YMMV / Ben 10: Ultimate Alien

  • Anvilicious: "The Widening Gyre"
  • Anti-Climax Boss:
    • Aggregor; after half a season building him into a nearly unstoppable Magnificent Bastard, he is defeated quickly by a psychotic Kevin.
    • Darkstar became this in the first season finale, having been defeated with a push of a button.
  • Author's Saving Throw: Alot of them are made here.
  • Broken Base: On many, many subjects. The Ultimate Aliens especially. Others include whether this series is good as the two before it, whether it's successor will be better or worse, and so on and so forth.
  • Character Rerailment:
    • Ben's immaturity in Alien Force is heavily downplayed, making him a bit smarter and more responsible as he was in the first two seasons of that series. The result is more of a comfortable mixture of the traits that people liked in Alien Force, but still kind of prone to poorly thought out and emotional responses the first series had.
    • Vilgax, while not as monstrous as he was in the initial series, is made into a Magnificent Bastard. He successfully tricks Diagon!
  • Complete Monster: Aggregor is an Osmonian warlord who was wantonly murderous in his quest to achieve omnipotence. Aggregor killed aliens by absorbing their energy and matter to gain their powers. Generally this caused his victims to turn into desiccated husks, but for his plans to become powerful enough to reassemble the Map of Infinity, he turned five aliens into energy and absorbed them into himself. Aggregor killed Magister Prior Gilhil by stabbing him in the back, killed two other Plumbers by sucking them into space, and absorbed the life and powers of a pacifistic alien just because he could. His two most vile crimes, however, were when he nearly destroyed an entire inhabited world by stealing a component from the device that kept the planet from breaking apart, and when he tried to kill and absorb a baby alien capable of Reality Warping to complete his ascension into godhood.
  • Continuity Lockout: If you haven't seen either Alien Swarm or Race Against Time, you won't really understand the context regarding the Swarm, Eon, or the Hands of Armageddon.
  • Conflict Ball: Ben suddenly deciding that it's absolutely necessary to kill Kevin in the first season finale, even though he never focused on killing any previous enemies (including ones which were much more of a threat than Kevin), and Grandpa Max points out that he's acting out-of-character in the show itself.
  • Creator's Pet: Inverted with Aggregor; he is fairly popular amongst the fans for being an extremely competent villain, but the writing staff apparently dislikes him, and the one who came up with his design even admitted being embarrassed with it. He apparently was going to have a minor role for the Rooter story arc in Ben 10: Omniverse (where he was going to be killed off, with that), but the idea was dropped because the writers were in no hurry to bring him back.
  • Darkness-Induced Audience Apathy: In the first arc, Ben, Gwen, and Kevin are largely incapable of defeating Aggregor, who manages to get away at every turn until Kevin absorbs energy from the Omnitrix to defeat him, but goes insane in the process, and Ben decides to put Kevin down, completely deciding this on a whim, making Ben largely unsympathetic, and the heroes almost useless due to running into the same problems they did with Aggregor. The second arc isn't as bad in this respect, but has other problems, and the darkness is still piled on thick with episodes like "The Purge", "The Enemy of My Frenemy", "To Catch a Falling Star", "Night of the Living Nightmare", and anything involving Diagon. This was apparently a contributor in why Omniverse is the way it is, as Ultimate Alien got the lowest ratings of any Ben 10 series.
  • Ensemble Darkhorse:
    • Jury Rigg may be a more combat-capable Grey Matter, but unlike Fasttrack, he averts Replacement Scrappy by being a hilarious little Heroic Comedic Sociopath.
    • Ultimate Echo Echo is considered such among the Ultimates, as he has the most unique design (also one of the few that isn't a Palette Swap with additional features) and a cool voice.
    • The Andromeda Five, both the original aliens and the forms Ben got from their DNA, were rather well-received by fans for their creative designs and developped personalities.
    • Aggregor, see Evil Is Cool below.
  • Evil Is Cool: Aggregor generally is considered one of the best things that came out of this show amongst the fans. Many were genuinely disappointed when Derrick J. Wyatt said he had no plan to bring back the character in Omniverse.
  • Evil Is Sexy:
    • Aggregor is the first Ben 10 Big Bad to not be a hideous monster and actually be reasonably attractive, with long hair and an open shirt too.
    • Also, Hive Elena. A very dangerous version of Raven Hair, Ivory Skin.
  • Foe Yay:
    • Darkstar, as usual, has this for Gwen.
    • Ultimate!Kevin's dialogue with Ben, in the beginning of the season finale, sound completely wrong taken out of context.
  • Franchise Original Sin: The next series gets a lot of complaints about overt focus on first-series continuity, Pandering to the Base, and script-recycling. This series seems to have had those problems before Omniverse, given the almost suspicious abundance of first-series elements, such as an appearance by one-off Zombozo, a storyline involving a Kevin who is a composite of Ben's aliens, as well as a guest appearance by the original, 10-year-old Ben, indicating that the next series only heightened these flaws.
  • Growing the Beard: If you consider this show another season rather than a separate show. Ultimate Alien had a clearer idea where it wanted to go with its first arc, filler episodes were not half as frequent as they were in Alien Force, and managing to strike a clean balance with Ben's personality. Season 2 would be far less lucky.
  • Harsher in Hindsight:
    • In the episode "Revenge of the Swarm", Ben and the others find out from a janitor that Elena's father had died. Kevin asks if he's telling the truth, the janitor replies "Anyone can die anytime". Wouldn't you know around the same time the episode aired Dwayne McDuffie passed away?
    • Also, Jennifer Nocturne developed Stockholm Syndrome, even to the point of having feelings with Carl Nesmith (Captain Nemesis). Five months later, Kristen Stewart, whom Jennifer Nocturne is an Expy of, cheats on Robert Pattinson, having a brief affair with director Rupert Sanders. Boy, did the show predict what would happen to Kristen Stewart...
  • Hilarious in Hindsight:
    • It's revealed in The Forge of Creation that Alien X was locked and one of the reasons was to prevent other characters like Albedo from accessing it in case they got hold of Ben's Omnitrix. Then come Ben 10,000 Returns, when Paradox explains an alternate universe where Albedo did use Alien X, only to stay motionless for a year.
    • When asked if Zombozo would return, Dwayne McDuffie said "not if he knows what's good for him". One of the first villains confirmed for Omniverse is Zombozo. Looks like he doesn't know what's good for him.
    • Will Harangue basically is a Jonah J. Jameson Expy, the only real differences beside his look being that he is an anchorman instead of a newspaper director and is pursuing Ben, a character created by Man of Action, instead of Spider-Man. A few years later come Ultimate Spider-Man, which Man of Action is working on... and where Jonah J. Jameson is portrayed as an anchorman instead of a newspaper director.
  • Ho Yay:
    • Parodied with Clone Ben and Kevin in a car in "Duped".
    • Arguably Cash and J.T. in "Reflected Glory". How many times did they have their arms around each other again?
    • Ben and Kevin again in the season finale ending "Absolute Power". The two have their little reconciliation, Gwen steps in to ask who wants to go with her to explain to her parents about their destroyed house, and Kevin promptly asks Ben if he wants to go to Mr. Smoothie with him. The two walk off together; cue credits.
    • Gwen and Charmcaster in "Where the Magic Happens".
      • And again in "Couples Retreat", where Gwen rags on Kevin for failing in his boyfriend duties all episode, and is a lot more emotionally invested in saving Charmcaster from being used by Darkstar. Ah, another good ol' Ben 10 Relationship Writing Fumble!
  • It's the Same, Now It Sucks: There were some complaints that it was too similar to the previous series, due to sharing the same general tone, artstyle, and format.
  • Jerkass Woobie:
    • For some viewers, Gwen's cousin Sunny became this by the end of the episode she appeared in due to Grandma Verdona vocally favoring Gwen over her right in front of her!
    • Charmcaster, once her backstory is revealed and then escalating with each passing appearance.
    • Come the twist ending of "Night of the Living Nightmare", if Albedo wasn't in this territory before, he certainly is now.
  • Magnificent Bastard:
  • Memetic Mutation: Kevin's infamous "When two (X) love each other very much..." sentence.
  • Moral Event Horizon: Alot of dark stuff happens in this show, but one case is unanimously agreed upon: Captain Nemesis becomes the first successful hands-on murderer in the series. He kills several people, including a random motorist just to steal his car. Even his Pet the Dog moment at the very end doesn't bring him back across the line.
  • Nightmare Fuel:
    • Surprisingly, Ultimate Echo Echo can come across as this. His "Sonic Doom" attack - in which his sonic discs duplicate to surround an enemy and trap them in a chamber of intense sound waves - is the only one of Ben's attacks specifically designed to kill someone. His cold, emotionless robot voice doesn't help either.
      Gwen (referring to her plan to return Ultimate Kevin back to normal instead of killing him): "Ben, you promised we'd try it my way first!"
      Ultimate Echo Echo: "Yeah... I lied." *pushes Gwen away*

  • Replacement Scrappy:
  • Rescued from the Scrappy Heap: This show's version of Eon was generally better-received than the movie version. For some reason, Derrick J. Wyatt still decided his episode to be non-canon.
  • Ron the Death Eater:
  • The Scrappy:
    • Intentional or not, Will Harangue sometimes overplays this, due to his tendencies to get out of punishment scot-free, behavior that contradicts his own self-professed ideals, and generally just being a Jerkass through and through. Him siding with alien invaders in the next series just because they got rid of Ben likely hasn't helped him.
    • Despite undergoing Character Development, Julie has once again began to become this, due to her having to Take a Level in Jerkass due to her unable to stand Ben's fame going into his head, breaking up with Ben the first time as a result before getting back together with him (and then breaking up with him again in the Omniverse series) before finally joining an evil cult that she thought was a charitable service and even initially refusing to listen to Ben when he suspects the cult of being evil. As a result, her Omniverse appearances, which were her last appearances in the Ben 10 franchise, have been nothing more but a Take That, Scrappy! to the character.
    • Trumbipulor didn't exactly impressed anyone during his small appearances. Most fans agree Omniverse did a mistake by bringing him back later.
    • Fasttrack is one of the less popular aliens, being viewed as a inferior replacement to Ensemble Darkhorse XLR8. He ends up being Put on a Bus in Omniverse.
  • Seasonal Rot: The second season...hasn't been very well received. Possibly due to head writer Dwayne McDuffie dying during the production, it had too many fillers, which were either standalone episodes with incredibly silly plots or overly dark side story arcs with no satisfying conclusion, both making a jarring contrast and preventing a focus on the actual main plot. The mainplot itself took a lot of time to come up (it wasn't even initiated in the first episode of the season!), and was criticized for being excessively grimdark and convoluted.
  • Squick:
    • No matter how "randomized" her DNA is, it can be a little unsettling to notice how much Eunice and Gwen favor... or worse, how she and Ben resemble each other. Or, for the Ben/Gwen shippers, she could be a dream come true.
    • Hive Elena's offer to be more like Gwen as a girlfriend if that will make Ben happy.
  • Strawman Has a Point: Despite being called out on it both In-Universe and out, Ben was actually doing the right thing in his decision to kill Kevin. Considering that Ben with Kevin's help couldn't even defeat Aggregor and Kevin has essentially become a much more powerful version of Aggregor, it is understandable why Ben viewed Ultimate Kevin as a much more genuine threat than his previous foes. While villains such as Vilgax and the Highbreed had a much more lasting effect, Ben was still able to defeat them at nearly every turn. Inversely Aggregor was able to defeat Ben's team at every turn and even manipulated them into helping him. Even his defeat came at great personal cost so its understandable to see why Ben is treating Ultimate Kevin much more seriously despite Kevin lacking Aggregor's intelligence. As Absolute Power showed, once Kevin had his fill on revenge, he moved onto gaining more power (via absorbing and nearly killing Alan and was stated to have done the same to the rest of the Plumber's Helpers). which undoubtedly would lead to Kevin eventually making his way to the Forge of Creation and absorbing the Celestialsapien baby, this time without the adequate firepower to stop him. It is also particularly notable how Ben doesn't actually try to put Kevin down until he endangered an entire space station of innocent students for the sake of killing Argit. Yes, Ben may have been out of line when considering putting Kevin down after Kevin had only really tried to murder an officer who obviously had it coming but bear in mind, that he is only considering it. As Kevin's crimes get closer and closer to crossing the Moral Event Horizon Examples , Ben starts to get more desperate and less willing to find plans that might stop Kevin and turns to plans that will stop the threat he poses. As Alien Force showed, the only methods to reverse his mutation was through the Dominus Librium (which Ben did not know was still functional) and destroying the Ultimatrix which would have disastrous consequences if it failed (via removing another potential method to stop Kevin). Its only when Ben actually starts fighting to kill that he can actually stop Kevin and in turn Aggregor. So while Ben nearly did cross the Moral Event Horizon,he was ultimately doing the right thing in doing so.
  • Tear Jerker:
    • The fate of Victor and Elena Validus. Turns out Victor died offscreen in an experment and that the Hive used Elena as a secondary Queen to survive, making her believe everything they do is just what she wants them to do and she's in control. Ultimately, unable to allow Ben's death, she manages to regain control and kill herself along with the Queen. What makes it even more of a Tear Jerker is that The Stinger reveals it was in vain as the Hive survived.
      • Less of one now—Turns out Elena somehow survived too and is even crazier. She brought two buildings to life to try and kill Kevin when he got too close to figuring out she was impersonating Julie.
      • Less of one or MORE of one? Death is probably preferable to madness.
    • "Prisoner 775", everything about the title character in general. The worst part is when he breaks down at the end and begs Ben to put him out of his misery and let him rejoin his dead family.
    • Charmcaster's crying moments in "Where the Magic Happens", "The Enemy of my Frenemy", AND "Couples Retreat". Charmcaster's character arc was depressing to a ludicrous degree, especially since it was left unfinished and she's left alone.
    • The ultimate fate of Kwarrel, the prisoner who taught Kevin to control his anger.
    • In-universe, Kevin attacking Gwen and then holding off for what they had, in his words causes her to cry for the first time in the series.
    • In "Ultimate Sacrifice" Ben was going to die willingly so that some of his Ultimate forms could escape the Ultimatrix and be free.
    • Jennifer Nocturne's backstory in "To Catch A Falling Star".
    • In "The Ultimate Enemy", Old George's death.
  • They Changed It, Now It Sucks: Just like fans of the original series had this reaction toward Alien Force, there are a good number of Alien Force fans who hated the changes made in this series.
  • They Wasted a Perfectly Good Plot: Most of Ben's pre-Alien Force aliens appear in the intro, seeming like they're going to set up appearances for them... But almost none of the aliens in the intro, some of which being very popular aliens, never actually appear in the series. Very odd, considering that one such alien, Articguana, actually did get a toy.
  • They Wasted a Perfectly Good Character:
    • Old George was a fairly well-received character, with an intriguing air and mystery to him, but he dies before we can learn much more about him or his backstory, including the question of how he's immortal.
    • Also, many people feel that Charmcaster's Face–Heel Turn in "Enemy of My Frenemy" was unnecessary or poorly written, and worse, she's left stuck in the Heel–Face Revolving Door afterwards and her storyline is then left unconcluded by the end of the series. While Omniverse did continue it with Charmcaster being less depressed and steered her into a more positive direction at the end, it needed to apply Broad Strokes retcons to it in order to do so.
    • Eon being a future Alternate Self of Ben is barely touched upon, despite all the potential for drama and stories it had. We don't even learn how he became evil.
  • What an Idiot:
    • Ben deciding that Kevin needs to die in order to stop him is arguably this, as Ben makes almost no effort to resolve the situation peacefully. One attempted murder on a guy who obviously had it coming (before this it had been brutal beatings and they had apparently never caught up until this point), and Ben's all for killing him.
    • The reasoning behind Charmcaster's Face–Heel Turn in "Enemy of my Frenemy". Seriously, Charmcaster? You think your father would WANT you bringing him back to life at the cost of 600,000 living souls?
    • Darkstar in "Couples Retreat". You can't remember a four-letter word? Really?
