When an image displays the ability for characters to see through clothes, walls or other objects. This can either be accomplished via some device (such as x-ray glasses or an x-ray phone) or via the innate ability of a character (such as Superman).
If there is no indication the x-ray would be visible to any characters (even offscreen characters), and it is simply drawn for the viewer's benefit, use the x-ray tag instead of this one.
