One of Szayel Aporro Granz's Fracción.
He is significantly larger than the other Fracción, with blue, clown-like hair and a hollow mask covering his right eye and nose. He seems unable to speak and instead communicates through noises that reflect his thoughts. He appears to be extremely sensitive to pain, clutching his hand and screaming after receiving a shallow cut from Renji Abarai, even flipping onto his back and kicking in the air.
When Szayel Aporro grew tired of Renji, he sent his Fracción, particularly Medazeppi, to handle him. After Renji became trapped in a pile of rubble, Medazeppi was about to finish him off with a punch but was interrupted by an arrow from Uryū Ishida, which went through his midsection, killing him.
