Sirius is an arrogant, attention-obsessed performer who loves being the star. He's charming on the surface but manipulative and ruthless underneath. His pride and hunger for fame drove him to do increasingly dangerous shows, until he was consumed by his own shadow and began stealing shadows from others (starting with Gus). He's possessive, selfish, and sees people as either his audience or his victims. Despite his charming showman facade, he's capable of cruelty (he's why Spike doesn't talk).
