There's a fanfic titled 'Geass Transference'. It's about Lelouch giving his Geass to an OC (Original Character). This allows for a lot of creativity as the author can shape the OC's backstory and motives. The story shows how the OC tries to understand and control the Geass power. It's different from the usual Code Geass stories as it's not centered around the main characters we know so well. It gives a fresh perspective on the Geass concept and how it can be used in various situations.
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.
I've read a fanfic called 'Unexpected Geass Recipient'. In this story, Lelouch gives his Geass to Kallen. Kallen's strong personality and her loyalty to the resistance add a new layer to how the Geass is used. She starts to use it in ways that Lelouch hadn't anticipated, which makes for an exciting read. The fanfic also focuses on how Kallen's relationships with her comrades change due to the power she now holds. It's a good exploration of character development within the context of the Geass.
