Enigma

Enigma (エニグマ) is the Stand of Terunosuke Miyamoto, featured in Diamond Is Unbreakable.

Appearance
Enigma is a dark-colored humanoid Stand. Its body is covered in standards resembling the pistons of a saxophone or trombone.

Ability
Paper Seal: Enigma is able to seal objects and people, including the user, in paper. Once folded closed, a simple piece of paper can hold a single person, or even an entire taxi. The condition of the object or person trapped in the paper remains the same as long as the paper is kept in one piece (i.e hot soup stays hot; ripped paper can damage the captive).

To trap a person in paper, the user must discover the habits the target displays when afraid. Once he has witnessed them display their habit enough to be 100% sure it's their "tell", the Stand captures the target. In this situation, Enigma is invincible, and Stand powers are rendered useless. An object can be released by simply opening the paper.
