Well, in some fanfics, time travel is more complex. There might be special portals or ancient magic that allows for time travel. For instance, there could be a hidden chamber in Hogwarts that holds the key to traveling through time. And the consequences of time travel can range from minor changes in the present to completely rewriting the future of the wizarding world. Sometimes, characters find that they can't change certain events because they are 'fixed points' in time, much like in some theories of time travel in other science - fiction and fantasy works.
In most 'Harry Potter Time Travel Founders Fanfic', time travel often works through magical artifacts or spells. For example, a powerful time - turning charm might be used. Sometimes, it could be an enchanted object like a special mirror or a locket that has the ability to transport a character back to the founders' era.
In a time - travel Bellatrix fanfic, she might go back to the time when she was first introduced to the Dark Arts. This could show a different side of her, perhaps a more innocent - looking but still dark - inclined Bellatrix. She could interact with younger versions of other Death Eaters and form different alliances that change the course of the future in the wizarding world.
In some Hermione time travel fanfics, she might use time - turners in a more extreme way than in the original books. She could end up in a different era altogether, like the time of the founders of Hogwarts. This would open up a whole new world of magic and mystery for her to explore.
There's also 'Back Through Time with Harry and Luna'. In this fanfic, their time - traveling adventures lead them to discover secrets about their families that were long forgotten. It has a lot of heart - warming moments between the two characters.
I really liked 'The Time - Traveling Duo: Harry and Susan'. In this fanfic, they travel to different points in wizarding history. It's fascinating to see how they use their modern knowledge to deal with the situations in the past. There are also some great character developments along the way.
Another amazing one is 'Back to the Beginning'. This fanfic takes the idea of time - travel and uses it to explore the early days of Hogwarts and the relationships between the founders. It's filled with a lot of mystery and intrigue as the main character tries to figure out how to use their time - traveling ability to make things right in the past without completely disrupting the present.
One great 'Harry Potter Time Travel Fanfic' is 'All the Wrong Choices'. It offers a really interesting take on how time travel could change the course of the original story.
There's a fanfic called 'Time's Twist'. It's amazing because it not only involves time travel but also delves deep into the relationships between different characters. For example, it shows how Harry's knowledge from the future affects his relationships with his parents and the Marauders. It also has some great action scenes that are intertwined with the time - travel elements.
Regarding the Iggy fanfic involving Harry time travel and James' brother, one possible plot could be that Harry accidentally time travels to a period when James' brother was in a difficult situation. Harry, using his knowledge from the future, tries to help him out. Along the way, they might discover some unique magical abilities or artifacts that were previously unknown. This could also lead to a deeper understanding of the Potter family history and how it has influenced the wizarding world as a whole.
