Lelouch is always a memorable character. In the fanfic, his complex personality and strategic mind might be further explored. He could have new challenges and dilemmas that make him even more engaging. Another would be C.C. Her mysterious nature and her connection to Geass are always interesting. In the fanfic, she might have a different role, like being more of a mentor to other characters.
One of the most memorable characters could be a new character introduced in the fanfic. For example, a character with a unique Geass power that no one has seen before. This character could disrupt the existing power balance and create new storylines. And of course, the Emperor of Britannia. In the fanfic, his tyrannical rule could be depicted in a more detailed or different light, making him a character that readers can't forget.
In Code Geass Lost Stories, the main characters are many. Lelouch Lamperouge is a central figure. His Geass power and his quest for revenge against Britannia drive much of the story. C.C., the immortal witch, is crucial as she has a deep connection with Lelouch. Suzaku Kururugi, with his strong sense of justice and his skills as a Knightmare Frame pilot, plays a significant role. There are also other characters like Kallen Stadtfeld, a rebel who fights against Britannia and has her own story arc within the game's narrative.
One interesting concept could be alternate endings for the characters. Maybe in the fanfic, Lelouch has a different fate than in the original series, like instead of his sacrificial end, he manages to find a way to rule Britannia without all the bloodshed. Another concept could be new Geass powers. For example, a character might develop a Geass that can control technology rather than just people.
The gameplay in Code Geass Lost Stories typically involves strategic battles. You control characters from the Code Geass universe and use their unique abilities. There are different mission types, like story - based missions that follow the plot of the series, and side missions for extra rewards.
One great 'Code Geass' fanfic focusing on characters could be one that delves into the backstory of Lelouch. For example, it might explore his life before the events of the series, his relationship with his sister Nunnally in more detail. Maybe it shows how he developed his strategic mind even at a young age. This kind of fanfic can add depth to the character and make the readers understand his motives better in the original series.
Fanfics often take on different genres as well. Some Code Geass Code Fanfic are action - packed adventures that take the characters on new quests outside of the original storyline. Others could be more of a mystery, where the characters have to solve a complex problem that was not part of the original plot. And then there are the ones that are more character - driven, focusing on the emotional growth and development of the characters.
The relationship between Lelouch and Suzaku is also a memorable plotline. They start as friends but end up on opposite sides due to different beliefs and goals. Suzaku believes in working within the system to change Britannia, while Lelouch takes a more radical approach. Their clashes and moments of understanding throughout the series add a lot of depth to the story.
Lelouch is often still a central figure. His complex character and his journey of trying to change the world make him a favorite to explore further in fanfics. Writers can take his story in new directions, such as showing his life after achieving his goals in different scenarios.
One interesting 'Code Geass Fanfic' could be about Lelouch having to face an unexpected new enemy that is immune to his Geass. It would add a whole new layer of challenge to his plans.
In 'Code Geass Sequel Fanfic', Lelouch remains a top pick among fans. His intelligence and ability to manipulate situations are always interesting to write about. C.C. is popular not only because of her connection to Lelouch but also because of her immortality and the secrets she holds. Another character that gets a lot of attention is Schneizel. His strategic mind and his role in the political landscape of the Code Geass world make him a character that can be explored further in sequel fanfics. And of course, fan - created characters that interact with the original cast in unique ways can also become very popular.
I'm not sure which characters are the main ones in this particular fanfic. It could be Lelouch, as he is a central character in the original Code Geass series. Maybe it also includes C.C., who has a significant role in the story. But without reading it, it's hard to say for sure.
