A plot could revolve around a new vampire who is innocent of the traditional vampire 'sins' like excessive blood - lust but is judged by the Volturi immediately. The story could then be about the new vampire proving their innocence to the Volturi and also to Bella and Edward's group. It might involve the new vampire having a special ability that is misunderstood at first.
One plot idea could be a vampire being wrongly accused of a series of murders in the Twilight universe. The other characters initially believe the worst, but as the story unfolds, evidence starts to point to a different culprit, perhaps a rogue werewolf or a vengeful human. This could create a lot of tension between the vampire clans and the werewolves as they try to solve the mystery.
By showing the initial misjudgment clearly. For example, if a character is wrongly accused of a crime against vampires or werewolves, show how quickly others condemn them without evidence. Then, gradually introduce the evidence that clears their name. It could be as simple as a witness coming forward at the right time.
One idea could be a crossover with a popular anime like 'Naruto'. The Guilty Gear characters could find themselves in the Ninja world. For example, Sol Badguy could team up with Naruto to fight a common enemy that is causing chaos in both their worlds. Maybe it's a new type of Akuma - like being from Guilty Gear that has the ability to use chakra too.
One interesting plot idea could be exploring how different characters adapt to the post - apocalyptic world in new and unexpected ways. For example, a character who was once a timid office worker becomes a fearless scavenger.
A possible plot could be that the 'guilty leash' is a symbol of Draco's debt to Hermione. Hermione, who has always been an advocate for justice, uses the leash to make Draco do good deeds in the wizarding community. As they work together on these projects, like helping out at Hogwarts or in the wizarding hospitals, Draco starts to see the world from Hermione's perspective and they develop feelings for each other along the way.
A great plot for Until Dawn crossover fanfiction might be a crossover with the Final Fantasy series. The Until Dawn characters could be transported into the world of Gaia or some other Final Fantasy world. They would have to adapt to the magic and the different races there. They could go on quests, fight monsters, and maybe even meet some of the iconic Final Fantasy characters like Cloud or Tifa. Another idea is a crossover with the Silent Hill series. The Until Dawn group would find themselves in the fog - filled, nightmarish town of Silent Hill. They would have to face their inner demons as well as the grotesque creatures that lurk in the town. And they could also cross over with a detective - themed show like Sherlock. The Until Dawn characters would be involved in solving mysteries in Victorian London, with Sherlock and Watson helping them out.
A plot could involve a new vampire in the Twilight universe who is ashamed of their transformation and uses a mask to try and fit into human society again. They struggle with their new instincts while trying to keep their identity a secret. Along the way, they meet other characters from the Twilight series and their story unfolds in a way that challenges the norms of the original story.
One idea could be a new vampire character being reborn in the Twilight universe with a special power, like the ability to control the weather. This would create a whole new dynamic as they interact with the Cullens and other vampires.
One idea could be exploring a new magical creature in the Twilight universe. For example, a magical being that can control time and how it affects the relationships between vampires, werewolves and humans. Another plot could involve a character from the Twilight world getting lost in a different magical realm and having to find their way back, all while facing new and strange challenges.
One plot idea could be a hockey player who discovers he has a special power during a twilight game, like being able to skate at super - speed. Another could be a love story between a hockey fan and a player, set against the backdrop of twilight - filled evenings at the rink. Maybe a story about a hockey team's struggle during the twilight of their careers, with an old - timer coming out of retirement to save the day.
One idea could be exploring the origin of the psychic powers in the twilight world. Maybe there was an ancient event that triggered it.
