Another could be a love triangle between Hermione, Edward, and Jacob. Hermione's intelligence and strong will might make both of them attracted to her in different ways. She could be torn between Edward's brooding charm and Jacob's more down - to - earth nature.
Well, there could be a story where Hermione discovers a hidden diary of Lily Potter. As she reads it, she starts to adopt some of Lily's characteristics and wisdom. This could lead to her becoming a more empathetic and powerful witch, and also might help her in her relationships with Ron and Harry. In a different plot, Hermione could be magically transformed to look like Lily for a special mission, and during that time, she experiences the world from Lily's perspective, which changes her in many ways.
One interesting storyline could be Snape taking Hermione on as a special apprentice of sorts. He sees her potential in potions and dark arts defense far beyond her years and decides to privately tutor her. This could lead to a series of adventures where they explore ancient spells and potion-making techniques together.
A plot could be where Dolohov has a change of heart due to a mysterious encounter. He then approaches Hermione for help in escaping the clutches of the remaining Death Eaters. Hermione, being the brave and intelligent witch she is, decides to help him on the condition that he reveals all he knows about the Death Eater's plans. This leads to a series of tense interactions between them as they try to outwit the other Death Eaters.
Hermione would also try to use her magic to her advantage. For example, if she found herself in a dangerous situation with a vampire or a werewolf, she'd use spells for protection. And she'd probably try to educate the characters in the Twilight world about magic, which could be both confusing and exciting for them.
Another possibility is that Hermione, as a sorceress, has to face challenges within the Hogwarts community. For example, some students might be jealous of her powers and try to undermine her. But she overcomes this with her intelligence and the strength of her magic. In this type of fanfiction, we could see her form new alliances and learn new ways to use her magic to defend herself and those she cares about.
A great storyline might involve a fusion of the two worlds' mechanics. For example, the Velvet Room from Persona could have some connection to Joker's world. The Igor-like figure could offer Joker and his friends some new kind of power or knowledge that they use to combat a common foe. Or perhaps the Persona characters learn about Joker's Metaverse Navigator and try to replicate it in their world, which leads to all sorts of unforeseen consequences and adventures.
Another could be a time - travel scenario where Naruto goes back in time and meets Rikudou Sennin. They then team up to prevent a great evil from ever arising in the first place. This would allow for a lot of character development and exploration of the Naruto universe's history.
One of the most interesting storylines could be the interaction between the different species in Mass Effect and those from Stargate. For example, how would the Asari react to the Goa'uld? The Asari are a long - lived, biotic - using species in Mass Effect, while the Goa'uld are parasitic snake - like beings in Stargate. Another cool idea is the technology exchange. The Mass Effect universe has advanced biotic and cybernetic technology, and Stargate has its own unique wormhole - based travel and Ancient technology. A fanfiction could explore how these technologies might be combined or used against each other. Also, the cultural clashes would be fascinating. The different races in Mass Effect have their own moral and ethical codes, and the same goes for the races in Stargate. How would they deal with each other's values?
One interesting storyline could be Naruto using the Sharingan to enhance his combat skills in a new and unexpected way. For example, he might combine his Rasengan with Sharingan - powered genjutsu to create a more powerful and deceptive attack.
A crossover involving a shared enemy. Maybe a new alien race that is a threat to both universes emerges. The combined forces of Babylon 5 and Star Trek would have to pool their resources. The Starfleet officers could share their scientific knowledge to analyze the new threat, while the Babylon 5 personnel could offer their street - smart combat and negotiation skills developed from their own experiences in the often - tumultuous Babylon 5 station.
