Nelliel Tu Odelschwanck

Nelliel Tu Odelschwanck (also known as Nel Tu in her child form) is a prominent character in Bleach. She is a female Arrancar and the former Tres (3rd) Espada in Sōsuke Aizen's army.

She first appears as a small, childlike, good-natured, and playful Arrancar living in the deserts of Hueco Mundo with her loyal companions (former Fracción) Pesche, Dondochakka, and their pet Bawabawa. In this form, she has hazel eyes, short green hair, a cartoonish skull-like Hollow mask remnant on her head, and a very innocent, somewhat quirky personality (despite occasionally using surprisingly mature or odd vocabulary).

Her true adult form is that of a tall, mature, curvaceous woman with long green hair, a scar across her face, and a much more composed, intelligent, logical, and warrior-like demeanor. She reverted to her child state after a betrayal by Nnoitra Gilga damaged her Hollow mask, causing her powers and memories to become unstable.

Nelliel is known for her compassion (unusual among most Arrancar/Espada), strong sense of honor, and protective nature toward those she cares about. Her Resurrección is Gamuza, which takes a centaur-like form with powerful lance-based combat abilities.
