One idea could be that the OC has a special skill, like being able to communicate with animals in the arena. This could create an interesting dynamic with Cato as they navigate the Hunger Games. Another could be that the OC has a past connection to Cato that neither of them remember until a crucial moment in the arena. It could add an emotional layer to their relationship.
Well, a great plot for their fanfiction could be centered around a secret alliance within the Games that they form with other tributes. They could be using this alliance not just for survival but also to take on the Capitol in their own way. For example, they might try to expose some of the Capitol's secrets through the arena's cameras. Another idea is a story about Cato and Clove's relationship before they entered the Hunger Games. Perhaps there was a love triangle with another tribute from District 2, which added tension to their bond. And also, a plot could revolve around Cato and Clove finding a way to change the rules of the Games from within the arena.
One idea could be a pre - Hunger Games story where Cato and Clove train together and form a deeper bond than just allies. Maybe they share their fears and dreams away from the prying eyes of the other tributes. Another could be a fanfiction where Cato and Clove somehow survive the Hunger Games and have to deal with the aftermath in the Capitol, facing the political intrigue there. A third idea is a story from Clove's perspective during the Games, how she really feels about Cato and their chances of winning together.
One idea could be exploring their backstories before the Games. Maybe they trained together and had a special bond even then. Another could be a what - if scenario where they both survived the Games and had to deal with the aftermath in the Capitol.
A possible plot could involve Glimmer getting injured and Cato having to decide whether to save her or leave her behind for his own survival. This would create a great internal conflict for him. Or perhaps there could be a fanfiction where they both survive the Games through some sort of miraculous turn of events and then have to face the Capitol's wrath for breaking the rules.
One plot idea could be a pre - Hunger Games story where Cato and Glimmer form an alliance based on mutual ambition. They train together secretly, sharing their fears and desires for victory. Another could be a what - if scenario where they survive the initial bloodbath and have to rely on each other more than they expected in the arena, leading to a deeper emotional connection. Maybe a post - Games story where Glimmer's family tries to seek revenge on Cato for her death, but discovers there was more to their relationship than meets the eye.
One idea could be that Cato and Clove are in a high school version of the Hunger Games training program. They could be rivals at first, constantly trying to outdo each other in combat skills training. Then, as they face tougher challenges together, they start to develop a grudging respect for one another.
One way to develop Cato is to put him in situations where his beliefs are challenged. In the fanfiction, the OC could have different values than Cato. As they interact, Cato has to decide whether to stick to his old ways or adapt. For instance, if the OC believes in mercy towards other tributes and Cato doesn't, this conflict could lead to character growth for Cato as he re - evaluates his own views.
Maybe the OC is pregnant and it's a result of a forced situation in the Capitol. This could add a whole new layer of motivation for her in the Hunger Games. She could be fighting not just for her own survival, but also for the future of her unborn child. And she might form alliances with other tributes who are sympathetic to her situation.
One interesting Cato fanfiction could be about his backstory before the Games. It might explore his training and the pressures that led him to become such a fierce competitor. For example, it could show how his district's harsh conditions and the expectations placed on him molded his aggressive nature.
Some fanfictions might focus on Cato's thoughts and emotions during the Games. We could see his internal struggle between his survival instinct and his sense of honor. There could also be a fanfiction where he teams up with an unexpected ally, which changes the whole dynamic of the Games for him.
