Who He Is: Albus Dumbledore was the headmaster of Hogwarts and founder of the Order of the Phoenix. He was known as one of the most powerful wizards in the wizarding world.

What He Does: A wizard of legendary power, he was one of the few people whom Voldemort actually feared. He was the master of the Elder Wand for decades and instrumental in Voldemort's defeat, as well as Harry's journey.

His Strongest Moment: Dumbledore willingly gave his life for the fight against the Dark Lord.

His Weakest Moment: He was forced to drink the Emerald Potion - otherwise known as the potion of despair - in order to give Harry access to one of Voldemort's Horcruxes. The effects of the potion came in three stage: pain, reliving his worst memories, and intense thirst.
