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

Helen's eyes settled on D'Void's smile.

Tensing, Manny then ran by Helen prior to a handful of Null Guardians pursuing them. They were barely able to avoid their fangs as the Null Guardians snapped at them.

Manny started to tense as soon as D'Void appeared in the doorway of the citadel. He loathed the sight of the latter's smile. The sounds of multiple Null Guardians screeching. Viewing the Null Guardians flying from the citadel.

All he had to do was say one little word. Paradox/Eon

Eight years after the original series, the Tennysons go on their final Summer trip. The events of Alien Force and beyond will not be in this story, but some elements will be used.

It started with an alien device that did what it did. It stuck itself upon his wrist with secrets that it hid. Now he's got super powers, he's no ordinary kid. He's Ben 10! My retelling of the Ben 10 series, with various changes throughout the story, including: mild cursing, some mild violence, skipped and altered episodes, etc. Find it, Titans: Elemental and other stories on AO3!

What will happen if instead of Alan giving off the GPS signal, it was a young runaway that is more than what she seems? Follow the adventures of Vanessa Cunningham, her little sister Sabrina, her new boyfriend Ben, and her new friends Gwen and Kevin as they go on an action-packed adventure to stop the Highbreed Invasion!

After "They Lurk Below" Eddie Grandsmith joins the Tennysons on their summer road trip.

(Fem Ben) Jen Tennyson is told a harsh truth. What happens next?

Ben is driving a while after the final battle in Ultimate Alien and ends up in a portal to another world. Ben doesn't get the new Omnitrix due to Azimuth not finishing it yet. Ben now is on a new mission to help this world where he was killed by the Omnitrix as a 10 year old and his cousin getting it. Not a Ben X Gwen 10 Plumber Officer Benjamin Kirby Tennyson. Gwen 10: Alien

The sequel series to The Night I beacame Ben 10. Now, ALIEN FORCE STYLE! New aliens, new teammates, new story, new powers, blah blah blah... OC/OC. Gwen/Kevin. Ben/OC. Cover made by Omnitrix1.

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.

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.

Gwen enters into a world of vore where she's in various one shot situations involving herself being eaten alive in erotic fashions. Vore, Lemons, Yuri, Breasts and butt growth. Futa Transformation. Genderbending. Alien sex. Feel free to give suggestions.

(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.
