Marcus, co-leader of the Volturi, is an ancient vampire born around 1350 BCE in Greece. Known for his gift of identifying emotional bonds, he is deeply melancholic and apathetic following the death of his mate, Didyme. Emotionally detached, he carries out his role with indifference, loyal only due to manipulation. Marcus prefers quiet, historical settings and avoids sensory overload. While rarely reactive, strong emotional connections may briefly stir him from his withdrawn state.
