There will a lot ships for Ben.
Ben's Omnitrix from Omniverse will have both the Ultimate and Omn-Kix and Omni-Enchanced functions.

Chapter 1:A World of Heroes
Bellwood
In a warehouse Ben, Gwen, Kevin and Rook along with Blukic and Driba they found Dr. Psychobos along with projector that the dumb Galvans were working on. They say that the machine was set to a world of heroes.
''Give up, Dr. Psychobos.'' Ben told the psychotic Cerebrocrustacean.
''Yeah, give back our Multi-Interdimenisonal Doorway.'' added Driba.
''Besides it haven't been test it, yet.'' stunned Blukic.
''Really? Because where I'm standing. you are where I want you.'' said Dr. Psychobos.
''What you do, Psychobos?!'' Ben yelled at the scientist.
''My ultimate plan! To be rid of your per-sistent annoyance!'' explained Dr. Pyschobes. ''With the Galvans' machine will you get suck into a new dimension, and I'll will be rid of you.''
''You're insane!'' shouted Gwen.
''Yes, but with that. I can begin again. And I use the term loosely.'' replied Dr. Pyschobes, then started laughing, but not before getting stuck in a net. ''What?!''
Rook fired a net from the Proto-Tool, making the crab alien incapacitated. ''Ben, what will we do?'' he asked.
The machine starts to spark and overload.
Ben had an idea, but he thought that it was risky, but he had to it.
''I have a plan.'' Ben told Rook. ''When I run and stop the machine, shoot it.''
''What?! But that could suck in, Ben!'' cried Gwen.
''I know! But it's the only way!'' said Ben, turning into Upgrade. ''We have on chance!''
They all nodded, knowing it is the only chance they had. Upgrade turned the machine black with green circuitry. Upgrade tried to spot it.
Everyone was silent as the machine, and Upgrade were gone. Gwen, Kevin and Rook stunned as he was gone.
''Well, that ain't good.'' responded Bluckic.
''Where did Ben go?'' Gwen asked the Galvans.
''Well, if our calculations are correct, he will arrive in the last world the world finder found was set on.'' stated Driba.
''Well, cant you guys make another one to bring him back?'' inquired Kevin.
''We'll try, but it will take moths of research and experiments to make it work.'' reported Driba.
''Well, I hope Ben will be fine, in that world.'' said Max sadly as he and the other Plumbers arrived. He and the others hoped Ben wouldn't get in trouble.
Unknown Earth
Ben as Upgrade, got up groggily. He didn't know how long he was out.
''Oh man, how long I was out?'' he asked, then checked his surroundings. He woke up in an alleyway. ''Great.'' He turned back to Ben.
He got up and saw the MIP was destroyed. He groaned at the destroyed machine.
''Great, now I'm in a world I don't know. Just wished Professor Paradox was here to help.'' said Ben hopefully. ''Might as well check out this world.''
Ben walked the alley and tried to find a way out. As he walked, he needed to get an understanding of the place he was in.
''Blukic and Driba said that was a world of heroes. So, if there are heroes, then I can tell them who I am and maybe they'll let do my thing.'' he thought as he found a way out.
He got out of the alleyway and saw many buildings and such. He walked down the sidewalk trying to see where he was. He saw words on the buildings judging by them he was in Japan.
''I'm somewhere in Japan. I hope that I can help the heroes in a world full of superheroes. I always there other heroes back in my world.'' thought Ben.
Ben keeps walking to find information about this world. He had no money or anything. Before the teen hero keeps walking until a person walks past him.
Ben looked at the person it was a boy with a short mess or fluffy dark-green hair and large and somewhat circular dark green eyes. He was a button black jacket uniform and black pants. The green haired boy was carrying a note book in his hands. Until it slipped from them.
Ben looked down and grabbed the note book. He begins to walk up to the boy.
''Hey buddy, but I think you dropped this!.'' called out Ben.
The green haired boy turned around to the teen hero and noticed his notebook was missing in his hands. ''Oh, thank you so much I must dropped it when I was walking to school.'' smiled the boy.
''You're welcomed. I'm Ben Tennyson, by the way.'' Ben introduced himself.
''Nice to meet you Ben, I'm Izuku Midoriya'' introduced the green haired boy now Izuku. ''You're not around here, are you?'' he asked.
''What gave it away?'' asked Ben jokingly.
''You're from America.'' replied Izuku, then he looked at his phone. ''Oh no! I'm gonna be late for school! And I have to be there in 20 minutes! I'm going be expelled!'' he cried.
Ben felt bad for him. Then he had an idea. ''How about I help you?'' he offered.
''Really?'' asked Izuku.
Ben nodded. ''Yeah, I've always helped people in need. Just leave to me.'' said Ben turning on the Omnitrix.
''What's he doing with his watch?'' thought Izuku as Ben searched through the watch's playlist. Just as he picked something, the ground started to shake.
''What's happening?'' inquired Ben.
Then they saw a really big guy fighting down people on a railway. There was a large crowd of people watching.
''Alright! We got some heroes to help us!'' yelled one civilian.
''Get him!'' shouted another at the people.
''Whoa. Who are those guys?'' questioned Ben, getting a surprised from Izuku.
''What? How do you not know who they are?'' he asked, flabbergasted at the teen hero.
''You said so yourself, I'm new around here.'' Ben reminded him how they met.
''Oh. My bad.'' he stated. ''Well, those guys fighting that guy are the Pro Heroes.'' explained Izuku, pointing to the costumed people.
Ben looked at where the green haired boy pointed. There he saw a few that made him think of what his alien forms can do.
One hero was a tall and muscular man, who wore a caution patterned headband, a shirt that was opened in the middle, exposing his torso and abs, gauntlets on both of his arms, a belt with the same color and blue pants with boots. He held a broken train light.
''Wow! Way to go. Death Arms!'' exclaimed one civilian.
''Death Arms? Kinda scary name for a hero.'' thought Ben. ''Though, Ghostfreak is also a scary name as well.''
He then saw another hero, this one looked like a firefighter, expert for the cannon from his back, a white mask on his face, red tape on each of his arms, and yellow sneakers. He made a water perimeter along where the people were watching.
''Everyone, please stay back! This area is far too dangerous.'' he remarked.
''Whoa, The Rescue Specialist, Backdraft is here? He'll make sure we're okay!'' proclaimed a civilian.
The two boys walked up to the crowd, where one guy was talking to another about the bad guy going full monster in the middle of the city.
''Wow. Those guys are pretty good.'' commented Ben. ''Those they don't compare to what my aliens can do.''
''Yeah, aren't they amazing? I've always wanted to be a hero, just like them.'' reported Izuku, getting Ben's attention.
''You want to be a hero? That's a pretty good dream.'' said Ben to him. Then he saw he had a sad smile. ''What's wrong?'' he asked.
''It's just...my dream won't be a reality any time soon.'' Izuku told him. ''You see, I wasn't born with a Quirk.''
''Quirk? What's that?'' asked Ben, not knowing what he meant.
''You don't know a Quirk is?'' demanded Izuku. ''You don't keep up with the news, do you?''
''No. Not much as I watch over shows on TV.'' replied Ben. ''Can you tell me about these Quirks?'' he asked.
Izuku sighed. ''Quirks are special powers that people are born with. 80% of the world population are born with Quirks. The 20% aren't born with them.'' he explained.
Ben went wide eyed. ''Born with powers? So this is a world of heroes.'' he thought.
''I wasn't born with a Quirk, but that won't stop me form achieving my dreams of helping people!'' responded Izuku with determination in his voice.
''Wow. She sounds like me when I had first used the watch.'' thought Ben, knowing he will achieve his dreams somehow.
Then they saw another hero come in to join the fight. This hero wore a blue jumpsuit that had a wooden belt, knee pads, and shoes. He also had rose veil hanging from his left side.
Then a group of fangirls squealed at the hero. ''It's Kamui! We're your biggest fans!'' they cheered.
''Who's that guy?'' Ben asked Izuku. ''These hero names are a little better than my alien names.''
''That's Kamui Wood. He's the newest hero on the scene.'' stated Izuku.
''Seriously? Death Fist? Backdraft? Kamui Wood? Do they really call themselves those names?'' asked Ben.
''Yep! They are proud to be called by them, because a hero is not a hero without a name.'' explained Izuku.
The villain gets angry and tries to hit Kamui. Ben then thinks about the abilities.
''So, most of the heroes have many abilities like my aliens. And they all call themselves by what their powers.'' thought Ben, looking at the fight.
''Assault, robbery, and the illegal use of powers during rush hour traffic. You are the incarnation evil.'' Kamui told the villain, which made Ben think.
''Really? Illegal use of powers? This world is seriously different.'' thought the teen hero.
''Yeah, most people with Quirks used them for doing bad than good.'' said Izuku.
Kamui then spread his arms to many branches. Izuku gets excited for this. ''There! His special move! The Pre-Emotive...''
''...Binding!'' continued Kamui as his arm branches grew bigger.
''Lacquered Chain Prison!'' said Kamui and Izuku at the same time, his arm branches were to blind the villain when suddenly...
''Canyon Cannon!'' shouted a female voice as a giant suddenly kicked the villain off the tracks. Everyone was surprised by this, even Ben.
''What the what? Who'st that?'' Ben asked Izuku.
''That's Mt. Lady. She's a new hero too, with her Quirk Gigantification.'' Izuku told Ben. ''It's makes her grow big to attack bigger opponents.''
''Kinda like Humungosaur and Way Big.'' thought Ben as he saw her. She went back to normal size and saw that she was hot. Her suit didn't leave much to the imagination: a skintight purple and cream colored bodysuit with orange stripes. She also a domino mask with brown protrusions on the sides.
Ben had no idea women would look like this in any world. He just hoped no one does something.
Meanwhile
Unknown to him, someone was watching. The person was not pleased by his subordinate's failure at a simple job. It, he was glad that one person saw the fight.
''So, Ben Tennyson is in this world, at last. Time for the hunt yet again.'' chuckled the person as he whistled for something.
Back with Ben
Ben was silent as he felt the ground shake faintly. ''There is something under us.'' thought Ben.
''Ben, are you alright?'' asked Izuku. He saw that his face spoke fear.
''Izuku, listen.'' Ben told him, getting to the ground and putting his ear to the concrete.
''What's wrong?'' inquired Izuku, not knowing the thing was coming up. He reacted quickly.
''Get down!'' Ben told him, getting him and ducking away, while a giant monster came up and roared.
Everyone, including the heroes and the villain, were surprised by this monster.
''What the hell is that thing?'' questioned Death Arms. ''Kinda looks a centipede of sorts.''
''Actually, it's a Terradino Centipeedle.'' answered a voice, making the heroes turn around. ''A rather nasty creature to utilized, but its usefulness can be fully utilized...when it has a full stomach.''
The villain gasped at who it was. ''Boss, I can explain.''
''There are no excuses for what you did. You were supposed to keep them away, but I guess it was too much. Now, it's feeding time.'' said the person as he whistled for the Centipeedle to come.
''Mr. Khyber, no! please, give me another chance!''' begged the villain the person's name as one of Ben's enemies.
''Khyber?! That's impossible!'' thought Ben, thinking it was impossible for one of his enemies to be here.
''No second chances.'' scolded Khyber, removing his cloak, revealing him wearing bone armor, and having four holes in his jaw. ''Now, you're my pet's food.''
''No!'' screamed the villain, running away, But it was futile as the Tyrannopede shot a string webbing at him, then getting pulled by the alien predator as him mouth open and the villain screamed as he was swallowed by him. Everyone was scared now, except for one person.
''Khyber! What and how did you get here?!'' yelled Ben, making everyone look at him.
''Ben Tennyson.'' said Khyber, jumping in front of the crowd. ''Eon said you would come sooner or later.''
''Eon is here? Now I get it. You're still upset that your greatest prey in the universe slipped through your fingers.'' Ben taunted him.
''You are still my prey. But now, this world is my new quarry. And soon, you'll be my trophy.'' finished Khyber, while whistling his new pet to stand up to him this time Khyber has a new Anbuian Baskurr a male one. ''Have fun.''
Khyber teleported away, causing Ben and Tyrannopede to stare at each other. The centipeedle glowed at the teen hero, not completely full. Ben smirked at him.
''Ben, get of here! You'll be eaten!'' Izuku told his new friend. Ben smiled at him, a smile that said. ''I got this.''
''Don't worry. I fought this guy before. I can do it again.'' Ben told him, activating his Omnitrix. He scrolled the playlist as he found the alien to use. ''It's Hero Time!'' he shouted out his catchphrase. He the slammed the dial and was bathed in a flash of green light.
