Obviously, Eren as a baby is the central character. But we can also expect to see his family members like his father, Grisha. His mother, Carla, would also be an important presence as she plays a significant role in Eren's early life.
One interesting idea could be exploring Eren's potential even as a baby in the context of the Attack on Titan world. Maybe showing how his early experiences, even as a baby, might shape his future determination against the Titans.
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.
Eren is a complex character. He has a strong will to fight for freedom and his actions are often driven by his desire to avenge his mother's death. Levi, on the other hand, is more stoic. He has a dark past which has shaped him into a no - nonsense, highly skilled soldier. In fanfiction, exploring how these two different personalities mesh or clash is a big part of it.
Mikasa is often paired with Dark Eren. Given their long - standing relationship in the original series, it's natural for fanfiction to explore how she reacts to his darker side. She might try to bring him back to the light or be conflicted about her feelings for him.
A theme that often comes up is destiny. Fans like to write about how even as a baby, Eren is already on a path towards his future as a Titan - shifter and a hero. It's about how his early days might be subtly guiding him towards that fate. For example, he might show signs of great strength or determination even as a tiny baby. And also, protection is a theme. His family and those around him are trying to protect him from the harsh reality of the world outside the walls, which is a big part of many baby Eren fanfictions.
In many fanfics where Eren dies in Attack on Titan, it can be a very emotional and thought - provoking experience. Some fanfics might focus on how his friends deal with his death. For example, Mikasa could be in deep mourning, and Armin might struggle with the loss while also trying to uphold Eren's ideals in a different way. It could also explore the political and social ramifications in the world of Attack on Titan after Eren's death, like how the different factions react to the end of the great threat he represented.
One great 'Attack on Titan Eren and Mikasa fanfic' is 'The Bonds Beyond the Walls'. It beautifully explores their relationship in a post - titan world. The author delves deep into Mikasa's loyalty and Eren's complex emotions.
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.
Historia in 'Attack on Titan' is significant as she represents the hidden secrets and power struggles within the walls. Her character development is a key part of the story's exploration of the society. Eren, being the main protagonist, is the one who initiates a lot of the action. His character embodies the themes of freedom and the will to fight against oppression. Together, they add different dimensions to the story. Historia's story arc is intertwined with Eren's, and their combined presence enriches the narrative.
It could be the kittens themselves. Maybe there's a lead kitten that has special abilities or a unique backstory related to the Attack on Titan world. For example, it could be a kitten that was experimented on by the same people who created the titans.
