Ben Tennyson was one of the greatest heroes ever, he had saved both the planet and the entire universe time after time. From a young age Ben had been saving the day from all manner of evil. Whether it be a mad scientist bent on transforming the world into his view of perfection or stopping an alien warlord who was bent on conquering the planet. Ben fought them all and beat them all, time and time again no matter the odds. He did this not only with help of his friends and family but with one of the most powerful devices ever created.
The omnitrix, a level 20 tech device created by Azmuth the first thinker of the Galvan race. The omnitrix was designed to collect and store the DNA of all the sentient alien life throughout the entire universe. It also allowed whoever wore it to transform into the alien species that the DNA came from. The only person Azmuth allowed to wield his greatest creation was Ben. Ben had proved himself time and time again to Azmuth, showing the alien genius that the omnitrix could be used as a tool to help people.
Throughout most of his young age, Ben wore the omnitrix and saved the day all the time. However Ben always wondered how smart the omnitrix actually was. He knew that it had an A.I that keep him alive if his life was ever in danger or he died. It could create a new body for him if his old one was destroyed, it transform into an alien that could withstand a brutal attack that would kill a normal person. The omnitrix also had many failsafes that would stop anyone who was foolish enough to try and remove the omnitrix from Ben's wrist.
The omnitrix was powerful and Ben knew that it's power and potential was limitless. Ben felt as though the omnitrix was constantly upgrading itself, constantly improving and becoming smarter. Ben would always ask Azmuth if this was true but the genius always pushed it to the side.
Eventually there would come a day that Ben would discover that the omnitrix could do something he never even thought of. It was that day that life truly changed for Ben and things would no longer be the same.
Bellwood
It was a day like any other for Ben, he and his partner Rook had just stopped another crime in Undertown and now they were enjoying one of Ben's most favorite beverages ever. A smoothie from Mr. Smoothies, along with some chili fries from the Burger Shack. Also, Ben's cousin Gwendolyn and his best friend Kevin had stopped by during one of Gwendolyn's breaks.
"I think that is one of the weirdest flavors you've had yet" Kevin said as he cleaned the hood of his car
"I always thought grasshopper and artichoke was" Ben said as he took a sip from his smoothie
"I don't know, I think guava and fish eggs takes the cake" Gwendolyn said as she petted Zed's head
"You guys are the weird ones here" Ben said as he took another sip from his smoothie
"I hate to have to tell you this Ben but while you complain about your grandfather's cooking and his taste in cuisine, you drink smoothies that are similar to what he cooks and eats" Rook says to Ben
Ben grew silent for a minute thinking about what Rook had just said
"I don't know what your talking about, my smoothies and grandpa Max's cooking are nothing alike" Ben said shrugging it off
As the four continued to talk and enjoy this time of peace, a large ship came down from the sky and hovered above them. Ben had seen this ship many times before, he knew who it belonged to and he knew what it being here meant.
"Vilgax is back" Ben said
"I thought he destroyed himself after his attempt to use Malware's body as armor" Rook said
"If there is one thing about Vilgax both Ben and I know, its that nothing can stop Vilgax from coming back" Gwendolyn said
"I once threw him out of a planet's atmosphere as Waybig and he still came back eventually" Ben said
"I wonder what his big plan is this time" Kevin asked
"Hopefully it's something we can take care of quickly Ben answered
A red beam came down from the large ship as Vilgax slowly descended down to the ground. He looked different from the last time that Ben had faced him. Vilgax had scars all over his body and a few of the tentacles on his face were either torn or missing. Ben figured it must of happened after Malware was removed from his body.
"Ben Tennyson and company, we meet again" Vilgax said as the red beam from his ship vanished
"Yeah, what is it this time Vilgax?" Ben asked annoyed
"I have come here to kill you and your friends and finally claim the omnitrix as my own" Vilgax answered
"You've been telling me that since I was 10 and so far you haven't even got close to doing so" Ben said with his arms crossed
"Today is a different day Tennyson, unlike my past attempts I finally have a weapon that will change everything" Vilgax replied
Vilgax the held his arm out and a large cannon like weapon formed over his arm
"Where did he get that?" Kevin asked worried
"I thought those were all destroyed" Rook said
"What is that thing and why are you two so worried about it?" Ben asked
"Yeah, I've never seen you two worried about something like that before" Gwendolyn said
"That thing is a tachyon particle accelerator" Rook said
"And what exactly does it do?" Ben asked
"It is designed to accelerate particles then rip them apart molecule by molecule" Kevin answered
"They purpose was to destroy dying stars before they exploded" Rook added
Vilgax laughed at the four of them standing there as they realized what he possessed
"You all are going to die for helping Tennyson stand in my way all those years" Vilgax told them
"How are we going to do this Ben?" Gwendolyn asked
"We're going to play this like it's a life or death situation" Ben answered activating the omnitrix
"I don't mind a good life or death situation" Kevin said as he absorbed the material of his car
"I've always wanted to take a part and put back together a tachyon particle accelerator" Rook said as he activated his prototool turning into its staff mode
"Boys" Gwendolyn said as she transformed into her Lucky Girl form
Ben scrolled through the playlist of the omnitrix and selected the right alien for the job. As the faceplate slid back and the core of the omnitrix popped up, Ben slammed it down and transformed into the alien he selected. Ben became a large white robot like alien with green energy inside of it. The omnitrix badge was located on a belt around the alien's waist.
" Atomix" Ben said fully transformed
"Bringing out the big guns, I like it" Kevin said as he formed his hands into a hammer and mace
"Come and face me heroes, come and die by my hands" Vilgax said
With that the four charged at Vilgax, Kevin went first and managed to lay a few hits on Vilgax. Vilgax however grabbed Kevin by the head and blasted with the particle accelerator point blank. Kevin went flying into his car and the others saw that the metal covering Kevin's body had melted and left a burn mark on his skin.
"Kevin!!!" Gwendolyn said as she ran over to Kevin's side in a panic
"Hey babe" Kevin said
"Are you okay?" Gwendolyn asked as she held Kevin in her arms
"Don't worry about me babe, the matter from my car saved me from the blast" Kevin answered
" Can you fight some more Kevin?" Ben asked
"Yeah I can fight" Kevin answered getting up
" Alright guys, I'll take point while you flank him from the sides" Ben said
"On it" Rook said
"I'll put up some defenses for us" Gwendolyn said
The group now with a better plan readied themselves and went towards Vilgax. Ben threw small atomic blasts at Vilgax while Rook with his prototool now in blaster mode was firing energy blasts distracting Vilgax. Gwendolyn was unleashing magical fire blasts and lighting bolts. Kevin kept his distance but would go in and swing at Vilgax's legs trying to take him down.
"Enough of this foolishness!!!" Vilgax yelled as he unleashed a wave of energy from his body
The energy destroyed Rook's prototool, it transformed Gwendolyn back to her normal. Kevin was no longer covered and in metal and all three of them were on the ground. The only one still standing was Ben in his Atomix form.
" You guys okay?" Ben asked them
"Do not worry about them, they will die as soon as I am finished with you" Vilgax said
" This has gone on long enough Vilgax, it ends here and now" Ben said
"I've been waiting for a real challenge" Vilgax said
Ben charged forwards at Vilgax and punched him with his fist that was glowing from the atomic energy. Ben was surprised when nothing happened to Vilgax. The warlord didn't even flinch from the attack.
" What is going on here?" Ben asked confused
"I am far more stronger then I was when we last fought" Vilgax answered
Ben jumped back as Vilgax fired the particle accelerator at him. Ben used a move called the fizzle whizzle but it dissipated when it hit the beam of the particle accelerator.
"Anything and everything you throw at me Tennyson will be turned into dust" Vilgax said
" We'll see about that Vilgax" Ben said
Ben then floated in the air and began to charge up his atomic energy before raising his arms into the air
" Hamena, hamena, NUCLEAR WINNER" Ben said as he unleashed one of his strongest attacks
The giant ball of green atomic energy was thrown at Vilgax who fired fully powered beam from his tachyon particle accelerator. When the two attacks collided there was a large explosion that shook everything around Ben and Vilgax. The two attacks tried to push one another back but the tachyon particle accelerator beam broke through the atomic energy ball and hit Ben directly on the omnitrix badge. Ben injured from the attack fell out of the sky and hit the ground hard.
Before Vilgax could gloat, Ben's nuclear winner still moved forwards and hits Vilgax point blank. Vilgax tried to block the attack but there was nothing he could do.
"I cannot lose, I won't lose, I've come so far, I will get what is mine" Vilgax said as his body began to burn
" Vilgax, let me save you" Ben said as he reached out towards Vilgax
"Being saved by you is the ultimate disgrace, I would rather die then be saved by you" Vilgax replied aiming the particle accelerator at Ben
" Vilgax don't do this" Ben said still grabbing onto the spot where he was hit
Vilgax charged up the tachyon particle accelerator once more, as he did that the accelerator absorbed the energy from the atomic energy and focused it on Ben. When the weapon fired, it destroyed Vilgax turning his body completely into dust. Ben failed to save Vilgax but as the beam came towards him, he tried to put up a green energy barrier. When the beam hit the energy barrier it ripped it apart and hit Ben. When the beam hit Ben, his body began to slowly tear apart as the atomic energy inside began to leak out. Finally there was a massive explosion, thankfully Gwendolyn was able to put a barrier to protect her along with Kevin, Rook and Zed.
Once the explosion went away all that was left was a massive crater with an injured Ben in it. Buildings were destroyed it seemed like there was nothing left. Safe from the blast, Gwendolyn put her barrier down and immediately ran to Ben.
"BEN!!!" She yelled as she ran over to him
Kevin and Rook followed behind her as they went to check on Ben. Ben's body was badly damaged, there was burn marks all over and deep gashes. When Gwendolyn touched him, she saw that there was blood on her hands.
"He's not looking so good" Kevin said
"Why isn't the omnitrix saving him?" Rook asked
"Look at it, its broken" Gwendolyn answered pointing at the omnitrix
The omnitrix itself was sparking as the faceplate was cracked, pieces of it were missing and the core could be seen
"We need to get him back to the plumbers immediately" Rook said
"I'll grab him" Kevin said picking Ben up
"Be careful with him" Gwendolyn said
Time Skip
Plumber Base
"Azmuth, is my grandson going to be okay?" Max asked Azmuth as they looked at Ben in the recovery pod
"I can't say for sure, I have never seen this kind of damage before" Azmuth answered
"He got hit with a tachyon particle accelerator beam mixed with the atomic energy of his Atomix form" Rook said
"That does not sound good, not good at all" Azmuth said
"Is he going to make it?" Gwendolyn asked
"He is holding on but barely" Azmuth answered
"Why isn't the omnitrix saving him, doesn't it have like thousands of failsafes to prevent this?' Kevin asked
"I designed the omnitrix with all the failsafes it would need to keep the user alive and keep the omnitrix from being destroyed, whatever happened not only injured Ben but also broke my omnitrix beyond repair" Azmuth answered
The group just stood there and looked at Ben who's body was floating in the liquid of the recovery pod
"So there's nothing you can do?" Max asked Azmuth
"I didn't say that, I can do something but it would alter Ben's life more then anything that has ever happened to him before" Azmuth answered
"What is it, what can you do?" Gwendolyn asked
"I can send a signal to the omnitrix which would cause it to fully merge and bond with Ben's DNA and body" Azmuth answered
"What does that mean?" Kevin asked confused
"It means the omnitrix will upgrade itself to the point where it fully be bonded with Ben" Azmuth answered
Kevin was still confused and Azmuth's answer did not exactly help with that
"He means that Ben and the omnitrix will fully become one" Gwendolyn explained to Kevin
"Gwendolyn is right, Ben will no longer just be human, he will be part human part omnitrix" Azmuth said
"That is what you mean when you said his life would change even more" Rook said
"Will it save his life, will it heal all of the damage done to his body?" Max asked Azmuth
"It will do that and much more, this is something that I never wanted to happen, it has never been done before and anything could happen" Azmuth answered
"Then it's a risk worth taking, anything f that will save his life" Max said
"If this is what you wish Max then I will begin the process immediately" Azmuth said
With that Azmuth began to work on merging Ben with the omnitrix, allowing the device and the technology inside of it to bond with Ben. Once Azmuth began, everyone saw that the wounds on Ben's body began to heal as a white and green metallic substance began to grow over Ben's injuries.
"How long will it take before Ben is fully healed?" Max asked Azmuth
"I do not know, it could take days, weeks, months even, this has never been done before, it could maybe even years before he recovers and wakes up" Azmuth answered
"Let us hope that it doesn't get to that point then" Max said putting his hand on the recovery pod
"That is all we can do" Azmuth said before walking away
Ben's Mind
" We will be one, I save you, you save me and together we will save the world"
"Are you sure they will need us when we're ready?"
" I can't say but I know that you will stand out"
"As long as you don't take over and make me sound like a robot or something, I'll be fine"
" We are a partnership both man and machine as one, the DNA I hold and your body will be fully bonded"
"It'll be interesting to see how all of that works"
Unknown Location: 23rd Century
"Sir are you sure we should be in here?" A young man asks an older man in white lab coat
"Who knows what technology these old ruins contain, there could be artifacts before the beginning of the quirk era" the older man answers
The young man let's out a sigh as he continues to walk, suddenly the young man trips over something and falls to the ground
"Be careful Henry, everything in here is over thousands of years old, if you break something it will be the last time we ever see it" the older man told the young man
"Whatever you say professor Woods" the young man says as he gets up from the ground
Suddenly the young man sees something in front of him. It looked like a pod of some sort and the glass was frozen over. As the young man wiped away some of the frost he saw something or someone in the pod.
"Professor Woods, you are going to want and come see this" the young says to the older man
"What is Henry, what have you found?" The older man asks as he walks over to the younger man
As the older man looks at the pod he sees the same thing that the young man saw
"Henry, you may have stumbled upon something greater then anything technology ever" the older man said
Frozen in the body was the body of Ben Tennyson, fully healed from his injuries and now fully bonded and merged with the omnitrix
A/N: Alright readers, if you couldn't tell by the description of the story and what was said by the two explorers, this is going to be a Ben 10/BNHA crossover. Also if you couldn't tell, this story will be the Ben 10 universe and the BNHA universe will be the same. Since its been confirmed that the BNHA time line takes place after the 21st century and in the 23rd century. I will explain how all of this happened in the next chapter and how everything that happened to Ben caused the BNHA timeline to begin. Oh yeah, Ben and the omnitrix are one now, this means that Ben doesn't need to activate the omnitrix to transform and he no longer needs to fully transform his body to use the alien's abilities. So it's kind of like how Skurd was giving Ben parts of the aliens combining them with the alien he already was.
That does not mean that Ben won't fully transform, he can still do that and then some. I will show new abilities with each new chapter and each ability will be different then the last one. I am still thinking if I should put Ben in class 1A with Midoriya and all them or I should make him like a teacher or something. Oh before I forget, I will be using the anime instead of the manga for the chapters and I will be starting after entrance ceremony. Since this is the first chapter, there are no questions for me to answer or comments to respond to I will be keeping this short. Thank you all for reading and for your support, I will be seeing all of you later
