If you've seen the new horror movie A Quiet Place, you know that the antagonists are "an invasive predatory species of unknown origin [that] has replaced humans at the top of the food chain. The creatures are large, fast, and have a seemingly impenetrable armor shell which protects their entire bodies. The creatures are blind but have incredible hearing acuity—which they use to hunt their prey. Within three months of their arrival nearly all of humanity has been wiped out." These creatures first appeared in the year 2020 and were invulnerable to the most powerful weapons deployed by humanity's military forces (don't know if they tried using nukes, but presumably, no).

So that was on whatever Earth we see in A Quiet Place. What if those same creatures attempted to do the same on MCU Earth or DCEU Earth? Could the Avengers or the Justice League stop the creatures and save humanity?
