- Author's Saving Throw:
- Making Julie a member of the Plumbers and an Action Girlfriend was done to make her feel like less of a Satellite Love Interest.
- Instead of simply ignoring Anodites like Omniverse, the author decided to give Verdona and Sunny Character Development 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.
- Base-Breaking Character: Valkyrie, primarily due to being a case of Gender Bender 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 Gender Bender comes across as more likely than you think.
- Better Than Canon: Most people seem to agree that, despite the occasional spelling and/or grammatical error, this series as a whole is much more enjoyable than Omniverse due to maintaining Ben's Character Development from previous sequels, toning down the Denser and Wackier tone and better exploiting the various story elements.
- Broken Base: 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.
- Author has taken the concerns into account and has said he has a set amount now.
- Character Rerailment: Vigax is back to the nigh unstoppable fighter he was in the original series.
- Fan-Preferred Couple: 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.
- Rescued from the Scrappy Heap: The author likes to do this with just about every scrappy from the canon shows. Even Nyancy Chan is turned into a credible threat.
- Ron the Death Eater: Downplayed with Herve, Julie's boyfriend from Ben 10: Omniverse. 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.
- Unexpected Character: Prisoner 775, named Valrean, appears as a prisoner in the Plumber HQ. as well as some other characters such as one of the Great One's former followers and some other minor characters making appearances.
YMMV / Ben 10: Guardians
