Nonexistence is THE strongest omnipotent ability listed on this wikia, second only to Omnipotence. It's effects cannot be undone even by absolute wish if used at it's full power. In reality, there is no actual user of this power because it's just that OP. We just give the current known users, the benefit of doubt. Sure, they have have godly erasure abilities but none of them have displayed even half of the things listed in the capabilities. The only two being that actually come close are the Decreator and the Oblivion. Imagine the Abrahamic God concentrated and turned his Omnipotence into a single ability to erase all existence, the you'll get what Nonexistence is: 100% Omnipotence, concentrated in a single ability to erase all existence

Super Shenron is till date the best known user of absolute wish as it has actually been stated by the author and zeno himself to be able to grant all wishes and has feats to back it up as he restored countless universes back to existence effortlessly. But once again, Absolute wish is no match for Nonexistence, so obviously, super shenron cannot restore something that zeno erased using his full power.

I was fighting for zeno to be removed from Ultipotence because his power wasn't Ultipotence but Nonexistence. Nonexistence is "negative Omnipotence" and is completely subtractive in nature, it cannot create anything even indirectly. So, zeno can't have ultipotence. In fact none of the users listed have any godly manipulation techniques.
