Can composite Godzilla destroy Coruscant?

I would have to say Composite Godzilla (if we take into account for Shin Godzilla's ability to metamorph at will [I refuse to call it evolving because Shin Godzilla defies the basic laws/rules of Evolution]) would dominate Coruscant

keep in mind Coruscant is all one Huge city and its buildings are Many kilometers tall its a loooong way down to solid ground so unless big G is even bigger than Godzilla Earth hes guna have some issues.

XarKhaan,
What issues? It's not like he's going to leap off the edge. And even if he tripped, Godzilla survived atmospheric re-entry in Godzilla: King of the Monsters. And if he can't get back up (which is unlikely, because this is a composite Godzilla and he would be able fly) the composite powers include atomic breath that can not only exit the atmosphere, but take down whole ships and asteroids.

The only thing having trouble is Coruscant.

Yes, if you mean a composite of all of them.

Several of them are outright planet-busters under the right circumstances, several of them are outright immortal, etc., particularly the comic book versions of Godzilla.

IDW's Godzilla iterations in particular have some of the best feats. He killed blew up a planet in a beam struggle with Spacegodzilla while trapped in Hell AND killed both God and the Devil, after which he pulled himself out of Hell. Another version killed the Greek Gods despite them being stated by WoG to be immortal like their classical selves AND came back into being despite being vaporized by Zeus.

Then there's another IDW Godzilla overpowering a barrier powered by a black hole. There's also the anime trilogy's Godzilla in the novel backstory destroying Gorath, which was a meteor 30km across with the same mass as Earth's moon packed into that tiny frame.

The original Godzilla would be able to deal some damage before dropping. Kotm Burning Godzilla would have obliterated Coruscant.
