A possible plot might involve the 'father of vampires' being a key figure in a prophecy that Harry discovers. The vampire has the power to either save or destroy the wizarding world. It turns out that he has his own motives and desires that are not entirely clear at first. He may be trying to gain control over the vampire population in the wizarding world, which has been growing out of control. Harry and his friends have to figure out whether to trust him or not as they try to prevent a war between wizards and vampires that could be catastrophic for both worlds. They also learn about the true origins of vampires in the Harry Potter universe through their interactions with the 'father of vampires'.
Yes, there are likely fanfictions out there with the concept of the 'father of vampires' in the Harry Potter universe. Fanfiction writers often come up with creative and unique ideas that blend different elements of the HP world. You can try searching on fanfiction websites like FanFiction.net or Archive of Our Own to find such stories.
One possible plot could be that Harry discovers he has a hidden connection to the vampire world and is actually the heir to the 'King of Vampires'. He then has to balance his life at Hogwarts with his newfound vampiric identity, facing challenges from both the wizarding world that may fear him and the vampire world that may have its own power struggles.
Maybe the fanfiction could focus on Harry as a father dealing with the pressure of his kids being in different Hogwarts houses. For example, if one of his kids was sorted into Slytherin, he would have to overcome his own prejudices from his school days and support his child wholeheartedly. He could also teach them about the importance of unity between the houses.
Well, it could be that Harry Potter, being adopted by the vampires led by Lord Vampires, has to adapt to their nocturnal lifestyle. He might learn special vampire skills like super speed or mind - reading among them. And there could be a struggle as he tries to balance his wizarding world values with the new vampire - centric ones.
In this fanfiction, it could start with an experiment in the magical research of both universes. Harry Potter, while exploring new magic, accidentally creates a portal to the world of Kotomine. Finding the young Kotomine in a difficult situation, Harry decides to stay and help him. As time passes, Harry imparts his knowledge of friendship, love, and the power of good magic to Kotomine. Their relationship grows, and they face various threats together, including enemies from both the Harry Potter and Fate universes who see their relationship as a threat to the established order. Harry's role as a father figure would be central to Kotomine's development, and they would embark on a journey of self - discovery and adventure.
One possible plot could be that a character, perhaps an unknown wizard, is revealed to be the 'Father of Monsters' in the Harry Potter universe. He could be creating new and dangerous creatures secretly, and Harry and his friends stumble upon this mystery during one of their adventures. Maybe these monsters are being used to disrupt the wizarding world's peace, and it's up to Harry to stop this 'Father of Monsters' and his evil plans.
In this fanfiction, perhaps there's a spell or some dark magic at play that has misled Harry all his life about his father. It could lead to a whole new adventure as he tries to find out the truth. He might have to face some old enemies of his real father or make new allies in the process of uncovering his true heritage.
Perhaps some well - known vampire characters from other vampire - related stories could be incorporated. However, they would need to be adapted to fit into the Harry Potter universe. For example, a vampire like Lestat from 'The Vampire Chronicles' could be reimagined as a character in this fanfiction. He could bring his own brand of charm and danger to the story.
One possible plot could be that Harry grows up with unique vampire abilities. Maybe he has enhanced speed and strength like his vampire guardians. He might also struggle with the vampire lifestyle, like having to drink blood in some form while still having his own moral compass.
One possible plot could involve Harry Potter's father, James Potter, having some sort of encounter with a Murkrow (which is a Pokémon) in a fanfiction world where the boundaries between the Potterverse and Pokémon are blurred. Maybe the Murkrow has some special power or knowledge that James needs. As for Dokuro, if it's a character from a different series, it could be that this character is brought into the story as an ally or an enemy. For example, Dokuro could be a magical being from a different realm who tries to either help James achieve a goal or stop him from doing something dangerous.
