I'm reminded of old-school Godzilla & Jet Jaguar (vs.) Megalon & Gigan.
In the end, we see that Gigan has been defeated and flown off, leaving Megalon to suffer the indignity of a tag team beat down at the hands of Godzilla & Jet Jaguar.
The worst for Megalon comes when Jet Jaguar is standing behind Megalon and holding Megalon's arms behind him, while Godzilla runs up the hill and turns around and runs down hill and at some point jumps into the air and literally fly's feet first the rest of the way crashing into Megalon. Megalon takes an aweful hit, gets up, dusts himself off, and Jet Jaguar is right there to put him in that same exposed position again, while Godzilla runs up hill, and does it all over again. Jet Jaguar and Godzilla do this to Megalon about 3-4 times if I remember correctly. It's the most cheesy thing I've EVER seen Godzilla do.
Anyhow, that's how I think Godzilla & King Kong would end up doing to Superman after they wore him down, except that they would each grab a huge tree and toss Supes into the air and bat him back and forth like a baseball or a shuttle cock, back and forth, back and forth.
Yeah, Supes would lose for sure.
and I've been trying to find the footage when John Belushi played him for a one time TV broadcast of Godzilla vs. Megalon.It was only shown once.The later showings didn't have the Belushi-Godzilla footage.
