A really cool plot could be that the Hunger Games are used as a punishment in the wizarding world. Wizards who break certain laws are sent to the Hunger Games as a form of extreme penance. And the characters from Harry Potter have to figure out how to use their magic in this new and deadly context. It could also explore how the non - magical people in the Hunger Games react to seeing magic for the first time.
One idea could be to combine the magical elements of Harry Potter with the survival aspect of Hunger Games. For example, wizards and witches from Hogwarts are forced to participate in a Hunger Games - like competition in a magical arena. They can use spells for survival and combat.
One interesting plot point is the combination of magic and survival skills. For example, in some fanfics, wizards have to use spells to hunt or defend themselves in the Hunger Games - like setting. Another is the clash of cultures from the two worlds. Hogwarts students with their magical upbringing facing the brutal and more practical world of the Hunger Games.
One interesting plot idea is the crossover of the unique skills from both worlds. For example, in some fanfictions, the Dauntless' fearless fighting skills are combined with the survival skills of the Hunger Games tributes. It creates really intense and exciting battle scenes.
Another plot could involve a group of tributes secretly planning to hijack the system that controls the Hunger Games starship arena. They form alliances not just to survive the games, but also to expose the tyranny of the Capitol - starship. They could use their knowledge of starship technology to outwit the game - makers.
Perhaps a fanfic where the fighter forms an unlikely alliance with a tribute from a much wealthier district. They combine their different strengths, like the fighter's combat skills and the other's knowledge of technology, to survive in the Hunger Games. This would explore how different districts can work together in unexpected ways.
One idea could be that the ponies from different pony tribes are forced into the Hunger Games arena. For example, the earth ponies might use their strength and connection to the land to find food and build shelters. The pegasi could use their flying abilities to gain a strategic advantage in the arena, like scouting from above. And the unicorns could use their magic for various things like defense or creating illusions to mislead opponents.
One idea could be changing the setting of the Hunger Games. Instead of a post - apocalyptic world, it could be set in a world where there's a strange magical curse that forces the games. Another could be focusing on a different type of tribute. For example, a group of scientists who are forced to compete and they use their knowledge in unexpected ways to survive.
One idea could be that Naruto and his friends are forced into the Hunger Games arena. Naruto might use his shadow clones to confuse opponents and search for resources. Another could be that the different ninja clans are pitted against each other in the Hunger Games, leading to some intense battles between rival clans.
One idea could be to focus on a new type of arena. For example, an arena that is constantly changing, like it shifts from a desert to a frozen tundra. Another could be to explore the backstories of the tributes more deeply. Maybe one tribute has a secret connection to the Capitol that they are trying to hide. A third idea is to have a group of tributes form an alliance not for survival in the games, but to send a message to the Capitol about the cruelty of the Hunger Games.
Well, you could write a fanfic where a tribute from a poor district discovers a hidden skill or talent during the training period before the Hunger Games. This could be something like an amazing musical ability that they use to gain sponsors. Or perhaps a story about two tributes from rival districts who fall in love during the pre - Hunger Games events. They then have to decide whether to fight each other in the arena or try to find a way to escape together.
