Well, one possibility could be that Harry discovers a magical portal that leads to another planet. He leaves Earth because he's on a quest to find a powerful magical artifact that is said to be hidden in a far - off galaxy. Once he leaves, he has to deal with all kinds of strange new creatures and different forms of magic.
I recommend "The Last Cultivator on Earth". The protagonist of this novel not only sealed a passage to save the Earth, but also went to the Ming River to extradite his master, explore the lost past of the Nine Realms, and walk a path that defies the heavens. This novel combined elements of fantasy and oriental fantasy. It was very interesting and attractive. I hope you like my recommendation. Muah ~
In a 'Percy Jackson leaves earth' fanfic, he might end up in a whole new realm of gods and monsters. Maybe he discovers a parallel universe where the rules of the Greek gods are different. He could encounter new versions of his friends or enemies and have to learn new powers to survive.
" I Really Just Want to Go Back to Earth " was a sci-fi novel about interstellar civilization. It told the story of the protagonist who was accidentally sent to outer space and gradually adapted to life in outer space. However, he always missed Earth and finally decided to return to Earth. I hope you like this theme.
There's a chance he meets a group of nomadic magic - users. These are people who travel across the universe in search of new sources of magic. They could introduce Harry to different forms of magic that are not based on the traditional elements like fire, water, earth, and air that he's used to on Earth. Instead, they might use things like starlight or cosmic energy as a basis for their spells.
He might meet other inter - galactic beings. For example, some sort of space - faring demigods from a far - off galaxy. Or he could encounter powerful entities that are the rulers of other planets.
Dumbledore could also play a role even if Harry has left Earth. Maybe his spirit or some form of his magic reaches out to Harry from afar, guiding him on his journey and providing him with cryptic advice to face the challenges in outer - space - related magic.
Sure, She-Hulk is related to Hulk. Jennifer Walters, aka She-Hulk, got her powers because of a blood transfusion from her cousin Bruce Banner, who is Hulk. This connection is a key part of their storylines in the comics.
