Well, it really depends on how the author writes them, but Draco Malfoy can be a very popular character in this type of fanfiction. In some stories, the reborn character might use a wish to change Draco's personality or his family's stance in the wizarding world. This can lead to some really interesting character development for Draco. Another character could be Dumbledore. The reborn character might wish to have a different kind of relationship with Dumbledore, perhaps getting more guidance from him earlier on, and that makes Dumbledore an important and popular figure in these stories.
Probably the main characters from the original work tend to be popular in fanfiction. They are well - known and have established personalities that writers can build on.
Often in such fanfictions, there will be an antagonist as well. This could be a power - hungry entity in the twilight world who doesn't want the main character to succeed in using their wishes for good.

There might also be some side characters, like the main character's friends from their past life who are somehow connected to the new world and play important roles in the story.
