Who are the main antagonists in the 'Edward and Bella having a baby fanfiction'?

The Volturi could be antagonists. In the Twilight universe, they are the powerful vampire coven that enforces vampire laws. They might see the baby as a threat to their power or a violation of their rules. They could try to eliminate the baby or control Bella, Edward, and their family.

In some cases, there could be a new vampire or a shape - shifter who enters the prison and has a vendetta against Edward or Bella. This character would then be a major antagonist, constantly trying to harm them and prevent them from achieving their goals of getting out of prison or finding justice.

It could be that some of the humans who have discovered the existence of vampires and the new baby become antagonists. They might form a group to hunt down the Cullens and the baby, fearing that the baby could be the start of a new vampire - human hybrid race that could overpower humans.

Maybe there are some powerful and corrupt humans in the gang wars. They are not afraid of vampires and want to take over the territory that Edward's family has been protecting. These humans could be the main antagonists as they constantly create trouble for Bella and 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.

In some fanfictions, other vampires outside the Volturi who oppose Bella and Edward joining the Volturi could be antagonists. They might fear that Bella and Edward's new alliance will give the Volturi too much power. These vampires could then plot to stop Bella and Edward from fully integrating into the Volturi.

Well, one possibility could be that the baby has some special powers right from the start. Maybe it can communicate with the vampires in a unique way that no other vampire - human hybrid has before.

Well, it could be about how Bella and Edward adjust to parenthood. Bella might struggle with her new role as a mother while still being a new vampire. Edward, on the other hand, could be overly protective. Their relationship might also change as they focus more on their baby's needs.

The baby would also be a significant character, even if it might start as a newborn. Its presence changes the dynamic between Bella and Edward and influences the actions and decisions they make throughout the fanfiction. And depending on the plot, other characters like Jacob or members of the Cullen family could also play important roles. For example, Carlisle might be involved in providing medical knowledge about the unique situation of the baby. Or Jacob could be there to offer protection from the werewolf side, given his connection to Bella and his pack's loyalty.

Obviously, Edward and Bella are the main characters. They are the parents in this fanfiction. And of course, their baby is also a very important character, even though it may not have a name yet in some versions of the fanfiction.
