You Can't Beat the Funnies For Action!

Okay, JOHN CARTER I know--Edgar Rice Burroughs' Mars-bound, Princess-loving soldier. MR. DISTRICT ATTORNEY is presumably from the radio show of the same name. But "REX," KING OF THE DEEP? Does Namor know about this guy? And what about SPEED MARTIN and SKY RANGER? Can you get more generic-sounding than that? Oh, and guys? Thanks for warning us that PHANTASMO appears ONLY in THE FUNNIES! That way, we don't have to worry about running across him anywhere else so it's safe to read your competition!
