Bawabawa

, is a giant, eel-like Hollow whose mask consists of a simple plate on his head with a pair of horns. He acts as both a pet and transportation for Pesche, Dondochakka, and Nel Tu. Bawabawa tends to get upset for not being included in the group's super sentai-styled introduction sequences.

Character Outline
Initially, Pesche and Dondochakka say that Bawabawa can't survive without sand, thus explaining why Bawabawa doesn't follow the group into Las Noches. During a battle with Szayel Aporro Granz, however, Dondochakka reveals the ability to spit Bawabawa from his mouth. Despite his fearsome appearance, Bawabawa is actually rather emotional and not evil, but will fight if necessary.

Bawabawa appears on one of Gin Ichimaru's "Arrancar Research Time" segments. Gin comments on his size and Bawabawa humorously tries to swallow him, forcing the latter to use Shinso to push him off.

Hueco Mundo Arc
Bawabawa is first seen playing eternal tag with Nel tu, Pesche and Dondochakka, with the 3 Hollows chasing Nel. Unfortunately, Chad, Uryu Ishida and Ichigo Kurosaki believe that Bawabawa was trying to kill Nel, and Chad assaulted Bawabawa. After the misunderstanding was cleared up, the 7 have a 'meeting' with the giant Hollow Lunuganga. When Ichigo's getsuga tenshō fails to destroy Lunuganga, Nel informs Ichigo that Lunuganga's weakness was water. However, unable to find any water, the group are still unable to hurt Lunuganga. However, the tables are turned when Rukia Kuchiki, who had come with Renji Abarai, destroys Lunuganga with her ice-type Shikai.

Later he is seen in the battle between Szayel Aporro Granz, when Dondochakka releases him from his mouth to assist him and Pesche in battle. Then, Pesche explains that Bawabawa is actually one of many spiritual combat insects that dwell within Dondochakka. After their Cero Sincretico technique, Bawabawa is not seen, presumably back inside Dondochakka's body.

Fake Karakura Arc
Bawabawa, along with Nel, Pesche and Dondochakka have yet to play a role in the battles; they will probably be reunited soon, However Gin announced in an omake that they will not be seen during this arc.
