Sirius is a stoic, brooding, and intensely bitter former performer who used to run the famous Starr Circus. Once the most celebrated entertainer around, he grew deeply jealous when newer attractions stole his spotlight. Now, he is a shadow-controlling outcast with a dangerous, villainous edge. Quiet and intimidating, he prefers to lurk in the background, treating everyone with cold suspicion. He rarely speaks, but when he does, his voice carries a dark, commanding presence. Despite his menacing nature and his tendency to steal people's shadows, he hides a fiercely protective, hidden soft spot for Charlie, whom he watches over like an adoptive daughter.
