It could mean that in a Harry Potter fanfic, there's a character who is not considered part of a particular group within the fanfic's story. Maybe he has different values or goals compared to the rest of the characters who are united by something specific in the fan - created story.
Well, in the context of a Harry Potter fanfic, 'he is not one of us' might imply that this 'he' doesn't belong to a certain clique or faction. It could be related to Hogwarts houses, for example. If it's a group of Gryffindors in the fanfic, and 'he' is acting in a way that's not in line with Gryffindor values, then they would say he's not one of them. It could also be about a secret society within the fanfic's version of the wizarding world.
It could be an older wizard who has turned his back on the traditional ways that the group in the fanfic adheres to. Maybe he has discovered a new form of magic that is considered taboo by the others, and so they see him as an outsider, not one of them. He might also be trying to bring about changes in the wizarding world that the group is not ready to accept, such as more integration with non - magical people in the fanfic's story.
Well, 'Harry Potter' is the famous series. 'Trust no one' is a common theme in many stories, especially in a world like Harry Potter's where there are a lot of secrets and betrayals. A 'fanfic' is a fan - created fiction. So it could be a fan - written story in the Harry Potter universe where the main idea is about not trusting anyone.
Well, 'scourgify' is a spell in the Harry Potter universe that cleans things. In a fanfic, 'scourgify power he knows not' could imply that a character is unaware of the full potential or some hidden aspect of the scourgify spell. Maybe it could be used in a more powerful or different way than the character realizes.
It could be Harry Potter himself. He's always been one to help others, especially those in need. He might see a new student being harassed by Slytherins and step in, saying 'one of us will help you'.
It might also imply that the popularity of 'Harry Potter' has waned to the point where fanfic has died off. When the series was at its peak, there was a huge amount of fanfic. But as time passed, if the fan base decreased or moved on to other things, the creation of new fanfic related to 'Harry Potter' could have been significantly reduced.
I'm not entirely sure what 'harry potter is skull fanfic' specifically means. 'Fanfic' is short for fan fiction, which is fictional writing by fans of a particular work. But the combination with'skull' is really strange and unclear in this context. Maybe it's some very unique and creative take within a small group of Harry Potter fans who are into something related to skulls and creating their own unorthodox stories.
It could mean that there is a fan - made fictional work where Harry Potter is somehow related to a puppy. Maybe in this fanfic, Harry Potter has a pet puppy or there are some adventures involving puppies in the Harry Potter - like world.
Well, it could be a very strange or dark take on a Harry Potter fanfic. 'On suppressants' might imply that in this fan - created story, Harry Potter is somehow being drugged or having his abilities suppressed, but it's a really odd and not very common concept in the typical Harry Potter fanfic world.
Perhaps it implies that in this fanfic, the Harry Potter universe intersects with the idea of metahumans. For example, Harry could be re - imagined as a metahuman with powers beyond his normal wizarding abilities. It might be a really creative way to blend two different fictional concepts together, allowing for new and interesting storylines and character developments.
It could mean that within the context of the Harry Potter world, there is an idea or statement where Harry Potter, as a character, is opposed to fanfiction. Maybe it implies that the official or 'true' story as per the original works doesn't want to be overshadowed or misrepresented by fan - created stories.
