I'm watching Gatchaman vol5's first episode, "The Magma Giant, Emperor of Hell", and it's pretty clear that if this one got made into a Battle of the Planets ep (I don't recall if it did) it had to be modified a LOT. Why?
In the ep, there's a Mount Rushmore pastiche at "Bluestone National Park", with three heads that are vaguely like Washington, Jefferson and Lincoln. But instead of TR, there's a face of Jesus.
It gets better...the Jesus face is used as part of the titular Magma Giant monster. Science Ninja Team Gatchaman have to fight a several hundred meter tall Jesus made of magma. Heh.
Update: I found the BotP version. The park is now on "Space Island", a tiny asteroid with atmosphere. The plant for eliminating pollution is just a geothermal tap now. And the Rushmore pastiche is now the faces of the four spacemen who discovered the asteroid, no Jesus allowed. The whole mystery of where the face was seen before is skipped, with Jason jumping to the conclusion in his first line of the ep. Looks like most of Berg Katse's scenes (aka Zoltar) were excised in favor of more 7-Zark-7, too. Needless to say, the scenes of minions going into the lava are cut, too.
