One possible reason could be that Dumbledore wants Harry to have a more normal upbringing away from the spotlight of Hogwarts and his own influence. So he deliberately steps back from the role of guardian.
One reason could be that Dumbledore had too many other responsibilities in the wizarding world. He was the headmaster of Hogwarts and was constantly involved in dealing with the threat of Voldemort on a larger scale. He might not have been able to give Harry the individual attention and care that a true guardian should provide.
Perhaps Sirius Black could be Harry's magical guardian instead. In the original story, Sirius had a strong connection to Harry and a great desire to protect him. Even though Dumbledore was a major figure in Harry's life, Sirius was his godfather and had a natural claim to the role of guardian.
Dumbledore, as Harry's guardian in the fanfiction, would probably use his influence in the wizarding world. He could make sure that Harry is taught by the best teachers at Hogwarts. He'd also be there to offer advice and guidance, especially when Harry faces challenges like dealing with Voldemort or other dark forces. For example, he might teach Harry some advanced defensive magic privately to better protect himself.
Yes, there might be. In the vast world of fanfiction, all sorts of creative and unexpected scenarios are explored. Some authors might come up with the idea of Dumbledore being afraid of Harry for various reasons. It could be due to Harry's newfound power that he doesn't fully understand, or perhaps a prophecy that takes an unexpected turn in the author's interpretation. Fanfic writers often like to play with the established characters' emotions and relationships in unique ways.
There could be several reasons. It could be related to the target audience, marketing strategies, or even potential legal and ethical concerns. Also, it might not fit the overall tone or theme the creators have in mind for the franchise.
One possible reason could be that Harry discovers some secrets that Dumbledore has been keeping from him. Maybe Dumbledore has been making decisions about Harry's life without his knowledge, like how he was set up to face Voldemort. This lack of transparency might lead Harry to lose trust in him.
One possible reason for Dumbledore lying in fanfic could be related to his own past mistakes. He may have thought that by not telling Harry everything, he could guide Harry more subtly towards the ultimate defeat of Voldemort. However, this often creates a sense of betrayal for Harry in the fanfic, which adds a new layer of drama to the story.
