This story is of a young man who's hated by everyone except for a few people.

In a world divided by heroes and villains, one young hero stands at the crossroads of two great nations. Raised in the shadow of America's greatest symbol of strength and justice, Izuku Midoriya-Bate dreams not just of saving lives-but of uniting worlds. Trained from childhood by the legendary Star and Stripe, Izuku possesses a power that defies the very fabric of reality. Though his abilities remain shrouded in mystery, one thing is certain: he wields the strength to change fate itself. Now, as he enters U.A. High School under the watchful eye of Japan's greatest heroes, Izuku must navigate a world that views him as both symbol and enigma. Bound by his mother's legacy and driven by his own unyielding sense of justice, he sets out to prove that the spirit of liberty is not confined to borders-it's destined to soar. But the path to greatness is never without struggle, and Izuku will soon discover that being a symbol means standing tall, even when the whole world is watching. Justice is not just a word. It's a promise.

As the big 3 of 1-A stood in the plaza just behind All Might a powerful aura filled the entirety of the USJ. One so evil they choked on it and felt themselves kneeling. The Hand Villain cackled at his newest subordinate's arrival. All Might was barely breathing as he had just narrowly defeated the Nomu. When a voice twisted by wroth and elation boomed through the battlefield. Several figures recognized that distorted voice and most felt their spines tremble so much they were frozen in place. One smiled as the figure stood before All Might blade in hand and pure rage in his eyes. His voice boomed like thunder as he smiled viciously. Izuku Midoriya has returned and his vengeance will be fulfilled.

I've never seen a fanfic that turns Izuku into Undyne. Let's fix that.

What if Izuku was the reincarnation of Son Goku and Tomura Shigaraki was the reincarnation of Frieza?

(This is inspired by Familiar of Zero and Vermeil of Gold.) Izuku Midoriya was a normal student in a magical school and lived with his mother. But the one thing that makes him an odd duck is that he doesn't have a familiar like anyone else did in his academy. So, he decided to summon one. Izuku found an ancient book in the library. After he went home, Izuku started performing a ritual, as the boy was able to summon a familiar. But not what he expected. What did he summon? Well, you'll have to read and find out.

Aizawa announced to the class that there would be a family day at the school in a few days. That they had to tell their parents to come to see them. Everyone was excited but some were nervous due to a certain crush they had with a certain cinnamon roll. However, that certain cinnamon roll didn't want to come to school that day. Izuku Midoriya when he was young he lost his parents due to a mugger and he was there. When it was time for him to present he didn't have anything. He wanted to crawl up in a ball to cry but that's when the door opened and someone kicked him and put his head in a head lock. The class was confused except for the Bakugo Family knowing who he was. That's when a woman appears that looks like Izuku beat up both of them. The woman revealed that she is Izuma Midoriya and the man is Izuka Midoriya they are the older siblings of Izuku Midoriya.

After being thrown into a max cell everything went to hell for the hero's.

Antares the Monarch of Destruction after he was killed by Jin woo and the rulers he though everything was over for him but to his surprise his soul gets transferred to a young boy named izuku Yagi

Forgotten, Neglected, Bullied, Abused, Hated, Scorned. That was the life that Izuku FORMERLY Yagi experienced as he suffered through hell and back. Ever since he was four years old, he had felt nothing but scorn and hatred from his family and former friends for something that he couldn't control, the only ones who were there for him were his sister Izumi along with Katsumi Bakugo and Shoko Todoroki. For being quirkless, that was all the reason they needed to hate him and treat him like he was filth, like he was less than human. No one cared for him with the exception of his uncles and aunts and grandparent-figures who were unaware of what he was going through. Finally, on his 5th "birthday", his so called "mother" took him to a secret organization called Crimson Starr who he was sold to, and for two years he was put through more hell as he was being experimented on which gave him great power, power that was beyond quirks, power that made him...like a God! With his new powers, he finally escaped that hellhole and fled til he was eventually found by a certain Owl who took him in as his life changes for the better and it becomes an interesting life nonetheless.
