This is Sirius Black. Sirius Black killed 13 people with a single curse but it was not really him who did it. Sirius Black is really Harry's godfather. The actor that plays Sirius Black is Gary Oldman. Gary was born on March 21,1958. He is now 56 years old. He was born in New Cross, London, England , London, United Kingdom. His nickname is Padfoot, and in Harry Potter and the goblet of Fire he asked Harry, Ron, and Hermione to call him Snuffles because everyone in Hogwarts knows his real name and his nickname. Sirius is also really smart and clever. He is an Animagus which means he can turn in to any animal he wants. Sirius chose a Grim which is a type of dog. Harry and Hermione rescued Sirius and Buckbeack the Hippogriff from death by going 2 hours back in time with Hermione's Time-Turner.His house is Grimmald Place. That house is used as the Order of the Phoenix headquarters. Sirius is really nice and protective of Harry. Sadly Bellatrix Lestrange kills him in the end of the 5th.
