10 Most Powerful Swords In Comics History

1. All-Black The Necrosword

What happens when you combine most of the powers of the swords on this list and put them all in one single blade? You get All-Black the Necrosword. It may have a pretentious name, but this sword is probably one of the most powerful objects in the Marvel Universe.

A black shapeshifting blade that can even create semi-sentient beings, the Necrosword can kill anything from suns, planets to the entire universe, but its main purpose is to kill god-like beings. That’s exactly what Knull, the God of Symbiotes, forged it for after being disturbed by the first lights of Creation.

The moment he made it out of living darkness, Knull used All-Black to decapitate a Celestial (no small feat).

However, what truly makes the Necrosword such a dangerous blade is the fact that it can turn anyone, even a skinny mortal alien like Gorr, into a cosmic level killing machine. The God Butcher may be its most famous wielder, but All-Black has also been in the possession of Galactus, Ego, Loki and Thor, who had the weapon purged from himself since it could drive him mad.
