One great 'Harry Potter Takes Control' fanfiction is 'The Power Within Harry' which shows Harry taking control of his destiny in a unique way. It has him making decisions that are different from the original story, like taking charge of his magical training earlier.
Well, it could be about Harry Potter having a kind heart and taking in various 'strays' in the wizarding world. Maybe he takes in lonely or lost magical creatures, or perhaps other students who don't really have a place to belong. It might explore his nurturing side and how these 'strays' change his life or the Hogwarts environment.
Perhaps it's a girl orphan who was found wandering near the Forbidden Forest. She has no memory of her past but shows great potential in potions. Harry feels a connection to her because she seems so lost, just like he once was. So, he decides to take her in as the first orphan in his new orphanage.
Well, perhaps Harry would go to a wizarding beach where he could practice magic without the usual Hogwarts restrictions. He might meet some new magical creatures that are only found near the sea.
Well, in this fanfiction 'harry potter takes his lordship', it could potentially revolve around Harry's journey as he accepts this new lordship. Maybe he has to make difficult decisions regarding the wizarding community. He might face opposition from those who don't want him to have this new - found power. And he'll probably have to use his skills and knowledge, both magical and otherwise, to navigate this new phase in his life. It could also explore how his relationships with his friends like Ron and Hermione change as a result of this new status.
I'm not sure specifically as I haven't read that exact fanfiction. But it could potentially be about Harry Potter having some sort of conflict with Dumbledore and taking actions against him. Maybe Harry discovers some dark secrets about Dumbledore that make him question his leadership and take steps to oppose him in the fan - created storyline.
Well, it could be that the snake is a magical snake that was being hunted by some dark wizards. Harry takes it in out of kindness. The snake then forms a bond with Harry and becomes like his secret helper. For example, it could slither into places Harry can't go and gather information for him.
Maybe it's a Centaur foal that has been separated from its herd for some reason and Harry takes it in. Or a goblin who has been wrongly accused and is on the run. Even a ghost that has been forgotten and left to wander alone could be among the strays that Harry Potter takes in according to this fanfiction.
In this fanfiction, Harry might go to a magical beach. He could enjoy sunbathing while his magic keeps the sun from burning him. He might also meet some new magical creatures that only come out during holidays.
