The Marvel Universe is home to a lot of weird, interesting, and impressive gadgets and weapons. The most powerful weapons of Marvel are seldom seen, mostly because they’re so omnipotent it becomes difficult for writers to work around their destructive abilities.
For example, if Thor is truly in possession of an all-powerful Necrosword capable of taking down Galactus, then why doesn’t he use it all of the time? This is why we see a lot of tame weapons in the Marvel Universe. Many of these weapons are only used in desperate times against the biggest baddies, and the rarity of these weapons from Marvel comics only adds to their intrigue.
There is quite a history of legendary character weapons in comic books, and Marvel is no exception. Not all of the uber-destructive items present in the Marvel Universe are tied to one character in particular, but many are. Marvel has a bevy of well-armed, superpowered individuals ready to show just how mighty their weapons can be.
What It Is: The Infinity Gauntlet is probably the most famous glove in the history of fiction, and it’s the all-powerful item at the center of the Marvel Cinematic Universe. The Gauntlet is actually more like six weapons, as it’s merely a conduit through which the powers of the six Infinity Stones can be channelled and amplified. Thanos is the most notable wielder of the Infinity Gauntlet, but not the only one!
What It Does: The Infinity Gauntlet essentially makes its wearer omnipotent, so there’s very little it cannot do. Thanos has used it to slap around cosmic deities, and in the actual Infinity Gauntlet he used the device to absolutely annihilate the entirety of Marvel’s roster of superheroes.
What It Is: The Odinsword is a storied aspect of Asgardian history. Originally, it was a ridiculously oversized sword said to end the universe if were ever unsheathed. Eventually, the blade was shrunk down to massive-but-wieldable size, and Odin gave it to his son, Thor.
What It Does: Little is known of the destructive power of the Odinsword because it has rarely been used. However, both Odin and Thor think of it as more powerful than Mjolnir, Thor’s hammer. Thor is able to use the Odinsword to slay Cul, the brother of Odin, who is said to be just as strong as the Allfather.
What It Is: The Ultimate Nullifier is the first of many ridiculously strong items to show up in the Marvel Universe. The Watcher gave it to the Fantastic Four so they could use it to scare Galactus away from Earth. The Nullifier has since been used mainly as the ultimate threat, and it usually works, despite its nondescript appearance.
What It Does: The Ultimate Nullifier’s abilities are ill-defined, but it can basically annihilate anything at which it is pointed. It is also quite difficult to control, and it has a nasty habit of nullifying its wielder along with its target. In the hands of someone with sufficient power, the Ultimate Nullifier is said to be able to destroy entire universes.
All-Black The Necrosword
What It Is: All-Black the Necrosword has a seriously heavy metal name, which is suitable, given it's the signature weapon of Gorr the God Butcher. Gorr is a recent addition to Thor’s rogues’ gallery, but he was a memorable one; he went on a campaign of god-killing across the universe, using his Necrosword to masterful effect.
What It Does: The Necrosword is capable of killing some of the most powerful beings in the Marvel Universe - the gods. In fact, it gets stronger with each god it kills. In one story depicting the far-flung future of Earth, an elderly Thor used All-Black to slay Galactus, proving the Necrosword is one of the deadliest weapons in existence.
