Other tributes or survivors who are jealous or resentful could also be antagonists. They might not like the idea of Katniss and Finnick having a family when they have lost so much themselves. This could lead to conflict and attempts to harm them or the baby.
The Capitol could still be the main antagonists. They might see Katniss's pregnancy as a threat, either because they fear the child could grow up to be a symbol of resistance like Katniss or just because they want to maintain control over her. They could try to harm her or the baby in some way.
One possible plot is that in a world where the Hunger Games are over but the after - effects still linger, Finnick and Katniss find solace in each other. Their relationship develops, and soon Katniss realizes she's pregnant. The story could then revolve around how they deal with this new situation. Finnick, with his charm and skills, might try to secure a safe place for them and the baby. Katniss, on the other hand, could be conflicted between her old self - reliant ways and the need to protect her unborn child. There could also be a sub - plot about how the other characters from the series react to this unexpected turn of events.
Yes, there might be. The 'Hunger Games' fandom is quite large, and fans often create various fanfics. You can try searching on popular fanfic websites like Archive of Our Own (AO3). There are many writers who are inspired by the relationship between different characters, and a Finnick and Katniss pairing with a pregnancy storyline could potentially exist among the vast collection of fan - created works.
The Capitol would definitely be a main antagonist. They are always trying to control the tributes and the Hunger Games. With Katniss pregnant, they might see it as an opportunity to manipulate the situation for their own entertainment or to quell any potential uprisings. President Snow could be especially cruel in this scenario, using Katniss's pregnancy to threaten her and those she loves.
Another storyline could focus on the reactions of their families and friends to the pregnancy. Some might be overjoyed, while others could be worried about the added responsibility and the potential risks in their world. Katniss and Finnick would then have to navigate these different emotions and opinions.
One possible plot could be that after the war, they both realize they have a unique understanding of each other due to their experiences in the games. They get married and work together to rebuild their districts. Finnick's charm and Katniss' determination make them a powerful couple in this new world.
In fanfiction, it could be due to a misunderstanding. Maybe Katniss is trying to send a message to someone else but Finnick misinterprets it and kisses her. Or vice versa.
The Capitol officials would likely be the main antagonists. They might be the ones who create and enforce the rules of the diaper games, just like they did with the Hunger Games. They could be using these games to further control and humiliate the participants.
One great Katniss and Finnick fanfiction is 'The Unlikely Alliance'. It shows a unique take on their relationship, where they team up in the arena in a way that wasn't shown in the original books. The character development is really well - done.
In fanfiction, a Finnick and Katniss kiss can be a very interesting plot point. It might be a moment of unexpected connection. Maybe in the story's context, they are brought together by shared hardships in the Hunger Games universe. It could represent a break from their normal relationships or alliances.
