Cube Being is a term originating in Marvel Comics, used to describe a Cosmic Cube which has gained sentience. While that is the most strict definition, it can also be applied to other beings from Marvel or other fiction with a similar level of power. A Cube Being is above Skyfathers but below Celestials.
General characteristics of the power of a Cube Being are:
- Universal - level reality warping (complete control of one universe, usually including the ability to destroy/reset it)
- Some multiversal abilities (ability to manipulate extra dimensions and have their influence felt across the multiverse. Not actual multiverse level reality warpers or busters).
Examples of actual Cube Beings in Marvel:
- Kubik
- Kosmos
- The Shaper of Worlds
- Post - Retcon Beyonder
- Post - Retcon Molecule Man
