Rudbornn Chelute

is an Arrancar in Sōsuke Aizen's army and the captain of the Exequias.

Character outline
Unlike most Arrancar, his face is hidden. He is distinguished from the other Exequias with his bull-shaped skull, instead of the typical human-shaped skulls his subordinates wear. He seems to know Dordonii.

Synopsis
He and his subordinates clean up after each battle, collecting data before killing any survivors: they killed Dordonii and Cirucci Thunderwitch off screen for failing to win against their opponents, and prepared to do the same with Chad and Gantenbainne Mosqueda before being approached by Retsu Unohana and Isane Kotetsu. Surprised by the arrival of a captain-level Shinigami, Rudobon and the rest of the Exequias withdraw in order to avoid conflict. He and the rest of the Exequias appear in front of Ichigo in order to prevent him from reaching Ulquiorra and Orihime however, Ichigo's friends engage the Exequias in order to allow Ichigo safe passage. Rudobōn told the others not to let themselves be distracted by this though and made his way to his target before being halted by Rukia, who caught his sword and hand in ice. Soon after, he is able to break the ice fairly easily.

Zanpakutō
The name of his zanpaktou is Arbolar
 * Resurrección - the command is: “Grow up, Arbolar”
