Obviously, Harry Potter himself is a very common character. He's the hero of the original series, so it makes sense he'd be central in fanfictions with a chase theme. Ron and Hermione are also often included as his sidekicks, helping him in the pursuit.
Another character that shows up a lot is Severus Snape. His complex relationship with Harry can add a lot of depth to the story. In a 'catch me if you can' scenario, he could be a wild card, either helping Harry secretly or having his own motives that are not clear at first.
Draco Malfoy can be a common character in these fanfictions too. He can be either an antagonist, trying to stop Harry from achieving his goal in the chase, or he could be forced to team up with Harry in some unexpected circumstances. Then there's Dumbledore, who might be guiding Harry from the background or providing crucial information to help in the chase.
Draco Malfoy is very common. Since he was the one who actually used the vanishing cabinet in the original books, a lot of fanfiction focuses on his motives and actions related to it. Harry Potter himself is also often in these stories. He might be trying to stop Draco from using the cabinet for evil purposes or exploring the secrets of the cabinet himself. Hermione Granger could be another one. Her intelligence might be used to figure out how the cabinet really works or to counter any dark magic associated with it.
Hermione Granger is also a popular choice. Given her intelligence and love for learning about potions, it's easy to imagine her either creating more Felix Felicis or using it in a clever way to solve a problem at Hogwarts.
Hermione is quite common. Her intelligence and inquisitive nature make her a great fit for exploring the strange world of Wonderland. She could analyze the different creatures and situations she encounters.
Hermione Granger is a very common character. Given her intelligence and passion for justice, she often plays a crucial role in political changes in fanfiction. She might use her knowledge to reform the Ministry of Magic or fight for the rights of marginalized groups.
Obviously, Harry Potter himself is very common. He's the central character in the original series, so fanfiction often continues his story or reimagines it. Hermione Granger is also a frequent character. Her intelligence and strong - willed nature make her a great focus for many different storylines. Draco Malfoy is another popular one. Writers like to explore his character further, perhaps showing a more complex side to him than in the original books.
Harry Potter himself is very common. After all, he's the main character in the original series and is likely to be at the center of any apocalyptic events in the fanfiction. Hermione Granger is also frequently seen as she's smart and resourceful, which are great traits in an apocalypse. Ron Weasley is another one, as he's Harry's loyal friend and has his own set of skills.
The new generation of students at Hogwarts are very common in these fanfictions. Characters like Teddy Lupin, who has his own unique backstory being the son of Remus Lupin and Nymphadora Tonks. Also, the Weasley - Potter clan members are frequently seen. And in some fanfictions, there are original characters created by the authors, who interact with the well - known Harry Potter characters and add new dynamics to the story.
Another character that could be common is Charlie Weasley. Since he works with dragons in Romania, he can bring a lot of knowledge about dragons to the fanfiction. He might be called back to Hogwarts to deal with a dragon emergency, or be the one to introduce a new type of dragon to the Hogwarts students.
The main trio - Harry, Ron, and Hermione - are very common. They are the protagonists of the original story and their presence in Malfoy Manor fanfiction can drive the plot forward. Draco Malfoy is an obvious choice as well, as it is his home. Additionally, Lucius Malfoy could be a prominent character. His role as a Death Eater and a father figure in the Malfoy family can add depth to the story. Some fanfictions might also include Luna Lovegood. Her unique perspective on magic could be useful when dealing with the strange and often dark magic associated with the Malfoy Manor.
Ron Weasley is another character that frequently shows up. His insecurities about his academic abilities compared to Harry and Hermione can be explored further in relation to the owl results. For example, he might be really disappointed if his results are much worse than his friends', or he could be overjoyed if he manages to do better than expected. And of course, Draco Malfoy can also be a central character. His family's expectations and his own desire to outdo the Gryffindors could be tied into his owl results in interesting ways.
