This page covers the Marvel comicbook object Ultimate Nullifier . If this is not the page you were looking for check here.
The Ultimate Nullifier appears as a small hand-held silvery-metallic device with little or no apparent functionality, though it is possible that like Galactus, it appears differently depending on who is observing it.
The Ultimate Nullifier is capable of destroying any target the bearer directs the Nullifier at, if the bearer lacks the proper control, concentration, or power; the Nullifier will destroy the bearer as well and possibly the universe itself. While the origins of the Nullifier are largely unknown, it had been revealed that the Ultimate Nullifier is an aspect of Galactus himself. It is the only known object known to inspire fear in Galactus.
It was first given to Reed Richards by the Watcher when Galactus first appeared to devour earth. Reed threatened to use it against Galactus which Galactus became frightened so he left earth never to try to eat it again unless he was really hungry.
It later appeared during the Infinity War when Galactus had left Thanos and a number of Earth’s heroes aboard his starship as Galactus to plead his case on behalf of Adam Warlock to allow the Infinity Gems to function as one. As soon as he left the Magus appeared and kidnapped Warlock. Leaving Thanos with little in the way of options inquired about the Ultimate Nullifier’s location of Susan Storm. Nervously she betrayed it’s location with a look. Thanos picked it up and offered it to Quasar, saying that only a man as resolved and self-sacrificing as Quasar should fire the weapon at the Magus.
When Quasar arrives in the Magus’ dimension he is (unbeknownst to him) blanketed with an energy dampening field which disrupted the Nullifier, but not the Quantum-bands. When the controls of the dampening field were later damaged by Dr. Doom and Kang the Conqueror, Quasar was able to activate and slowly build power in the Nullifier, only to have it devastating effect turned against him by the Magus wielding an incomplete Infinity Gauntlet that was empowered by the Living Tribunal.
Later, Abraxas, the embodiment of destruction attempted to destroy Galactus with the Nullifier, but Galactus demonstrated an ability to effortlessly call the Nullifier to his person.
During the JLA/Avengers crossover, the Ultimate Nullifier was one of twelve items of power (six from the Marvel Universe, six from the DC Universe) that were scattered about the two parallel Earths. When the Nullifier was found by the JLA, the Martian Manhunter was nearly overwhelmed by the power of the Nullifier as he merely examined it.
