Forbidden Fruit
With the help of Caesar Clown, the World Government produced a special artificial Devil Fruit, one that could be ingested by those who have eaten a real Devil Fruit without the unpleasant side effects. And one particularly designed to affect women turning them into mindless bimbos. Their plan was simple. Get to Luffy the Pirate through his female companions. Starting with Boa Hancock who once transformed was ordered to share with her friends the benefits of lustful bliss.
