Well, I think some of the werewolves could also be special guests. Even though there is a bit of a feud between the vampires and werewolves, in a fanfiction scenario, they could put aside their differences for Bella's wedding. Jacob, who has a complex relationship with Bella, might come to show his support in his own way. And some of the other werewolves who have come to respect Bella over time could also be there. It would be a very interesting dynamic to have both vampires and werewolves at the same wedding, with everyone trying to be on their best behavior for Bella's sake.
In addition to the Cullens and Bella's human friends, in some fanfictions, there could be other vampire clans as guests. The Denali coven might come, since they have some connection to the Cullens. They could bring their own unique charm and perhaps some vampire - specific gifts. Also, there might be some ancient vampires who have heard about Bella and Edward's story and are intrigued enough to attend. They could add an air of mystery and danger to the wedding, but also show that Bella and Edward's relationship is something that has caught the attention of the entire vampire world.
Definitely the other members of the Cullen family would be special guests. Carlisle and Esme, who are like parents to Edward, would be there to support them. Alice would probably be super involved in the wedding planning and be a very enthusiastic guest. Jasper might be there to keep everyone calm in case there are any tense moments. Also, Bella's human friends like Jessica and Angela could be special guests. They would be there to witness Bella's big day and share in her joy.
In this fanfiction wedding, not only their friends but also some of the heroes they've worked with in the past could be guests. Rena Rouge and Carapace would be there, having played important roles in many battles. Maybe even some of the one - time heroes like Pegasus or Viperion could show up. Ladybug's parents would be there with open arms, and Adrien's bodyguard could also be present, having seen Adrien grow up. And Paris itself could be considered a 'guest' in a way, as the city has been a big part of their lives and the reason for their superhero existence.
It could be a character named Jake. He's a very competitive Bakugan brawler who sees Bella as a threat because she's quickly rising in the ranks. He's always trying to one - up her in battles and spread rumors about her to make other brawlers not trust her.
Edward could be one of her allies. He could use his vampire abilities such as super - speed and strength to assist Bella in dangerous situations. His centuries - old knowledge could also prove invaluable in understanding the motives and actions of the CIA's enemies. Another ally could be Jacob. His shape - shifting abilities would give the team an extra edge in combat or in covert operations. He could also use his connection to the werewolf pack to gather information from areas that the CIA might not have easy access to.
Perhaps it's a human with a very strong psychic ability. He is drawn to Bella because he can sense her connection to the supernatural. Their relationship could be based on mutual understanding of the secrets they both hold, and Bella might find his normalcy in some ways refreshing compared to her previous relationships with vampires and werewolves.
Obviously, Edward Cullen and Bella Swan are the most important. Edward, the vampire, is central to the story as Bella's groom. Bella, the human - turned - vampire - later in the original series, is the bride. Then there's Alice Cullen. She is often a key character as she loves to plan events and would be all over the wedding preparations. Jasper Cullen might also be important as he could help keep the emotions in check during the big day. And of course, Charlie Swan, Bella's father, his presence or his thoughts about the wedding could be a significant part of the fanfiction.
It could be a new vampire. Maybe a vampire from a different coven who comes to Forks and is immediately attracted to Bella's unique scent and her strong - willed personality.
Well, his family members would surely be there. His parents, Harry and Ginny Potter, would be front and center. His siblings would also be in attendance, like Albus and Lily. And of course, his grandparents on both sides. Then there are his friends from Hogwarts. His best mates from Gryffindor would be there, perhaps Neville Longbottom if he's still in touch. Also, some of the professors who had a big impact on his life, like McGonagall, might be invited as well.
Obviously, their close friends from Hogwarts would be there. Ron and Hermione would be among the guests, as they are Harry and Ginny's best friends. The Weasley family in its entirety would be present too, including Molly and Arthur. Luna Lovegood would surely be invited, with her unique charm. And Hagrid, who has been like a father figure to Harry in a way, would also be there to celebrate this happy occasion.
The guests would include their closest friends and allies. Nico would be there, having finally come to terms with Percy and being part of their group. Rachel Elizabeth Dare would be there as well, since she has a connection to both of them. The centaurs from the forest around the camp would also be invited, like Firenze, who has always been a bit of a mentor figure. And the minor gods and goddesses who have helped them on their adventures might also make an appearance.
Professor McGonagall might be an honored guest. She has seen Harry and Hermione grow from students to heroes of the wizarding world. Her presence would be a symbol of the connection between their past at Hogwarts and their new future. And Dumbledore's portrait, if it has the ability to interact with the living on such an occasion, could also be considered a special guest, as he has played such a significant role in their lives.
