Well, some fanfic writers like to create alternate endings for both Hunger Games and Divergent. They might rewrite the ending of the Hunger Games where Peeta doesn't get hijacked or in Divergent, Tris doesn't sacrifice herself. Additionally, there are fanfics that center around the relationships in a different way. For instance, exploring a deeper friendship between Gale and Finnick in the Hunger Games universe.
One popular idea is crossovers. For example, imagining characters from Hunger Games in the world of Divergent or vice versa. Another idea could be exploring different 'what if' scenarios. Like what if Katniss from Hunger Games was in a different faction in the Divergent world. Also, fanfics often focus on the backstories of minor characters from both series.
A cool fanfiction idea could be that the world of Divergent and the Hunger Games are actually two parts of a bigger experiment. The main characters from both universes start to discover this connection during a Hunger Games where some strange, Divergent - like abilities start to show up among the tributes, and they have to figure out what's really going on.
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.
Well, for Hunger Games, Gale is also quite popular in fanfiction. Some fans like to explore his relationship with Katniss further. In Divergent, Christina is a character that shows up a lot in fanfiction. She has a strong personality, and fans like to write about her adventures and relationships. In Hunger Games fanfiction, Finnick is another character that is popular. His charm and backstory make him an interesting subject for fan - created stories. In Divergent, Uriah is also somewhat popular in fanfiction, especially when it comes to stories about the Dauntless faction.
One interesting crossover could be characters from Divergent being thrown into The Hunger Games arena. For example, Tris could use her Dauntless skills to survive in the Games. Maybe she'd form an alliance with Katniss, and together they'd come up with new strategies that combine their different worlds' fighting and survival techniques.
Some cool concepts in Hunger Games fanfiction involve changing the rules of the games. What if there were no mentors? How would the tributes fare? In Divergent fanfiction, there's often a focus on characters who are Divergent in different ways than Tris. It could be someone who has a more extreme form of being Divergent and how they navigate the society. Another aspect in Hunger Games fanfic is the exploration of the Capitol's inner workings from a different perspective, not just the rebels' view. And in Divergent fanfic, imagining new initiation processes for the factions that test different qualities can be really engaging.
Four is also quite popular. His leadership and training abilities could potentially change the dynamics of the Hunger Games. He might be the kind of character who could organize an underground rebellion within the arena, much like he did in Divergent with the factionless.
One popular idea is a Hunger Games crossover with Harry Potter. Imagine tributes from the districts having magical abilities or facing challenges in the arena that are magically enhanced. Another is a crossover with The Maze Runner, where the tributes find themselves in a maze - like setting within the Hunger Games arena. A third could be a crossover with Divergent, with the factions being incorporated into the districts and the Hunger Games having different rules based on the faction - like qualities of the tributes.
You could also try Wattpad. While it has a wide variety of content, there are definitely some well - written Hunger Games and Divergent fanfics there. Just be aware that the quality can vary more compared to AO3. Some authors also have their own personal websites where they post their fanfics, but these can be harder to find. You might need to do some googling using the names of the series along with 'fanfic' and the author's name if you know it.
Another aspect could be the training methods. The training in 'Divergent' is very different from that in 'Hunger Games'. Fanfictions might explore how characters from both worlds would adapt to each other's training styles. For instance, Peeta could learn some of the self - defense techniques from the Dauntless in 'Divergent', which would give him an edge in the Hunger Games.
One idea could be creating an OC who is a master of disguise. They could use this skill to their advantage during the Games, hiding in plain sight or tricking other tributes. Another idea is an OC with a unique weapon, like a self - made slingshot that has special features. Maybe an OC who has a strong bond with an animal in the arena and tries to use that connection to survive.
