at 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 Neliel, 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 Neliel has proven during her last few minutes as a full-fledged Espada, that it is acceptable when it involves vengeance. Unlike many of the Arrancar, Neliel is somewhat pacifistic, and according to her Fracción, has despised engaging in combat even when she was still among (one of the highest) Espada ranks, 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. Excluding Stark, Grimmjow, Halibel, and Ulquiorra, Neliel seems to be the most honorable member of the Espada; she will refuse to finish off weaker or incapacitated opponents, and will stop fighting them once they've been disabled or incapacitated. Despite this, she's rather merciless toward her opponents, and won't hesitate to kill them once it's been made clear that they'll lose. As witnessed during her numerous fights with Nnoitra, Neliel's shown to be relatively calm and silent when fighting, only speaking when spoken to, a rather uncommon trait among most Arrancar.
Neliel'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, which is likely why she decided to join Aizen's army.
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).
