Hi there, here is the new chapter of this series. This has been too much fun to write, seeing the DC Heroes having to deal with Saitama antics and how the events of the Manga would go. I am not trying to make a fanfic about ``the right form of heroism``, I want to make a fun fic where the One Punch Man character live in the same world as the One Punch Man ones.

Also, I got some guest reviews telling me that this fic is unoriginal. I am not going to do every arc beat by beat with the DC Heroes, I am doing more with this arc because its to supplement to the Justice League what they are dealing with. I just want to see if you all are satisfied with this. I am just a guy writing and I am not trying to make this my job.

Now let's get to this chapter.

At Hideout

Saitama, Genos and the Justice League walked calmly towards the hallway. It was kind of creepy, but having the strongest heroes on Earth would make anyone calm.

"This underground base sure is spacious.'' Said Saitama.

"Of course, if this is where all those monster came from then they need a lot of space to move around.'' Said Hal Jordan.

"If there are more of the likes from the ones, we faced in the neighborhood we can defeat them if we team up.'' Said Batman.

"I agree, everyone be alert for what kind of creature might be spotted.'' Said Superman.

"I am getting excited.'' Said Saitama.

"Me too! I love tangling with some monsters.'' Said Plastic Man shape shifting his body.

"I'm sensing life forms ahead. Which is weird they all have the same body heat, almost identical to each other.'' Said Genos.

"Do you think they are clones?'' Asked Flash.

"Stop!'' Said Genos to the entire league.

Before the whole league listened to the teenager cyborg, he had a look of horror in his face.

"Master! There are two life forms ahead of us! Be prepared everyone.'' Said Genos.

Soon they heard the sound of insect wings, however instead of being annoying was much louder than they ever heard, it was actually scary.

"What that..'' Said Superman using his enhanced vision to see the creature coming towards them.

Then they saw a giant monster bug, it was like a muscled bound dung beetle on steroid with a human face. He was horrifying and he was holding a man on his hands who looked like was in intense pain.

"Is that a giant bug?!'' Asked Black Canary in shock.

"Yes, be on alert he is strong.'' Said Superman.

Carnage Kabuto saw all those heroes and was started to get excited. However he wanted to see who was the strong being that Dr Genus was talking about it.

"Oh, there are here! This is so good. Look at all these people! Now which one is the one that you say is the strongest?!'' Asked Carnage Kabuto.

"The bald one! The one with a yellow costume.'' Said Genus.

"Then you don't need all these heroes, right?'' Asked Carnage Kabuto going on Maximum speed and tossing Dr Genus to the side as he went to attack the heroes.

"Look out!'' Scream Batman.

The giant bug monster was now getting excited as he was filled with adrenaline and ready to kill as much heroes as he could.

"Everyone, take him down!'' Scream Superman.

As the heroes went to attack the giant bug Carnage Kabuto went to attack the first hero that was nearest at his vision, which turned out to be Genos and he tossed him into a wall with full force.

BAM

"Genos!'' Said Wonder Woman.

"What?'' Asked Saitama in shock to see the cyborg being tossed aside.

The creature soon stand in front of the entire league plus the two new heroes, he was smirking while the heroes were now pissed.

"Who are you and what is your purpose?'' Asked Superman.

"I am carnage Kabuto! And I've got a battle test room! We can go all out and test our strength. Once I killed all of you I will deal with him and see what is his power.'' Said Carnage Kabuto with a murder glee looking at Saitama.

"Why do you want that?'' Asked Hawkgirl.

"I want to see the true strength of someone with incredible strength. I was created to surpass the strongest heroes on Earth. I have ways to destroy Superman, Wonder Woman, Green Lantern and so much more, but him I have no idea what kind of power does he has. This is all I want.'' Said Carnage Kabuto looking at Saitama with a smirk.

The heroes felt that this monster would be different from all the others monsters that Saitama killed, this one would be very different since he knew how to deal with the likes of Superman and so many other heroes. They felt that Saitama wouldn't stand a chance.

"Saitama don't do this. He is stronger than those other monsters that you faced, let us handle this.'' Said Superman.

"I have too! He hanged Genos like Modern Art! I will kick his ass!'' Said Saitman pissed.

The heroes didn't know what to say about that, he sounded serious but it was kind of silly. Carnage Kabuto was kind glad that his wish was about to be granted.

"well if it's a fight that you want…then let's have.'' Said Carnage Kabuto going towards the battle room.

Soon all the heroes went and followed the monsters, Dr Genus managed to get unnoticed by the heroes, they were possible too focus on Carnage Kabuto that they didn't noticed him. However, he knew if they survived he would spent the rest of his life in prison, but he wanted to see where this fight would go.

"What do you all think? This is where the creatures all fight! We see who is willing to live or die! Now let's begin our brawl!'' Said Carnage Kabuto all excited for the fight of his life.

"It's like he wants us to gang on him.'' Said Jon Stewart preparing his ring.

"Yes, but not all of us can handle this creature alone for a second. Its like a muscled up and more crazy version of Amazo.'' Said Aquaman.

"We can find an opening and hold him down.'' Said Martian Manhunter.

"So are you going to fight him too? I thought it was just me wanted.'' Said Saitama.

"I am going to try to hold him off and then we can start ways of knocking him out.'' Said Superman all serious.

"Do you need a moment to get your mind fixed?'' Asked Captain Atom.

"I am not scared; this guy doesn't look that strong.'' Said Saitama all cold.

The league all just looked at that in surprise, Saitama just said the monster didn't look strong and was all calm, what kind of power do you need to have to say that all relaxed when seeing a monster of that size?

Before they could do anything a large wall of flames was released and covered Carnage Kabuto from toe to antler.

Boom

The league was surprised was the monster came out of the flames without so much a scratch.

"Fire?'' Asked Hawkman confused and then they saw who was responsible.

"Genos!" Said Batman.

"He is still on his feet after an attack like that?'' Asked Zatanna in shock.

"Dawn kid is tough.'' Said Green Arrow with a smirk as he prepare his bow.

"Master, please let me assist you.'' Said Genos trying to catch his breath.

"You are still alive?'' Asked Carnage Kabuto confused.

"Don't you dare attack him!'' Said Wonder Woman launching towards the monster with her sword.

The heroes soon started to attack the monster. Wonder Woman was slashing him with his sword and was doing not much damage, the Hawk couples were attacking with a mace and an axe and nothing else was happening. The green Lanterns was bombarding him with attacks, Zattana was using her magic and even Superman was using his laser vision. The rest of the league was going towards Genos to assist the poor cyborg, however even with all those attacks Carnage Kabuto wasn't feeling like to fight those heroes just yet, he felt like killing Genos first to have a lust for blood for a perfect combat.

"That kid is going to be my first kill of the day!'' Scream the giant beetle.

"Genos look out!" Scream Flash but it was too late.

Genos tried to escape the attacks from the giant monster, meanwhile Red Tornado made a bunch of tornados to confuse the beast. It worked for a few seconds which was enough time for Wonder Woman to attack once again with her sword.

"All these things are nothing.'' Said Carnage Kabuto with a smirk.

Then after that Genos activated his super speed to counter attack. In an impressive foot he managed to get back up and stood towards the giant beetle monster, he then aimed his arm towards the creature with determination.

He attacked with Machine Gun Blows.

Bam

Once that great amount was being bombarded Captain Atom and Shazam started to attack with atomic blasts and magic thunder.

Boom

Red Tornado assisted with a big tornado as Superman used his heat vision, plus Black Canary was using her Canary cry and Green Arrow used some of his big explosions arrows. Despite all that the creature wasn't even bothered by all that.

"Ha Ha. That doesn't even tickle me!'' Said Carnage Kabuto with a smirk.

Soon the creature started to charge at full force shoving evry hero that he could, he reached toward Genos and launched a really hard punch towards the teen Cyborg.

"AAAAAH!'' Scream Genos in pain.

Saitama saw that scene in surprise, he didn't expect to see that amount of violence towards the cyborg. The bald soon catch Genos who was ready to hit the floor, but he caught him.

"Genos!" Said Plastic Man in shock.

'Master…please…let me keep fighting.'' Said Genos.

"Your face is broken! Don't push yourself too much.'' Said Saitama in shock.

"We can fix him in the Watchtower, but later. Stay put while we fight him.'' Said Vixen.

"No, I will keep going.'' Said Genos trying to get up.

"What! You are done! Kid just stays down.'' Said Green Arrow in shock as he keeps loading arrows towards Carnage Kabuto.

"Genos stop. You are done, I can tell that your limit is about to be reached. If you don't stop, I will shut you down.'' Said Batman.

"That's a bit harsh.'' Said Saitama.

"No, I can still fight!" Said Genos.

The teen cyborg soon started to charge his arm; he soon was ready to release a powerful attack.

"Get out of the way!" Scream Genos all serious.

The heroes all heard that and saw the arm canon, they got out as fast as they could and Carnage Kabuto was confused why everyone stopped to fight him, and then he saw the cyborg aiming at him.

"Uh?'' Asked Carnage Kabuto.

"AAAAAAAAAAAAAAAAAH!" Scream Genos releasing his most powerful attack, a beam attack that could rival Captain Atom powers.

Carnage just saw that attack and was only annoyed, he took a deep breath and blow the attack away with his own breath. The craziest thing is that it worked.

"Did he repealed that with his breath!'' Said Wonder Woman in shock.

Soon the attack went towards the heroes.

"Look out!" Scream Hawkgirl.

Superman shielded most of the attack to protect the heroes that could survive this sort of attack, the green lanterns made a bubble shield to survive and even with the defense shield the heat was absurd.

"Holy hell! What kind of power does this come from?'' Asked Jon Stewart.

Once the attack was finished everyone was a bit shaken. Superman had his uniform a bit turned off and burn it but overall, he was still ok. Most of the heroes were fine, just a bit sweaty because of their heads.

"Is everyone ok?'' Asked Superman.

"A bit dehydrated, but overall fine.'' Said Batman.

Saitama was starting to get annoyed at that bug and he soon saw Genos who felt a bit different.

"Genos! Are you ok?'' Asked Saitama.

"Yes.'' Said Genos

"No, that head is not!'' Scream Saitama.

"Ha ha ha. That Little cyborg is done already.''

"Why you…now I 'm looking forward towards this!'' Said Saitama now excited to fight.

The Justice League was now curious to see the mysterious powerful bald in action, the founders saw Saitama strength and it was something to be admired, but this monster seemed like something completely different.

"Saitama, don't do it!'' Said Superman.

"What?! Why?'' Asked Saitama.

"We still don't know if he has a weakness, plus his strength is overwhelming. We need to still fight together.'' Said Batman.

"Nah, I want to take my shot on this thing.'' Said Saitama excited to fight this monster. Maybe he was going to give him a good fight.

"Listen! This is not a small monster you find on Japan, this is a serious threat! Dragon Level!'' Said Hawkman.

"We are going to keep fighting him with you. If you don't keep up then you will get left behind.'' Said Jon Stewart.

"Oh really, you're all still going to fight me? Well then bring it own, I will put more attention on this bald bastard, once he is done, I will kill you all.'' Said Carnage Kabuto.

While the monster was about to attack the Justice League again Dr Genus re appeared, all injured as he saw his greatest creation ready to fight the world greatest heroes again.

"The worst demon ever created by the House of Evolution. Now Carnage Kabuto, show me how a member of the human race in its current form fights against a monster that is the ultimate form of artificial evolution. Even with the genes of Kyrptionias and other aliens you're probably the most powerful creation ever created in the whole universe.'' Thought Dr Genus.

Saitama took a step forward as a good number of the Justice League members walked near him, for the first time they saw the bald hero looking seriously, that was a fresh look on him.

"Keep Carnage Kabuto down, we can still take him down.'' Said Superman.

"Superman, me and Dr Fate will try to heal and fix Genos. Don't worry about us.'' Said Red Tornado.

"Saitama, please restrain yourself. He doesn't need to die.'' Said Superman.

"Ok.'' Said Saitama all simple, just excited to fight.

The monster saw the heroes, but he was only focused on Saitama, excited to see the strongest person in the room.

"You're supposed to be strong?!" Asked Carnage Kabuto.

"don't disappoint me, ya hear? You're this place's ultimate weapon, right? You're clearly different form those guys this morning. You're positively brimming with confidence. So bring it own!'' Said Saitama all excited.

The monster went to give a kill blow at Saitama, the League saw how much energy the creature still had in stock. He was so fast that it was hard to keep track.

"He's fast!'' Said Genos.

"I can stop it!'' Said Flash.

"Wait!'' Said Martian Manhunter sensing a mood change.

Carnage Kabuto was about to attack Saitama, but once Saitama looked at him he backed down as fast as he could.

"Did he just ran away?!'' Asked Back Canary confused.

Everyone was now confused, why was this creature backed away, he was filled with confidence but now he was looking like a scary children.

"Martian Manhunter what is happening?'' Asked Batman.

"I sense fear and horror.'' Said Martian Manhunter.

"What?'' Asked Vixen in shock.

"The ring is also sensing something strong and dangerous. It's so crazy that this thing wouldn't stop blinking.'' Said Hal Jordan.

"Mine too.'' Said Jon Stewart.

"How the hell is this happening?'' Asked Hakwgirl.

The heroes all looked at Saitama in shock, did he made the big creature ran away in fear. Not even Superman had this kind of presence even after all these years.

Carnage Kabuto was sweating in fear, he looked at Saitama with confusion and disbelief.

"If I had attack just now, he would've killed me. What's with this guy? He's full of openings. But my instructs are blaring a danger signal at me.'' Thought Carnage Kabuto full of fear.

"Uh? Are you ok?'' Asked Saitama confused.

"Youuuuuuuuuuu! How did you get such power?!'' Asked Carnage Kabut wanting to know.

"He won't tell you! Saitama don't say a word.'' Said Superman.

The bald hero was confused at first, but he felt that everyone wanted answers for his strength. He wasn't the smartest person, but he could tell that they wanted to know how did he got this sort of power. He soon went serious and started speaking.

"Do you wanna know my secret? Alright, everyone listens up, specially you Genos.'' Said Saitama.

The room went quiet, the heroes, mad scientist and the monsters were all in shock that the powerful man would give his secret away.

"The reason for his strength. He will just tell out of the blue? What could be.'' Thought Batman.

Everyone was tense as Saitama was about to tell his secret.

So yes, I ended here the next chapter will be the secret, reactions and the end of House of Evolution. After this I will do some original arc, because after this is the Sonic Arc and that's its not that much, we get Sonic but just that.

This is a very fun fic to do and I see that its getting popular. I hope you all have a good day and again sorry if there are some grammar errors.
