One common theme is loyalty. Levi is a very loyal character in the original 'Attack on Titan' series, and fanfics often explore his loyalty to his comrades, his cause, and his friends. For example, in many fanfics, he will go to great lengths to protect his fellow Survey Corps members.
Well, Levi Ackerman's back story is really something. He came from the Underground, which was like the worst place to be in that world. His mom passed away, leaving him alone in a dangerous place. But he managed to rise above it all. He became a skilled fighter. He has this no - nonsense attitude which was probably shaped by his rough upbringing. And his skills with a blade and in combat made him a valuable asset to the Survey Corps.
Fanfictions about Levi Ackerman x Reader often explore deep emotional connections. The relationship can be depicted in various settings, like within the Survey Corps. Writers might focus on how Levi's stoic nature interacts with the reader's character, creating a unique dynamic full of unspoken understandings and growth.
Fanfiction about Levi Ackerman and the reader can be really interesting. It often explores different aspects of their relationship. It could be set in the world of Attack on Titan, with the reader inserted into the story, perhaps as a new member of the Survey Corps. Their relationship might start off rocky due to Levi's tough exterior but gradually develop into a deep connection as they face the Titans together and overcome various challenges in the story.
I really like 'The Levi Chronicles'. It's a series of fanfictions that follow Levi through different events in the Attack on Titan universe. The author has a great understanding of Levi's character, his stoicism, and his unwavering loyalty. 'Under Levi's Command' is also a popular one. It focuses on Levi's leadership skills and how he manages to lead his team through difficult situations, all while maintaining his cool and collected demeanor.
There's also 'Levi in Middle - earth'. This fanfiction takes Levi to the world of J.R.R. Tolkien. His discipline and fighting prowess are a great fit for the battles against orcs and other dark forces in Middle - earth. The story does a good job of showing how Levi might adapt to this very different yet equally dangerous world.
