The fanfiction should bring something new to the table. It could be a new interpretation of magic, a different view on the relationships between characters, or an exploration of uncharted areas in the 'Harry Potter' lore. It should make readers see the familiar world of Harry Potter in a whole new light, which is what makes it powerful.
Character development is key. The characters from the 'Harry Potter' world should retain their core traits while also evolving in the new context of the crossover. If Hermione is in a crossover with a steampunk world, she should still be the intelligent, inquisitive character but also adapt to the new technological and cultural aspects of that world.
In fanfiction, Harry Potter might be made a more powerful wizard through various means. For example, he could have access to new spells or magical artifacts that enhance his powers. Maybe he has a different kind of magical training that unlocks hidden potential within him.
In fanfiction, it could be special genetic mutations. For instance, a mutation that supercharges his magical core, allowing him to cast spells with much greater power and efficiency than normal wizards. This would make him stand out as a powerful mutant.
A powerful and intelligent Harry Potter fanfiction often has well - developed characters. For example, if it gives more depth to minor characters like Neville Longbottom, showing his growth in power and intelligence in a new way. It also might have complex and original plotlines that expand on the existing Harry Potter world without contradicting the original lore.
Powerful magic skills are a key factor. This includes being able to cast complex spells accurately and quickly. For example, the Patronus charm is a difficult spell, and a wizard who can easily cast a powerful Patronus is usually seen as strong. Also, knowledge of different branches of magic like Transfiguration, Charms, and Potions plays a big role.
Knowledge of magic is key. A character who has delved deep into ancient magic texts and understands magic on a theoretical level can be very powerful. They can use this knowledge to solve problems or create new magic. For instance, a character might discover a long - lost spell in an old grimoire and use it to defeat a powerful enemy. Also, connections and alliances can contribute to power. A character who has the loyalty of a group of powerful wizards or magical creatures can be more powerful. For example, a character who has befriended a dragon or a group of centaurs has more resources at their disposal in a fight or in a difficult situation.
Well, one factor is a powerful and confident version of Harry. For example, if he has some new and extraordinary magical abilities that set him apart. Like in some fics where he can control all the elements, that's really badass. Another aspect could be the way he stands up to the villains. If he doesn't wait for them to make the first move but actively hunts them down.
Well, first of all, it's the development of Harry's character. If he's powerful, it should be shown in a believable way. For example, if he has new magic, there should be a good explanation for it. Also, the plot should be engaging. A powerful Harry should face new and exciting challenges. In some great fanfics, Harry's power makes him a target, and he has to use his wits and strength to overcome enemies.
Often, it's the creative ideas of the fanfiction writers. They might give him this power due to some magical accident or a hidden heritage. For example, they could write that he inherits telepathic abilities from a long - lost ancestor.
It's unique because it gives a fresh perspective on the Animagus ability. In regular Harry Potter, we know the basic rules and uses of being an Animagus. But in a crossover fanfiction, the Animagus ability can be reimagined in different settings. Say, an Animagus might have to hide their form in a world where magic is not as accepted as in the Harry Potter world. This creates a whole new set of challenges and plot twists.
Character development is key too. When characters from both series interact, it should feel natural. For instance, if Tony Stark were to meet Hermione Granger, their conversations should be engaging, with each character staying true to their original personalities. Stark might be impressed by Hermione's intelligence and magic, while Hermione could be intrigued by Stark's technological genius. Good crossovers also explore how the characters grow and change as a result of interacting with a completely different world and set of characters.
