Alvida

Alvida (アルビダ) is a female pirate captain, and one of Luffy's earliest enemies. Initially, she was an obese woman. After her defeat at the young pirate's hands, she leaves her crew and finds the Smooth-Smooth Fruit and consumes it, becoming a slender girl. At one point, she meets and allies with Buggy the Clown. Her attempt at revenge on Luffy to have him publicly executed by Buggy fails. She and the pirates of Buggy are captured by Smoker, but eventually escape.

She appears in One Piece: Pirate Warriors 3 as a non-playable character.

Fighting Style
Alvida fights with a spiked club called the Iron Mace. When she consumed the Smooth-Smooth Fruit, she was given an increase of speed, to slip through things at high-speeds.
