Hey there guys, I felt you all deserve something nice after my long hiatus. I wanted to post this after Christmas, but I got held up. I am still amazed that people haven't made stories like this, my point is what if Saitama was in the DC Universe, but like since most of the stories always happen in the United States and even in Canon Saitama is just a random hero for the people it would make sense why people wouldn't know about him.

I know some of you either didn't get what I was saying or something. Either way lets get back to the story.

Also, this has been done for a month and I decided to post now so you guys can be happy. I hope you all enjoyed.

At the battleground.

Saitama was seeing Superman sending Armored Gorilla to the authorities while Batman had informed him that the Justice League would be coming at any second.

''How long are we going to wait?'' Asked Saitama.

''Just about 5…4…3…2 and…'' Said Flash and then a great amount of light appears.

Soon the Justice League all appeared on the scene, for anyone in the world that would be something to be statistics about it.

Genos felt a little bit of a nervous moment, he heard tales of the Justice League the world most powerful super hero team that wanst the Hero Association. While the association dealt with monsters and villains in Japan the JLA tends to fight for the entire world. Some heroes would even left the association and join the League many teams or even be partnered up with them.

''The Justice League! It's incredible I never imagined to see the current roster.'' Said Genos

''Do they all carpool together? I bet is crammed.'' Said Saitama.

The League went to the founders to ask about the current situation.

''So monsters that are a step on Evolution?' Asked Captain Atom.

''Yes, they even had some human's genes but just a few.'' Said Superman.

''The remaining one?'' Asked Hawkgirl.

''Being hold.'' Said Superman

''And the bald guy?'' Asked Hawkgirl.

''Is he here?'' Asked Plastic Man interested.

''Yes, over there.'' Said Superman pointing to Saitama.

The bald hero didn't know what to say to all those weird people looking at him, he was more confused than concerned at the moment.

''Uh…hi?'' Said him.

The entire League looked at him and they all had various types of opinions about all this.

''Wow he doesn't look that cool not even in person.'' Said Plastic Man.

''He doesn't look threating, but my animals instinct said otherwise.'' Said Vixen.

''Let see about this.'' Said Hawkman wanting to see if all that strength was real but he was held back.

''Carter please.'' Said Hawkgirl holding him.

''Hey buddy, heard you are an interesting guy. Nice to meet you, Green Arrow.'' Said the archer trying to be friendly.

''Hi.'' Said Saitama confused.

''Sorry for him, the trip messes up with your head. Black Canary by the way.'' Said the blonde to him.

''My sensors indicate a powerful force. 'Said Red Tornado.

''And my magic is going absolute mad near him. Its like…he is something that reality can't accept.'' Said Dr Fate.

''I don't like this one bit.'' Said Zatanna.

''He doesn't feel like a treat, but if he is really that strong having him around would be super beneficial to the League.'' Said Black Lightning.

''Agreed, but we need to see where that force comes from.'' Said Jon Stewart.

Saitama saw all these people talking about him and introducing themselves and he felt super awkward, he wasn't the best in social gathering.

''Uh thanks, I don't know what else to say.'' Said Saitama.

''Master, I think they just want to work alongside you.'' Said Genos.

''Master?'' Asked Green Arrow.

''Yes, I am Genos and I am Master Saitama pupil.'' Said Genos.

''We haven't agreed on anything yet.'' Said Saitama.

The League decided to leave that question for another time, they know what the mysterious person look like and even knew their name, but for now they have to deal with this Genetics thing first.

''We can deal with this later. First of all what is this whole genetics thing all about? Any leads?'' Asked Black Lightning.

''The gorilla said that he was working for The House of Evolution.'' Said Wonder Woman.

''The House Evolution? What is that?'' Asked Plastic Man.

''I have some information given by armored Gorilla. However, I have a good summary so we don't waste much time. Could I?'' Asked Genos.

''Please.'' Said Superman.

''The house of Evolution is a mysterious organization that have been operating in Japan for a century. They plan to harvest superhuman physiology for his research on Evolution. He probably send assassins because the League was with Master.'' Said Genos.

The League took the information and decided to go on with it. That was enough to handle and go with a plan, now they need to find a location.

''What should we do?'' asked Dr Fate.

''We will find the House of Evolution headquarters and stop these abominations.'' Said Batman.

''The monsters that they have send where that tough, but I can tell there is more coming out.'' Said Superman.

''Yes, there was a lion, a mole, a praying mantis and so much more. I can't even imagine what kind of experiments are those.'' Said Hal Jordan.

''Man, these must've been some wicked monsters.'' Said Green Arrow.

''Where are the others? Did you all send to jail too?'' Asked Plastic Man.

''You're stepping on the lion.'' Said Batman

The league all looked at the ground and saw the great amount of blood and guts all around. It looked like a massacre just happened.

''Ew.'' Said Vixen sicked by that.

''What happened!'' Asked Plastic Man.

''Him!'' Said Batman pissed as he points at Saitama.

''I just punched the lion, that's all.'' Said Saitama.

The League were beyond shocked by that, plus the look on the founders just confirm that yes, that bald guy was that powerful.

''You really need to hold back on your strength man. That can be dangerous.'' Said Jon Stewart.

''Dude you've should see in person. Like…he destroyed them like if they're paper.'' Said Hal Jordan.

''I mean its my apartment and he broke my ceiling.'' Said Saitama.

''A bit excessive don't you think.' Said Black Canary.

''Look man, we deal with monsters all the time, but we don't just make them explode. Yes, we do that sometimes but not often.'' Said Green Arrow.

''Well sorry, I didn't know that I mean every monster here in Japan gets killed so I though its ok.'' Said Saitama.

''And it is master, if you kill a monster in self-defense there are no sort of procedure against you.'' Said Genos.

''We will discuss that later, but you shouldn't just kill every creature you see. That's not very hero like.'' Said Zatanna.

''Speaking of which what kind of hero are you?'' Asked Black Lightning.

''A hero for fun.'' Said Saitama.

The League all had most of a look of ''WHAT!'' with their jaws hanging, they look at the founders and they had a look of embarrassment and even Batman had a look that mean ''Yes, he is telling the true''.

''He is not in the Association. I checked his wifi and nothing.'' Said Batman looking pissed, he didn't know if it was good or bad that this idiot wasn't in the Hero Association.

''What?'' Asked Saitama confused.

''You invaded Master privacy!'' Scream Genos.

''I am doing what is best for the safety of the world.'' Said Batman.

''Uh…what do you mean apply?'' Asked Saitama confused.

''I mean he is at least fighting for good.'' Said Black Canary.

''He is not registered; this is more like a vigilante work than a hero work.'' Said Batman.

''You are call my master a vigilante! How dare you.'' Said Genos.

''Its ok Genos, I don't care.'' Said Saitama.

''Saitama, can I call you Saitama?'' Asked Green Arrow.

''Uh yeah?'' Said Saitama.

''You need to register on a superhero team before deciding to fight crime, this way the government keeps an eye on you and making sure that you're ok.'' Said Green Arrow.

The explanation appeared to be simple but Saitama was still not sure about all that, he was still feeling a little bit lost.

''But I just put on my costume and went out fighting. I mean there is nothing wrong with that. Do I have to register?'' Asked Saitama sounding like he was lost.

The League was now feeling a bit shocked, its like this guy was refusing to cooperate with them or something like that.

''Is he an idiot?!'' Asked Hawkman.

''Carter.'' Said Hawkgirl in shock.

''Any leads for that strength?'' Asked plastic Man.

''We are thinking Kryptonation or something near.'' Said Hal Jordan

''Ok, we can discuss this later. We need to handle the House of Evolution first.'' Said Wonder Woman.

The Justice League all nod at that, they would deal with Saitama after dealing with the House Of Evolution.

''Listen, while we were fighting Armored Gorilla, I picked up the localization of their base. It was simple, just crossing the signal of transmission. It's a few hours from here.'' Said Genos.

The League was impressed by Genos level of dedication into finding the culprits, this was kind Batman style of information gathering.

''Impressive.'' Said Red Tornado.

''Yeah kid, would you like to come with us? I'm sure we can settle you with a good team.'' Said Black Lighting.

''I appreciate the offer, but I decided to become a disciple for Master Saitama, I wish to become stronger just like him.'' Said Genos.

The League all looked Saitama who just appeared to be lost.

''Uh what?'' Asked him.

The League just felt bad for Genos, this didn't look like a good guy to get your training.

''You're kidding right?'' Asked Jon Stewart.

''Whatever is the case don't waste your time with this buffoon.'' Said Hawkman.

''What? Why are you mad chicken guy?!'' Asked Saitama.

''I am a Hawk! From the planet Tharnagar!'' Scream Hawkgman grabbing Saitama by the collar.

''Uh…ok.'' Said Saitama confused.

''Listen, we don't have time to deal with these arguments. We need to stop the house of Evolution'' Said Superman.

The heroes decided to hear the Man of Steel, he knew what was the best and at the moment they needed to stop this mysterious organization.

''Armored Gorilla said that there are more monsters, including one that is set to be the Top of the Food chain.'' Said Genos.

''Genos is right! We need to stop this guy at any cost, I said we go to his or her place and put an end to these weird monsters before they destroy more things.'' Said Saitama all serious.

The League was now impressed with Saitama, that was a legitimate good motivation and he sounded eager to help.

''Woah! I guess he isn't half bad.'' Said Flash.

''I am impressed Saitama; I didn't expect to see this side of you.'' Said Superman all happy.

''Of course, tomorrow is a bargain day on the supermarket. If we don't do this now, I can't go with you all.'' Said Saitama and that completely destroyed the whole mood.

''THAT'S YOU REASON!'' Scream most of the league.

''Yes, I mean its bargain day I cant say no to that.'' Said Saitama all calm.

The League wanted to face palm at that, but it was just too much to process at once.

''I…I…'' Said Black Canary lost in words.

''You are kidding right! Immense power on that idiot!'' Scream Hawkman more pissed than ever.

''Hey, don't insult my Master!''' Said Genos.

''Genos…please get a new master.'' Said Captain Atom.

''No, I need to know how to get stronger. And Master Saitama is clearly the strongest.'' Said Genos.

''You can get stronger with us, it will make much more sense than with him.'' Said Green Arrow.

''And have my memories tangled with it. No thanks, I heard rumors of what you all do with heroes who don't follow your rules.'' Said Genos a bit serious now.

''Woah! Where did that came from?'' Asked Hal.

''Let's just say I know the truth. What've you all did to your villains, Sanctuary and the Omac Project. All these news are reason of why most of the Japanese don't go to the league.'' Said Genos.

Batman just grind his teeth at that, somebody must've told the Association about these events and painted the league bad towards the heroes of Japan. It was either Metal Knight who did that or somebody else.

''Master, I've the location of the hide out if we go now we can get there in a few hours.'' Said Genos.

''Sounds good, we will take a head start. See you all there.'' Said Saitama and Genos running off.

While the two were off running ahead the League was just standing there, questioning about the enigma that is Saitama.

Some of them are still in disbelief that someone that powerful could be that dumb or not serious. Like what was that.

''Superman…please tell us that he is not the One Punch Man that for real.'' Said Plastic Man.

''We saw him display his strength, and its real. Now I know Saitama has his flaws but…'' Said Superman but Hawkman was the first one to speak.

''He is an idiot!'' Scream Hawkman.

''Carter!'' Scream Hawk girl trying to stop him but that wasn't enough.

''He is! Don't tell me that you're expecting him to join the League?! That would be a disaster.'' Said Hawkman.

Superman didn't know what to say, lucky for him Wonder Woman was already there with some words.

''I understand you're frustration Carter Hall, I am too jealous of his power, but I shouldn't display anger in front of everyone.'' Said Wonder Woman.

''Really Wonder Woman? You're jealous?!'' Asked Plastic Man surprised.

''He has a strength that can surpass a God. If I had that power of his no God would've hurt the Amazons ever again.'' Said her all serious.

The League need it to plan an idea and fast, they didn't know what could happen if Saitama is manipulated or turn evil. He appeared to be way too much for the heroes to handle, so they need to see if they can find a way to work with him.

''We dealt with weirder stuff, granted this si new but we can fix this.'' Said Flash.

''Agreed, Saitama might appear odd but his heart on the right place.'' Said Superman

''We can discuss this later, right now we need to stop these creatures before they get more aggressive.'' Said Aquaman.

''To the house of evolution.'' Said Superman as all the heroes either fly or are carried out to arrive at their destination.

The group would've met up with Saitama and Genos, even offering them a ride but the elephant in the room which is the bald hero was still a lot to process before they can move on.

At the House of Evolution

Dr Genus the leader scientist of the House of Evolution saw in his computer that two of his most powerful agents have been killed.

''Impossible, Beast King and Dragon Ground were killed. How come?! They are the strongest members of the Organization.'' Said Dr Genus pissed.

The Doctor was near a little bunch of clones that he made of himself, after spending near a century working with the DNA of various species, he felt that that he need it to gain youth so he can see his creatures create havoc. So that's why he cloned himself innumerous time.

After seeing that the monsters were killed and looked on the monitor and saw who was arriving, the Justice League alongside two new members that he has never seen before.

''Oh, the Justice League. They've the heavy lifters, I didn't expect to send him out so soon, but I guess its time. Clones, release Carnaage Kabuto.''

The army of clones just look at that in horror.

''What! You cant release him he is too unstable. Besides he is not strong enough to handle Superman! You're going to throw the House Trump Card in the trash if you do this.'' Said one of the clones.

''Calm down. Carnage Kabuto has the same DNA as a kryptonian, plus he has been receiving sun light for months, he is powerful enough to slaughter the entrie league. Besides there is no creature alive that can kill a Kyrptionian so easy, outside of Doomsday.'' Said Genus with a smik.

The clones all shake in fear as they were about to unleash the dangerous creature, little did Genus know that what would cause so much problem wasn't going to be the League but a certain bald guy.

So yes, we have a finished chapter and I am glad that I had most of the League speaking in this one. It's a blast to create something fun for people to read and have a good time.

Also, I know that some pronunciation, punctuation and pacing aren't good, but like I said I am not a major in English, heck that's not even my main language, I am still amazed that I wrote so much in English so far.

I've seen a lot of people complaining on how Batman acts in this fic, listen I like Batman but there are times that he needs to know that he ''no kill rule'' is mostly for him. In the One Punch Man world monsters and aliens that attack people are sentenced to death, I don't remember one human villain that was brutally killed by the heroes, I mean Psykos was almost, but she escaped. It also because I read the series Hitman complete for the first time, for those who don't know Hitman was a comic series made by DC written by Garth Ennis before he went mad, the series is about a hitman in Gotham so of course Batman hates him, but the main character only kills horrible people, like drug dealers, rapists and other criminals, he doesn't go after Batman rogues gallery and of course Batman tries to arrest him in every opportunity. Heck after an event where Hitman saves the JLA Batman tossed him to a police station but sometimes Batman is an idiot and forgets that only 6 cops in the entirety of Gotham listen and respect him, the others don't like him or are corrupted. So yeah, while Batman is a great character he is a really damaged individual that isn't perfect, and Saitama is going to be fun just to mess up with his whole paranoia persona.

I hope you all have a great time and be safe. Thanks for being patient.
