Powers and Abilities
The Ultimate Nullifier has been described as "the universe's most devastating weapon." As such, the Ultimate Nullifier has the ability to completely and utterly eliminate any target the wielder chooses (through violation of the law of conservation of mass), and—if the wielder's mind isn't powerful enough—the wielder himself. In the hands of a being with an extremely powerful intellect, such as Galactus, the Ultimate Nullifier can destroy entire time-lines from beginning to end and instantly nullify (and, paradoxically, recreate) a multiverse.
I know it's not official but on the official Marvel site isn't any article about the UN.
And by what's written there I doubt he could survive it, on the otherhand it could have been writen by an absoute Marvel Fanboy so I don't know...

Speak in diatonics, motivation diabolic
I'm like a religion, better locked in a box
Picture perfect image, more powerful every minute, baby
I am everything that you're not
