    x ray vision, pretty sure you need to expose things to x rays to see skeletons. You gonna walk around irradiating people with an x ray source?

      Eh I don’t think this is meant to say it’s actually x-rays. Wouldn’t that require a receiving end on the other side of the person?

      Sort of. You don’t really see things on x-rays, you see shadows created by denser material.

      Projecting X-rays at your target wouldn’t be very useful, as they are usually absorbed rather than reflected back (I think). You’d be able to see if somehow the subject got between you and a significant source of x-rays
