Marvel: Metamorphosis

Jia Jing (Sprite)
She possesses rock-hard skin that she can morph as she sees fit, such as making her hands bigger.

Laurie Tromette (Transonic)
Transonic has blue crystalline/scaly skin that possesses reactive properties that change her physical form to grant enhanced maneuverability and/or speed. In a controlled setting, Laurie morphed under high winds and changed consistency, when she flew into the skies with Oya she underwent a remarkable transformation which had her gain more physical characteristics, her body changed shape to become larger and winged when traveling at high altitudes for more maneuverability and became missile-shaped when traveling at high speeds to become more aerodynamic, though this did not last for long as she had to go back down again.
