I'm not entirely sure without more context. 'Percy' could refer to a character, and 'hollow' might imply that the fanfiction lacks depth or substance. It could be that the person making this statement feels the fanfiction about Percy is empty in some way, perhaps in terms of plot, character development, or emotional impact.
Maybe it means the fanfiction centered around Percy is like an empty shell. There's no real 'meat' to it. For instance, if Percy has a certain backstory in the original work, the fanfiction might not build on it or might even ignore important aspects, making it seem hollow.
Maybe a group of rogue demigods who have decided to take over the Hollow for their own purposes. They could be using the resources of the Hollow in a wrong way, like trying to extract its magic to make themselves more powerful. They would be a formidable foe as they have demigod abilities.
One idea could be to explore the hidden parts of the Hollow that the main characters haven't discovered yet. Maybe there are ancient secrets or powerful artifacts there. Another could be to create a new character who is a descendant of a minor god and has a unique connection to the Hollow. They could bring a fresh perspective to the story.
Well, without having read it, it might be centered around some unique concepts related to a Netflix series. It could be a creative take on the show's world, like for example if it's a fanfiction about a Netflix fantasy show, it might create new magical elements or expand on the existing ones. Maybe it focuses on a particular character's backstory that wasn't fully explored in the original series.
It could be about original characters (OCs) in a Hollow - related setting. Maybe it involves creating new storylines, relationships, or adventures for these OCs within the context of the Hollow world. It might include elements like the unique powers of the OCs, their interactions with the existing Hollow characters, or their attempts to navigate the challenges of the Hollow environment.
Well, 'naruto is a hollow fanfiction' might be a really unique take on the Naruto universe. If we consider 'hollow' in a more general sense, like an empty or void - like state, it could be a story that explores Naruto in a state of emotional or spiritual hollowness. Maybe he has lost his purpose or something has made him feel empty inside, and the fanfiction delves into that aspect of his character in a new and creative way.
One great Naruto and Hollow fanfiction is 'Naruto: Hollow Shinobi'. In this fic, Naruto discovers a strange power related to Hollows. It has an interesting plot where Naruto has to learn to control this new power while still dealing with the regular challenges in the Naruto world. The character development is quite engaging as Naruto becomes more complex, having to balance his normal ninja skills with the Hollow - like abilities.
It could be a new character created specifically for this fanfiction. Maybe a powerful wizard who has been in hiding and uses the mask to conceal his true appearance while he moves around Hogwarts or the wizarding world.
