Sawatari

is the one of the Bounts, the antagonist race in the Bount arc.

Character outline
Sawatari seems to be the oldest Bount, but this is merely a by-product of his eating habits. He has been consuming living souls for far longer than any other Bount, causing him to age. Like Utagawa, doing so was part of his secret plot to overthrow Kariya as leader of the Bounts. Sawatari is much like the stereotypical "cranky old man," looking down on younger people. He is usually seen sitting in a large chair that appears to be made of wood.

Bount arc
In the Human world Sawatari was fighitng against Rangiku Matsumoto, Chad and Noba. After the Bounts invaded Soul Society, Sawatari confronted Mayuri Kurotsuchi. As they fought, it was revealed that Mayuri had been chasing after Sawatari all along with his sensor device. Mayuri initially wanted Sawatari as a research subject, but became annoyed with Sawatari's continued resistance and killed him instead.

Doll
Sawatari's chair is actually his doll,, which takes the form of a giant fish that can swallow opponents whole; its stomach is a link to another dimension, and anything caught inside is eventually dissolved, leaving the soul for Sawatari to absorb. Being a fish-like entity, Baura travels around by "swimming" through solid objects by means of phasing through a different dimension that only he can access. To emerge, however, the exit point must be large enough to accommodate him. In Soul Society, his power is enhanced, allowing him to move to his dimension in midair. While in his dimension, his and Sawatari's Spiritual Pressure is effectively concealed until Baura chooses to resurface. 

Trivia

 * While it appears that he is the oldest Bount, this is only physically. Sawatari has been known to consume living souls, which ages a Bount if he/she does so.
 * He is the second known Bount to plan to overthrow Kariya for leadership of the Bounts, the first being Ryō Utagawa.
 * In the Icelandic language the name of Sawari's doll Baura is similar to the word Bára which is a wave in water.
