Sirius Black III

Sirius Orion Black III (b. 3rd November 1959) is an English Pure-Blood wizard and the disgraced Heir of House Black, disowned for his pro-Muggle beliefs and running away from home at the age of sixteen to seek sanctuary with the Potters. The son of Orion and Walburga Black and older brother of Regulus II, Sirius has always been a rebel and non-conformist, being the first Gryffindor in an all-Slytherin family. Sirius is, along with James Potter, Remus Lupin and Peter Pettigrew part of the Marauders, four former Gryffindor classmates and best friends who created the Marauders Map to cause mischief and merriment. To help Remus during his monthly werewolf transformations, Sirius became an unregistered Animagus and transforms into a Grim-like dog. He is a member of the Order of the Phoenix, established to oppose the Death Eaters.
