There could also be new characters introduced specifically for this fanfiction. Maybe a wise old wizard in the afterlife who guides Harry and helps him transition between his two lives. Or a new villain who emerges in Harry's new life, someone who is related to the events of his past life in a complex way.
Well, Harry Potter is surely one of the main characters, as the title implies. His development across two lifetimes would be a central focus.
Well, Harry Potter himself would most likely be one of the main characters. He's the central figure in the original series, so it's reasonable to assume he'd play a big role in the fanfic as well.
Since I haven't read this particular fanfiction, it's hard to say for sure. But it could feature Harry Potter himself, maybe he encounters this 'no life king' character and has to deal with whatever chaos or mystery they bring. It might also include his friends like Ron and Hermione who could be involved in trying to understand or stop the 'no life king' if they pose a threat.
Well, of course, there would be the Auror as the central character. Maybe it's an original character created for the fanfiction. There could also be appearances by well - known characters like Harry Potter himself, who could be a mentor or a colleague to the Auror. And perhaps Hermione, who could provide some intellectual support or be involved in some magical research that the Auror has to protect.
It's likely that the main characters will be the descendants of the well - known characters from the original Harry Potter series. So, in addition to the Potters, the Weasleys' next - gen kids could also play major roles. They might inherit some of the traits and skills of their parents. There could also be new characters from other wizarding families that interact with them and become central to the story as well.
Harry Potter himself would surely be a main character. He'd be the protagonist trying to navigate this new game - like version of his life. Hermione Granger would also be important as she'd use her intelligence to figure out the rules and strategies of the game world. Ron Weasley would be there too, providing comic relief and being Harry's loyal sidekick as always.
In many 'In this world and the next' fanfictions, Severus Snape remains a popular character. His complex past and ambiguous loyalties in the original series make him ripe for further exploration. Fans might write about his experiences in the 'next world' or how his actions in this world are affected by the existence of the other. Another popular character could be Sirius Black. His free - spirited nature and his relationship with Harry are often explored in fan - made stories.
Scorpius Malfoy is often a popular character. He can be shown as a complex character, not just the son of a former Death Eater. He might form an unlikely friendship with a Potter or a Weasley, which makes for an interesting dynamic.
Scorpius Malfoy is often a popular character. His relationship with Albus Potter in the 'next gen' setting is already interesting, and in time travel fanfictions, he can bring his unique Malfoy charm and intelligence to different time periods. He might use his cunning to solve problems that arise during their time - traveling adventures.
Obviously, Harry Potter is the central character. But in this fanfiction, 'life' could be personified as an important character too. It might be some sort of spirit or entity that has a big influence on Harry's upbringing.
Hermione Granger is also a favorite. Fanfic authors might write about her solving complex magical problems or having adventures that the original books didn't cover. She's such a strong and intelligent character that there are endless possibilities for her in fanfiction.
