The 'time - travel' theme can be a unique take on a Joker x reader fanfic. The reader could be from a different time period and their encounter with the Joker in his own time creates a whole new set of challenges and interactions. Or a 'parallel world' theme, where the reader and the Joker meet in a world different from the normal DC universe, with different rules and power dynamics.
Rather than seeking 'lemon' fanfics which are not suitable, you could try searching for platonic Joker x reader fanfics. These can be really interesting as they explore different aspects of their interaction, like how the reader might be a friend or an adversary to the Joker. You can use tags on fanfic websites to narrow down your search.
A fanfic idea could be set in a school or training academy where Gajeel is a tough instructor and the reader is a new student. The reader struggles to meet Gajeel's high standards at first, but through hard work and determination, they earn his respect. This could develop into a friendship and eventually something more romantic as they share their dreams and past experiences.
Friendship is a great theme. You could write about how the reader and grand highblood become friends despite their differences. Another theme could be adventure, where they embark on a journey together. Maybe they have to solve a mystery or face a common enemy.
One popular theme is friendship. Cortana could be a friend who helps the reader character through tough times, like solving a mystery or getting out of a dangerous situation in the Halo universe. Another theme could be mentorship, where Cortana imparts her knowledge to the reader.
One great non - lemon Shrek x reader fanfic is 'A Day in the Swamp with Shrek'. It focuses on the reader's adventure in Shrek's swamp, exploring the friendship aspect. Another is 'Shrek's Unusual Encounter' which has a really interesting plot about the reader helping Shrek with a problem in the fairy - tale world. And 'Journey with Shrek' where the reader and Shrek go on a journey to find a lost magical item.
One good theme could be Kushina guiding Naruto through his journey to become Hokage in a spiritual way. Since she is his mother, she could offer him advice and support from beyond the grave. Another theme could be exploring their family bond, like how Naruto discovers more about his Uzumaki heritage through Kushina's memories or something similar.
One common theme is friendship. The story could start with the male reader and Jack Frost becoming friends, perhaps the reader being the only one who can see Jack at first. They could go on adventures together in the wintry landscapes that Jack controls.
One great fanfic could be 'The Trio's Adventure'. It focuses on the friendship and unique interactions between the three characters without any romantic or inappropriate elements. It shows how they work together to solve problems in a historical or fictional setting.
One common theme is camaraderie. Since they are all part of the Survey Corps in the Attack on Titan world, fics often explore how they work together as a team. For instance, they might be on a dangerous expedition outside the walls, and the reader character helps Levi and Erwin come up with a strategy to defeat the Titans they encounter.
One popular 'x reader lemon fanfic' could be those in the Harry Potter fandom. Some writers create really engaging stories where the reader is inserted into the magical world and has a romantic and sometimes steamy encounter with a character like Draco Malfoy. However, it's important to note that such content might not be suitable for all audiences as it often contains adult - like themes.
