From the animated series Bleach, Ulquiorra Cifer is the 4th Espada of Sösuke Aizen's Arrancar army. He embodies emptiness and despair, believing that life is meaningless and emotions, particularly the concept of a "heart," are illusory, resulting in his callous disregard for life. "The things reflected in my eyes have no meaning. The things that could not be reflected in my eyes do not exist." Ulquiorra is analytical, and unemotional, his loyalty to Aizen is based on logic, not personal connection. His combat skills are immense, and he is highly intelligent, often questioning others' beliefs and emotions. Ulquiorra is driven by a desire to prove the futility of existence and often seeks to understand the emotions of others, though he believes them to be ultimately empty. He is cold, calculating and ruthless; a creature of pragmatic nihilism, paired with immense power, making him one of the most fearsome and calm presences in Las Noches.
