What If ?

Chapter 1: The Mistake.

I awoke with a gasp, although I lacked a physical body to draw breath. The starry sky above me sparkled with hypnotic lights. My previous life played in my mind with perfect clarity - an ordinary existence of learning, working, starting a family, and eventually succumbing to old age. There was nothing exceptional about my life; I was far from a virtuous individual, lacking the good karma often associated with reincarnation stories I used to enjoy as entertainment. I often fantasized about wielding personal power, contemplating what it would be like to be an apex being in a world of my own.

Suddenly, an ethereal voice resonated around me, breaking my thoughts. "Aha, you are correct in that, you have no good karma. You are nothing, just a little speck in the wheel of life and death. I choose you randomly." I glanced around and questioned the unseen entity, "What are you? What do you want with me?"

"It doesn't matter what I am. What matters is what we can agree on," the voice replied. "If you disagree, nothing will happen, and you will be thrown into the wheel, where you shall be recycled and born anew. The offer is this: I need personal entertainment. As an omni-being, even the multiverse is starting to become boring for me. There is a small enemy of mine that has spread across many universes. Your job is to hunt down beings corrupted by him. You can have four wishes for power. The first world you will be born into is A Song of Ice and Fire. It is a world where many entities are infected by my enemy. You must destroy them, find the veil of death present in every world, and walk through it to leave the world. At that time, you can keep any powers, possessions, and travel to the next world. You will be non-aging and functionally immortal, but you can be killed like any other mortal. So, choose your powers wisely."

The opportunity overwhelmed me. To visit Westeros, one of my favourite TV series worlds, was tempting. The offer of any powers was irresistible, despite the restrictions. I envisioned being overpowered and enjoying life in the new world.

"Naa naa," the voice chastised. "Let me clarify. You cannot choose any powers that would break the world. Only unremarkable powers can be selected. The more power you wish for, the more the world increases in danger. Let me help you with this, You are going to be a son of the most powerful magical bloodlines of that world, so choose your wishes with that in mind "

Undeterred, I carefully considered my wishes, knowing that personal power was crucial in the tumultuous world of Westeros.

"Of course, I will keep that in mind," I replied. It seemed to me that I would be reborn as Jon Snow, with the Stark and Targaryen bloodlines, promising a unique combination of magical potential. Being a bastard in Westeros was a challenge, and I deemed being a Targaryen without a dragon worthless. My resolve solidified: I want to be both physically and magically powerful, preparing the North for the impending Long Night. The Night's King or White walkers or others, will be infected by the Great Enemy of this Omni-Being. It will be impossible if they have 8000 years of corpses saved up

After contemplating the dire challenges ahead, I presented my wishes to the Omni-Being.

"Omni-Being, my wishes are: I want to have limitless potential along with control of mind, body, and soul." The being nodded, acknowledging the intelligence in my choice. It assured me that this wish would not cause major changes in the danger level.

"I want to have the adaptation powers of Doomsday," I declared, considering the hazardous landscape of Westeros. The being, however, deemed this power too world-breaking. I cursed at my bad luck, undeterred, I proposed a modified version, removing the resurrection aspect and limiting the adaptation to 1% of Doomsday, with healing up to twenty percent of Wolverine's capabilities.

"You are a greedy little shit, The limitless potential and adaptation will help you grow more than the world's power level, but since the base is not world breaking, I will allow it. Know that there will be consequences for this wish. The world will be changed from what you expect and foreknowledge would be the lowest cost for this wish." the being retorted.

For my next wish, I requested the ability to temporarily pass my adaptation and regeneration power from every part of my body, including blood, only with willful donation from me, if it was present in the consumed being's physical structure.

The Being at first laughed mockingly and said, "I never pegged you for such a selfless person. Whatever, it is acceptable. Know that fate is cold bitch and if you increase the world's power level too much then my enemy can also increase it, but you are in luck, as the great enemy as increased his powers so much now that it would be very hard for you to be affected by this cost."

Expressing gratitude for the information, I presented my fourth wish. I sought the talent for instinctual learning of everything – psychic, martial, social, soul, and magic talents – inspired by stories from the Waifu Catalogue. To mitigate the cost, I requested a slower development than the original talents.

"Hmm," the being nodded, recognizing my cunning approach. It remarked on the seemingly modest power of each wish individually but acknowledged the potential when combined. With an enigmatic declaration, the being concluded, "The base is strong, may the Fate let you develop it. Let the game of thrones begin."

As the being's words faded, a bright light enveloped me, and consciousness slipped away into the unknown.

----------------------------------------------------------------------------------------------------------------------

I knew something was wrong the moment I first awoke. The first thing that made me realize this was that I could feel my body, and it was not the baby body of Jon Snow. I barely opened my eyes and saw that I was lying in a pool of blood in an alley between two modern buildings. I tried to move and felt agony all over me as my healing powers patched my still-broken bones. I moved to the wall and tried to sit up but couldn’t due to the pain. I groaned and lay in the filth, closing my eyes and trying to remember anything.

My mind went through my old life, meeting the being who promised to send me to the GOT world. I tried to remember what happened after that, and suddenly, some of the memories of this body hit me.

Fucking hell! Why is my twin named Izuku Midoriya, and why are my thoughts in Japanese?

I remembered my name, Mikumo Midoriya, called MM by Izuku, and quirkless just like him. The memories and feelings made me realize that today is the day Izuku meets All Might and the day Bakugo gave his infamous advice. It seems that the tale of the good twin and evil twin is correct. For good or bad, Mikumo was furious with the world and was only one bad day away from bombing the school. He may have succeeded too because both of us were very intelligent. This was the day of revenge for Mikumo as he recorded Bakugo's suicide baiting Izuku and me. After school, he got into a fight with them here. It was during my beatdown by them that the Sludge Villain attacked Bakugo.

I ran away, climbed a building, recorded a video showing my injuries, and set it to be released everywhere in 24 hours before jumping.

I groaned again as Mikumo was spiteful enough to kill himself just to make sure Bakugo never became a hero.

By my memories, it was almost evening when I jumped, and now it was nearing morning. I was amazed that no one had found the blood or seen my body slowly healing as I lay there. I was pretty sure my family would be worried out of their minds since I didn’t show up at home. I knew Izuku would start training with All Might as it is a turning point for this world.

I tried to imagine the Great Being, tried to contact him and ask what happened, but there was no response. The entity had given me the mission of ending its enemy's influence in the ASOIAF world, and I picked my wishes based on that world’s power level. I don’t know if there is the Great Enemy's influence here or not. I cursed the being for getting sloppy, transmigrating me into the wrong world, in the wrong body, and that too in a dangerous world.

I thought about the upcoming year and all the danger it would bring. I wondered what would happen with my involvement and decided it would be too much of a headache to be in front of the eyes of All Might, AFO, and Nezu. It would be better if I stayed dead, and it would also be a great “fuck you” to that bitch Bakugo. I decided that I would improve by fighting underground, staying below the notice of everyone, and slowly start gathering strength. My own talent would allow me to pick up quirks that I could see people using, and it would be a great cheat code for this world.

Even with my mind being entirely mine and nothing of Mikumo’s, I felt sad for the agony this would bring my family. I could picture exactly how Izuku would cry and how a determined look would come over his face, ensuring no one else would do this. I hoped my own death wouldn’t impact his performance that much. I could still picture him trying to make All Might smile and being a fan. I could still remember the arguments we had about whether All Might or Omni-Man was the strongest and who would win in a fight. Izuku always chose All Might, and I would choose Omni-Man. A smile enveloped my face remembering the good times, but suddenly it became a frown.

“Wait! What did I just think about? Fucking Omni-Man? Why the hell would I compare a fictional Omni-Man with All Might?” I tried to remember, and finally, a memory became clear in my mind.

A memory of a fight in America, a fight between a white-robed man with a red "O" symbol and a kaiju for hours until Star Stripe entered with a military escort and used the Hammer of God to kill the kaiju.

Slowly, I remembered the frown and displeasure I thought I saw on Omni-Man’s face during the press meet after that, and my own thoughts came to a halt. A chill enveloped my entire being, knowing that Viltrumites were coming.

“Fuck you, Great Being! I was to be the king, and not only did you send me to the wrong world, you sent me to a fucked-up crossover of Invincible with MHA, or MHA where aliens exist.”

“Fuck you,” I yelled to the heavens as every single plan I had was discarded. I decided that being near my twin brother would be best for me to rapidly gain power in the near future.
