I don't know if you peoples read the funny papers, but Grant Morrison's Final Crisis is imo really shaping up around a question that resonates with PS:
How do you fight gods?
These gods can fire weapons through time, make slaves using the Anti-Life Equation (think Last Word but negating Freedom instead of Life), but that isn't the worst of it. The gods are not simply supervillains, but rather manifestations of the darker emotions within mankind. Though similar to the planar lords, they can reach into reality so that a calculating person channels Athena and one filled with murderous anger channels Ares.
It reminds me of Quethel's fight with the Evil "elemental" in Book I of SpiderQueen War (the only good one in the series really) where as horrible as the drow are the raw essence of Chaotic Evil traveling on the thought-plane cracks their minds open. How do fight something that IS anger, or even IS love?
Somewhere out there, is a sword for just that occasion.
