proper.
However, this is somewhat justified in Zak's case. T.G.I.S. takes place three years after The Secret Saturdays ended. Zak was thirteen at the end of his series but he's sixteen here. (The Saturdays went through a three year time skip, according to Animo and Argost anyway.)
