AUTHOR'S NOTE:

Hey everyone, this my first fanfic and I'm writing because I was looking through the My Hero Academia x Percy Jackson and the Olympians stories and noticed it's pretty barren for stories and the stories that are there are either not getting updated or not to my taste. I have wanted to write a fanfic before and I know a decent amount of both of these fandoms that I feel comfortable starting with a crossover of both. I'm this because I want to see more fanfics in this crossover and I want to practice my writing skills. Without further ado, on with the story.

Disclaimer: I don't own PJO or MHA, and I am making no profit from the use of the characters or settings from either series.

Prologue:

I heard the sounds of battle and the as the battle of Manhattan raged on, the other demigods falling around me one by one. I had to end this now. The sound of tearing winds surrounded me as I tore through the army of Kronos in front of the Empire state building as cleaved my way to the leader of this army of monsters. There he was, 100 feet in front of me commanding his army to push forward and overwhelm the demigods while he stood on the shoulder of a Hyper Boreas to get an eagle eye view and our eyes connect. Eyes a bright sickly gold stared into my soul.

We stared at each other. Not blinking or moving. My localized hurricane turning any monsters stupid enough to approach into wet golden dust. Him firing the occasional bolt of energy or slowing down time on my friends and the hunters. Then we made our moves. I charged towards him cutting through the enemy, and him drawing Backbiter, transforming it into his traditional scythe, and slashing down his own troops to get to me.

4 seconds to impact...

I focused everything on my greatest enemy, forgetting about sides and only about killing Kronos.

3 seconds to impact...

We kept looking into each other's eyes, and I see it, a flicker. Of what I don't know but the Eyes seemed to lessen in the intensity of their glow for a fraction of a second.

2 seconds to impact...

A battle cry rips from my throat and I hear one torn from the lips of the possessed son of Hermes.

1 seconds to impact...

I'm sorry everyone, but this ends here. One way or another.

0.5 seconds to impact...

My life flashes before my eyes. All of my friends and family, all of my adventures. I will miss them when I'm dead. I might go for rebirth, go for the isles of the blessed...

KRAKOOOOOOOOOOOOOOOOM!

The sound of us clashing didn't sound like two pieces of metal but rather an explosion. The ringing in my ears wouldn't stop as we continued to clash. Kronos slowing time and me lashing out with my hurricane. Our actions slowed by each other's powers. Even then both of us moved with blurred movements and with a deadly grace. Neither of us giving an inch. The only noises were the sounds where of screeching metal, cracks of wood, and the screaming of the hurricane. We circled, sliced, parried, stabbed, blocked, and dogged for what felt like hours, never letting up the pressure on the other. When he started to glow with a golden light.

"It is over Perseus Jackson, I am acceding to my divine form, and with it, you will lose grandson!" the cackling echoed off the surrounding buildings.

I don't respond as I am too focused on something. The only spot that is not glowing is his armpit. With him gloating, I use his moment of distraction to attack. One millisecond before I stab him, he realizes his mistake too late.

"RAAAAAAAAAAWWWWWWWWWWR," Kronos bellowed as ichor and blood flowed out of his wound.

He stumbled. The possessed blond fell to one knee then onto his face. His glow flickering. The battlefield went silent. Everyone in shock. The titan lord was defeated...

Terrifying screeching and roaring came from the monsters as they fled. Not even one minute had passed since Kronos' defeat and his army was shattered. The demigods and hunters still looking on in shock. One minute ticked by, then another, then the demigods began to cheer and celebrate. All things considered, they had only a handful from both campers and hunters. The losses sting but there will be time to morn later, now was the time to sigh in relief.

"CuRsE yOu JaCkSoN..." a weak and raspy voice called from beside me. "YoU wIlL bE sEnT tO aNoThEr ReAlItY wItHoUt AnY pOsSiBiLiTy Of ReTuRnInG. iN a WoRlD wHeRe YoU wIlL nEvEr FiT iN nO mAtTeR wHaT yOu Do, FoRcEd To LiVe OuT tHe ReSt Of YoUr DaYs..."

I Turn to look at the defeated titan, and see that he is glowing more and more. Without warning a bolt of light shoots at me and hits me square in the chest, and everything goes dark...

"I'M GOING TO BE LATE!" a boy with dark green hair and emerald eyes yells waking up. He had overslept and was going to be late to UA, the school of his dreams. Today was the first day of classes and he wanted to make a good impression on his teachers and classmates. He bolted out of his room and over to the bath room in the small apartment that he shared with his mother. He had a 5-minute shower and grab a few bites of the meal that his mother had made for him before rushing out the door.

"Love you mom! See you tonight!" The boy now in a grey school uniform with a white dress shirt under the grey buttoned up coat and a red tie.

"Love you Izuku! Have a good day at school!" Yells the green haired woman as her pride and joy left the house in a rush. She still couldn't believe that her little boy was attending the prestigious school that was renowned for its unparalleled prowess in training pro heroes...

The boy made his way to the train that would take him to his new high school with as much speed as he could without using his quirk. Izuku Midoriya did not want to break his legs just getting to the school after all. It took the train 30 minutes after he got on to get to the train stop that was closest to UA. It was only a 15-minute run to UA from here if he pushed himself and he would have 10 minutes to look for his class room.

Izuku was so wrapped up in his own world that he didn't hear or see the bright flash and bang that occurred in a nearby ally. As the street was deserted except for him, no one was there to hear the groan from the figure that appeared out of the flash of golden light...
