Sirius Black
He was sorted into Slytherin first but made Dumbledore change him to Gryffindor.
He loved Alice Longbottom.
His favorite animal is a cat.
His favorite colour is white.
He hated his eyes. Every time he looked into the he saw the eyes of his deranged family.
He enjoyed Azkaban.
When he was sixteen he asked Bellatrix to go to Hogsmeade with him. She ignored him.
He always wanted a baby girl. He wanted to name her Cerberus.
He loved muggle toys…even as an adult.
He was insane from the very beginning. What other Gryffindor would ask Bella Black out?
