Location: Y/n's Apartment - Abandoned Apartment Complex - City Z

No POV

It's been a few weeks since Y/n and Godfield lived in City Z that is connected to their own universe in their own apartment in the abandoned apartment complex at City Z as they are just minding their own business and are about to water their cactus plant on the balcony.

News Reporter: What could be the cause of the massive mosquito outbreak this year? We ask Mr. Kafetch, a mosquito expert who has written several books on the subject.

Mr. Kafetch: Thank you for having me. Well, let me come right to the point. These mosquitos belong to an entirely new species. Therefore, I know nothing about them.

News Reporter: Oh, come on! What good are you?! Get off of my show! (Clears throat) Now, let's take a look at the areas-

Y/n: Man, City Z's in their path.

News Reporter: - likely to be hit hardest by the outbreak.

Y/n: (Waters his cactus) Now we've got a mosquito outbreak? That's not a good sign.

Godfield (Normal Garfield Form): True and with a massive mosquito outbreak, that means that they're after people's blood.

Y/n: I think we should do something about it before all of the citizen's blood are all drained from their veins.

Godfield (Normal Garfield Form): I agree, but let's water our cactus before we head out to deal with the mosquito outbreak.

Y/n: Yes, father.

News Reporter: We interrupt this program for breaking news. A large swarm of mosquitos has been sighted in City Z. Mummified remains of attacked farm animals have also been found. If you encounter a swarm of mosquitos, flee immediately.

Then as Y/n watering his cactus plant, a mosquito began flying around Y/n before it landed on his hand as Y/n used his powers through his eyes to set the mosquito on fire until another mosquito flew by and this time, Godfield sliced the mosquito in half with his claws.

But then, more mosquitos keep appearing at their apartment as the two of them kept using their powers to kill the mosquitos coming into their apartment to suck their blood.

Then the Hero Association Emergency Broadcast started alerting everyone to not go outside due to the massive mosquito outbreak that could get them all kill with all of their blood drain that will leave them in withered, mummified husks.

Emergency Broadcast Announcer: This is an emergency evacuation warning. Threat level: Demon. No resident is to go outside under any circumstances. I repeat, no City Z resident is to go outside...

Then as the announcer continues to warned everyone about the mosquito outbreak, we see a young man with cybernetic armor, who is determined to take on the monster that started the mosquito outbreak on City Z.

Genos: Acquiring target.

Location: Somewhere around City Z

After the announcement was heard, everyone took the warning seriously and remained in their homes until the threat is eliminated.

Well, except for one that decided to rob a few stores since the whole city is empty from the mosquito outbreak that became his biggest mistake of his entire life.

Robber: Thanks to that warning, they're all empty! Like someone's gonna die from a mosquito bite. What's losing a little blood if I get all this? The wind...?

Then suddenly, a swarm of mosquitos started attacking him to feast on his blood until he is bone dry.

Robber: What the--?!

The Robber then started screaming in pain until he drew his last breath and blood as he now became a mummified husk like the other poor victims that the mosquitoes had drain their blood from as they took all of the man's blood to the queen aka the monster that started this outbreak, better known as Mosquito Girl, but as she absorbed the man's blood, she is not completely satisfied with the latest catch.

Mosquito Girl: Come on, you guys. That wasn't nearly enough. Go get some more for me!

Then the Lone Cyborg, Genos arrived at the scene of the crime to eliminate Mosquito Girl and save the city from her reign of terror.

Genos: Target acquired. I see. You make them suck the blood, then take it all for yourself. You must be controlling the mosquitos via some sort of signal. That would explain their mysterious behavior. So if I were to get rid of you, the leader, would the swarm disperse too?

Mosquito Girl: (Giggles) Our next meal is here. Go drain him dry.

Then the Mosquitoes swarmed around Genos, which didn't affect him at all since he is all metal and used his cyborgnetic powers to burn all the mosquitoes to death.

Genos: Incinerate.

He then used his Incineration Cannon to wipe out all of the mosquitos, shocking Mosquito Girl of what he just did as Genos is not gonna be defeated that easily.

Genos: I am about to eliminate you. (Charges up his Incineration Cannon) Stay where you are.

Mosquito Girl : You, eliminate me? (Giggles) Then go on and try!

Slap!

-Back with Y/n and Godfield-

Y/n: We got you.

Godfield: I think...we got them all.

But it wasn't over yet as one last mosquito flew out of the apartment and into the streets as both Y/n and Godfield are now really mad as they're about to blow a head gasket as they are not finished yet.

Godfield: (Angry Cat Growling​​​​​​)

Y/n: Damn...mosquitos!!

-Back in the battle between Genos and Mosquito Girl-

As the battle continues with Genos and Mosquito Girl, the fight is getting really tense as the cyborg is doing his best to take out the Monster before she could drain more blood from the city.

Genos: Incinerate!

But then, just as Genos was about to fire his Incineration Cannon at Mosquito Girl, but she is so fast that she managed to dodge the attack before ripping off one of his arms.

Mosquito Girl: (Laughs Evilly) Maybe a leg next? (Notices her legs are missing) Wait, what happened to my legs?

Genos somehow managed to get her back by ripping out her own legs for ripping out her legs with his other arm, showing her that he really means business.

Genos: Impossible. You cannot escape from me.

Mosquito Girl: Who the hell is that guy? He's gonna get me if I don't do something. The townspeople may all be hiding, but there are plenty of animals around.

She's not joking about that as the mosquitoes from outside the town managed to drain the blood the animals in the forest that is far away from the city that is enough to make her even more powerful than Genos.

Mosquito Girl: Come here, little ones. Empty all your stored juices into me!

Genos: So many. If she's been collecting blood fromm the whole town and beyond, then it may not simply be a food source for her. (Charges Incinceration Cannon) I should put an end to this as soon as possible.

Y/n: YOU STUPID MOSQUITO!!! GET OVER HERE SO I CAN BURN YOU TO HELL!!!

Then as Y/n and Godfield began chasing down the mosquito, they soon stopped running to see a massive swarm of mosquitos in the city.

Y/n: Dear God! That's a lot of mosquitos!

Godfield: I agree, that's enough mosquitos to wipe out at least the entire country or possibly the whole world. We must put an end to this outbreak as soon as possible.

Y/n: Right. (Charges up his power) It's time to exterminate those blood sucking insects to oblivion!

Saitama: Get back here, dammit!

Then Y/n and Godfield soon heard someone nearby as he saw Saitama running down the street chasing down a mosquito that he tried to kill with a can of mosquito killer, not even realizing that he is in the city with a bunch of mosquitos that are about to attack the entire city for the citizen's blood.

Saitama: You and I aren't done yet, ya little bastard!!!

Y/n: Who the hell is that guy?

Godfield: I don't know, and he shouldn't be out there with all of those mosquitos in the city.

Saitama: It's in my mouth! Pft! Pft! You little--! (Notices the mosquitos) Huh? What's that swirling over there? Are those...mosquitoes?!

Genos: You over there.

Saitama: Huh?

Genos: Evacuate now. That swarm is conscious. If it senses you, it will immediately attack.

Saitama: Seriously?

Y/n: Should we try to save them, father before the mosquitos' attack?

Godfield: I'm sure the cyborg can handle the attack, but as for that ordinary man with the bald head...I'm not sure if he will be alive or not when the mosquitos attack. (Thinking) Honestly, he looks like a normal guy, but for some reason I can't sense any form of limit within. Could he possibly have some sort of-

Mosquito Girl: (Evil Chuckle)

Godfield heard that evil laugh from the mosquito swarm before the entire swarm soon started attacking the city breaking through the windows on every building to break through to attack any human that are hiding away from the mosquito outbreak as he used his energy blasts to eliminate the mosquitos along with Genos with his Incineration Cannon, thus wiping out all of the mosquitos in the entire city.

Y/n: Uh, that seems a bit much, right?

Godfield: True, but I can sense someone within that swarm and since she can speak, I thought she would have at least human-level intelligence. But in the end, she was just a bug. She brought all the mosquitos together into one, easy-to-burn swarm. When the cyborg spotted her, he confirmed there were no living beings within 500 meters, so he should have been free to fire away. (Suddenly remembers something) Wait a minute, that guy might have--

Saitama: (To Genos) Man, you saved me. You're amazing aren't ya? You could say, you totally made them bug out! (Rimshot Imitation)

Y/n, Godfield and Genos were all surprised to see the bald man by the name of Saitama survive the blast, except for all of his clothes that got burned away from the blast. This man is really interesting to Y/n and Godfield as they never seen someone that managed to survive a blast like that before as Saitama continued to explain about his joke, unaware of what's about to happen next.

Saitama: Oh, I was just trying to make a joke about the mosquitos being bugs, and...

Then they heard the same evil laughter as Mosquito Girl looked completely different and a lot stronger due to the large amounts of blood from the mosquitos that drained the blood of the animals in the forest as she is now going to tear Genos into scrap metal with her new form.

Mosquito Girl: You Idiot! I no longer need my tiny little helpers. I mean...

She then showed how strong her new form is as she managed to destroy 3 tall building with a slash of her claws, causing Y/n, Godfield and Genos to gasp in shock of what she's now capable of.

Mosquito Girl: how strong I've become!!

Then she charged at Genos, and she managed to deal some real damage to the cyborg as she started attacking Genos high up in the air with a barrage of attacks, further damaging him to the point of Genos unable to fight back against her.

Mosquito Girl: Can't your punches kill a little mosquito?

Y/n and Godfield have never seen something like this happen before in their lives as their rage began to rise up and they're determined to kill the mosquito girl into oblivion to save the Lone Cyborg from certain death at the hands of the bloodthirsty insect girl.

Mosquito Girl: Weakling!

Genos: I get it know. The more blood she consumes, the more powerful she becomes.

Mosquito Girl: I think I'll have your head next!

Genos: I let my guard down. There's no chance of winning. All I can do is self-destruct. Forgive me, Doctor...

Then just before Mosquito Girl was about to kill Genos and the cyborg about to set off his self-destruct sequence to see if it's powerful enough to stop or even kill her, Y/n and Godfield was going to attack the monster before she could kill him until Saitama came in and slapped Mosquito Girl so hard, she was sent into the air with her blood sac destroyed when it hit the building, covering the whole side of the building with blood.

Y/n, Godfield and Genos were completely shocked of what just happened as the Mosquito Girl was stopped by one slap to the face like that.

Saitama: Bugs... they suck!

Then after Saitama defeated Mosquito Girl and saved Genos from certain death, Genos stopped him for a moment and asked him to be his disciple to become strong like him.

Genos: Wait a minute! Please tell me your name!

Saitama: Oh. It's Saitama.

Genos: I would like to be your disciple.

Saitama: Oh, okay. (Resumes going back home, but stops to look at Genos) Huh? What?

Then suddenly, the whole city area was back to normal along with Genos fully healed and repaired and Saitama's clothing as they are both surprised and confused is to what just happened until they saw a hooded man with angel wings and a golden halo that Saitama suddenly recognized from before.

Y/n: Well, that was fun. Time to head home.

Saitama: Wait! Hold up!

Y/n: (Turns to Saitama) Yes?

Saitama: Um...were you the one that destroyed those monsters a few weeks ago?

Y/n: Which ones?

Saitama: Uh...I think it's that giant naked man, the purple piccolo guy and that four-armed mole.

Y/n: Oh, those guys. Yeah, that was me. But I can't talk right now, I gotta lots of important things to do. See ya.

Saitama: No wait!

Before Saitama could stop him, Y/n had already teleported out of the city, leaving Saitama and Genos alone.

Saitama: Who was that guy?

Genos: Sensei! Who was that man?

Saitama: Could you cut off all of the sensei crap?

Genos: Yes, Master!

Saitama: Not master either! I need to have a word with this guy!

Genos: Then I shall locate where he lives.

Saitama: No need. I already found out where he lives. We just need to have a friendly chat with him that's all.

Genos: I see. That person must have something that he has to hide and since he managed to repair my body and restored the city back to its original state before the Mosquito Girl started the outbreak, we must reveal what kind of secrets that he's been hiding.

Saitama: You're right and I'm gonna figure it out myself! (Walks away)

Genos: Right! Wait? Now?!

Saitama: Yeah, there's a sale going on next week. Can't do it till then.

Genos: (Runs after Saitama) But Master!

Then as Genos and Saitama are on their way to figure out about Y/n's secret by staying under the radar by studying him before the bug deadline of the sales at the supermarket, we cut over to a secret base somewhere in the forest, where a scientist by the name of Doctor Genus received a report that Mosquito Girl was defeated in battle with one punch, which seems to interest the scientist about the bald man that defeated one of his most powerful creations.

Dr. Genus: Mosquito Girl was defeated? With one punch, you say? Oh well, she was merely a prototype until, after all.

Then the screen shows how Mosquito Girl was defeated, showing Saitama, butt naked as Dr. Genus asked the man that reported the defeat of Mosquito Girl is to why Saitama was naked.

Dr. Genus: Why is he naked?

Man: Unknown.

Dr. Genus: Well, whatever. He'll make an excellent specimen.

Man: Is there is more to report, sir. There happens to be someone that managed to defeat various monsters and restored City B after it was nearly destroyed.

Dr, Genus: Is that so? That is quite interesting.

Then the screen showed images of Y/n and Godfield together that defeated many other monsters and how he teleported Manugori to another dimension and restored City B. The scientist seems to be interested on both Y/n and Godfield after witnessing their actions across the cities, including City B.

Dr. Genus: Interesting...I never seen a human and a cat like that before that managed to perform such amazing feats. I'm sure those two will make the perfect test subjects for our research. We shall study their physiology by force if necessary. (To the Man) Send a messenger and invite them here, to this our "House of Evolution."

Man: Yes, sir.
