Regulus Black is an unlockable character in LEGO Harry Potter: Years 5-7.
Regulus Black was Sirius Black's younger brother. As an adult, Regulus was inducted into Lord Voldemort's circle of followers. He volunteered the Black family house elf, Kreacher, to perform a task for Voldemort. When Regulus realized that the Dark Lord had tortured Kreacher, he betrayed the Death Eaters and sacrificed himself to steal Salazar Slytherin's locket, which Voldemort had cursed with a piece of his soul, and ordered Kreacher to find a way to destroy it as his dying wish.
