Al is a minor character in the series. He is a gangster and the father of Mr. Cat. He is occasionally mentioned by his son but does not play a large role in the show.
Al is said to be manipulative and was supposedly able to trick all the people in a city, including the police, into believing whatever he said. It is not clear to what extent this is true, as it was implied that Mr. Cat may have been exaggerating his accounts of his father's life. He also exhibits violent tendencies towards everyone except his wife, Lola Felicia.
Similarly to Mr. Cat, he is said to be an alcoholic.
He was somewhat threatening towards the other gangsters who worked for him, but they seem to have been on mostly good terms. He has a loving relationship with Lola Felicia. Not much is known about his relationship with Mr. Cat except that the latter harbors some resentment towards him for his drinking habits.
