It could be a dark wizard who wants to use the power of magical creatures for his own evil purposes. He might be trying to control them, or use their parts for dark magic spells. For example, he could be after the horns of unicorns to make a potion that gives him immortality.
One idea could be a story where a new student arrives at Hogwarts with an unknown and extremely powerful connection to magical creatures. This student discovers a hidden group of creatures that are being threatened by a dark force. The main character then uses their unique bond with the creatures to save them, much like Harry Potter often did with his friends against Voldemort.

Well, the basilisk is a very prominent magical creature in Harry Potter fanfic. It's a giant serpent that can kill with a single glance. Fanfic writers often explore its origin and the mystery surrounding it. Also, the centaurs are quite interesting. They are half - human and half - horse, and in fanfics, they can offer unique perspectives on magic and the wizarding world.
Most likely Harry Potter himself would be one of the main characters involved in creating creatures. After all, it's in the title. Hermione might also be involved, with her vast knowledge of magic and creatures, she could contribute a great deal to the process.
Another aspect could be the relationship between the 'Lord of Dark Creatures' and the existing magical world order.

In Harry Potter fanfic, one interesting magical creature is the Occamy. It's a serpentine - like creature with wings and can grow or shrink to fit available space. Another is the Nundu.

And the Thestral, which is often explored in fanfic in more detail, as it's only visible to those who have witnessed death.
In some Harry Potter fanfics, magical creatures like the werewolf might be portrayed more sympathetically. Instead of just being seen as dangerous during full moons, they could be shown as struggling with their condition. For example, a fanfic might focus on a werewolf trying to lead a normal life among wizards.
In some Harry Potter fanfics, you might find unique magical creatures like the Shrieking Shackle. It's a small, furry creature that can emit a high - pitched shriek to stun predators.

These add new and exciting elements to the magical world already established in the original series.
In Harry Potter fanfiction, bird creatures often play interesting roles. For example, the phoenix is a very significant bird creature. It has the ability to be reborn from its own ashes, which symbolizes immortality and renewal. In some fanfictions, the phoenix might be used in different ways compared to the original books.
