Best Devil fruits for Spying, Espionage or Undercover works.

In the word of One Piece, devil fruits provide the users with immense power. Most of the time, devil fruits grant powers suitable for offensive physical battle. But there are few devil fruits that have powers useful for espionage or undercover works.

There have been several instances in the series where devil fruits were really useful for stealth oprations. I have ranked the best devil fruits for stealth undercover operations. Do you find a devil fruit missing in the list? Let me know in the comments.

Nagi Nagi no Mi

English version – Calm Calm fruit

Nagi Nagi no Mi is a devil fruit that allows the user to create soundproof field. Sound from inside cannot heard outside and similarly sound from outside cannot be heard inside.

Ideal for situations requiring stealth, since it can prevent enemies drawing attention while doing tasks. Techniques granted by it are

• Silent: With a snap of his fingers, Rosinante creates a circular soundproof field to surround himself with.
• Calm: Rosinante cancels all noises caused by him even weapons explosions. Through this technique, the user can accomplish otherwise loud tasks without attracting the attention of his enemies. This technique can also be used on other people.
