Shawlong Koufang

Shawlong Koufang is the 11th Arrancar, implying that before his death, he was the oldest living Numeros.

Appearance
Shawlong Koufang has a long face and black hair, which is braided and usually hanging over his shoulder. What remains of his mask is on the top of his head, but a portion drops down covering the left half of his face. The location of his Hollow hole is in the center of his abdomen, but is hidden by his Arrancar uniform. Shawlong is an intellectual, or at least an analyst, able to confidently state the nature of his opponent's powers. He is also somewhat well mannered and well spoken when compared to his comrades. He is killed by Tōshirō Hitsugaya during the raid on Karakura Town.

Past
Shawlong was a member, and possibly the leader, of a group formed by himself, Edorad Leones, Yylfordt Granz, D-Roy, and Nakim. They wanted to become vasto lordes by eating other hollows and thereby decided to join forces with the adjuchas-class menos, Grimmjow Jeagerjaques, whom Shawlong proposed be their "king". However, upon learning that they could evolve no further, Shawlong asked him to devour a part of each of them, as this would both halt their evolution and prevent them from returning to being a lesser Hollow, something that apparently all Adjuchas or Higher level Menos fear.

Zanpakutō
Shawlong's zanpakutō is named Tijereta (五鋏蟲（ティヘレタ）, Tihereta?, Spanish for "whoop," Japanese for "five-pincered insect"). It is released with the phrase "snip" (裁て, tate?). When released, Shawlong grows armor covering his arms and upper chest with his hands transforming into long claws, his mask extends down to cover the left side of his face and his queue becomes a tail with claws.
