If Rue won, it could lead to a very different outcome. Maybe it would inspire more rebellion or bring about a shift in the Capitol's control. It's an interesting 'what if' scenario that opens up a lot of possibilities for the story to unfold differently.
Rue could be the key to a rebellion in a fanfiction. After her death in the original story, her spirit could inspire the other districts. So in this fanfiction, she doesn't die. Instead, she unites the tributes from different districts against the Capitol. Her small and innocent appearance could be a disguise for her strong will and leadership skills.
In some fanfiction, Rue could have a connection with the Capitol that is not shown in the original. Maybe she has a distant relative who is trying to help her from the inside. This relative sends her small gifts or hints during the Games that give her an edge. It would add an interesting twist to her story and show a different side of the power dynamics in the Hunger Games universe.
One common theme is friendship. Fanfictions often focus on how Katniss and Rue form a deep friendship in the harsh environment of the Hunger Games. Another theme is sacrifice. Rue's selfless act in the original story can be further explored in fanfiction, like Katniss's reaction to it and how it shapes her later actions.
Obviously, Rue is one of the main characters as she is the Mockingjay in this fanfiction. There might also be characters from the original Hunger Games series who support Rue in her new role, like some of the tributes who survived and are now part of the rebellion.
In many Hunger Games fanfictions, Katniss and Rue's relationship is often one of mutual trust and sisterly affection. Katniss sees Rue as a symbol of innocence in the cruel Games. Rue, on the other hand, looks up to Katniss as a protector. Their bond is strengthened by their shared experiences in the arena.
One interesting idea could be Rue's different strategies as the Mockingjay. Maybe she uses her small and nimble stature in ways Katniss didn't. For example, she could be more stealthy in getting in and out of dangerous areas.
Peeta would be heartbroken. He had strong feelings for Katniss, so her death would be a huge blow. He might become more determined to win the Games in her memory, to carry out whatever she might have wanted in the Games.
It could be about an alternate universe where Cato and Clove, instead of meeting their fates in the original Hunger Games, manage to win. Maybe it shows how they deal with the aftermath of victory, like the political implications in the Capitol and their relationship with the other districts.
Rue represents the truth of the underdog in the Hunger Games novel. She comes from a small and relatively powerless district. Despite her size and lack of resources, she has a strong spirit and survival skills. Her presence in the Games shows that the Capitol's system doesn't always favor the strong or the well - equipped. Her death also reveals the truth that the Capitol doesn't value the lives of the tributes equally, but rather sees them as disposable pawns for their entertainment.
The main characters are Cato and Clove. Cato, with his imposing presence and fighting prowess, and Clove, with her sharp knives and sly mind. In this fanfiction, they are the stars. Their story of winning the Hunger Games is what the whole fanfiction is about. We can expect to see their growth, their struggles, and their interactions with other elements in the Hunger Games universe through their perspective as the victors.
