Well, if Harry Potter finds the Mask of Zen - Aku, it could lead to a lot of chaos. Maybe the magic of the mask would interact in strange ways with Harry's own magic. He might struggle to control the power of the mask and find himself in situations where he has to make difficult choices between using the mask's power for good or being corrupted by it.
One possibility is that the mask could give Harry new abilities that he has to learn to master quickly. For example, it could enhance his spell - casting in ways he never expected. However, the dark nature of the mask might also attract dark wizards who want to take it from him. So, he would have to be constantly on guard while also trying to figure out the true nature and origin of the mask.
Perhaps the mask has a connection to an ancient and forgotten magic in the Harry Potter universe. Harry, being the curious and brave wizard he is, would surely try to uncover this connection. He might seek the help of his friends like Hermione and Ron. Hermione would likely start researching in the library to find any mentions of the mask, while Ron would be there to support Harry in case of any immediate danger. The discovery of the mask could also change the power dynamics in the wizarding world as other characters react to Harry having this new and potentially dangerous item.
The mask could potentially strain Harry's relationships. His friends might be worried about him using the mask and getting corrupted. For instance, Hermione could be very cautious and try to persuade Harry to get rid of the mask. This might cause some friction between them as Harry might be more curious about the mask's power.
Well, in such a fanfiction, Harry Potter might discover a magical mask with special powers. It could be a mask that allows him to see through disguises, like those used by Death Eaters. Maybe it was left behind by an ancient wizard and holds the key to some long - forgotten mystery in the wizarding world.
Well, if Harry Potter finds Excalibur, it could completely change the wizarding world. He might gain some new powers from the sword. Maybe he could use it to defeat Voldemort in a more epic way than with his own wand. It could also bring a new alliance between the wizarding world and some other magical beings who respect the power of Excalibur.
Well, he might discover a whole new world of magic in that fanfiction. Maybe it contains spells that are not in the original books. He could get inspired to try out new things or it could even lead him to new adventures within the Hogwarts library, like finding a hidden section related to the ideas in the fanfiction.
One idea could be that the Sword of Zen Aku is hidden in an ancient and forgotten chamber in Hogwarts. Harry discovers an old map or prophecy that leads him to it. Another idea is that the sword has been stolen by a dark wizard and Harry has to track it down. Maybe the sword has the power to control certain magical elements, like the ability to stop a dark curse that's spreading across the wizarding world.
It could be an evil dark wizard. This wizard might have created the mask with the intention of using it for some nefarious purposes, like taking over the wizarding world. But before he could use it, the mask was lost or hidden, and now Harry has found it.
Snape might suspect that there is some dark magic at play. Given his knowledge and expertise in the Dark Arts, he would immediately look into any signs of foul play. He could also be conflicted because on one hand, Harry is a student he has had many issues with, but on the other hand, he is also an important figure in the fight against Voldemort. So he would have to decide whether to report Harry's disappearance or try to handle it privately.
Well, I haven't actually read this specific fanfiction. But generally, it might involve Harry Potter's adventure to discover the Sword of Zen Aku. Maybe he faces a series of challenges and uses his magic skills to overcome them. It could also introduce new characters or settings related to the sword.
He could end up selling the devil fruit. In some fanfictions, devil fruits are extremely valuable and sought - after items. Harry might not want the power or the responsibility that comes with it, so he decides to cash in on it. But this could also attract all kinds of unwanted attention from powerful and dangerous characters who want the fruit for themselves.
In fanfiction, the possibilities are endless. It could be that they go on an adventure to a previously unknown magical land or face a powerful dark wizard who was thought to be defeated.
