Harry Potter himself could be a common character. There could be fanfics where he discovers some hidden creature inheritance within himself that gives him new powers or abilities. Another one might be Hermione. She could be researching about creature inheritances and accidentally stumble upon something related to her own family.
Harry Potter himself is often a central character in such fanfictions. Given his connection to various magical creatures throughout the original series, it's not a stretch to imagine him inheriting something related to a rare creature. Hermione could also be a common character. Her thirst for knowledge might lead her to discover or be involved in a rare creature inheritance. Ron, with his Gryffindor bravery, might also be in the mix, perhaps inheriting a trait from a more combat - related rare creature.
New original characters are also common. These are characters created by the fanfiction authors who might be the sole heir to a long - lost inheritance of a royal creature. They could be an ordinary wizard at first, but then find out they have a connection to a powerful and mysterious royal creature like a basilisk. Their journey to understand and embrace this inheritance forms the main plot of the story.
Some fanfictions may also introduce original characters who are related to known wizarding families. For example, a long - lost relative of the Black family. These characters can bring new perspectives on inheritance. There could also be characters from other magical cultures or regions who have their own unique inheritance systems that interact with the more familiar Harry Potter world inheritance ideas.
Harry Potter himself is often involved. His inheritance from his parents, like the Invisibility Cloak and his family's magical abilities, can be a central part of the story. There could be situations where others suspect he might use his inheritances in a way that betrays the wizarding world, like if he was somehow influenced by the dark side of his family's magic.
Well, in many of these fanfictions, Harry is central to the story as the one whose inheritance is being contested. His friends, as I said, are likely to be involved. But also, there could be some antagonists. For example, some pure - blood families who think they have a claim to the Potter inheritance. Bellatrix Lestrange's family might be one such group if they believe they are entitled to something from the Potter family. And there could be new characters created specifically for the fanfiction who are either helping or hindering Harry in dealing with the inheritance issue.
Draco Malfoy can be a key character too. Maybe he inherits the pride and territorial nature of a dragon - like creature. This would add an interesting dimension to his character, as he would have to deal with this new part of himself while also navigating his family's expectations and his own place in the wizarding world.
There could be new characters introduced as well. For example, an old wizard or witch who has knowledge about the specific creature inheritance Harry has. They could be a mentor figure, teaching Harry how to control and use his newfound abilities. And of course, the antagonists like Voldemort would be affected by Harry's new powers. They might try to find a way to counter or steal Harry's creature inheritance powers.
Harry Potter himself is often a main character. Since he has a connection to Gringotts already through his vault, it's natural for him to be involved in any inheritance - related stories. He might be the rightful heir to a previously unknown inheritance.
It's hard to say without reading it, but it could be the main trio - Harry, Hermione, and Ron. They often get involved in all kinds of magical situations in fanfiction.
In this kind of fanfiction, creature inheritance often works through family bloodlines. If a family has a long - ago connection to a certain creature, like an ancestor who made a pact with a unicorn, that connection might be passed down generations. It could also be triggered by a magical event. For instance, if a character is in a place where a powerful magical creature once lived and a magical energy is released, it could awaken the inheritance.
