Well, in Harry Potter slash time travel fanfiction, a common concept is the alteration of the wizarding genealogy. A character traveling through time could potentially change the family lines of various magical families. This could have a huge impact on the magical abilities and status of different characters. Also, it could lead to the discovery of new magical spells or artifacts that were lost in the original timeline.
One interesting concept is changing the outcome of major events in the Harry Potter series. For example, a time - traveling Harry could prevent Cedric Diggory's death in the Triwizard Tournament. Another concept might be exploring different relationships. He could go back in time and befriend Tom Riddle before he became Voldemort, potentially changing the course of the entire wizarding world's history. Also, the idea of time - travel magic being different than what we see in the original books, like more complex spells or restrictions.
One interesting concept is changing the past to prevent certain tragedies in the wizarding world. For example, a fanfic might explore what would happen if someone went back in time to stop Voldemort's rise to power from the very beginning. Another concept could be using time travel to rescue characters who died in the original series, like Sirius Black. And sometimes, it's about exploring the different time - turning devices and their rules in more depth than what was shown in the books.
In 'harry potter hulk slash fanfiction', a cool concept might be the characters' crossovers in their respective universes. Imagine Harry Potter and his friends visiting the world where the Hulk exists. They could learn about different forms of power and how to use it, and perhaps they could teach the Hulk's allies some magic tricks in return.
One interesting concept could be a hybrid creature. For example, a mix between a hippogriff and a phoenix. In fanfiction, this could possess the majestic flight of a phoenix and the proud and somewhat dangerous nature of a hippogriff. It could be a symbol of new beginnings and also a powerful protector in the wizarding world created within the fanfiction.
Well, in Harry Potter Batman slash fanfiction, a cool concept might be the fusion of their respective technologies and magic. For instance, the Bat - gadgets could be enchanted with magic from the Harry Potter universe.

It could be a dark wizard who has made a pact with Gotham's criminal underworld.

Well, in some Harry Potter alternate universe slash fanfiction, there are concepts like magic being used in completely new ways. For instance, instead of using wands for all spells, some fanfics might explore the idea of using just a thought or a gesture. Also, the idea of different family dynamics can be really interesting. Like if Harry had been adopted by the Malfoys or something, how would that change his character and the whole story? It could lead to a whole new set of adventures and interactions with other characters.
One interesting concept could be the crossover of magic systems. In such fanfiction, we might see how the wands and spells from Harry Potter interact with the demigod powers in Percy Jackson. For example, a scenario where a demigod tries to learn a simple spell like 'Lumos' and has an unexpected reaction due to their divine heritage. Another concept could be the interaction between the characters. Picture Harry Potter and Percy Jackson teaming up to face a common enemy that combines the threats from both their worlds, like a dark wizard who has also made a pact with a powerful Greek monster.

Also, the idea of Quidditch being played with some Bleach - inspired elements, like using spiritual energy to boost broom speed or adding new types of balls with unique powers.
Another concept might be the cultural clash. Harry is from a world of wizards with their own traditions and social structures, while Anakin comes from a galaxy far, far away with very different norms. Their interactions could lead to some really unique storylines, like Anakin being confused by Hogwarts' house system or Harry being astonished by the technology in the Star Wars universe.
