Harry Potter's presumed dead God-father/doggy. One time best friend of James Potter and Remus Lupin, "killed" at the hands of one evil bitch of a cousin Bellatrix Lestrange. Also, hands off, as he is betrothed to the aforementioned Remus Lupin.
The Sexy Marauder
Sirius - "You can't be serious, I'm Sirius!"
James - "Sirius, seriously, that joke is really old."
Sirius - "Seriously?"
For the next two years, Sirius remained in hiding. He served as a confidant to his godson, Harry Potter, through letters and secret meetings. In Harry's fifth year, however, Sirius went to save Harry in a battle against Voldemort and some of his Death Eaters. Bellatrix Lestrange, a cousin of Sirius's as well as a Death Eater, sent a spell towards Sirius. As a result, he fell beyond a dark veil, where he is presumed to be dead.
"I trusted you," he stuttered.
The man laughed bitterly. "You were always dim-witted, Sirius."
