No, it's not possible in the literal sense. Attack on Titan is a fictional story, not a sentient being with the ability to read or watch fan - created content. Fanfics exist in our world for fans to explore different ideas about the Attack on Titan universe.
Well, it's a really strange concept as Attack on Titan is a fictional entity and can't actually 'watch' a fanfic. But if we were to be creative, maybe it would be like the characters in the series are observing an alternate version of their own story. They might be shocked, amused or even inspired by the different plotlines and characterizations in the fanfic.
Well, among the notable characters is Cardina Baumeister. He plays a role in the power dynamics within the story. Then there's also Marlowe. He has his own set of goals and motivations that contribute to the overall narrative of 'Attack on Titan Before the Fall' light novel.
One of the main themes is the struggle for survival. Just like in the main 'Attack on Titan' series, characters in 'Before the Fall' face the constant threat of Titans. Another theme is the exploration of human nature. We see different characters react in various ways to the extreme situation of living in a world with Titans. Some show great courage, while others are consumed by fear.
No. 'Attack on Titan' is a fictional story created by Hajime Isayama. It's set in a fictional world with its own unique rules, characters, and plotlines that are products of the author's imagination.
The Attack on Titan manga is indeed done. It wrapped up, bringing an end to a popular and highly engaging series that captured the hearts of many readers.
