A full robot that is designed to look either completely or primarily human, very frequent in general science fiction and cyberpunk works. They may appear male, female, or androgynous; however, female androids are the most common in anime (they're called gynoids). Some androids have small robotic appendages or markings to make it apparent to the viewer that they are not human. The most common of these are robot ears, robot joints, mechanical wings, and attached cables.
By rule of thumb, androids should look at least 80% human, usually having something resembling skin (though it needn't be skin-colored) and fully human faces.
