DC's Ultimate Nullifier

Is there a weapon in DC that is considered the strongest weapon ever like how Marvel has the Ultimate Nullifier?

Phantom Zon generator? IDK.

The Life Equation and/or/slash The Alpha Effect? Although it has a direct opposite, I don't think there's much that can stand against it otherwise?

I think Mister Miracle still has the Alpha Effect.

The Chew Force.

The Infinity Gauntlet is stronger than the UN

Warlogog ,Dreamstone ,genisis box , antilife equation etc

Maricle machine

The Miracle Machine

Definitely the miracle machine. Its tech that can basically wipe anything out of existence including possibly it's own timeline... just like the ultimate nullifier.
