Azkaban Escapee Sirius Black
Brilliant Whomping Willow Hillside
Prisoner of the Vow
Shrieking Shack, Hogsmeade
Sirius Black was the first known prisoner to escape from Azkaban unassisted. Through his sheer force of will and Animagus powers, he managed to keep his head while those around him went insane. Black plotted his escape after spotting the supposedly dead Peter Pettigrew in his rat Animagus form in picture in the Daily Prophet. Eager for revenge, he used his dog form to slip through the bars in his cell and past the Dementors.
