Another plot could involve Jasper and Edward going on a journey to discover more about their vampire origins. Along the way, they encounter ancient vampires with secrets that could change the way they view themselves and their place in the vampire world. They face numerous challenges and have to rely on each other's strengths.
In some fanfictions, there might be a plot where Jasper and Edward have a falling out over different views on the vampire lifestyle. Edward is more reluctant to embrace his vampire nature fully, while Jasper, with his military background, has a different perspective. This conflict can lead to a lot of character development for both of them as they try to resolve their differences.
The theme of friendship also pops up often. They have different personalities - Edward is more brooding while Jasper has his own set of experiences. Fanfictions explore how they become friends and support one another. In some stories, they might have differences at first but then grow to understand and respect each other more deeply. This is shown through various situations like dealing with a new vampire in town or handling human - vampire relations in Forks.
Often, antagonists are also important characters in jasper hale and edward cullen fanfiction. These could be rival vampire clans or individual vampires with malicious intents. They create conflict for Jasper and Edward, forcing them to use their powers and work together. The presence of these antagonists can drive the plot forward and also show different aspects of Jasper and Edward's personalities as they face these threats.
One great piece of Edward Cullen and Jasper Hale fanfiction is 'The Unlikely Bond'. It delves into their relationship in a way that shows their mutual respect and how they support each other within the Cullen family dynamic. Another interesting one is 'Beyond the Glare' which explores their different perspectives on being vampires and how that affects their interactions.
Another trope is the 'romantic triangle' or 'quadrangle'. You might have a situation where a female character (maybe from either world) has feelings for both Edward or Jasper and Harry. This can lead to a lot of jealousy, competition, and complex relationship dynamics. It also gives the writer a chance to explore different kinds of love - the passionate, almost obsessive love in 'Twilight' and the more friendship - based love in 'Harry Potter'.
One common plot could be Jasper struggling with his vampire instincts around Bella in a more intense and romantic way. For example, in some fanfictions, he might be extra protective of her in a dangerous situation within the Twilight -esque world, which heightens their emotional connection.
Some fanfictions explore a romantic relationship between Rosalie and Edward, which is a huge departure from the original story. In these, they might discover a deeper connection that was hidden beneath their previous interactions. Writers often create complex backstories and emotional arcs to make this relationship believable, like having them realize they were attracted to each other long before they met Bella.
There are ones where they switch roles. Rosalie takes on Edward's more brooding and reserved nature while Edward becomes more outgoing like Rosalie. It's an interesting take on their personalities.
I really liked 'Edward and Rosalie: Unseen Moments'. This fanfiction focuses on their shared experiences in the Cullen household. It gives a fresh perspective on their friendship and how they deal with the challenges of being vampires together. There are some really interesting dialogues that bring out their personalities.
One possible plot could be about Edward Cullen's early days as a baby vampire. Maybe he shows some unique powers even as a baby in diapers, like being able to communicate telepathically with his family in a very basic way. Another could be his relationship with his parents in this infant state, how they take care of him and his special needs.
One interesting plot could be Harry Potter and Jasper Cullen teaming up to fight a new dark magic threat that combines the wizarding world's dark arts and the vampire world's powers. They use their unique skills, Harry with his magic and Jasper with his ability to sense and manipulate emotions, to outwit the enemy.
