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.
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.
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.
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.
