Avalo Pizarro

Avalo Pizarro is a new member of the Blackbeard pirates. Known as "Corrupt King", he was one of the criminals who was given a life sentence in Level 6 of Impel Down, where their crimes were so atrocious they were effectively erased from history itself. He has many cat-like characteristics, such as his slit pupils, mane-like hair, cat-like patterns on his jacket and speaking with the word "Nya", the Japanese equivalent of "Meow".
