A fleet of magical ships is also a possibility. These ships could be made of magical wood and have various enchantments. They might be able to travel between different magical dimensions or through dangerous magical waters. Maybe they are crewed by a mix of wizards, magical creatures, and even house - elves, all under Harry Potter's leadership in the fanfiction world.
Well, in fanfiction, just about anything can happen. Harry Potter having a fleet is not out of the question. It could be part of a large - scale war scenario where he needs a fleet to transport troops or magical artifacts. Or it could be for a more peaceful exploration purpose, like discovering new magical islands. Writers can really let their imaginations run wild with such concepts in fanfiction.
Well, perhaps the characters from Harry Potter are magically transported to the realm of Fod where they encounter the fleet. Harry and his friends could form alliances with the Fodians who own the fleet. Together, they face challenges like dealing with strange Fodian magic and creatures, all while trying to find a way back home. Maybe they also discover that the Dark Lord Voldemort has some connection to an evil force in Fod, and they have to defeat both threats.
Well, perhaps the 'Fleet of Fog' enters the wizarding world and the wizards initially mistake them for some new kind of dark magic creatures. Harry and his friends then have to figure out what they are and find a way to either make peace or drive them away. The wizards could use their magic to try and understand the technology of the Fleet of Fog, like Ron trying to figure out how their engines work with a simple 'Engorgio' spell on some of the parts to see what happens.
He could go on adventures to discover hidden vaults within Gringotts. Maybe there are vaults that have been lost for centuries, filled with ancient and powerful magical artifacts. Harry could search for these vaults, facing various traps and puzzles along the way, similar to the challenges he faced in the Philosopher's Stone.
I think Neville could be an interesting main character in this crossover. He has grown so much in the Harry Potter series, and his knowledge of plants could be used in some unique ways against the Fleet of Fog. For example, he could use some magical plants to either hide Hogwarts from the Fleet of Fog's sensors or use them as a form of defense. From the Fleet of Fog, a young and curious engineer could be a main character. They would be fascinated by the magic and would try to figure out how to incorporate it into their technology. Ginny Weasley could also be a main character, with her strong will and magical abilities.
They could go on an adventure to find a missing magical artifact that has fallen into the Muggle world. Gibbs' skills in tracking and Harry's knowledge of magic could be combined to track down the artifact before it causes any harm.
It could be a magical sailing ship. Maybe it has enchanted sails that can catch the wind of magic and sail across different magical realms. Or it could be a small, personal ship that he uses to explore hidden corners of Hogwarts lake.
Her magic could also include the ability to control the elements. So during a game, she could create a small gust of wind to direct the ball's path or make the floor slippery for the opposing team by using a water - based spell. This would add an interesting dynamic to the basketball matches.
He could be really outgoing. Maybe he's the type who makes friends easily and is always the life of the party at Hogwarts. Unlike Harry who was a bit more reserved at times, the younger brother could be constantly getting into adventures and dragging Harry along with him.
Harry could have adventures where he tries to help his parents' ghosts pass on to the afterlife properly. This would involve solving mysteries about their untimely deaths. Along the way, he'd meet other ghosts with their own stories, and they could join him on his quest. He might also find ancient spells that can interact with the ghostly world more fully during these adventures.
