Picture #2

The sky appears to be a reflection, or possibly a mountain of some sort. More likely, it's Earth 2, back to get revenge for the end of Crisis on Infinite Earths, when Earth 3 and Earth 1 combined to create Earth Prime. All of the superheroes from Earth 2, who were actually the villains, discover a way to rejump through the multiverse, and in order to exact their revenge, though they can't exact anything, since they were wiped out from the antimatter created by the Anti-monitor. Regardless, they intend to crash earth 2 into earth Prime. All of this was recreated from memory, as it might actually be Earth 4 whose superheroes were villains, it's hard to keep track of.
