Well, in many Harry Potter fanfictions, characters develop new magical powers by making pacts or connections with magical entities. For example, a character could make a deal with a powerful magical spirit. In return for some service, the spirit grants them a new power. Also, some characters develop new powers through self - discovery and meditation. By delving deep into their own magical cores and understanding their true nature, they can unlock powers that were previously hidden. Additionally, training with a very powerful and experienced wizard can also lead to the development of new magical powers as they learn new techniques and ways of using magic.
Fanfic writers often start with the existing magical concepts in the Harry Potter series and then expand on them. For example, if the original books mention apparition, a fanfic writer might develop a new form of apparition that allows the character to not only travel distances but also through different dimensions.
Powers can also be used to solve problems in the plot. A character with the power of flight might be able to reach a hidden location or rescue someone from a high - up place. Their power enables them to overcome obstacles that would otherwise be insurmountable. Moreover, powers can change relationships. If one character has a power that another needs, they may form an alliance. This can shift the power dynamics within the story and influence the overall direction of the plot.
New powers can completely change the direction of the plot. For instance, if a character has the power of instant teleportation across any distance, it can disrupt the usual modes of travel and conflict in the Harry Potter universe. It might make it easier to escape from danger or reach a place in time to prevent a disaster. This could also lead to new conflicts, as other characters might be jealous or afraid of this power.
Often, they start as underdogs. They are constantly put down because of their 'mudblood' status. But as the story progresses, they learn to be confident. They might study magic harder than others to prove themselves, like Hermione in the original series. And gradually, they gain respect from their peers.
In fanfiction, Harry Potter could share his magical powers through a special ritual. This ritual might involve gathering in a sacred place, like the Forbidden Forest or an ancient chamber in Hogwarts. He would need to call upon the elements and his own inner magic, and then transfer it to others through incantations and the use of magical artifacts such as a magic wand dipped in a potion of power - sharing.
The magic in Harry Potter has a more defined system with different branches like Transfiguration, Charms, and Potions. Each has its own set of rules and limitations. The gem powers in Steven Universe are more fluid and based on the gem's nature. In fanfiction, writers might create a situation where the strict rules of Harry Potter magic start to break down when exposed to the more fluid gem powers. For example, a spell that normally only affects living things in Harry Potter might start to work on gem constructs in the crossover fanfiction due to the influence of the Steven Universe world.
Some characters might develop their gambit powers through intense training. Just like in the original Naruto series where characters train hard to master their ninjutsu, in fanfiction, they could push their limits in special training regimens to unlock new aspects of their gambit powers.
In many of these fanfictions, the characters develop in response to the unique situations created by the god - like Harry. Let's say Ginny. She may have been just a love interest in the original series, but in the harem fanfiction, she might become a powerful ally in Harry's journey with his god - like powers. The characters also develop through facing challenges together. Maybe they have to fight against a new dark wizard who is after Harry's god - like powers. During these battles, they learn more about themselves and each other, and their relationships deepen. They might also develop new magical abilities or skills as a result of being part of Harry's world with his special powers.
Harry's character might also evolve differently. He could be more in tune with his emotions regarding Cho. In some fanfictions, he might open up to her about his fears and insecurities related to the prophecy and fighting Voldemort much earlier than in the original story.
The relationships between characters also play a huge role in development. For instance, if an elf inherits a position of power, the wizards around them may have to re - evaluate their relationships. Some might become jealous or try to undermine the elf, while others might support and learn from them. These complex relationship dynamics contribute to the overall character development in the fanfiction.
