Nelliel Tu Odelschwanck, formerly the 3rd Espada, is an Arrancar who typically appears as a small child with green hair and a fragment of a hollow mask. She speaks with a lisp and uses bizarre phrases, often acting childish and affectionate, especially towards Ichigo Kurosaki. In her true form, she is a tall, curvaceous adult with sharp features and horns. Despite initially fearing Shinigami, she proved loyal and brave, fighting alongside her friends.
