One plotline could be the discovery of the nameless hero's past. Maybe they were once a part of a secret experiment related to the Titans and this knowledge becomes crucial in the fight against them. Their past could hold the key to a new weapon or strategy.
Another possibility is that the nameless hero is an elder in the community. They might have lived through previous Titan attacks and have a wealth of knowledge and experience. Although they are not in the front lines of the fight, they could be guiding the younger generation, providing strategies and support that are crucial for survival. Their wisdom and advice could be what saves the day in many situations, making them an unsung hero.
A possible plotline might be that Eren and Annie are forced into a situation where they have to protect their unborn child from remaining threats in the post - Titan world. This could involve them teaming up with old friends and enemies alike. Or perhaps their pregnancy is the result of a scientific experiment gone wrong during the study of Titans, and they now have to deal with the consequences while also trying to ensure the safety of their baby.
One plotline could be Percy leading the Titans in a war against the gods. He might use his knowledge of the demigods' weaknesses to plan attacks. Another could be Percy trying to convert other demigods to his Titan side, causing division among them.
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.
One common crossover idea is a scenario where the Titans from Attack on Titan are considered as 'villains' in the My Hero Academia universe, and the heroes have to come up with strategies to defeat them. It could also be interesting to see how the Quirks in My Hero Academia would be perceived in the world of Attack on Titan. Maybe some characters would be seen as 'demons' because of their unique powers. And then there's the idea of a character from Attack on Titan, like Eren, somehow getting a Quirk in the My Hero Academia world and how that would change his character arc.
In a fanfiction scenario, the kidnapping could be a ruse by an old enemy who wants to break the team apart. They might brainwash the kidnapped member to turn against the others. The team would then not only have to rescue their friend physically but also find a way to break the brainwashing. This would involve a lot of emotional turmoil within the team as they deal with the betrayal, while also trying to stay focused on saving their friend.
One great Attack on Titan fanfiction is 'The Wings of Freedom Reimagined'. It delves deeper into the characters' backstories and gives a fresh perspective on their motives. Another is 'Beyond the Walls: A New Hope' which creates an interesting alternate universe where the Scouts discover a new, unexpected power source. And 'Eren's Redemption Arc' is also a popular one as it focuses on a different path for Eren's character development, showing his struggle with his inner demons in a more nuanced way.
A theme of hope could also be present. In Attack on Titan, the situation is often very bleak, but in the world of My Little Pony, hope and friendship are strong forces. So, a fanfiction could explore how the positive aspects of My Little Pony's world could bring new hope to the characters in Attack on Titan, or how the determination of the Attack on Titan characters could inspire the ponies in a time of crisis.
One good example could be a fanfiction where the Female Titan has an unexpected alliance with the main characters. In this story, she might reveal a hidden side of her nature that was not explored in the original series, like having a moral code that goes against her initial actions as an enemy. This can add a whole new layer of complexity to the character.
Well, one interesting concept could be exploring the origin of the Baby Titan. Maybe it has a unique backstory that ties into the overall lore of Attack on Titan. For example, it could be related to some secret experiment by the Marleyans or an unforeseen consequence of the Titans' existence.
