Y/n Tennyson is the third cousin in the family, living with Gwen after his parents, Mai and Azun, mysteriously vanished. Life was already a little weird-but nothing could have prepared him for this summer. When Grandpa Max takes Y/n, Ben, and Gwen on a cross-country vacation, things take a wild turn. Ben stumbles onto a strange pod containing a powerful watch... and Y/n just so happens to find another. Once those devices latch on, their "normal" summer break turns into an alien-smashing, villain-thrashing road trip unlike anything they imagined. Two cousins. Two watches. Infinite trouble. And together? They're about to make this the most unforgettable summer yet.

Ren tennyson is the assistant of Rick Sanchez. With the powerful Omnitrix watch as he helps Rick and Morty on their adventures....or at least try to minimize the damage. (This is my first story and not a professional writer. Feedback will be appreciated)

After transferring to a new school and city, Adam Michaels was taking a shortcut through the woods at night when he found a watch that allowed him to transform into 10 or more aliens. Join him, his grandfather Max Tennyson, and the superhero girls on many adventures and fight many villains and alien threats on earth or space.

Y/n L/n is a boy who lived a normal life. He had friends, a family that loved him and a gf that loved him as well. But unbeknownst to him, his DNA was not just human. But slmething else as when a meteor landed ina. forest he was close too, Y/n accidently activated a device that allow him to transform into many alien lives.

Ben Tennyson was abducted by aliens when he was 10 years old after accidentally received the Omnitrix, but then got rescued by Tetrax. He also brought Rook Blonko with his side. Both Ben and Rook are orphans, where Tetrax trained them to become the Galactic Guardians. Then after reaching his teen years, he received the Ultimatrix and recruiting more members.

Ben Tennyson, a seemingly ordinary fourteen-year-old boy, was granted immeasurable power from outer space. This power granted him extraordinary abilities that would catapult him into adventures of epic proportions, carrying the mantle of the universe upon his shoulders. However, his unexpected traveling companions don't entirely share that perception; they just want something more with Young Tennyson. This is a loose interpretation of the Ben 10: Chaquetrix AU, created by @TrixTheAlien on Twitter/X. You can find all the illustrations on my Twitter, @BlueWolfArtista.

In an unlikely rift between dimensions, Ben Tennyson's Omnitrix reacts to an unknown energy and opens a portal to... Hell. Catapulted into the chaotic and colorful universe of the Hazbin Hotel, Ben finds himself separated from Gwen and Kevin, with no immediate way home. Injured and disoriented, he is found by Charlie Morningstar, the princess of Hell, who welcomes him into her hotel with the idea of "redeeming" this mysterious human with strange powers. Ben, initially wary, agrees to stay alone to find a way back to Earth... but things quickly get complicated. Meanwhile, Alastor shows a disturbing interest in the device, while Angel Dust takes Ben under her wing (sort of), drawing him into the crazy dynamics of the hotel. Charlie, determined to prove that even Hell can change, sees hope in Ben: someone who fights for good, even in the most misplaced of places. Ben, for his part, begins to understand that not all "demons" are truly lost. But when a powerful infernal entity discovers the Omnitrix's potential and decides to possess it to unleash chaos across the worlds, Ben must choose: escape and return home... or stay and protect those who are no longer just "monsters." Through battles, sarcasm, emotional moments, and unexpected bonds, Ben becomes something he never imagined... "At your service, princess." A promise, a challenge... and perhaps the start of a new family in Hell.

When Ben Tennyson is sent into another universe during a confrontation with Vilgax, he suddenly finds himself in Paris, a city protected by two superheroes named Ladybug and Cat Noir. He then decides to lend them a hand while searching for a way to return home. Ben x Marinette

The Light thought they had created the perfect weapon. They murdered Nate Tennyson-one of Ben and Kai's legendary triplets-and replaced him with a programmed clone, bound to the Omnitrix. But secrets can't stay buried forever. When Nia and Liam Tennyson, alongside Ethan (the son of Kevin and Gwen), storm Cadmus, they don't just find a weapon; they find a family they thought they lost. But this Nate is different-coded for obedience and thrust into a world of heroes and conspiracies. Alongside a full-powered Conner Kent and a corrupted Supergirl rescued from the Light's grasp, this new generation of heroes must redefine their destiny. From the gravity-defying shots of Artemis to the shadow-bending legacy of Nightwing, the team faces a changing world. As time jumps, new faces emerge: a Chaos Witch, a Ghost Rider-infused Prince, and the biological wonder known as Eunice. In a web of cosmic beetles, runic magic, and high-stakes romance, the Team must decide if they are heroes by blood, or heroes by choice. "The watch makes him a weapon. His heart makes him a hero."
