Pesche Guatiche

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

Appearance
Pesche Guatiche is a humanoid Arrancar, whose mask resembles an insect-like head with a large pair of mandibles. He wears a purple eye patch that hangs over his right eye, attached to the brow. While in the Forest of Menos, Pesche lifts up this eye patch to show the Adjuchas-class Menos that, like Nel, he too was "broken" (i.e. an Arrancar), though he does this with his back turned. Pesche has blond hair, which sticks out from under the back of his mask. His Hollow hole is positioned near his stomach. His appearance is first compared to that of an ant by Cirucci Sanderwicci, but he prefers to be compared to a stag beetle.

History
Pesche served as the 41st Arrancar in Aizen's army and, along with Dondochakka, he was Nelliel Tu Odelschwanck's Fracción. Both he and Dondochakke 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 few of her powers and none of her memories, so the two of them decided to dedicate their lives to protecting the weakened 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. Pesche explains that he 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, 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, Runuganga appears and attacks the group. Pesche and his group settle down after Runuganga is dispatched by Rukia Kuchiki, and introduce themselves to her and Renji Abarai. Soon after, 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. Szayel returns and proceeds to release his Zanpakutō, creating replicas of Pesche and the others with one of his abilities. After Renji destroys the surrounding area by having his replicas mimic his bankai, Szayel destroys the replicas and uses a different ability to create voodoo dolls of him and Uryū. Around this time, Pesche and Dondochakka recognize the reiatsu of Nel's true form. Wishing to defeat Szayel quickly so that they could assist Nel in battle, they begin to show their true power. Pesche uses his Infinite Slick ability to cause the voodoo dolls to slip out of Szayel's hands. Riding atop Bawabawa, who Dondochakka summons from his stomach moments before, Pesche then wounds the Espada with a slash from his own Zanpakutō, Última. However, Pesche and Dondochakka's most powerful attack, Cero Sincretico, fails to inflict any damage to him. Szayel explains that he had recognized them as Neliel's Fraccion the entire time, and that during his fight with Uryū and Renji, he had analyzed the their movements, reiatsu, and experience enough to predict and exploit a weakness in the technique; essentially, it did not work because they failed to use it from the very beginning. However, the duo's brief intervention buys enough time for the group to be saved by the timely arrival of Mayuri Kurotsuchi. In the ensuing fight, Pesche and Dondochakka are buried in rubble. After Szayel's death, Mayuri's artificial daughter, Nemu, comes across Pesche and Dondochakka while digging through the remains of Szayel's lab. Mayuri orders her to get rid of them; in response, she picks up the piece of rubble the two Arrancar were on top of, and throws it far away. Their current whereabouts after this are unknown.

Powers & Abilities

 * He sprays a translucent green fluid at an object, severely reducing its friction in the process. This has several possible applications, such as when he coats Cirucci Sanderwicci's weapon with this fluid, causing it to harmlessly slide off him on impact. He can similarly use it to make opponents lose their footing or grip on an object. Pesche can spray the fluid over a wide area, or hit a single target with precision. Contrary to its name, the liquid is limited in supply; Pesche states that he named it as such because "Finite Slick" did not sound nearly as cool.

Cero: Pesche is capable of firing a purple Cero from his Zanpakutō, Última. The only time he is seen using it is when he combines it with Dondochakka Bilstin's Cero to create the Cero Sincrético.
 * 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 unique Cero variation that Pesche invented with Dondochakka. The two Arrancar charge their Ceros simultaneously and combine them, creating a far more powerful one in the process. They then fire the multicolored Cero, producing a large explosion on impact. However, there is a small fissure where the two Ceros are not perfectly mixed; Szayel was able to exploit this weakness by touching the fissure, causing the combined Ceros to separate and pass by him harmlessly.

Zanpakutō

 * A sword with a retractable blade composed of Reishi, which constantly radiates blue light. However, when Pesche uses it fire Ceros, the blade emits purple light instead. The sword's hilt is vaguely phallic in appearance, and its guard consists of two crescents that face outwards. Pesche stores it underneath his loincloth.
