What could be the plot of 'Harry Potter builds an army fanfiction'?

Obviously, his friends Ron and Hermione would be among the first to join. Neville could also be a key member, as he has shown great courage. Then there might be the members of Dumbledore's Army who are still at Hogwarts. The Weasley twins could also be part of it, using their unique magical inventions to give the army an edge in battle.

Well, perhaps Harry uses his magic to shape the planet. He might create unique magical creatures and ecosystems. For example, he could make a forest where the trees are made of living fire that doesn't burn but gives warmth and light.

Maybe Harry builds a magical trunk that has special compartments for his school supplies, like a self - organizing quill holder and a spell - protected space for his invisibility cloak. It could also have a hidden entrance to a small room where he can study privately without being disturbed by his roommates.

Maybe Harry Potter builds the fortress to protect Hogwarts from a new dark threat. He could use his magic skills and the knowledge he has gained over the years to construct an impenetrable fortress with magical defenses like anti - apparition wards and powerful spells.

Maybe Harry uses magic to create an island as a secret hideout from the Dark forces. He could make it full of magical creatures and plants that he discovers during his adventures.

The plot could involve Harry building the ship with the help of his friends. They could all contribute their skills. For example, Hermione could use her vast knowledge of magic theory to ensure the ship's construction is perfect, while Ron could offer his practical skills. They might be building the ship to escape from some new dark force that has emerged in the wizarding world. Harry's ship would then be their means of getting away and finding a new place to start over. It could also be a ship that has special magical properties, like being able to fly or travel through time.

Maybe Harry Potter builds a home in a hidden forest near Hogwarts. He could use magic to create a cozy cottage with a fireplace that always has a warm fire burning, and rooms filled with memories of his friends and adventures.

Well, perhaps Harry Potter discovers some ancient magic that has the potential to create a stargate. He might use his knowledge from Hogwarts and the wizarding world to assemble the components of the stargate. Maybe he's on a quest to find a new form of magic or a lost spell that is only accessible through the stargate.

The plot could involve Harry Potter building a town that is a blend of the Muggle and magical worlds. He could build schools that teach both magic and Muggle subjects, houses that have both magical and non - magical features. He wants to create a place where wizards and Muggles can co - exist and learn from each other. This would be a revolutionary idea in the Harry Potter universe and would attract all kinds of people, leading to many adventures and challenges along the way.

The plot could involve Harry using his knowledge of spells and potions to create a unique starship. He could also recruit his wizard friends to help him. For example, Hermione could use her vast knowledge to research the best magical elements to incorporate into the ship's design, while Ron could provide his loyalty and physical strength for the more labor - intensive parts of the construction. And they might face challenges from the wizarding world, like the Ministry of Magic trying to stop them for fear of revealing magic to the Muggle world through their starship adventure.
