Another plot could be that Harry is given a mission by Dumbledore from beyond the grave. This mission is to find and protect a powerful magical artifact that has the potential to either save or destroy the wizarding world. Along the way, he has to deal with new enemies who are also after the artifact and some of his old friends might turn against him because they think he's become too obsessed with the mission.
Well, in some fanfictions of 'Harry Potter Once Too Often', there could be a plot where Harry discovers a new magical ability that was overlooked in the original series. Maybe he can communicate with magical creatures in a much deeper way, like having full conversations with thestrals and understanding their thoughts and memories.
One interesting plot might involve time travel gone wrong. Harry could accidentally travel back to a time when Voldemort was at his most powerful and has to find a way to return to his own time without being detected. He might have to rely on some old and forgotten spells and the help of some unexpected allies, like a young Snape who doesn't yet know who Harry is.
Obviously, Harry Potter himself is often a central character. His friends like Hermione Granger and Ron Weasley also frequently appear. In some fanfictions, they might play different roles compared to the original books. For example, Hermione could be the one who stumbles upon a dark secret first and has to convince Harry and Ron to take action.
Maybe it's a group of Slytherin students who have it out for Harry. They could be jealous of his fame or just don't like his Gryffindor ways.
I'm not sure specifically as I haven't read this exact fanfiction. But generally, it might be about Harry being repeatedly hurt by certain characters in the Harry Potter universe, and perhaps his journey of dealing with that pain, whether it's through revenge, self - discovery, or finding new allies.
One possible reason could be Dumbledore's over - reliance on his grand plans. He might have been so focused on the big picture of defeating Voldemort that he overlooked Harry's immediate emotional and mental needs. For example, Harry had to face many traumas alone, like the death of Sirius, and Dumbledore didn't always provide the support Harry really needed at those crucial moments.
In some Harry Potter 8 fanfictions, there are plots where the characters continue to face new dark magic threats. For example, a new dark wizard might emerge, and Harry, Hermione and Ron have to use their combined skills and knowledge to defeat this new foe. Another plot could be about the exploration of the wizarding world's past in more depth, revealing secrets that were previously unknown.
One interesting plot could be about the Potter family's hidden secrets being unearthed. Maybe there are ancient spells or prophecies related to them that no one knew before. Another could be a story where the Potter family has to face a new and powerful dark force that is specifically targeting them due to their legacy. And a third plot might involve time - traveling within the Potter family's history to correct past mistakes or learn from them.
In some fanfictions, there are plots that explore the backstories of the less - known characters in the Harry Potter and Legacies universe. For example, a story might focus on the family history of a minor wizarding family and how their actions impact the events at Hogwarts in the present day. It could involve long - lost family secrets, old feuds, and unexpected alliances.
One interesting plot could be the Marauders' adventures during their school days that were not fully explored in the original books. For example, their pranks on other students and how they managed to create the Marauder's Map. Another could be a story where the Marauders interact with Harry in a time - travel scenario, giving him advice and helping him face Voldemort in a different way.
One interesting plot could be a new adventure where Harry discovers a hidden magical artifact in the Forbidden Forest that has the power to change time. This could lead to him having to make difficult decisions about whether to alter the past.
Perhaps in the fanfiction, there are some unique magical creatures involved in Harry's labor. For example, a hippogriff might be there to offer some form of protection or assistance, which would add an exciting and different element to the story.
