Transforms.

SCP-034 has the ability to allow its bearer to take on the appearance of another individual. If SCP-034 is used to cut a piece of flesh from a living individual, and that piece of flesh is placed against the skin of another individual, the second individual would take on not only the appearance, but all physical characteristics of the first individual. Testing has shown that the minimum amount of skin required can be as little as one (1) square centimeter. However, testing has also revealed that the amount of time the transformation lasts is directly proportional to the amount of flesh used. The ratio of time the transformation lasts to flesh used has been measured at approximately one (1) hour for every square centimeter used. Once the time limit has passed, the affected individual will revert to their original form.

Analysis of SCP-034's ability shows that its method of mimicking another individual is nearly flawless. Not only does SCP-034 change its bearer's physical appearance, but their actual physical attributes as well, including height, weight, muscle mass, bone density, hair growth, eyesight, strength, physical medical conditions, and even DNA. The only physical traits that are not carried over in the transformation process are wounds caused by SCP-034 itself.
