No one knew from where they came, or what kind of race they were. They were just an alien bunch of people that had appeared out of nowhere and had managed to make a standing on Earth.
Of course, it wasn't like humans on Earth welcomed their arrival on this planet, as countless wars had been waged over all the history of Earth.
Unfortunately no matter how bloody and scary these wars became there didn't seem to be any winning side, as neither the aliens nor the humans of Earth were gaining an edge.
Normally these powers would still be fighting each other with all they had, but the appearance of the Justice League provided the opportunity for a cease-fire.
And the appearance of an even greater danger managed to turn them from enemies to allies, whether they wished it or not.
