Dumbledore is the greatest of all time (G.O.A.T.).
He played a major role in the Global Wizarding War, he served as the headmaster at Hogwarts for over 30 years, he dueled against Voldemort as an equal, and he managed to protect Harry Potter until he was old enough to finally put an end to Voldemort's evil schemes.It's not really up for debate.O.A.
