A possible plot could involve the Persona users trying to understand the nature of Stands. They might initially mistake Stands for some new, unknown type of Persona. The JoJo characters, on the other hand, are confused by the different rules and mechanics of the Persona world. This misunderstanding could lead to both sides being cautious of each other at first, but then they gradually learn to work together as they realize they have a common goal, like saving both of their universes from a threat that spans across dimensions.
One idea could be to have the Stand users from JoJo interact with the Personas in a battle royale - style scenario. Maybe the JoJo characters are transported to the Persona universe and have to figure out how to use their Stands alongside the Personas to defeat a common enemy.
A great concept for a 'jojo persona crossover fanfiction' would be a tournament - style story. Characters from both universes are forced to participate in a battle royale. The Jojo characters would bring their Stands, and the Persona characters would have their Personas. The battles could be intense, with different strategies emerging. For instance, a Persona user might try to use psychological attacks against a Jojo character who is more used to physical combat with their Stand. And the story could also explore how the two groups of characters interact and form alliances outside of the battles.
A great plot could involve the transfer of Personas between the two groups. For example, a character from Persona 3 accidentally gets a Persona that belongs in the world of Persona 4 and vice versa. This causes chaos as they have to learn to control and understand these new entities while also dealing with the reactions of their respective teams.
One idea could be that the RWBY characters enter the Metaverse from Persona. They might have to face their Shadows, which could be related to their Grimm - fighting fears or personal insecurities. For example, Ruby could face a Shadow that represents her fear of not being able to protect everyone.
One idea could be the characters from Persona 4 and Persona 5 swapping their worlds. So the Phantom Thieves end up in Inaba and have to deal with the Midnight Channel mystery. And the Investigation Team finds themselves in Tokyo and gets involved in the Metaverse. It would be really cool to see how they interact with the different environments and characters.
Jonathan Joestar and Yu Narukami could be an interesting pairing. Jonathan's noble and chivalrous nature would contrast with Yu's more modern and relatable personality. They could learn from each other's sense of justice. Yu could teach Jonathan about the modern world and how to use some basic technology, while Jonathan could inspire Yu with his unwavering determination in the face of danger.
One idea could be to have the Jojo characters enter a popular video game world like Minecraft. They could use their stands to build amazing structures or fight off mobs in unique ways. For example, Star Platinum could be used to mine blocks at super - fast speed.
Well, in 'jojo crossover fanfic', a common concept is the fusion of stands. Imagine if Star Platinum and Gold Experience combined their powers in some way. This would lead to really creative battles and problem - solving within the fanfic's plot. Also, crossovers might include Jojo characters in different settings like modern day New York instead of their original locations, which is super cool.
One idea could be a crossover with another popular anime like Naruto. The JoJo characters could be transported to the Naruto world and have to deal with things like chakra and ninja techniques. They might use their stands in unique ways to combat the ninja threats. For example, Star Platinum could be used to quickly dodge and counter attacks from ninjas. Another plot could involve a crossover with the Fate series. The JoJo characters could be summoned as servants, and their stands could be seen as a form of their special abilities in this new context. This would create an interesting dynamic as they fight in the Holy Grail War.
A great plot for Persona 4 crossover fanfiction could be a crossover with the 'Sword Art Online' universe. The Persona 4 gang could be trapped in the virtual world of SAO and have to use their Personas to defeat the bosses and escape. Or, they could cross over with the 'My Hero Academia' world. Here, they could attend the hero school and learn new ways to use their powers, while also sharing their Persona knowledge with the MHA characters. Also, a crossover with 'Harry Potter' would be interesting. They could attend Hogwarts and discover that their Personas have unique interactions with magic.
A crossover with a post - apocalyptic world setting. The Persona 3 characters find themselves in a world destroyed by some great cataclysm. They have to use their Personas not only to fight the Shadows that lurk in this new world but also to survive against other desperate survivors and new, mutated threats. They might also have to find a way to restore the world using their Persona powers.
