When Gwen is told Ben has a new girlfriend some time after a bad breakup with Julie, she is at first overjoyed but then becomes more than shocked as to who it is and refuses to accept that the relationship is real. Set one year after the finale of Ultimate Alien.

Vanessa Cunningham was expecting to go on a normal summer vacation with her childhood best friend and his family, but that all changed when an alien space pod crashes down on their campsite while carrying a pair of strange devices called 'The Biomnitrix'. Now Ben and Vanessa go on epic adventures of fighting supervillains, monsters, sorcerers, aliens, and all sorts of other things.

(This is an AU, it will be a mix of classic Ben 10 and the Ben 10 reboot.) Jen and Gwen Tennyson are both very aware that they are not alone in the universe. At a young age, both girls were introduced to aliens, magic, and other things like that. The girls understood these things well and Jen even awakened her alien power and the girls went on to live...somewhat normal lives.

Shortly after their thirteenth birthdays, first Gwen, then Ben had Hanahaki surgery. As expected, they stopped coughing up flowers, and they both lost whatever romantic longings they had that brought on the disease. Gwen still has memories of her feelings from before, though, and they never really knew why the other caught the disease. The doctors said it would never happen again

Unfortunately for him, Eon learns how to value life in the form of Percival Dachs. Paradox/Eon slash

Following their eventful night fighting Darkstar, Gwen pays Kevin a visit.

This is a lemon filled story which has a couple OC's with their own Omnitrixes as they go from planet to planet to learn more about various species of aliens... like Azmuth intended instead of the Omnitrix being a weapon... expect lemons galore and many crossovers too many to count as a crew on the Rust bucket IV travel the stars... inspired by various fanfics and other sources

The continued misadventures of Ben Tennyson and his friends, fighting against spiraling crime, ancient dangers, and rising villainy.

An alternate retelling of the Ben 10 universe under the perspective of teenage troublemaker Alex Mathers, armed with an Omnitrix, he’s willing to take on anyone and anything.

How will the duo react to the growing feelings betwixt them? Follow Ben and Gwen into adulthood as they explore their relationship! Bwen! Season 5!

We know how this old story goes, a 10-year-old boy goes out to a forest when a strange watch from space goes and attaches to his wrist. Well, this is much the same though his aliens are a little well...'different' this time around, also he doesn't become them but summons them as his new crime fighting partners!

I should've done this months ago, but it's my fault for forgetting. This is my earnest reaction to Power Master's Ben 10 True Omniverse Message, which announced the series' (now temporary) cancellation. The 2nd chapter covers additional topics that I couldn't cover in the 1st one, and a 4th one is about Power Master un-cancelling True Omniverse. Rated T for some coarse language

What started out as the worst summer ever turned into a strange adventure when a pod shows up carrying a weird girl and an even weirder watch. Now with the Omnitrix stuck to Ben's wrist and being hunted by Vilgax and his lethal 'children', this was definitely going to be an interesting summer.

What's better than having one little slut all to yourself? Having two little sluts all to yourself. (Lemon warning)

2 Años después de los sucesos en Omniverse, un viejo enemigo se alza, esta vez dispuesto a arrasar con quienes le pusieron contra las cuerdas años atrás, pero la interferencia e influencia de un nuevo aliado para nuestros héroes dará tiempo para forjar alianzas, algunas mas fuertes e intimas que otras. Un pintoresco grupo de héroes, antihéroes y villanos unidos contra un mal mayor.

The past is prologue, goes a saying. For Gwen Tennyson, this is about to be painfully true. OR: A tentative fix-fic for the Dagon arc of UA, entirely unbeta'ed.

It started when an alien device did what it did and stuck itself upon a wrist with secrets that it hid. But this isn't the story of some ordinary kid. Whose wrist does the alien device find itself upon? How will the device allow itself to be used? And what will become of it and its user? (A Ben 10 CYOA; Cross-Posted On AO3)

After their secret is revealed, Ben and Jen are moving on to new adventures with their new Ultimatrixes providing tons of new possibilities. Certainly going to be a help with the many dangerous trials awaiting for them.
