Given the Krolotean's response to seeing Blue Beetle, I'm inclined to think that the new Partner is connected to The Reach (the species who, in the comics, create the Blue Beetle scarabs as the vanguard of invasions).

That said, I'm certain that Darkseid is involved somewhere - the presence of Glorious Godfrey (traditionally a servant of the Lord of Apokalips in the comics) in season 2 and various items of Apokaliptian tech in both seasons suggests that we may yet see Darkseid's machinations, though likely later rather than sooner (end of the season at the earliest, IMO).
