Apokolips vs. Oa

The entire planet of Oa Star had been covered by Apokolips's Mother Boxes with an energy field, completely severing Oa Star's connection to the outside world. Oa Star had been placed within another dimensional spacetime, isolated and without aid. Countless Parademons blanketed the sky in dense swarms, their membranous wings vibrating at high frequency with a droning hum. The Parademons on the ground crawled like zombies whose lower halves had been severed.
