Dondochakka Bilstin is a big Arrancar with a yellow body and black polka-dots over his skin. He wears a large mask, with pink patterns, and has large yellow eyes.
Dondochakka is a very sensative Arrancar and tends to break into outbursts of tears for any little thing. He is also very caring as he worries a lot about Nel, and freaks out if he gets seperated from her.
Dondochakka posesses a very unusual ability to keep various things stored in his stomach, like Nel's, Pesche's and his own pet, Bawabawa. He also keeps a strange club in his stomach, which he revealed during Uryuu Ishida's and Renji Abarai's battle with the 8th Espada, Szayel Aporro Granz, and refers to it as his "katana".
He also posesses a unique "Cero Sincrético" (synchronized cero) move with Pesche Guatiche, by combining both their Cero's.
Dondochakka, along with Pesche, were originally Nel's Fraccion, before she lost her memory and her adult form. She reverted to a child form and lost her memory thanks to Nnoitra Jiruga and Szayel Aporro Granz, and Dondochakka and Pesche also lost their hollow masks, and then decided to protect Nel from harms way, by making sure she never found out about her past.
