Dondochakka
Birstanne

Dondochakka Birstanne is the larger and louder of Nelliel Tu Odelschwanck's two Fracción, a heavyset Arrancar in a polka-dotted bodysuit whose Hollow mask covers his entire head. He cries constantly, speaks in an exaggerated regional accent, and keeps a giant worm called Bawabawa inside his stomach, which he coughs up when transport is needed.

He and Pesche Guatiche have spent years playing eternal tag across the sands of Hueco Mundo with a Nel who does not remember being an Espada. Nnoitra Gilga cracked her mask from behind and left her as a child, and rather than tell her what happened, the two of them built a life out of a game she could win. When Ichigo Kurosaki's group first sees them chasing her, they assume it is an attack.

The competence is hidden under the same layer as Pesche's. During the fight against Szayelaporro Granz, Dondochakka drops the act, produces a kanabo along with Bawabawa, beats two Fracción with it, and fires a coordinated Cero Sucio with Pesche. He is not a fighter by preference and the series does not turn him into one. He is a bodyguard who decided the job was to protect her from the truth as much as from anything in the desert.
