The Quantum Worm

The Quantum Worm is a giant multi-dimensional being that dwells in the outer reaches of the galaxy.

Appearance
It's a giant fucking worm what more do you need to know?

Behavior
The Quantum Worm burrows from galaxy to galaxy and dimension to dimension by literally eating the fabric of space time, creating wormholes that allow it to move long distances in seconds. These holes quickly fill behind the worm, trapping anyone who entered them in that dimension. The Worm itself shows no sign of higher intelligence and seems to just be a worm. It is not malicious in its behavior and simply exists to feed on the fabric of time and space. That being said, it has been reported by some deep space truckers that the worm has devoured entire planets before, though whether on purpose or by accident can be debated.

Trivia

 * Despite not being from Uranus, the Quantum Worm is considered a cryptid.
