What are some interesting plot ideas for shadowhunters and twilight crossover fanfiction?

A fanfiction could explore the idea of a character from Twilight becoming a Shadowhunter. For example, Bella could discover she has Shadowhunter blood and has to leave the vampire - werewolf drama behind to learn a whole new set of skills and rules in the Shadowhunter world. It would be interesting to see how she adapts and how her relationships with Edward and Jacob change as a result.

One plot idea could be that the Shadowhunters need to find a way to defeat a powerful demon that can only be weakened by a special type of music. So they seek out the Glee club. The Glee club members are hesitant at first but then realize the importance of their role. Another idea is that a spell gone wrong in the Shadowhunters' world sends some of their key characters to the Glee club's world. There, they have to adapt to high school life while also trying to find a way back. And the Glee club helps them blend in and in return, they learn about the Shadow World.

Another option is a crossover with the Harry Potter universe. The Shadowhunters could end up at Hogwarts, perhaps because there is some sort of dark magic that is spilling over into the mundane world that they need to stop. They would be amazed by the magic in the wizarding world, and there could be some funny moments as they try to understand how things work there, while also trying to keep their own identities and purposes a secret from the wizards.

Another plot could involve an OC who comes from a long - lost line of Shadowhunters. They bring back an ancient fighting style or a forgotten weapon. This OC could be on a quest to rediscover their family's past and in the process, they end up uncovering secrets about the Shadowhunter world that could change everything. Maybe they find a hidden lair with powerful artifacts that were thought to be lost forever.

A really cool plot for this crossover fanfiction could be that there is a prophecy in both the Twilight and The Originals worlds. It predicts that a certain character from each universe must join forces to save both worlds from a great evil. This could be a dark force that is slowly consuming all supernatural beings. Bella Swan could be the key in the Twilight world, and Hope Mikaelson in The Originals world. As they meet and start to work together, they face many challenges due to the different beliefs and power systems in their respective worlds. Their friends and families from both sides also get involved, creating a complex web of relationships and power struggles.

One plot idea could be that the vampires from Twilight possess some of the superpowers from the Marvel universe. For example, Edward could have Wolverine's healing factor in addition to his vampire abilities. This would make him even more indestructible and add a new layer to his character.

Well, a cool plot could be a love triangle between a Twilight character, a Naruto character, and another from their respective worlds. Say Bella is torn between Edward and Sasuke. Sasuke's brooding nature could be seen as similar to Edward's, but his ninja skills and different moral code would add an interesting dynamic. Also, the clans in Naruto could have some sort of connection to the vampire covens in Twilight, like they share a long - lost ancestor who had both ninja and vampire - like abilities.

One plot idea could be that Bella Swan, from Twilight, gets lost in Gotham City. Batman discovers her and at first suspects she's part of some new vampire plot in his city. But as he gets to know her, he realizes she's just a lost girl with her own set of supernatural problems. Another idea is that the Cullens move to Gotham for some reason. Edward and Batman cross paths and Edward's mind - reading ability both intrigues and annoys Batman. They could end up working together to stop a new breed of super - vampires that are terrorizing the city.

One idea could be that Naruto is somehow transported to the Twilight universe. He might mistake the vampires for some sort of new enemy ninjas. And the vampires could be intrigued by his strange powers. For example, his shadow clone jutsu could really puzzle them.

Well, for a Twilight and It crossover fanfiction, you could start with the setting. Suppose the town of Forks is somehow connected to Derry. The vampires in Twilight are often in search of new territories. What if they stumble upon Derry which has its own dark secrets in the form of Pennywise? The Losers Club could initially be terrified of the vampires, thinking they are some new form of evil. But then they realize that they might need to work together to defeat Pennywise who sees the vampires as new prey. It could be a story full of mystery, horror, and unexpected alliances.
