There's 'A Different Path' which imagines a scenario where Grindelwald and Newt have to work together against a common, greater evil. This fic is great because it really builds on their characters and how they might interact in a situation outside of the normal canon events. It has some really interesting dialogue exchanges that fans of the pairing will enjoy.
A great characteristic is the exploration of their relationship's complexity. Since Grindelwald is a dark wizard and Newt is more on the side of good, the fic should dig deep into how they overcome or at least deal with these differences. It could also have a unique take on the wizarding world. Like, it might introduce new magical concepts or places that add to the overall atmosphere of the story. And of course, good writing in terms of grammar and style is essential.
Dialogue is important. Write dialogue that reflects their personalities. Newt might stutter a bit when he's nervous around Grindelwald, and Grindelwald might use his charisma and charm to manipulate or persuade Newt. Add some conflict in their relationship, not just external threats but also internal ones like their different beliefs. And make sure to end the fanfic in a satisfying way, whether it's a happy ending or a bittersweet one that leaves the reader thinking.
There are also some dedicated Harry Potter and Fantastic Beasts fanfic communities on Reddit. Subreddits like r/FantasticBeastsFanfic might have threads or posts about Newt x Grindelwald fanfics. Members often recommend their favorite stories, and you can also ask for specific types of fanfics in those communities, like ones with a particular plotline or writing style.
Thomas is a great character to pair Newt with. Their friendship in the original story is strong and in fanfiction, it can be developed into something deeper like a brotherly bond that overcomes all the challenges in the Maze. Another good one is Minho. Minho's tough - guy attitude and Newt's more level - headed nature can create interesting dynamics.
Dumbledore would be a great addition. Since he has a long history with Grindelwald, his presence could add a lot of depth and backstory to the fanfiction. Another good character could be Hermione. Her intelligence and knowledge of magic could help Harry in his encounters with Grindelwald. Also, Newt Scamander could be included. Given his experience with magical creatures and his own adventures in the wizarding world, he might be able to offer unique perspectives and assistance.
At first, it might be a relationship based on Grindelwald's self - serving motives. He sees Harry as a tool. But as they spend time together, there could be moments of mutual understanding. Harry might start to see Grindelwald not just as a villain but as someone with complex ideas.
Aberforth Dumbledore can be a very important character in these fanfictions. He is Albus Dumbledore's brother and has his own feelings and history related to his brother and Grindelwald. He might be the one who tries to bring his brother back from the brink when Dumbledore is too involved with Grindelwald. Also, Leta Lestrange could be popular. Her family's dark reputation and her own complex relationship with Newt and the wizarding world in general can add an extra layer of drama to the fanfictions involving Dumbledore and Grindelwald.
At first, it would be really awkward. They are from different worlds in a way. Harry is more into fighting dark wizards, and Newt is all about magical creatures. But as they are forced to be together due to the accidental marriage, they might start to respect each other's passions more. They could learn from each other, like Harry learning about magical creatures from Newt, and Newt learning some combat skills from Harry.
