I am relatively new to this so I am open to making some changes. Due to the fact the manga has a small cast of female characters I decided to make Speed-o'-Sound Sonic female (if this is unpopular I can easily change it back and this was the only gender change I planned on making in the whole story.) In addition I didn't know where I should refer to Saitama as Faceless or if I should do it at all. Any criticism would be appreciated even if it doesn't offer any advice. Let me know if I'm doing a bad job at representing any of the characters.

Chapter 2

Battles of Z City

A man with oddly striped eyebrows and hair could be seen walking next to a similarly built, but more normal looking man. These men were Tank Top Tiger, C-rank thirteen, and Tank Top Black Hole, B-rank eighty-one.

Tank Top Tiger snorted in frustration "Man, why were we called out to this dump of a city. I've always disliked city Z. Nothing is here except for empty buildings and boredom."

"Look bro. We got called out here because of reports of excessive pollution and a disturbance in the environment. It's probably nothing and if it is something it's probably just a low class monster," replied Tank Top Black Hole.

"Tch…yet another enemy who won't be able to stand up to the amazing power of my physique and tank top."

As soon as Tank Top Tiger finished his statement an explosion ripped through the city several blocks away. Shards of shredded metal and broken glass rained down upon the streets as screams began to resonate throughout the city. An ominous purple haze appeared over the tops of the buildings as a creature began to emerge from the fog. The monster had a chiseled purple body with muscles that were constantly fluctuating with the creature's heartbeat. The top of his head was adorned with two bug like antennae. "I AM VACCINE KING! PREPARE TO BE DEMOLISHED!" the abomination shouted out to the heavens.

Tank Top Tiger's eyes widened a fraction. "Hey brother….I'm not saying I can't take this thing on, but I thought this was supposed to be a wolf level threat. This thing is at least a tiger threat. I mean, it just destroyed several buildings."

An arrogant appearance covered Tank Top Black Hole's face. "Don't worry man, if we work together our combined strength as brothers will be no match for this Vaccine Man"

As they began walking towards the monster that had not taken notice of them yet, a sound of wrenching metal and concrete could be heard from behind them. The brothers turned to see a cape and cloak fluttering in the wind. They both had the same thought, 'What the hell is Faceless doing here?'

Earlier in the day:

Saitama was in quite the bad mood. He had had another rough day at work and had found out almost no useful information about heroes or what the Association knew about him. 'Well I might as well get some dinner somewhere. Maybe I should try city Z. I'll have a high chance of running into a monster there as well.'

As he arrived in City Z he began searching for a restaurant. Eventually he settled on a restaurant that he visited regularly. As his waitress approached the table he noticed that he had not seen her here before. She had grey eyes and her dark hair was pulled up into a topknot. Purple markings adorned her face directly underneath her eyes. Oddly enough, she had the appearance and awareness of an experienced fighter. 'It could just be that I'm overanalyzing the situation,' thought Saitama.

"Hello may I take your order sir"

"Hmm I think I will have the katsudon this time please"

The waitress's eyes widened. 'T-this tone of voice. As a ninja I have been trained throughout my life to notice the most subtle details. Although his voice sounds nonchalant I can tell it also radiates with power. His body language says that he has no fear of his surroundings….this is a man who I must fight. Regardless, I doubt he is any match for my speed.' She quickly finished taking his order and retreated back to the kitchen area of the restaurant. 'Damn, out of all the times to not bring my weapons with me. Oh well, I have already decided I will follow him after he is done here.'

Saitama obliviously finished up his meal and left a somewhat generous tip. Suddenly, sounds of destruction could be heard throughout the city. Saitama furrowed his brow in annoyance 'Ugh, Im not in my costume right now. I guess I can just use the bathroom in the restaurant.' He rushed into the bathroom where he quickly began to change into his costume.

Speed-o'-Sound Sonic had easily noticed the mood change on Saitama's face when he rushed to the bathroom. 'Hmm…it appears as if this man is going to take action based on his reaction to those explosions. His presence has changed. He feels more dominating and there's a part to him that I can't read as well'

At that moment a resounding crash could be heard from within the bathroom. From inside came a reply. "Hehe sorry I have really bad stomach pains today."

Speed-o'-Sound Sonic sweatdropped and continued waiting outside of the restroom. After a few minutes of listening to the sounds of running water her patience had ran out and she decided she valued fighting this man more than her crappy job. She crashed through the restroom door only to find no one in the restroom. The entire back half of the restaurant was entirely gone. The toilet was shattered into porcelain bits and a small geyser of water was rebounding off of the ceiling and flooding the floor. 'God dammit' Sonic thought as she dashed outside of the building. She didn't know exactly where the man was, but she had a feeling that he would be somewhere near where the explosions occurred. She jumped off the sides of the buildings as she began to search for the most destroyed section of the city.

In front of Saitama there were two muscled men wearing a weird shirt style. Beyond them he could faintly see the figure that was most likely behind the damage caused to the city. Luck would have it that he would run into heroes from the Association. They weren't even strong and would hardly provide even an ounce of entertainment. 'I suppose it really doesn't matter if they see me now. I've already been identified by the Association. The least I can do is show them a glimpse of my power so that they will send only high class Heroes after me. Besides, I sort of need to take care of the purple guy over there. I will need to hold back greatly if I don't want to injure them too badly…no punches it is then I guess.'

The brother with the striped hair spoke up. "Haha you sure picked a bad time to show up. Together with my brother, I will demolish you. You are only a low Tiger ranked threat and both of us can easily take care of something at that level."

Saitama stared at him with a blank face and his facial expression failed to change at all. The B and C class heroes couldn't see his face, but they could tell that he had no reaction to their words at all.

"Hey! What do you think you're doing acting all cocky like that? My bro and I will show you your true place!" declared the dark haired brother.

Tank Top tiger rushed forward as his brother began circling around to the other side of Faceless. He threw a punch directly towards Saitama's head, but found it passing through thin air. Tank Top Tiger froze in shock, "W-where the hell did he go?"

"Right here!" Tank Top Tiger turned around only to be met by the arm of Faceless. The arm clotheslined Tiger and he flew into the side of a parked car. Tank Top Black Hole could feel a gust of wind as he watched his brother fly into the car, bending it in half and instantly getting knocked out in the process.

His mouth dropped open in surprise, but he quickly recovered. "Y-You think I'm falling for that. There's no way my bro was taken down that easily. I bet that it was just a fluke. It's time for you to pay for what you have done you criminal!" Black Hole bull rushed the cloaked man and attempted to punch him. He quickly found that his fist was entrapped in an iron grip and despite his struggles he could not free himself. With his other armed trapped, he decided his only option was to throw a punch with his other hand. His fist slammed down upon the face of his enemy and the snapping of bones could be heard. "GAHHHH!" he screamed as he pulled back his fist in pain. The bones in his hand were completely shattered and Faceless had not moved an inch. He came to the realization of how utterly outclassed he was.

"W-wait I'm sorry I didn't mean anything I said earlier. I promise we will—." Black Holes sentence was cut off as Faceless reared back his fist and shot it sideways a bit in front of his face. A sonic boom erupted from the fist and a shockwave blasted Black Hole backwards next to his brother. 'H-how….with only one punch….he destroyed me.' were the last thoughts he had before he slumped down next to the car. He was still conscious, but in his state he could hardly move.

Saitama muttered a sentence under his breath. "Damn…one punch again. And I didn't even actually punch them to defeat them." 'Well at least I was able to leave them in a non- critical state. With modern medicine they should be back up and at it in less than a week.' He glanced over at the portion of the city that the purple abomination had been present in. "Fuck" A large portion of the city was now missing. In the short amount of time it took to dispatch the two brothers the creature had fired some sort of beam like attack creating a massive clearing in the middle of the city. The monster was currently standing at the center of the clearing and glanced over at Saitama as he entered the clearing.

Saitama made a massive leap over to the monster and landed in front of it. "GREETINGS I AM VACCINE MAN! ARE YOU READY TO PERISH BY YOUR OWN CREATION?"

Saitama calmly looked up at the creature. "Sure, can we just get this over with? My show is having its finale premiere tonight and I would prefer if I didn't miss it."

"HOW DARE YOU! YOU MOCK WHAT THE HUMAN RACE HAS SOWN! I WILL SHOW YOU THE TRUE POWER OF POLLUTION AND WILL PRESENT THE CURE FOR NATURE; THE EXTERMINATION OF MANKIND!"

Spikes began to jut off of the creature as they pierced through its skin. Slime and chunks of old skin ripped off of Vaccine Man as his muscles bulged and he became even more grotesque. His teeth extended and giant tusk like protrusions appeared on his face. He grew giant claws on his hands and released a massive explosion that rocked the clearing. The smell of chemicals and decay began to fill the surrounding city.

Tank Top Black Hole raised his head slightly and glanced across the clearing to see the cloaked man and Vaccine Man face off with each other. The power that Vaccine Man had begun to emit made him quite nervous. 'T-this monster….he is at least a Demon class if not more. Heh… looks like Faceless is done for'

As he finished his transformation Vaccine Man began to boast about his extreme power to Saitama. "THIS IS THE POWER OF POLLUTION! I AM THE STRONGEST AND AM UNBEATABLE! YOU ARE A MERE ANT, AN INSECT, A SPECK OF DUST THAT I-GLCKKK"

Vaccine Man's statement was quickly cut off. Where Saitama had been standing before was a massive crater and his fist was currently buried in the gut of the purple creature. Saitama slid the rest of his weight underneath the creature and began to extend his fist into an uppercut. Dirt and small particles lifted off the ground as he extended his fist upwards. Vaccine man was instantly obliterated and large portions of flesh and concrete blasted into the atmosphere above. A circular opening appeared in the clouds above where the force of his punch penetrated into the stratosphere.

Tank Top Black Hole could only drop his jaw in amazement at the power that was just displayed. 'This man is surely above a Tiger threat. He just demolished a Demon level like it was nothing. If he was a hero he would undoubtedly be an S class hero.' It was at this point that the resounding shockwave from the uppercut hit him and he blacked out.

Saitama looked upwards with the blank expression he had maintained throughout the fight. Although his face was concealed by his hood, he didn't actually have anything covering his face so it was now coated in a thin layer of blood. "NOOOOOOOOOO NOT ANOTHER MONSTER THAT DIES WITH ONE PUNCH AGAIN," he wailed in disappointment. He proceeded to wipe the fluids off his face and trudged to the end of the clearing.

As Saitama began to leave the city he heard a voice call out. "Wait right there! I'm going to assume you are finished dealing with whatever was causing those explosions so I can only assume you are a decent opponent. I Speed-o'-Sound Sonic will defeat you! You'd better provide a good fight."

Saitama turned around to see a familiar looking face. "Waitress-San?"

"W-what no! That's just my day job; right now I'm a ninja and I will prove to you that I am the fastest being alive," sputtered Speed-o'-Sound Sonic as she pushed off the building she was standing on and began to attack Saitama. She picked up several shards of metal that she had found on the ground and threw them as if they were throwing darts. Cones of air formed around the shards as they raced toward her adversary, but they quickly phased through his image. 'W-what the hell…what kind of power does this guy have' she thought, as she retreated back to a longer range.

Saitama turned to face her. "Are you done or am I actually going to have to fight you?"

Enraged at the comment made by this stranger, Speed-o'-Sound Sonic began to bounce of adjacent buildings, incrementing her speed every time she touched down on one of them. Vapor trails began to drift of her arms and she angled herself to face her opponent. She unsheathed one of the metal bars she had picked up previously and swung it at Saitama only for it to phase through him again. 'How the hell am I supposed to defeat someone whose power is to make themselves intangible to attacks? Maybe if I attack him where he can't see it will work.'

She backed off to a further location where she could view the whole battlefield and chucked her bar behind Saitama and then acted like she was disappointed that she missed. She then threw some more metal shards at him that phased through him. As the metal bar rebounded off the building behind Saitama she stepped back to view the whole battlefield. The metal bar approached the backside of Saitama and right before it hit him a flash of black appeared on the other side of the street before disappearing. Speed-o'-Sound Sonic took a step back in disbelief. 'I-it's not that he's untouchable. I'm just too slow. How can someone be so fast that I can't even see them?'

Saitama huffed in annoyance 'Honestly, three fights today and none of them are even slightly entertaining. I don't really want to hurt Waitress-san, but she is too fast for me to accurately aim a punch that won't injure her. I guess I'll have to go for one of my wide scale attacks then.'

Speed-o'-Sonics face scrunched up in confusion as Saitama reared back his fist even though he was on the opposite side of the street.

"Consecutive Air Punch Cannon-Jab Mode" stated Saitama as he slightly drew back his fist and made multiple punches in the frame of a second. Each punch only required him to draw his fist back a few inches and then shoot it forward, but the effect was devastating. The whole area that Speed-o'-Sound Sonic was standing on was instantly flattened with a pressurized blast of air and the surrounding buildings and cars were crushed. She was pressed against the building as the force started to increase and began to slowly lose her vision.

As Saitama began to leave the city a faint voice could be heard nearby a crushed car. "Hello, Tank Top brothers reporting in. We have some info for the Association."
