😐...clears.

Thanos might aggravate him for a bit but that's it.

These guys are going all out

He eats them.

😑 this would have to be a very weak version of the devourer galactus. lifebringer slaughters this and likely doesn't work up much sweat taking them out collectively. /shrug

If Thanos, Superman, Wonder Woman or Thor have no external source of advantage, than Galactus pretty much clears this list....and quite easily.

You could put them all together and he would still fodderize them
