Chappie 1

AN:This is my first fic so flame me or criticise me, all is welcome as long as you make a point on why it was good/bad. I got the inspiration for this when Blizzard referred Saitama as 'monstrous'.

Disclaimer, I do not own One punch man, all credit goes to ONE and Yusuke Murata.

Summary: AU where Genos was already a HA member and Saitama trained so much he became a monster.

He had always wanted to be a hero, the ones featured on TV where they swooped in and saved the day. And so, he trained, he trained until he could not anymore, until his body has failed him and he for some time ceased to exist. His name was Saitama, the most bored spirit alive. Or dead if thats how you want to view it. Saitama wanted to believe that he was still alive but lying to himself won't solve anything, how can you call yourself a living being when you need no sleep, food, water and lacks the appropriate emotions to be human? Saitama believed himself to be a spirit now, something non human, or a 'monster' as the media would term it. The new body made purely of energy did have its perks however as Saitama has gained incredible strength, so much so that he stopped feeling the thrill of the fight, or the motivation to seek it. It made him feel sick at times where he would question the reason for his existence late at night where he wished for some of his human characteristics to come back to him. Like the need to sleep or the desire to eat. Like c'mon! Udon was his favourite food but now he can't eat it!

Saitama sat on his bed for some time before signing and trudging to the mirror, where he viewed himself for the 30th time that day, looking for any changes that he might turn back into a human again. But to no avail, he still looked the same, a humanoid manifestation of pale blue energy, swirling with anger, contrasting his emotions. He hesitated for a moment before donning his disguise, an old black hoodie, a dog mask and some loose pants before floating through his doorway and onto the abandoned streets of the 'ghost' town abandoned because some dumb 'monster' was roaming there. Saitama was determined to at least make it to the nearest 24 hour convenience store to get some new comics. It still seemed strange to Saitama how his body reacted to its environment. His body is physically tangible but still made up of energy that seemed indestructible, he shrugged and let the matter rest, knowing that he would probably never know the answer. Shoving the door aside, he disappeared into the dark streets.

…"incinerate!" Saitama looked up surprised at what seemed to be a blond guy on the roof battling it out with a bug looking lady. They were exchanging blows, yet neither seemed to be superior, a fist for a horn and a claw for a fiery blast.

"Ugh, Can't believe people these guys, fighting at this ungodly hour, at least do it in the afternoon where you won't wake anyone up!."

"Incinerate!" The annoying blond guy yelled again before unleashing a much bigger blast of heat that even Saitama felt slightly, the mosquito lady flinched before she launched her own attack, ordering the nearby blood suckers to converge on the cyborg's position. Saitama paused, wondering about the thought of intervening, after all they were fighting awfully close to his run-down apartment. 'Ehh whatever, I'm sure they can figure it out'.

"Hey you! Get out of here!" The cyborg finally noticed Saitama, confused as why his life sign scanner didn't pick up this guy before he started fighting.

"Me?"

"Yes you, please evacuate now, I am currently engaging a monster, it is very inconvenient to look out for a civilian right now,"

"Oh ok," Saitama retreated, worrying for the safety of his last pair of shoes and mask.

"Not so fast! Puny human! I need your blood! Buahahahaha!" The mosquito lady laughed psychopathically and dove for Saitama, her claws drawn, ready to meet flesh. Clang! Mosquito girl looked on in disbelief as her claws only cut into the fabric of the man's clothes but shattered against his flesh. 'How strange, he resisted my attack and didn't even flinch! Come to speak of it, he is wearing a mask, is he even a he? A Human even? Her eyes suddenly widened in shock.

"You're a monster!" She screamed, "How exciting! Look at your body! Why are the colours swirling like that!"

Saitama froze, uncomfortable in this awkward new situation he found himself in.

"Another Monster! How? I should have known to not be rash and fight in the ghost town. Tsk, looks like I would need to call for backup," The cyborg said to himself before blasting the two figures, throwing a smoke detonator and rushing for cover.

"Oh, the annoying pest has gone! Nice! Now I can compare my strength against yours monster man!"

"Hey! Im not a monster!" Saitama exclaimed indignantly,

"Yeah and I don't have wings" The bug lady flexed her wings and looked at Saitama, "You don't look too strong but you resisted my blood slash, you've got some nerve to not flinch,"

"Nah it was just pretty weak,"

"What! Y-You Ahhhggg, how dare you insult the pinnacle of artificial evolution! I will tear you apart and suck out your blood!"

"You talk too much, you know that?" Saitama casually said and slapped, no eradicated Mosquito girl, the mighty sound echoing through the dark night. Saitama looked around before shrugging and returned to his apartment, after all there was no point in going back out in public after your monstrous physique is on display for the world to see and the heroes to trigger.

Meanwhile a pair of wide golden orbs stared in shock at the retreating back of the 'man', a whirring sound indicating the presence of a recording device. " I've got to get this back to Dr, Kuseno and the Hero organisation, I have found the mysterious monster of City Z!"

The next day, Saitama was reading his precious collection of manga before a particular announcement on the TV made him freeze in shock. "BREAKING NEWS! The mysterious monster of city Z has been sighted in action by non other then the class S hero Genos!, Genos, what happened last night?"

"I was engaging a demon level threat monster before it showed up, it was humanoid, it had a dog mask and wore civilian clothing, showing the ability of moderate intelligence through speech. It also eradicated that demon level monster that I was fighting in just one hit. I am now currently unaware of its location." A terrified expression was plastered onto the host's face,

"You mean you didn't defeat it?"

"No. It was too strong, I needed to assess it and carefully plan my next actions before I engage it. A kill bounty has been placed on him by the Hero association, offering 8 million for the confirmation of the kill or capture of the monster. Here watch this clip my camera captured," Saitama looked on in growing horror as a grainy video showed him slap the monster, but the true horrifying detail was that the video captured his apartment in the background! With the light still on!

"Be careful my comrades this monster is at least a demon level threat! Please form a hero squad with at least 3 A-class heroes before engaging!"

Saitama sweat dropped. Now he he has to move houses again.
