Double (二に倍ばい Nibai?): Jin's Quirk allowed him to create an exact duplicate of anything, living or not. To duplicate something, he needed to know the precise measurements and characteristics. He was limited to only two duplications at a time. The duplicates were less durable than the original; the second duplicate was even less durable than the first. The clones didn't disappear; instead, they disintegrated into a mud-like substance after taking a certain degree of damage.
