Yes, there might be. The Naruto and Attack on Titan fandoms are both huge, and fans often like to cross over their favorite characters in fanfiction. So it's quite possible to find Eren - from Attack on Titan - in Naruto fanfiction. However, it may not be as common as fanfictions within each respective universe.
One common theme could be friendship. Even in the context of being animal hybrids, the relationship between Eren and Levi might be centered around mutual understanding and support. Another theme could be self - discovery as Eren goes through the experience of being an mpreg in this unique setting.
Some popular ones might include those that explore different relationships Eren could have in an alternate universe. For example, fanfics where Eren has a deep friendship with female characters that turns into something more.
One common theme is identity. Since it's a female version of Eren, exploring how she fits into the existing world and how her gender changes or doesn't change the core of the Eren character is often explored. For example, in some fanfics, she still has the same drive for freedom but faces different obstacles as a female.
Yes, there might be some out there. Some fanfic writers focus on creating non - adult, more family - friendly or platonic interpretations of such concepts. You can start by looking on fanfic platforms like Archive of Our Own and filter for the appropriate tags to avoid any adult - themed works.
The relationship in 'Attack on Titan Eren x Reader Lemon Fanfiction' is a creative take on the characters. Since it's fanfiction, the writer has the freedom to shape the relationship in various ways. Eren's character traits, like his determination and strong will, can be intertwined with the reader's character (even if it's a self - insert or a more general 'reader' character). The 'lemon' tag often indicates a more adult - themed relationship exploration, which could include romantic encounters, but it doesn't have to be just about that. It could also be about the emotional closeness that develops between them in the face of the challenges in the 'Attack on Titan' world. For example, they might find solace in each other during the chaos of the titan attacks, and this shared experience could deepen their bond in ways that are unique to the fanfiction's narrative.
One common theme is the adjustment to married life. Since they have different personalities, like Levi being more reserved and Eren more impulsive, they have to learn to understand and compromise with each other. Another theme is the protection of their relationship from external threats, whether it's other people's opinions or dangerous situations in the story's world.
