I really like 'A Different Harry Potter'. In this fanfic, Harry is raised by a different family, which gives him a whole new identity. He has different values and skills compared to the original Harry. Another interesting one is 'Harry Potter: The Time - Traveler'. Harry goes back in time and has to assume a new identity to avoid disrupting the past too much. It's a fascinating read as it weaves in elements of time - travel and alternate identities.
In these fanfics, the theme of adaptation is quite common. Harry has to adapt to his new identity, whether it's a new name, a new magical ability, or a new social standing. Another theme is the exploration of different magical cultures. If his identity is changed in a way that he's associated with a different group, like a foreign wizarding community, it delves into different magical practices. And identity crisis is also a key theme. Harry may struggle with who he is now compared to who he was supposed to be in the original story.
One idea could be that Harry has an alternate identity as a Muggle detective. He uses his magical skills secretly to solve cases that have a magical element but are disguised in the Muggle world. For example, he might be investigating a series of strange disappearances that are actually the work of a dark wizard trying to gather ingredients for a powerful spell.
His appearance and behavior in the alternate identity should be different yet still recognizable as Harry. If he's an undercover Auror in a different country, he might change his hair color with a simple spell, but his determination and quick thinking would still be there. His speech pattern could also change slightly to fit the new identity. He might use different magical tools or spells that are common in that region but still rely on his basic Hogwarts training at the core. This combination of change and familiarity makes the alternate identity believable in the context of a fanfic.
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.
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.
Well, Hermione is often depicted in different ways in these fanfics. In some alternate universes, she could be a powerful dark witch instead of the studious and good - hearted character we know. Ron might be a super - confident and arrogant character rather than the sometimes insecure boy in the original story. Also, Snape could be a completely different person. He could be a jolly and friendly teacher rather than the brooding and complex one we are used to.
One great Harry Potter identity fanfiction is 'The Lost Potter'. It delves into the idea of a long - lost Potter relative who has a unique magical identity. Another is 'Identity Revealed' which focuses on a character's hidden identity within the Hogwarts setting and how it impacts their relationships with other characters. And 'Mystery of the Hidden Identity' is also a good one, full of twists and turns as the true identity of a key character is slowly uncovered.
Well, one interesting concept could be a different Sorting system in Hogwarts. Maybe instead of the traditional four houses, there are new ones based on different magical abilities. Another could be an alternate version of the Ministry of Magic, with different laws and regulations regarding magic use.
One interesting concept could be a world where Voldemort won the war. In this alternate universe, Hogwarts might be a very different place, with dark magic being taught openly. Another concept could be a universe where the houses are not divided as they are in the original. Maybe students are grouped based on different criteria like magical talents other than just bravery, intelligence, etc. For example, there could be a group for those who are good at magical creatures handling.
In an alternate dimension, the main antagonist could be a dark entity that has emerged from the very fabric of the dementions themselves. This entity could be using the Dementors as its minions, controlling them to do its bidding. It would be a powerful and mysterious foe, and Harry would have to discover its true nature and weaknesses in order to defeat it.
