4) AIR WAVE
Frustrated by the rise of crime in his Brooklyn neighborhood, law clerk Larry Jordan too to the streets in a costume chockful of that newfangled radio equipment (it was 1942, after all), by a talking parrot called Static (see previous parentheses.) He retired before he could ever test his greatest invention, a helmet that would transform him into pure radio waves, which later allowed his son Hal Jordan (not that Hal Jordan) to become a new Air Wave years later. His G.I. Joe counterpart was part of the Sky Patrol sub-line, and came with a cool parachute accessory, making me wish I’d gotten him when I was a kid.
