He may discover a hidden magical society in America that has been isolated from the rest of the world. This society could have its own set of rules and magic that is completely different from what he's used to. Harry's exploration of this society would be filled with challenges and revelations as he tries to adapt and understand their ways.
He might encounter new magical creatures. For example, he could come across the Thunderbird in America which is a very powerful and majestic creature. This encounter could lead to a whole new adventure as he tries to understand its nature and how it relates to American magic.
There could be a run - in with the American wizarding law enforcement. Maybe he doesn't follow all the proper procedures when entering the country, and he has to deal with the consequences. This could involve making new allies within the American wizarding community who help him out of the mess.
They could encounter new magical creatures. For example, in other parts of the world, there might be undiscovered or rare magical beasts that they have never seen before in England. This would be a whole new experience for them to learn about these creatures and how to interact with them.
One possibility is that they team up to fight against the remnants of the dark forces that are still lurking in the shadows. Harry's courage and Snape's knowledge would make them a formidable duo. They might travel to far - flung places in the wizarding world, from hidden valleys to enchanted islands, in search of these threats and ways to eliminate them. And along the way, they would have to learn to trust each other more and more, which would be a huge character development for both of them. This would also expose them to different magical cultures and practices that they hadn't encountered before, adding more depth to their own magical abilities.
They might also embark on a diplomatic mission. With the wizarding world in a state of flux after the war, different magical communities need to be brought together. Harry, as a well - known figure, and Ginny, as a respected witch, could visit other wizarding countries to establish alliances and promote cultural exchange. This would involve meeting different magical customs, dealing with political intrigue, and making new friends and enemies along the way.
One adventure could be exploring uncharted territories in search of new forms of magic or new species. This would be a way for them to expand their knowledge and contribute to the growth and development of their world. They might face many challenges along the way, like dangerous terrains and hostile creatures, but their combined skills would help them overcome these obstacles.
They could go on a journey to explore the unknown lands that were previously inaccessible during the war. Maybe there are new magical creatures or ancient ruins waiting to be discovered.
In the fanfiction, Harry could meet Native American wizards or witches who have a deep connection to the land and ancient magic. Their magic might be based on nature and spirits in a way that is very different from what Harry is used to in Britain. He may also meet some Muggle - born American wizards who have a different perspective on being part of the wizarding world, having grown up in a different cultural and social environment compared to Harry.
Perhaps they meet a group of outcasts who have their own unique abilities. These outcasts could teach Percy and Annabeth new fighting techniques or ways to use their powers more effectively. They might join forces with them to take on a common enemy that is threatening both the outcasts and the world they come from.
They could go on a mission to track down remaining threats from the war. There might be rogue ninjas or hidden enemy bases. Naruto's combat skills and Temari's strategic mind would make them a great team.
In fanfiction, Naruto and Sasuke could have an adventure where they face a new threat that emerges after the war. This threat could be a powerful and unknown enemy from a far - off land. They would have to combine their skills, Naruto's Rasengan and Sasuke's Chidori, and their newfound understanding of each other to defeat this enemy. Along the way, they would also encounter various interesting characters who help or hinder their journey.
One reason could be the trauma he endured during the war. He witnessed so much death and destruction that he might feel the need to escape it all. Maybe he wants to get away from the constant reminders of his friends who didn't make it.
