A-City

Flying towards the large monster that was stomping through the city was Ben in his Jetray form. He had only just came to this world and he was already going to fight a monster to save it. Ben managed to fly next to the large monster and surprisingly there was a man in a lab coat riding on the shoulder of the monster.

"Go my brother, march forwards and destroy this city, once we are done here, we will rule the entire planet" the man in the lab coat said with an evil laugh

"I don't think you should do that" a voice said

The man in the lab coat looked over and saw a bald headed man wearing a yellow suit and a red cape, standing on the monster's other shoulder

"What in the, how did you get up here?" The man in the lab coat asked surprised

"Why don't you both get down and let me stop this monster" Ben said

Both the balled headed guy in the superhero costume and the man in the lab coat looked up and saw Ben hovering in the air

"Another monster?" The man in the lab coat asked

"Hey look, that one flies" the guy with the balled head said

"Definitely not a monster" Ben said

"Go away whatever you are, can't you see my brother and I were here first" the man in the lab coat said

"I'm afraid I can't do that, I'm a hero and I'm not going to let you destroy the city with your brother or whatever that thing is" Ben replied

"I'm also a hero" the balled headed guy said speaking up

"I do not care what either of you are or aren't, both of you will die, brother kill the one on your shoulder then kill the flying creature" the man in the lab coat said angered

The giant monster raised its massive arm into the air then slammed it down on the man in lab coat, to the surprise of Ben and the balled headed guy

"Well that happened" Ben said

"Was not expecting that" the balled headed guy said

At that moment the giant monster realized what it had done, it realized that it killed its brother instead of the balled headed guy on his shoulder. That put the monster into a rage, causing him to destroy the buildings around him. Ben began to fire neuroshock beams from his eyes and tail at the monster, getting its attention.

"DESTROY YOU!!!" The monster roared as it tried to smash Ben

"Don't forget about me" the balled headed guy said

The monster grabbed the balled headed guy and threw him into the roof of a building. Ben went to go and help the guy, to make sure he was ok but he was grabbed by the monster.

"You better let me go" Ben said

The monster didn't listen and began to crush Ben with its massive hand

"This…definitely doesn't…feel…good" Ben said as he was slowly crushed to death

Before Ben could get crushed to death, Ben fired his neuroshock beams into the eyes. That attack caused the monster to let Ben go, letting him get free and able to move away from the monster. The balled headed guy pulled himself up from the rubble as Ben landed down next to him.

"You okay?" Ben asked the guy

"I'm okay, what about you?" The balled headed guy answered, asking Ben if he was okay

"Same here" Ben answered

The giant monster stopped wiping its eyes from the damage Ben's neuroshock beams did. It then let out a loud roar as it turned and faced Ben and the balled headed guy.

"Do you have a plan or something monster guy?" The balled headed guy asked Ben

"I honestly didn't think it would take this long" Ben answered

"I'll take that as a no then" the balled headed guy said

"I think I've got something that might just work" Ben said

Ben then took to the air and began to fire his neuroshock beams from his eyes and tail. He did this as he flew closer and closer to the giant monster, the beams hurt the monster burning its skin. The monster raised its arm into the air and slammed its fist down on Ben. It appeared as though the monster had killed Ben by slamming him down into the roof next to the balled headed guy.

"Huh, that didn't work" the balled headed guy said

Just then, something began to slowly lift up the fist off the giant monster, the balled headed guy didn't know what it was. As the fist got fully lifted up, it was revealed that a being who's body was made of a purple rock was lifting up the monster's fist. The being had magenta crystals sticking out of its body, it had a long crystal sticking out of its head like a horn. The being also had one eye, no nose and a mouth, the omnitrix badge was located in the center of its chest. This was Chromastone, Ben's Crystalsapien transformation.

"What happened to that flying monster guy?" The balled headed asked

"I'm that same guy" Ben said as he struggled to fully lift the monster's fist up

"What?'" The balled headed guy

"Never mind, I'll explain later but for now could you do something, I don't know how long I can keep this up" Ben said

"Ok" the balled headed guy said

In an instant the balled headed guy jumped into the air with ease and went to punch the giant monster. At the exact moment the balled headed guy's fist met with the monster's face, it exploded. The giant monster died instantly and fell down into B-City, destroying it in the process. Ben could not believe what he had just seen, some with that incredible strength had never existed in his universe. Maybe Alien X but Ben never used the Celestialsapien transformation as a bruiser.

Who or what was this guy? Ben didn't know but he was glad that the guy was a hero and not a villain. After the monster fell over dead, the balled headed guy landed down next to Ben.

"You defeated it in one punch" Ben said

"Shame, I was hoping it would be more a challenge" the balled headed guy said

"Whatever, that was incredible, how did you do it?" Ben asked the balled headed guy

"I don't know, I just guess I'm strong" the balled headed guy answered nonchalantly

Ben still couldn't believe this guy, his strength was amazing as was his durability. Thinking about it now, Ben wondered if this guy was actually a monster in disguise.

"So do you want to fight next?" The balled headed guy asked Ben

"Wait, what? No, I do not want to fight you" Ben answered in a panic, not wanting to meet the same fate as that giant monster

"Darn, you look strong transforming monster guy, I really wanted to test my strength against you" the balled headed guy said

"Look, like I said before, I'm not a monster" Ben said

"If you aren't a monster, are you a mutant or something?" The balled headed guy asked Ben

"I'm not a mutant either, I'm actually an alien well not really an alien all the time" Ben answered trying to explain to the balled headed guy

To the not so surprise of Ben, the balled headed guy gave Ben a real confused look

"Okay, I'm actually a human who transforms into aliens with this thing called the omnitrix, my name is Ben, Ben Tennyson" Ben explained as he hit the omnitrix badge and transformed back to normal

"Oh" the balled headed guy said

"But wait, aliens don't exist" he added

Ben let out a sigh when the balled headed guy said

"Aliens exist in my universe" Ben said

That made the balled headed guy even more confused then he already was

"I think you might need to go and see a doctor monster guy" the balled headed guy said

"Sure thing" Ben replied with a sigh

"You look lost, do you need a place to stay?" The balled headed guy asked Ben

"Yeah, I kind of need a place to stay" Ben answered

"That's good, my landlord has an apartment available next to mine, you can talk to him later but you can sleep at my place" the balled headed guy said

"Great, you know I didn't get your name" Ben said

"Oh, my name is Saitama" the balled headed guy said giving Ben his name

"And you can call me Ben" Ben replied

The two shook hands and grinned

"You know, you are pretty interesting monster guy" Saitama said to Ben

"Again, I transform into aliens, not monsters" Ben said

"Whatever you say" Saitama replied

Z-City

Saitama lived in Z-City, it was on the outskirts of all the other 26 cities, it was completely abandoned and no one but Saitama lived there. Ben quickly noticed that the city was abandoned and looked like a ghost town. While Ben noticed this, Saitama either didn't care that the city was abandoned or simply didn't notice this. Regardless, Saitama was helping Ben out with his current living situation and Ben wasn't going to complain where the guy lived. Not only because he was the only one helping Ben but also, Saitama possessed the ability to defeat his enemies in a single punch.

It was that same ability plus a few Saitama's other superhuman abilities that intrigued Ben. Ben would later ask Saitama if he could use a few of his aliens to run some tests on him. As the two were walking towards the apartment building that Saitama lived in. As the two were walking, Saitama explained to Ben his origin story and even about the way this world worked. Ben then in return explained to Saitama who he was, where he came from and how he ended up in this universe. Of course Saitama didn't fully believe Ben, thinking he was crazy but after seeing Ben's transformations, Saitama kept an open mind.

"So you are telling me you once ended up on a game show where all the girls you've met had to compete to be your girlfriend?" Saitama asked Ben

"Pretty much, honestly it was just insane and I'm glad I don't have to it ever again" Ben answered

"From what you've told me, it seems like you've done a lot as a hero in your universe" Saitama said

"You could say that, apparently in the future, I was called the hero of heroes or so I thought" Ben replied

"You had said something about that, I still think it is ridiculous that they did that to you for saving the day" Saitama said

Ben grew silent being reminded of that day and what he had gone through after it. Ben and Saitama continued to walk down the street until a large figure who looked like a man/car thing. In Ben's mind the thing before them kind of looked like an off brand transformer.

"You there, I saw you defeat that giant monster and now I want to fight you" the car robot monster said pointing at Ben and Saitama

"Sorry but I don't really want to fight you" Saitama said

"What about you?" The car robot monster asked Ben

"Same here" Ben answered

The two then began to walk past the car robot monster and continued on their way. That only angered the car robot monster and made it jump all the way in front of Ben and Saitama, stopping them once more.

"I am Super Custom YO649Z Mk. II, I loved cars so much that I decked out my body with car parts, if neither of you will fight me then I guess I'll just kill you" the car robot monster said giving Ben and Saitama its name and revealing its backstory to them

Ben and Saitama looked over at one another and didn't say a single word, Saitama gave Ben a look which made him let out a sigh

"I guess I'll deal with you" Ben said lifting up the omnitrix and activating it

Ben scrolled through the playlist of the omnitrix and found an alien to transform into. Once he found the one, the faceplate slid back and the core of the omnitrix popped up. He slammed the core down and was engulfed in a green light. The omnitrix began to change and alter Ben's DNA to match that of the alien he selected. Once the light faded away, it was revealed that Ben transformed into a black blob like alien that had green circuitry marks all over its body. The omnitrix badge was located where the face of the alien would be.

This was Ben's Galvanic Mechamorph transformation that he called Upgrade, it was also one of the original 10 aliens that Ben had when he had the first prototype omnitrix

"Ha, that pathetic form won't be able to do anything to me" Super Custom YO649Z Mk. II said with a laugh

"We'll see about that" Ben said

In an instant, Ben lunged at Super Custom YO649Z Mk. II and began to merge with the technology and machines that was all over his body

"What are you doing?" Super Custom YO649Z Mk. II asked in a panic

"Let's just say I'm shutting ya down" Ben answered as he fully merged with Super Custom YO649Z Mk. II's body

Instead of upgrading it, Ben simply locked Super Custom YO649Z Mk. II's body mechanisms up before leaving his body

"Done and done" Ben said as he transformed back to normal

Super Custom YO649Z Mk. II tried to move his body but soon realized that he was unable to do so. He struggled to move any part of his body which angered him.

"What did you do to me?" Super Custom YO649Z Mk. II asked angered

"Simple, when I merged with your body, I shut down all of your body functions except for your lungs and vocal chords which I am beginning to regret" Ben answered

"Meh, let's just get home already" Saitama said as he walked past the defeated Super Custom YO649Z Mk. II

Ben was quick to follow behind him and leave Super Custom YO649Z Mk. II behind him

"Get back over here and face me, I am not finished, this won't stop me, I will kill you!!!" Super Custom YO649Z Mk. II yelled at Ben and Saitama

"Sure you will" Ben said

"I like to see you try" Saitama said

"Get back here you balled headed bastard and you shape-shifting freak!!!" Super Custom YO649Z Mk. II yelled at Saitama and Ben

When Super Custom YO649Z Mk. II yelled that, Saitama stopped walking, he stood still. Ben began to worry about Saitama but when he turned around and had a scary glare on his face, Ben worried more about what was going to happen to Super Custom YO649Z Mk. II. In an instant, Saitama appeared in front of Super Custom YO649Z Mk. II with speed that may even surpassed XLR8, Ben's Kinceleran form. Before Super Custom YO649Z Mk. II could even say anything, Saitama hit him with one of his punches that completely destroyed him, leaving nothing behind.

"Don't call me bald" Saitama said as steam came off of his fist

Saitama then slowly walked over back to Ben who was standing still, frozen and silent

"Hurry up Ben, I'm getting hungry" Saitama said as he walked past Ben

Ben snapped out of his trance and caught back up to Saitama

"Please remind me to never anger you" Ben said

"Sure" Saitama replied

Unknown Location

Laying on the ground next to a burning house we see an injured Ben, he is barely conscious as the heat from the flames get to him. Ben slowly opens his eyes and sees that the house that is on fire is his parent's home. Slowly Ben tries to get up from the ground and run over to his parent's home. The screams of Ben's parents echoed in his ear as he ended up crawling towards the home.

"I'm c…coming" Ben said as he pulled himself forwards on the ground

As Ben continued to crawl, he looked over and saw something that shocked him. It was the bodies of Gwendolyn and Kevin, both looked as though they had been tortured to death. Seeing them laying there like that shocked Ben and scared him. He tried to crawl away from them only to bump into the dead body of Rook.

"What's going on? This can't be happening" Ben said in shock

At that moment, the bodies of both his parents landed next to him, both of them looked as though they were also tortured to death

"Mom…Dad" Ben said in shock

A deep and loud laugh caught the attention of Ben, he looked up and saw a large shadow figure standing in the burning doorway of his house. The figure was holding Ben's grandfather in their grasp.

"Grandpa NO!!!" Ben yelled as he reached out towards his grandfather

"You are going to suffer as I have suffered" the shadow figure said to Ben

"Leave him alone" Ben said as he struggled to get to his feet

"I will take them away from you as you have taken from me, blood for blood, flesh for flesh" the shadow figure said to Ben as they rammed their fist into Max's chest, killing him instantly

"NOOOOO!!!" Ben yelled at the top of his lungs

"You aren't there to protect them, they are vulnerable without you, now they will die by my hands" the shadow figure said as their eyes glowed red

Saitama's Apartment: Z-City

"Ben wake up" Saitama said to a sleeping Ben

Ben kicked in his sleep, not waking up

"I'll punch you" Saitama said

Immediately as Saitama raised his fist, Ben woke up in a panic, looking around at his surroundings

"Where am I?" Ben asked sweating profusely

"Your at my place" Saitama answered confused

Ben continued to look around and saw that he had only had a nightmare, everything he saw wasn't real. Realizing that and seeing that he was indeed in Saitama's apartment Ben calmed down a bit.

"Hey uh Ben, we've got some visitors" Saitama said getting Ben's attention

"Wait, what do you mean we have visitors?" Ben asked confused

"Go outside and look" Saitama said pointing at the window with his thumb

Ben got up and looked out the window, he saw a large group of weird looking people standing outside coming from these holes in the ground

"Okay, um, who are they exactly?" Ben asked Saitama

"Apparently they are called Subterranean People and they have come here to invade the surface" Saitama answered

"I think we should do something about that" Ben said

"Same, I was just waiting for you to get up" Saitama replied

"Well, I'm up now so let's get to work" Ben said

Saitama grinned as he and Ben jumped out of the window to face the Subterranean people and stop them from invading the surface

"You humans, today you will die" one of the Subterranean People said to Ben and Saitama

"We'll take you on" Ben said

"Show us what you've got" Saitama said

Just then an even larger Subterranean Person came up from the ground and looked down on Ben and Saitama. This was the Subterranean King, he had four arms and giant lava swords.

"I, the Subterranean King will fight both of you and once you are defeated my people and I will take over the entire surface world" the Subterranean King said pointing one of his lava swords at Ben and Saitama

"You better transform into one your monsters" Saitama told Ben

"Aliens not monsters but you are right I should transform" Ben said activating the omnitrix

In an instant, Ben transformed into a large dinosaur like alien that had tan skin and wore a green sash and a black speedo. This was Ben's Vaxasaurian transformation that he called Humungousaur.

"A dinosaur, cool" Saitama said looking at Ben fully transformed

"You ain't seen nothing yet" Ben said as he grew in size causing boney plates to emerge from his skin

Once Ben was done growing, he and Saitama charged forwards at the Subterranean King, ready to fight and defeat him

A/N: Hey readers, finally I am able to publish a new chapter for this story. Sorry it took so long for me to get to it but I've had a lot on plate, work, dealing with the virus and all that. I am still going to be updating this story and publishing as many chapters as I can. Heads up, I will be doing both seasons of One Punch Man and a few of my own chapters after I've finished both seasons. I can't go into further detail about that without spoiling a few things I am working on for this story.

As for now, who do you think that figure that Ben saw in his nightmare was and if what he saw may come true? I wanna see all of your guesses and what you think that dream means or represents. Now, thank you for reading and for your support, I will see you all later
