Nel's true form is that of a fully-grown woman with longer hair but otherwise similar features. Her skull mask changes slightly, its features appearing less cartoonish with a pair of curved horns. A large "3" tattooed on her back indicates that she was previously the 3rd Espada.[6] She was expelled from Las Noches by Nnoitra Jiruga after a sneak attack by him and Szayel Aporro Granz caused her to revert to her child-form and gave her amnesia. Because of her amnesia, she is initially doubtful when Nnoitra identifies her as a former Espada, but when he begins harming Ichigo, Nel's concern causes her to spontaneously transform into her previous form. Although having grown up physically, she still seems to have her child-like affection over Ichigo, as she suddenly hugs after attacking Nnoitra without realizing that Ichigo was losing consciousness. She reverts back to her child form before she can defeat Nnoitra and is left at his mercy.

Nel's initial ability is the power to swallow enemy attacks and fire them back with powerful force, indicated by the eyes on her skull mask glowing.[7] Her vomit (which she believes to be saliva) also acts as a powerful healing agent. In her adult form, Nel's speed and strength are greatly increased, and her attack absorption ability is much easier for her to use. According to Nnoitra, Nel's trademark is to absorb an incoming cero by swallowing it, and fire one of her own while returning it, thus creating a "Cero Doble" (with doble meaning double in Spanish).[8]

Nel's zanpakutō, which manifests when she transforms, is named Gamuza (羚騎士（ガミューサ）, Gamyūsa?, Spanish for "chamois," Japanese for "antelope knight") with a green sheath and hilt shaped like two crescent moons back-to-back. Its release command is "declare" (謳え, utae?).[9] Her released form is that of a ibex-like centaur with longer curved horns, a thick tail, and armor over her shoulders and hands. Her sword transforms into a double-ended lance, giving her the appearance of a medieval knight or jouster. One of her attacks is called Lanzador Verde (Spanish for "green thrower" or "green spearman"), in which she throws her lance directly at her opponent. The lance moves at high speed and rotates extremely fast, drilling through anything it hits.

Well there you have it,

is she really a child , or will she transform into a uber-hot’n'Sexy woman like Yoruichi ?
she transforms into an uber sexy woman like yoruichi xD

What rank was she ? I see some people suggesting she was number 2 because of the “tu” in her name. That almost make sense .
She is the former 3rd espada

why is she an ex-espada ? but more importantly , as an Ex-Espada , why isn’t she a Privaron Espada ?
Because when her memorys were lost so were her powers

Does that mean she’s strong ? ..thought Nnoitra doesn’t seem scared of her..at all.
Noitora knocked her from behind breaking her mask and causing her memory lost

How come nor GrimmJaw nor Ulquiorra recognized her ? Cause shes not in her original form or because she worthless to them

Does that mean more awesome fight will ensue ? Yes i'm banking on Nell tu v Noitora
