What are some popular oc crossover fanfiction ideas?

Some people like the idea of a Slenderman and Minecraft crossover in fanfiction. Picture Slenderman lurking in the blocky Minecraft landscapes, scaring the players. Another possible crossover is with the Gravity Falls universe. Dipper and Mabel could stumble upon Slenderman during one of their adventures in the strange town. And a crossover with the Resident Evil series would be intense. Slenderman in a world full of zombies and bio - horror threats would create a really complex and terrifying scenario for a fanfiction.

One popular theme is the meeting of different fictional universes' characters. For example, a character from a fantasy world like Middle - earth in 'The Lord of the Rings' meeting a character from a science - fiction world like the 'Star Wars' galaxy. Another theme could be the power struggles that occur when OCs (original characters) from different crossovers interact. They might have to compete for resources or influence in the new combined fictional setting.

Another interesting concept is to have an OC gamer from a racing game cross over into a post - apocalyptic action game. The OC would have to adapt their driving skills to navigate the dangerous terrain filled with zombies or other threats. They could use their modified cars from the racing game as a weapon or a means of escape in the new world.

One idea could be to have an original character (OC) who is a powerful mage enter the DxD universe. The OC could bring unique magic that the DxD characters have never seen before, causing both confusion and excitement. For example, the OC might have the ability to manipulate time on a small scale, which could be a game - changer in battles or interactions within the DxD world.

One idea could be an Arcosian OC crossing over into the Dragon Ball universe and teaming up with Goku to fight a new powerful enemy. Another could be an Arcosian OC in a crossover with a more modern anime like My Hero Academia, where they use their unique powers in a hero - villain setting. Maybe an Arcosian OC in a crossover with Naruto, sharing their combat techniques with the ninja.

One idea could be to cross your original character (OC) with the world of RWBY and have them be a transfer student at Beacon Academy. They could bring unique skills or powers from their own world, like a magic system that RWBY doesn't have. Another idea is to have the OC be from a different time period and get thrown into the RWBY universe, causing all sorts of chaos and new storylines. For example, an OC from a steampunk world with advanced machinery could introduce new tech to the RWBY characters.

You could do a crossover with a post - apocalyptic world. Naruto characters find themselves in a world full of ruins and new threats. The oc could be a survivor from that world who teaches the Naruto characters new survival skills, and in return, the Naruto characters teach the oc about chakra and ninjutsu.

A cool crossover would be with the One Piece universe. Rin could be on a pirate ship, using his powers during sea battles and exploring the Grand Line. Another idea is a crossover with the My Hero Academia world. He could attend U.A. High and learn about different quirks while also showing off his own unique abilities. A crossover with the Inuyasha world would also be great. He and Inuyasha could team up to fight demons together.

Another popular crossover is with the Pokémon world. Samus exploring the Pokémon regions, perhaps using her skills to help or hinder trainers. She could encounter powerful Pokémon and have to use her own abilities to get out of tricky situations. It's an interesting contrast between her high - tech world and the more natural, creature - based world of Pokémon.

One popular idea is a crossover between 'Naruto' and 'One Piece'. Imagine Naruto characters on a pirate ship or Luffy trying to learn ninjutsu. Another is 'Sailor Moon' and 'Cardcaptor Sakura' crossover, where the magical girls team up to fight a common enemy. And a 'Dragon Ball' and 'Fullmetal Alchemist' crossover could be interesting, with the powerful Dragon Ball characters in the world of alchemy.
