10 Most Powerful Weapons In Marvel History
6. All Black The Necrosword
Other than having the coolest name ever attributed to a weapon, All Black The Necrosword is also one of the deadliest weapons in the Marvel Universe... if you're a god.
The sword is capable of bonding with its user and killing any god in the Marvel Universe, but not only can it kill them, it feeds off their energy. Every time a god is slain by the sword, it becomes imbued with their energy making it even more powerful.
Over time, All Black The Necrosword was used to kill hundreds of gods making it so infinitely powerful, it's pretty much incomparable in the Marvel Universe. Of course, the sword does have a drawback. Anyone who uses it is corrupted by its power - warping their mind towards madness the longer they use it. Also, it needs to constantly slay gods or it runs out of power, but that's a minor weakness compared to other weapons.
It has an interesting origin, which was only recently revealed: All Black the Necrosword is the first symbiote in the Marvel Universe! All symbiotes that came after including Venom, Carnage, and all the whole Klyntar species came from that first blade forged to fight the Celestials by the God of the Symbiotes.
