I'm currently doing re-writes of this story, so please don't get confused when the chapters don't quite line up chronologically. I plan to make more than 19 chapters. Not that they'll be made quickly or anything...

Izuku looked at the tiny All Might doll given to him for his birthday, staring at it in awe and joy and reviving the gift 'Thank you mommy!' He yelled and hugged her 'Your welcome Izuku!' They smiled as they ate his All Might themed cake.

Ever since he saw All Mights debut video, the boy had been obsessed with him, saying how All Might was his most favorite hero. The number 1 Hero had an affect on people, making them admire the man to an enormous degree.

Heck, he admired All Might more than he admired his own father. Inko looked at her child with happiness as they heard a knock on the door, and there stood a man with dark messy hair and piercing black eyes: Izuku's father and Inko's husband, Hizashi Midoriya.

'Hi honey.' The man had roses in his hand as Inko stood up in surprise 'H-Hizashi! What are you-' The 4 year old ran to his father and hugged his leg 'Daddy!' Hizashi picked up Izuku and looked at his son.

'Wow! Is this Izuku, or a pro hero?' He asked with a joking smile, making Izuku giggle to himself 'I'm both daddy.' Hizashi set Izuku down and walked over to Inko, hugging his wife after months of being gone overseas.

'I can't believe your here...' She said quietly as he hummed to himself 'Well I got a bit of time off, but...' She was now starting to hate whenever Hizashi said "But" it always ended with his having to be gone longer or farther away from them.

'I have to stay over seas for a few more years, it's just getting busier and busier and well...the pay is kinda worth it right?' Inko huffed and tears began to form from her eyes 'Money may help us, but it can never give us happy, joy filled family moments like the one going on right now. It's just can't.' The brunette sighed and kissed his wife's cheek.

'I can make it to a few more birthdays in the future, and maybe some funerals or marriages...but that's it.' The greenette sighed to herself as Izuku walked up to Hizashi and held up his newly given All Might doll 'Look at what mommy gave me daddy!' Hizashi looked at the doll and picked it up 'Wow, it almost looks just like him, but tiny!' Izuku nodded as Hizashi handed the doll back to him.

'Hey Izuku,' Hizashi squatted down 'Did you know that I once met All Might?' Izuku shook his head and looked at him curiosity and excitement 'I didn't meet him for long but, what I can feel you was that he was tall,'

The day ran through his mind, with Nana Shinura dying by his hand, with an 18-19 year old kid behind her, being carried off by a man with white hair.

'boisterous,'

All Mights eyes were filled to the brim and spilling out with tears, his cry of sorrow and anger outdoing other cry's of those dying in the nearby burning buildings and rubble collapsing all around them, filling the smog night sky.

'and was very passionate about his friends and job.' Hizashi smiled and pulled out a little box from his black tuxedo pocket, the little yellow present wrapped in a purple ribbon with "For: Izuku" on a tiny card attached to it.

'Here you go, my present to you.' Izuku unwrapped the box and opened the tiny lid to reveal a tiny All Might keychain and a silver pocket watch, with Roman numerals inscribed behind the glass. Izuku stared at the item and flipped it over, seeing some kanji etched into the back of it.

'What does this say dad?' Izuku asked as Hizashi read it out loud 'Time is important for heroes like you.' The tiny greenette smiled and hugged his father 'Thank you daddy. I'll keep it forever and ever.' The man smiled and stood up, getting the blood flowing in his legs.

'Now for a little advice Izuku: know when and when not to do something alright? Timing can be everything in many situations so you gotta know when you have to do something, like saving multiple people, or writing paperwork after you do your patrols. It can be crucial alright?' The 3 year old nodded as he let out a breath of relaxation.

Although he despised heroes, and his sons love for All Might, he couldn't help but brew a perfect plan to counter both: make sure Izuku does what he tells him to, it would be perfect, and it would save him a bit of trouble in the long run. Especially with him training Shigaraki in secret.

He finally devised a perfect plan to counteract Izuku's love of heroes; make a personality that despises them as much as he does, and make it so this personality will be a foil to Izuku's dream to become a hero. But this personality needs a name. It can't be a reversal of Izuku's name nor can it be similar to his sons name.

Maybe he can use the name they were gonna give Izuku before Inko changed it at the last minute when he was born. This personality's name was to be Yamikumo, the perfect son he didn't get before. Now, how to make a alternate personality unknown to the main personality used by the body...

Perhaps a traumatic experience would create the personality he needed. Yes, that may in fact be perfect, but what would be suitable for Izuku to experience. 3 year olds aren't known for their great memory...but maybe he can show him a memory that he bas, and then shut that memory out from his conscious mind, letting it develop over time along with his base personality.

Then, when's it's time to strike, he would unleash the memory, setting it free in his body to use the Quirk that they would both share with each other. Yes, this plan is becoming more and more fun with every second. But what memory? And how would he transmit this memory, and then erase it from his conscious mind?

What would spark a hatred for All Might and all other heroes? What about... Hizashi thought back to when he fought the One for All users, their hatred for him and the way they died was ever so satisfying. He knew All Might was next, but he didn't know when their confrontation was to be, and where it might take place.

Hizashi took out his phone and called up the doctor 'Hello, what do you need master?' The old man replied on the other end of the phone 'I need you to work on a memory transferring device, where I can copy my memories and share them with my son, and hen shut those memories out from his conscious mind, making an alternate personality.'

'And what would you call this personality sir?' Hizashi smiled to himself as the name came to his mind 'The name will be Yamikumo.' The old man on the other side wrote the name down 'Alright then sir, I'll get to work on the device. It will be ready in a few days.'

'Good. I need this plan to go as smoothly as possible...' Hizashi ended the call and fixed his tuxedo, looking in the mirror as his devious smile turned soft and more sullen. Making his son an experiment was not on his mind when conceiving him, but it must be done. Besides, Izuku might even have a good Quirk for Yamikumo to use in the near future.

Izuku stood there, but it wasn't Izuku. His eyes were a dark crimson red, his voice...wasn't his voice, and he was out of control. The U.A. building was burning, crumbling under the damage taken in the lower levels. Izuku looked on at Momo, his body covered in cuts and his clothes partially ripped off his body.

Izuku's hair was flowing in the cold breeze, his breath was calm, despite the damage he had done to the high school. He seemed dazed, not quite there, but moved faster than the eyes could possibly see. He stepped forward, the building under them rumbling in pain as it fell apart down below.

'Midoriya please!' Momo begged in desperation 'Stop this! End this madness I beg of you!' Izuku looked at her and gave her a sicking laugh that made her stomach turn. '̸M̸i̷d̴o̵r̷i̵y̶a̶ ̶i̷s̵ ̸a̸s̸l̴e̶e̸p̴.̶ ̸I̶,̵ ̷Y̴a̸m̴i̵k̸u̶m̸o̵,̸ ̵a̴m̷ ̶r̶e̶p̵l̴a̵c̷i̶n̴g̶ ̵h̴i̵m̷ ̷i̷n̵d̷e̷f̷i̶n̵i̸t̶e̶l̵y̶.̵ ̴E̶n̶j̷o̷y̶ ̵t̸h̸e̶ ̵r̸i̷d̷e̶.̷'̵ He lifted his arm as bright orange flames shot forth at the girl; her screams being heard from miles around.
