Pesche Guatiche

Pesche is a seemingly harmless, humanoid Arrancar whose mask resembles an insectoid head with a large pair of mandibles. He wears an eyepatch and a loincloth. His Hollow hole is slightly lower than normal, positioned near his stomach instead of his chest. He and Dondochakka were once Nel Tu's Fracción, but had their masks forcibly removed by Nnoitra Jiruga and Szayel Aporro Granz, and were left for dead with Nel. After realizing that their master had reverted to a defenseless child, he and Dondochakka pledged to protect her. According to Pesche, they hid their true identities from Nel because they feared not doing so might cause her memories to come back, which neither of them wanted, because Neliel strongly disliked fighting, and in her child form she would no longer have to fight. He and Dondochakka spent the following time traveling around Hueco Mundo, keeping Nel amused with games like eternal tag, while still training (probably without her knowledge) to better protect her.

Pesche accidentally accompanies Uryū Ishida into Las Noches, having thought he had followed Ichigo (whom Nel had been chasing). This initially upsets Pesche as he believes Uryū to be the weakest member of the group due to his appearance, while thinking that Chad is the strongest. The two find Renji and Dondochakka, who had similarly run into each other, and all four are soon forced into a fight with Szayel Aporro Granz in his released form. Only when he and Dondochakka have realized Nel has returned to her true form do they show they true power. However, their most powerful attack, Cero Sincretico does not work on Szayel-Aporro, because, he tells them, they didn't use it right when the battle started: he had recognized them all along, and had analyzed their reaitsu enough while he was fighting Uryu and Renji that he could nullify their attack. Pesche, Dondochakka, Uryu, and Renji are then saved by the cavalry from Soul Society: in their case Mayuri Kurotsuchi.

Pesche possesses an ability he calls, in which he sprays his saliva at an object, severely reducing its friction. Though seemingly useless, he is able to render Cirucci Thunderwitch's weapon ineffective by coating it in his liquid, and it can be used similarly to make opponents lose their footing or grip on things. The liquid is limited in supply, contrary to its name. Pesche states that he named it as such because "Finite Slick" didn't sound nearly as cool. He can also perform a synchronized cero attack with Dondo. In addition to his powers, he carries an energy sword he calls which he compares to one of Uryū's Seele Schneiders, humorously drawing it from his loincloth using its vaguely phallic hilt.
