Edward in Twilight fanfiction is typically depicted as having an intense internal struggle. His love for the human girl is always at odds with his vampire instincts. He may be more conflicted in fanfiction than in the original books, as authors explore different scenarios. For example, some fanfics might show him having to choose between his family and his love in a more extreme way. Also, his relationship with other vampires can be further developed in fanfiction, showing his loyalty or lack thereof in different situations.
One great fanfiction could be where Edward and Bella's relationship is explored more deeply in a different vampire society setting. For example, they might be in a vampire clan that has unique rules about human - vampire relationships.
Love is a very common theme. Their intense, often obsessive love for each other is a central part of most fanfictions. Another theme is the struggle between Bella's humanity and the vampire world she's drawn into. Also, the idea of family, like Edward's vampire family and how Bella fits into it.
A common theme is the 'what - ifs'. What if Bella had chosen Jacob instead? Fanfictions often explore this alternative storyline and how it would affect the vampire - human relations in Forks. It can be really interesting to see how the characters develop in this different scenario.
Love and loyalty are very common themes. Edward might have to choose between his love for someone and his loyalty to his vampire kingdom. Also, the theme of identity is prevalent. He has to balance being a vampire prince with his own individual desires and values. Additionally, the idea of sacrifice often comes up. He may need to sacrifice his own happiness for the greater good of the vampire community in some fanfictions.
In most Edward Vampire King fanfictions, Edward is the central figure. However, new characters can be introduced. For example, there could be a powerful vampire named Victor who is a rival to Edward for the throne. And then there's always the possibility of a human character who gets caught up in the vampire world, like a journalist named Lucy. She might be trying to expose the vampire king or end up falling in love with him. Additionally, Edward's vampire siblings play important roles, such as Emmett who can be his bodyguard or Jasper who helps with diplomatic relations.
Maybe a witch who has a vendetta against vampires in general. She could use her magic to cause all sorts of trouble for Edward, like casting spells that prevent him from using his vampire abilities or even creating illusions to drive him mad. Since she's a witch, she has different powers compared to a normal vampire hunter, so she'd be a very formidable antagonist. She might also be able to manipulate other humans or vampires to do her bidding in her quest to get rid of Edward.
Often, other vampire clans that oppose Bella's transformation can be the main antagonists. They might see her as a threat to the vampire world order. For example, a traditionalist clan that believes humans should not be turned so easily could try to harm Bella or drive her away from Edward.
One common theme is the exploration of their eternal bond. Since they are vampire mates, their connection is supposed to last forever, and many fanfictions focus on how they maintain and strengthen this bond. Another theme is the challenges they face due to their different natures. Bella was once human, and becoming a vampire brings a whole new set of issues. Also, the theme of protecting each other and their family is quite common. They are mates, so they will do anything to keep each other safe.
There's a fanfiction called 'Edward, the Vampire King: A New Era'. In this story, Edward as the king tries to modernize the vampire kingdom and face the resistance from the traditional vampire families. Then there is 'The Trials of Edward, Vampire King' which shows his struggle against external threats to his kingdom, like werewolf packs and other vampire clans. Also, 'Edward's Rule' is a story that details his day - to - day ruling and the relationships he forms with his subjects.
