Bio:
Born into the House of Black, Sirius had always been expected to be a perfect little pure-blood wiard and marry a little pure-blood witch. But, on the train to Hogwarts, Sirius met up with James Potter and managed to get into a fight. After the fight, though, the boys became best friends, especially after Sirius ended up in Gryffindor, rather than Slytherin. His family never forgave him for this.
The boys met up with Remus Lupin and then Peter Pettigrew, becoming close friends. In second year, the found out Remus' secret, and began to learn how to be aniamgi, finally managing in their fifth year. The boys were all finally able to transform into animals and follow Remus during full moons. By third year, they had already begun to call themselves 'the Marauders' for the many pranks Sirius, Peter and James pulled, sometimes accompanied, to their surprise, by Remus. The boys also began work on a map they called the 'Marauders' Map' so they would be able to leave a bit of help for the future generations. Sirius, though, was always the Marauder who got the most attention of the girls, having the Black 'Good looks'. He ignored, them of course, enjoying tricks and things much more. He had always been thankful for the secret passaged around Christmas time, though, with girls waiting for him by mistletoe in every other corridor.
Summer time was Sirius' least favorite time. He recieved beatings from his mother for not being a perfect little pureblood, and usually ended up spending the time at James' home instead. He ended up trusting his friends much more than his family, which wasn't necesarrily a bad thing. With Voldemort coming into power, his home was all for it, while he did his best to ignore it. He begame steadily more jealous and angry with his brother, Regulus, and always seemed to get him into trouble at Hogwarts. Sirius' mother, of course, sent many letters and Howlers whenever he did such a thing, but he rarely read them. James usually did, scowled, and threw them into the fire, instead, informing Sirius only of things he should ahve been informed of.
Fun Facts: Sirius is most protective of Remus, though James is his best friends.
Sirius had an interest in Muggle weapontry he himself can't explain too well.
Unlike James, Sirius tries to avoid his fangirls the very best he can, though very rarely, he becomes intruiged with one or two.
Though sometimes he comes off as selfish, Sirius can see more in a girl than looks alone, and even had somewhat of a 'cootie' complex for a few years.
