Wow. But unless he covered the surface of the planet in yellow, they still could have ripped up chunks of it and used them as weapons, right? Or, I dunno, pulled a John Crichton and used the ring to open a portal from the heart of a nearby non-yellow sun.
Or was it like that scene in ASBAR? If so, I hope Darkseid made enough lemonade for everyone.
Was there ever a version of this encounter after rings became capable of overcoming the yellow flaw?
