Orion is Darkseid's more nemesis and the one prophesied to kill him.
I hate how the New Gods are handled by DC. It seems that they just hate New Genesis and portray it almost as worse as Apoliopips and make Darkseid generic dark lord 325
I can understand why they've gone this direction with Darkseid. Given how integral 'hope' is to Supermans entire concept, I can understand why DC really seems to want to shift Darkseid into a place where he can go off against Superman. The 'World of Cardboard' speech probably helps for people like me, who were just the right age to be introduced to Darkseid as a Superman villain through the DCAU.
To be honest, the only New Gods stuff I've ever read was Kings Mister Miracle, and I'm not sure how representative that is for the New Gods and their deal.
(also Morrison and Final Crisis which might be even less representative, since I think Morrison himself ultimately regards Final Crisis as, if not a failure, a flawed experiment)
