No POV

Long ago, there existed a brilliant young scientist. By dint of his astonishing genius, he was able to make a number of contributions to human knowledge. Eventually, however, he became disillusioned with the world. Though constantly showered with praise for the subtlety of his mind, none of his ideas or theories ever received even the slightest support from the scientific community. We should not be striving to advance human civilization, but rather the artificial evolution of humans as a species. That was the only dream he had ever had, but not a single person came forward to help him fulfill that dream.

Doctor Genus: Damn these simple apes! "Dangerous ideas?" Treating me like a freak? Do these lowbrow simians really think humans have come this far by avoiding risks? Idiots who think that mankind no longer has the need to evolve have no right to call themselves scientists, let alone pass on their genes! Of course, this plan in fruition was always for my own sake. I will carry it out...even if I must do it all myself!

Thereafter, he devoted himself to research. It was only after he turned 70 that his efforts began to yield results that he's been searching for.

(Ring)

Dr. Genus: (Gasp in excitement)

He now has all the date and research he needed to achieve his goal, but first thing he did after completing his research, the scientist regained his youth. Next, he began cloning himself. He named his laboratory, the "House of Evolution," and together with his clones he conducted countless experiments with animals to create new species. Eventually, his experiments shifted to human subjects--

Saitama: This is taking too long!

Armored Gorilla: ...Huh?

Saitama: What's this got to do with me and Y/n? You're just trying to act cool again.

Y/n: You know, to be honest, I really enjoyed listening in to who this Dr. Genus really is, but just get to the point, okay?

Genos: My master is a busy man. Summarize it in 20 words or less.

Leo Gorefield: And you better tell the truth, or else you'll end up like your friends.

Armored Gorilla: Ugh...sure...sorry about that...

After the encounter with the super animals from the House of Evolution, our heroes started interrogating Armored Gorilla to know who's behind all of this and why this Dr. Genus is so interested in both Y/n and Saitama

Armored Gorilla: So, in other words, my boss has become very curious about you two and your bodies.

Saitama: Too bad. I'm not interested in dudes.

Y/n: That is not what he actually meant, Saitama.

Genos: He's right, Master. Your bodies surpass normal human limitations, so he plans to be using them for his research on evolution. If we don't do something, I'm sure he'll try again. We cannot allow him a free hand. Our move should be to attack him.

Saitama: Sure, let's go.

Y/n: Way ahead of ya, Saitama. Let's get going! Times's a-wasting!

Genos: Right! (Realizes what they meant) Huh? Now?!

Y/n: Yeah now! I have plans tomorrow and we have to stop them right away.

Saitama: Yeah, there's a sale on tomorrow. Can't do it then.

Genos: But...Master!

Then as our heroes make their way to the House of Evolution to stop Dr. Genus before tomorrow for the big sale, Armored Gorilla knew that this is not a good sign and needs to warn Dr. Genus that they're headed over to the House of Evolution.

Armored Gorilla: (Thinking) This doesn't sound good. Better tell the Doctor....

Leo Gorefield: Hey, you.

Armored Gorilla: (Shocked) Oh. Yes?

Leo Gorefield: I have one question to ask you in favor of Genos, the Demon Cyborg, regarding the House of Evolution cyborg development. Was the "House of Evolution" developing cyborgs prior to four years ago? How many more cyborgs are there? Have any of them destroyed towns in the past?

Armored Gorilla: I'm not really sure, but at the "House of Evolution," I'm the only combat cyborg.

Leo Gorefield: I see.

Armored Gorilla: You know, despite of barging in to kidnap your friend, I was wondering how he is able to become that strong?

Leo Gorefield: Are you? Well, since you're trapped here until the authorities arrive, do you want me to explain my brother's origin story? It is quite a long and fascinating story.

Armored Gorilla: Yeah, sure. I got nothing else to do and I'm stuck here, so why not.

Leo Gorefield: Very well then.

Then as our heroes head their way to the House of Evolution while Leo is keeping an eye on the place as he explains Y/n's origin story to Armored Gorilla, we cut over to the House of Evolution as Dr. Genus couldn't believe that his team that he sent to capture Y/n and Saitama were all wiped out except for Armored Gorilla that is being watched over by one of the Zodiac Gorefields.

Dr. Genus: Impossible! Our elite force, formed for the extermination of these obsolete humans, wiped out?!

Dr. Genus Clone #1: According to Armored Gorilla's report, the three responsible are on their way here.

Dr. Genus Clone #2: If they come, all our research, everything we've been working on, could be destroyed.

Dr. Genus Clone #3: This is a serious matter.

Dr. Genus knew that this will be the end of his whole career once our heroes arrive to ruin it all, but he has one last option that he had no other choice, but to use it as a last resort that might be powerful enough to stop them.

Dr. Genus: The only option is to use our trump card. Begin preparations for the release of Carnage Kabuto.

Dr. Genus Clones: What?! - No, not him! - That's crazy! - He'll finally be released? - He's right. That might be the only way. - But maybe we should stop him. - It's too dangerous. - I have a bad feeling about this. - Is that the only way?

Dr. Genus: Quiet Down! He will be our last resort.

Dr. Genus Clone #4: (Scared) But sir...

Dr. Genus: First, from the first to the eighth floor, we'll activate all our traps. If we're lucky, they will take care of the intruders. I'm fully aware of what will happen to me should we fail.

Then we cut back to the heroes who are currently speeding their way over to where the House of Evolution is located as they are running incredibly fast in order to speed things up to get this job done and over with so that Y/n and Saitama will be on time for the big sale going on Saturday.

Genos: I didn't think we'd be running the whole way.

Saitama: How else are we gonna get there?

Y/n: I agree. This might be our first and quick mission to stop the villain that's behind this "House of Evolution" business. I'm actually pretty excited for what we're up against.

Genos: It was my assumption that you both have the ability to fly.

Saitama: You know, Humans can't fly, right?

Y/n: I can actually fly. Normal humans can't fly unless they've been gifted with wings or the power to fly.

Genos: It's amazing that you two are never late. You both are true heroes.

Y/n: I appreciate the compliment, Genos.

Saitama: Really? You're kidding, right? I hardly ever arrive on time.

Then after a quick trip on foot, our heroes have finally arrived at House of Evolution, thanks to the information from Armored Evolution and with plenty time to spare to get the job done as quick as possible.

Y/n: We're here. This is the place we were told about.

Saitama: So, this is...

Y/n: The "House of Evolution." But we better be careful though, I can sense various traps within this building.

Saitama: (Counting the floors on the building) One, two, three, four, five, six...Looks like it's about eight stories high--

Then without warning, Genos used his Incineration Cannons to blast the entire building to smithereens.

Saitama: Uh...what was that all of a sudden?

Y/n: Yeah, that seems a bit rash, isn't it?

Genos: Yes. I decided it would be most efficient to destroy them all in one swoop.

Saitama: Well, that's true but...We could have at least seen what the bad guys had in store for us. That was kind of mean.

Y/n: I hate to say it, but I have to agree with Saitama there. (Notices something that was under the building) Looks like there's a basement. What a smart way to have the House of Evolution located underground to avoid getting detected by the authorities. A smart way to have a secret base located as long as you're careful on where to have this hidden lair located. Let's go in and see what we're dealing.

Saitama: Way ahead of ya.

Then Saitama grabbed the trapdoor and peeled it away like an orange as our heroes went down to find the villain as we cut over to one of the rooms, where they kept this monster named "Carnage Kabuto locked up and for a good reason as he is known as the strongest creature in the House of Evolution and the most dangerous, which is why Dr. Genus had him locked up since he is an unstable and bloodthirsty monster as one of Dr. Genus's clone started firing an assault rifle that is not dealing any damage to the creature that is about to kill him in cold blood.

Dr. Genus Clone: S-Stop it!! Just stay away!!!!

POW!!!!

With one punch, the clone was done for as the whole room, where Carnage Kabuto is imprisoned in full of fresh blood as he managed to kill a bunch of Genus clones as it wasn't enough to satisfy him and his unquenchable bloodlust. Then Dr. Genus entered the room and approached the creature, while being extremely careful on talking to Carnage Kabuto to ask him to take on Y/n and Saitama for his research on evolution.

Dr. Genus: Hey, Carnage Kabuto. Tell me if you're feeling alright? It would appear that you've killed a bunch of my clones again. Are you satisfied?

Carnage Kabuto: Huh? You Fool! Why would I be satisfied, huh? I've been kept locked up deep beneath the Earth. I'm the strongest warrior in the entire "House of Evolution!!!"

Dr. Genus: You're imprisoned here because you are mentally unstable. We couldn't control you. There was no choice in the matter.

Carnage Kabuto: Control? (Laughs) Moron! I am the culmination of the "New Human" you guys have sought for so long. My intelligence and physical strength and your own are incomparable! The way I see it, you and all of your clones should be the ones obeying me! (Sticks out his tongue at Genus)

Dr. Genus: (Thinking) No. You're a failure. It's true you perform at unheard of levels, but you lack humanity. (Speaking) Go ahead, kill me if you want. Plenty of clones could take my place.

Carnage Kabuto: Oh?

Dr. Genus: But I have a favor to ask first. There's a couple of specimens that I simply must have.

Then Dr. Genus showed Carnage Kabuto the video of Y/n, Saitama, Genos entering the building as Genus explained about Y/n and Saitama are both known to be very strong, except Y/n has a bunch of other powers and abilities that Saitama doesn't possess as he asks Carnage Kabuto to fight against Y/n and Saitama in a battle.

Dr. Genus: They're proven to be extremely strong. Only you can defeat them. However, the boy in the white and yellow hoodie jacket has a lot more powers and abilities that are proven to be unpredictable, so I suggest you be careful about what you're up against.

This has caught Carnage Kabuto's interest as he gladly accepts Genus's offer to fight Y/n and Saitama in a battle to the finish.

Dr. Genus: I want you to catch them for me...dead or alive.

-Back to Y/n, Saitama and Genos-

As we cut back to our heroes, they're currently walking down the very long hallway as the whole basement is so big, it's like they're walking for miles.

Saitama: This basement is huge! I'm getting kind of fired up.

Y/n: Same here. This scientist seems to be very rich to build a basement this huge to create such interesting experiments. I wonder what he has in store for us, now that we entered his turf.

Then they stopped after Genos detected something coming at them at high speed.

Saitama: Huh?

Y/n: What's wrong, Genos?

Genos: I sense living beings deeper in, Y/n, Master, two of them are approaching.

Y/n: (Detected something with his mind) I can sense it too and it's a big one!

Then they look straight down the hallway to see who they're up against as Carnage Kabuto charged down the hall, destroying the lights shining down the long hallway, while carrying Dr. Genus in one hand.

Carnage Kabuto: Oh, here we go! There are three. Which one is it?

Dr. Genus: The ones on the right...

Carnage Kabuto: In that case, you don't need the one on the left!

Then with one swift strike of the wrist, he slammed Genos's face to the wall, knocking him out as Y/n was shocked to see that with his own two eyes as he saw the monster that attacked Genos as he appeared behind him and Saitama as he introduced himself to them before challenging them both to a fight in the House of Evolution's combat room.

Carnage Kabuto: My name is Carnage Kabuto! We got a combat experimentation room down this way! Let's throw down in there!

Saitama: You turned Genos into a piece of bad modern art.

Y/n: And since you're willing to fight against us in another room, then you got yourself a couple of worthy opponents.

Y/n/Saitama: Let's do this!

Then Y/n and Saitama were both led into another room, which incredibly has a ton of space that is big enough for the entire population of an entire city area or the entire country. As Carnage Kabuto is all pumped up and ready to fight the two heroes to the death in the Combat Room.

Carnage Kabuto: Pretty big, eh? It's the largest room in the facility. This is where they make us fight to test our combat abilities, which there's pretty enough room to kick both of your asses. Well then, let's start the killing--

Then suddenly, just before they're about to fight, Genos fired his Incineration Cannon at Carnage Kabuto, which didn't even affect him whatsoever.

Carnage Kabuto: Oh? Still alive, huh?

Then Genos took a deep breath before dashing his way over to him at amazing speeds to unleash his attacks on Carnage Kaubto, which didn't harm him at all, before performing a very high jump over to him to unleash one of his more deadly attacks on Carnage Kabuto.

Carnage Kabuto: You fool!

Genos: Machinegun Blows!

Then he started punching at Carnage Kabuto like a machine gun, only to be punched by Carnage Kabuto as the Machinegun Blows attack move didn't work on the monster either as he is definitely a very strong monster in the House of Evolution as Genos was soon caught by both Y/n and Saitama as his face is cracking up and his body is getting smashed into pieces by Carnage Kabuto's impressive inhuman strength.

However, Genos refused to give up as he tries his best to stay up and fight against the monster.

Genos: He got me good....Let me...take him...

Saitama: Your face is cracked, and you're all smashed up. Don't push yourself.

Y/n: He's right, Genos. You're not strong enough to stop him. Take a breather or you're gonna die.

Then Genos fired his Incarnation Cannon at full blast at Carnage Kabuto, only for him to blow it back at him as that attack is proven useless against him that greatly surprised Y/n that a monster that powerful could blow it back at Genos as he used his powers to create a shield barrier to protect him, Genos and Saitama from the flames until it died down.

Genos: With his breath? Impossible!

Saitama: (Shocked) Genos, you, okay?

Genos: Yes...

Then after the flames died down, Genos' hair became an afro after that flame attack backfired on them.

Saitama: No, you're not! Look at your head!

Then Y/n decided that enough is enough as he plans to fight against Carnage Kabuto by himself.

Y/n: Saitama. Watch over Genos. I'll deal with this bozo.

Saitama: What? Are you sure about that? We can both take him on, and we can make the job go by faster.

Y/n: I understand, but there are more important matters to deal with than to be on time for the sales. You can leave this place with Genos if you two want to survive. That way, you'll get to the sales on time without me.

Then Y/n soon got into a fighting stance and is ready to take on Carnage Kabuto, not noticing that Dr. Genus is slowly limping towards the Combat Room to see the action of Y/n, the Son of Godfield as he is about to fight against the strongest monster in the House of Evolution.

Then as Dr. Genos began explaining more about himself, we soon see flashbacks of his past life at the age of 15 that fully explains why he is determined to create a whole new world filled with so many ideas of creating a perfect utopia in his own image.

Dr. Genus: (Thinking) I have always been critical of humans and their inferior abilities. The entire species, aside from myself, can be viewed only as dumb animals. That realization was agony for me. If memory serves, I was 15 when it occurred to me. A plan to evolve the human animal and create a world where I could live contentedly. A utopia of my own, created by me. A world made up of only us, the new human breed that will transcend humanity! Bring about a new world order!

Then as he finally made his way to the Combat Room, he fell down for a moment to regain his stamina due to the amount of pain he's in from Carnage Kabuto, but he doesn't seem to care about his current condition and all of the pain he's in right now as he willing to do whatever it takes to see what Y/n is capable of when he goes up against Carnage Kabuto in battle.

Dr. Genus: (Thinking) I must see it through. Compared to my anguish back then, this physical pain I feel now is nothing.

Carnage Kabuto: What's the hold up? Let's get this thing going! Bring everything you've got.

Dr. Genus: (Thinking) Carnage Kabuto--the strongest and most brutal creation of the House of Evolution. Let's see how you, at your god-like state of human development as well as this mysterious feline from another world, fare against a monster that is the apex of artificial evolution. Or will you be the trigger for a new evolution of your god-like capabilities that will show new forms of evolution and species from what the multiverse has to offer? I can't wait to find out!

Then Y/n took a step forward towards Carnage Kabuto with a serious look on his face as he is ready to take on this monster.

Carnage Kabuto: Oh, I see it. I see it! You're supposed to be strong.

Y/n: Don't disappoint me now. You're this place's ultimate weapon, right? You're clearly not the same as the guys from this morning. I mean, look at you, just oozing with confidence. If you think you're so tough, then...Show me what you got.

Then without warning, Carnage Kabuto ran across the room at the speed of light, shocking Genos to see how fast he really is.

Genos: Such speed!

Then he appeared behind Y/n and is about to punch him, only to stop for a moment after he felt something that nearly got him a heart attack as he immediately flew back to the closest wall, far away from Y/n as he nearly got killed by Y/n just for trying to attack him from behind before sensing a very powerful force inside Y/n that got him so worked up. Saitama was confused to why he ran away like that.

Saitama: What are you doing? Hey!

Carnage Kabuto was too scared to even say anything or make fun of him as his heart was beating heart from the near-death experience he just had when he tried attacking Y/n from behind as Y/n slowly turned around to look at Carnage Kabuto with his eyes glowing brightly in a menacing tone and the monster can suddenly see something behind Y/n that appeared to be some sort of cat-like deity that looked down at Carnage Kabuto with the same look as Y/n as a million questions began rolling in his brain with Dr. Genus completely and utterly shocked to actually see Carnage Kabuto retreat from a battle for the very first time.

Dr. Genus: Absurd!! Carnage Kabuto retreating?!

Carnage Kabuto: (Thinking) If I'd attacked him just now, he'd would have killed me. Who the hell is this kid? He's leaving himself wide open, yet all my instincts are screaming, sending out danger signals!

Then with a burst of anger, Carnage Kabuto let out a loud scream as he never met someone that is just as dangerous as him that made him cower in fear.

Carnage Kabuto: BASTAAAAAAAAAAAAARD!!!! What are you some kind of freak?! How the hell did you get that strong?!

Then Y/n didn't say anything for a moment before decided to tell him and the others in this room about his origin story as there is no one else around that will learn about his secret.

Y/n: You wanna know how I got this strong? Very well. (To Genos and Saitama) Genos. Saitama, you two better listen carefully too, cause this story is very important and is way more than 20 words or less.

Saitama: (Thinking) Is he going to tell us?

Genos: (Thinking) He's going to tell us right now?

Saitama/Genos: (Thinking) The secret to Y/n's amazing power?!

Doctor Genus: I'd like to know as well.

Y/n: (Turns to Dr. Genus) Huh? Who are you?

Dr. Genus: I am Genus.

Y/n: (Sighs) Very well then. Listen up, this story will be a once in a lifetime opportunity to know about my origin story.

Genos: (Thinking) It's too risky! He must let these guys know his secret!

Saitama: (Thinking) I'm aware of what will happen if he reveals about his secret of how he became this strong, but I'm willing to listen to every word he said, even if it's more than 20 words or less to understand him.

Y/n: The thing is, I'm not always like this, in fact, I'm not from this world.

(Story Explanation:)

Where I came from, I lived in a world filled with nothing but sin and corruption. I wasn't always like this, but that all changed when I met a stray cat by the name of Garf and we became best buds since that night as we both did our best to survive the harsh reality, we're both in. Until one faithful night, Garf began to evolve into a much more powerful creature, and I showed no signs of fear of his newfound abilities.

Unfortunately...

That's when tragedy struck upon us both as 2 hunters came by to kill my only friend and I took the bullet for him as a noble sacrifice to let him live, but eventually he didn't take that one and only chance to escape as he soon suffered the same fate as I have.

While our bodies are lying on the ground to rot while the hunters smiled and laughed in victory without a care in the world for human or any life whatsoever, the Earth shallowed us both and Garf began to evolve again, and he absorbed my dead body into him to fuse together to become as one.

Our bond was so strong and pure, Garf was willing to do whatever it takes to bring me back to life, but as time went on, curiosity got the better of him as used his 'eyes' to discover what the Earth has in store for him as his eyes were shattered all across the entire planet as he was shocked to see all the chaos and destruction that these humans have caused to damage Mother Earth's life force to oblivion.

Then he took the time to look upon the place I once called 'home' that is nothing but a prison to me and he was shocked to see that my own parents along with the rest of my family were all cheering for my own death as Garf was now shocked and disgusted by the sight of my own family as he is filled with hatred and anger.

So, with enough energy, he became a lot more powerful as his new form was capable of destroying plants with a single energy blast as he recreated the entire universe in his own image with the ashes of the old world, thus becoming a perfect world where there is no such thing as sin or corruption as me and Garf became as one and as a God known as...

Godfield.

Over 1000 years, he trained me under his wings as his own son and after my training is complete, I have become strong as my own father....

But it gave me no satisfaction...in succeeding...

We both lost all purpose; despite all the things we've done to our world to make it a perfect utopia....

Y/n: That is when we decided to travel across the many worlds across the cosmos to find a real challenge, see what the multiverse has in store for us, which lead to us here at this point of time to know about this 'House of Evolution' and I must say, Dr. Genus. You're attempts of creating this type of evolutions and species is quite impressive and not only that, but you also managed to cheat death twice by regaining your younger age while creating an army of your own clones in case you die in any type of certain death for one of your clones can take your place. Not to mention that your most powerful and brutal creation seems like a real challenge, if he didn't back away when he is about to attack me from behind that is.

Dr. Genus: (Thinking) I have to admit, I'm flattered that you find me and my House of Evolution, interesting, but after hearing about your backstory and how you became this strong...I completely understand everything about you. But I now know that it might be too dangerous to use you and your father for my experiments. They might be just as dangerous as Carnage Kabuto, but with a little more work and brainpower, we could actually make this work for the both of us.

Carnage Kabuto: (Thinking) Is this guy for real?

Saitama: (Thinking) Godfield, huh? He's a lot like me. (Speaking to Y/n) You know what? After listening to every word you said, I now fully understand why you came here in the first place.

Y/n: And what would that be?

Saitama: Because.....that kind of power you possess is what make you awesome!

Y/n: Ok....

Saitama: Well, since you told us everything about you, I guess I should tell how I became a hero and how I got this strong.

Y/n: Are you sure you want to do that, Saitama?

Saitama: Well, you wanted to find someone to fight that is strong as you and I thought maybe I would tell you how I defeated that giant mosquito from before.

Y/n then remembered seeing Saitama slapped Mosquito Girl with such raw power that immediately changed his mind as he allowed Saitama to explain about how he became the strong here he is today.

Y/n: Fine. But since you agreed to explain your backstory, then your secret with be safe with me.

Saitama: Alright. First, what's important is, to make sure you stick to this intense training regimen.

Y/n: (Thinking) Training? Is that it?

Godfield: (Thinking) It's possible but seeing how his limiter was shattered by just training has piqued my interest.

Dr. Genus: Wait a minute? Not modification surgery or genetic enhancement, just training?

Carnage Kabuto: What training...?

Saitama: Listen, Genos. You just have to keep doing it. No matter how hard it gets. It took me three years to get this strong. One hundred push-ups! One hundred sit-ups! One hundred squats! Then a ten-kilometer run. Do it every single day!

(Story Explanation:)

As Saitama explained about his backstory, we see a young Saitama with hair running down the path to become a strong hero as the caped baldy continued explaining his backstory to everyone in the room about how he became strong today.

Saitama: And of course, make sure you eat three meals a day. Just a banana in the morning is fine. But the most important thing is to never use the A/C or heat in the summer or winter so that you can strengthen the mind.

Saitama: In the beginning, you'll wish you were dead. You might start thinking what's the harm of taking a day off? But for me, in order to be a strong hero, no matter how tough it was, even if I was spitting blood, I never stopped.

Then we see Saitama doing his training regimen, despite of how tired or how much pain he's in right now as he kept pushing himself to the limit no matter how tired he is or how much pain he's in right now.

Saitama: I kept doing squats even when my legs were so heavy they refused to move. Even when my arms started making weird clicking noises, I kept doing push-ups.

Then after a year and a half, Saitama soon noticed a difference after looking at the mirror to see all of his hair fallen out and became bald, thus breaking his own limiter and has become stronger than ever before.

Saitama: A year and a half later, I started to notice a difference. I was bald...and I had become stronger!

The result of breaking his own limiter shows how he managed to destroy a monster with just one punch. Then we cut back to Young Saitama running his 10k run until the Present Day Saitama ran past his younger self at lightning speed.

Saitama: In other words, you gotta train like hell to the point where your hair falls out. That's the only way to become truly strong. The guys that are fooling around with the "new human race" and evolution junk will never make it this far. Human beings are strong because we have the ability to change ourselves.

Dr. Genus: (Thinking) W-What did he say?

Y/n: (Thinking) Is he really serious about that?

Godfield: I'm pretty sure he's telling the truth and after hearing his own backstory, I do believe that his story is 100% true and I believed every word he said about him.

Genos: Master...You are so...(Shouting) FULL OF CRAP!

Y/n/Saitama: Huh?

After Saitama explained his backstory to everyone, Genos doesn't seem to believe Saitama's backstory about how he became a strong hero as both Y/n and Godfield were shocked to hear the Demon Cyborg saying that Saitama's backstory is full of lies as he demands Saitama about his true secret of his amazing power.

Genos: That is nothing but standard strength training! And it's not even that intense! It's just a normal level! I...I have to get stronger. I didn't ask to study under you just to hear jokes! Master Saitama, your power is clearly stronger than
what you'd get from just training your body.

Dr. Genus: That's right, we want to know your--

Genos: Your true secret! Please reveal it!

Y/n: Look, Genos...I understand that you want to get stronger to avenge your family from the cyborg you're hunting down, but you may not believe him, but that's really all he did.

Then Genos soon realized what Y/n meant, until...

Carnage Kabuto: Oh yeah?

Carnage Kabuto had enough of this nonsense as his anger went up to the MAX as his body began to change, shocking Dr. Genus as he seen this happened before.

Doctor Genus: No! Carnage Kabuto! Don't do it! You mustn't!

Carnage Kabuto: If you two don't wanna tell us your secrets...so be it!

Y/n: (To Dr. Genus) Doc! What's going on with him?

Doctor Genus: He's changing into his final form, he's about to go on another rampage!

Y/n: WHAT?!

Then the alarm went off as the door that is their only exit is the shutting down, blocking everyone in the room to prevent them from escaping from what's about to happen from Carnage Kabuto.

Carnage Kabuto: I bet you two aren't stronger than me! NOT EVEN CLOSE! But, since you both seriously pissed me off, I'm gonna annihilate you.

With a sudden burst of adrenaline and rage, Carnage Kabuto changed into his final form...

CARNAGE MODE!

With his transformation complete, the whole room changed to a black and red lighting making the floor look like they're standing in midair as Carnage Kabuto explained about his Carnage Mode form before he unleashed his anger

Carnage Kabuto: When I get like this, I lose control for a whole week and my lust for death cannot be quelled! After I kill you both, I'll head into town and go on a killing rampage until next Saturday!

That suddenly caused Y/n (Including Godfield) to go into a great shock after he mentioned about going on a killing rampage until "next Saturday" as Carnage Kabuto is planning to kill anyone in his path without conscious or mercy, making a whole entire week feel like a "Monday of No Return".

Carnage Kabuto: If you two are indeed a couple of strong heroes, then try and stop me!

He then let a roar of anger before he is about to land a punch on Saitama, Y/n quickly teleported in front of Saitama and took the bullet for him as he is taking whatever Carnage Kabuto throws at him, shocking Saitama, Genos and even Dr. Genus of what they're seeing right now.

Saitama: (Thinking) No way...it can't be. I may have made a horrible mistake. This guy is in Carnage mode...He said he'll be on a rampage for a whole week?

Then Carnage Kabuto started punching at Y/n multiple times in a fury of punches screaming the word, "Die" so many times as he repeatedly kept punching Y/n to a bloody pulp, despite of Y/n, not taking any sort of damage with him with his arms blocking his attacks.

Saitama: He said that will be like this till next Saturday. One whole week from today...Next Saturday...In other words, today is Saturday too. That means...Today is... (Realizes something) Now I get it. Y/n took the bullet for me, allowing me and Genos to escape in order for me to get to the sales on time before it ends....

Y/n: (Flashback) I understand, but there are more important matters to deal with than to be on time for the sales. You can leave this place with Genos if you two want to survive. That way, you'll get to the sales on time without me.

Dr. Genus: (Thinking) It's all over. There's no one in this world that can stop my glorious creation...though I can't help but feel sorry for this man that suffered the harsh realities in his own universe and how he sacrificed his own existence to become a God.

Then without warning, Godfield finally decided to come out and teach that monster a lesson as Y/n quickly switched places with Godfield as he punched Carnage Kabuto to a bloody pulp with all of what's left of him turned into green goop from that punch and Godfield towered over Saitama, Genos and Dr. Genus in his giant form, shocking the three of them of what just happened after they all got to see what Godfield truly looks like.

Dr. Genus had never seen such a majestic creature like Godfield as the godly feline roared in anger when he prevented Carnage Kabuto from going on a bloody killing rampage for a whole week, killing hundreds of innocent people and heroes in his path if he didn't stop him in time before the sales could even happen.

Dr. Genus: Who the hell is this guy?! Why does he sound angry right now?!

Genos: I'm pretty sure he's upset about this.

Then Genos showed Dr. Genus showed the papers of the sales that read SATURDAY ONLY!!! GIGANTIC SALE!!!

Then Saitama thought about something that could work out.

Saitama: Hey! Wait a minute!

Then Godfield stopped what he's doing and looked down at Saitama as he got an idea that could get them to the sales on time before the store closes.

Saitama: I got an idea. You can create portals to other worlds, right?

Godfield: Yes? Why do you ask?

Saitama: What if you create a portal the supermarket, that way we can get to the sales on time.

Genos: That's right, the store closes at 10 PM tonight and getting to the store on foot is about four hours away from here. If you can create a portal to the supermarket, we can make there on time.

Godfield then realizes that he can actually do that and smiled at them as he quickly changed back to Y/n as he immediately created a portal to the supermarket to grab those sales before the store closes.

Y/n: Then what are we waiting for! Let's get going before the sale is over!

Saitama: Right! Let's go, Genos!

Genos: Yes, Master!

Y/n: (To Dr. Genus) Thanks for your time, Doc! I hope we'll meet again soon!

Dr. Genus then watched the three of them went into the portal after witnessing Godfield in person as he decided to move on from continuing his research on evolution as if meeting Godfield and his own son, Y/n has inspired Dr. Genus to start his life over, but he will keep the secret about Y/n and Godfield along with all of his research to himself as he soon realized that he is the one that must change for the better.

He will never forget this moment in his entire life.

Dr. Genus: I think I'm done with evolution....It would appear...I am the one who must change. Y/n....Godfield...now that I know who you are and what you're capable of....I will keep this secret of yours to myself...as well as my research on evolution...I won't forget this moment as long as I live.

A Few Days Later...

After all of that trouble at the House of Evolution, a group of workers from the Hero Association are investigating at what's left of the House of Evolution as they are all gathering evidence to locate the hero known as Genos aka the Demon Cyborg that caused all of this damage to the House of Evolution. Right now, a Hero Association Worker was talking to the others at the Hero Association on the phone.

Hero Association Worker #1: Yes. The on-site investigation is underway. Yes, that's correct. Just like the other cases, the area has been thoroughly burnt by intense flames. Everything points to the young cyborg being responsible for this. Yes, understood. (Ends call and talks to the other worker) Such a devastating amount of power.

Hero Association Worker #2: Yeah...

Worker: Sir. We uncovered something else from the ashes.

Then the worker showed a glowing white and yellow angel feather that belonged to someone that got the Hero Association worker's interests on another investigation subject that they've been working on after witnessing what happened during the monster attacks along with the restoration of City B.
