Mecha-King Ghidorah was defeated by normal Godzilla, and if Burning Godzilla can't defeat Destoroyah, how could normal Godzilla, and therefore Mecha-King Ghidorah defeat him? Well, to be fair, both variations of Destoroyah's second most powerful form were defeated by Godzilla Jr. single-handedly, who is even weaker than normal Godzilla (from King Ghidorah on anyway).

But any monster or weapon with attacks that include extreme heat or extreme cold can deal serious damage to Destoroyah.

Personally, I still believe Spacegodzilla could beat Destoroyah too.
