HP-verse:

Somewhere on the boorus is an image of Draco Malfoy eating a WWW product that turns him female.

Now, for the What If...

S/he sneaks a nugget of the feminiser into Harry Potter's food. As Harry eats it, he turns female but due to the magic in the scar combined with the magic in the nugget, Voldemort and his marked subordinates turn female also, for as long as Harry does.
