Banban

Banban is an old man from Water 7. He is the focus of a non canon episode involving Sanji. At first glance, Banban looks like a drunken old man. However, in reality, he is actually an excellent chef with superb skills.

Zeff
Not much is known about Banban's past before coming to live in Water 7; however, it is stated that he once knew Zeff. It is not explicitly explained what exact the relationship between the two of them was; however, a picture of a younger Banban and a supposedly younger Zeff somewhat gives a vague idea of what it was, that they probably were good friends.

Abilities and Powers
He is a very talented chef, with superb cooking skills that even Sanji is awed at, despite looking like an old drunken man.

Past
At some point in time, Banban 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), Banban set up a small restaurant in a little boat in Water 7. He has since lived in the city.
