Exequias

The are Arrancar that form an execution division in Sōsuke Aizen's army of Arrancar.

Outline
They are responsible for dealing with rebels and intruders in Las Noches usually terminating both hence their name. They are the equivalent of the Soul Society's Special Forces.

The Espada, much like with the Números, seem to have a level of control over the Exequias: Szayel Aporro Granz ordered them to kill the invading Ryoka and retrieve the bodies of their defeated opponents, though how much control they have is uncertain. After being summoned by Szayel, the Exequias proceeded to act under Rudobōn's command.

Uniform
The uniform of the Exequias is the custom white jacket and hakama worn by all Arrancar in Aizen's amry. All Exequias however wear a similar skull-like helmet over their heads. Rudobōn's seniority is reflected in the bull-like mask he wears compared to the human like skulls of his subordinates.

List of Exequias

 * Rudobōn - He is the Captain of the Exequias but his strength level is unknown.

Trivia
It is considered by some fans (or at least, on some of French Bleach forums), after seeing the "Quimera Parca", that the Exequias were also only one, and that when they all release their Zanpakutô, they fuse into a big powerful Arrancar. However, this is totally speculated without any proven fact.
