When you’re ten years old, a Hogwarts professor comes to teach you how to cast a Patronus. People were worried at first -- they said ten was too young. You can’t even go to Hogwarts. But the grass around your house could be dangerous, and besides, the consequences for mistakes aren’t that bad.
Your natural Patronus is your starting Pokèmon. A lot of people have Rattata Patroni, but not all. Those with more uncommon Patroni get special attention from the Professors. Some of them are given a special spellbook they call a Pokèdex and told to find as many different Patroni as they can.
Patroni want nothing more than to protect their casters from harm. To do that, they practice against other Patroni. This is called a battle. The winning Patronus becomes stronger and better able to protect its caster.
Besides the Patroni of known casters, there are others that wander Great Britain. No one knows quite where they come from. Some say they are the Patroni of people killed in the Battle of Hogwarts. Others say they formed spontaneously from happy memories. Regardless, they roam the lands. Some casters tame them with spells -- a burst of red light, and then they will serve you loyally.
A few Patroni of immense power roam Great Britain as well. They are said to have belonged to tremendously powerful wizards. Over time, they come to be known as “legendary.”
Godric Gryffindor’s is known as Articuno. Only the bravest dare to venture to its frozen home. Ho-oh, guardian of the skies, is mastered by Helga Hufflepuff, protecting Hogwarts with the help of a Patronus. Salazar Slytherin’s is referred to as Rayquaza. It knows how to manipulate others to get its way. Rowena Ravenclaw’s is named Giratina. Its alternate dimension fascinated her, and even today the brightest students of her house are encouraged to seek out and learn from Giratina. Merlin, as a valuer of ideals, cast a Patronus known as Zekrom.
There were others, of course. For centuries, there had been thirty others. But then, shortly after the Battle of Hogwarts, a new legendary Pokèmon appeared out of the remains of Lord Voldemort.
Its name was Yveltal.
Pokemon, but with patronuses
I… have no idea how this would work I’m sorry. Anyone want to reblog this with their thoughts?
