Godzilla got his crowning moment of awesome when he took on the combined forces of the Avengers, Fantastic Four and SHIELD. Especially when they pretty much fought tooth and nail to drive him into the ocean...and that didn't really achieve anything besides pissing him off.
When the Big G wanders into San Francisco, his foot comes down on the block where Hercules is standing. So the Prince of Power knocks over Godzilla. There may not be one other character in history who can claim to have knocked over Godzilla from underneath.
Ant-Man and the Wasp sneaking into Godzilla's ear canal and attacking him there, and it's surprisingly effective. It's really the most effective attack any of the super-heroes ever make against him (even if it is less dramatic-looking than Herc flipping him).
As the Big Guy rampages through New York City, he is wading through the assembled heroes... Until the Mighty Thor shows up and belts him on the snout with Mjolnir. And the formerly oblivious Godzilla staggers back, screaming in agony.
J Jonah Jameson, blowhard extraordinaire, shows his balls of adamantium by yelling unfazed out the window at Godzilla's giant face during one of his famous rants, only realizing at the very end that that maybe wasn't that good an idea.
