Hi everyone, I'm new to all this fanfiction stuff, so I wanted to say hi
That was a small message for all the new ones who read this story, for the old ones I want to tell you that it is a pleasure that you still read my story
I will start with something simple to say, I am changing chapters 1 and 2 with the help of a new friend I made: Transcended Potato
He offered to help me rewrite the first 2 chapters and continue with the story itself, only I will be writing the chapters and he will only review them and tell me if he needs correction in something and help me correct it
A special thanks to him who is undoubtedly helping me with this story and in return I am helping him with his current story
Without further ado, let's begin!
[A year before the series starts...]
Under the cover of the blackness of night, a man is walking back to his home. He was a tall, large man with slightly tanned skin, blue eyes and straight blond hair that kept his hair up to his shoulders which also combed his neck. His notorious features were three vertical scars directly on his left eye, with sunken cheeks and a defined jaw line. He wore a black turtleneck sweater with long sleeves.
This man was King, an ordinary human that was recently designated with the title of S-Class and aside from his hero name of King, he even had countless titles for his 'monstrous strength', such as The World's Strongest Hero, Hero of Heroes, and The Strongest Man on Earth. Normally this would be cause for celebration but it wasn't for him.
At that moment, he was touching the scar in his eye and reminiscing on how he got it.
[2 years before...]
A younger king was nearly jumping for joy because the sequel of his favorite game had just released today and he managed to buy it.
"Sigh... Today was a good day, a remaster of the original Doki Doki Sisters was released today and I managed to get a special copy of the game, nothing could possibly ruin my day today!" He said to himself, without realizing he jinxed himself.
Before he can realized what was happening, a tentacled monster appeared out of nowhere and started destroying the surroundings. The worst part? It was a famous monster that left close to no survivors whenever it appeared. Octoclaw Man.
He fell to the ground, too scared to do something and before he could even move, a clawed tentacle was shot towards him. Sheer instincts taking over, he only managed to barely dodge, which made it hit his eye instead, causing three wounds on his left eye.
"GYAHHHHHHH! MY EYE!"
He grabbed his eye in pain, falling to the ground.
"AHHHHHHH! S-SOMEONE HELP MEEEEEEE!" King screamed for help, his eyes closed in pain. Though he screamed for help, inwardly, he expected nothing. The monster appeared out of nowhere, the chances of a hero appearing to save the day was slim! Slimmer than the chances of another release of Doki-Doki Sisters before the end of the month!
Yet instead of death, King heard silence, and then there were loud crashing sounds, and the sound of a fight. And before he even registered that, a loud 'pow' was heard, and then the sounds of fighting stopped.
Then, and only then did he realize, a hero saved him! Thanking his lucky stars, he made a note to write a letter to the hero that saved him! But who could be the hero that saved him, the hero association was created recently, who could have saved him?
"Hey, calm down." Suddenly, an unfamiliar voice was heard. That wasn't the voice of any pro hero he knew...
"I beat the monster. Is your eye okay?" He heard the hero ask. "The cut isn't that deep. Try opening it."
Following the hero's instruction, King slowly opened his eyes, and both his eyes could see! He expected to have been blind in one eye after this, even if he did survive. What hand of luck pulled him to not only survive this monster attack, but keep both eyes, no less!?
"W-who are you?" King asked, as the voice was not of any hero he recognized. Turning to his savior, he saw not one of the heroes of the Heroes Association dressed in their flashy costumes, but instead...
"Me? Um... I wanna be a hero for fun." He said. "If a hero arises, it'll probably be me." It was an ordinary looking man. Wearing a blue tracksuit, he didn't even look like a hero in the first place! Hell, he looked like an ordinary civilian! But looking closer, that wasn't the only thing.
"You're hurt!" King said to his savior. He had gotten scratched once over his left eye and screamed his pants off- this man was basically wounded all over!
"These are mere scratches." His savior said, as if the wounds on his body were nothing at all.
"Ha ha! Today was a great victory!" The man said happily, walking off before King could say anything.
[End of flashback...]
That was the only time he ever saw that man. He was so shocked by him beating the monster he couldn't even properly thank him, and even after he got back up, he tried to find him, but to no avail. The Hero Registry didn't have someone like him. Chances were that he was what they called an 'Unregistered Hero', vigilantes that didn't register with the Heroes Association, and did hero work on their own.
They said that they were nothing more than just costumed weirdos, yet King knew better. That man, that 'Unregistered Hero' was the one that saved him!
After that, his luck was got worse and worse, he continued to encounter monsters and always ran away before someone else defeated the monster and he was the one that got the credit for killing the monster.
He tried to tell somebody, anybody that he wasn't the one that killed the monster, but his cowardice always got the better of him, and the simply remained silent on the matter.
And today was the culmination of all the unearned credit he got. An S-Class certificate.
He didn't really want to be a Hero but the money was nice... Still, he couldn't muster the courage to tell them that they had picked the wrong person to promote as an S-Class Hero. Time and time again he mustered the courage to try and tell them, yet every time he stepped out of his apartment, his determination fell apart like a poorly-built Gundam model, barely standing for three minutes before collapsing into an inordinate mess.
But when he got into his apartment after moving from his parents' house, he noticed a new figure in the obscurity of the night in the middle of his apartment and he panicked.
"H-hey, look, I don't want any trouble, okay?" He stammered while trying to turn on the light "I-I didn't want the title of 'The World's Strongest Man', nor did I want to be an S-Class hero, alright?" King said, assuming that this was someone that was unsatisfied about him being an S-Class Hero. "We don't need to fight at all, how about we discuss this amicably?"
Before he could pass out from hear, the lights suddenly turned on, and what- or rather who he saw shocked him.
"Hahahahaha! Ah, I was that coward, wasn't I? Sure takes me back." That person laughed boisterously, yet King could not believe his eyes. This man in his apartment, the one laughing at his cowardice was...
Himself.
"What!?" King said, confused. He was very clearly himself, he could feel himself there, yet for some reason, there was a complete mirror image of himself, standing in front of him right there!
Now that he took a closer look, that person didn't look exactly like himself... he looked a little bit older, his hair seemed longer and he was more well-built. Unlike his current self where he just had a large frame, this person, or rather himself, had proper muscles to his body.
"Yeah, I know, nice to meet you, or well, myself." He said, snickering. "To be honest, I'm still not quite used to this." He said, raising a hand to shake hands.
"Um, nice to meet you?" King said, shaking hands with the person that seemed to be himself.
"Right, right. Now with the pleasantries out of the way, let's get down to business." The older, more mature King said with a serious face that intimidated the younger King. If he didn't know that this person was himself, he'd say that he was rather intimidating. Now he knew why the Heroes Association would assume that he was the one to defeat the monsters around him.
"I'll explain this briefly. The future world's fate is completely dependent on you right now. If you do nothing and let events happen as they should, billions will die." The older King said, already making tea for himself.
The younger King, being the person that he is, did the only logical thing to do.
Panic.
"What!? No! That's not possible! I'm just a normal person, how can I save the world!? No, no, no, no, no! I don't wanna die! I'm too young! I haven't even played all the games I wanted yet!" The younger King panicked after learning this from the older King.
"Hahahaha! I could not have arrived sooner, it seems." The older King laughed, as he calmed the younger King down. And by 'calm', the older King slapped the younger King back to reality. It didn't have a lot of strength, but it was quite a sharp pain.
"Calm down, that's only if you do nothing. But I'm here for that reason." The older King said calmly, sipping the tea. "Hmm, it's more bitter than I expected. Maybe too much tea powder?"
"But how am I going to stop the apocalypse from happening? I'm just a weak, useless ordinary human that has never even fought before." King said, demoralized. It was true, despite his large frame and intimidating face, he never fought anyone before, much less be strong enough to be considered a hero!
"Hmph. Let me ask you something, then." The older King said suddenly.
"Have you never wanted to be the hero in legends, the one they speak of so much?"
"Have you never heard your fans cheers, and thought to yourself, 'I want to become like that man in the stories'?"
"Have you never once thought about making those false stories true? To be a superhuman that saves humanity from peril?"
"Have you never... not once..."
"Thought of becoming strong?"
The words the older King said woke up the younger King, as he realized that he indeed wanted to become that strong person that everyone thought him to be. Even though he loathed his title, sometimes, he would daydream that he was that incredible superhuman that saved the day from monsters. To say that he never thought about becoming strong... was an utter lie that wouldn't fool a two-year old child.
Who wouldn't dream about becoming stronger?
But as his spirit rose, it was just as quickly dampened by the realization that he was an ordinary human.
"I know what you're thinking." The older King said. "But in the future, I, and I mean you, gained a power that made you worthy of that title. At that moment, you truly became 'The World's Strongest Man'. A power so strong and invincible that had you unlocked it earlier, Saitama-bro would still be with me."
The younger King was amazed at the new information, but he noticed an unfamiliar name.
"Who's Saitama?"
"Hmm... how long has it been since you were awarded the S-Class title?" The older King asked.
"Just this afternoon. I just only went to the Heroes Association headquarters to get my photo taken." The younger King said.
"I see, so you haven't met him, I suppose." The older King said. "Saitama is the person that saved you from that octopus monster. We met him sometime in the future, a year later, if I'm not mistaken."
"I-I see... but then how did he die?" The younger King asked.
"Hmph." The older King's originally calm face then turned into a scowl that scared the younger King. "Because of that damned self-proclaimed 'God'."
{Narration by King (Older)...}
It all started with the kidnapping of the son of some Heroes Association executive. We, the S-Class Heroes were supposed to rescue the boy from some Monster's Association. It was going well, and even though I was there, I was lucky I didn't get killed by some random monster. In fact, it was all going so well... too well.
The Monster's Association even had many Dragon-level threat monsters that gave even the top heroes a run for their money. I could list down a few for your future reference.
Homeless Emperor, reported by Zombieman to be a regular human that claimed to have been bestowed power by an entity known as 'God'. After his defeat, Homeless Emperor suddenly died, having his power taken away by said entity.
Black Sperm, a splitting being that contained a vast number of cells in its body that can act as extra lives for itself, and can shape-shift into different shapes with it's additional cell copies. It can even merge into superior forms. The time I faced it, it claimed to have over 11 trillion cells in its body.
Elder Centipede, a massive centipede-like entity. It was almost defeated by Blast sometime in the past and joined only to defeat Blast. The only advantage it has is just it's massive size and hard carapace. It was no problem for Saitama, though.
Phoenix Man. According to Child Emperor, had he not defeated it, it might've been the biggest threat. It can resurrect and gain more power as it 'dies' and 'rebirths'. The only way Child Emperor defeated it was when he tricked it into ripping its costume, the source of its power, and then killing it when it was powerless.
Psykos, a human psychic that was almost comparable to Tatsumaki, though it was after she drank an ESP-enhancing drink. But even in her normal state, she is a rather powerful psychic that can outclass other psychics like Tatsumaki's little sister, Fubuki.
And then, the reputed 'Monster King', Orochi. I don't know its capabilities for myself, only that it could breathe fire and shoot lasers from its mouth. Saitama managed to punch it into pieces, but it regenerated and then fused with Psykos, tremendously increasing the latter's psychic powers.
And even with all that, there was a threat that we didn't even think would appear on that day.
Garou, the Human Monster. He was a martial arts prodigy that was formerly the top disciple under Silver Fang, and during the battle with the Monster's Association, he somehow managed to mutate, becoming a monster in the process. He was strong, so monstrously strong that he wiped the floor with all the S-Class heroes on scene. Only after Saitama showed up was he defeated.
After that event, some S-Class heroes like Child Emperor, Metal Bat and Superalloy Darkshine retired from the Heroes Association and joined a new group afterwards. The Heroes Association might've even been overthrown... had the God-Level threat not appeared.
The entity was a being that proclaimed itself to be 'God', and he came down to Earth with his grotesque 'angels' after claiming that his 'messiah' wasn't enough to eradicate the human race.
After the entirety of City Q was effortlessly taken over by that 'God', only then did all of humanity join together to fight against the threat.
One by one, the cities were conquered by the 'angels', millions of humans enslaved and billions more dead, the heroes fell and everything seemed lost when the rest of the S-class heroes, except me, fell.
Tatsumaki was defeated after a fierce battle with a legion of 432 'angels', and after her defeat, her mind was crippled by one of the 72 'archangels', mentally disabled to the point she was no more than a two-year old toddler.
Atomic Samurai fought against a group of 36 'angels', but fell when he tried to protect a shelter full of civilians until they evacuated. When he was caught, his arms were cut off by his own sword, and his own disciples' corpses, worn by the angels as a mockery of him, executed him with their own swords.
Silver Fang died protecting the entirety of City Q from the entire invading legion of 'angels', and finally perished after three 'archangels' worked together to kill him.
The fates of the other S-Class heroes were too gruesome to further discuss. Pig God was eaten alive by hundreds of 'angels', Superalloy Darkshine was constantly resurrected and killed in the 'arena' for the 'archangels's amusement, Child Emperor became a slave of one of the 12 'Spears of Heaven' and used as a 'pleasure thrall'. I need not say what happened to the rest of the heroes.
In a single day, more than 75% of Earth was taken over by 'God' and its 'angels'. Cities A to F were the only ones that were unconquered.
There seemed to be no way of fighting back, but a glimmer of hope appeared when the secret weapon of the Heroes Association appeared, the Rank 1 S-Class hero, Blast, appeared to stop the threat, yet after a long battle with 'God' that lasted a whole day, Blast fell.
I didn't know what took Saitama so long, but when he arrived... everything changed.
He single-handedly liberated all of cities G to U, excluding cities Q, L and P within two days, and on the third day, he fought with that 'God' on his own.
I was there, you know, at my apartment that was miraculously untouched. All of City M was taken over, yet the 'angels' had left my apartment alone for some reason. I was alone and piss-scared in my own apartment, yet I managed to lay eyes on when Saitama was battling that 'God'.
It was a slaughter. All the 'angels' that the 'God' had sent died in a single hit, sometimes killing dozens with a single punch. The 'archangels' were no problem, either. A single punch was all that was needed. It took Saitama seven seconds to kill all the 'Spears of Heaven', and in three punches, no less.
I saw when Saitama beat 'God' down to its knees. Every punch Saitama gave was a tremendous blow to 'God', yet Saitama was unfazed when that 'God' attacked him back. It was as if there was nothing that could harm him. Yet, despite how effortlessly which he beat that 'God', I had never seen Saitama so angry before. It wasn't the frustration of losing in a game, but it was sheer... rage.
Yet then, even then, that damned 'God' had a trick up its sleeves. He took out a weird black sphere and threw it at Saitama, and when Saitama punched it...
He disappeared.
That 'God' laughed, saying that he managed to trick Saitama into punching that sphere, which transported him at least 81,000 parallel universes away.
At that moment, when I saw Saitama disappear, and that 'God' laughing arrogantly, I didn't feel fear. I didn't feel despair. At that moment, I didn't feel anything. I just felt an emptiness inside me, and when I realized it, my heart was beating so hard and so fast that it attracted that 'God' to my position.
When that damned 'God' appeared in front of me, he simply laughed at me, saying 'So this is the famous King? I left your apartment alone in fear of your reputation, yet what do I see? A normal human with heart problems! How hilarious! I avoided a simple building just because of you, but it turns out that it was nothing after all!'
Even when he was laughing away, I felt no sorrow, no fear, nothing. My heart just kept beating, and beating, and beating, and finally...
I obtained it. The power to defeat that damned 'God'. Power was coursing through my veins, and I had never felt such strength before.
I barely realized my newfound power until that 'God' suddenly panicked, saying 'What!? How!? You had 'that power' the whole time!? So you were trapping me, tricking me to get nearer to you!? Shit!"
That 'God' ran away as fast as it could, and when I realized it, I was running towards it with such speed I caught up to that 'God' in less than three seconds. When I got my hands on it, my emptiness was then replaced with sheer rage, as if all of Saitama's anger was transferred to me at the last moment. I beat that 'God' with my fists, but took care not to kill it so fast. I wanted that being to suffer for what it did.
And after I was satisfied, and when that damned 'God' was begging me to kill it...
I ended it's pathetic existence.
And on that day, I freed all of Earth and drived the 'angels' to extinction.
{End of King (Older)'s Narration...}
"T-that's amazing! But wait, s-so Saitama didn't die?" The younger King asked, amazed at what he heard from the older King. If Saitama was so strong he brought that 'God' to the brink of defeat and only managed to transport him away due to a dirty trick, how strong was he?"
"No. As far as I know, Saitama-bro wasn't dead when that 'God' transported him away. Before I killed that 'God', I asked him where he sent Saitama. It said that it didn't know, that the orb was actually meant to be an escape device to somewhere far away, like literal universes away. I tried my best to find where he went afterwards but to no avail. I couldn't find him, even after 50 years of searching."
"I see... wait, 50? If I'm 28 right now, and I'm 29 next year..." The younger King looked at the older King with shock in his eyes. "You're 79!?"
The older King laughed. "146, actually. I spent much longer elsewhere."
"B-but you look barely any older than myself right now!"
"Well, let's just say that my newfound power has a lot of side-benefits, as well."
"W-what is my 'newfound power', anyway?" The younger King finally asked.
The older King smiled. "Did you ever wonder why your heartbeat was so loud? That it was normal?"
That put the younger King in deep thought. "That's true... I always wondered why my heart beat so loudly, I always assumed it was me being so scared that my heart beat just that much more loudly!"
"Y-you don't mean to say..." The younger King realized what the older King was pointing at.
"Yep, your special power..." The older King placed a fist directly above the younger King's heart. "...is this little thing over here."
"It's a simple power. I call it the 'King's Engine'. During the time I was still weak, the civilians around me would assume that my strong heartbeats were me in battle-mode, and thus they named it the 'King's Engine.' My power right now is basically something like that, as for every beat of my heart, my strength increases exponentially, like from ten, to a hundred, to ten thousand, and so on. I don't know the specific values, but my strength just increases like crazy after every beat."
Editor's Note: Just imagine the function y=x². His power is squared for every beat of the King's Engine.
"With every beat, my strength rises to the point I was basically like Saitama. With just 2 beats I could kill any average monster in one punch, and in five beats, I could destroy the planet with a single touch."
"B-but wouldn't that make daily living so much harder?" The younger King asked.
"No worries, the effect cancels out when the King Engine stops." The older King explained. "After a while, the King Engine stops and your power slowly drops until you're back to a normal human again."
The younger King was amazed, but he noticed a simple flaw.
"But, wouldn't that leave you open to surprise attacks?" The younger King asked.
"It would." The older King said simply. "But the simple solution would be to increase your base power without the King's Engine."
"You just need to train your body, simple as that. That way, you don't need to constantly rely on the 'King's Engine.'"
"I-I guess that makes sense... but why can't I just use it normally to kill monsters?" The younger King asked.
"Well, of course you can. But aside from being weak to surprise attacks..." The older King looked amused, as he moved in closer to the younger King. "For every power in this world, there's always a trade-off."
"Like a car engine when it's used too much, it can be damaged if you use it too much." The older King said. "When I just got it, I immediately used it to kill every last 'angel' on Earth. For five years I've been killing monsters without a second thought by using the 'King's Engine'. But after that=, I suddenly found out that sometimes, my 'King Engine' would go berserk, and not stop, even after I've killed the monster."
"The problem is that when I don't deactivate it, I will experience such a great surge of energy that I'd be able to destroy an entire solar system if I wasn't careful. So when that happens, I am forced to stay completely still, until the 'King Engine' wears off. Otherwise, not just the Earth, but the entire solar system, and if it doesn't wear off in a minute, you'd be able to completely annihilate an entire galaxy. The Milky Way, the nearby neighboring galaxies, reduced to space-dust."
"Even if I do manage to get through that without destroying the Earth, I will experience nausea and headaches afterwards, similar to when you stand up too fast. But aside from that, it would theoretically shorten my lifespan, but as the 'King Engine' brings me what seems to be eternal youth, I don't really know where my lifespan would end."
"For simplicity's sake, just think of the 'King's Engine' as a super-powerful steroid that boosts all your physical abilities, but if you use it too much, instead of causing adverse effects to yourself, you just become too strong."
"I see... wait, now that I think about it..." The younger King realized something. "Now that you're here... why don't you solve everything?"
"Heh. Let me tell you something, young me." The older King said. "You need to do things for yourself, too. If somehow, there's some threat that appears down the line that needs two 'King Engines' to solve, you'll be happy that you trained."
"Wait, there's a threat that needs two of us to defeat?" Younger King asked, panicking.
"Ah, no. I said that as an example." Older King said, relieving the younger King. "But still, I expected this long ago, so..." The older King then took out something out of his pocket.
"I brought all the future releases of Doki-Doki Sisters. Every time you get stronger, I'll give you the next edition."
"So when do we start?" The younger King said, a rare appearance of determination in his eyes.
"Heh, I knew it. Then again, I know myself better than anyone else." The older King said, amused.
"Oh, right, just asking, but how did you travel back in time?" The younger King asked.
"Ah, it's a simple affair, really. I just beat up some old titan guy until he agreed to send me back in time." The older King said. "He called himself Chronos or something."
"I-I see..." The younger King said, not expecting the way his older self came back to the past.
"So anyway, this'll be the main thing helping you get stronger." The older King said, taking out a card from his pocket, and handing it to King. "Just place it on any door or wall, and you'll get it."
The younger King took the card and read the words written on it.
"Time room?"
Hey, I hope you liked it, as you could read in the part of the room of time, you will have a few elements of other anime but not the big deal, I hope you enjoyed it
That was the prologue, any criticism will be welcome, even the negative ones.
I hope you liked it, any questions you can do, just like any advice. English is not my original language, so I would like to see what you think.
Editor's Note: I edited the chapter. Hope it's better.
