Sam Winchester would be really interesting. His research skills could help figure out the strange rules and secrets of the Hunger Games world. Peeta Mellark could also be a great addition. He's good at strategy and forming alliances, and he could form an alliance with Sam. And then there's Crowley. The King of Hell could be a wild card in the Games, either helping or hindering the tributes depending on his own motives.
I think Johanna Mason would be an exciting character to include. Her no - nonsense attitude and survival skills could match well with the Winchester brothers. Gabriel from Supernatural would also be cool. He could use his trickster powers to mess with the Hunger Games system. And Primrose Everdeen. She could be a symbol of hope in this dark crossover world, and the Winchester brothers would be determined to protect her.
Definitely Katniss. Imagine her in an arena filled with Halloween - themed traps and challenges. She would be the one to cut through the spooky nonsense and focus on survival. Gale could also be a great addition. His hunting skills would be put to the test in a different way, like hunting down muttations that are disguised as Halloween creatures. Then there's Cinna. He could design some amazing Halloween - inspired outfits for Katniss that not only look great but also have some hidden functions. For example, a dress that can turn invisible in the dark like a ghost. Finnick could also be interesting, with his charm and his ability to adapt to the strange new Halloween - themed Hunger Games environment.
A demigod of Hermes would be really interesting. They would be super fast and sneaky, able to steal supplies from other tributes without being noticed easily. They could also be great at making alliances and then double - crossing when it suits them, just like the trickster nature of Hermes.
Anthony Bridgerton would be a great character to include. His strong sense of family and his often stubborn nature could lead to some interesting clashes in a crossover. Say, in a crossover with a fairytale world like Cinderella. He might initially be against the idea of the Bridgerton family getting involved with the magic and 'foolishness' of the fairytale world, but then gradually change his mind.
I think Hermione would be the most interesting. She's so intelligent and resourceful in the Harry Potter series. In the Hunger Games, she would be able to analyze the situation quickly, figure out the best hiding places, and find ways to outwit the other tributes. Her knowledge of magic would also give her an edge, like using spells to find food or water.
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.
Twilight Sparkle would be really interesting. Her powerful magic skills would make her a strong contender. She could use her intelligence and knowledge of spells to outwit her opponents. Also, Rainbow Dash with her speed and flying skills could be a force to be reckoned with. She'd be zipping around the arena, trying to find the best vantage points.
Percy Jackson himself would be a likely survivor. His powers over water, his combat skills, and his ability to think on his feet would give him an edge. Annabeth Chase would also be a strong contender. Her intelligence and strategic thinking would help her navigate the challenges. Also, Katniss Everdeen from The Hunger Games. She is a skilled archer and survivor, so she could hold her own against the demigods and the other threats in the crossover arena.
Artie could be a surprising survivor. Despite his wheelchair, he's very intelligent. In a Hunger Games crossover, he could use his brains to outsmart the other tributes. He might be able to set up traps or figure out the best hiding places. Also, the other characters might underestimate him because of his disability, which could work to his advantage.
I think Rock Lee could survive. His physical strength and speed, along with his determination, would serve him well. Also, Shikamaru. Despite not being as physically strong as some others, his high intelligence would enable him to outwit his opponents and avoid dangerous situations in the Hunger Games arena.
Often, the baby tributes with the most unique abilities are the most interesting. For instance, a baby who can communicate with animals in this fanfiction world stands out. Their ability could give them an edge in the 'games' and also make for some really cool storylines.
