Fanfiction about Harry Potter as a Holy Dragon Slayer: What are some interesting plot ideas?

Well, a great plot for this fanfiction could be that the Ministry of Magic is secretly breeding monsters for some dark purpose. Harry stumbles upon this and decides to become the monster slayer to put an end to it. He might face many challenges, such as being hunted by the Ministry's aurors who are trying to protect this secret. Also, he could encounter a monster that has the ability to change its form, making it extremely difficult to track and fight. Harry would need to use his intelligence and the help of his friends to overcome this.

One idea could be the Holy Warrior having unique magical abilities that are different from the regular magic in the Harry Potter world. For example, they might be able to purify dark magic on a large scale.

One interesting plot idea could be a crossover where the Phoenix Slayer magic is introduced into the Harry Potter world and a character has to learn this new form of magic to defeat a dark wizard. Maybe the Phoenix Slayer magic can control the power of phoenixes in a different way than what is known in the original Potterverse.

It could be a dark wizard who wants to control the holy dragon for his own evil purposes. He might see the dragon as a weapon to take over the wizarding world.

The plot could involve Harry discovering a prophecy that links his destiny to slaying a powerful dragon. So, he embarks on a journey to find and defeat it. Along the way, he might have to learn new spells or combat techniques specific to dragon slaying.

One idea could be that Harry discovers a hidden spellbook in Hogwarts that contains ancient spells specifically for slaying the undead. He then has to secretly practice these spells while also dealing with his regular schoolwork and the threat of Voldemort.

Perhaps a story about a group of outcast students who form a secret society dedicated to monster slaying. They are not the typical popular or top - performing students at Hogwarts. Instead, they are misfits who have been bullied or overlooked. But together, they use their combined skills and the power of friendship to take on the most terrifying monsters in the wizarding world.

One idea could be a story where Harry discovers he has an ancient dragon knight heritage. He then has to learn the ways of the dragon knights in secret while still dealing with Voldemort. Another could be that a dragon knight from the past is reincarnated as Harry, and he has to use his past skills to fight new threats at Hogwarts.

One idea could be a story where a young wizard discovers an ancient dragon egg in the Forbidden Forest. He secretly raises the dragon and they form an unbreakable bond. As the dragon grows, they face challenges from Hogwarts faculty who fear the dragon's power. But together, they prove that the dragon can be a force for good.

Well, in some fanfiction, the dragon fire might be used to create a new potion ingredient. For example, a young wizard discovers that by collecting the ashes of a dragon's fire when it burns a certain magical plant, it can be used to make a potion that gives temporary invisibility. Also, perhaps a dragon's fire could be used to melt a cursed object that no other magic can affect, leading to a whole new adventure for the characters.
