A crossover with One Piece might also work well. Joseph Joestar could find himself on the Grand Line, interacting with the Straw Hat Pirates. His hamon abilities could be a strange and new power for the pirates to encounter, and he could help them out in battles against the likes of the World Government or other powerful foes, while also learning about the Devil Fruits and Haki.
One idea could be a crossover with another popular anime like Naruto. For example, Jotaro could meet Naruto and they could have a battle of wills and powers. Naruto's positive attitude might clash with Jotaro's more stoic nature.
One idea could be the Persona characters getting sucked into the JJBA universe. For example, the Phantom Thieves could end up in Morioh and have to deal with Stand users while trying to find a way back home. They might team up with Josuke and his friends to fight a common enemy that's causing chaos in both their worlds in a strange way.
Well, you could focus on the character crossovers. Imagine Jotaro Kujo meeting Ichigo Kurosaki. Jotaro's cool and collected demeanor would contrast with Ichigo's more hot - headed nature. They could learn from each other's fighting styles. And then there's the possibility of Stand users having to adapt to the spiritual energy in the Bleach world and vice versa. This could lead to some really interesting power - up and training sequences for the characters involved.
Kakyoin and Luffy from One Piece would be an unexpected but fun pairing. Kakyoin's calm and strategic mind would be an interesting contrast to Luffy's carefree and impulsive nature. They could work together in a battle, with Kakyoin using his Hierophant Green to create distractions or attack from a distance while Luffy charges in head - first, using his Gum - Gum powers to take on enemies directly.
One interesting JJBA gamer fanfiction could be about a gamer who gets transported into the JJBA universe and has to use their gaming skills to survive the Stand battles. For example, they might be really good at strategic planning in games, and they apply that to outwit enemies with Stands.
Well, in jjba the gamer fanfiction, a cool idea is the inclusion of quests related to the JJBA universe. Characters could be sent on missions to retrieve ancient artifacts that are related to their stands or family history. It adds a whole new layer of adventure to the story.
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.
Well, first, the fanfic should respect the lore of both SCP and JJBA. If it starts messing up the basic rules of either franchise, it can be a turn - off. The pacing is also crucial. A good crossover will have a well - paced story that doesn't rush through the interactions and developments. And finally, the world - building. How the two universes are merged should be creative and believable, like how the locations from JJBA fit into the SCP facilities or vice versa.
One interesting JJBA x MLP fanfiction could be where the Stand abilities from JJBA are introduced into the world of MLP. For example, a pony might gain a Stand that gives it unique powers, like the ability to control time in a small area, similar to DIO's The World. This could lead to all sorts of adventures and challenges within the pony world as they figure out how to use these new powers and face off against villains who also might get their hands on Stand - like abilities.
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.
