Some fanfics also focus on the psychological aspect of their relationship. Reiner and Bertholdt both have complex personalities and backstories. Fanfics might explore how they understand and support each other on a psychological level, perhaps dealing with their inner demons together.
Fanfiction.net is also a great place to look. There are many 'Attack on Titan' fanfics there. Just type in 'Reiner x Bertholdt' in the search bar and browse through the results. However, the quality may vary, so you might need to read a few to find the really good ones.
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.
Well, in my opinion, Star Wars has the edge in fanfiction for this 'Warhammer 40k vs Star Wars' comparison. The concept of the Force is just so fascinating and offers a lot of room for creative exploration in fan stories. Also, the iconic characters like Luke Skywalker and Darth Vader are well - known and loved, which makes it easier for fans to write engaging stories. Whereas Warhammer 40k can be a bit more complex and intimidating for new writers in the fanfiction world.
Both Warcraft and Warhammer Fantasy have their own strengths when it comes to storytelling. Warcraft offers a story that is very much centered around heroism and the fight against great evil. The story arcs of many of its heroes are quite inspiring. On the other hand, Warhammer Fantasy has a more sprawling and detailed world. The stories are often intertwined with the history and mythology of the various races. It's really hard to say which one has a better story. If you like a more heroic - focused and fast - paced story, Warcraft might be better for you. But if you prefer a darker, more complex world with a lot of historical depth, Warhammer Fantasy could be the one.
Reiner did die in the manga. His death was a result of a series of events and conflicts that had been building up throughout the storyline. It had a major impact on the plot and the other characters.
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.
It's really hard to say. In Warhammer 40k, there are extremely powerful Space Marines with advanced technology and psychic powers. However, in Star Wars, the Force gives Jedi and Sith incredible abilities. If it's a large - scale battle, the Imperium of Man in Warhammer 40k has a huge number of troops. But the Star Wars galaxy has the Death Star which can destroy planets. So it depends on the specific scenario written in the fanfic.
