One common theme is power. Margaery was very much involved in the power struggles in King's Landing. Fanfictions often explore how she might gain more power, or use it differently. Another theme is love and relationships. Her marriages and the politics behind them are frequently explored.
Yes, there are many. You can find some on fanfiction websites like Archive of Our Own. There, you'll discover various interpretations of Margaery's character, her relationships, and her role in the complex world of 'Game of Thrones'. Some fanfictions might focus on her political maneuvers, while others could explore her personal relationships in more depth.
Power is a very common theme. Since Margaery is a very politically - minded character in the show, fanfictions often explore how she gains and wields power. Another theme is her relationships, be it with her family, her husbands, or other nobles.
Joffrey is often characterized as even more cruel and unhinged in fanfiction. His violent outbursts and lack of mercy are sometimes exaggerated. Margaery is usually shown as a very intelligent and manipulative woman. She uses her beauty and charm to her advantage.
Margaery can also be a symbol of hope or change in fanfictions with a male OC. If the male OC is disillusioned with the current state of Westeros, Margaery could represent a new way forward. Her charm and intelligence can inspire the male OC to support her in her plans to reform the kingdom. Their relationship then becomes a driving force for the plot, as they strive to make Westeros a better place while also dealing with their own personal feelings for each other.
There are also those who write crossovers involving Margaery Tyrell. For instance, an author who combines the 'Game of Thrones' world with another fantasy realm and still manages to keep Margaery's character true to her original self can be considered a great author of her fanfiction. However, it's really up to individual readers to decide who the best is based on their own preferences.
In fanfiction, Joffrey and Margaery's relationship is often complex. Joffrey was a cruel and unpredictable character. Margaery, on the other hand, was more calculating. In some fanfictions, Margaery might be seen as trying to manipulate Joffrey for her own gain, like gaining more power in King's Landing. Their relationship could be full of political intrigue and power plays as they both come from powerful families with their own agendas.
There are fanfictions that focus on Margaery's relationship with other characters like Sansa. For example, they could form an alliance and work together to change the fate of the Seven Kingdoms. This would show a different side of Margaery, as she is usually seen in relation to the Lannisters or her own family, the Tyrells.
Well, I really liked the fanfiction 'Margaery's Garden'. In this story, Margaery uses her love for gardening as a metaphor for her growth in power. It gives a different perspective on her character. Then there's 'Margaery and the Smallfolk' which focuses on her interactions with the common people. This shows her as not just a power - hungry noble but also someone who cares about the general populace. And 'Margaery's Trials' is a good one too, it shows how she overcomes various difficulties in King's Landing.
