What are some interesting ideas for a Code Geass Prince OC Harem fanfiction?

A possible plot is the OC having a Geass that allows him to understand and communicate with all forms of life. This would make him very interesting to the different factions in Code Geass. The Britannian royalty might want to use him for political gain, while the resistance groups see him as a potential ally. Along the way, he forms a harem of characters from both sides who are drawn to his unique ability and kind heart.

One idea could be an OC who is a commoner but has a unique power that gets noticed by Lelouch. For example, the ability to manipulate sound waves which could be used for both stealth and attack. Another could be an OC from a foreign nation who has different moral and cultural values than the Britannians and Japanese, creating interesting conflicts. Or an OC who is a brilliant scientist working on a secret project that could change the balance of power in the Code Geass world.

Maybe a harem fanfic where Lelouch's Geass power has an unexpected side effect on the girls around him. Instead of just making them obey a single command, it creates a strong emotional bond that leads to the harem situation. The story could then explore how Lelouch deals with these new relationships while still trying to achieve his main goals in the Code Geass universe.

An OC with a unique Geass power, like the ability to manipulate time on a small scale. For example, they could slow down time for a few seconds to gain an advantage in combat or to escape dangerous situations. This would add a new dynamic to the battles and strategies in the Code Geass universe.

Another idea is that a character from the Naruto universe is transported to the Code Geass world and gains the Geass power. He then uses his ninja skills along with the Geass to build a harem. He might use his Geass to make female characters fall in love with him, but then has to deal with the moral implications of it, all while trying to survive in this new and dangerous world.

One idea could be an OC who has the power to manipulate time in a limited way. They could use this power to try and prevent certain tragedies in the Code Geass world, like the fall of certain regions. Another plot could involve an OC who is a master strategist from a different universe and has to adapt their skills to the complex politics of Code Geass. A third idea might be an OC who can communicate with machines, which could lead to some really unique interactions with the mechs in the series.

There's also 'A Prince's Redemption'. This fanfic delves deep into the moral struggles of the OC prince. It shows his journey from a somewhat lost and conflicted character to one who finds his true purpose. The writing style is engaging and it stays true to the overall tone of Code Geass.

For the prince, you can start by delving deeper into his existing traits. If he's usually seen as cold, show the moments when his cold exterior cracks, especially around the OC. For the OC, give her a clear backstory. If she's from a different culture, explore how that affects her interactions. For the harem members, define their individual motives. For instance, if one is a spy, show how she struggles between her mission and her growing feelings for the prince.

A good Code Geass OC Prince fanfiction should have a believable character. The prince should have his own unique personality traits, goals, and flaws. For example, if he's overly ambitious, there should be consequences for that. Also, it should fit well into the existing Code Geass universe. The power dynamics, the political intrigue, and the overall setting should be respected.

One interesting plot idea could be that the OC is a hidden rebel within the Britannian forces. They initially cross paths with Cornelia during a battle, and the OC's unique abilities catch Cornelia's attention. As the story progresses, they start to understand each other's motives better, despite being on opposite sides. Maybe the OC has a secret power related to mind - reading which helps them anticipate Cornelia's moves, and this leads to a series of tense encounters that gradually turn into a strange sort of respect and eventually something more.
