Neliel Tu Oderschvank
Neliel Tu Oderschvank, otherwise known as Nel Tu[5] (ネル・トゥ, Neru Tu?), is a good-natured, childlike arrancar when first introduced. The remains of her hollow mask make up a cartoonish skull on the top of her head. 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. Ichigo 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

Grimmjow Jeagerjaques
Grimmjow has light blue hair and eyes, which have blue/green lines below them similar to the eye markings on the Panthera genus of cats as well as the red marks on Ikkaku Madarame's eyes. Grimmjow's attire consists of a white hakama and a black sash; his white jacket is ragged with an upturned collar. The inner lining is black, the sleeves are rolled up, and Grimmjow wears it open, leaving his chest revealed. The remains of his hollow mask consist of the right jawbone, and his hollow hole has moved to his abdomen.

Nnoitra
Nnoitra is the fifth Espada, signified by the "5" tattoo on his tongue, making him the fifth strongest arrancar in Aizen's army. He is an extremely tall and lanky arrancar, dwarfing Yasutora Sado by at least a foot (even when leaning over. He has long, black hair and almost always wears a huge smile on his face which reveals his upper teeth. He wears an eyepatch, three bracelets on each wrist, and his arrancar uniform includes an overblown, spoon-like hood. The remains of his hollow mask and hole are not visible.
