Chrollo is a young man with black hair and grey eyes. Two of his distinguishing features are the cross-shaped tattoo on his forehead and a pair of orb-shaped earrings. Chrollo is calm, intelligent, and charismatic, as he seems to be a born leader and able to hold the Phantom Troupe together despite the volatile personalities of its members. While he is a very capable strategist, Chrollo is also very confident in his own fighting abilities as well as in those of the other members of the Spider.
