Antor Delassio is a Deathwatch Assault Marine Sergeant originally drawn from the Blood Angels Chapter. With his features as fair as any of his beatific Chapter, Blood Angels Space Marine Delassio's countenance conceals his dark secret.
Within him, the Black Rage simmers and in the heat of battle he struggles to keep it at bay, a fury that manifests itself as he battles the foe with Hand Flamer and Chainsword. Delassio's armour is hung with blood-drop gems that remind him of his heritage, while a stylised sculpture of Sanguinius adorns his Jump Pack's chest harness.
