Genzo

As Bell-mère was growing up, she was known as the village trouble maker (he refers to her as you little thug). Her reputation caused him to express concerns over the children's well-being when she announced she was adopting them as her daughters. He has had close ties with both Nami and Nojiko since they were kids because of his concern over their adoptive mother's capabilities and spent most of his time watching out for them. Eventually this grew into a desire just to see all three of them live together and grow together as a happy family.

After their mother's death, he became concerned for the happiness of Nami and Nojiko, as he had grown into a father figure to them. He and the other villagers realized Nami would never join up with Arlong's crew without good reason. His concern for her and Nojiko's well being also led him to promise Luffy that he would hunt him down and kill him if he ever took away Nami's smile.[5]

He kept the town together after Arlong took over the island, making sure everyone was safe and able to pay Arlong's tax. Whenever there was trouble between the villagers and Arlong or his crew, he took full responsibility for everything so the villagers would not be punished. He helped keep the village together to give Nami the time to complete her plan to save the village. When her 8 years of hard work to save them fell apart after Arlong's betrayal, he decided enough was enough. If they were going to die, they would die trying to fight Arlong even with Nami pleading that she can just start all over again.[6]

Genzo also has a perverted side, as he becomes quite flustered when Bell-mère offered to pay back the items the latter stole "with her body"[7] but when Nami parroted Belle-mere's words, Genzo just yelled at the girl not to pick up her adoptive mother's bad habits. Genzo has a blown-up image of Nami's wanted poster, in which she appears in a bikini, despite stating that she shouldn't have posed like that as it would draw the attention of more

Genzo is an average-sized, dark-haired man with a thick mustache; his face typically shows a stern expression. His only known outfit is a brown, short-sleeved policeman-esque uniform with sandals; for more than a decade, he wore a pinwheel in this uniform's cap as a means (and later, a memento) of cheering up Nami.[1]

After the Arlong Pirates invaded Cocoyasi Village, his face and body were heavily scarred by an attack from Kuroobi.

Some time after the Summit War of Marineford, he began to grow a bit of stubble on his chin.
