He can disguise his appearance through unknown means.
Kevin Sydney (Changeling) Edit
He can psionically alter the formation of his biological cells at will. As a result, he can cause himself to look and sound like an exact duplicate of any human, humanoid, or semi-humanoid being of either sex, wearing virtually any kind of clothing.
Raven Darkholme (Mystique)Edit
Mystique can psionically alter the formation of her biological cells at will. As a result, she can cause herself to look and sound like an exact duplicate of any human, humanoid, or semi-humanoid being of either sex, wearing virtually any kind of clothing. Her control is so exact that she can precisely duplicate another person's retina pattern in her own eyes, finger, palm and skin-pore patterns on her own hands and skin, and vocal cords to match voices to the point of corresponding voice prints. While she can make herself look exactly like a person who is physically bigger than herself, she will not weigh as much as the real person does. Although she can maintain the form a person of her height, weight, and build indefinitely, the longer she maintains the form of a person physically bigger than herself, the greater the strain she feels.
Mystique was once exposed to dangerous levels of radiation in order to save the life of Toad. The process morphed Mystique's appearance to match her more reptilian physique and boosted her powers so that she could now morph her body into taking certain desired physical traits depending on her situation at the time.
Examples of this new ability included: night vision, wings on her back, talons in her fingers, sharp fanged teeth, natural body armor, mermaid-like tail, and she could even compress nearly two-dimensional to glide on air currents, similar to Mr. Fantastic, which she used to survive an explosion.
Since her resurrection by The Hand, her powers have been enhanced to a higher level than they were before, to the degree that she could fool superhumanly acute senses, such as Wolverine's sense of smell, something she couldn't do before her death.
