With this answer, we learn New 52 Darkseid (and the Apokolips Pantheon) are considered unique across the universes (or at lease they themselves consider being so). In World's Finest #27, we learn from Intri that (most probably) Darkseid plans to raise Earth 2 Kal-El as a Lord of Apokolips.
My question is why is Kal-El the chosen one, considering Intri is at this very moment on a planet full of alive Kryptonians to pick from ?
And, let's say the Kal-El choice is justified (by his future self being freaking Superman, by something Darkseid could have seen in other universes, by him being a natural born Kryptonian, or else ?), why does Intri puts so much effort in trying to capture this specific version of Kal-El, as seen in World's Finest #28 and #29 after that ?
