Ragnok is a significant figure in the wizarding world, especially in relation to the goblin community. In the 'Harry Potter Saves Ragnok' fanfiction, he is likely in a precarious situation that requires Harry's intervention. He might be a key character in terms of the magical economy or some ancient magical secrets that the bad guys want to get from him. Harry, being the hero, steps in to protect him and whatever secrets or importance he holds.
Ragnok is a goblin in the Harry Potter universe. In the fanfiction, he's the one that Harry is set to save.
Well, in this fanfiction, Harry might use his magic skills and bravery to rescue Ragnok. Maybe he has to face some dark creatures or overcome some tricky spells along the way.
It could be some dark wizards who want to use the centaur's parts for potions. They might be following some ancient, dark magic recipe that requires centaur hair or hooves. So they hunt down the centaur, but Harry gets in their way.
Zoe could be a new student at Hogwarts who gets into trouble. Maybe she's a first - year who wandered into the Forbidden Forest by accident and Harry has to save her from the dangerous creatures there.
The obvious antagonists would be the Death Eaters. They are Voldemort's followers and are often causing trouble in the wizarding world. In this fanfiction, they might be the ones who have put Cedric in danger, either to lure Harry or for some other dark purpose.
It could be an ancient dark magic artifact. The artifact has a hold on Bellatrix, and in a way, it's the 'enemy' that Harry has to defeat to save her. The artifact might be trying to use Bellatrix to carry out some dark plan, like opening a portal to a world full of dark creatures. Harry has to figure out how to break the connection between Bellatrix and the artifact while also fending off the artifact's attacks.
It could be a new character created specifically for the fanfiction. Maybe a vampire who has been living in the Forbidden Forest for years and has stayed hidden until some event brings it to Harry's attention.
Obviously, Harry Potter and the Jedi would be the main characters. Maybe Luke Skywalker and Harry could form an alliance.
Obviously, Harry Potter would be one of the main characters. Since it's about him saving the Flamels. The Flamels themselves, Nicolas and Perenelle, would also be main characters as they are the ones being saved.
It might be a character from a different fairy - tale world that has been magically transported into the Harry Potter universe. Let's say it's Snow White. She retains her beauty and kindness but is now in a world full of wizards and witches. Voldemort or one of his followers wants to use her for some evil purpose and Harry Potter has to save her. He would be quite confused at first but then rises to the occasion.
Voldemort would still be a likely villain. He is the main antagonist in the original series and his threat to Harry is always present. Even if Harry is trying to save himself, Voldemort's power and his desire to kill Harry would make him a formidable foe.
