Well, it could be that Dumbledore steals Harry's Invisibility Cloak for some 'greater good' he believes in. Maybe he thinks it's too dangerous for Harry to have at a certain point in time.
There would also be fans who are simply curious. They might want to read the fanfic just to see how the author justifies Dumbledore's actions. Whether it's because of some dark prophecy or a misunderstanding, they would be interested in seeing how the story unfolds and if the author can make this rather controversial concept seem plausible within the magical world of Harry Potter.
One possible reason could be that Dumbledore believes he is acting in Harry's greater good. Maybe he thinks that by taking certain items from Harry, he can protect them from falling into the wrong hands. For example, if Harry has a powerful magical artifact that Voldemort desires, Dumbledore might steal it to keep it safe.
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.
The fanfic changes the perception of Dumbledore's character in that it shatters the image of his infallibility. He is no longer the perfect headmaster and guide. Stealing from Harry shows that he is capable of moral wrongs, and this can lead to a more nuanced understanding of his character, where he is not simply all - good or all - bad but a mix of both, with his own motives and desires that might not always align with what is best for Harry.
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.
Yes, there might be. The Harry Potter fandom is vast, and there could be fanfics with all sorts of creative and sometimes controversial plotlines like this. However, not all such fanfics are easy to find or of high quality. You'd need to search on popular fanfic platforms like Archive of Our Own or FanFiction.net.
In the fanfiction, Snape could protect Harry from Dumbledore by using his skills in potions. For example, he might create a potion that hides Harry's magical signature from Dumbledore's detection. Or he could use his knowledge of the Dark Arts to counter any spells or charms that Dumbledore might use to keep tabs on Harry. Snape is very intelligent and resourceful, so he could find various ways to physically and magically shield Harry from Dumbledore.
Well, perhaps one of the other teachers might have noticed Snape's behavior towards Harry and reported it to Dumbledore. It could also be that Dumbledore, being as perceptive as he is, noticed Snape's extra harsh treatment of Harry during their interactions in the corridors or in class.
One possible reason could be that Harry has discovered something about himself or his past that he thinks Dumbledore might not approve of or might try to stop him from exploring further. For example, if he found out some dark magic connection in his family history that he wants to understand on his own without Dumbledore interfering.
