Author's note: hello, I just wanted to clarify that this story has a similar premise to a certain arc in the show, unintentionally. I wrote this when the SeaKing arc started and it took until now to finish it due life bombarding me with things I have to do such as exams and what not. So I had absolutely no idea that I was writing something exceedingly similar to a certain arc in the show, I just followed the basic formula that is used during a fight scene in one punch man and lengthen it. Anyway that be all, don't forget to review.
The Challenger
In the Z city ghost town a mysterious hooded man is seen walking through the streets, seemingly in search of something. The ghost town is an extremely dangerous place that has become over run with Monsters. Any sane man would turn tail and leave but he seemed to be casually strolling along and ignoring the numerous warning signs plastered all over the area. As he was walking he abruptly stopped and said: "Damn, what street does he live on again?" He then took a looked at a piece of paper that had an address on it. As he kept walking, numerous piles of dead monsters can be seen scattered all over the road behind him, along with the complete devastation of large buildings and overpasses. The absolute destruction looked as if it was caused by a category 5 hurricane.
After a few more minutes of walking he finally came across Saitama's apartment building.
"So this is where he lives?" He said confused.
"Honestly I was expecting a castle." The mysterious stranger remarked right before he made his way up into the building.
The mysterious man eventually made it to Saitama's front door and proceeded to knock on it. Inside the apartment Saitama was in his pajamas and watching tv when he heard the knocking. He then told Genos to answer the door.
"They Genos could you get that?" Saitama said, however, Genos didn't reply because at this time he was busy cleaning the bathroom.
The knocks got more and more persistent and Saitama eventually decided to see who was bothering him so early in the morning.
Saitama then opened the door and said: "What do you want?" addressing the person in front of him in an uninterested tone.
The mysterious man then pulled down his hood to reveal that he was of Greek decent he appeared to be in his mid thirties. The man had blood red hair, a short beard, brown eyes, a muscular athletic build and was wearing a grey sleeveless hoody, black jeans, and combat boots. He was also carrying a gym bag on his right shoulder
"Good morning, Im looking for a Mr. Saitama, Is he around?" The man said.
"I am Saitama."
"Oh? Well allow me to introduce myself my name is Atlas and I've journeyed across many….." At this time Saitama wasn't really paying Atlas much, he was instead concerned about what to eat for lunch when suddenly he spots Atlas's gym bag.
"Oh no, this is one of those guys who goes door to door selling useless crap isn't it? The kind of people who will never leave you alone unless you buy their stuff. I got to get rid of this guy!" Saitama distressingly thought to himself. Saitama then cut him off by putting his hand in front of Atlas.
"Look whatever it is your selling I'm not interested." Saitama said right before he closed the door.
"Well that was rude, he didn't even let me finish." Atlas said with a baffled expression.
"Guess we'll have to do this the old fashion way." Atlas stated, He then proceeds to cock back his left arm.
On the other side of the door a relieved Saitama turns around and starts heading for his TV when suddenly he senses something.
At that moment Atlas threw a punch right through the door! However, Saitama was able to intercept it with ease. Saitama stopping Atlas's punch in midflight resulted in a massive shockwave that blew apart the other half of the apartment building along with the other buildings across the street.
Suddenly Genos comes out of the bathroom with both his arms locked, loaded, and aimed at Atlas!
"Saitama sensei! Who is this man? Is he a threat because I will incinerate him!" Genos said. Saitama didn't reply instead he was looking down at the ground and processing what had happened.
"WHAT THE HELL YOU JERK! You blew up half of my apartment! You better pay for it! Saitama yelled enraged."
"Well you started it, I mean closing a door on someone before they finished talking was very rude you know. '' Atlas retorted.
"Oh, well if you put it that way then I guess I am to blame. I just thought you were one of those door to door salesmen, my bad" Saitama said after realizing his error.
Atlas then took a look at the damage he caused and said: "Don't worry about the damage il cover it, consider this a down payment." He then took a large wad of cash out of his gym bag.
"So what was the reason you were looking for me?" Saitama asked
"Since you apparently don't like long descriptions il keep it short. My name is Atlas and my dream is to become the strongest in all existence, it just so happens that you're standing in my way. In other words IM HERE TO CHALLENGE YOU TO A FIGHT!" Atlas explained.
Shocked at what he had heard Genos thinks to himself: "Challenge master to a fight? This individual must be capable of extraordinary feats if he thinks he can stand against Saitama sensei."
