Ok guys. I don't know about you but I really like the stories where Voldemort screws around with Harry's mind and turns him to the side of darkness. I don't mean that he kidnaps harry as a baby, or gives him a potion that turns him right away, I am talking dark mind fuck kind of stuff. There isn't enough of that if you ask me, and it should have its own category.
Here is a prompt, that anyone is welcome to take. I would do it myself but I don't have enough bata readers.
Voldemort captures Harry (after his resurrection, or at the battle in the ministry of magic.) with the intention of turning harry into his most loyal follower.
The story can take as long as you want it to but there are a few things that I would like to see in the end.
First by the end Harry will no longer think of himself as Harry Potter, or even really think of himself as really being human anymore. He will see himself as Voldemort's pet "the little serpent."
If Harry acutely still a human or had been turned into a snake is up to you, but I want Voldemort to use Harry to fight for him in some way during battle.
If you chose to keep Harry as a Human I would like it if he can only understand Parseltoung.
An alternate Story could be Voldemort taking control of Hermione. He could do this by using her thirst for knowledge against her. I am thinking that he traps her mind in a vast library that represents all of his knowledge. With her mind trapped he can control her body without resistance.
