History Fridge / Ben10Omniverse

* Big Chill being redesigned to be larger and more muscular suddenly makes a bit more sense when you realize that his name is [[JustForPun Big]] Chill.

* Omniverse takes place no more than a few weeks after the end of Ultimate Alien. The fact that nobody talks about the fact that they were all changed into Esoterica against their will implies that they have no memory of the event.

*** [[spoiler: Omniverse tends to Flanderize some aspects of the show, such as the Omnitrix's time outs, and Ben's intelligence level. Honestly, with this theory of Azmuth being this much of a dick, he's probably a much nicer guy then how he could've turned out in the show.]]

* More Fridge Heartwarming; at the end of the Showdown 2-parter when Ben asks if Azmuth is going to thank him and Azmuth just gives a sarcastic comeback. Sound's like he's being a Main/Jerkass, until you consider his words. "You expect me to put on some humiliating display every time you save a planet or two? Who has that sort of time?" In other words: "If I thanked you every time you pulled off a major feat of heroism I'd never get anything done." It's Azmuth's way of complimenting how much good Ben does for the universe while maintaining his usual level of aloofness.

* Attea’s plan may not make perfect sense at the end of the Frog War arc. It seems quite obvious that her hatred of Ben is very much genuine, noticeably when she went out of her way to fight him multiple times with Milleous not even present. However, if one were to connect all the possible implications, [[FridgeBrilliance it kinda starts to work]]. When Attea was hunting down Ben in “The Frogs of War: Part 1” she actually wasn’t trying to kill him, rather negotiate with him, willing to temporarily put their differences aside to help conspire against and defeat her father Milleous. Once he was disposed of, she was likely going to [[ChronicBackstabbingDisorder betray Ben and try to eliminate him and his friends as well]]. However, once she saw how handsome Ben’s Incursean form was, she decided to spare him, lying about her original ulterior motives, and was content enough with Milleous out of her way.
* Why do Ditto’s powers work differently here than in the original series? Simple, this is the new and improved Omnitrix, and it would make sense that it would remove some of the alien’s [[WeaksauceWeakness huge flaws]], or at the very least, make the transformations more practical. Case in point, the life/pain link between the Ditto clones is now phased out.

** He could also be alluding to Kevin, who did turn into Upgrade during "Framed" in the Classic show.
* Why do Attea and Looma seem to enjoy fighting Ben over the remote in “Catfight”? The answer may be more simple than you think. Because both Tetramand and Incursean cultures have an established affinity for violence/war, it would make sense that Ben trying to beat them up for the form-changing device would come off as romantic by their standards. It also helps further detail the plot of the episode: because both of them want to marry certain aliens (Bullfrag and Four Arms), they not only get to choose his respective alien forms, but also get the thrill and attention they want by forcing a worthy male opponent to chase a respective girl.
** Matt Wayne has confirmed this for Attea. While Bullfrag is still Attea’s favorite, she is nonetheless aroused when Ben in general is “conquering” enemies on major scales.

* In the episode "So Long & Thanks for the Smoothies" the universe is destroyed thanks to the Annihilaarg. Ben then copies the universe and everything continues as normal except he has a stylin' new jacket. The horror kicks in once you realize that this universe is just a copy. All the characters we've grown to know and love are all dead and the ones we will be viewing from now on are just a bunch of glorified clones.

* The implications behind the EsotericHappyEnding of ''Frogs of War''. So [[DaddysLittleVillain Attea]] [[spoiler:is in charge of the Incursean Empire]], now? [[NiceJobBreakingItHero Congratulations, heroes]]: you just [[spoiler:unleashed in the Galaxy a PsychopathicManchild over a GalacticConqueror in charge an empire with the required technology to blow up planets just by drawing switch]]. [[SarcasmMode Sure this will go well for everybody]]...

* This show and Ultimate Alien all take place in the same year, and likely not even in an entire 12 month period. Considering everything that happened in both shows (up to and including two Kevin mutations, the universe blowing up, a former personal hero turning evil, a relapse of his fear of clowns, nearly killing himself after his Ultimate Forms try to kill him, etc), one has to wonder if Ben's odder behaviors in Omniverse are because something in Ben ''cracked''.
* Albedo is able to turn into ultimate aliens without having to turn into their normal forms first. Had Alien X not been locked from the Ultimatrix during Double or Nothing (as Albedo can only turn into the aliens that Ben had unlocked during that episode) Albedo would have been able to turn into Ultimate Alien X without having to first deal with Serena and Bellicus.

* During the Duel of the Duplicates arc Albedo was able to turn into ultimate aliens without having to turn into their normal forms first. Had Alien X not been locked from the Ultimatrix during Double or Nothing (as Albedo can only turn into the aliens that Ben had unlocked during that episode) Albedo would have been able to turn into Ultimate Alien X without having to first deal with Serena and Bellicus.

** While it's not much better according to WordOfGod Vaxisaurians wear armor that resembles their ultimate selves and that was what Khyber was displaying rather than the one Ultimate Humungosaur in existence.

** Regarding contractions being the equivalent of Revonnahgander swearing, in "Rook Tales" Rook's siblings and even Ben are shocked that he says "you're staying here!" as it shows how angry he is with Master Kundo for assaulting his father and pursuing his sister. From a Revonnahgander perspective, Rook Blanko just used a PrecisionFStrike!

* Ghostfreak returns in this series, now in Ben's complete control. He also got a redesign, complete with shackles around the Omnitrix. At first you'd think this was just to make him spookier like all the other Ectonurites shown, but then you realize this form isn't Zs'Skayr. This Ghosftreak is 'bound' to the Omnitrix.

* The fact that the recreated Ultimatrix appears to possess both a master control and the ability to switch from ultimate to ultimate makes sense when you consider how it works; it is ''not'' the source of Albedo's transformations, this remains the work of the genetic alterations he made to himself in Ultimate Alien, the recreated Ultimatrix simply stabelizes his DNA, allowing him to remain in any chosen alien form he wishes, as such there is no need to route it all through his human form. Meanwhile however the evolution function worked on the original Ultimatrix in the recreated Ultimatrix it clearly evolves the active DNA, so when Albedo transforms, the Ultimatrix simply evolves the new DNA.

** Regarding contractions being the equivalent of Revonnahgander swearing, in "Rook Tales" Rook's siblings and even Ben are shocked that he says "you're staying here!" as it shows how angry he is with Master Kundo for assaulting his father and pursuing his sister. From a Revonnahgander perspective, Rook Blanko just engaged in BreakingPointSwearing!

* You can't really blame Chadzmuth for never having attended Intergalactic High Court prior to the series. Besides the likely hellish law school he went to taking much of his youth, give or take the galvan intelligence, such an event is probably once in a millennium perhaps even rare: What kind of crime would be so terrible it'll require every living being in the whole universe? Since neither the Highbreed, Vilgax or Maltruant have triggered one they're either that good to cover their legal tracks or the Intergalactic High Court is under a massive GodzillaThreshold reserved for the absolute worst crimes imaginable. Little wonder Chadzmuth predicted it'd end up as an {{unishment}}, he'd probably compare it to getting tried in Supreme Court for jaywalking if asked to elaborate.
** Why would the there be a raffle for being part of the voting pool with a prize of [[spoiler: owning your very own star]]? To motivate enough of the universe to actually participate in the trial, and why have a [[spoiler: star]] as the prize? Because as impressive as it sounds, there are billions of [[spoiler: stars]] in the Milky Way alone, so it's actually one of the cheapest prizes the Court ''could'' give away while still impressing the lucky jurist that won.

* Some have wondered about why Ben 23 has alien forms that shouldn't have been avaliable to him based on his scope and time scape, like Toolboxx (Armadrillo) and Teeny Weeny (Nanomech). However there is a possible source for those forms: Ben Prime. The Omnitrix's may have synced up at some point, leading to them adding aliens to each other that they didn't have originally. Omnitrixes have synced up in the series before.

* The fact that the recreated Ultimatrix appears to possess both a master control and the ability to switch from ultimate to ultimate makes sense when you considerhow it works; it is ''not'' the source of Albedo's transformations, this remains the work of the genetic alterations he made to himself in Ultimate Alien, the recreated Ultimatrix simply stabelizes his DNA, allowing him to remain in any chosen alien form he wishes, as such there is no need to route it all through his human form.
