Banban

Old Man Banba (バンバン爺, Banba-ji) is an old man from Water 7. He is the focus of filler episode involving Sanji.

Appearance
At first glance, Banba looks a drunken old man. However in reality, he is actually an excellent chef with superb skills.

History
Not much is known of Banba's past before coming to live in Water 7 however it is stated that he once knew Zeff. It isn't explicitly explained what exact relationship between the two of them was, however a picture of a younger Banba and supposedly younger Zeff somewhat gives a vague idea of what it was.

At some point in time, Banba came to Water 7. There he discovered the special salt that was left by the Aqua Laguna. He also discovered the beautiful women of Water 7. Wanting to use the salt for his culinary creations (and to get to know the women better), Banba set up shop in a little boat in Water 7. He has since lived in the city.
