One common theme is survival. Just like in Attack on Titan, the characters in these fanfics often have to fight for their lives against the Titans. For example, in many fanfics, the Hetalia characters use their unique skills to try and survive in this dangerous world.
Sure. 'A Titan's World in Hetalia' is a great one. It combines the intense and dark atmosphere of Attack on Titan with the unique character concepts from Hetalia in an interesting way.
Well, a cool concept could be the power dynamics. In Hetalia, each nation has its own strengths and weaknesses. When combined with the world of Attack on Titan, those strengths and weaknesses could play out in interesting ways. For instance, a nation known for its military strategy in Hetalia might come up with new battle plans against the Titans. Also, the idea of the Titans being influenced by the Hetalia characters' personalities. Say, a really goofy Hetalia character might make a Titan act in a less menacing way just because it's so confused by the character's antics.
Lovi (Lovino Vargas from Hetalia) and Levi (from Attack on Titan) could be a likely pair. They both have that tough - exterior and are often seen as no - nonsense characters. Their interactions could be full of bickering and grudging respect. Another possible pair could be America (Alfred F. Jones from Hetalia) and Eren (from Attack on Titan). They are both quite headstrong and have a strong sense of justice, so they might team up to fight the Titans and try to bring about change in the world.
One possible fanfic could be about Mikasa's transformation into a Titan being a unique situation in the 'Attack on Titan' world. Maybe she has different abilities compared to other Titans. For example, she could retain more of her human consciousness and use her combat skills in Titan form. This would create an interesting dynamic as she tries to protect her friends while being a Titan, which is usually seen as an enemy.
No. The 'Attack on Titan' series has a set of official storylines, characters, and themes which are mainly centered around the fight against Titans, the mystery of the world, and the complex relationships among the characters. 'Attack on titan fart fanfic' is likely a fan - created and very non - traditional take that has no official standing in the series.
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.
The main difference is the 'lemon' aspect. In regular 'attack on titan' fanfic, it usually focuses on the adventure, the fight against the titans, and the general plot development. But 'attack on titan lemon fanfic' often includes some romantic or more intimate relationships between the characters, which might not be the main focus in the normal ones.
One possible fanfic plot could be that Eren has been planning this for a long time. He might gather intelligence about the Colossal Titan's weaknesses. Then, in a fierce battle, he manages to get close enough to deliver a fatal blow. This could be a very emotional moment for him as well, considering the history between them.
