That's more an insult to the empires fought than a point to the Wave.
Their big weapon, after all, was a planet destroying bio-engineered organism. Not only does DC space have things that do that naturally (and more effectively), they've got natural space organisms that do far more (sun eaters), and Apokolips has bombs the size of suit cases that can destroy planets, as well as weapons that turn entire suns into giant, living cosmic lasers.
Add in their elite, their legion of parademons that can't actually be killed, their legion of foot soldiers, and the best tech in comics and it's a no brainer.
