The thing with Netero's Zero Hand is that I think it has a condiction on it tht requires him to use all his aura, so even on top of using all his aura I think it is powered up by the fact that he needs to use all his aura being a condition for it's use, as oppose to something like the Meruem rage blast which probably veries in aura output.
