I don't own anything. The chaotic scene inside Odin's throne room was intense as the mighty god of Asgard stood before his rebellious son, Loki. The air was tense as Odin's anger radiated from his eyes, and Loki could feel the weight of his father's judgement upon him.

"You have gone too far, Loki. Your actions on Earth have caused great chaos and destruction," Odin's booming voice echoed through the hall.

Loki couldn't help but smirk, even in the face of his father's wrath. "Oh, but father, isn't that what I'm known for? Chaos and destruction?"

Odin's patience was running thin, and he could not let Loki's arrogance go unpunished. With a flick of his hand, he cast a powerful spell upon Loki, transforming the mischievous god into a baby.

Loki's eyes widened in shock as he found himself in a small, helpless body. But what was even more shocking was the fact that he had lost all his memories. He had no recollection of his time as a god, nor his schemes to destroy Earth.

As a baby, Loki was adopted by a kind couple, the Potters, who lived in a small town called Godric's Hollow. They named him Harry, and from the outside, he appeared to be a normal baby. But inside, there was a constant struggle for control.

You see, Odin's punishment was not just to transform Loki into a baby, but to also merge his memories with a young Harry Potter, who was the same age as Loki. This meant that both Loki and Harry shared the same body and were constantly fighting for control.

Harry would often experience blackouts and lose control to Loki. And during those times, he would unleash the full extent of his sadistic nature. Death Eaters and their children were his targets, and he took great pleasure in torturing and killing them in the most brutal ways. He didn't care about the consequences; all he cared about was satisfying his twisted desires.

But deep down, Harry was horrified by his own actions. He could feel the darkness consuming him and the guilt gnawing at his soul. He knew it was Loki's influence, but he couldn't do anything to stop it.

Harry's friends, Ron and Hermione, noticed the drastic changes in his behavior and tried to intervene. But every time they got close to the truth, Loki would take over and push them away. He didn't want anyone to get in the way of his sadistic games.

The only person who seemed to understand Harry-Loki was Draco Malfoy. He was the only one who knew about the two souls inhabiting one body. Draco was fascinated by the concept and would often try to communicate with Loki.

But Harry-Loki was too far gone to listen. He was consumed by his own darkness and the power he wielded. For him, there was no turning back.

One day, Harry-Loki received a vision of Voldemort's final horcrux. It was the source of his powers and his connection to the dark wizard. Without thinking, he went after it, determined to destroy it and end Voldemort's reign of terror.

But as he fought, he felt a strange pull towards the horcrux. It was like he was being drawn to it, and before he knew it, he had absorbed it into his body.

In that moment, everything changed. Harry-Loki no longer felt the constant struggle for control. Instead, he could feel his memories merging with Loki's, as if they were becoming one.

In the end, it was Harry who emerged as the dominant persona. He was no longer Harry-Loki, but simply Harry Potter. But he was not the same boy who had entered that fight. He was now a combination of Harry's goodness and Loki's darkness.

Harry was torn. On one hand, he finally had control over his own body and could make his own decisions. But on the other hand, he was responsible for the deaths of so many, and the knowledge of what he had done weighed heavily on his conscience.

The people who had once trusted and loved Harry were now afraid and disgusted by him. They saw him as a monster, a killer. And Harry couldn't blame them.

But he refused to give up. He was determined to make things right, to earn back the trust of his loved ones. It would be a long and difficult journey, but Harry was determined to change the narrative of his life.

As for Loki, he still occasionally had psychotic breaks, but with Harry's control, he could no longer act on his sadistic impulses. He would forever remain a part of Harry, a reminder of his past mistakes and the power of redemption.

In the end, Harry realized that even with all the darkness inside him, he could still choose to do what was right. And that was what truly mattered.
