Saitama slammed her hands together impatiently veins appearing on her face. She glared menacingly at her hands in which she captured the mosquito in. "I got you" she whispered furiously. She had put all her power into that one slam so there was no way in hell the little bastard had survived.

As soon as she did so the mosquito flew out of her grasp and buzzed away. She was sure to god this thing was messing with her and she was done playing games. At first she wasn't really fazed but now she was seriously pissed.

A look of murder spread across Saitama's face as she grinned angrily; veins and rage filling every corner of her face. She grit her teeth in frustration as the target yet again escaped her grasp.

"Damn mosquito's" She hissed angrily under her breath. This one truly lived up to its name of being a massive pest; but she would kill it in the end. There was no way she would let it survive.

Meanwhile elsewhere in city Z

Genos leapt across a building quickly lunging at the Mosquito creature; he would kill her no matter what it took. He lunged a punch at her only to miss her head; she gripped his hand in one of her claws pulling him close to him laughing menacingly.

He stared her down his eyes intent with hatred; he would get rid of this enemy no matter what. There was no way he would fail against her with all of his power and technology.

His arm whirred producing a blue light to which he propelled away from her instantly. He lunged against the building again propelling at her only to be grabbed by one of her clawed arms again.

She slammed down on him with one of her claws sending him flying towards the street. He used him arms to create a helicopter generation allowing him to land without receiving any damage.

He raised his arm again to throw another blast at her; he would get rid of this bug bitch effortlessly. She was tough but she was no match for firepower. "Incinerate" he repeated adamantly. He would make sure she was killed; even if it took a unnecessarily long time to do so.

She lunged at him grinning wickedly dodging all of his attacks. Was this all he had? Just cheap fire power shots against someone like her? Surely he had no idea of the enemy he was fighting against.

Genos was thrown for a second but stood firm while his left arm was torn off. Being a cyborg he didn't feel pain; and he wouldn't go down easily. However, he would be sure to return the favour later. This woman was just cocky because he hadn't yet taken her down.

She laughed jeeringly as his arm sat on her extended spike hanging in mid-air. Not so powerful now was he? "Maybe a leg next time?" she teased wickedly. She could tear him apart easily peace by peace; but she was enjoying playing this game.

Genos turned to face her menacingly; this was just a game to her. He was her new form of prey to use her new found powers on; disgusting. Enemies who took pleasure in inflicting harm to their prey were the worst.

Suddenly she felt her body grow heavy and her legs felt lighter. She looked down to realize both of her legs had been removed from the knee down. "What the? What happened to my legs?!" she questioned worriedly. When had they been taken? She hadn't even noticed.

Genos threw her legs to the side aimlessly; she had been so distracted by attacking his arm that he had easily ripped of her legs with his free one. Now she would surely see that he was serious in his intentions.

He glared up at her coldly; this game would soon be over and surely now she knew what she was up against. There was no way she could win against someone like him. She was just a bug after all.

She gasped in awe; he was quick and quite clever to tear off her limbs without her noticing. She huffed crossly and flew away; this wasn't over yet. She still had other parasites elsewhere she could drain power from.

"Futile" Genos stated firmly firing another blast from his hand. She was powerful; but by far the weakest enemy he had ever faced. More mosquito's appeared blocking his attack like a shield. As long as they were under her control she could use them to protect herself.

"You cannot escape from me" he said coldly staring her down like a fish on a cutting board. He would see to it that he put an end to her life before she caused more danger to the city.

The mosquito woman flew above the city towards the forest. This guy was strong; far stronger than most people she had ever encountered. "What is that guy?" she snarled angrily. She had never faced and enemy quite as strong as he was; but she had both her arms to which he did not.

"He'll get me if I don't come up with something" she cried anxiously. She had promised her master she would do him proud; if she let this guy beat her she would let him down.

She smirked wickedly and licked her lips. Things were not over yet; she still had a backup plan up her sleeve; surely with this she would win. "The townspeople may be hiding; but there are plenty of animals to feed on" she leered wickedly.

She had sent her babies to the forests to gather more food to power her. They had devoured every single one of the animals leaving corpses everywhere; that alone would be enough to power her.

The mosquito's left the bodies of the animals they had drained and headed towards their master to feed her starving body. "That's it…" she panted breathlessly excitement filling her body. She couldn't wait to taste every single drop they had to offer.

"Come here little ones…" she gasped hungrily spinning her body around "…Empty every single drop of the delicious juices you carry into me!" she cried flying with her arms wide open.

Within seconds a massive cloud of insects surrounded her filling her with every single drop of blood they had acquired. With this much blood to feed her surely her win would be assured.

Genos rushed forward to witness the cloud forming above him. Just where had she gotten the blood from? How much of it had she now consumed? This didn't look good. Surely now her power would be much more dangerous.

"So many…" he worried mentally. "…If she has been collected blood from the town as well as the surrounding area then it may be more than just a simple food source for her" he stated worriedly.

To be so desperate for blood; it was not a form of satisfying hunger. It was a way of increasing her power; so she could become a stronger enemy in battle. Why hadn't he realized this sooner?

He raised his free arm; the one he could still use to fight. This needed to end now before any more damage was done. "I should put an end to this now; while I still can" he stated firmly. Things were getting more and more dangerous by the second.

If he did nothing, then many lives would be at stake and the danger limit would be raised to the point of evacuation. Many of the people were hiding in their homes outside the city; others had cleared from the current location.

"GET BACK HERE YOU LITTLE SHIT!" An angry female voice screamed. The voice was so surprising Genos was thrown off his concentration. A woman in her early twenties and bald wearing a casual attire was running down the street like a maniac chasing a mosquito with a can of bug spray.

Genos looked at her in concern; why was this woman out here and just what was she trying to achieve? Surely she would die by having her blood drained by being out here. He didn't know whether to call her stupid or brave.

Saitama continued to chase it until she realized she accidentally inhaled it via her mouth. At least now it would be dead even if it was disgusting. "CRAP I SWALLOWED IT!" she cried bitterly trying to spit it out. She managed to spit it out then wiped her mouth with her sleeve.

She then looked up curiously to see a robotic male standing before her. What was he doing out here by himself? She looked up to see a black cloud forming and swirling above her head. Just what the hell was that?

"What's that black orb?" she questioned thoughtfully. It looked like ash or smoke; but neither moved in such a manner. Holy shit it couldn't be; was that large swarm...possibly more bugs?!

"Are those…. mosquitos?!" she cried out in disgust. God today was just not her day! She would need a whole bag of cans to get rid of all of them. She stared up in horror crying out quietly. She hadn't come prepared for this; why didn't she go to the store and buy more?!

"Excuse me miss!" Genos said firmly. This young woman had no idea just what she had gotten herself into; she was in real danger out here. While he admired her courage she was most definitely out of her depth here.

"Hmm?" Saitama said curiously looking at the young robot. He looked like one of those heroes from a TV from her childhood. What was that show called again? Power rangers? Transformers? She forgot.

"Evacuate" he ordered firmly. The city was no longer safe and given this enemy all heroes who could fight the enemy would also be killed. They all carried blood so she could drain them dry and use their blood as power.

"That swarm is conscious" she was only lucky that she hadn't been sensed already. If they did she would certainly be killed on sight. Genos stared at it coldly "And if it senses you it will attack" he warned firmly. She would end up drained dry like that other guy.

Saitama stared at him a look of shock on her face; she thought Mosquito's only drank blood to survive. But these things were taking blood willingly?! "Seriously?" she said in disbelief. What a world they lived in where insects actually became conscious of the world around them.

"That sounds bad; we should…" Saitama started cautiously pointing in the other direction. They should leave before trouble got out of hand. There was no use in staying if there was no way to win.

The mosquito woman laughed manically; nothing could stop her now. She was unbeatable; with this much blood that little tool had no chance against her. She was more powerful than he could ever imagine.

Genos looked to the side as the swarm grew bigger. Her power level had raised higher than before meaning danger was imminent. If this woman stayed her life would surely be at risk; but he couldn't exactly ignore the enemy either.

"Oooh" Saitama called worriedly her voice bland. That didn't look good; that cloud had definitely gotten bigger. Now if only she had a giant can of bug spray to finish it off; that sounded great right now.

Suddenly the cloud dispersed attacking every building in sight breaking windows and causing chaos in his wake. Genos summoned as much fire power as he could manage creating a blast that would take out the entire swarm.

Fire and heat surrounded the town drowning it in a lake of bright orange and luminous light. Everything was burning be it bug or not; hell was being set loose on city Z. Steam and ash surrounded Genos after launching his attack. No more bugs were able to collect any more blood; they had all been incinerated.

The city was now derelict and would need weeks to repair; but at least the city was safe even if it looked like shit. "If she could speak I thought she would at least have human level intelligence; but in the end she was just a bug" Genos said adamantly.

All that talk in the end had amounted to nothing; all bark no bite. Truly beating her had been far too easy. She was quite laughable as an enemy to be taken seriously; he had believed for a second that she was truly a threat.

"Bringing the mosquito's together made for one easy to burn swarm" he said proudly. The area in which the swarm had been was now roasted and burned like a lake of fire.

"When I first spotted her I confirmed that there were no living beings within 5 metres from all directions" he stated firmly. Every human in the city had evacuated long ago or hidden in their homes. Nobody was stupid enough to brave going outside out of fear of being killed.

"This location allowed me to fire at will" he said sternly. He then realized he had forgotten about that one foolish citizen that had dared to go outside. She would have not been able to avoid that blast; she would have been turned to ash because of his own carelessness. Now he had the blood or ashes of a young woman on his hands.

"Wait a second! That young girl would have..." he began to panic. While he had never intended to; he may have just killed someone. He would carry this guilt for the rest of his existence; how would he explain this to Dr Kuseno?

"Daaamn you saved my life there!" Saitama cried in surprise impression in her tone. She thought for a second there she was toast. Her clothes had been turned to ash but she could always change when she got home.

Genos turned and had to process his system not to blush or have an artificial leak from his nose cavity. While he was a robot even he could be affected by the appearance of a healthy and stunning human female.

There amongst the smoke and rubble stood the same woman from before. Only her skin was slightly singed and her clothes were all gone. She had quite sizable bust which were very distracting to look at. Her skin was very smooth and beautiful and her curves were very lovely.

"You could say; you made those bugs bug off" she joked in a cheesy manner. Yes she knew it was a bad pun but she couldn't resist. She had often gotten teased in middle school for her bad jokes.

Genos stared at her in awe and disbelief. While he was thrown by her stunning and delicious body; he was also amazed that she hadn't been killed. Just how had she managed to resist such fire power without being burned alive?

"See that was a joke about the mosquito's being bugs" she explained awkwardly. Did he really not get that joke at all? God that made him even worse than her; talk about awkward.

The smoke cleared to which a stop sign appeared covering her groin giving her some decency. However, Genos didn't know whether or not to tell her he could still see her breasts.

Before they could speak they heard the flitting of wings. They still had this enemy to deal with but Genos was in no state to beat her powered up form; he was damaged to say the least.

She laughed manically at her new power up; she floated before Genos in the air not noticing the young woman who was standing nearby him. "You idiot!" she taunted wickedly. Had he really believed by singing those insects that he had won?!

She floated before him leering at him in new form; she glowed a reddish pink colour with all the blood she had just consumed. "I no longer need my tiny little helpers" she mocked smiling at him. Thanks to all the blood she had consumed she could fight him without fear or being destroyed.

"I mean…" she trailed off her smirk turning into a manic smile. She slashed her claw at a nearby building causing it to explode. With her new found power she had no need for her lackeys anymore.

Genos stared in horror as she destroyed a building with one swipe leaving it nothing but ashes as rubble. Drinking all that blood had made her far more powerful than before. He had no idea if he would even be able to beat her.

"Just look at how strong I've become" She gloated her voice now a roar. While he had been a threat before; he was now just a puny ant in her way. She looked down to face him laughing manically a mad grin of power on her face. She would make him pay for tearing off her limbs like that earlier.

She zoomed down to attack him moving like a bullet now. She appeared behind him so fast he didn't have time to even react. She raised her claws quickly slicing at him with expert precision; her aim caused a massive slice in his torso causing him to be cut almost in half.

Genos groaned in pain as his sensors and system were almost cut clean in half. If she did any more damage to him he would most certainly be destroyed. He lunged a punch at her only for her to send him flying into the air like a ping pong ball. With her current strength he proved no threat to her any longer.

She flew at him as he dropped through the air a pink light surrounding her body. Again and again she attacked him leaving more and more damage to his body as she attacked.

"Can't your macho punches kill a little mosquito?!" she mocked playfully. Its seemed his playtime was over and he was nothing but a weakling now. She laughed manically as she tore more and more pieces off of him. Bits of hard wire and gears falling off him like rain and leaving him to sport a new empty eye socket.

"What a weakling" she growled devilishly as she watched him suffer. Compared to her new strength he was but a toy soldier with some advancements. Guess he really wasn't as tough as he made out to be.

Genos felt gravity pulling him towards earth slowly; the realization of the impact of the situation now hitting him. He had truly misunderstood the entire situation and was out of his depth.

"I get it now; the more blood she is able to consume, the more powerful she becomes" he realized horrifically. With the amount of blood, she had now consumed; she was unbeatable in his current position.

She floated in air quietly watching him suffer; this had been drawn on long enough. Now it was time for him to die. "I think I'll have your head next!" she roared her playful tone slowly becoming psychotic. She would show him not to mess with a power far stronger than his own.

Genos fell towards the earth faster and faster his strength slowly leaving him. He was dead any minute now; she would be able to beat him easily like this. "I let my guard down; I have no chance of winning" he realized dauntingly. His core glowed a bright blue; exposed and able to him to be destroyed.

"All I can do is self-destruct" he stated firmly. He had tried his best to serve his mission but sadly he had no chance of winning against her; he was just not strong enough. He had done his best but sadly it had not been enough.

"Forgive me doctor" he apologized sadly as Mosquito girl drew in for the kill. This way he could kill her and himself ending it all. He would save the city at the cost of his life; but he had committed a good deed doing so.

Mosquito girl laughed manically as he went in for the kill. Nothing could stop her now and her master would be so pleased. Suddenly she was met by a hand to the face sending her flying. Before she could think she was killed instantly by being thrown into the corner of a building. Blood she had just devoured lay splattered in the corner.

Genos gasped in shock as he saw the enemy which had been nearly impossible for him to take down; crushed in an instant by this random woman. Just what in the hell was she?!

Saitama smiled proudly at her defeat; finally, she would no longer be bothered by that buzzing pest. "Bugs….really are annoying" she stated proudly smiling at her win. Now she wouldn't have to worry about annoying buzzing in her ear.

Genos landed on the floor in a heap with a loud thump. He groaned in pain at the contact of hitting the ground; he was in desperate need of repairs. However that could wait; he hasd to know the secret behind this woman's strength.

Saitama content with her actions walked away quietly. The enemy was defeated and she could now go home and get dressed; maybe go to the store later. She still had some things to pick up; plus egg topped hamburger with cheese sounded good.

Genos watched her leave in horror "WAIT A MINUTE!" he yelled desperately. Who was this woman? How was she so strong? What was her name? He had to repay her for what she had done.

"Hmm?" Saitama questioned curiously. Oh yeah this guy probably needed to go to repairs; he was pretty bashed up. She had meant to act sooner but the bug hadn't really noticed her and had attacked him before she could act.

"Please! Tell me your name!" Genos begged desperately. He owed this woman his life; he had to make it up to her. No matter what it was, no matter what she asked him; he would do it for her.

"Oh…" Saitama said casually; he probably wanted to thank her for what she did. It was no big deal she was just getting rid of a pest. "…Its Saitama" she said casually. The kanji for Sai meant "Greatest/most" and Tama translated to "Soul" so her name literally meant greatest soul.

"I would like to be your disciple!" Genos begged quickly. Surely under her teaching he could become stronger than anyone. He could be able to destroy enemies he stood against as easily as she could.

"…Um sure" Saitama said casually starting to walk away before she realized what he had just said. Did he just say he wanted to train under her? But why?! "Wait? What?!" she said in realization. All of a sudden this guy she saved; wanted to be her student?!
