Sancrin has a mustache which he shaved off as Brook's manager and black hair. As a longarm, he has double-jointed elbowed arms. While still a kidnapper, he wore an orange Chinese garb with the kanji 盗 (tō, to steal) on it. As Brook's manager he wore a yellow suit with a red shirt underneath, and a black bow tie. He also wore red sunglasses with blue lenses.
He is greedy and opportunistic, kidnapping humans in order to exhibit them, and then taking advantage of Brook's mercy to kidnap him for the same reasons. Sancrin shows that he did not believe in devils and occult, as he was not afraid of Brook of being a skeleton, despite not knowing he was a Devil Fruit user at the time. When Brook was planning to retire from the rock band industry to return to his crew, Sancrin was fully willing to betray him to the Marines to gain some last minute benefit (the bounty on Brook's head) and revenge, and even held him at gunpoint to prevent him from escaping, proving himself to be a very treacherous man.
