One common theme is alternate universes. Writers like to explore what would happen if certain events in the original series had gone differently. For example, what if Lelouch had made different choices during his battles or negotiations.
Some dedicated anime forums might also be a good place to look for Code Geass Lelouch vi Britannia fanfics. For example, Anime-Planet has a community section where fans might share or recommend their favorite fan-written stories. Additionally, Reddit has subreddits related to Code Geass where you can ask for fanfic suggestions.
This fanfic idea presents a very interesting twist on the original Code Geass story. It would be exciting to see how the story unfolds with Kallen on the side of Britannia. Her skills and abilities could be used in different ways. For example, she could use her piloting skills to fight for Britannia against new threats, which would completely change the power dynamics in the Code Geass universe.
A good Code Geass Lelouch fanfiction is 'Lelouch in a Parallel Realm'. In this story, Lelouch is transported to a parallel world where the power dynamics and politics are different. He has to adapt and use his wits in new ways. 'Code Geass: Lelouch's Alliances' is also great. It shows Lelouch forming unexpected alliances and how those relationships shape his journey. And 'The True Ending of Lelouch' is a fanfiction that tries to give a more satisfying and conclusive end to Lelouch's story.
One great fanfic in this category is 'The Geass Exchange'. It explores an alternate scenario where Lelouch gives his Geass to a different character, Suzaku. This creates a whole new dynamic as Suzaku, with his own set of beliefs and moral code, has to grapple with the power of Geass. The story delves deep into how the Geass affects his relationships, not just with Lelouch, but also with other characters in the Code Geass universe like Euphemia. It's a really interesting take on the concept of Geass transfer and how it can change the course of events.
She could start to reform Britannia from within. Kallen is a strong - willed character. If she joins Britannia, she may try to influence the system to be more just. For example, she could work towards improving the treatment of the Elevens within Britannia's hierarchical society.
I'm not sure specifically as it's a fanfic. It could be about Lelouch from Code Geass in some sort of capsule - related situation. Maybe it's a unique take on his character, like he's trapped in a capsule and has to figure out a way to escape or use his Geass powers in a confined space. It could also involve some new plotlines with other characters coming to his aid or trying to stop him.
A good one is 'Code Geass: Supernatural Shadows'. Here, Lelouch encounters a group of supernatural beings who are also involved in the power struggles of the world. He has to form alliances and make difficult decisions. The fanfiction is exciting because it combines the strategic elements of Code Geass with the mystery and otherworldly aspects of the supernatural elements.
First, understand the character of Lelouch thoroughly. Know his motives, his strengths, and his weaknesses. For example, his desire for justice and his complex relationship with his sister. Then, create an interesting plot. It could be an alternate timeline, like what if Lelouch didn't get his Geass power? Also, make sure to keep the writing style engaging. Use vivid descriptions of the Code Geass world, like the mechs and the political intrigue.
The story mainly revolves around Lelouch Lamperouge. He obtains the power of Geass, which allows him to command others to do his bidding. In the context of love, there are complex relationships. Lelouch has deep emotional bonds with various characters. For example, his relationship with C.C. is full of mystery and mutual understanding on some levels. They share a connection through the Geass power and their common goals. Also, his feelings towards his sister Nunnally play a huge role in his actions and decisions throughout the story, as he is determined to create a better world for her.
