Major Spells Used
Changes
Differences from canon
- Ben received the Assault Omnitrix instead of the final Omnitrix.
- Ben named his Talpaedan transformation Forge instead of Armodrillo.
- The Plumbers' origin on Earth happened differently, as explained in Foreverlasting.
- Carl Nesmith's Captain Nemesis was only a TV hero in this timeline, akin to Kangaroo Kommando.
- He did still become a very high-profile arms manufacturer and later super villain.
- Much of Omniverse did not transpire. Specific distinctions are mentioned throughout the series.
- Rook Blonko's partnership with Ben was much shorter, as will be partially explained in Can't Trust the Weather, Man.
- Where Omniverse erroneously continued with Ben still 16, in spite of too much time passing during Ultimate Alien, Back in Action proceeds with Ben instantly turning 17.
- Some of Ben's transformations have different appearances. Gwen's Anodite form also reprises its Alien Force/Ultimate Alien appearance.
- Grey Matter appears with his Omnitrix on his chest, as it would have had he appeared in Ultimate Alien. As of Hit and Miss, he has donned his Omniverse attire.
- Articguana, Buzzshock, and Stinkfly have their original series appearances.
- While Primus and the Codon Stream act as backups, the Hidden Universe acts as a local hub for transformations, housing all available transformations. In this timeline, the Hidden Universe was available in the original Omnitrix and Assault Omnitrix but not the Ultimatrix.
- All canon "mutant" characters are alien hybrids.
- Gwen's school is instead called Dwayne University, in honor of Dwayne McDuffie.
- Hex is not a Professor at Gwen's school.
Second Run retcons
- Originally in Ten Plus Twenty, it was suggested a presidential election was forthcoming (lining up with the real world upcoming 2012 election). To align with some upcoming content in Season 2, it was changed to reference the incumbent president and a forthcoming midterm election.
- Originally, Malevolence's patterns were green. To distinguish from Julie/Ken and Upgrade, this was changed to purple befitting his former royalty.
Trivia
- On YouTube, the show was referred to as Ben 10: Alien Universe Re-Animated.
- The logo was originally created by NickFusi0n.
- Every third episode is four parts. The premiere episode Infernosphere was first, followed by No Strings Attached. Plight of Pinocchio is next in line for this treatment.
