The invisibility thing another interesting possibility. Instead of the "sees through stuff" power, his symbol reference that no one can see him. I wonder if it could be like the ability originally attributed to Blake. "Her ninja power allows her to become one of those black-shadowy background characters" which fell into disrepute once the background characters became "fully fledged" as of Volume 2. So, in other words, Qrow has the ability to disguise himself as a shadow of himself.
