Hey, everyone, just to let you know I do not Own Ben 10 or Mass Effect they are owned by their respected companies and owners.

This is my first fanfic Enjoy also takes place after Omniverse and starts on Horizon in Mass Effect 2

In a town called Bellwood lives a hero Call Benjamin (Ben for short) Kirby Tennyson. Everyone know who he is and what he does by turning into a bunch of different aliens from his wristwatch the Omnitrix. His cousin Gwen is a doofus but a powerful one as a magic wielding alien called anodite. Kevin, Gwen boyfriend is a Osmosian that can absorb metals /materials to make him harder and stronger, also he a fairly good mechanic. You also have Rook Blonko Ben partner in the plumbers a group of galactic cops that protect the peace. Rook is a steadfast loyal friend who long understands that they more to Ben than meets the eye. Then they Grampa Max the leader, the inspiration, the respect but that changes when Vilgax the conqueror Attacks for Ben Tennyson final time.

Galvin Prime

Asmuth "Get this to Ben, Myaxx NOW!".

Myaxx " You Stupid old Bug I'm no"

Asmuth "Vilgax is here and somehow he managed to get power beyond what he capable of storing within himself, and I don't have that long left so Myaxx for the love of Galvin just go and tell ben that this time they is an instructing manual. Goodbye Myaxx"

Myaxx Expression sours Heavily.

Myaxx "Bye you Old bugger"

Myaxx Leaves on the ship and escapes to earth evading Vilgax fleet and on coming fighters that chase after her.

Asmuth "Goodbye Ben Tennyson. I hope paradox know what he doing".

Vilgax Manically laughs in the background destroy Galvin once and for all.

Vilgax "Your Next Ben Tennyson"

Earth/Bellwood

Ben " I love Mr. smoothy but I wished everyone else was here man it sucks"

Myaxx "Beennnn"

Ben Turns around to see Myaxx Injured bleeding from the waist down "Myaxx what happened here let me try and hel…."

Myaxx "No time take it "cough cough" and Goodbye Ben" Myaxx Hands the device to Ben and finally collapses.

Ben looks at the Myaxx given her one final respect, then proceed to return to the table opening the device. Inside was another Omnitrix but the design is close to the origin with some Morden updated features and styles. It black with green pipeline around and it also has a flat button like his white one he wearing now. Ben Takes hold of the device and it straps on to his wrist like a symbiont attached to it host, it combines with Morden one big Ultimate Omnitrix. The Omnitrix lights up.

Asmuth "Ben if you listen than that means Galvin is Dead and I along with it"

Ben straights up now standing not caring that everyone is staring, He use to that anyway. He worries, water streaming down his face like a rainforest "No"

Asmuth "Ben on your wrist contains the final Omnitrix, with Master control included, but you do have an energy output when using your aliens so don't go getting a bigger ego than what you already have. I also included a instruction manual as well to help understand the different energy levels each aliens have.

Ben just watching horrified that his mentor is dead, his friend dead!

Asmuth " Ben Vilgax will attack and he will kill your loved ones, Goodbye Ben Tennyson and might I say Good luck"

Ben just stands blank face, looking at the device now back to Myaxx, now up in the sky. " I need to warn the plumbers and everyone" in a serious way that ben rarely Been before. Ben hits the device, a green glow appears blinding everyone around and then becomes Fasttrack, a blue and Black Furry Speedster with a lightning blue bolt in the middle.

…. Time Skip 2 Years…..

Gwen " Ben Vilgax has….."

Ben "what is it Gwen, GWEN!

Ben Turns around in his Atomix form wearing a green and white armor, while also showcase green energy. Hearing Explosion sound in the background. Boom! Crack. Earth was cracked. "NO. GWEN, KEVIN, ROOK, GRAMPA, MUM, DAD, KAI." Ben Anger Surges " VILGAX!"

Earth gone, home gone, his friends and family gone

"Ben Ben Tennyson"

Ben/Atomics sees he Reiny but also the army Ben has bult up to fight back. Petrosapien, Highbreed, plumbers, even Galvanic Mechamorph (plus ship) are here because of they destroyed creator " what is it Reiny"

Reiny responds with a apologetic glance "we got out as many as we could Ben but your family, I'm sorry Ben Ben Tennyson"

"BEN!"

Ben turns again to see ultimate humungousaur the same one that escape from the Ultimatrix "we struggling fighting back Vilgax forces, You need to end vilgax now"

Ben look down in thinking crossing his arms in hopes. " Ult Humungousaur, get your Ults and help Reiny with getting the humans out of this sector and into the new planet we found." Both Nod. Tetrax Do you read"

Tetrax Response, "I'm Here Ben, I'm so sorry I..."

Ben/Atomics " No time, I'm ending Vilgax once and for all. I need you to look after new earth for me because I won't be coming back"

The air is silence….

Tetrax "you're sure"

Ben/Atomics confident in his answer "Yes"

Tetrax hums "good luck my friend" Coms cut Ben/Atomics hits The Omnitrix that on Atomic Chest and Turns into Alien X

As Ben approaches Vilgax Dreadnought with full agreement from both Serena and Bellicus as you find that quite rare but the power vilgax has well made the Celestialsapien quite unhappy and that an understatement . Ship approaches "SHIP!, SHIP!"

Ben/Alien X "Hello Ship and happy you want to help but you need to leave with the others"

Ship Goes full Ship "SHIIIIIIIIIIIIIIIP!" Ship hanger doors open revealing Julie.

Ben/Alien X "Julie what are you"

Julie " Ben please take ship with you, Tetrax explains through the coms of what your planning and you should not be alone after what happened" Julie Turns to see the destroyed earth. The silence is quit once again.

Ben/Alien X "Okay Julie but I am going to teleport you to the Highbreed carrier ship so you can join then in New earth" Julie Nods Appreciatively and smiles "thanks and sorry Ben it been a fun ride you immature prat"

Ben/Alien X nods "Motion Carried: Transport Julie to Carrier ship" Julie was gone but not forgotten. " Let go ship" Ship jumps about in space excitably.

They head to Vilgax ship and smash they way through the corridors fight after fight defeating foe after foe. reaching the throne room Ben/Alien X in his triplet voice echoes "VILGAX!. I'm Here to destroy you once and for all"

Vilgax Laughs "so you fight at full strength straight away very smart for Child! This power I stole from the Celestialsapien has made me a god and you think that you and that pathetic excuse of Galvanic Mechamorph can beat me"

Ben/Alien X " Motion Carried: Eradicate Vilgax once and for all. Ship Hold on tight" Ship does so "ship" in a quit murmur.

Vilgax eyes Bulged out not thinking Ben 10 would fully eradicate him "WHAT! You realized that if you eradicate me than you yourself will as well. Ben/Alien X nods "I know Vilgax!" with some spit in his voice. "why do you think both Serena and Bellicus agreed to my plan and gave me full control" Vilgax for once in his entire Existence feels quite nervous and may have finally truly push Ben 10 to the edge. He looks at his Tendrils arms disintegrating from Existence but the same came be said about Ben 10, Ben/Alien X " One must make scarifies to win Vilgax, you taught me that and, and using all of alien X power to get rid of you and your, Celestialsapien powers, well it worth it I say. This is not a fight, this is me being push to the edge you created"

Vilgax Smiles and sites back down on the thrown while a grow light takes his, Ship and Ben bodies for good " Goodbye Ben Tennyson and for once you been a worthy adversely if not childish"

Ben/Alien X "Goodbye Vilgax and Goodbye everyone" Everyone watches Ben go from existing to non-existing ending vilgax as a threat once and for all.
