Yep! Megaro-Goji (thats what they call the 1973 Godzilla suit in japanese) appeared on TV! On a show called "Zone Fighter" as well as King Ghidorah and Gigan! Toho brought Godzilla to the small screen after they realised the mosnter wasn't pulling people into the theaters for his big screen adventures. You think Godzilla fought weird monsters in "Godzilla vs. Megalon" you wont believe the creatures that Godzilla encounters! Godzilla also does some things that make his tail slide look realistic!
Below are pictures from the shows that Godzilla appeared on! Click for a full sized image! Sorry about the odd shapes of the pics, but images from this show are rare so this is the best you'll get.
