Pesche and Dondochakka resolve to follow her but forget which direction she ran off in.
Soon after, when the group splits up in Las Noches, Nel runs off to follow Ichigo. Pesche's guess of how strong the group is, with Uryū at the bottom. Pesche and his group settle down after Runuganga is dispatched by Rukia Kuchiki, and introduce themselves to her and Renji Abarai. However, as Ichigo tells them that he isn't going to harm them, Runuganga appears and attacks the group. However, when she learns that Ichigo is a Shinigami, she panics with Pesche and Dondochakka, believing that he is going to kill them. Nel and her group apologize for causing a misunderstanding, explaining that they were playing a game of "eternal tag." Pesche explains that he is Nel's "older brother." Afterwards, Pesche rides across the desert on Bawabawa's back with the rest of the group, as Nel talks about the different types of Arrancar that exist in Hueco Mundo. However, Nel suddenly interrupts, confusing Ichigo's group.
Ichigo Kurosaki, Uryū Ishida, and Yasutora Sado attack the trio, believing that they are trying to harm Nel. Pesche initially appears alongside Dondochakka and Bawabawa, chasing Nel across the desert of Hueco Mundo. He and Dondochakka spent the following time traveling around Hueco Mundo, keeping Nel amused with games like Eternal Tag, while still training to better protect her. They feared that not doing so would cause her memories to come back, which neither of them wanted since Nelliel strongly disliked fighting, and in her child form, she would no longer have to fight. They hid their true identities from Nel, going as far as to modify their appearances. Nelliel reverted to a child with few of her powers and none of her memories, so Pesche and Dondochakka decided to dedicate their lives to protect her. After breaking her mask with a sneak attack, Nnoitra and Szayelaporro threw all three of them off the dome of Las Noches. Both he and Dondochakka had their masks forcibly removed by Nnoitra Gilga and Szayelaporro Granz and were used as bait to lure Nelliel into a trap. Pesche was the 41st Arrancar in Aizen's army, in which he and Dondochakka served as Nelliel Tu Odelschwanck's Fracción. He is also very loyal to Nel, casting aside his goofy nature and taking up a leadership role whenever she is in need. However, despite this, he is capable of being serious, especially if his "brothers" are in danger. Pesche is perverted, losing his focus when he realizes that he could see Cirucci Sanderwicci’s underwear from afar. He temporarily becomes jealous of Dondochakka Birstanne when he finds the latter buried in an 'interesting' battle pose. He also enjoys having attention and is unhappy when no one notices him. He is also very forgetful, as he calls Uryū Ishida as "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. At the same time, however, he seems to be dimwitted, not even realizing that Ichigo is a Shinigami until Nel points it out. Initially, he is deathly afraid of Shinigami, panicking when he first learns that Ichigo is one of them. PersonalityĪt first glance, Pesche is rather cowardly, usually hiding from enemies rather than facing them.
He had pale white skin with shoulder-length hair. When he was a Fracción, Pesche wore a customized Arrancar uniform with puffy shoulders. Pesche walks around barefoot and has only three toes on each foot. His Hollow hole is positioned near his stomach, directly beneath the edge of his vest. He also wears a loincloth around his waist, which is a lighter shade of purple than the rest of his body. 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. Pesche has blond hair, some of which sticks out from under the back of his mask. However, his right eye is concealed by a purple eye patch, which is attached to his brow. His large left eye, yellow in color, is visible through an eyehole on the front of his mask. 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.
