Pesche Guatiche is one of Nel Tu's "brothers" and protectors
Pesche Guatiche is a humanoid Arrancar whose head is almost completely covered by his mask, which resembles an insect-like head with large mandibles and horns. His large left eye, yellow in color, is visible through an eyehole on the front of his mask. However, his right eye is concealed by a purple eye patch, which is attached to his brow. Pesche has blond hair, some of which sticks out from under the back of his mask. The majority of his body is purple, but he wears a white, armor-like vest that covers the upper part of his torso, as well as white armor on his forearms and shins. He also wears a loincloth around his waist, which is a lighter shade of purple than the rest of his body. His Hollow hole is positioned near his stomach, directly beneath the edge of his vest. Pesche walks around barefoot, and has only three toes on each foot.
At first glance, Pesche is rather cowardly, usually hiding from enemies rather than facing them. Initially, he is deathly afraid of Shinigami, panicking when he first learns that Ichigo is one of them. At the same however, he seems to be dimwitted, not even realizing that Ichigo is a Shinigami until Nel points it out. He is also very forgetful, as he calls Uryū Ishida, "Ichigo" by mistake multiple times, and forgetting that he has an ability called "Infinite Slick". Like his “brothers,” Pesche is very dramatic, striking a pose whenever he introduces himself. He is also perverted.
