Dondochakka Birstanne

is one of Nel Tu's Hollow "brothers", as well as one of Nel's protectors.

Appearance
Dondachakka is a large, polka-dotted, arrancar with a tiki mask and compound eyes.

Personality
He appears to speak with a yakuza-style accent, often saying "Don'tcha Know (-de ariusu in Japanese)!" at the end of his sentences. Despite his menacing appearance, he is prone to tear-filled outbursts at the slightest provocation, usually when he's worried about something.

History
Dondochakka once served Nel when she was an Espada, but had his mask torn off by Nnoitra Jiruga and Szayel Aporro Granz, and was left for dead along with Pesche and Nel. After realizing that Nel had reverted to a defenseless child, he and Pesche pledged to protect Nel by never telling her about her former life. Furthermore, both he and Pesche modify their appearances and hide their own identities, so they can keep Nel's memories as the former 3rd Espada from returning to her.

Hueco Mundo arc
He travels Hueco Mundo with Pesche and Nel Tu, and their pet, Bawabawa. Like Pesche, he attempts to chase after Nel and Ichigo in Las Noches, but ends up finding Renji Abarai instead, whom he frequently irritates with his clumsiness and emotional outbursts. When Szayel Aporro Granz makes clones of him, he does not copy his spots.

Powers & Abilities
Stomach Containment: As described by Pesche, Dondochakka possesses numerous insect spirits within his stomach. One of these is the wormlike Hollow Bawabawa. He can spit these spirits out at will as allies in combat. In addition, he carries a kanabō inside his stomach,it is possibly his zanpakto and when he pulled it out he called it his katana.

Cero: He can also perform a synchronized Cero attack with Pesche, called cero sincrético. Both fire unusually colored ceros, which form into one, "wonderfully powerful" (Said from Szayel Aporro Granz in the original Japanese version) Cero, that produces a big explosion upon impact.
