Edit
Some or all of the character's skin is made of plastic. As a metal skin, a common feature of many cyborgs and androids that are not designed to look convincingly human, and is also common to some dolls and other similar creatures.
Plastic skin can be painted in a natural color, but differ in shine and the presence of joints, or have any other colors. Most often white, gray or black.
Don't use this tag for characters that canonically have metal skin unless it actually appears to be made of plastic.
This tag shouldn't be used for non-humanoid robots since they aren't typically meant to have "skin" anyway.
