With the upcoming showdown beween Zeus and Darkseid, I am really curious what separates a New God from and Old God, aside from the technological advances of a New God. Let's just keep it simple with these two immortals first to keep it simple:
Similarities:
Both can teleport
Both have super strength
Both can make themselves larger (gigantic)
Both can create life (though Darkseid can only bring someone back to life that he has personally killed with the Omega Beams)
Both are good fighters
Both can teleport themselves and others
Both can fly
Both can sort of create Avatars of themselves
One can trap you into som dimensional plane and the other can trap you into Tartarus (lol)
Differences:
Zeus can weather manipulate, transform into animals, summon lightning, curse spell, and matter manipulate by transforming things into whatever
Darkseid has the Omega Beams, and may have a more unlimited amount of power base than Zeus, plus Tech
