Anyway, how strong they are depends on what they do. If they work all day (or close enough, anyway) then a beowulf could likely destroy an entire city. If they sit around and do nothing, there's a reasonable chance they could still manage to kill an ant, provided it didn't move too fast.
Of course, I'm not saying what you'll see in the comic.
But you knew that, already.
