Pesche Guatiche

is one of Nel Tu's "brothers" and protectors.

Appearance
Pesche Guatiche 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. While in the Forest of Menos, Pesche lifts up the eyepatch to show the Adjuchas-class Menos that, like Nel, he too was "broken" (i.e., an Arrancar), though he does this with his back to the camera. His Hollow hole is slightly lower than normal, positioned near his stomach instead of his chest. Pesche has blonde hair, visible under his mask. His appearance is first compared to that of an ant (termite in the English Dub), but he prefers to be compared to a stag beetle.

History
He and Dondochakka were once Nelliel Tu Odelschwanck's Fracción, but they had their masks forcibly removed by Nnoitra Jiruga and Szayel Aporro Granz. The pair used Pesche and Dondochakka as bait to lure Neliel into a trap, and when Nnoitra had broken her mask in a sneak attack, he threw all three of them off of the dome of Las Noches. Neliel reverted to a child with little of her powers and none of her memories, so the two of them decided to dedicate their lives to protecting the newly weak Nel. According to Pesche, they hid their true identities from Nel, even going as far as modifying their appearances. They feared that not doing so would cause her memories to come back, which neither of them wanted since Neliel strongly disliked fighting; in her child form, 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 to better protect her, likely in secrecy.

Hueco Mundo
Pesche initially appears alongside Dondochakka and Bawabawa, chasing Nel across the desert of Hueco Mundo. Ichigo Kurosaki, Uryū Ishida and Yasutora Sado attack the trio, believing that they are trying to harm Nel. However, Nel suddenly interrupts, confusing Ichigo's group. Nel and her group apologize for causing a misunderstanding, explaining that they were playing a game of Eternal Tag. As they explain their relationship to Nel, Pesche explains that he is her "older brother". Afterwards, Pesche rides across the desert on Bawabawa's back with the rest of the group, as Nel explains the different types of Arrancar. However, when she learns that Ichigo is a Shinigami, she panics with Pesche and Dondochakka, believing that he is going to kill them. However, as Ichigo tells them that he isn't going to harm them, Lunuganga appears and attacks the group. Pesche and his group settle down after Lunuganga is dispatched by Rukia Kuchiki, introducing themselves to her and Renji Abarai. When the group splits up in Las Noches, Nel runs off to follow Ichigo. Pesche and Dondochakka resolve to follow her, but forget which direction she ran off to. Pesche accidentally follows the path that Uryū took, stumbling across the latter's battle against Cirucci Sanderwicci. This initially upsets Pesche, as he believes that Uryū is the weakest member of the group, while thinking that Chad is the strongest. Pesche assists Uryū with his Infinite Slick ability, annoying Cirucci to the point of releasing her Zanpakutō. After Cirucci's defeat, Pesche and Uryū run into Renji during his fight against Szayel Aporro Granz. As Uryū joins the battle, Pesche remains on the sidelines, hiding from Szayel's Fracción. He realizes that Dondochakka, who had ended up following Renji instead of him, is nearby, trapped in a pile of rubble. Pesche attempts to extract him from the rubble without alerting the Fracción, but Dondochakka bursts out shouting, grabbing their attention. However, as the Fracción prepare to attack them, a sudden attack by Renji inadvertently knocks them down. After Szayel retreats from battle to change out of his ruined clothing, Pesche and the others attempt to escape from the chamber, only to find themselves back where they had started, due to Szayel's manipulations. Only when he and Dondochakka have realized Nel has returned to her true form do they show their 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 movements, reiatsu, and experience enough while he was fighting Uryū and Renji, and that doing so had allowed him to predict and exploit a weakness in the technique. In the anime, this weakness is spelled out as a small fissure where the two ceros are not perfectly mixed, which Szayel touches to break the orb of synchronized cero into two, which pass by him by harmlessly. Nevertheless, the duo's brief intervention bought enough time for them to be saved by the cavalry from Soul Society: in their case Mayuri Kurotsuchi. After Szayel's death, Mayuri's artificial daughter, Nemu, almost kills Pesche and Dondochakka while digging through the remains of Szayel's lab. Mayuri orders her to get rid of them and she sends them flying away. Their current whereabouts after this are unknown.

Powers & Abilities

 * in which he sprays his saliva at an object, severely reducing its friction. Though seemingly useless, he is able to render Cirucci Sanderwicci'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.

Cero: Pesche, being an Arrancar and a former Fracción, has the ability to fire a purple-colored Cero from his Zanpakutō Última. The only time he is seen using it is when he creates the Cero Sincrético with Dondochakka Bilstin's own.

Cero Sincrético (融合虚閃, セロ・シンクレティコ, sero shinkuretiko; Japanese for "united hollow flash", Spanish for "synchronized zero"): A synchronized Cero attack with Dondochakka. They both fire Ceros, which combine to form one "wonderfully powerful" (as described by Szayel Aporro Granz in the original Japanese version) Cero, that produces a big explosion upon impact.

Zanpakutō

 * In addition to his powers, he carries a sword of glowing light, made entirely out of spirit particles, which he compares to one of Uryū's Seele Schneiders (Pesche refers to them as "thingies"). Humorously drawing it from his loincloth using its vaguely phallic hilt, Pesche shocked Szayel enough to land a cut across his arm. In the anime, his claim of having a "thing" superior in length and usefulness of to Uryū's causes Dondochakka Bilstin to pop up warning anyone watching not "imitate him". Its guard has two partial circles on each end, somewhat resembling crescent moons.
