Kukkapūro

is a Números in Sōsuke Aizen's army, holding the number 35. He is also a companion of Yammy Llargo.

Appearance
Kukkapūro has the appearance of a puppy with a Hollow mask. He is covered with soft, white fur. His mask has large eye sockets and two small horns protruding above his long, drooping ears. He has the number 35 tattooed on his back.

Personality
Kukkapūro follows Yammy around because he looks similar to his owner when he was alive, even though Yammy did nothing to take care of Kukkapūro.

History
One day, Kukkapūro woke up in Hueco Mundo as a Hollow, having lost most of his memories about his past life. He remembered a large hand petting his head and calling him "Kukkapūro". In Hueco Mundo, Kukkapūro survived by breathing the Reishi in the environment. At some point he encountered Yammy Llargo. With just one glance, Kukkapūro thought "He is similar to the person important to me". Kukkapūro tried his best to run after the much larger Yammy and accompanied him thereafter.

Fake Karakura Town arc
As Yammy is eating, Kukkapūro starts barking at him. Yammy angrily throws a bone at him, forcing Kukkapūro to dodge it. Yammy leaves the room with Kukkapūro following at his heels. When Yammy is defeated in battle, Kukkapūro approaches him. As Kukkapūro barks at him, the Espada briefly awakens. Yammy asks why he followed him and then dies.

Some time later, Kukkapūro emerges from the ruins inside Las Noches to greet the returning Tier Harribel and her Fracción. Kukkapūro stares at the four Arrancar as they talk amongst themselves. They start to leave, but Emilou Apacci looks back at him and tells him that he will be killed if he just sits there. She approaches and picks him up. Kukkapūro tries to get away from her. At Cyan Sung-Sun's behest, Apacci puts him down as he clearly wishes to stay put. Franceska Mila Rose pats his head and they leave. Kukkapūro sees them off, still thinking about his deceased master.
