It could be really interesting. Imagine the characters from Glee suddenly thrust into the brutal world of the Hunger Games. The singers and performers from Glee would have to use their wits and any hidden survival skills. For example, Rachel Berry might try to use her show - stopping voice to gain sponsors, much like the tributes in the Hunger Games do to get supplies. And the different cliques in Glee could form alliances similar to the district alliances in the Hunger Games.
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.
The combination of two very different universes is exciting. Glee is about high school drama and music, while Hunger Games is a dystopian survival story. When combined in fanfiction, it creates unique scenarios. For example, seeing Glee characters in the Hunger Games arena or Hunger Games characters joining the Glee club.
Another option is to check out Reddit. There are subreddits dedicated to both Glee and Hunger Games. You can post a request for 'glee hunger games fanfiction' in those subreddits. Chances are, some fellow fans will come forward with great recommendations or even their own written works that they are proud to share.
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.
It could be really exciting. Imagine Harry Potter characters in the arena of the Hunger Games. Maybe Harry would use his magic skills to survive, like creating protective spells against the various threats in the arena. Hermione could use her intelligence to strategize, similar to how tributes in the Hunger Games plan their moves.
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.
First, you need to decide which two universes you want to cross over. For example, if it's Hunger Games and Game of Thrones, figure out how the political intrigue of Game of Thrones can be incorporated into the Hunger Games world. Then, think about your characters. Will they be a mix of existing characters from both universes or new ones? Next, create a basic plot. Maybe the tributes in the Hunger Games are being influenced by the power struggles in the other universe. Finally, start writing, don't worry too much about making it perfect at first.
It could be really exciting. Maybe Percy and his demigod friends get thrown into the Hunger Games arena. Percy could use his water powers to his advantage, like creating water barriers or using water currents to move around quickly. The demigods' unique abilities would make for some very interesting battles against the regular tributes from the Hunger Games.
A possible plot is that the Capitol in the Hunger Games discovers the existence of vampires from Twilight. They see them as a new form of entertainment and try to capture them to put in the arena. However, the vampires are not so easily controlled. Katniss and her allies could team up with the vampires against the Capitol. This would bring together the themes of rebellion from Hunger Games and the supernatural elements of Twilight.
