Lucius creatively tries to stop Harry from inheriting the Black Headship, only just too late. Harry has no idea why or how, but he is pretty sure he once again barely evaded death. If only he didn't have to become a woman to do it... Given recent revelations, he decides to roll with it and tries to reinvent himself to some success. As a she, he figures the prophecy is a dud anyway.
This is PORN, with a bit of plot. There's a futa, and it's a F/M/F/F situation. Due to a marriage law, Harry get's matched with Millicent Bulstrode. Daphne Greengrass sees her chance and manipulates Harry into a very restricting contract, making him her sex-toy. Some rituals later, and that designation is pretty much literal. At first he hates it, but soon he begins to see benefits
Harry's genius has always been stifled, only used to efficiently do as little as humanly possible. Why, because he realised that nobody would appreciate his efforts at Privet Drive. Now that he is free, he bends his power towards the Greater Good of Mankind. His motto, to do as little as possible to achieve the best outcome. One group at Hogwarts recognised his genius and profit.
Lily Evans was adopted, now so does Harry, only he does it as Sirius' daughter instead of his son in order to protect himself and for various other reasons including betrayal. Living undercover proves to be much safer than as Harry, but the decision to flee the country is still made. This is Luna/Lyra (HP) femslash.
Petunia saw an opportunity and took it. Teaching Jasmine magic for her own gain, she changed the fate of entire Magical Britain. Before going to Hogwarts, Jasmine learned Occlumency and wandless magic. Her entire personality changed to reflect her different circumstances. She tries and fails to make friends, due to circumstances out of her control. She takes those lessons to heart.
Dementors on Privet Drive, what's next? Well, Harry finds his mum's words written specifically for him. In it, he learns of the duplicity of Dumbledore, who uses muggleborns as breeding stock. What will he do to escape that fate? He makes his own! Admittedly, I kind of lost track in chapter 2, but I think it ended quite nicely.
Harry realizes there are no consequences to bad behavior and decides to try it out. Ironically, there are far-reaching consequences. His life takes a drastic turn when he decides against being a saviour and he sets out on his own. Still, Hermione was right; Harry Potter has a saving people thing! He opens his doors and finds himself a good life and wife.
What does one do when they realize they're a pawn? Harry is going to take any good opportunity to escape the playing board. It just so happens that the way he does it, ends the game! Harry is a human hybrid! His two separate DNA strings only viable because of magic, shunting it into a human Animagus form. When he finds out, stuff happens.
After finishing the war, Harry realizes he never was Harry Potter. Who is he really? Read this complete short-story and find out as he figures it out! He's a Metamorphmagus with gender Other, so that can vary. With his typical Luck, he saves a few people along the way, but not like usually. Along the way, he finds love and acceptance.
