Accept Exitar because in the Marvel books it says Kubiks powers were nomatch for Exitar. "Kubik's power was capable of creating at least a duplicate of Earth (and its people) and the sun from the matter in a pocket dimension. Hence, Kubik may be more powerful than beings such as Odin, Zeus and the Watcher, who have not been shown to be capable of such feats. How his power compares to that of Galactus is unknown. However, Kubik may be less powerful than most known Celestials, and is definitely less powerful than the gigantic Celestial Exitar"
