10 Most Powerful Weapons In Marvel History
4. The Cosmic Cube
If you've only seen the movies, you might think the Cosmic Cube is what is known as the Tesseract, but long before that blue cube showed up on screen, Marvel introduces a powerful weapon called the Cosmic Cube in the pages of its comics.
Cosmic Cubes were the go-to weapon of choice for Thanos before the Infinity Gauntlet was created. It's one of those cosmic artifacts Thanos will stop at nothing from acquiring due to its incredible power, which allows the person wielding it to reshape the universe's reality at a whim.
The Cosmic Cube is essentially a "Wish Machine" enabling whoever holds it to reshape reality however they see fit. Literally anything they can imagine will happen as a result of the Cube's power.
Using a Cosmic Cube is incredibly dangerous for the wielder and anyone nearby... like on the same planet. It requires concentration most couldn't possibly achieve and a random thought during operation could result in the destruction of whatever planet you might happen to be standing on at the time.
