Hello everyone and welcome back to another oneshot for the Ben 10 Crossover Roundtable/Multiversal One-Shot Theatre(depending on which one you read this on), the lace where I share

This is what I wrote for an attempt of a first chapter for a Ben 10 X Jujutsu Kaisen crossover inspired by Shinobi360's Ultimate Kaisen(go check that out if you haven't).

And seeing how I remained a bit stuck while writing this and how I don't know whether I'll make this into a fic or not...

I decided to post a bit of the introduction that I wrote for the (attempted) first chapter for the idea as a teaser/one-shot then see whether I'll do it into a fic or not.

So until I decide on what to do with the idea...the fic's release will be labelled as TBA(to be announced)

Withour further ado...enjoy.

"Heh! Yeah, you better run!" A teenage boy with brown hair and green eyes, wearing a green and black t-shirt with the number 10 in the middle of it and wielding a strange watch-like device on his hand, exclaimed with a smirk as he and two other persons were running across the roofs of Bellwood city, Chicago.

This was none other than the superhero star who saved the universe multiple times by now, Ben Tennyson a.k.a. Ben 10 and wielder of the device that allows him to transform into over 50 alien life forms…the Omnitrix.

One of the two persons who backed him up was a teenage girl with ginger hair put into a ponytail and green eyes, wearing a blue sweater vest and purple skirt. This was Ben's half anodite cousin, Gwen Tennyson.

The other person meanwhile was a tall teenage boy with a muscular build, messy shoulder-length black hair and dark eyes wearing a gray shirt and black pants. This was the osmosian boyfriend of Gwen and best friend of Ben, Kevin Levin a.k.a. Kevin 11.

The character they were all pursuing was a shady looking and off-putting person with yellow eyes, red hair and a zombified appearance wearing clown-like clothing and make-up who recently stole a brain from Bellwood's brain bank. This was none other than the energy vampire clown known by the name of Zombozo.

Seeing how his chasers would not let him go without a fight, the vampire clown laughed and made a run for it, leaping from one roof into another, the Alien Force close on his trail.

Gwen launched two pink mana disks towards Zombozo, but the clown extended his limbs and merely dodged the explosive energy disks, also launching himself into the air during the process then falling straight through a window belonging to a random office building.

Gwen whispered a spell under her breath and used her mana energy to create a slope so she, Ben and Kevin could get to where Zombozo fell without getting harmed.

Once the vampiric clown noticed the fact that the trio catched up to him prepared to flee once again, but before he could do so, a pink energy disk hit Zombozo's back, sending him plummeting to the floor and the brain in a jar that he was holding was thrown into the air, Kevin being the one to catch it.

"Really Zombozo?" Gwen asked the vampire clown in slight bewilderment at his most recent crime. "What kind of psycho steals from the brain bank?"

"...why does Bellwood even have a brain bank?" Kevin asked as flatly as he could, bewildered at the fact that a city(not just Bellwood in particular) had a brain bank. What use could a brain bank even have?

But while Kevin was dumbfounded by the fact of there being a brain bank in Bellwood, he didn't notice Zombozo elongating his arm and getting the brain jar back from the teen osmosian.

The creepy clown laughed as he got up from the ground and quickly said: "Thank you, my boy! A mind is a terrible thing to waste!" before running away and jumping out of the broken window he previously fell into.

Zombozo jumped into the streets of Bellwood right below the building, causing a whole lot of ruckus in traffic, including a truck almost getting smashed into a building and a car hitting a fire hydrant.

Seeing this, Ben's eyes narrowed and a frown formed on his face before he jumped down after Zombozo. While mid-fall, Ben smirked as he looked at the omnitrix on his right hand before scrolling through the alien playlists.

"C'mon...give me something good!" Ben muttered beneath his breath before slapping the Omnitrix's dial, in a flash of green, the teenage human known as Ben Tennyson transformed into one of the omnitrix's many aliens…Lodestar.

Lodestar was an alien with a metallic floating skull-like head with a golden eyebrow-like crest on its forehead, yellowish brown body with black stripes and crab claws-looking arms.

When the transformation finished, Lodestar landed right in front of the truck Zombozo had previously almost hit into a building.

"Lodestar? Not what I was going with but…I can work with this…" Lodestar muttered under his breath before noticing his best friend Kevin jump from the building and onto the truck. "KEVIN!"

"On it!" Kevin replied with a smirk as he used his osmosian powers to absorb the white metal the truck was made out of before jumping off of the truck and into Lodestar's arms.

Once that happened, the Biot-savartian used his magnetic powers to launch Kevin straight at Zombozo, knocking the vampiric clown to the ground, and throwing the brain jar to the ground once more.

"My brain! I'm losing my mind!" the creepy clown shrieked as he tried to get close to the brain jar, only for Kevin to round kick him from behind.

Kevin attempted to restrain Zombozo but the clown simply kicked the osmosian backwards, followed by launching himself into the air and crawling towards the brain jar.

Gwen was luckily there to intercept him and launched another wave of mana disks towards the clown, hitting him directly into the chest and sending him flying far away from the jar containing the brain.

Zombozo however grabbed a hold of the brain jar by elongating his arm once one. The clown prepared to run away only for Kevin tp have recovered from the last hit and attempted to kick the clown once more only for Zombozo to hit him in the face with the back side of the brain jar.

It seemed that Zombozo was about to escape but unfortunately for him and fortunately for the alien force…Lodestar used his magnetic abilities to attract the brain jar to him, with Zombozo desperately trying to cling into it only for Lodestar's magnetism to be stronger, taking the brain jar and knocking Zombozo to the ground, causing the clown to let out a groan before falling unconscious.

The scene then fades to the dawn of a new day, as Zombozo could be seen tied up and struggling to get free while Ben was talking to Gwen and Kevin, who looked ready to leave somewhere, without Ben.

"C'mon Gwen, you have to admit that I love this stuff as much as I do, right!?" Ben said to his cousin in an almost pleading tone voice "I can't believe you really wanna leave!"

"Yeah, well, when you skip a few classes, that means you have the brains for it…!" Kevin exclaimed as he launched the brain towards Ben.

Once the omnitrix wielder realized that a jar containing a brain was thrown in his direction Ben yelped in shock, somehow managing to catch the jar without dropping the brain or the ooze from within on the ground.

"There are plenty of colleges in Bellwood you could've gone to." Ben said towards Gwen in a last-ditch effort to make her stay and not leave to Friedkin University, who knows where.

"Umm…they're not quite the same as my ideal university." Gwen replied with a small cringe, causing Ben's head to drop, the teenage hero glaring at his feet in disappointment.

"I told you, we've spent years saving the world

…I just want to see something of what I saved." Gwen said as she approached Ben and put a hand on the shoulders of her doofus cousin.

"I know, I get it." Ben said with a nod before looking at Kevin with a smirk. "Well, better hurry back Kevin. Two bros is more than enough to take on whatever the universe throws at us, right?"

"I…I won't come back, Ben." Kevin stated to his best friend, not really wanting to break Ben's heart by breaking their bromance. "I found a place near the campus."

Once he heard that, Ben's emerald eyes widened in shock, realizing what that meant. It meant that…the Alien Force were breaking up.

"So…t…this is goodbye then?" Ben said in a badly attempted half-smile, really doing a bad job at hiding his sadness at the news.

"Of course not! And there are…holidays and semester breaks…besides, we're cousins!" Gwen said with a smile, attempting to comfort Ben about their imminent leaving. "It's not like we'll never see each other again…right…?"

After that, Ben and Kevin attempted to awkwardly hug each other like three times before opting for a fistbump instead shortly after. Through Kevin eventually decided to grab Ben by the neck and ruffle his head playfully.

"Don't do anything I wouldn't do." Kevin said towards Tennyson with a smirk.

"Count on it." The shapeshifting hero answered with a smile after Kevin let go of his neck.

"But…now that I think about it…don't do anything you'd usually do either." Kevin said in a joking voice, annoying Ben a bit and causing said omnitrix wielder to frown.

"Take care of yourself, doofus." Gwen said heartily after the hug between the two cousins ended.

"You do too, dweeb." Ben replied back at his nerdy cousin with a smile before Gwen and Kevin boarded the green and black car belonging to the osmosian and left Bellwood…leaving Ben to wave them goodbye with a neutral expression on his face, not really knowing what to do without his team now.

"What a touching moment!" Zombozo said with a laugh, causing Ben to turn around towards him with a glare. "Too bad you will never catch me by your lonesome!"

"Hey, watch it Zombozo!" Ben growled towards the vampiric clown as he approached Zombozo before continuing: "I don't need a team to get the job done. I'm a superhero!"

"I can do this alone, no prob!" Ben said as he glared towards Zombozo only to realize how crazy he'd probably look to an onlooker. Did he really get as low as to discuss things with Zombozo of all people? "I don't know why I'm telling all this to a crazy monster clown…"

"But first! Time to put my money where my mouth is!" Ben said as he puffed his chest onwards proudly before his stomach suddenly growled. "But first…time to put food where my stomach is…"

Soon afterwards Ben boarded his own green car and drove towards somewhere where he could get some grub for his tummy, and drove by Mr. Smoothies.

The omnitrix wielder stopped the car for a second to look at the Mr. Smoothies banner before shaking his head and saying: "Sigh…it wouldn't be the same…" before getting back to driving once more.

Eventually he stopped his car in front of a building known as Max's Plumbing where his Grandpa Max was working, though more accurately would be that he works beneath it in some ways…

Ben is seen entering Max's Plumbing,passing by some decorations and the counter of the building before heading towards the bathroom.

Once inside the bathroom, Ben looked at a rope hanging from the ceiling right over the toilet. As soon as he did that, a glowing green cycle formed beneath the alien hero's legs, soon afterwards the outside of the elevator is seen falling down the elevator shaft with speed, the omnitrix symbol being seen on both sides of it.

We see a head over perspective of the base of the organization known as The Plumbers, and before you ask, no, The Plumbers are not a toilet plumbing group and instead short for the Intergalactic Law-Enforcement Organization, right as a ship was landing in the middle of the room.

The elevator where Ben was is shown once again right before the elevator stopped and its door opened, bright green lights greeting Ben as he exited it.

The omnitrix wielder is seen passing by a group of Plumbers doing some things related to investigations and law enforcement before finally coming to a halt once he got to a seemingly dead end.

That wasn't enough to stop Ben however as he soon took note of an off-looking tile on the floor before tapping it and causing stairs to open down beneath his feet. Once Ben saw that happening a smirk formed on his face before he slipped down the railway before jumping off and running to a non-descript green room.

Once he got there, a person was seen walking in with a pot in their hands. Said person was a jolly, big and slightly round old man with graying hair and squinted green eyes wearing a red Hawaiian shirt with a light pink flower model on it. This was none other than the Plumber magister and the grandfather of Ben and Gwen, Max Tennyson a.k.a. Grandpa Max.

"Hey! Just in time Ben!" Max greeted his grandson with a jovial tone as Ben walked towards him, curious of what his grandpa could have probably cooked this time.

"What'cha making?!" Ben exclaimed with a smile, at this time, even Grandpa Max's cooking would be enough to satiate the omnitrix's wielder hunger.

"Belgorian Goulash! Want some?" Grandpa Max said happily as he opened the pot only to reveal a still-alive alien squid boiling within the pot, causing Ben's hunger to all but go away once the sight got to him.

The omnitrix wielder then gasped in shock as the squid alien from within the pot suddenly grabbed a hold of him and attempted to eat him alive through luckily Max was there to grab a gun from behind the desk and shoot a wave of lasers at the alien beast, causing it to let go of Ben and slide back inside the pot.

"How about it? Want some? It's ready to be served." Max said with a kind smile but Ben decided to wave him off by saying:

"Nah, Grandpa, I'm oddly…not hungry anymore." Ben said, waving his grandpa off before shrugging it off. "Well, I'll go back on patrol now."

"Ben, before you go!" Max exclaimed after his grandson, causing him to stop walking and look towards his grandfather. "I have something that may cheer you up!" The plumber magister continued as he started rummaging through one of his desks.

"I'm super careful!" Ben said, rolling his eyes. Why was everyone thinking he needed cheering up? He was a superhero!

"Besides, I'am so ready to get some superhero action up and running!" Ben said with a smirk as he flexed his arms to show off his muscles before his stomach growled once more. "And get something other than tentacle goulash for a meal for one thing."

"Well, that could be more than resolved in no time!"

Ben froze for a second when his mind realized that the voice that replied to his talking was not the one belonging to Grandpa Max but someone else instead.

It took a moment or two for Ben to register the fact that a mysterious man in his 20s with spiky white hair and fair skin wearing a bandanna covering his eyes and wearing a black hood and pants.

If the man's appearance wasn't enough to startle him, the man's way of speech certainly did. That accent sounded very distinctively japanese.

"Yo! You are Ben Tennyson-kun, riiiight?" The mysterious white-haired man in a sing-song voice, causing both Ben and Max to sweatdrop a little at the man's antics.

"Grandpa Max…who is this guy?" Ben asked his grandpa in the most flat voice he could possibly muster, curious as to who this weird guy was.

"Oh, Ben. This is Satoru Gojo, a jujutsu sorcerer. He'll be your superior from now on so please try to make a good impression." Came Max's answer, confusing the omnitrix wielder beyond relief.

"Okay…two other questions. First off, what is a jujutsu sorcerer? And second, what do you mean by "he'll be your superior for now" exactly?" The brown-haired teen asked his grandfather as two question marks appeared on Ben's face, showing his confusion in a comical manner.

"A jujutsu sorcerer is a person able to see and exorcise curses using cursed energy." Gojo stated bluntly, not even giving Ben the chance to register all that.

"I see…I don't get it." Ben said with a hand beneath his chin, clearly Satoru's explanation not getting

"Then…let's talk about this from the start should we?" Gojo chimed as he leaned against one of the desks in the room, a small smirk forming on his face.

"As I said…a jujutsu sorcerer is a person able to see and exorcize curses using cursed energy. Curses are spirits born out of the hatred and negative feelings humanity has sometimes. The stronger the hate and negative feelings a curse is born out of, the stronger said curse will be." Satoru explained to Ben.

"And I presume that cursed energy you were talking about…is it like magic and mana?" Ben asked the mt

"Oh, you are a perceptive one indeed, Tennyson-kun! It kinda is like mana in a way. While not related to mana, cursed energy does indeed work similarly to them. Think of cursed energy similarly to mana or a battery…it allows a sorcerer and curse to fuel their jujutsu. Jujutsu in this case being similar to magic in some ways, being literally a sorcerer manipulating their cursed energy into doing various types of skill and sorcery. Do you understand?" Satoru explained things to the alien hero before asking him if he understood, prompting Ben to nod his head.

"I understand but what I don't understand is…what does this have to do with me? And how exactly will you be my superior, Gojo-san?" Ben started asking but instead of Satoru being the one who replied, it was Max, taking Ben by surprise.

"Well, that is linking into what I had to talk with you about earlier…I enrolled you into the Jujutsu Tokyo Metropolitan High so you can become a Jujutsu Sorcerer."

"What?! Grandpa Max, you didn't even ask me about this!" Ben exclaimed at his grandpa, annoyance evident in his voice.

"I know, grandson. But if I was to tell you about this…I knew you'd probably refuse. Besides…this is a way to not only cheer you up, but also for you to go to school again and help the world in ways you can't from Bellwood." Max explained to his grandson, Ben was quick to try and counter his grandpa's point only for said old man to shut him up with: "Before you say that you don't need anyone to help you or that you're getting score at school regardless of going to it or not…this will help you, Ben. I'm not asking for much, just…try it for a month and then if you don't like it…then you can come back whenever you want. So…will you go, sport? I'm not forcing you to do this…if you don't want to…then that's alright too."

"Sigh…fine, Grandpa, I'll try. If you think it could help me following Gwen and Kevin leaving…then I'll try. But for a month only." Ben said with a defeated nod, causing Max to smile, satisfied. "But…how will I exorcize curses…or see them for that matter, Gojo-san? I am no sorcerer and I'm pretty sure I don't have any cursed energy for that matter."

"Please call me Gojo-sensei, Tennyson-kun. You'll be one of my dear students from now on!" Satoru said in a cheerful manner, causing Ben to sweatdrop a bit. "As for you not being able to exorcize or see curses…you can be a special case student. Your job will be to weaken curses enough so the other jujutsu sorcerers can have an easier time exorcizing them.

"Don't worry about not being able to see curses either. I have a student who has a similar issue to you, her name is Maki Zennin. To counter that lack of natural ability to see curses, Jujutsu Tech prepared some gear for the students with that issue." Gojo stated as he pulled some glasses and a small box from who knows where and showed them to Ben. "We have glasses that can allow you to see curses no problem. And of course…if glasses aren't your style, you can opt for these eye lentils instead."

"Uh-uh…sure thing…Gojo…sensei." Ben said awkwardly as he grabbed the box containing lentils from Gojo's hands before grabbing them and trying to shove them into his eyes. "Where will I meet the other students?"

"Before I tell you that, I think I should tell you the names of the other first years…Megumi Fushiguro, Yuji Itadori and Nobara Kugisaki." The white-haired jujutsu sorcerer stated, prompting Ben to nod. "You'll meet them later today. The meeting point will be Harajuku, Tokyo. I'll meet you and the other students too in that region."

"Alright…then…?" Ben muttered but before he even realized what was happening…Satoru Gojo was already gone. "...where did he go?"

"I think he left, sport. Guess you'll have to get to Harajuku." Max replied to his grandson in a flat voice.

"Oh. Wait…how do I even get from here to Harajuku?" Ben asked himself, seemingly forgetting the act that he has multiple aliens that could get the job done.

"You have XLR8, Fasttrack, Stinkfly and Jetray, don't you, sport? Use one of them to get them to get there." Grandpa Max sweatdropped at his grandson's negligence on the situation.

"Oh, right. I sometimes forget I have the most powerful weapon in the universe that allows me to turn me into aliens on my wrist…thanks for reminding me, Grandpa!" Ben said with a smirk before clicking the buttons in the side of Omnitrix's dial, causing said dial to pop up and reveal a series of hologram heads. After he got to a hologram that he liked, Ben pushed down the dial and in a flash of green…in his place stood the humanoid red manta ray alien…Jetray.

"See ya around Grandpa Max!" Jetray said with a smirk before taking off straight through the room's roof, much to Max's shock considering that the exit to the room was right there….
