Bandits

Bandits (盗賊) in One Piece are regarded as the opposite to pirates in terms of views and ideals (and from what is seen in the series, also strength). Unlike pirates, most bandits tend to harass local villages and towns, rarely traveling to sea and remaining mostly grounded to the landscape they have come to know.

Mountain Bandits
The only known groups of bandits are Mountain Bandits (山賊), many of whom are based around the Corvo Mountain on Dawn Island. Higuma stated that the differences between the two groups means they do not get along at all with each other. Also as they don't seem to be very strong they don't represent a major threat to the World Government. However, that doesn't mean that they are without infamy: Curly Dadan and her &quot;family&quot;, who lived in the same island as Higuma, is stated to have accomplished a number of crimes "as many as the stars in the sky".

Trivia
