Chapter 1: Welcome to Jump Force

Life as a hero has its dangers and its merits. It takes a wise man to recognize the biggest responsibility bestowed upon them be it through upon arms or by fists. Throughout the Multiverse we have seen these many heroes rise and fall making an impact in the worlds in which they have lived. Any hero can come in many shapes and sizes such as alien martial arts, ninjas, pirates, hunters, adventures, wizards, card players, reapers, swordsman, martial artists, detectives, warriors, monsters, and aliens.

Heroes fight villains, protect the innocent and save the world alone or together with their allies. But right now, heroes from other worlds have joined forces and formed teams to stop a new threat.

But today another hero was lying in an alleyway in a city. This hero was a 16-year-old boy with brown hair, and green eyes. He wears a black t-shirt over a green jacket with two white stripes on the right sleeve, another white stripe on the left side with a big number 10 in a black circle, blue jeans, and black and white tennis shoes. On his left wrist was a white, black, and green wristwatch-like device with a black and green hourglass symbol on the faceplate.

The boy slowly opened his eyes that fateful day; he groaned and stretched his limbs. When opened his eyes and realized he was in an alleyway.

''Where am I?'' he wondered.

This boy was Ben Tennyson or known to the world and the universe as Ben 10, one of the greatest heroes of them all, and on his left wrist was the Omnitrix the powerful device in the universe which allowed the user to transformed into various alien species across the universe. Ben discovered the Omnitrix when he was 10-years old when he, his grandfather Max Tennyson and Gwen Tennyson at a camping site when he walked into the forest as the watch fall from the sky and slammed on his wrist. Since then, Ben had used the Omnitrix to help and save people and fought multiple fights on that fateful summer vacation. Ben has villains over the years such as Vilgax, the Highbreed, The Forever Knights, Hex, Charmaster, Diagon, Aggregor, Malware, and stopped Malturant and ended the Time War.

''What happened?'' he asked himself. Last time Ben remembered was enjoying a nice smoothie with Gwen, Kevin, and Rook when a strange portal opened up in thin air and he was sucked into it.

Ben got up, confused as heck on where he was. ''Doesn't matter where I am, I better call Kevin, Gwen, and Rook have them locate my whereabouts.''

Ben activated his Omnitrix and turned on the telecommunications function.

''Hello? Gwen? Kevin? Rook?''

Static.

''Hello? Gwen? Kevin? Rook?''

Again static.

''Great.'' sighed Ben. ''No signal. ''That's weird.'' Ben played with the communication function to try to get in contact with them and then eventually everyone else.

He walked out of the alleyway and tried to find some sort of contact...when he finally walked out of the alleyway his eyes widened when he discovered that he was...

''I'm in New York City?!'' analyzed Ben.

Indeed, he was in New York City, the city that never sleeps. But someone strange was going on here their roots all over buildings, plus there were empty turned-on cars, and what worse there were no people around in the Big Apple. Ben walked out of the alleyway, and he decided it would be best to asked someone if anyone around the city.

''Who would such as a thing to one of the biggest cities in the world?'' Ben asked himself again.

Before Ben could do anything, he heard an explosion. The Omnitrix Wielder looked at the saw purple energy beams firing, then looked higher in the sky and he saw a black wormhole. And coming from the wormhole where an army of unknown beings consisted male and female the male ones have black skin, wearing battle armors and devices that covers their left eyes, and white hair. Both of their eyes are red.

''What the heck is going on here?''

He then noted another being floating in the sky. This being resembles Japan's demon he has white armor skin with purple bio gems on his forehead, shoulders, chest and elbows.

''My, my...Another city gone completely to ruins.'' laughed the being. ''Good work, all of you.'' he told his army.

The soldiers keep attacking the city with energy attacks as ordered by their leader.

''These fearsome foes from another along with the Venoms who fight beside them...wrought catastrophic damage upon the world.'' spoke an unknown voice. ''But even as the shadow despair spreads across the world, the fight of hope is certain to appear.''

Suddenly something burst across the sky and flew towards the purple villain. Flying him was a man with spiky blonde hair, and green eyes. He wore an orange Gi after it was a dark blue short-sleeved undershirt and seceded by a dark blue tied obi over his waist, blue wristbands a kanji on the back and front-left side of the Gi. He also wore dark blue boots with a yellow border and red laces.

He was flying in a golden ki aura.

''Friezaaa!'' he shouted; he clenched his fist at the alien villain.

The villain now named Frieza caught his fist. The two started crashing with each other with punches.

''What's this? I don't see your little friends.'' said Frieza.

''I don't need anyone's help to stop you!'' scolded the blonde-haired man.

The two of them continued their battle until they are holding back.

''This world is all but done for.'' stated Frieza.

''That's not for you to decide!'' snapped the blonde-haired man.

Ben watches unknown villains attacking New York City led by a demon-like alien. He clenched hands into fists and decided to stop them before if they were people would get hurt.

''It's Hero Time!'' Ben called out his catchphrase.

Ben quickly activated the Omnitrix scrolling through holo-playlist he tapped the icon head he wanted, the faceplate slides opened as the core popped out, he slammed the dial down as his body engulfed in a flash of green light.

When the green light died down standing in Ben's place was a silicon-based alien made of extremely durable crystal. His body is overall indigo, with several dark lines and spots. His hands and face are magenta, and he also sports magenta shards on his back, two on his chest, and one on the top of his head that resembles a horn. His face consisted of a mouth and one large green eye at the center. He wears the Omnitrix symbol on his chest.

''Chromastone!'' he shouted.

''Hey, excuse me!'' called out a voice.

Chromastone turned to see a young man around his age. The young man is slim yet-built of below average height and light-skin color; his facial features and skin-tone. He has blue eyes, and his hair colored is lavender and purple that is soft and straight that parts from the top of his head to frame both sides of his face reaching his ears with two loose stands over his forehead. He wears an indigo-blue jacket reaching abdomen with a logo with the word Capsule Corporation, a black tank-top, dark gray pants with a white belt, golden boots and a computerized watch. And his accessory is a broadsword hanging on his back and over his right shoulder in a red sheath with a blue strap.

Chormastone got into a battle position. ''Who are you? And what do you wanted with me?'' he asked.

''It's okay, I'm a friend.'' reassured the purple haired boy.

The Crystalsapien placed his arms down. ''Okay, then who are you?'' he demanded.

''I'm Trunks.'' introduced the purple haired boy now named Trunks. ''What's your name?'' he questioned.

''You called me Chromastone for now, but my real name is Ben Tennyson and I'm human.'' he responded. ''So, do you know what's going on here? And what's up with the people with white hair, and dark skin?''

Trunks nodded. ''Yes, they are called Venoms, and they are attacking other cities and countries as well.'' he explained.

Chromastone's eye widened. ''Seriously?'' he inquired.

''That's right but I will explain the rest of the details later, but now, you will help us take of them?'' he asked the Crystalsapien.

Ben thought about it for a moment of silence they were beings called Venoms attacking the city; though he'd really need more answers like how did get here and he wouldn't mind helping to take care of the Venoms.''

Chromastone's face turned serious. ''Okay, I'll help.'' He then pointed to the blonde hair man and Frieza. ''But who are they?''

''The one with the spiky blonde hair is my friend Goku, and the guy in purple and white is an old enemy of ours Frieza.'' explained Trunks.

''Frieza! This world put isn't yours to mess with!'' shouted Goku.

Frieza laughed. ''My, such bravado. I wonder how long you'll be able to keep it up.'' he remarked.

However, before Chromastone could say anything suddenly the Venoms came down to them.

''Damn it!'' stunned Trunks. He then turned to Chromastone. ''You ready to fight them.''

The Crystalsapien nodded. ''I'm ready.''

The two heroes got into battle positions as the Venoms charged them. as both Ben and Trunks charged as well. Two Venoms fired large purple energy beams at Chromastone who just stood there doing nothing. However, Chromastone held out his hands and absorbed the energy fired from them. Chromastone's body began to glow the colors of the rainbow. Without warming he unleashed a powerful large ultraviolet beam at the two Venoms sending them flying into a building.

Three Venoms charged at Trunks who pulled out his sword and in seconds he swung his swords across the Venoms' chests and slashed their armors off. The Venoms fall on the ground out cold.

Both Chromastone and Trunks fought the rest of the Venoms together with energy attacks. The duo continued batting until there were two Venoms left remaining. Before Chromastone fired more ultraviolet beams at them one of them hit the Crystalsapien with a fire kick and knocking him to the ground. Then the second one flew into the air and started charging a large black and purple energy sphere.

Chromastone got up on his feet, saw the large and purple energy sphere coming towards him.

''Okay, if normal Chromastone can't get the job done, then it's time to go Ultimate!''

Chromastone slapped the Omnitrix symbol on his chest as four spikes popped out of the device as a flash of green light spread through his body.

When the green light died down. Chromastone is now an ethereal upright standing mass of pinkish-purple crystals with brownish rock areas of his body. His head resembles an uncut prism with two large crystals jutting each shoulder. His chest, wrists, and pelvis are covered in rock. The bottom torso does not have legs, instead a mass of crystals with one large formation jutting out from the center. He wears the evolved Omnitrix symbol on his chest.

''Ultimate Chromastone!'' he shouted.

Ultimate Chromastone then floated in the air. As the energy sphere was coming towards him, Ultimate Chromastone held out his hands. The energy sphere is just Ultimate Chromastone just as thought as Venoms the blast would be enough to kill him, but the blast absorbed into his crystal body. Ultimate Chromastone's crystals and body glowed and the hyper-evolved Crystalsapien fired multiple ultraviolet beams at the Venom knocking him to the ground.

Ultimate Chromasotne then landed back on the ground and then morphed his hands and fired purple crystal shards at the final Venom and finished it off with a crystal boomerang.

''And that's the last of them.'' quipped Ultimate Chromastone as he slapped the Omnitrix symbol; in a flash of green light, he transformed back to normal Chromastone; he slapped the Omnitrx symbol again and transformed back to Ben.

Trunks turned to Ben. ''Good, job.'' he smiled.

Ben returned the smile. ''Thanks.''

Before they could do anything suddenly the defeated transformed into tiny red cubes. Then suddenly a small silver robot with no legs and round oval body and head. It has bright yellow eyes, ears similar to a Majin's and two small arms and a tail, giving the appearance of a robotic legless monkey. It also has the letter J on its stomach.

''Navigator, get the cube!'' ordered Trunks.

''Yes, sir. Commencing retrieval.'' spoke up the robot now named Navigator. The robot's eyes glowed as the cube glows as well as the robot collects the cube.

''Uh, what was that?'' asked Ben in relief.

''That would be an Umbras Cube.'' answered Trunks. ''But I'll explain the rest of the details later.'' Ben nodded in understanding.

''Well, well...'' responded Frieza who was watching everything. ''This is why you can't reply on humans...Let's pick this up another time.''

''Get back here!'' scolded Goku.

''Don't you need to attend to your new friend?'' asked Frieza. ''Good day.'' then flew off, vanishing without a trace.

''Man, he got away.'' commented Ben.

Then Goku came down and powered down as his hair it now spiky black with five spikes in the the front and four in the back, and black eyes.

''You're pretty good!'' Goku told Ben.

''Thanks. I'm Ben Tennyson by the way.'' Ben held out while Goku shook.

''I'm Goku, nice to meet you.'' replied Goku.

''Goku, I think we should head back to base camp for.'' stated Trunks. ''Luffy and Naruto should be finished helping the others.''

''Sure. Besides, I'm getting hungry.'' retorted Goku.

Trunks turned around to Ben. ''You too, Ben. You're welcome to join us at the base camp.''

''Wait, your base camp?'' asked Ben, confused.

Trunks nodded. ''Yes, there someone would explain everything to you.'' he replied.

''Don't worry! We've got lots of great food.'' assured Goku. ''When we get back to base you would like to have lunch with us?'' he offered.

Ben thought about it for a moment, and he didn't even have lunch yet. ''Sure, that would be great.'' he answered.

''Okay, then let's go.'' spoke up Trunks.

''Activating the teleportation portal.'' announced Navigator.

In a flash of blue and white light the four of them teleported away in thin air and vanished.


Somewhere else...

Something in an unknown location... When the blue light died down the group arrived.

''Here we are.'' announced Navigator.

Goku stretched out his arms. ''Hmm...It still feels weird having a machine transmit me around like that.'' he uttered then walked off.

Ben looked at Trunks who shrugged his shoulders. Then they walked up and caught up with Goku. As they were walking, Ben looked at the base camp it was a huge stadium, they had gift shops, cafes and a lot of other things. They there were also monitors.

''Wow, man this is place is amazing.'' commented Ben.

''I'm glad you're starting to like it here.'' remarked Trunks.

The trio saw two individuals up ahead. One of them is a young man with black shaggy hair, round eyes and a slim muscular body. On his head a trademark of a straw hat. He wears shorts, blue trousers with cuffs, sandals and a sleeveless red vest. He also has a scar with two stitches underneath his left eye and a large X-shaped scar on his chest.

The other one was another young man with spiky yellow-blonde hair, blue eyes, along with whiskers upon his cheeks. He wears a black and orange jacket with a red swirl crest on his back, orange pants with a holster at the right knee, black sandals, and a bandanna wrapped around his forehead with a symbol up the metal over it. He also sported bandages all over his right hand, the rest of which couldn't be seen due to his long sleeve.

''Hey, Goku's back.'' spoke the yellow-blonde hair boy. Ben, Goku, and Trunks come up to them.

''Sorry, guys. Frieza got away.'' apologized Goku.

''Don't worry about it. Just get him next time!'' assured the boy with the straw hat.

''Yeah, you're right.'' agreed Goku. ''So, do we have anything to eat? I'm starving?'' he asked.

''Hee hee hee! I already at it all!'' giggled the straw hat boy.

''Wha-? No way!'' exclaimed Goku, shocked.

The yellow blonde turned to Ben. ''By the look who's the new guy?'' he questioned.

''I'm Ben Tennyson.'' Ben introduced himself. He took out his hand and which the yellow haired boy shook it.

''Nice to meet you, Ben. I'm Luffy. Monkey D. Luffy.'' introduced the boy with the straw hat now named Luffy.

''And I'm Naruto Uzumaki.'' introduced the blonde-haired boy now named Naruto.

''Everyone from this world freaks out a bit when they first come here.'' informed Trunks.

''Okay.'' said Ben then until something hit him. ''What do you mean this world?''

''After all, they're seeing a world straight out of a comic appear before their very eyes.'' spoke a new voice.

Ben and everyone else turned to see an African American man with a bald head wearing black glasses, a black jacket with various blue belts and a cape, blue gloves, yellow pants, and blue boots.

''Director!'' replied Trunks.

''Director?'' asked Ben in relief.

''Welcome to Umbras Base.'' greeted the Director. ''This is where those who battle with Venoms come together to ensure humanity's survival. My name is Glover.'' introduced the Director now named Glover.

Glover took the group to a lookout where they can talk.

Glover began. ''Most of us are from the same world, as such as myself included.'' he explained.

''Wait I'm in another world?!'' proclaimed Ben, surprised. ''Of course, that would explain why I can't contact my friends.'' he realized.

''Allow me to explain. There are whole worlds out there, beyond the world of reality where we reside.'' continued Glover. ''Those worlds are known collectively. as 'Shonen' Thanks to both our various enemies that have appeared from Jump Worlds...and the ones we call 'Venoms' who fight beside them, our world has been plunged into chaos and destruction. Fortunately, we have heroes who are ready and willing to stand against the threat this enemy poses. Together, they are known as the 'Jump Force.' Jump Force consists of heroes from the Jump Worlds, like Goku and Trunks...And of heroes like you, who hail from another world called 'Cartoon Worlds. But also, other worlds such as 'Shonen.'

''Wait, Cartoon Worlds?!'' asked Ben, simultaneously. ''That does means...''

"'Yes...But with your powers you can fight alongside them. Those cubes Trunks told you before. We call them 'Umbras Cubes.' The one that came from the Venoms you defeated is identical that Navigator collected. Before you asked yes, the Venoms were once human. They are the result of those with malicious intent gaining power from the Umbras Cubes. The Venoms have been gathering evil-minded people, providing them with cubes...And growing their numbers as they expand their territory in the world of reality.'' explained Glover. ''If we do not act, the entire real world will fall into their hands. To Stop the Venoms, it is not enough to merely defeat them. We must also collect the cubes used to create new ones. Will you join us, Ben Tennyson?'' he asked the teen hero.

Ben thinks for a moment he has no way to go to his world, he wished Professor Paradox would come and take him back, but he couldn't ignore a world in danger and as well its people what kind hero would he be if another world in danger. After another moment of silence, he makes up his decision.

Ben smirked. ''Okay, I'm in.''

''Good, now you are a member of Jump Force. I can't wait to see to see what you are accomplish.'' smiled Glover.

Ben nodded.


New York City...

Back at New York City two beings were on top of a building. One of these beings is a tall, muscular bald humanoid and purple eyes, and has red markings on his scalp and around his eyes. He wears a black suit with gold armor pieces over his body, with his most notable feature being the insect-like shell pieces hanging from the back of his chest armor. He also wears olive green military-esque gloves and boots.

And the being is a green skin, beautiful busty humanoid fairy-like creature with white spiky flowing hair, yellow eyes and translucent insectoid wings. She wears a red leotard red glove that stretch to her forearms and red thigh-high boots.

''How is the plan proceeding, Gelena?'' the armor being asked the fairy-like lady.

''The so-called 'Ultimate Jump Force' is desperately trying to hold back the tide, but they won't be a problem.'' answered Gelena. ''Our numbers are growing steadily.

''I see...That's good to hear, but don't get complacent. We can't afford to waste any time.'' said the armor-being. His name was Kane.

''Haha, so hasty.'' chuckled Gelena.

''Of course. There's not a moment to lose, after all. This contemptible world must be changed. And I will be the one to change it.'' stated Kane. He held out his hand as the clouds turned dark and purple lightning flashes.


Umbras Base...

Back at Umbras Base Ben was with Director Glove and Navigator. Looking at three commander wings with 'A, 'B' and G'.

''Navigator here will fill you in on the details. Go ahead, Navigator.'' Glover told the robot.

''Yes, sir. From a tactical perspective, the Ultimate Jump Force is broadly divided into three teams.'' informed Navigator.

''Uh, three teams?'' asked Ben.

''That's correct. Team Alpha, who works to contain the Venoms' invasion.'' Goku leads Team Alpha.

''Team Beta, who is tasked with reclaiming territory that the Venoms have occupied.'' continued the robot as Luffy leads Team Beta.

''And Team Gamma, who focused on infiltrating enemy territory in order to gather intel.'' finished as Naruto led Team Gamma.

''You too will join one of these teams.'' Director Glove told Ben. ''There's no need to overthink it. You too will join one of these teams. But however, we are setting up a fourth team.''

''Fourth team?'' inquired Ben.

''Yes, we'll need to contain the invasions, gather intel, and reclaim territory. For now, you should visit each team and learn more about Jump Force before making your decision.''

Ben nodded. ''Okay, after we recruit new members, I'd like to become the leader of the fourth team.''

''Hmm, you have leadership skills?'' demanded the Director.

''Yes, I do back in my world I the leader of my own team and I've been for a year now.'' answered the Omnitrix Wielder.

''Okay, then very well, Ben may become leader of the fourth team then you should pick a team for now. Goku, Naruto, and Luffy's teams should be here soon be sure to choose a team.'' replied Director Glover.

''Thank you, Director Glover.'' he responded.

''You're welcome.'' smiled Director Glover. Then he takes his leave.

As the Director leaves Ben was left alone until a voice caught his attention. ''Yo, Ben.'' Ben turned to see Goku coming from his base along with other individuals.

One of them is a young man with fair skin, green eyes, and short spiky red auburn hair. He lacks distinctive pupils or eyebrows. He wore long-sleeved crimson coat and full-length dark trousers with a pair. Over the coat he wore two buckled belts, a grey vest held in place by a single strap over his left shoulder, and two buckled belts which also he used to carry a sand guard on his back.

Another one was another young man with muscular build, lightly tanned skin. green hair and black eyes. He has a scar over his left eye, and he has three golden earrings on his left earlobe. He wears a long open dark-green coat closed on his wrist and held by a red sash in which his three swords are tucked in, and a black bandana tied around his left forearm. His coat exposes his bare chest, revealing his green haramaki underneath his coat.

And the last one was a very tall and muscular green man with elf-like ears, five fingers with white nails. He has several patches on his arms which are pink. He wears a dark purplish-blue Gi, pointedly orange shoes and sky obi. He is also wearing a white turban with a dark blue and a white cape along with it.

''Oh, hey Goku.'' greeted Ben. Looking at the three guys with him. ''So, these guys you're teammates?'' Goku nodded.

''So, you're the new recruit? Looks like you've got what it takes.'' smirked the green haired guy. ''Why don't we have a little sparring session and find out.''

''Zoro! Go easy on the new recruit.'' the green man told the green haired guy now named Zoro.

''Be quiet. You're bothering me...'' muttered the red-haired guy.

''If it's not something it's another...

''So, who are you guys?'' Ben asked the members of Team Alpha.

''My name is Gaara.'' introduced the red-haired boy now named Gaara.

''The name Zoro. Roronoa Zoro.'' introduced Zoro.

''And I'm Piccolo.'' introduced the green man now named Piccolo.

''Hey, Ben.'' Ben and Team Alpha turned around to see Luffy with 3 others.

One of them was a young slim, yet muscular long-legged with blonde hair. His' hair is brushed over the right side of his face and his eyebrow; both have spirals at different ends with opposite directions and his hair is covered in his right eye. He wears a black, double-breasted suit with golden buttons and a tie together with a yellow dress shirt.

While another was a young boy with a fair-skinned lean, well-built frame and short height. He has spiky blond hair, blue eyes and two whispers. He wears a black jacket with dark pink stripes. Beneath his jacket-which he leaves unzipped-he wears a white T-shirt and a bolt tied to string around his neck. He wears black pants with bandages on the right side and black sandals.

And the final member of the team is a very tall and slender beautiful woman with long black hair that extends past her waist with locks of hair that frame her face down to her chin and shows off her high forehead, black eyes with long voluminous eyeslashes and pale skin. She has a narrow waist and very large breasts, and with serpent earrings. She wore a purple dress with Kuja designs on it and purple hell pumps and black high-heeled shoes.

''Ben, meet my team. Team Beta.'' Luffy introduced his team.

''Nice to meet you, so who are you?'' he inquired.

''I'm Sanji.'' introduced the blonde-haired guy.

''I am Hancock. Boa Hancock.'' introduced the beautiful black-haired woman now named Hancock.

''And I'm Boruto Uzumaki.'' introduced the little blonde-haired boy now named Boruto.

Ben's eyes widened. ''Are...You related to Naruto?'' he asked.

''Yep, I'm his son from the future in our world.'' answered Boruto.

''Hey, Ben you wanna be a pirate? If you do you should join our team.'' offered Luffy. ''We've got Sanji too, so we've got the beat grub around!''

''The only one I need on my team is you, Luffy.'' cheered Hancock.

''If you're okay with a team like this, you're free to join us. Or not. It's you to you.''

''Okay.'' nodded Ben.

''Hey, Ben!'' Ben and both teams turned to see Naruto, and Trunks along with three others with them.

One member was a tall and muscular young man with long blond hair, he had a scar he acquired over his left eye, he styled to cover up his eye scar. He wears a long jacket with a buckle on the left sleeve, with a blue shirt and vest, a frilled cravat, and a simple belt holding a pair of loosen light-blue pants with black boots to be wrapped with buckles with cloth bracings. He also wears a pair of brown gloves and a black top hat with goggles over the band.

The next member was a man with spiky silver hair, and black eyes. His face is covered in a mask, black forehead protector that covers his left eye. He wears a flak jacket, dark pants, and a long sleeve shirt. He also wears fingerless gloves with a necklace underneath.

And the final member was a teenage robot with spiky black hair and black eyes. He wears a grey zippered, high-collared short-sleeved shirt, blue wrist warmers. He also wears dark blue pants and a purple rope belt.

''This is my team. Team Gamma.'' said Naruto. ''Just call me 'Captain Naruto?'

''I see you're in a good mood. Naruto.'' commented Trunks.

''Yeah. I'm glad to see him motivated.'' added the blonde hair guy with the top hat.

''Just as long as he does something useful with that motivation.'' remarked Trunks.

''Haha, that was brutal, Trunks.''

''...I can hear you; you know.'' argued Naruto.

''Enough poking fun at Naruto. He is our leader, after all.'' spoke up the silver haired man. He then turned to Ben. ''Oh, where are my manners. I'm Kakashi Hatake. 'Introduced the silver haired man now named Kakashi.

''My name is Sabo.'' introduced the top hat guy now named Sabo.

''Nice meet to you too.'' smiled Ben.

Kakashi turned around to the black-haired boy. ''Sasuke! You come greet the new recruit, too!'' he told him.

The black-haired boy now named Sasuke turned around to see Ben. ''I'm Sasuke Uchiha.'' he introduced himself.

''I see you never change, Sasuke. You kind of remind me of someone...'' pointed out Trunks.

''Nice to meet you...Sasuke.'' greeted Ben, curiously. Then he noted like Sasuke...sounds just like him. ''Hey, in case you haven't noticed me, and you sounded just alike each other...'' he noted.

Everyone's eyes widened in shock too. Realized Ben was right he and Sasuke's voices sound similar to each other. Then Trunks broke the silence.

''So, tell me, Ben, what do you think of Team Gamma?'' he asked. ''We may look a bit haphazard, but we're really good at infiltrating enemy territory and gathering intel. If you like what you see, I hope you'll consider joining us!''

''So, Ben which team will choose to join?'' wondered Luffy.

Ben looked at the three teams in deep thought. Before he could make his decision but suddenly something captured his attention. Ben looked at his left wrist and saw his Omnitrix glowing yellow. Suddenly, the faceplate slid back and allowed the core to pop. A yellow beam of light fried from the device and scanned Goku, and Piccolo. After it finished scanning them, the light disappeared as the Omnitrix shifted back to its normal position.

''Unknown DNA Sample Acquired. Scanned Complete.'' spoke the Omnitrix.

Everyone looked at Ben, dumbfounded at what his watch just did.

''Wait Goku and Piccolo are aliens?'''' thought Ben. Then Ben made up for his decision. ''Okay, I'll chose Team Alpha, Team Beta and Team Gamma.''

''What?! All of our teams?!'' cried Trunks.

''Yeah.'' replied the alien hero. ''Only as a member for one at a time.''

''But, why?!'' demanded Goku.

''Because Director Glover said he was setting a fourth team, and I could be the leader until I wanted to work with you guys' teams for a while until I'll find other heroes to join me.'' explained Ben. ''So, what you do guy think?''

Goku, Luffy, and Naruto looked at each other for moments in deep thought before looking at Ben. ''Okay then, welcome aboard.'' smiled Goku.

Luffy and Naruto nodded in agreement.

''If we're gonna work together we should get to know each other.'' inputted Ben. ''Like what you guys can do and what your worlds are like. And how did we all end here.''

''That's sounds such a good idea to me.'' agreed Naruto.

''Yeah, that's true most of us are from the same world.'' nodded Luffy.

Goku spoke up first. ''Well, me, Piccolo and Trunks are from the same world. In our world we're martial artists.'' he began. ''We used 'Ki', a life force energy we can used to create and manipulate many different techniques and powered up, and to gain enhanced strength, speed, and endurance.'' he finished.

''That's good.'' compliment Ben.

''My turn to explain.'' responded Naruto. ''Me, Sasuke, Gaara, Kakashi-Sensei and Boruto are a world of Ninjas. As for our powers we used 'Charka' Charkas are gates in our bodies we used to create Jutsu Techniques. There are three types of Justsu:Taijustu for martial arts. Ninjutsu, harming weapons and tools. elemental styles: Wind, Water, Earth, Fire and Lightning. Genjustu to create illusions.''

''That's awesome.'' grinned Ben.

''And finally. Me, Zoro, Sabo, and Hancock are from a world of Pirates.'' stated Luffy. ''Me, Sanji, and Zoro are a crew called 'The Straw Hat Pirates and I'm the Captain.''

''Okay, are there people part of your Crew?'' questioned Ben.

''Yeah, there Nami, Usopp, Chopper, Robin, Franky, and Brook.'' answered Luffy. Both Sanji and Zoro nodded.

''I'm the Swordsman of the Crew.'' smirked Zoro.

''I'm used a martial arts style called 'Black Leg Style' which with a complete emphasis on kicks.'' replied Sanji.

''As for my powers I ate a special fruit called 'Devil Fruit.'' retorted Luffy. ''Devil Fruits would grant anyone special powers whoever ate them.''

''That's correct there are three different classes. The first and most common class of Devil Fruit is the Paramecia which granted the user superhuman abilities.'' added Hancock. ''The second class is known as Zoan, allow ab eater shapehifting powers that deal with animals.''

''And finally the third class is the Logia.'' said Sabo. ''These fruits allow the eater to control elements like fire, ice, lightning, and others. But due to their powers, most physical attacks do not hurt them.'' he finished.

''I ate the Gum Gum Fruit which my body rubber.'' smirked Luffy stretching his arm larger.

''I ate the Flame Flame Fruit which gets me fire powers.'' Sabo engulfed his hands on fire.

''And I ate the Love Love Fruit I can lust or love and turned them into stone.'' finished Hancock.

Ben couldn't help but smile. All of his new friends have amazing powers and cool worlds

''Alright, you're turned.'' spoke up Trunks. ''What are your powers?''

Ben realized it was his turn. ''Alright. Well I get my powers from this.'' He pulled his jacket left sleeve and showed them at Omnitrix.

Everyone looked at the watch on his left wrist in wonder and confused.

''That's just a wristwatch.'' pointed out Sasuke.

''Yeah.'' agreed Zoro.

''Wait a minute I've been noticing it before.'' noted Trunks.

''Me too.'' agreed Goku.

''It's not just a watch it is called the Omnitrix.'' explained Ben. ''It allows me to transform different aliens with different powers and abilities in my universe.''

''Wait that device transformed into aliens?!'' proclaimed Kakashi.

''Yeah.'' answered Ben.

''So that's how you transformed into that purple crystal guy.'' recalled Goku. The alien hero nodded.

''So, how did you get your watch?'' asked Luffy.

''Yeah, I'd like to know too.'' agreed Naruto.

''Oh, it started when I was 10 years old. My grandfather Max Tennyson took me and my cousin Gwen out for the summer. When we were camping, I walked into the forest, when I saw a meteor crash into front of me. I decided to go look, and found a strange pod and then the pod opened and the Omnitrix stuck itself upon my wrist. After saving saving people from a robot drone I've decided to used the Omnitrix to become a hero, me, Gwen, and my Grandpa went from place to place helping people and stopping villains from take over or destroyed the world since then.'' explained Ben.

''Really?!'' asked Trunks amazed. ''You did all that when you were 10?''

''Yeah, and I've been doing it for 6 years now.'' he answered.

''That is amazing!'' exclaimed Goku, Naruto, Luffy, Sabo, Hancock, Zoro, Boruto, Sanji and Trunks.

Gaara, Kakashi, and Sasuke didn't make any comments. Piccolo just grinned. Though they have to admit Ben is really good heroic.

''So, can we see an alien?'' requested Luffy, excited. ''Please?!''

''Yeah!'' agreed Goku and Naruto.

''Sure.'' smiled Ben.

Ben activated the Omnitrix tapping the faceplate scrolling through the playlist he tapped the icon head he wanted and slammed the dial; as his body engulfed in a flash of green light; everyone else shielded their eyes from the light.

When the green light died down standing in Ben's place was a humanoid moth-like alien, whose four wings and two antennae-like wings folds can hold up into a poncho-esque robe with a hood, giving him the appearance of a phantom. He has a black body with blue patching on his slender chest, and running along his legs and arms, the latter reaching up to the back of his neck. He has cyan patches that resemble ice chunks on his legs and arms, which also contain three cyan patches of their own. His face is blue that has harsh black lines surrounding his eyes and mouth, which all meet at the center of his face. He also has a black marking on his head that extends over his scalp, forcing the remaining blue parts of his forehead into a Y-shape. His eyes are bright green, with small darker spots inside. His mouth is a frown showing four bluish-white teeth, which rarely moves, even when speaking. He has three pointed fingers and a thumb on each hand, and three toes on each foot; two in front and one behind. He unfolds his wings. He wears the Omnitrix symbol on his chest.

''Big Chill!'' he shouted an eerie whisper voice.

Everyone's eyes as they looked at the Necofriggian in awe.

''Whoa...''' breathed Goku, Kakashi and Zoro.

''Amazing...'' commented Hancock.

''Cool...'' smirked Naruto.

''G-Ghost!'' cried Luffy.

''Luffy, calm down.'' Gaara told him.

''Yeah, it's just Ben!'' yelled Sanji.

''So, what this guy can do?'' inquired Sasuke.

''He can do this.'' stated Big Chill. Big Chill turned intangible and phased through the ground. Then appeared behind them.

''Uh, what was that?!'' gasped Goku in shocked.

''Intangibility.'' replied the Necorfriggian.

''It's just like Space-Time Ninjutsu.'' thought Naruto, Sasuke, Gaara, Boruto, and Kakashi with shock expressions.

''What else this form can do?'' questioned Trunks, curiously.

''He can do this.'' Big Chill took a deep, and fired an icy mist right at a nearby table. Ice began to form and encase the table in ice.

Everyone looked at the now frozen table.

''Whoa, he has ice powers too?!'' shouted Sabo.

''I'm starting to like this guy.'' grinned Zoro.

''Me too.'' agreed Piccolo.

Big Chill tapped the Omnitrix symbol on his chest, in a flash of green light he transformed back to Ben.

''Alright, now that we explained our worlds. So how did all get here?'' he asked them.

The three teams looked at each other for a moment and decided to tell.

Goku was the first one to speak. ''Well, me, my friends and family were having a party on my friend Bulma's private islands when suddenly a dark storm came out of nowhere then Trunks came from the future before he could explained the storm, we were sucked in the storm all with half of world. Then the next we know we were in another city that we've never seen before.''

''Me, Kakashi-Sensei, Gaara, Boruto, and our friends were on a mission together. After the mission a storm came out of nowhere and sucked us and our world here.'' Input Naruto.

''And me, Sanji, Zoro, Hancock, Sabo, and the rest of my crew were sailing on our ship the Thousand Sunny through the Grand Line to the find the One Piece so my felt my dream to become King of the Pirates when a dark storm appeared out nowhere then we sucked in. Though Hancock and Sabo aren't part of our crew they were sucked in as well. Next we knew we were here.'' finished Luffy.

''People were surprised to see us.'' implied Trunks. ''And then our enemies started appearing in this world too. Soon our worlds have messed with this one.''

''So, what about you how'd you get?'' asked Piccolo.

''Well, I was at a place called 'Mr. Smoothies' with my friends after we stopped some bad guys from robbing a bank then some black portal appeared and I was sucked in. Next time I knew I was in New York City when I ran into Trunks and Goku.'' answered Ben.

''That was heavy.'' commented Gaara.

''Tell me about it. So where are your friends?'' Ben asked them.

''We don't know. We were separated. We don't know where they are right now.'' replied Naruto with worried look.

''It's gonna be okay, the sooner we will stop the Venoms and then everything will go back to normal.'' reassured Ben with a smile.

Everyone else smiled too including Sasuke and Gaara thought they usually smiled but they couldn't it.

Before they could say anything else. The navigator caught their attention. ''Everyone. The Director calls you for a mission.''

''A mission?'' wondered Goku.

''Yes, so Goku, Piccolo, Naruto, Trunks, and Ben. Come to the control room.'' spoke Director Glover's from the speakers.

Goku, Piccolo, Naruto, Trunks, and Ben looked at each other and nodded heading towards the control room.


Somewhere else...

Somewhere on an unknown planet filled with three suns. It is also home to the host of ambient life such as fish, frogs, slugs, and dinosaurs. This planet is called Planet Namek home to Piccolo's species the Namekians.

However on Planet Namek three Venoms were a man.

This man is well-built of below-average stature, standing 164 centimeters tall. His hair is black and spikes upward. He wears a blue-skin tight jumpsuit with battle armor with yellow straps, white boots with yellow tips, and white gloves. This is Vegeta the Prince of All Saiyans.

Vegeta was smirking and with his arms across the chest. Before he could do anything; suddenly a red and black cube appeared behind on the ground and inficted into his body. Vegeta's eyes glowed red and a dark black aura engulfed him.

''Ahhhhh...''' he screamed. And then the now mind controlled Prince walked towards the Venoms. And they all walked together.


Umbras Base...

Ben along with Goku, Piccolo, Naruto, and Trunks walked down a plane of stairs from the last room of the base. The group keeps walking until may to the control room with monitors and a map of the world. They meet up with Director Glover stand at his high-tech table.

''Good you guys are here.'' said Director Glover.

''What happened?'' demanded Trunks.

''We have received an SOS from Planet Namek. It is under attack by the Venoms.'' explained the Navigator.

''What?!'' yelled in delief.

''Man, these guys are relentless.'' declared Goku.

''Why are they attacking there?'' asked Ben.

''We have also confirmed that Vegeta has been spotted there.'' continued Navigator.

''Dad?!'' groaned Trunks.

''Dad? Vegeta's your old man?'' questioned Naruto.

''Yes, he is...'' replied Trunks.

''If Vegeta has joined the Venoms' side, we must mobilize the entire Jump Force.'' elaborated Director Glover.

''Wait!'' called out Goku. ''Vegeta may've been a bad guy, but he's not anymore. There's no way he'd join the Venoms.''

''Goku is right.'' agreed Trunks. He turned to his leader, Naruto. ''Naruto would it be okay if I accompanied Team Alpha on this mission?!''

''Go for it!'' ordered the young ninja.

''Thank you, sir!'' stated the son of Vegeta.

''Very well then. Now that that's settled, you'll leave as soon as possible. Ben i want you to accompany them too, this is your first mission with Team Alpha.'' commanded Director Glover.

Ben nodded. ''Yes, Director.''

''All right! Let's get going!'' ordered Goku.


Planet Namek...

In a blue and white light. Goku, Ben, Piccolo, Trunks have teleported to Planet Namek.

''Teleportation complete.''

''Father...'' muttered Trunks.

Ben turned to Trunks. ''It's gonna be okay, Trunks we'll find your father.'' he assured.

''Piccolo, you hands the Venoms!'' ordered Goku.

''Right.'' replied Piccolo.

Goku turned to Ben and Trunks. ''Trunks, and Ben, you come with me. The three of us are going to find Vegeta'' he told them.

''Yes, sir!'' they responded.


Ben along with Goku and Trunks ran off to find Vegeta. After searching for a while they finally him along with some Venoms.

''Go.'' Vegeta ordered the Venoms.

Venoms charged at the heroes.

''Out of our way!'' scowled Goku.

The trio charged at the Venoms as the battle begins.

Music (Dragon Ball Z Opening Theme:Chala Head Chala)

''It's Hero Time!'' cried Ben.

Ben activated the Omnitrix scrolling through the playlist he tapped the icon head he wanted and slammed the dial; as his body engulfed in a flash of green light.

When the green light died down standing in his place was a plasma-based life-form whose body is composed of a super yellow hot inner plasma body covered by dark red volcanic rocks. As a fire-based entity, his body radiates high amounts of heat. His feet have a slight oval-like design with only two toes and one back toe. His collarbone resembles a volcano which generates fiery 'hair' that covers his head, leaving a mask-like face visible with no or ears. He wears the Omnitrix symbol.

''Heatblast!'' he shouted in a deep and raspy voice.

Heatblast used his pyronkiesis to shoot fire balls at a Vemom who dodged them in ease. Heatblast charged up and fired a powerful blast of fire at Venom sending it away.

Goku bend out his hands. ''Ka-me-ha-me-ha!'' he chanted as a fire fired a white-blue energy attack from the palms of his hands and fire it at Venom knocking away in the sky.

With the Venoms defeated. The trio faced Vegeta.

''Vegeta! What's happening to you?!'' snarled Goku.

''Father, please! Snap out of it!'' glowed Trunks.

Vegeta didn't responded.

''Oh no! It's like he can't even hear us.'' realized Trunks.

''Rr...rrraaah!'' groaned Vegeta in pain.

''Looks like talking isn't gonna get us anywhere...Trunks! Ben! Get ready!'' exclaimed Goku.

''Y-Yes, sir!'' spoke Trunks and Ben who turned back to human.

Vegeta charged at them. Ben quickly activated the Omnitrix again and slammed the dial.

When the green light died down standing in his place an alien resembles a semi-armored Velociraptor. He has black orbs on his feet, a black tail with five blue stripes, and bulky claws on his three fingers that can only open and close. He wears a black cone-like helmet with a protective visor that slides over his face. When the visor is lifted, one can see his blue face, green eyes, black lips, and stripes running under and in between his eyes; the rest of his head's features are unknown. He wears a black bodysuit and turtleneck-like shirt with a white stripe on the center. He wears the Omnitrix symbol on his chest.

''XLR8!'' he shouted in a raspy voice.

XLR8's visor went up and rushed over to the Prince of all Saiyans in a blue and black blur. Vegeta tries to punch XLR8 but he easily dodged thanks to his reflexes. XLR8 punched him in the chest and kicked him across the ground.

An angry Vegeta got back on his feet. He curls his fingers and places both on his hands together at chest level facing the same direction so that the palm of one hand is on the back of the other. ''Galick Gun!'' he fired a powerful blast of purple energy firing it at the Kineceleran.

Then Goku stood up and held out his hands. ''Kamehameha!'' he fired another Kamehameha to blocked Vegeta's Galick Gun. The Saiyans' attacks keeping firing until Goku boosted his Kamehameha and overpowered Vegeta's Galick Gun as his Kamehameha hit Vegeta knocking him back some.

''My turned.'' quipped XLR8. As he rushed over and circled around Vegeta trapping in a tornado. ''Trunks now!'' he called out to the purple haired boy.

''Right.'' he responded. He performs a series of rapid arm movements, ending his arms crossed the chest, before placing his palms forward with the thumbs and index fingers toughing each other, forming a diamond shape. ''Burning Attack!'' he yelled as he fired an energy sphere from hi palms towards his father, Vegeta knocking on the ground, defeated.


With, Vegeta defeated on the ground. The trio stand in front of him.

''Hnng...'' groaned Vegeta.

''Whew. We did it.'' remarked Goku.

''Huh? Look!'' proclaimed Trunks.

Vegeta slowly gets back on his feet.

''Father!'' shouted Trunks in disbelief.

Suddenly the Umbras Cube that controlling him engulfed from his body.

''A Umbras Cube...I've never seen one with an ominous aura.'' pointed out Trunks.

''Judging by it I would have to guess it was controlling him.'' suggested Ben who turned back to human.

''Navigator retrieve the cube.'' ordered Trunks.

''Understood. Commencing retrieval.'' replied Navigator's eyes glowed as the Umbras Cube glowed in a white light and the robot collected the cube.

Vegeta's black aura disappeared as he went back to his normal self. ''Nnh...Where am I?'' wondered Vegeta. He looked up to his future son and rival. ''Kakarot? Trunks? What's going on?'' he inquired

''Father, you're back to normal! Thanks goodness...'' smiled Trunks.

Ben nodded in agreement.

''Can you hear me, Director?'' asked Trunks.

''Is it over?''' asked Director Glover from Navigator's voice speaker.

''I was so worried that Father had gone back to his villainous ways, so this an enormous relief.'' stated the Half Saiyan.

''Hey! What's going on here? Tell me in plain English!'' demanded Vegeta.

''Allow me. You were under the control of an Umbras Cube. We believed that the Cubes' power could only be used for evil ends if their host willed it so.'' explained Director Glover. ''But it seems that the Cubes can also be used in other ways...In your case, the Cubes inside you had already been infected by someone else's powerful malicious will...In turn giving them the power to control you against your wishes. We had best assume that there is some larger figure controlling the Venoms from the scenes.'' he continued.

''Damn it...! Who did this to me?!'' snapped Vegeta.

''We're still looking into that at this point.'' answered the Director of Jump Force.

''Hmph...Hey! All of you!'' stunned Vegeta. ''I want in on this Jump Force business! I'm gonna find who did this and make them pay!''


Umbras Base...

Ben, Team Alpha, Trunks and Vegeta all returned to the base. They were now in the Control Room with Director Glover.

''Well done, team. Planet Namek is now safe thanks to your efforts. Rescuing Vegeta was also a great turn of events.'' said Director Glover. ''Now that we know that Umbras Cubes can be used to control others...We also know now that there is still much learn about their power.''

''Hmph...I suppose I own my thanks.'' Vegeta told the team.

''However, our true battle is only just beginning. In order to restore peace to our world, and to the other worlds...'' continued Director Glover. ''We cannot only focus on defeating the Venoms and collecting Umbras Cubes. From now on, we must also take pains to rescue our teammates that have fallen under malicious cube control.'' he finished.


Unknown place...

In what appears to be a throne room a shadowy figure was what looks a book with a black and red aura.

The pages of the book of the world are messing with the Jump Worlds.


Umbras Base...

In the Control Room, Ben, Goku, Hancock, Naruto, and Luffy were talking to each other. While Vegeta and Piccolo were standing across the wall with their arms cross their chests.

Until Director Glover and Trunks came into the room.

''Ben has really become part of the team.'' said Trunks.

''The Jump Force knows a powerful ally when they see one.'' replied Director Glover. ''Everyone, your attention please.'' he announced. ''Our next mission is to rescue one of our teammates who is being controlled by an Umbras Cube. To date, we have focused our efforts on central North America.''

The monitors showed red dots all over America.

''However, if we were to recruit more powerful allies we would be able to expand the scope of our operations. I trust you will do your best to help accomplish this goal..'' he continued. He walked to Ben. ''That goes for you too Benjamin.''

''Yes, sir.'' nodded Ben.

Director Glover smiled. ''Good, because I have a mission for you.''


A/N:Well that is for Chapter 1 readers I hoped you guys like it and enjoyed it.

I have written Ben 10 and other anime crossovers this time it is an anime x-overs. And I go with the anime crossover fighting game Jump Force.

I've read stories where joined or travel worlds crossover with Shoenn Jump series.

Such as Bleach:Ultimate Alien Volumes 1 and 2, and Remake (Ben 10:Ultimate Alien and Bleach) by Bigby the Bad Wolf.

Omniverse Ninja (Ben 10 and Naruto) by Isom.

Ten Piece (Ben 10 and One Piece) by Spartan of Chaos.

Omniverse Clover (Ben 10 and Black Clover) by Shinbo260.

Tutors of the Academia (Ben 10 and My Hero Academia) by Shinbo260. And other Ben 10 and My Hero Academia crossovers.

Ben 10ZSuper (Ben 10 and Dragon Ball Z) by Anime0C0Manga.

JoJo's Alien Adventure (Ben 10: Ultimate Alien and JoJo's Bizarre Adventure: Stardust Crusaders) by Bigby the Bad Wolf.

And they're really good stories. This time around Ben is teaming up with the most popular anime characters all of time.

Also, Ben have a Saiyan and Namekian. I know Ben can power ups with the Saiyans with his most powerful forms.

Like I said before this story is gonna be different from the game, I added other characters and Shonen franchises that haven't appeared in the game.

Also, Ben have is having a team of his own I haven't decided who joined him yet and you will have found out. After all he deserved a team of his own because he has experiences of a leader until he's gonna be a member of three teams for a while.

Also, I got Ultimate Chromastone from the 5 Years Later wiki.

Ben noted he and Sasuke's voices sound similar because they both are voiced by Yuri Lowenthal. Most of the characters share the same voice actors as Vegeta, Piccolo, and Zoro are voiced by Christopher Sabat. Trunks and Sanji are voiced by Eric Vale.

Anyway, in the next chapter Ben and the rest of Jump Force are gonna rescue and recruit new members.

Anyway, that is for now see you guys in the next chapter bye for now.
