True Mimicry

Like it's parent jutsu, it is a technique that allows the user to mimic a person's appearance. However, it's power is beyond that of simple transformation. Unlike its forebear, it not only copies the appearance, but the target's abilities as well. This includes any taijutsu, ninjutsu, kenjutsu or other specialty, as well as the underlying techniques known by the targets. It even allows the user to copy the target's tendencies, personality, and verbal tics. Thus the user becomes a carbon copy of the original, with differences in chakra signature or ability become impossible for dōjutsu users to see. However, continued use poses danger to the user's psychological health, as personalities and tendencies from the people that are copied are then accumulated into user's own personality. This can intense psychological strain that could result in multiple personality disorder or madness, among other things.
