I had this idea a couple days ago, I thought it would be interesting to see if someone would write it...

Plot: It's been over 20 years since Harry has defeated Voldemort. After the war he traveled before he came back to take up the position of DADA teacher. After a few years of teaching something shocking is revealed to him. The daughter of Dudley Dursely has been accepted to Howarts.

He decides that it would be best if he goes to inform his "family." When he gets there he finds that the girl has been treated even worse than he was. As a child Vernon and Petunia were afraid to beat Harry for fear of Dumbledore appearing, but Dudley didn't have that fear. He believed just like his father he could beat the magic out of his daughter.

Instead of beating the magic out of her, the magic stayed and she turned into a cold and callous person with signs of mental imbalance. As Harry talks to her he can't help but compare her to the images of an 11 year old Tom Riddle. She shows all the signs that Riddle has shown at that age of becoming a sociopath; animal abuse, bullying other kids, controlling her magic to an extent to cause harm, hatred for those considered normal by her father, etc.

Seeing the possible danger of another Tom Riddle Harry takes her away from the Dursley family.

...End summary...

The fic would focus on things like Harry desperately trying to steer his Cousin away from the Dark. And it would focus on her expieriences at Hogwarts. She would no doubt expierience the bigotry of the magical world and see that it just doesn't happen in the muggle world.

It would be up to the author if she becomes a Dark Lord or Harry is able to prevent it. Personally I would like to see her become a Dark Lord(or would it be Mistress?)

I could imagine Harry's turmoil if he had to fight her to the death. Of course that wouldn't take place untl years after her graduation.

 

"You were my brother Anakin! I loved you!"

Sorry, couldn't resist it, but it sounds a lot like setting up for a sort of Mustafar type situation, with two folk who have known each other for years and have been close having to fight to the death.

Could be interesting...but I'm not convinced it would make a decent fic. I've read a few which involve Harry taking Dudley's child away from him, and they never really manage to spark my interest.

 

Yeah, I have read a few of those fics, but most of the time the Dursley child is still a sweet and innocent child after years of abuse and then eventually falls away from the plot as Harry deals with more pressing issues. It would be different if she turns out to be a basket case that loves causing pain.

 

ive never read one that has really gone anywhere

likewise I think it would be interesated that went for more than a few chapters
