Surface

"Once I've become your copy, you have to pose the same way that I do. In short I'm a doll that "manipulates"!"

- Surface, Chapter 290

Surface (サーフィス（うわっ面）) is the Stand of Toshikazu Hazamada, featured in the fourth part of the JoJo's Bizarre Adventure series, Diamond is Unbreakable. It is bound to a wooden mannequin and can copy someone's appearance. Moreover, if Surface and the person they copy make eye contact, Surface forces its victim to copy the movements it performs.

Appearance
Surface is a wooden human-sized mannequin, with five large screws in its body. One screw is in the middle of its face, while the remaining four are in each shoulder and knee. While activated, Surface takes on the appearance of another person, matching their voice, mannerisms, and clothing. However, the screw on its forehead still appears.

Befitting its wooden nature, Surface is generally portrayed as light brown in most media.

Personality
It has no personality until its abilities are used, upon which it adopts the personality of whomever it is copying at the moment. While acting as a doppelganger of Josuke, it makes fun of its user, Hazamada, for hitting the Stand and hurting his hand on its wooden body. It is also smug towards Hazamada because the Stand is more popular with girls when it resembles Josuke. However, the Stand is still willing to serve its master without question.

Abilities
Although physically underwhelming, the only noteworthy characteristic being its speed, Surface is a menacing Stand because of its two powers of mimicry and control over people.

Mimicry
Surface's primary ability is to copy the appearance of another person.

If the mannequin faces someone, it will perfectly copy that person's appearance, voice, and mannerisms, down to the fingerprints, as noted by Josuke. However, a screw on Surface's forehead enables people to tell them apart. As a Stand bound to a mannequin, no damage done to Surface will be reflected in Hazamada.

Surface still remains a wooden mannequin on the inside, causing Hazamada to hurt himself while punching his Stand. If a piece of the mannequin is cut off, that area will return to its wooden state.

Forced Synchronization
When Surface impersonates someone, it can force that person to imitate its movements. This prevented Josuke from hitting it by standing still, making it impossible for him to move and strike it - even with his own Stand due to its limited attack range. However, Surface must stand in front of its victim for it to work.
