10 Different Ways You Can Actually Defeat Galactus

9. Use The Ultimate Nullifier

The aforementioned device of ultimate nullification is Galactus' favourite object, and one that's indelibly linked to the character too.

Introduced along with the his first appearance in Fantastic Four #50, the Nullifier is used by Mister Fantastic to enforce Galactus' exile from Earth. The device itself is ridiculously powerful, allowing the user to eliminate anything they wish from existence at the touch of a button. It even has the potential to destroy entire timelines - entire realities - so you can see why everyone's favourite purple man isn't exactly fond of being threatened with it.

Given how there's a possibility that any user of the device could potentially erase their self from existence, however, it's probably a method to avoid. Although that hasn't stopped other, more powerful beings from using the device on occasion.
