One example could be that the positive battery is used to power a portal. In the fanfic, this portal allows the Avengers to travel to the wizarding world of Harry Potter. It's a positive battery because it's a source of energy that enables a positive connection between the two universes, leading to new adventures and the ability to fight common threats together.
In a more literal sense, if we think about a positive battery in a fanfic, it could be a new invention. Maybe a wizard in the Harry Potter world teams up with Tony Stark. They create a positive battery that uses both magic and technology. This battery could power a device that can nullify dark magic and the weapons of villains from both universes.
Well, he could bring his magic skills to the team. Maybe he could use spells to enhance the Avengers' weapons or defenses. For example, he could put a protection charm on Iron Man's suit to make it even more resistant to attacks.
Another theme is the teamwork aspect. Both Harry Potter and the Avengers rely on teamwork. Fanfics often explore how the characters from the two universes would work together, like Hermione and Bruce Banner collaborating on some scientific - magical research.
First, you need to understand the characters well. Know their personalities, powers, and goals. For example, Thor is a powerful Asgardian with his hammer (or axe in Endgame), and Harry Potter is a young wizard with a strong sense of justice. Then, think of a plot that can bring these two universes together. It could be a crossover of villains, like Loki and Voldemort teaming up.
In some fanfics, the unexpected might be that Harry Potter himself loses his magic for a while. This turns the whole dynamic upside down as he has to rely on his friends and non - magical skills. It's a new take on his character and creates a lot of room for different plot developments. Also, there could be a fanfic where the Weasley twins' pranks go horribly wrong in an unexpected way, like accidentally releasing a dangerous magical creature within Hogwarts.
In some fanfics, Ginny Weasley shows great courage and cunning. For instance, she might have the courage to explore the Forbidden Forest on her own for a particular quest. And her cunning is shown when she uses her knowledge of the forest's creatures and magic to her advantage. She could set up clever traps or distractions to avoid dangerous creatures while still making progress towards her goal. This kind of portrayal of Ginny in fanfic not only gives her more agency but also shows how the themes of courage and cunning can be applied to different characters in the Harry Potter universe.
In the world of fanfic, it's a complex matter. From one perspective, using Crucio goes against Harry Potter's moral code in the original series. He is a hero who stands against the Dark Arts. However, in fanfic, authors might explore 'what - if' scenarios. But still, it's not an ethical act as Crucio is an unforgivable curse that causes extreme pain.
In a fanfic, Harry Potter could enter the Avengers' story through a magical portal. Once there, he could use his magic to complement the Avengers' skills. For example, his ability to communicate with snakes could be useful if they encounter snake - like villains. His experience with horcruxes might also give him insights into dealing with powerful and hard - to - destroy enemies in the Avengers' world. His wand could be a unique weapon in their battles, and his ability to perform complex spells could turn the tide in difficult situations.
One possible fanfic could be about a wizard from the Harry Potter world accidentally stumbling into the Marvel universe. The wizard discovers the Infinity Stones and realizes their immense power. He teams up with the Avengers to protect the Stones from a dark wizard who wants to use them to conquer both universes. The story could involve the wizard using his magic in unique ways to help the Avengers in battles and the Avengers teaching the wizard about their world.
Another well - liked pairing is Thor and Hagrid. Thor, being a god, and Hagrid, with his love for magical creatures, could have some really fun adventures together. Maybe Thor would be intrigued by the magical creatures in the Harry Potter world and Hagrid would be in awe of Thor's godly powers.
