No, it's not appropriate. Fanfiction should focus on positive aspects like character development, friendship, or adventure. Sexual content in fanfic about these characters is disrespectful to the source material and its fans. It can also create a negative and unwholesome environment in the fan community.
The theme of trust is omnipresent. Their trust in each other's abilities is crucial. In many fanfictions, Levi trusts Erwin's strategic plans completely, even when they seem risky. Also, the idea of redemption can be a theme. For instance, if one of them has made a mistake, the other is there to help them redeem themselves, which is a very heart - warming aspect of their relationship in fanfiction.
Well, usually they might focus on the romantic or sexual relationship between Erwin and Levi. But since 'lemon' implies sexual content, it's not something that should be widely promoted. However, in non - lemon fics, characteristics could include exploring their different personalities, how they interact in the military setting, and their loyalty to each other.
Character - driven stories are also great alternatives. Develop the relationships between the Atlantis characters in a non - sexual way. Maybe write about the friendships, rivalries, and how they work together to build or protect their society. You could also explore their personal growth and how they adapt to the unique environment of Atlantis.
There are many alternatives. For example, one can write about the doctor's heroic medical saves, their relationships with patients in a platonic and caring way, or their adventures in the medical field like dealing with rare diseases or complex surgeries.
You can focus on adventure stories. For example, write about the characters in FFXV going on a new quest, exploring uncharted lands, and facing new monsters. This way, you can expand on the world - building of the game.
Rather than inappropriate sexual fanfic, you could write about her impact on society in the DC universe. How she has changed the way people view female heroes. Or write about her internal struggles, like how she balances her role as a princess and a superhero. You can also create crossovers where she meets characters from different universes and how they interact in a non - sexual context.
The fanfiction of Levi and Erwin's back story is filled with interesting details. Levi's past in the Underground gave him a unique perspective on life and survival. When he joined the Survey Corps, he brought that tenacity with him. Erwin, who was more of an idealist, was intrigued by Levi. Their back story could involve how they trained together. Erwin might have tried to instill his strategic thinking into Levi, while Levi taught Erwin some practical combat skills he learned from his tough life in the Underground. This exchange of knowledge and experiences is a key part of their relationship's development in fanfiction.
In many Attack on Titan fanfics about Levi and Erwin, their relationship is often complex and deep. Levi respects Erwin's leadership skills and strategic mind. Erwin, on the other hand, trusts Levi's combat abilities. Their relationship can be seen as a partnership that is crucial for the Survey Corps. They support each other in the face of the Titans and the many challenges within the walls.
One popular trope is the 'unspoken understanding' between them. They can communicate with just a look during crucial moments in battle or decision - making. Another is the 'protective Levi' trope, where Levi is always ready to defend Erwin from any threat, whether it's a Titan or a political enemy within the walls.
