Well, it could lead to a really wild and fast ride. The cart might zoom through the Hogwarts corridors at an incredible speed, causing chaos among the students and teachers. Maybe it would even be able to fly out of the castle and into the wizarding world beyond.
Hermione would probably be shocked and immediately start worrying about the safety and the rules being broken. Ron, on the other hand, might be both amazed and a bit envious, thinking it's a really cool idea. Professor McGonagall would be very disapproving and try to stop it right away.
He might be quite amused. Fanfics often contain different interpretations of the characters and the wizarding world. He could find some creative ideas in them that he never thought of before, like unique magical spells or new backstories for his friends.
In such a fanfic, Harry might experience extreme pain and weakness. His friends would likely be in a panic. Hermione would probably immediately start looking for antidotes in the library or with her vast knowledge of potions. Ron would be by Harry's side, trying to keep him conscious and reassuring him.
Well, he'd probably become super powerful. The symbiote could enhance his magic skills and give him some cool physical abilities like super strength and agility. Maybe he could use it to fight the Dark Arts in a whole new way.
If Harry Potter moves to America in a fanfic, he'd likely encounter new friends and foes. American wizards might have different attitudes towards his fame. Some might be in awe, while others might be more skeptical. He could also get involved in American magical politics, which could be very different from the British Ministry of Magic's operations. And his magic skills might be seen in a new light, as the American magical world may value different types of magic.
In such a fanfic, Harry might be tortured for information about the Order of the Phoenix. Voldemort could try to turn Harry to the dark side, using his powerful magic to break Harry's will.
Well, if Harry Potter started to draw fanfic, it would be quite a departure from his normal activities. He would likely draw fanfic based on his memories and experiences. Maybe he'd draw about his first time on a broomstick, or his first encounter with a Dementor. His drawings could bring a new perspective to the events that we already know from the books. It could also be a form of therapy for him, as he has been through so much trauma. His fanfic drawings might even end up in the Hogwarts library, becoming a new genre of magical literature. But he would have to deal with the reactions of his friends and teachers. Some might be supportive, while others might think it's a waste of time considering all the other important things going on in the wizarding world.
If Harry Potter was raised by a Creepypasta fanfic, his upbringing would be far from the typical Hogwarts - bound experience. For starters, the stories and bedtime tales he'd hear would be filled with grotesque and nightmarish content. This could lead to him having a very different perception of the magical world. Instead of seeing Hogwarts as a place of wonder and learning, he might view it with suspicion, thinking there are hidden, malevolent forces everywhere. His friendships would also be affected. He might attract those who are into the darker side of magic, and repel those with more traditional values. His magical abilities could develop in an unorthodox way too, perhaps focusing more on defensive and dark - arts - like spells out of a sense of self - preservation.
He'd probably be a bit of an enigma at Hogwarts. Gandalf has his own moral code and wisdom from Middle - earth. This could either clash or blend well with Hogwarts' values. Maybe he'd become a mentor to Harry and his friends, guiding them with his centuries - old knowledge.
If Harry Potter were in Westeros, he could bring some of his own unique magic skills. For example, his ability to fight dementors could be useful against some of the dark forces in Westeros. However, he'd also face challenges. The society in Westeros is based on a feudal system, and he'd need to find his place in it. Maybe he'd join one of the houses and use his magic to help them in battles or in solving internal problems.
