Mystique (Marvel Legends)
"Whether operating undercover or fronting a band of thieves, the metamorphic mutant known as Mystique possesses an almost pathological capacity for deception. A mutant metamorph, Mystique can psionically shift the atoms and molecules of her body and clothing so as to mimic the appearance of any human, humanoid or semi-humanoid being of either sex. Her control is so precise she can exactly replicate another person's retina, finger, palm and skin-pore patterns; even vocal cords are not beyond her ability to duplicate. A sworn enemy of the human race, Mystique wages a one-woman war against those who hate and fear mutants! Features 27 points of articulation and includes a 24 page custom posterbook and the ""lower torso"" of the Sentinel. 6"" scale."
