The musical style of Hamilton can be incorporated by having the characters break into song - like numbers. For instance, Harry could sing about his quest to defeat Voldemort in a rap - like style similar to how Hamilton rapped about his life and goals. The lyrics could be filled with references to spells, magical creatures, and the battle between good and evil in the wizarding world.
A pet could have unique powers that are useful in both worlds. Let's say a pet has the power of invisibility in the Harry Potter world. In the RWBY world, this power could be used to sneak up on Grimm or avoid detection by enemies. The pet could also form bonds with characters from both universes. For example, it could befriend Ruby and also get along with Harry, and through these relationships, bring the two groups of characters closer together.
The Imperial Remnant could be incorporated by having them arrive in the Harry Potter universe through a magical - technological rift. They might then try to take over the wizarding world, seeing it as a new territory to control.
In a crossover fanfiction, the lightning wave could be a result of a magical experiment gone wrong. A Hogwarts student, perhaps Hermione, is researching ancient magic and accidentally creates a portal that sucks in Naruto. Together, they figure out that Naruto's lightning - style jutsu can be enhanced with Hermione's knowledge of magic, creating a new and more powerful lightning wave. This lightning wave could then be used to fight off dark forces from both the Naruto and Harry Potter universes, like the Death Eaters and the Akatsuki.
First, blend the settings. Combine the high school environment of High School Musical with the magical elements of Harry Potter. Then, re - imagine the characters. Give them traits from both universes. For example, make Troy a Quidditch star who also loves to sing. Next, create a plot that involves both high school - like drama and magical adventures. Maybe there's a competition that is both a musical and a magical duel. Finally, don't forget to add some humor and heart, just like in the original works.
One way is through the wizarding economy. For example, the Weasley twins' joke shop, Weasleys' Wizard Wheezes. Fanfiction could expand on the business side of it, like how they manage inventory. They might have to source ingredients for their magical pranks from different wizarding markets. Another aspect could be marketing. How do they promote their products? They could use magical means like enchanted flyers that follow potential customers. Also, they need to deal with competition, perhaps from other prank - selling shops in Diagon Alley.
Another way is to have the kitten be a gift from a mysterious character. Maybe Dumbledore gives a kitten to Harry as a way to help him deal with the stress of fighting Voldemort. The kitten could have some sort of calming magic that helps Harry stay focused and centered during difficult times. This would add an interesting dynamic to their relationship and also give the story a new angle to explore.
One way is to have a crossover where the technology of transformers somehow enters the wizarding world. For example, perhaps a magical experiment gone wrong causes a transformer to appear in Hogwarts. The students might be both amazed and a bit scared at this mechanical being. It could also be that a wizard or witch discovers a way to use transformer parts to enhance their magic, like using a transformer's energy source to power a particularly large and complex spell.
One way a minotaur could be incorporated in Harry Potter fanfiction is as a new magical creature in the Forbidden Forest. It could be a guardian of some long - lost magic or a hidden area within the forest.
One idea could be to have the characters from Hamilton attend Hogwarts. Alexander Hamilton could be a brilliant Muggle - born wizard who uses his quick thinking and ambition to excel in his studies, much like he did in the original Hamilton story. He might even start a new club at Hogwarts, similar to how he was always creating and leading in his own world.
His music style, which is often bold and energetic, could be used as a source of magical power. For example, in a fanfic, a character might use the rhythm of Adam Lambert's song to cast a spell faster or more powerfully.
