At long last this chapter will change thigs for this fanfiction. I am sorry if it took us a while, but hey I am the only one who decided to have this idea and not do some really messed or weird ass idea. Now let's get back to the story.

The Titans were now interested to see where this fight would go. This monstrous half woman half mosquito creature was killing people and animal left and right, but luckily that mysterious cyborg arrived to stop her reign of terror.

''So, I bet the cyborg guy is going to toast this mosquito chick with no problem.'' Said Wally.

''I don't know she seems really powerful.'' Said Starfire.

''We just need to wait and see what is going to happen.'' Said Nightwing.

''Wait I think they´re going to fight now.'' Said Donna.

The Titans were looking around in their monitor to see how the fight between the cyborg and the half woman half mosquito would ended up.

At Japan.

Mosquito girl saw this cyborg that killed millions of her children. She saw him as an interesting toy to play with. Genos however wanted to kill this monster right now.

''Incinerate!'' Said him releasing a powerful blast from his hand.

The blast would be powerful enough to kill any living creature, however apparently mosquito girl was a lot smarter than she appeared to be.

She managed to dodge the attack and fly at top speed towards Genos, her goal to tear the cyborg apart piece by piece.

''Urgh!"' Scream Genos dodge the attack however he saw that he lost an army because of that monster.

He saw the damaged and was of course pissed.

''Dammit.'' Said him.

''Heh! Shall I take your leg next?' Asked mosquito girl.

''Oh really? Well that you would make us even!'' Said Genos.

''Huh?! Oh no my leg!'' Said Mosquito girl seeing that Genos had indeed taken off her leg.

The fight was now on and the two were out for blood.

At Titans Tower.

The group was amazed by Genos reflex and power. Of course they wouldn't go to kill Mosquito Girl, but this wasn't their area so they couldn't dictate on Genos. They´re going to see what would happen next.

''Wow! Now that's fire power.'' Said Wally.

''impressive. I wonder who designed his weapons.'' Said Cyborg.

''This guy is really powerful; do you think he would accept an invitation to the Titans?'' Asked Beast Boy.

''I don't know, he was aiming to kill and we all know how we feel about this.'' Said Nightwing.

Back to Japan

Genos saw that now he was in a bit of disadvantage because of the lost of his arm. Things would be complicated but he need it to work things out, this how he wanted to repay dr Kuseno. He then tossed mosquito girl leg away and blow it off.

''It´s no use, you cat escape me.'' Said Genos.

Mosquito Girl then decided to make a cloud of mosquitos so she could think of a better plan of action.

'Who is that? If this keeps up, he´ll kill me!'' Thought her a bit scared.

She then decided to go for a really powerful attack.

''I´ll call all the mosquitos with the fifty-kilometer range of my control. All the people are hiding, but not the animals in nature.'' Thought her.

She then used a telepathic commando to call off all the mosquitos.

''Come to me! Pour into me the juice you have stored up.'' Said her.

Then a huge cloud of mosquitos swarmed her. Now it was hard to even see the sky over how many were around. Genos was starting to get worried.

''So many…if they have sucked blood from the whole town or an even broader area…. this could be troublesome to me.'' Thought him

Then he prepared the next attack.

While he was doing a certain bald man was running like a maniac and chasing a random mosquito like he was a fugitive.

At Titans Tower

The titans were now scared, this was becoming much more troublesome and somewhat really messed up. All those mosquitos could kill hundreds of people all around.

''This isn't good man, I can become a giant frog but I can't eat all of these.'' Said Beast boy.

''I don't your frog would be able to handle of that Gar.'' Said Miss Martian.

''How would any of us even handle something like this?" Asked Wonder Girl.

''A big bug spray?" Asked Wally.

''Not the moment Wally!'' Said Nightwing.

''What should we do call the league?" Asked Donna Troy.

''Well this isn't our jurisdiction, plus by the time we get there it will be already deal with. So if things keep going on we shall contact them.'' Said Nightwing.

''I hate doing this, but Dick is right. We can't interfere with monsters that the Hero Association has to fight, we need to see and be on the alert.'' Said Cyborg.

''I don't like this.'' Said Flash.

''Well it's the rule that it was established. We can't go full vigilante.'' Said Nightwing.

''Say that to your boss.'' Said Cyborg with a smirk as they kept looking at the screen.

Back in Japan

Genos was preparing another powerful blast, this one he hoped to kill most of the mosquitos.

''They are still gathering. Seems like the sooner I finish this the better.'' Thought Genos when suddenly.

''WAIT!' Scream Saitama running after the mosquito with a bottle of bug spray.

The mosquito flew away towards Mosquito girl, while Saitama looked pissed at that.

''This isn't over between us!' Scream him.

The cyborg just saw that scene in total confusion.

''Who is that guy!?' Thought him.

At Titans Tower.

The Titans just saw this 20 something bald guy appear out of nowhere. He must be a civilian because he didn't look all heroic.

''Who is that?" Asked Beast Boy.

''i dodnt know i dont live in Japan.'' Said Wally.

''Well I think he is a civilian that hasn't evacuated.'' Said Donna.

'He needs to get out there now! The battle is about to reach max capacity.'' Said Raven.

''Look at those mosquitos.'' Said Wonder Girl.

''I guess that monster is about to unleash her most powerful attack.'' Said Nighwing.

''This is bad.'' Said Donna worried.

Back in Japan.

Once Saitama stopped screaming at the mosquitos, he saw the calamity that was happening. A weird ass cloud.

''What´s that cloud?" Asked him confused.

''You haven't noticed those mosquitos?" Asked Genos.

''Those are all mosquitos!' Said Saitama in shock.

''You there. Evacuate the area. That swam has a will. If it notices you, it will attack.'' Said Genos all serious.

''Seriously?" Asked Saitamaa confused.

Soon the sound of the swarm kept growing and growing to the point that was shaking the windows.

''That sounds dangerous. You should get outta…'' Said Saitama but then he was interrupted.

The Swarm went towards the two and with a massive outburst managed to do a huge explosion the city. Similar to a nitrogen bomb.

BOOM

At Titans Tower.

The Titans present saw that attack and were horrified, regular heroes could have died in that attack and be seriously injured. That was all caused by freaking mosquitos.

''Woah! What that hell.'' Said Cyborg.

''How can mosquitos do all this?" Asked Wally

''This is about near 1 billion mosquitos; this could be enough to even destroy a person bones to ashes.'' Said Raven.

''We need to call the league and fast! Screw the jurisdiction, we are under attack by a monster who killed two innocent people.'' Said Nightwing.

''Wait look!'' Said Cyborg looking at his monitor.

The group just saw an counterattack explosion happening it was like another explosion managed to stop that other one.

At Japan.

Despite the collateral damage Genos was able to stop the swarm massive attack and that took a lot of his energy to do it.

''She talks, so I thought she possessed human intelligence. But she is just a bug, mosquitoes are easy to burn, but she sent them against me either me anyway. When I noticed you, I confirmed that there're is no other life within 500 meter radius…so I do no need to hold back.'' Said Genos.

However he remembered that guy that was just here.

''Oh no! That man got caught in the blast!'' Said Genos worried.

But to his schock the man was still there, all intact with some scratches and his clothes all destroyed. Which was impossible since that blast was powerful enough to turn human bones to ashes.

''Whew! Thanks! You´re amazing! What was that!? A big bug zapper?" Asked Saitama all chilled.

Genos just saw that scene and he was complete confused.

At Titans Towers

The Titans were also confused, because a person was near a super explosion that could have wiped out any living thing and he was fine. Blow off his clothes, but other than that he was ok.

''He survived!'' Scream Beast Boy.

''How?!'' Asked Donna Troy.

''I…I don't know…this doesn't make any sense.'' Said Cyborg confused.

''Wait look! She´s back.'' Said Miss Martian.

''What?" Asked Cyborg.

The groups aw that Mosquito girl was now in a new form and she looked stronger than before.

At Japan.

The duo moment stopped once they heard the evil laugh of Mosquito girl flying in midair.

''I had no more use for them! You idiots! After all…'' Said her with a smirk.

Soon she stop her sentence and disappear, she was so fast that appeared right behind Genos and takes his arm off.

''Uh!'' Said him in shock.

''Look how strong I´ve become.'' Said her with a smirk.

The cyborg was now in total shock, the mosquito monster was now above his level. She was so fast that was almost impossible to see her. She was just going down and destroying Genos piece by piece, the cyborg couldn't only do nothing as he was pretty much in shock and was too slow.

''Ha Ha Ha Ha! That punch wouldn't kill a mosquito! So fragile! Next time I will take off your head!" Scream her in pure joy.

Genos saw his life flashing before his eyes, he knew he was going to die there.

At Titans Tower.

The Titans saw that this was the right moment to act, that monster was stronger now and she was going to be a big problem if she gets out of Japan.

'This is now a serious issue!'' Said Beast Boy.

''He is going to need medical help.'' Said Miss Martian.

''We need to go to Japan now!'' Said Nightwingg.

''Titans go!'' Scream Cyborg.

Back in Japan.

Genos felt like there was no way out, he need it to use the self-destruction.

''The more blood she observes the more her physical abilities improve. I underestimate her. I can't win. I am sorry, professor.'' Thoguht Genos ready to explode.

''Ha Ha Ha ha.'' Laughed Mosquito girl in ecstasy when suddenly.

SLAP

Boom

The monster died right in front of Genos, he then stopped the self destruction as he saw the mosquito monster that almost killed him be turned into a bloody pool of blood. Who did this? Well, a certain bald wise guy.

''Damn, stupid mosquitos.'' Said Saitama with a smirk as he clean off his hands.

Genos was with his jaw dropped as he saw that mosquito girl was now fully dead and this man took her out with just one slap.

Saitama just looked around to see if anyone saw his remark, and then he noticed that he was alone.

''Uh oh yeah, there is none here.'' Said him a bit disappointed.

With the Titans.

The Titans were about to go out towards Japan, however a second can make a big difference since that was the time when Saitama arrived and they all saw the bald guy kill that mosquito monster with one slap. Of course, they were shocked.

''WHAT!'' Scream them.

The heroes couldn't believe their eyes, what that hell just happen.

''What was that?" Asked Starfire in shock.

''How…. what?' Asked Wally confused.

''Is that real? Did he just did that?" Asked miss Martian.

''No way! There is no way that bald guy did more damaged than a cool cyborg.'' Said Beast boy.

''Is he a kryptionian?" Asked Donna.

''We need send this to the league…NOW!' Scream Nightwing.

In Japan

Saitama was seeing that the job is done so he decided to head home.

''Ok mosquito killed, I guess I am going…'' Said Saitama ready to head home when Genos stopped him.

''Wait!'' Scream Genos.

''Uh?' Asked Saitama confused.

''I am lone cyborg fighting for justice. I am called Genos! Tell me your name!''

''Saitama.''

''Take me as your disciple!'' Said Genos.

''Uh?" Asked Saitama confused.

This would be the start of a great partnership.

At the Justice League watch tower.

The Justice League were having another daily meeting, just talking about what they did today, villains they fought, talk about the unseen monster, the usual. However, this all stopped when an emergency alarm was ruined.

Emergency!

''What happened?" Asked Superman.

''We got a emergency communication coming from someone.'' Said Wonder Woman.

''What are you waiting! Put on screen.'' Said Hawkman.

Soon Nightwing appeared on screen and he looked terrified.

''nightwing what happened?'' Asked Batman.

'We were looking at Japan, looking for the mysterious person that killed those monsters. When suddenly a half girl half mosquito girl appeared and started cause chaos, but that's not why I am causing this meeting.'' Said Nightwing.

''What is this all about?" Asked Red Tornado.

''Watch!"' Said him.

Soon they all watch the fight between Genos and Mosquito girl. They saw the potential in Genos and the threat that this monster oppose. Then the real thing happen, when Saitama showed up and killed her with just a slapped.

Everyone was speechless at that. To cause a death like that you would need a lot of strength, almost superman level of strength.

''What that hell…'' Said Captain Atom.

''how?" Asked Hawkgirl.

Martian manhunter then had his PTDS coming back when he saw Saitama. Everything came back to him.

''Its him!'' Scream the Martian.

Everyone looked at him in wonder.

''What do you mean Joon?" Asked Green Arrow.

''The man who killed Vaccine Man in one punch, its this person.'' Said him in shock.

The heroes all look in horror, so this was the person that had the immeasurable amount of strength that could rival superman?

''Seriously that bald guy?'' Asked plastic man.

The heroes were now speechless but a bit relived…they have the culprit.
