Haymitch is another good choice. His wisdom and experience could guide Finnick and Katniss in their actions. He could also add some humor and a touch of realism to the fanfic as he is always cynical about the whole Hunger Games situation and the Capitol's control.
Johanna could also be included. She has her own rough past and strong personality. Her interactions with Finnick are already established in the original story, and her relationship with Katniss could be developed further. They could all form a sort of misfit group fighting against the Capitol's tyranny.
Honestly, it's hard to name just a few. However, some authors who seem to really get into the nuances of Finnick and Katniss's characters are often those who are also big fans of the original series. They study the books closely and are able to write fanfiction that feels true to the source material. You can start by looking at the works of authors who have been writing Hunger Games fanfiction for a long time as they likely have some great Finnick and Katniss stories as well.
A fanfic could explore a scenario where Finnick saves Katniss's life in a different way. Instead of in the arena, it could be in a Capitol raid. Finnick uses his knowledge of the Capitol's layout and his combat skills to keep Katniss safe. This could lead to a deeper connection between them as Katniss is indebted to Finnick for her life.
In many fanfictions, Katniss also plays an important role when it comes to Finnick and Peeta. Her relationship with both of them is so central to the original story that in fanfiction it can be explored in new and interesting ways. Whether it's her trying to understand their friendship or being caught in the middle of some sort of tension between them.
In some fanfiction, they interact as reluctant allies. They might start off distrusting each other due to the nature of the Games but gradually come to respect one another's abilities.
One great fanfiction could be about Finnick and Katniss teaming up in the arena in a way that wasn't shown in the original books. They use their unique skills to outwit the Capitol's new and devious traps.
One interesting fanfiction could be about Finnick and Katniss teaming up earlier in the Games and using their unique skills to outwit the Capitol's traps. For example, Finnick's charm and fishing skills combined with Katniss's archery and survival instincts make them a formidable duo.
Some of the best - written Katniss characters in fanfiction are the ones that show her vulnerability. In a particular fanfiction, Katniss breaks down after a particularly brutal event in the arena, and her relationship with Prim is what gives her the strength to get back up. As for Prim, the fanfictions that explore her innocence and how she gradually loses it in the face of the Capitol's tyranny are well - done. For example, a story where she witnesses the execution of a tribute from District 12 and how that changes her view of the world. The fanfictions that balance these aspects of their characters are the ones with the best - written Katniss and Prim.
Well, obviously Peeta and Katniss themselves are often well - written. In many fanfictions, Peeta's kind and selfless nature is further explored. For example, there are stories where he uses his baking skills to bring comfort to the other tributes in the arena. Katniss is also great in fanfiction, especially when her internal struggle with her feelings for Peeta and her role as the Mockingjay is delved into.
There are many great authors. One is 'MockingjayLover' who writes some really in - depth stories about Finnick. Another is 'PanemWriter' who often focuses on Finnick's relationships in their fanfics. And 'HungerGamesFan22' also has some good works.
Obviously, Annie and Finnick are the main characters. Annie is known for her skills and her unique personality. Finnick, on the other hand, is a well - known and highly skilled victor.
