Accino Family

The Achino Family is a family of Bounty Hunters who only appeared in the anime-only Ice Hunter Arc, though designed by Oda himself. Their leader/patriarch is Don Achino, and they serve as the main antagonists of the arc.

Strength
The Achino Family seemed to be strong, capable of defeating powerful targets such as the Phoenix Pirates and taking their flag as a trophy. They were also able to give the Straw Hat Pirates quite some trouble. They also use the geography of their headquarters, Hyokaido, to give them a home-field advantage against their opponents. Their father, Achino, is the strongest member of the family.
