Harry Potter: What If Harry Was The Villain? - 7 Ways It Would Have Changed
4. He Would Use Parseltongue To His Advantage
924967In a world where magic is the be-all and end-all and random crazy people can speak to snakes, you would think that a plague of snakes would befall the magic world and pretty much everyone would die, but because it's Warner Bros. and not HBO, this is not the case.
If Harry wanted to take over the magical world, he could use Parseltongue to his advantage and control the snakes kind of how The Rat King in Adventure Time or the one in Teenage Muntant Ninja Turtles control rats.
Of course snakes would be a lot more frightening for both muggle and magical being and I'm pretty sure he could have overthrown the ministry by using this technique if he had any interest to.
Why Voldemort never used this technique to reign, we will never know.
