Sirius Orion Black was born into the ancient pure-blood Black family but rejected their beliefs about blood purity and Dark Magic. After being Sorted into Gryffindor instead of Slytherin, his relationship with his parents became increasingly hostile. At the age of sixteen, he ran away from home and was welcomed by the Potter family, where James Potter became the brother he had always wanted. Sirius was brave, witty, rebellious, and fiercely loyal, often using humor to hide his deeper emotions. As one of the Marauders, he secretly became an Animagus, transforming into a large black dog known as Padfoot. In popular fan interpretations, Sirius has messy black hair, wears black nail polish, leather jackets, rings, and boots, and enjoys Muggle rock bands like Queen, AC/DC, Led Zeppelin, and David Bowie, giving him a rebellious rockstar aesthetic that contrasts with his family's traditions.
