** The first episode establishes that any damage Ben suffers alien mode will carry back over into his human form. This is never brought up again, nor does Ben ever sustain any injuries after a tough battle, apart from getting a black eye in ''Grounded''.

** It is stated in the first episode that any injuries or wounds Ben suffers while he in alien mode will carry back over to his human form. Meaning he will be in genuine danger while fighting in this series. This is never brought up again, nor is Ben ever any worse for the wear after a tough battle apart from getting a black eye in ''Grounded''.

''Ben 10: Alien Force'' was a SequelSeries to ''WesternAnimation/Ben10''. Management was taken over from Creator/ManOfActionStudios by Glen Murakami and Creator/DwayneMcDuffie of the ''WesternAnimation/JusticeLeague'' fame.

This show as a whole is notable for starting a major BrokenBase in the Ben 10 fandom: while a lot of fans complained about the often unexplained (or badly explained) changes both in-story and amongst the characters, and remained faithful only to the original series, many others appreciated to see Ben finally getting mature after all the AesopAmnesia in the original series, as well as the CerebusSyndrome it led to. It's commonly believed that all of Alien Force was the highlight of the franchise. In the end, Alien Force was popular enough to last three seasons and allow the franchise to go on, spawning [[WesternAnimation/Ben10UltimateAlien a similar sequel]] before it was decided to try going back to the Original Series' roots with ''WesternAnimation/Ben10Omniverse''.

As with the original series, ''Alien Force'' was given a LiveActionAdaptation film ''Film/Ben10AlienSwarm''. General consensus is that it's leagues better than the original's ''[[Film/Ben10RaceAgainstTime Race Against Time]]'' whiles others were disappointing at the fewer Hero changes.

* AsskickingEqualsAuthority: In this series, this is an interplanetary law, allowing anybody who's powerful enough to beat the strongest person on a planet control over that planet. Vilgax conquers planets this way.

* ReformationAcknowledgment:

* ShipSinking: Most noticeably the show's infamous KissingCousins. Unfortunately, it didn't quite work out the way the writers hoped it would due to Gwen and Kevin falling in love pretty damn quickly for two characters who barely had any interaction in the original series, and when they did, it wasn't positive.

* EverythingsBetterWithDinosaurs: Humungousaur

* DiminishingVillainThreat: The Forever Knights ''were'' an ancient cult seeking alien technology to facilitate their world conquest. Now, it seems it started in trying to find tech to kill an alien dragon. This is fortunately corrected in ''[[WesternAnimation/Ben10UltimateAlien Ultimate Alien]]''.
** Vilgax received a new, physically less impressive design, and is defeated several times by Ben in Season 3.
** After being a big threat in her debut episode due to powerful magic and cleverness, Charmcaster returns in an alternate timeline in "Time Heals", constantly boasting about how she killed that timeline's Gwen...only to get [[TheWorfEffect kicked around by present-Gwen on multiple occasions.]] It leaves one with the impression she only managed to kill her timeline's Gwen because she got lucky.

** ''The Con of Rath'' introduces us to a new Omnitrix alien: a broad-shouldered, feral savage with a quick temper, razor-sharp claws jutting from his knuckles, and a tendency to solve everything with violence. [[{{Wolverine}} Sound familiar?]]

* XanatosGambit: Ben in the series finale. [[spoiler:After Vilgax successfully steals and activates the Omnitrix, Ben uses a voice command to set it for a 30 second self-destruct [[note]] (In the original series, it was charged for several days, which is why the explosion would wipe out the universe; 30 seconds would cause an explosion of a much smaller radius but still be deadly)[[/note]]. Vilgax either removes the Omnitrix and allows Ben to reclaim it, or the Omnitrix is destroyed. Vilgax choses the second option and gets his arm blown up. [[MadeOfIron He gets better.]]]]

* AesopAmnesia: Particularly blatant with Kevin, who learns in "In Charm's Way" that Gwen still loves him despite his new, monstrous appearance. A few episodes later, he's back to wallowing in {{Wangst}} about how Gwen must not care about him anymore due to him looking the way he does.

** At the end of the Highbreed invasion, Ben's omnitrix accidentally resets. He starts lamenting on how he can't recognize any of the aliens he currently has downloaded, but realized the new possibilities he now has with all new aliens. However, he has the same aliens going into season 3.

* MagicSkirt: Though Gwen wore tights, too, so even if her skirt were to fly up, we still wouldn't get a PantyShot.

** At the end of the Highbreed invasion, Ben's omnitrix accidentally resets. Ben starts lamenting on how he can't recognize any of the aliens he currently has downloaded, but realized the new possibilities he now has with all new aliens. However, he has the same aliens going into season 3.

* WhereTheHellIsSpringfield: Bellwood is apparently [[WordOfGod in the same state as]] [[TheSimpsons Springfield]].

* EverythingsBetterWithMonkeys: One of ben's aliens, aptly named Spidermonkey, resembles a cross between a monkey and a spider.

* PlotHole: A number of these have popped up in the series and usually come with a {{Retcon}}, but others aren't patched up. One example being Vilgax [[spoiler: getting the Omnitrix and being unable to use it. Even though in the first series he had extensive knowledge of the Omnitrix, even in the series finale of Alien Force he had better understanding of it than in the earlier episode.]]

* SameCharacterButDifferent: Pretty much everyone. The most drastic change is with Kevin. In the first series, he's an eleven-year-old sociopath who couldn't care less about crashing a money and passenger train together, killing hundreds of people for some cash. Then he's suddenly a love-struck teen and friends with Ben!? No amount of CharacterDevelopment could explain having a completely different personality...although [[WesternAnimation/Ben10UltimateAlien the next series tries its luck at it.]]
