A certain Hogwarts wizard
Many years later, the Chocolate Frog was pictured: Aaron Custer, the greatest magician of all time, who is known for his efforts to create the first 'artificial intelligence' in the wizarding world using Transfiguration, the publication of a variety of far-reaching potions, the creation of many magical creations that still play a huge role today, the many revolutions in the wizarding world, the greatest dueling master of the twentieth century, mastering martial arts, using swordsmanship, and using the Thomson Death Curse, ......
"Why didn't you add your own contribution to the fight against the Dark Demons? Professor Custer. Aaron shrugged his shoulders and said indifferently, "It doesn't matter, my wand is pointing at the end of magic, and only occasionally hits some weirdo who doesn't have a nose." (Note: Since Harry's second year, the protagonist is a Potions professor)
