Benjamin Tennyson is a 10 year old boy who on one summer road trip with his Grandpa, finds a mysterious alien watch called the Omnitrix.


This version is the original Ben from the original series. In my fanon Alien force, Ultimate Alien and Omniverse never happened, the series continues on forever from Negative 10.

Ben is a small 10 year old boy. He has brown hair and green eyes and a snarky attitude. Ben always wears a white t shirt with black rims on the sleeves, a black collar and stripe on the front. Green trousers, black sneakers and the omnitrix on his arm.

He travels across America for the summer vacation with his Grandpa Max and his cousin Gwen in their Grandpa's RV the Rustbucket. Ben and Gwen openly dislike eachother and quarrel often, they hate having to share a birthday. Ben and Gwen also dislike their Grandpa's cooking and penchant for living off the land, which usually means eating bugs...

Ben is often foolhardy and quickly gets himself in trouble not thinking ahead, his Omnitrix also times out at unfortunate moments or gives him the wrong alien because he hasn't unlocked the master code. Being a particularly immature human child he simply isn't smart enough to figure it out.

Having to rely on an omnitrix with a mind of its own and only in limited mode means Ben often gets into danger or captured.

Ben often (Especially in my fanon!) gets into distress and captured because I think it's funny especially if it involves gooey stuff, quicksand, alien tentacles and stuff. Lots of fetishy stuff happens to him!

Ben also often gets age regressed because I'm a real jerk! XD. As a baby he just wears a diaper and the omnitrix on his arm. Baby Ben like big shiny noses like Zombozos but is initially scared of clowns. Baby Ben is also really gross.



A red, very strong alien with four arms. Unfortunately with his immense strength he is also very clumsy and small delicate things are not suitable for him to use as his hands are too chunky.


Made of near indestructible diamond and can shapeshift his body into any form he can think of. He can for example, quickly grow a wall of diamond to shield himself, turn his arms into blades and shoot diamond shards at enemies. He can also deflect lasers. However sonic blasts can shatter him.


A fire elemental, controls fire in all its forms. However is extremely weak to materials that put out fire, i.e. Foam and water. A cold reverses his powers i.e. Ice powers instead of fire.


Can fly, has sharp claws, large enough to carry people and sprays slime from his eyes, this slime varies from an acidic and flammable compound that explodes on contact with fire to an immobilising jelly like goo. Ben likes the gooey part!


An aquatic alien that can breathe and swim underwater but is pretty useless on land as he needs to keep pouring water on himself.


A very small alien but very intelligent and can fit inside small places such as inside machines to dismantle them. However he is very weak and easy to capture. Ben also has problems with his new intelligence and sometimes doesn't understand what he just said.


A dog like alien with no eyes and nose. It uses sonar to see the world as sounds. It uses its gills to smell and taste things. It's also quite fast and quite strong and agile. An all rounder that makes up for the weaknesses of stronger or faster aliens. Colds block his gills so he can't smell anything.If he can't smell or sense sonar he is essentially blind.


A very fast moving alien with sharp claws and a long tail. He wears a mask for some reason. He can't run on slippery services and can get stuck in gooey substances.


A blob of nanobots that can upgrade any technology however, sentient machines are very difficult to control. Acids damages this alien. When not in possession of a machine, this alien can shoot lasers from its eye.

Greymatter's species created these when they accidentally left nanobots on their moon.


A ghost like alien from Ecto-Nurite, a very dark void. Ghostfreak can turn invisible, intangible and is very strong. Sometimes he can open his skin to show his true form that is said to be terrifying.

Unfortunately it's true form is extremely vulnerable to sunlight, which can incinerate it if exposed long enough. Also this alien has a mind of its own and won't listen to Ben. Ben explains that after returning to normal from this form he doesn't remember anything that he did as this alien meaning Ghostfreak was in complete control... Ben later gets nightmares from using this alien too much and becomes scared of it. Ghostfreak then escapes from the watch and goes rogue.


A new alien, it can roll up into an armoured ball and moves very fast after building up momentum. However outside its ball form it's clumsy.


A plant like alien, he can possess and control plants, throw grenade like pods, grow claw like thorns to cut through things and stretch himself to any length he disires as well as his vines to swing from things. However he is vulnerable to fire.


A werewolf like alien that fires soundwaves. Obtained from a werewolf like alien.


An Egyptian mummy like alien, can control its bandages like limbs to grab or tie up foes. Baby Ben seems to really like this form for some reason.


A Frankenstein like alien, has magnetic feet, doesn't need to breath at all and has electrical elemental powers from the powerpack on his back.


Can multiply himself into as many clones as he likes but if one gets captured they can't recall themselves together, trapping Ben in this form. Also they share pain with eachother so,if one is hurt they all feel pain. They are voiced by Yakko from Animaniacs.


A bat like alien with many eyes, he can shoot lasers from them and a big laser by combining his eyes together.


Can eat anything except actual food. Anything it eats it blast out again as explosive loogies. It also has four very long stretchy tongues for grabbing things and can eat things larger than himself. However he can't digest actual food.


The battery aliens from Tourist Trap. Can multiply and control electricity. Near unstoppable except by earthing them and trapping them in a giant lightbulb. As such rogue ones are dangerous.


As a human, Ben is pretty useless in combat (except for Greymatter...) however he has a hoverboard he can fly with which he got from Tetrax.

As a baby he is smaller and weaker but faster and more agile, Baby Ben relies on tricks and doing very gross things to distract foes.
