A common reason could be misinterpretation of his motives. Fanfic authors may not get his intentions right and make him seem more malicious than he actually is in the books.
Well, in many Harry Potter fanfics about Albus Potter in RADS (I assume it means something like the Ravenclaw, Gryffindor, Hufflepuff, Slytherin system), Albus often faces unique challenges. He might be under a lot of pressure because of his famous father, Harry Potter. In some fanfics, he struggles to find his own identity within the school's sorting system and among his peers. He could be trying to prove that he's not just living in his father's shadow.
A fanfic that stands out is 'Albus Severus Potter: The Time - Turner Quest'. It's about Albus finding a time - turner and going on a journey through time to understand the past of Hogwarts and his family. It's a really creative take on his character. 'Albus Severus and the Cursed Vaults' is another good one. It has elements similar to the 'Cursed Vaults' storyline in the 'Hogwarts Mystery' game but focuses on Albus's adventures. And 'Albus Severus Potter: The House Unity' shows how Albus tries to bring unity among the different houses at Hogwarts, which is a really positive and interesting concept.
Yes, he might. Fanfics can offer different perspectives on the Harry Potter world, and Albus could be interested in exploring those alternative stories.
One possible fanfic could be about Albus Dumbledore's early days as a prefect. He might use his position to explore the hidden corners of Hogwarts. Maybe he stumbles upon a secret passage that leads to an ancient chamber filled with forgotten magic.
Maybe Albus has done something dangerous or disobeyed Harry's instructions. For example, if Albus got involved with some dark magic related stuff without Harry's knowledge, that would surely make Harry yell at him.
One possible reason Albus has haters in fanfic is that fanfic writers sometimes like to explore darker or more complex sides of characters. Albus, being a complex figure already, might be depicted in ways that are unappealing to some fans. For instance, if a fanfic delves into his past mistakes and over - emphasizes them, or if it shows him as being power - hungry in a way that doesn't seem in line with his more positive aspects in the official story. This can lead to a negative perception of him among some readers of fanfic.
Albus Potter could react in various ways. He may feel a sense of protectiveness over his family's story. If a fanfic is respectful and well - written, he might appreciate it. However, if it distorts the facts or portrays his family in a negative light, he would probably be angry. He might also be intrigued by the new ideas and concepts that the fanfics introduce to the wizarding world he already knows so well.
It would be a really interesting experience. Albus Potter, being Harry Potter's son, would have a unique perspective. He might find some fanfics that expand on his father's adventures in ways he never thought of. He could be both amused and perhaps a bit critical, comparing the fan - created stories to the real events he's heard from his family.
