Nel Tu (ネル・トゥ,Neru Tu, ), originally incorrectly romanized as Nel Tu, is the former Tres (three) Espada. She is also known as Nelliel Tu Odelschwanck (ネリエル・トゥ・オーデルシュヴァンク, Nerieru Tu Ōderushuvanku), and she is a small, good-natured, childlike Arrancar. She lives in the desert of Hueco Mundo with her adoptive brothers and former Fraccion, Dondochakka Birstanne and Pesche Guatiche, and their pet, Bawabawa.

Nel is a female Arrancar that has hazel eyes and blue-green hair. She has a large scar coming down from her forehead to her nose, larger than average incisors, and a crimson line that stretches horizontally across her face right below her eyes.The remains of her Hollow mask make up a cartoonish skull on the top of her head. A crack runs along the left side of the mask and four of the teeth on it are broken off.

The location of her Hollow hole is currently unknown. Her clothing consists of a simple green gown, which, in her original form, tears to become a top and skirt.  Her previous form is that of a full-figured woman with long waving hair but otherwise similar features. Her skull mask changes slightly, its features appearing sharper and less cartoonish with a pair of curved horns. A large "3" is tattooed on her back, indicating that she was the former 3rd Espada.

Nel's appearance is in stark contrast to her vocabulary, which contains a number of bizarre phrases and words one wouldn't expect such a small child to know, such as calling her uvula a "throat penis" and referring to herself as a masochist. Ichigo Kurosaki assumes her Hollow companions are responsible for this. Nel and her companions also represent oddities among Hollows, though most Hollows are evil, Nel actually fears Shinigami, assuming they are in fact the evil ones. In spite of this, she develops an attachment to Ichigo and follows him into Las Noches. During their super sentai intro she prefers the name "Thieves: Nel-Don-Pe."

She also seems to speak with a lisp in her child form, frequently pronouncing "S"s as "T"s.As Nel Tu, she is much more mature, composed, logical, sophisticated, and intelligent than her child form. She is also relatively level-headed in terms of how to fight, stating that if one's excuse for a battle is to fight out of hatred, prejudice, or simple competition, as Nnoitra does, then it is merely instinctual and animalistic, and that it makes the challenger look "childish," "unworthy," and "not much of a warrior". Though Nel has proven during her last few minutes as a full-fledged Espada that it is 'acceptable' when it involves vengeance, she does not view even that as a reason to fight.

Unlike many of the Arrancar, Nel Tu is somewhat pacifistic, and according to her Fraccion, has despised engaging in combat even when she was still among the upper ranks of the Espada, unless it involves self-defense and protecting those dear to her heart. It is for this reason that Pesche and Dondochakka decided to simply be content with her child form and banished themselves from Las Noches.


She refuses to finish off weaker or injured opponents, and will stop fighting them once they've been disabled or incapacitated, a trait shared with Kenpachi Zaraki. As witnessed during her numerous fights with Nnoitra, Nel Tu's shown to be relatively calm and silent when fighting, preferring to speak only when spoken to, a rather uncommon trait among most Arrancar. She is even shown to enjoy reading, usually seen reading a book after her mission or after waiting for Nnoitra to wake up after their recent battle. 

Nel Tu's also shown to be a loyal, respectful, and trustworthy warrior, who will diligently follow the orders of her commander, provided said commander has proven his worth. She's also knowledgeable, analytical, easygoing, fairly compassionate (usually towards her friends), humorous in her own right, and exhibits a cheerful, energetic demeanor when off-duty. Although having grown up physically, she somehow retains her child-like affection over Ichigo, best-shown when she unexpectedly bear-hugged him after attacking Nnoitra without realizing that Ichigo was losing consciousness (although the anime's flashback of Nel's accident suggested that she was always somewhat childish outside of combat).
