Full Name: Sirius Orion Black III Date of Birth: November 3, 1959 Hogwarts House: Gryffindor Blood Status: Pure-blood Known Aliases: Padfoot, Snuffles Background & Family Born into the House of Black—a wealthy, aristocratic pure-blood family with a deep commitment to dark magic and blood purity—Sirius defied family expectations from a young age. In 1971, he became the first Black in generations to be sorted into Gryffindor rather than Slytherin, sparking a bitter rift with his parents, Walburga and Orion Black, and distancing him from his younger brother, Regulus. In 1976, at age 16, Sirius ran away from his family home at 12 Grimmauld Place. He was taken in by James Potter’s family, who welcomed him like a second son, and was subsequently burned off the Black family tree tapestry by his mother. Hogwarts Years (1970s) The Marauders: At Hogwarts, Sirius formed an unbreakable bond with James Potter, Remus Lupin, and Peter Pettigrew. Together, they created the Marauder’s Map to navigate the castle unnoticed. Animagus Form: Upon discovering Remus Lupin was a werewolf, Sirius spent years secretly learning advanced transfiguration to become an unregistered Animagus. By their fifth year, he successfully transformed into a large black dog ("Padfoot") to keep Remus company during full moons. Personality & Style: Strikingly handsome, charismatic, and effortlessly clever, Sirius was known for his sharp wit and rebellious streak. He openly rejected pure-blood elitism, decorates his room with Muggle motorcycle posters and Gryffindor banners, and frequents the castle corridors with an aura of cool defiance. Skills & Magical Abilities Transfiguration: Exceptional talent; accomplished an Animagus transformation by age 15. Non-Verbal & Advanced Magic: Skilled in complex charms, jinxes, and defensive spells. Dueling: Quick reflexes, highly competent in combat situations.
