The Big Mom Pirates are one of the most powerful pirate crews that fans have seen in One Piece. Up until recently, they ruled over a significant portion of the New World, which made them a force to be reckoned with on the seas. The Big Mom Pirates oversee Totland, a significantly massive country composed of several small islands. The ruler of Totland is the former Emperor, Big Mom. Fans have seen a significant portion of the post timeskip of One Piece focus on the Big Mom Pirates, and, in Wano, they were dealt a significant blow, when the emperor, Big Mom, finally fell.
