You can start by looking on fanfiction websites such as Archive of Our Own (AO3). It has a large collection of fanfictions from various fandoms, including ones that combine Harry Potter and Hunter x Hunter. Another option is FanFiction.net. However, the quality can vary greatly on both sites, so you may need to read through some summaries and reviews to find the really good ones.
Some Tumblr blogs are dedicated to sharing and discussing fanfictions. You can search for tags related to Harry Potter and Hunter x Hunter fanfiction on Tumblr. There are also some smaller, more niche fanfiction communities on Reddit. For example, there might be a subreddit specifically for crossover fanfictions where you can find some hidden gems.
Check out Wattpad as well. While it's known more for original stories, there are also a good number of fanfictions. Just be aware that the content on Wattpad may not be as well - moderated as on AO3 or FanFiction.net. But if you're patient and do some digging, you might come across some great Harry Potter and Hunter x Hunter fanfictions.
