It could also create chaos. The relationships between characters would be severely affected. Kallen, if aware of certain fanfiction versions of her story, might react strongly. She could either be inspired to fight harder for her beliefs or become confused about her role and identity in the grand scheme of things. Fanfiction often takes creative liberties, and these new understandings could completely rewrite the dynamics among the characters.
Lelouch's development would be interesting. In fanfiction, his character can be portrayed in many different ways. If he learned this, he might adapt some of the more positive traits from those versions. Maybe he'd become more empathetic earlier in his quest for justice, which could change how he interacts with his allies like C.C. and his sister Nunnally.
In Code Geass fanfiction, characters might watch a variety of things. They could watch the political machinations within the Britannian Empire. For example, Lelouch might watch the movements of the nobility to plan his next strategic move in his fight against the empire. They may also watch the battles between the Black Knights and the Britannian forces, analyzing the strengths and weaknesses of both sides. Additionally, characters could be watching the reactions of the general public to the events unfolding, as public sentiment is crucial in the power struggle depicted in the Code Geass universe.
Lelouch is surely one of the main characters. His complex personality and his grand plans in the Code Geass world would play a role in any love story. C.C. is also likely to be a main character, as her relationship with Lelouch has elements of mystery and potential for a deeper emotional connection.
Characters can be developed by giving the gamer character new goals. For example, if the gamer is in the Code Geass world, they might start with just wanting to survive but then develop a goal of overthrowing the Britannian regime for the good of the people. As for existing characters like Lelouch, they can be developed further by having interactions with the gamer. Lelouch could learn new strategies from the gamer's game - like thinking.
C.C. is also popular. Her mysterious nature and connection to Geass can be further explored in the context of the gamer fanfiction. Maybe she has some hidden knowledge about the 'gamer' system that she reveals to the protagonist at crucial moments.
In Naruto fanfiction, Sasuke is often a very popular character. His complex backstory and his journey for power make him an interesting subject for fan - created stories. In Code Geass, Lelouch is extremely popular. His intelligence and his use of the Geass power to try and change the world are very appealing to fans.
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.
In most cases, yes. Fanfiction is a form of creative work by fans, and as long as it doesn't violate any copyright laws in a major way (like using the original work for commercial gain without permission), it's generally okay to view. However, the legality can get a bit murky in some situations, for example, if the fanfiction contains elements that are too close to the original's plot in a way that could be seen as copyright infringement.
