Episode 412

"The Heartless Judgment! Marguerite Turned to Stone!!" is the 412th episode of the One Piece anime.

Short Summary
Luffy looks at Boa Hancock's back and notes that he has seen what was on it before. Hancock tries, but fails to turn him to stone with her powers when he mistakes her Mero Mero no Mi abilities for Foxy's Noro Noro Beam. Luffy tries to escape but gets captured by the Kuja pirates and is brought to the execution arena. Marguerite confesses bringing him to the island, and Hancock turns her and two of her companions to stone. Enraged at the Kuja's lack of empathy for Marguerite, Luffy punches out Bacura, the panther sent to execute him. Hancock's two younger sisters, Boa Sandersonia and Boa Marigold, jump into the arena and, using their Devil Fruit powers, transform into snake-women to fight Luffy.
