Battle of Ages

It's been 11 years since I have reincarnated into the world of My Hero Academia. And I have to say this is kinda fun. For the first year being reborn I have vigorously trained my Ki to an amazing level and now I can create Ki blades and weapons. The second year I tried to recreate iconic attacks from dragon ball such as: the Kamehama, Galic Gun, Destructo Disc, Death Beam, Big Bang Attack and of course Instant Transmission. I also learned how to fly.

Which I succeeded after weeks of trial and error. I also made many more and some of Android 21 signature moves such as: Total Detonation ball, Absolute Release ball, Photon Wave, Connoisseur Cut, Excellent Full Course and Appetizing Rush.

In the third year I tried something I didn't know if I could turn back on and that was the Majin Transformation. I went to the opposite side of the world to do this since I didn't actually know what would happen. When I was alone, I started to power up. The pink aura enveloped my body and expanded past it. The ground shook, rocks began to levitate, the ground caved in, and the trees became uprooted. The sky became dark, and lightning began to fall down, and my power kept spring past new heights.

Dust swirled around my power like a raging tornado. I felt something coming out of myself and I embraced it. I slowly calmed down my raging power and then I saw myself. My previous tannish skin turned into a pinkish color, my ears became pointed like an elf, my fingernails turned black and almost razor sharp, while my brown hair had turned into a white color and a tail grew above my butt. My usual clothes also changed as I now wore a black tube top, black arm sleeves, and white baggy pants. I didn't have any earrings or bracelets on my person. But the power that radiated off of myself surprised me. I was at least 10 to 20 times stronger than my base. Which is a great power up. And since I had an infinite potential, I could continuously keep growing stronger.

"While I am in this form I might as well test it a bit." I said while getting into a fighting stance and then punched the air. The pressure from the punch carried on until the trees in front of me exploded for a couple of meters. I looked at my hand in surprise then continued. I delivered punches, kicks and energy blasts in the surrounding area for about 10 minutes. I was grinning ear to ear at this amazing power I acquired.

After a test of my full power, I slowly suppressed my power until I transformed back into my human form. I was kinda worried because I didn't know if I could actually turn back. But I was happy that I could.

In the fourth and fifth year it was the same with me improving my ability and training. Around this time is when I found out the Saiyan DNA is making me something of a training maniac. And I have been wanting to battle someone strong. This wasn't that much of a problem since I can contain my lust for battle, and I was always fighting my mother. I have to say she is an actual monster if you piss her off. I actually saw my life flash before my eyes when I say that demons face. And I'm extremely durable coupled with my regeneration I am almost unkillable physically at least.

In the sixth year I felt a disturbance in the Ki around Japan. It was very subtle so it's not like anyone would actually notice it. So, I used instant transmission which is extremely useful in this world since no one could actually sense Ki or sense the disturbance in space from my presence.

When I arrived at my destination, I saw something I almost forgot about, it was the fight between All Might and All for One. I didn't really want to get noticed in my normal appearance, so I used my Majin form or my True form to disguise myself. I then hid on top of a building that wasn't destroyed yet. I then began to watch the fight.

…

"All for One!! I will kill you for what you did to my master!" screamed All might while launching towards A.F.O. All A.F.O did sneer and laugh at the man called the symbol of peace. "Haha all you'll do is die pitifully just like your pathetic master." A.F.O said with a smile mocking All Might.

All for One was a muscular man with white hair and red eyes. He wears a black suit with a white button shirt and black loafers. With his handsome face any woman could potentially fall in love with him if it weren't for his bloodlust and Killing intent directed at All Might.

All Might is a very large man with an equally muscular and well-defined physique, his design resembling a typical western comic book superhero. He has chiseled features on his face with a strong jawline and pronounced cheekbones, and bushy eyebrows. He has short blond hair, swept backwards, with two distinct tufts that stick up above his head, leaning slightly to each side. His strong features regularly cast a dark shadow over his face, hiding everything but his bright blue eyes.

Feeling the rage in his heart, All Might pull his arm getting ready for a SMASH. "CALIFORNIA SMA-" All Might said launching his arm forward into a punch gathering pressure from the wind into a massive attack but was interrupted as black tendrils launched out of A.F.O grabbing his leg and flinging him around before smashing him into a building, destroying the wall.

"Really is that all you have? How pitiful." A.F.O said, mocking All Might once again. All Might grinded his teeth in pure anger and fury. Getting back up, his rage turned into power as he ran towards A.F.O once again but this time much faster than before, this didn't surprise him at all. A.F.O calmly analyzed All Might as he made his way to himself.

Preparing another attack All Might cocked his fist back and punched forward sending a blast of wind towards A.F.O making him lose his balance and pushed back a couple of feet. But that was more than enough time to close the distance. In an instant All Might appeared in front of A.F.O getting ready for another devastating punch.

Feeling danger in this attack A.F.O launched his own attack. Cocking back his own fist he muttered "Three strength enhancements, two Impact enhancement, pressure pierce." Pushing his fist towards all might cause a pressure of air piercing his stomach destroying it along with his lungs but that didn't stop him. All might leaped in gathering his remaining power as used this moment of stun and used his Ultimate move. "United States of SMASH!!" All might cry landing his powerful attack onto A.F.O head turning his handsome face into something from a horror movie. With his skull caved in he immediately lost consciousness and is barely breathing.

With All Might winning the toughest battle of his life and killing his greatest adversary he muttered a few words before passing out, falling to the hard earth, "I avenged you master." With a smile on his face, he didn't even notice the pink girl with white hair and a tail.

"Such a marvelous fight. Ahh, I wish I could fight both of you but from just your intent I got scared. I still need training. But I wonder how you are still alive. No one could survive that." Aki said, questioning both of the dying men. "Now the question is: Should I kill you, All for One? You will be an astronomical pain in the ass in the future. But I haven't killed anyone yet so should you be my first. Or should I devour you. Would you be sweet, bitter, or sour? Ah, but your will is incredibly strong and might actually influence me just a bit. So, I should probably kill you right now. No hard feelings." Aki began her dilemma before making her decision.

Holding out her palm and a cruel smile appeared on her face, one she didn't know she had on herself. Not a moment later a pink energy blast formed on her palm ready to destroy anything in its path. But something told her not to kill him, if she did then there would be dire consequences. The presence reminded her of that god that reincarnated her although much weaker but still stronger than herself.

"Hah, here I was going to save myself so much trouble and so many lives in the future. Whatever it's your call." Aki sighed, not bothering to heal anyone and started to walk away until she transformed back into her human form and used instant transmission to teleport away.

Faintly opening his eyes, All for One saw movement before it disappeared. He didn't know who it was, what they looked like or sounded like, all he knew was someone was watching his fight with All Might. He didn't know if it was a hero or villain but since didn't get taken away it wasn't likely to be a hero and since he wasn't dead, not a villain. 'An unknown third party.' A.F.O thought before he let his consciousness go black, he activated one of his quirks called warp. A viscous liquid like sludge covered his body and he disappeared.
