A God-Tier sign-in System activates! From the start, he gets a Concept Editor and becomes a Walker of Time and Space! While everyone else is still playing with wands, Leon is already editing reality!

The Sorting Hat freaks out on the spot: "You are a mistake!"

Dumbledore: "You can't!" Leon: "Father, your phoenix is mine now."

Snape: "Monster!" Leon: "Quiet, my potions assistant."

Voldemort: "Stop!" Leon: "Quiet, my soul research material."

McGonagall and Flitwick break down together: "Please, stop coming to class!"
