History YMMV / Ben10Guardians

* BrokenBase: The multiple addition of new aliens for Ben to almost each episode. Some have voiced concern that there may end up too many of them, and the writer might end up so focused on adding new aliens he'll forget to flesh out the ones already there. Others like the new additions.
** The author has taken the concerns into account and has said he has a set amount now.

** Walkatrout was made more likable by giving him enhanced swimming and biting capabilities.

* SugarWiki/BetterThanCanon: Most people seem to agree that, despite the [[RougeAnglesOfSatin occasional spelling and/or grammatical error]], this series as a whole is much more enjoyable than Omniverse due to maintaining Ben's CharacterDevelopment from previous sequels, toning down the DenserAndWackier tone and better exploiting the various story elements. Some notable examples include:
** Making Julie a member of the Plumbers and an ActionGirlfriend was done to make her feel like less of a SatelliteLoveInterest.
** Instead of simply ignoring Anodites like Omniverse, the author decided to give Verdona and Sunny CharacterDevelopment to make the race more likable.
** Osmosians are stated to be a mix of mutant human and alien.
** Attea is established as being 12 when she first met Ben, she was just short for her age and she is currently 15, likely to avoid the {{Squick}} that was caused by her crushing on Bullfrag in canon.

* BetterThanCanon: Most people seem to agree that, despite the [[RougeAnglesOfSatin occasional spelling and/or grammatical error]], this series as a whole is much more enjoyable than Omniverse due to maintaining Ben's CharacterDevelopment from previous sequels, toning down the DenserAndWackier tone and better exploiting the various story elements. Some notable examples include:

** Vigax is back to the nigh unstoppable fighter he was in the original series.

* AuthorsSavingThrow:

* BaseBreakingCharacter: Valkyrie, primarily due to being a case of GenderBender for Ben. Some fans argue this shouldn't be possible, due to the Omnitrix maintaining the owner's gender, and the excuse to justify her being an exception is flimsy; others don't care, and enjoy her as an unique alien. It should be noted that Necrofridgians, like Big Chill are genderless, so Valkyrie being a GenderBender comes across as more likely than you think.
* BetterThanCanon: Most people seem to agree that, despite the [[RougeAnglesOfSatin occasional spelling and/or grammatical error]], this series as a whole is much more enjoyable than Omniverse due to maintaining Ben's CharacterDevelopment from previous sequels, toning down the DenserAndWackier tone and better exploiting the various story elements.

* FanPreferredCouple: The author prefers Ben and Julie together, and as such they're the main couple in the fic.

** Author has taken the concerns into account and has said he has a set amount now.
* CharacterRerailment: Vigax is back to the nigh unstoppable fighter he was in the original series.

* FanPreferredCouple: One of the most prominent alterations is that Ben and Julie are still a couple, which stems from the author's favouritism towards the couple over the ones introduced in the show.
* RescuedFromTheScrappyHeap: The author likes to do this with just about every scrappy from the canon shows. Even Nyancy Chan is turned into a credible threat.

* RonTheDeathEater: [[DownplayedTrope Downplayed]] with Herve, Julie's boyfriend from ''WesternAnimation/Ben10Omniverse''. Instead of actually suddenly turning evil, Herve is merely a student photographer of French Origin who happens to support Harangue. However, he is justified in that he doesn't like the fact that Ben attracts supervillains, not so much a personal grudge against Ben. The two are still somewhat civil around each other.

* UnexpectedCharacter: Prisoner 775, [[NamedByTheAdaptation named Valrean]], appears as a prisoner in the Plumber HQ. as well as some other characters such as [[spoiler: one of the Great One's former followers and some other minor characters making appearances.]]
