You should also consider adding some unique elements to the story. Since it's a fanfiction, you can take some liberties. Maybe introduce a new character that affects their relationship. Or create a situation where Levi and Baby Eren have to work together to overcome a problem that is different from what we see in the original work. This will make your fanfiction stand out.
First, you need to understand the characters well. Levi is known for his strict and stoic nature, while Baby Eren has that potential for great power and a certain naivete. Then, create an interesting plot. It could be something like Eren being in danger and Levi having to save him in a creative way.
First, understand their characters well. Levi is stoic, disciplined, and highly skilled, while Eren is passionate and determined. You can start with a strong concept, like a new mission they go on together. Develop their relationship gradually, show their conflicts and how they resolve them. For example, if they disagree on a battle strategy, have them communicate and find a middle ground. Also, use vivid descriptions of the 'Attack on Titan' world to set the mood.
One popular type might be those that focus on Levi taking care of Baby Eren in a post - apocalyptic world. For example, stories where Levi has to protect Eren from other threats while also trying to understand his unique powers even at a young age.
The fanfiction might focus on the baby inheriting certain traits from both Levi and Eren. For example, the baby could have Levi's sharp observational skills and Eren's determination. The story could also show how their friends and comrades react to the new addition to their group. Some might be overjoyed, while others might be worried about the implications of having a baby in their dangerous world.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like Archive of Our Own. Just search for 'levi and eren kiss' and you'll find a variety of stories with different plotlines and writing styles.
In the manga, Levi and Baby Eren have a sort of mentor-protege dynamic. Levi looks out for Eren and tries to help him grow stronger while also keeping him safe.
It's hard to say exactly. The comic might focus on their interaction and the circumstances around the baby. Maybe there are elements of drama or adventure.
I have no idea. Such a storyline would be very unconventional in the context of Eren and Levi yaoi manga. It could be a creative departure or a completely fictional addition.
Fanfiction about Eren and Levi kissing can be quite interesting. It might explore a different side of their relationship. Some fanfictions in this regard could be about a moment of emotional intensity between them, where the kiss represents a deep connection that goes beyond their usual interactions in the original story.
Levi would probably be a very strict parent. He's used to discipline and order, so he'd likely enforce rules strictly. Eren, on the other hand, might be more lenient and encourage the baby to be adventurous and follow its heart.
I've never come across such a manga plot. It sounds quite unusual and not in line with the typical themes of these characters.
