I forgot to mention two feats for the strongest Godzillas.
Final Wars Godzilla blasted the 100,000 ton Kaiser Ghidorah into space and blew him up from ground level in Tokyo.
Godzilla Earth destroyed the entirety of Los Angeles and Orange County in a single shot.
Godzilla Earth was butried under the entirety of the Himalayas including Mt. Everest he proceeded to blast his way out and melt down the entire mountain range lol.
But you know, Hulk and Hulkbuster shattered windows and knocked a man over from they're fistbump.
