Sirius Black

Sirius Black III 3 November[1] 1959[16], also known as Padfoot or Snuffles (in his Animagus form), was an English pure-blood wizard, the older son of Orion and Walburga Black, the older brother of Regulus Black. Although he was the heir of the House of Black, Sirius disagreed with his family's belief in blood purity and defied tradition when he was Sorted into Gryffindor House instead of Slytherin at Hogwarts School of Witchcraft and Wizardry, which he attended from 1971 to 1978. As the rest of his family had been in Slytherin, he was the odd one out.
