Shawlong Koufang

is the 11th Arrancar in Sōsuke Aizen's army. He was a member, and apparently the leader, of Grimmjow Jeagerjaques's Fraccion. His position as the 11th Arrancar before his death, implies that he was the oldest living Numeros.

Character Outline
Shawlong Qufang 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, with a portion droping down to cover the upper-left half of his face, and a long skipe that poits to his right, similar to Mayuri Kurotsuchi's original hat. 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.

History
Shawlong was a member, and possibly the leader, of a group formed by himself, Edorad Leones, Yylfordt Granz, Di Roy, Nakim, as well as two other unnamed Hollows. 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.

Synopsis
Shawlong was part of the group that along with Grimmjow formed the second invasion of Karakura Town. After Scouting for those with spirtual energy they set out to hunt them down, Shalong, along with Nakim come across Tōshirō Hitsugaya and Rangiku Matsumoto, with Shalong taking on the Captain. During his battle he overpowers Hitsugaya even after he had released his Bankai. After noticing that Yylfordt Granz had released his Zanpakutō, Shawlong proceeds to do the same, stating that it would be an insult to a Captain if he did not defeat him using his released form. Shawlong is left to run when Hitsugaya releases his limiter and instantly kills him.
