One great 'Harry Potter Quirrell fanfic' is 'The True Nature of Quirrell'. It delves deep into his character, exploring his motives beyond what we see in the original books. Another one could be 'Quirrell's Hidden Past' which uncovers secrets about his life before Hogwarts. There's also 'Quirrell's Redemption' that offers an interesting take on if he could have been redeemed.
A really unique part of these fanfics is how they can change our perception of Quirrell. Instead of just seeing him as a simple villain, they can show his inner turmoil. Some fanfics might depict him as a victim of certain circumstances or having a more complex moral compass. Also, the relationships he forms in fanfics can be different from what we expect. He might have unexpected friendships or alliances that add new layers to the story.
Harry had been able to kill Quirrell because Lily had cast a Protection Charm on him to protect him from Voldemort, who had possessed Quirrell at the time, and the Protection Charm had identified Quirrell's body as Voldemort, so Harry had been able to kill him. There was also a theory that Voldemort killed the unicorn and drank its blood to make himself healthy, that the unicorn was a symbol of purity, and that the one who killed it and drank its blood was evil, and that Harry was brave and kind, so he could kill Quirrell with his hands. Harry Potter and the Chamber of Secrets is not enough. Everyone is welcome to click to read the novel!
Perhaps Harry is tricked. Quirrell could be using some sort of mind - influencing magic or deception. He might make Harry believe that giving him the stone is the only way to save his friends or Hogwarts. Harry, being young and inexperienced, might fall for such a ruse and hand over the stone without fully realizing the consequences.
One possible consequence could be that Voldemort, who is using Quirrell, gains more power. Since the Philosopher's Stone has the ability to create the Elixir of Life, Voldemort could use it to create a new body or regain his full strength much faster. This would put Hogwarts and the entire wizarding world in great danger as Voldemort is extremely powerful and evil. He would likely start to hunt down those who oppose him, especially Harry Potter, with even more vigor.
Well, just based on that title alone, it's difficult to determine its quality. There are so many aspects that make a Harry Potter fanfic great. For example, it could explore new relationships between the characters, or create exciting new magical adventures. But we don't know if 'skull is harry potter fanfic' does any of those things. So, it might be good, it might not.
In some fanfictions, they might rewrite the possession scene completely. Instead of the typical way it was shown in the books, they could add new magical elements. Maybe Quirrell has some hidden magic that reacts to the possession, creating a more complex and engaging story.
I really like 'A Dragonborn's Adventure in the Wizarding World'. It combines the lore of both Dragonborn and Harry Potter. The author does a great job of integrating the combat skills of the Dragonborn into the magical battles at Hogwarts. For example, when facing dark wizards, the Dragonborn uses his shouts in unexpected ways to counter their spells.
A great one is 'Quirrell's Hidden Struggle'. In this fanfic, it really shows how Quirrell's personality changes as he gets possessed. You can see the transformation from a timid professor to a more menacing figure under Voldemort's influence. It's interesting to see how the author plays with his character development.
One great Johnlock Harry Potter fanfic is 'The Enchanted Bond'. It combines the mystery-solving elements of Johnlock with the magical world of Harry Potter in a really engaging way. The characters are well-written, and it's interesting to see how Sherlock and John fit into the wizarding world.
I haven't come across many 'Harry Potter Gun Fanfic' myself. However, if you are into this rather unique combination, you could look for fan communities dedicated to Harry Potter fanfics. They might be able to point you in the right direction. Maybe start with the larger ones on social media platforms, where fans often share their favorite finds.
