Doa Doa no Mi

Doa Doa no Mi (Door Door Fruit): Allows the user to create doors through and on every surface he or she touches, with the possible exception of seastone, and make doors through the atmosphere leading into a pocket dimension. The user can also immobilize their opponent by grabbing them and turning their whole body into a door, though this ability is only mentioned, never demonstrated. "Doa" means "door" (a Western-style door). Eaten by Blueno.

Trivia
In a response to a fan, Oda had stated that if Sanji had eaten the Doa Doa no Mi, it would be like the end of the world. All women would live in fear of being seen naked in the bath.
