@VeloZer0:It is not like the void is "inside of" X-Death or that Neo X-Death is the embodiement of the void itself, so no one can do that. I don't even know who should be able to do that because Bartz and the others were the only one who were able to destroy him during the final battle. Neo X-Death is just the true form of X-Death controlled by the void but just because the void controls him it doesn't mean those who are locked inside the void could take opportunity of that.
I'm not quite sure what this means. What I was asking was that even though some other villains might not have power on comparison to the void couldn't they follow through the plot that the heroes used to defeat Exdeath? Meaning that although he can use void powers on anyone wouldn't a strong enough villain just get sent to the Cleft of Dimension and have a chance to engage him directly from there?
