: Really? I didn't see anywhere in GURPS that Fetch aren't
: made of energy--just that they do have a definite
: shape. And there's lots of ways to discharge energy
: that would be undetectable to the human eye.
Actually, it does say, in effect, that they aren't made of energy. If they were made of energy, they would have the No Physical Form disadvantage. Which they don't. What they do have is a weakness to direct sunlight on skin, and the customisation note that they probably look horrid under their leathers, and, if so, should have the appropriate appearance disadvantage.
