He could go to the Forbidden Forest. It's a large and mysterious place where he could hide. There are many hiding spots and magical creatures that could either protect him or at least keep his presence a secret.
He could go to the mountains. There are so many hidden caves and areas in the mountains that he could explore. It would be a great place for him to hide and be alone with his thoughts. Plus, there might be some powerful Pokémon that live there that he could interact with.
He might go to his mother's place. It's a place where he has always felt safe and loved. His mother has always been his anchor, and even though it might be a risky move as monsters could track him there, it could be his first instinct. Another option could be to go to a big city like New York. There are so many people and places to hide. He could blend in with the crowds and use the chaos of the city to stay unnoticed. He could also find refuge in an abandoned building or a place that has some sort of magical protection that he discovers by accident.
One possible reason could be to escape the pressure of his family's expectations. The Malfoy family has a long - standing reputation in the wizarding world, and Draco might feel suffocated by the need to uphold it. Another reason could be fear. If he's gotten involved in something dangerous, like with the Death Eaters, he might run away to avoid the consequences.
She could go to the mountains. The high peaks are often seen as a place of solitude and mystery in many stories. There, she might find a cave where she can hide and think about her life. It could also be a place where she discovers some long - forgotten magic that has been dormant for ages.
He could run to the Land of Waves. He has a connection there from his early mission. The people there were friendly to him, and he might find some peace and acceptance among them. It's a place where he could start anew, away from the chaos of Konoha.
He could go to Hogwarts early. Since he has some connection to the school already through his parents, he might think that the school could be a safe haven. There are also his friends' families there, like the Weasleys, who might take him in.
He could run to a beach town. Imagine Jungkook running away to a small beach town with white sandy beaches and clear blue water. He could rent a small cottage by the sea, where he can wake up to the sound of waves crashing. It would be a peaceful place for him to relax, away from the hustle and bustle of the city and the chaos of his idol life.
He could stumble upon a hidden wizarding community that has been cut off from the rest of the world for centuries. There, he might learn new magic spells and techniques that are unknown to the outside wizarding world.
Maybe he discovers some dark secrets within his own superhero community or organization. Fearing for his safety and not knowing who to trust, he decides to run away and figure things out alone. For example, if he finds out that some of his allies are involved in unethical experiments related to their powers, he might feel the need to escape and expose the truth from a distance.
One possible plot could be that Mal runs away to escape some kind of danger in her world. Maybe there's a powerful enemy after her and she decides the best option is to flee and find a safe haven. She might encounter new friends or allies during her journey who help her face her fears and the threats.
