Double (二に倍ばい, Nibai?) Double allowed the user to create a copy of anything, two at a time, through touch. With the quirk, the user could produce replicas of anyone to provide support in numbers. In order to conceive a perfect clone, the user required knowledge of precise measurements and physical features of the person or object they were replicating. Doubles possessed the same personality and abilities as the original, making it hard to distinguish them from the real person at a first glance.
