One idea could be a crossover with 'Survivor'. Contestants from both shows could be combined in a new race where they have to use survival skills along with the regular race tasks. For example, building a shelter as part of a checkpoint.
A crossover with 'Big Brother' would also be cool. The houseguests could join the race, and their social game skills from 'Big Brother' might play into how they form alliances during the race. Maybe they use their knowledge of reading people to negotiate better in the race challenges.
A crossover with the Avengers is also great. Picture Spider - Man having to prove himself to the more established heroes like Iron Man and Captain America. He could bring his unique street - level hero skills to a big - scale Avengers mission.
One idea could be a crossover with another Disney adventure movie like 'Pirates of the Caribbean'. The characters from 'Race to Witch Mountain' could end up on a pirate ship while trying to escape some new threat related to their original mission. Maybe the aliens from Witch Mountain have some sort of power that the pirates are after.
One idea could be a crossover with 'Adventure Time'. Gumball and Finn could go on a wild adventure together, facing challenges in a mixed - up world of both shows. Maybe they have to find a magical item that got lost between their universes.
A crossover with 'Steven Universe' would also be cool. Gumball and Steven could bond over their unique family situations. They could have to use the power of friendship, Gumball's wacky schemes, and Steven's gem powers to defeat a common enemy, like an evil gem who wants to turn Elmore into a gem colony.
In frieza race crossover fanfiction, a cool idea is the Frieza race having to deal with moral concepts from other races. Since the Frieza race is often portrayed as more ruthless, they might struggle with ideas like compassion and justice. Also, their unique biological features could be used in interesting ways. For instance, their ability to survive in harsh conditions could give them an edge in certain crossovers, like in a post - apocalyptic world crossover.
One interesting idea could be a crossover with "Moana". Elsa's ice powers and Moana's connection to the ocean could create a really cool dynamic. Maybe Elsa accidentally freezes part of Moana's ocean and they have to work together to fix it. Another could be with "Tangled". Rapunzel's long hair and her adventurous spirit combined with Elsa and Anna's journey in Frozen 2 would be exciting. Rapunzel could use her hair to help them climb mountains or cross chasms. A third idea is a crossover with "Beauty and the Beast". Belle's love for books and knowledge could help Elsa understand more about her powers and the history of magic in the Frozen world.
One idea could be a character who is tired of the rat race and decides to start a revolution within the corporate world. Another could be a group of friends in the rat race who discover a hidden treasure that changes their perspective on chasing wealth. Or perhaps a character who uses the chaos of the rat race to their advantage to achieve a personal dream that has nothing to do with money or status.
One idea could be exploring a new villain that is created from a scientific experiment gone wrong in Oscorp. This villain could have powers related to electricity and pose a new threat to Spider - Man.
A Rambo crossover fanfiction could involve him crossing over into the Star Wars universe. Rambo's guerilla warfare tactics could be interesting in a galaxy far, far away. Maybe he helps the Rebel Alliance in a ground - based battle against the Empire. Or a crossover with the Predator series. Rambo would be a worthy opponent for the Predator, and the fight between them in the jungle could be epic. Also, a Rambo and John Wick crossover would be intense, two highly skilled fighters on the same side or perhaps initially at odds.
One idea could be a crossover with a modern military setting. The Decepticons could be trying to steal advanced military technology. Another is a crossover with a post - apocalyptic world where they are competing with other factions for resources. A third could be a crossover with a magical realm, with the Decepticons trying to harness the magic for their own evil purposes.
