Welcome to the second chapter of this story! I thank all of you who liked it, commented and followed, it means a lot to me.

Responding to one concern from some of the reviews from :

While it is true that Ben has more powerful alien transformations than some of the quirks from MHA, there are some quirks that would be EXTREMELY benefitial for Ben to have, I'll give you all an example: Goop vs. Mina. Goop has advantages like flight and being able to morph himself, but he also can't win a straight up fight against anyone because he can't punch anything, and also, his projector is a VERY BIG weakness. Meanwhile, Mina has the same acid abilities as goop, but not only can she win in a fight, she also doesn't have the gravity projector AND her acid can actually go to other people (those who saw the 23rd episode of this last season know what I'm talking about).

With all of that said, enjoy!


CHAPTER 2: Hero From Another World


-Unknown City-

Confusion was the only thing in Ben's mind at the moment. The more he ran in the street, the more confused he got. The buildings and the environment looked from Earth, but the people were... strange, if that was the right word. Most of them looked human enough, but some had distinct features, like blue skin, animal body parts, unusual things for hands, etc. But the actual weird thing about it is that he didn't recognize any of them as alien species. -'Maybe that's why the Omnitrix keeps saying there's new species in the area'. So either there's a full catalog of aliens that came JUST to this modern city and both them and the city hid it all from the world, or they were something else. But he shouldn't pay much attention to that at the moment. Right now, he has a job to do.

As Ben arrived at the explosion site, he saw that it looked like a gas station where the bombs had clearly been what had exploded. Unfortunately he couldn't arrive any sooner since he was locked out of the Omnitrix while it was still analyzing the DNA in the area. Ben heard someone coughing inside the gas station's smoke and spotted a 50-something looking man stepping out of it. Taking priority, Ben ran to help the man.

-"Are you okay?" Ben asked worriedly, helping the man to get away from the smoke and sit on the edge of the sidewalk.

-"Yes... I'm fine, thank you my boy." he said, still a little breathless.

-"What happened ?"

-"Three thieves... They wanted the money from the register. I managed to press the emergency button to call for help and I kept trying to stall until the police or some local hero arrived..."

Ben wondered in his mind if heroes were common here in this city and if they would know who he was. They should know him of course, he was the most famous hero in the world for a reason, but decided not to ask the man that as he had more important matters at the moment. The young man then went back to paying attention to the man's explanation.

-"...But they realized that and their leader used his quirk and tried to shoot me. I figured that out and dodged it in time, but I think the bullet ricocheted behind me and hit one of the gas pumps. Luckily the explosion didn't knock the store down on my head."

-"He used his what?" Ben asked, confused. But before the man could explain further, the two heard sounds of someone coughing and getting up. It was then that, with the smoke already clearing, they saw the three thieves getting up and recovering from the explosion. As the store clerk said, the group wearing face masks were being led by a guy bigger and stronger than the other two put together. Definitely enhanced or a mutant.

Instantly, Ben drew their attention to him. -"Hey!"

The three raised their heads and saw the teenager calling them. They started to realize what happened and instantly tried to run away from the scene.

-"Come Back here!" Ben screamed at them, but they ignored him. He went back checking to see if the man was okay enough to leave him while he went to chase and catch the robbers and asked: -"Was anybody else in the store with you?"

-"I don't think so, no, just me and the thugs."

-"Alright, you stay here, I'm gonna ask for help..." Ben got up and looked at the end of the street where the thugs were running at: -"... and caught those guys."

The man heard him say that right before Ben started to run and tried to stop him -"Wait what? Don't go after them! Wait here for a Hero to show up!". It was useless, Ben had already made up his mind, and nothing was going to stop him now.

Meanwhile on the thug side of things, who stopped running after a while to make sense of the situation and try to decide what to do next:

-"I told you we should have gone after a simple store!" screamed one of the robbers, who had red hair, at the other.

-"Everyone knows that gas stations have the most money due to the prices!" argued the other one, with blue hair.

-"But everyone pays with their cards, not their fluid money!"

-"And the people that go to the simple stores don't?!"

-"SHUT UP! Both of you are idiots!" The big guy had enough and shouted at the two. He was almost the size of two men. Weirdly enough, in the place of his right forearm and hand, was a rotating gatling gun. They had all taken their masks off to catch some air and you could see a small scar on his chin. "Let's just get out of here before a Hero shows up!" All three of them started moving again, making turn after turn on the roads and alleys.

-"Or before you get angry and shoot someone again..." whispered the redhead.

-"If you keep talking, that might be you!" The big guy shouted, getting frustrated already.

As soon as the three turned another corner into the alleyway, they heard a voice shouting at them from behind. "HEY!"

They all turned back and saw a teen, no more than 16 years old, standing on the exit of the large alley they just went from.

-"You boys really need to learn not to shout when trying to run away." said Ben sporting a smirk on his face while crossing his arms on his chest.

-"HAHA!" laughed the big one out loud, clearly not knowing who he was dealing with -"You think you're hot shit, don't you boy? You ain't no hero, don't try to stop us!"

Right then, the Omnitrix returned to its natural green color. While still not in a fight, Ben took the opportunity to put to rest a question he had since dropping in this city...

-"Do you know who I am?" Ben points to the symbol on his watch: -"And do you know what this symbol is?"

-"What?" The big guy asked, confused -"I have never seen you in my life! Nor that green symbol, whatever it is!"

Ben looked at the faces of the other two criminals in front of him, and they were just as confused as this guy was. That was all the confirmation he needed to know he was not on his Earth anymore. Either this was an alternate timeline or an alternate universe, maybe even Rex's universe. But no option sounded good for him in the long run.

-"Alright, so how about you stand down peacefully so I don't have to beat you guys up?" Ben asked with a serious face.

There was a pause.

-"HAHAHAHAHAHAHAHA!" Booming laughs were heard from the three thugs. -"You really think you can beat us, kid? You must have some sort of brain damage! HAHA" said the big man as he continued to laugh.

Ben started thinking about his possibilities in this situation: -'Ok, he has a gun for an arm, that's probably what he used to shoot the clerk. What did the man say it was again? A... quirk?' He slightly shook his head to focus -"Doesn't matter right now, I need to choose someone very strong and bulletproof just in case".

-"Well... I tried to argue" said Ben with a smirk. He brought his hand to the Omnitrix, opening it's face plate, rapidly choosing the alien he thought the best and slapping the watch.

The three thugs had to cover and close their eyes for a moment due to the immense green light emanating from the boy. When it died down, what they did not expect to see in the young man's place was a tall red creature with four arms. He was almost twelve feet tall with red skin, has four green eyes to go along with his four very muscular arms. He was also wearing a black tank top-like shirt with one large green stripe in the middle, black pants, a green and white belt where the watch's symbol was located, and black fingerless gloves with green cuffs at the wrists. The creature shouted his name to incite fear into the criminals in front of him: -"FOUR ARMS !"

-"So..." The Tetramand form of Ben slapped his fists into the palms of his hands, generating a thunder sound to get the attention of the thugs. -"Which one of you want to go first and show me what this world's criminals got ?" He smirked at them.

The big man shook his head to get out of the shock -"SO WHAT?! Just because you got a good quirk you think you can play hero with us kid?!" He shouted while slowly approaching Four Arms, who tensed up, ready to fight him. -"Let me tell you something kid! If you even think I'll let some wannabe Hero throw me back to jail..." He started raising his felt arm up, preparing a punch -"Then you have NO IDEA WHO YOU'RE MES-" SMASHHH!

Whooooooosh, CRASSHHH!

Ben didn't even let the man finish his sentence before punching him with his two right hands straight in the face, with enough force to throw him until he crashed to the wall at the other side of the alley!

His two friends were stunned beyond belief! They didn't know what to do against someone that strong! They kept looking between Four Arms and the groaning body of their leader. Eventually, the one with red hair took action and... aimed his hair at Ben. Out of the hair, hot lava started shooting from it going straight for Ben, but with quick reflexes he was able to dodge it.

-"Lave hair? That's a new one." Ben stomped, sticking his foot on the ground and clapped with both pairs of his arms, creating a shockwave that sent the lava guy crashing into the same wall as the big one.

-"HEY!" The blue haired guy screamed -"That was my brother! Take this!" He aimed his hair at Four Arms as well and started shooting high-pressured water at the alien. But just as Ben expected, it didn't do much, it wasn't even as powerful as Water Hazard's pressured water. The Tetramand simply raised one of his arms to block the water while walking closer to the thug. When he was closing in, he saw that the lava guy was getting up as apparently that shockwave wasn't enough to take him out.

Groaning, the lava hair thug stood up and saw that his brother was easily getting overpowered by Four Arms, so he did the only thing he could and prepared to shoot his lava at him. Unfortunately, Ben saw it coming from a mile away and already had an idea. As soon as the lava started coming at him, Four Arms grabbed the water guy really fast by the torso and aimed his head at the lava, making the water collide with it and even continued going, generating a massive curtain of steam between Ben and the Lava guy.

The red haired man screamed when the water hit his head due to how fast it was going. His hair was now trapped in a thin coat of solid rock. And he couldn't see anything beyond the steam even when squinting his eyes. Before he knew it, something large was thrown at him at such a high speed that he didn't even had time to react to it. He was sent crashing into some nearby trash cans, hitting his head hard on them and rendering him unconscious.

Four Arms got close to the man to see if he was down and smirked as soon as he saw him on the ground, and right beside him, his own brother with some of his hair missing due to some of the lava having landed on it while still hot.

-"I knew it would work!" Ben raised his fist in victory. But it was short lived as he heard some rumbling behind him and saw that the big man, their leader, was getting up and ready for a fight.

He got up and dusted off his clothes -"You think you can knock me out that easily huh?" Even though he said he was tough and looked a little dazy, he looked Ben straight in the eyes -"But I'm not like those two idiots!" and raised his right arm, the one with the gun aiming right at Ben -"I actually trained for this kind of fight! TAKE THIS!"

Four Arms instantly made an X with his arms, right when the gun of the large man's arm started to actually fire bullets from it!

Lucky for Ben, Four Arms had bullet-proof skin, but he could still feel the pain from the bullets... as little as it was.

Four Arms then stomped hard on the ground, creating a big shockwave, just enough to actually lift some of the cement off and to disbalance the leader so he could fall.

-"You may have trained for this..." He stuck all his hands on the ground that was loose and started pulling on it, with enough strength to rip a large boulder and lift it over his head -"... but I nothing beats experience!"

And he threw the boulder at the man, hitting him right in the head first, making him go flying again to the wall, destroying it completely and burying the guy in a pile of bricks and cement.

-"Oops! I might have gone overboard a little." Ben went to check if he was alright and sighted as soon as he heard a groan.

-"Oh thank goodness." He looked inside the wall he had destroyed and saw it was the corridor to an apartment building, and there was one old lady looking at him with fear.

Four Arms tried to calm her down -"Sorry for the mess ma'am, didn't mean to disturb you" he awkwardly said while scratching the back of his head.

-"You!" he heard someone from behind him. Ben turned around and saw a man whose arms were made out of wood, with a wooden mask covering his face with only his eyes visible. He was also sporting a dark blue bodysuit and large wooden shoes and belt.

The man spoke in a demanding tone of voice -"Surrender now villain, before I make you."

Ben wasn't really sure who this guy was, but from the sound of it, he could be one of the heroes this world has. Trying to defuse the situation, Ben opted to talk to him: -"Look, this were the bad guys, I was just stopping them." He pointed at the two brothers on the ground. -"Maybe we can talk this ou-"

The hero interrupted -"If you really are a Pro Hero, probably a new one since I've never seen you before, could I see your license ?" He questioned, still very much prepared to fight the four-armed man.

-"Uhmm... a license?" Four Arms asked while scratching the back of his head. -"OH, of course!" He said trying to play it off. -"You see I uh... forgot mine... at home. If you let me explain it, maybe go run and grab it, then we can forget this whole thing?"

Ben really hoped that excuse was believable enough for the pro hero. Unfortunately for him, that's not how things worked here.

-"If you don't have a license, then either you're indeed a villain or an illegal vigilante." said the hero. -"In which case..." he got into a fight stance "...I'll have to bring you in nonetheless!"

Before Ben knew it, the Pro Hero produced tree branches from his arms that wrapped around Ben to capture him. But Four Arms is way stronger than people realize and with some effort broke free from the wooden prison. He didn't waste any time and started running away from the scene, not wanting to beat up a hero in the first hour of being in this new world. He already committed that mistake once.

The Pro Hero immediately started chasing him 'I need to get this guy off my trail, I don't want to end up in a prison. Or in Area 51'. Ben kept running, going from alleys to streets, eventually crossing roads, but the hero was still following him. To have more of an advantage, he jumped into the air high enough to safely land on a rooftop.

Four Arms continued jumping, each jump allowing him to cross full city squares in distance, from rooftop to rooftop, rarely looking back to see if the hero was still behind him. After a great distance and what it felt like ten minutes, Ben saw that no one was chasing him anymore. He took a moment to relax, but it really only lasted a moment.

BOOOM!

Just when Ben thought that he was safe from the wood man, a new guy landed right in front of him, cracking the ground a little. He was a very large man, extremely buff, even more so than Four Arms, with a well-defined physique. He had short blond hair, swept backwards, with two distinct tuffs that stick up above his head. He was wearing a largely blue bodysuit with red and white accents, while his sleeves and boots were gold in color.

This... mountain of man looked at Four Arms with a wide smile -"Well, well, well! You seem to be running from something, may I know what it is?"

His voice boomed, radiating confidence and power in a scale that Ben has ever seen once or twice in all his life! He was shocked by this, presumably, "human" man, though not for a long time, since the whole situation got interrupted when the Omnitrix started beeping and flashing red.

-"Oh no." Were the only words that could come out of him before a great red light erupted and he transformed back into his true form.

The new guy closed his eyes and used his hands to block the sudden flash of light, but as soon as he opened them, what was in front of him was not the tall creature he had seen moments before, but a teenage boy with a green jacket and blue pants.

Confused, he asked -"Were you the one causing trouble at the gas station? You're just a kid, shouldn't you be in school to make better use of your quirk?"

Ben could only stare at the man with a growing frustration with the Omnitrix impeccable sense of bad timing. Looking better at him now, he recognized the man from a few posters he glimpsed while running towards the gas station. 'So he's a famous hero. Let's see if this one can help me,' thought Ben.

He took a deep breath -"So... hi. I know you're probably just as confused as I am right now. I don't know where I am exactly, I just saw an explosion, some robbers and I couldn't simply ignore it. I'm sorry for any trouble I've caused, I just want to go back home."

A little confused by the teen's answer, the hero asked: -"What is your name, young man?"

-"Ben. Ben Tennyson."

'An American name' The hero thought -"Do you know the name of this city?"

Ben shook his head -"No. I just kind of... woke up in here."

The large man stared intensely at the boy in front of him, analyzing to see if he was lying or not, before giving his honest answer: -"Hmm, alright, I can take you to a police station, I know someone who can help."

While Ben didn't exactly vibe with the idea of being questioned by the police, since the Omnitrix decided to time out and he was sure he couldn't outrun this man, there weren't a lot of options right now.

With a heavy sigh, Ben agreed to be taken.

-"Well, alright, but can we keep this on the down low? I don't want the news involved."

The hero raised an eyebrow -"Why not?"

-"I... have my reasons. I can explain it at the station." said Ben, hoping to have more time to actually think of a cover story.

It seemed to work, as the man paused for a few seconds and put his hand on his chin to think it over, but did agree to it.

-"Fine. But I cannot control the press if they do see you."

Ben sighed in relief, glad that the hero could help him without attracting attention to himself. -"Thank you hmm...sir. What was the name again?"

The behemoth of a man then got closer to the young hero, extended his hand and bent his legs. -"My name's All Might, and I'm the number 1° Hero! Now let's go!"

Ben wasn't sure what the large man was going to do, but he took his hand, feeling he could trust this guy.


-Police Station-

What the young hero did NOT expect however was to literally be carried by the large man while he jumped in the air to the station. But Ben got used to it after the initial shock, since he himself was used to flying, or in this case jumping really REALLY far.

When they landed, Ben finally saw what he assumed was the name of this city on the police station sign: "MCPD: Musutafu City Police Department"

He definitely never heard of a city called "Musutafu", and he would have if there were as many aliens on here as there were on Bellwood. IF they are aliens to begin with.

All Might then escorted Ben to a back door. While doing so, he pulled out his phone and typed into it, indicating he's messaging someone. They entered the building and All Might led the boy inside an interrogation room. While Ben hesitated a bit on entering, he still went inside and sat firmly on the chair, waiting on the man the pro hero had called, while said hero was leaning on the wall.

-"Don't worry young man, the officer I called is the best I know." The hero said in a comforting manner.

That did not put Ben's mind at ease however.

Maybe 10 minutes passed when the door opened and from it came a tall man with black hair and rectangular black eyes. He was wearing a tan overcoat and matching hat. Underneath the coat, he wore a black suit and a green tie.

The man looked at All Might and asked -"Is this the boy that caused all the trouble?"

Ben looked almost offended by the question! -"HEY! I didn't cause ANY trouble, I just stopped some robbers from escaping!"

The new guy saw All Might nodding. He sat in front of Ben, opened a paste, took his pen and started writing on it. -"Hello." His voice was calm and collected. -"I'm Detective Naomasa Tsukauchi, from the Mustafu Police Department. And you are?"

-'A detective? Shit, I thought he would just call in a regular officer. I have to be even more careful with what I say now.' Ben thought. He couldn't reveal so much about himself, ESPECIALLY that he was from another universe, they probably wouldn't believe that and just try to throw him out into a psych ward. Or worse. This wasn't like Rex's Earth. This universe had WAY more superheroes than Rex's and Ben really didn't want to fight his way out against multiple fellow heroes.

-"My name is Ben Tennyson."

-"How old are you?" asked Naomasa.

-"I'm 16 years old."

-"Alright…", the detective dropped the paste and looked right at Ben. -"I am told you have something to explain about the situation regarding the explosion at the gas station?"

Ben lit up his eyes and looked at him with a more determined expression -"YES!" He took a deep breath and started explaining it all: "I was near the gas station when it blew up. I ran to check to see if anyone was hurt and I found the cashier. I helped him up, asked what happened and he told me that three guys were robbing him." Ben pointed to his arm -"One of them had a gun for an arm and apparently he shot the cashier, but the bullets ricocheted and hit the open gas pump. I saw the three guys running and chased them to a corner. They weren't going to surrender so I used my… power to knock them out, very easily by the way, but a soon as I was finished with them, this other guy, I think he was a hero-"

The detective interrupted Ben: -"Wait, are you talking about Kamai Woods? He was close to the scene and I just got a call from him, reporting chasing one criminal or vigilante across the rooftops.

Ben threw his arms up and exclaimed -"YEES! That was me! But I'm not a criminal, I just stopped those guys and he tried to arrest me because I didn't have, what he called, a hero license!"

-"Well, you're not from this city are you?"

-"No. I… I'm kind of lost here."

-"Are you perhaps from the U.S.?" The detective guessed from the American name.

-"Yeah, from… a very small city there." 'So far, so good' Ben thought.

-"Do you know how you got here? Perhaps a criminal in your city had a teleportation quirk?"

The young hero looked at the detective almost in a grateful way, he just gave Ben the perfect excuse to this whole thing! -"Y-Yeah! That was it! Some weird guy with portal powers. I was fighting him and his gang. He must have sent me here to get rid of me."

Naomasa raised an eyebrow at the young man. -"Do they have different laws in your state? For you to be fighting crime without a license."

Ben rubbed the back of his head, trying to think of an excuse. -"W-Well, it's a very small city. Very Secluded. The laws are a little different."

Unfortunately for Ben, what he didn't know was that Detective Naomasa also had a power. The power that allowed him to become the great detective that he is today.

The power to know when someone is lying.

He's been using it since he entered the room and right now, he knew Ben lied to him. He wasn't from a small town, nor was he fighting a villain with teleportation abilities, or any kind of villain. He was hiding something, either to protect himself or someone else. Naomasa would get to the bottom of this and he would have to pressure the boy to do so.

The man turned around and looked intensely at All Might for a few seconds.

All Might seemed to get the message. The boy was lying and Naomasa needed some help to see what he was hiding.

The hero stood beside the detective, looking sternly at the boy. -"My young man… I think it's better if you tell the truth."

-"W-What do you mean?"

-"We can see that you're lying." said Naomasa -"We just want to help, but we can't do that if you don't tell us how you really ended up here."

Ben didn't really have an answer for that. How did they find out? Was he that bad at lying or just really nervous at the moment? He didn't know. Maybe he just sounded too uncertain about the story.

-"I'm telling you the truth, I swear!" Ben exclaimed, trying to make them believe his cover story as much as possible -"What do you want me to say here?!"

-"The truth." said Naomasa with conviction; -"About why and how you, an American kid speaking perfect Japanese, ended up being chased for not having a hero license after stomping three criminals with ease."

-"Wait, Japanese?! Am I in Japan right now?!" Ben didn't even realize that he was speaking another language, for him, everyone was speaking english. It must have been the universal translator on the Omnitrix doing it for him.

The big hero then spoke, with a soft and concerned tone -"Please, young Tennyson. We just want to help you."

Ben was conflicted. Stuck at a stalemate. He didn't want to fight or run from these two, that would just paint a target at his back for the whole police to shoot at. He did that with Rex and his team, and the only thing it created was trust issues. If he wanted to get back to his own world, he needed people he could trust and an ACTUAL cover story this time if needed.

The teenager carefully looked at the two men in front of him that were just trying to be nice. A hero and a police detective were a good pair to start learning about alternate worlds. He made up his mind.

-"Alright… I'll tell you the whole truth. But please, you HAVE to believe me. It will sound absolutely insane, but just… trust me please."

The young hero was practically begging them to keep an open mind.

Both adults looked at each other with concern. They thought that if this teenager was so scared to reveal what actually happened, then it couldn't be anything good.

They looked back at Ben, and the detective spoke with confidence: -"Whatever it is Ben, I can assure you that we can handle it."

The teen hero however, wasn't filled with confidence. He knew that he was about to tell those two, was going to either rock their worlds or brand him an insane person. There wasn't much of a choice in the matter however, so Ben took a deep breath and spoke…

-"Have the two of you ever heard about the multiverse theory?"


END.


AND SCENE! I really liked writing this chapter, and next one is going to be mind blowing for our new characters. You may be wondering why I'm only using classic aliens for the moment, but it's only temporary, I just thought they would fit these situations more, but don't worry, I'll be using ALL of Ben's transformations in due time.

You guys have NO idea of what I have in store for this story... alongside others as well.

You can also go to my DeviantArt page for some fanarts I made AND go to the fandom wiki of this story, that I will be updating each chapter posted!
