One Push-Men

wo super-humans are duking it out in a post-apocalyptic world. But there is one problem. There are not able to kill each other. Even though their powers are able to destroy solid stone walls and tear mere mortals into pieces within a fraction of a second, when faced against each other, these powers are reduced to simple pushes.

So they continue to fight while the world around them falls apart, both of them yearning for the day they will finally be able to rest. Till then they will just continue to push each other into lava.
