Esdeath is a sadist and manipulative, psycho with no morals. She is a social Darwinist, who lacks empathy for people whom she deemed weak since she lived by her father's philosophy ("The strong survive and the weak die"). She enjoyed putting her enemies through great pain. She is the strongest general of the empire, and killed many in its name. She is a battle maniac and has no hesitation to kill. She has very strong ice powers and rapier skill. Most of times she looks calm.
