Believe it or not ...

Shmails made a great custom of the Greatest American Hero. "Hey!" you shout at me, "that's a TV show!" You can even watch it on Hulu. Apparently William Katt, star of the 80's series, launched Catastrophic Comics, a company that released a limited series based on the TV show. You can see a preview on that site, but I have no idea if it lasted past its initial release in 2008.
