10 Most Powerful Weapons In Marvel History
1. The Heart Of The Universe
It's easy to imagine the fully-assembled Infinity Gauntlet as being the most powerful weapon in the Marvel Universe, but there is one device more powerful: the Heart of the Universe.
The capabilities of the Heart of the Universe are unlimited. Whoever possesses it becomes the supreme being of the Marvel Universe. Nobody and nothing else matters compared to whoever wields it.
The Heart of the Universe was created by Marvel's Supreme Being to fix a problem related to the imbalance of the Universe's architecture. It was meant to balance the forces of good and evil after the levels of "good" began to give way to an increase in "evil" throughout the cosmos.
It was, at one time, possessed by Thanos who remarked that possessing the Infinity Gauntlet paled in comparison to the vast amounts of power he held in his hand. When the abstracts of the Marvel Universe, which includes the Living Tribunal and many others attempted to take it from Thanos, he easily defeated them all. Eventually, Thanos remakes the Marvel Universe as it once was, but leaves the Heart out of it, which means it no longer remains in the canon of the Marvel Universe.
