They can start by checking out popular fanfiction websites like Archive of Our Own. There are usually tags and search filters that can help them narrow down to AOT fanfiction. They can also look for works that have a high number of hits or positive reviews from other readers.
First, the characters. You could have Deku from MHA interacting with Eren from AOT. Maybe Deku is intrigued by Eren's determination and Eren is in awe of Deku's unique quirk. Second, the settings. Incorporate both the UA Academy from MHA and the walls of AOT. For example, the Scouts could visit UA to learn about modern combat training. Third, the themes. Combine the heroism theme from MHA with the survival and freedom themes of AOT. This would create a rich and complex story.
Another aspect is the community aspect. MHA fans who watch AOT fanfiction may join in on discussions with other fans who also enjoy this crossover of interests. They can exchange ideas about which AOT fanfiction plots would be most exciting if the MHA characters were involved, and this can create a more diverse and engaging fan community.
It's fairly common. Fans often look for more content related to their favorite shows. Since 'Attack on Titan' has a large and passionate fan base, there are a lot of fanfics available. 'Aot' fans might watch (read) these fanfics to explore different scenarios that the official story didn't cover. For example, they might want to see how a certain character would react in a different situation or what would happen if a major plot event had a different outcome.
In most cases, it is legal to watch fanfiction as long as it adheres to certain rules. Fanfiction is a form of creative expression by fans. However, if it involves copyright infringement, such as using excessive amounts of original copyrighted material without permission, it could be an issue.
There are also some YouTube channels that might do readings or interpretations of AoT fanfiction. However, these might be less common and you need to search carefully. Additionally, some fan - run websites dedicated to AoT might host fanfiction that can be read and sometimes even listened to if they offer such features.
There could be various fanfictions. Maybe some that focus on alternative endings, like ones where certain characters survive who didn't in the original. For example, a fanfiction where Erwin survives and leads the Scouts in a different way.
One way is to check on popular fanfiction websites. Look for ones with high ratings and a lot of reviews. For example, Archive of Our Own (AO3) has a large collection of AOT fanfictions. You can search for the most popular ones there.
It depends on the nature of the fan - created work. In some cases, it's a fun and normal way to explore the MHA universe from a different perspective. For example, if the fan work is a comical or satirical take on the series, having MHA characters watch fanfiction can be a great source of humor. However, in more serious or canon - adherent fan works, it might seem out of place. But overall, in the wide range of fan - created works, it's a fairly common and accepted concept.
