10 Most Powerful Weapons In Marvel History
3. The Ultimate Nullifier
Galactus is one of the most feared entities in the universe thanks to his penchant for consuming the life force of planets. Since the universe was first created, Galactus has wandered from system to system destroying all life he finds. He is a force of nature and has been revealed to be a necessary force in the universe, but that doesn't mean he isn't completely feared.
When he first appeared on Earth back in Fantastic Four #48-50, he was presented as an unstoppable force. The only way to defeat him was to use a weapon of his own creation, the Ultimate Nullifier, which was kept within his mighty vessel.
With the help of the Silver Surfer - Galactus' herald - Johnny Storm was able to retrieve the weapon. Reed Richards then threatened Galactus with it, which resulted in him agreeing to leave Earth alone and leave.
The Ultimate Nullifier's abilities are pretty simple: it nullifies any target from existence. This pretty much means that whatever you point your mind to while wielding it will cease to exist. A stray thought will result in the user's obliteration as well so it's not something that should be used lightly.
