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.
It's possible that new characters are introduced as well. Maybe there are some underground resistance leaders who see Rue as the symbol they need. These characters could have unique abilities or knowledge that help Rue in her fight against the Capitol. And of course, the antagonists from the Capitol would still be there, trying to stop Rue and the rebellion.
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.
Katniss and Peeta would likely still be main characters. Their story is so central to the original series that it would be natural for them to continue to play important roles in the fanfiction. Maybe it could focus on them as they age and deal with the memories of the past.
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.
Some characters might be shocked. For example, Katniss might find it strange to see alternate versions of her story. She could be angry if the fanfiction misrepresents her motives or actions. Peeta, on the other hand, might be more intrigued and try to understand the different perspectives presented in the fanfiction.
Katniss is still one of the most popular characters. Since she was the main character throughout the series, in fanfiction, she often continues to be a central figure. Writers might explore her new role as a leader or a mother in the post - Mockingjay world.
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 main theme is resistance. The characters are fighting against the oppressive Capitol. Another is sacrifice, as many characters give up their lives for the cause. And there's also the theme of power, showing how it can be misused by the Capitol and how the rebels strive to regain it.
The main themes include power struggle. The Capitol has held power over the districts for a long time, and the story shows the fight to shift that power. Then there's the theme of identity. Katniss struggles with her role as the Mockingjay and how that defines her. Also, friendship is a theme. Peeta and Katniss' relationship, as well as her friendships with others in the resistance, are important aspects.
One of the main themes is rebellion. The districts are rising up against the Capitol, showing the fight for freedom and justice. Another theme is sacrifice, as many characters put their lives on the line for the greater good. Also, the power of media is a theme, with the Mockingjay becoming a symbol through propaganda.
