One common theme is redemption. Since Lelouch has done many morally ambiguous things in the original series, some fanfics focus on him trying to make up for his past actions. Another theme is love and relationships, such as his relationship with C.C. or his sister Nunnally.
Common themes include the exploration of his Geass power further. Maybe it has evolved or has new limitations now that he's alive. Family also plays a role, not just his relationship with Nunnally but also his family's legacy. Additionally, some fanfics focus on the geopolitical situation in the Code Geass world. How Lelouch's survival affects the balance of power between Britannia and the other nations is a recurring idea. It's all about taking the rich world of Code Geass and expanding on it with Lelouch still in the picture.
Well, power and its consequences are often explored. Lelouch was all about power in the anime, and in fanfics where he's alive, it's common to see how he continues to deal with the power he wields. Also, the theme of identity comes up a lot. With his Zero identity and his real self, fanfics may explore how he reconciles these two aspects of himself now that he's alive and still in the public eye. And of course, there are fanfics that center around the idea of a new world order that he tries to create or influence in a different way than in the original series.
Well, often the theme of isolation is present. Lelouch was a very lonely character in many ways. In a suicide fanfic, this isolation could be exacerbated. He might feel that no one truly understands him or his motives. It could also explore the theme of power and its consequences. Lelouch had great power with his Geass, and his suicide could be a way of escaping the burden of that power. Maybe he realizes that the power has corrupted him in some ways or led to too much destruction, and death is his way out. And then there's the theme of legacy. His suicide could be seen as a way to leave a certain kind of legacy, whether it's a martyr - like one or a cautionary tale about the pursuit of power.
One more theme that pops up a lot is the exploration of 'what - if' scenarios. Fanfic writers like to play with the idea of what would have happened if certain events in the series had been different regarding Lelouch and Shirley. For instance, what if Shirley had found out about Lelouch's true identity earlier? This leads to different relationship dynamics and storylines in the fanfics, which is really interesting to read about.
One common theme is the exploration of gender roles. Since Lelouch is female in these fanfics, it often challenges the traditional male - dominated power dynamics in the original Code Geass world. For instance, a female Lelouch might have to use different strategies to gain power and respect.
Yes, there are quite a few. You can start by looking on fanfiction platforms like FanFiction.net or Archive of Our Own. Some fanfics might focus on Lelouch's new life after the events of the series, exploring his relationships and new adventures.
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.
One common theme is the exploration of their complex relationship. Given their unique personalities and the circumstances in the Code Geass world, fanfics often focus on how they understand and support each other. Another theme is the idea of power and sacrifice. Since both Lelouch and CC are tied to power in different ways, many fanfics will play with the concept of what they are willing to sacrifice for each other or for their goals.
Love and loyalty are common themes. The fanfictions often explore the deep bond between CC and Lelouch.
Power dynamics is also a theme. Euphemia was a princess and Lelouch was a revolutionary in a way. Fanfictions may explore how their relationship affects the power balance in the world of Code Geass. It could be about them using their combined influence for good or the struggles they face because of their different positions of power. And also, the theme of sacrifice might be present, as they both had to make sacrifices in the original story, and fanfictions can expand on that concept in relation to their relationship.
The themes of sacrifice and redemption are quite common. Rolo, in particular, has actions that could be seen as in need of redemption, and Lelouch's own goals often require sacrifice. Fanfics may focus on how Rolo tries to redeem himself in Lelouch's eyes or how Lelouch sacrifices for Rolo. Additionally, the theme of power and control is present. Lelouch has the Geass power, and how he uses it in relation to Rolo and their relationship can be a central theme in fanfics.
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.
