Aisslinger Wernarr

is a low-level Arrancar and one of the gatekeepers of Las Noches.

Character Outline
Iceringer is either an incomplete Arrancar or one that never learned how (or cared how) to seal his power in a form of a Zanpakutō, stating that he abandoned human form for greater power. He has four arms, each with three fingers that he uses to shot his Uňa Tirotear from. His Hollow mask is in the shape of a beak with only the upper-left quarter of his mask showing his face. While he does not appear to have legs he is able to use Sonido and his speed is able to match that of Uryū Ishida Hirenkyaku.

Synopsis
Guarding the underground passage to Las Noches along with Demōra, Iceringer serves as the guardian of the entrance to Las Noches. When Ichigo’s group arrive attempting to enter Las Noches, they are halted by Iceringer and Demōra who challenge them in an attempt to halt their progress. Iceringer proves to be more than a match for Yasutora Sado who can’t keep up with his speed. Chad and Uryū switch opponents and Iceringer decides that its time to finish the battle off using his special attack,, which can fire one hundred and eight projectiles. Iceringer is shocked to see that his attack is nothing compared to the twelve hundred shots Uryū can fire consecutively. Uryū leaves Iceringer near death and tells him to inform Aizen that it is not the Shinigami that he should fear, it is the Quincy. Iceringer laughs and musingly says that Aizen fears no one, and that it is the this reason that they, the Arrancar, creatures born from fear follow him. Upon his defeat, along with that of Demōra, the battlefield within the underground pathway collapses (as it is designed to collapse upon their defeat), and Ichigo, Uryū and Chad are thrown out into the Hueco Mundo’s suface by the dust and debris.
