Can you recommend some good 'Harry Potter Demon Lord fanfic'?

Well, 'A Sirius Adventure with Harry' is quite interesting. In this fanfic, Sirius and Harry embark on a quest that was not part of the original story. It's full of action and their relationship is portrayed in a very heartwarming way. There's also 'The Protector and the Protected', where Sirius's role as Harry's protector is magnified and they encounter various magical creatures along the way.

There's a fanfic titled 'Harry's Transformation into the Demon Lord'. In this story, Harry discovers his connection to demon lord powers after a strange encounter. It follows his struggle to control these new powers while facing opposition from his friends and the wizarding society at large. It delves deep into how his character changes and the moral dilemmas he faces.

Power struggle is a common theme. The demon lord often represents a powerful and menacing force, creating a power imbalance in the wizarding world. Characters then have to either resist or be tempted by this power.

I really like 'Demon - Haunted Harry'. In this one, Harry is haunted by a demon from his past. The author does a great job of building suspense as Harry tries to figure out how to get rid of the demon and what it really wants from him.

One popular demon Harry Potter fanfiction is 'The Demon's Heir'. In this story, Harry discovers he has a demonic heritage that changes his path at Hogwarts completely. It has some really interesting twists on the original plot and characters.

One popular 'Harry is a Lord' fanfic is 'Harry Potter: Lord of Hogwarts'. It explores a different path for Harry where he takes on more of a lordly role within the wizarding world. He has to deal with new political situations and power dynamics.

Sure. 'The Redemption of the Dark Lord' is an interesting fanfiction in this genre. It presents a scenario where Voldemort has a change of heart. It's a really unique take on his character. 'Dark Lord's Ascent' is also quite good. It details the rise of Voldemort in a different way than the original books, adding more backstory and depth to his character. And 'A World with the Dark Lord' gives a vivid description of how the magical society would be if Voldemort had always been in power.

I've also heard of 'Potter and the Devil's Legacy'. This fanfiction imagines a scenario where there are hidden secrets in the Potter family's past related to Lord Sparda. As Harry delves deeper into these secrets, he uncovers a world of dark magic and ancient prophecies. It's a very engaging read as it keeps you on the edge of your seat with all the mystery and the new take on the Harry Potter lore with the addition of Lord Sparda elements.

One great 'Harry Potter Lord of Atlantis' fanfiction is 'The Atlantis Connection in the Wizarding World'. It weaves an interesting plot where the magic of Harry Potter's world intersects with the mystery of Atlantis. Another one could be 'Harry Potter's Atlantis Adventure' which takes Harry on an unexpected journey to the lost city.

One popular 'Time Lord Harry Potter fanfiction' is 'The Time - Traveling Wizard'. It has an interesting plot where Harry discovers he has Time Lord abilities and uses them to change certain events in the wizarding world.
