@Hellos: True, but my point is that Beyonder is a Cosmic Cube.
Some times. We can't really say what the Beyonder is since his origin keeps getting tossed around. He's gone from God / Super Omnipotent being, Cubed Being and now to Inhuman last I remember.
And it comes back to what Kubik said:
And Kubik is the one that owned the Beyonder in his own universe(almost actually destroying it before being talked out of it), he's pretty much stating that a nobody Celestial is infinitely more powerful than he is.
