Dondochakka Birstanne is one of Nel Tu's "brothers" and protectors. Like Pesche, he attempts to chase after Nel and Ichigo in Las Noches, but ends up finding Renji instead, who he frequently irritates with his clumsiness and emotional outbursts. Dondochakka has a large, spotted humanoid hollow with a tiki mask and compound eyes. He appears to speak with a yakuza-style accent and is fairly tame in comparison to other hollows. Despite his menacing appearance, he is prone to tear-filled outbursts at the slightest provocation, usually when he's worried about something. As described by Pesche, Dondochakka possesses numerous insect spirits within his stomach. One of these is the worm hollow Bawabawa. He can spit these spirits out at will as allies in combat. In addition, he carries a spiked mace-like weapon inside his stomach. He can also perform a synchronized cero attack with Pesche, called Cero Sincrético. (Source: Bleach Wikia)
