A mysterious nobleman living in luxury, Le Comte de Monte-Cristo (モンテ・クリスト伯爵, Monte Kurisuto Hakushaku?) approaches and befriends Albert in Luna as the first step in his plan of revenge against the people who once betrayed him. The Count's previous identity was Edmond Dantès, a sailor who worked for the Morrel family's shipping company. Edmond was imprisoned in the Château d'If on false charges, and there it was that he met Gankutsuou (known as The Ruler of the Cave in Animax's English adaptation). In exchange for the strength and means to gain revenge, he allowed the cold-blooded demon to possess him. Because of Gankutsuou, he is afflicted with an odd condition which causes his body to become increasingly crystalline, revealing his bones and internal organs.

In the Japanese series, he is voiced by Jōji Nakata but he is voiced by Jamieson Price in the English version.
