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.
Well, it depends on what you consider 'good'. Some people might like the ones that focus on Harry's internal struggle while being trained by Grindelwald. For example, there could be fanfictions where Harry has to decide whether to follow Grindelwald's teachings or stick to his own values. However, not all such fanfictions are well - written. Some might have plot holes or out - of - character moments.
Common themes in Grindelwald fanfiction include his rise to power. Many stories detail how he built his influence and following. The idea of his ideology is also a big theme. His beliefs about the superiority of wizards and how he wants to reshape the wizarding world are explored. Additionally, the theme of his past and how it shaped him, such as his childhood experiences or his early encounters with magic, are often part of these fanfictions.
One great 'Harry Grindelwald Fanfiction' is 'The Lost Tales of Grindelwald'. It delves deep into his backstory and his early days at Durmstrang. The character development in it is quite engaging.
Yes. In some fanfictions, the author might create an interesting plot where Harry Potter is shown as a fan of Grindelwald for various reasons. Maybe it's due to Grindelwald's powerful magic that Harry is intrigued by, or perhaps the author wants to explore a more complex relationship between the two characters outside of the original canon.
I think the 'Harry Potter' companion books could potentially contain Grindelwald's story. They often expand on the wizarding world's history and characters.
