In DC no idea.
In Marvel, assuming this is a regular Celestial, then imo we can begin from Galactus and work oure way up, also I'm taking into consideration that it says beat a Celestial not kill a Celestial, so far we only have two death of Celestials on Panel, One by Thanos W/HOTU and in a alternate reality where Earths population gathered itself into something resembling the Uni Mind and kills Arishem I believe it was. So only one actual kill in the mainstream 616 reality.

So we are speaking about all Celestials in all realities now? Or just the mainstream one because i figure were we going by the mainstream as usual....hmm so i can go in the Silver Surfer vs Superman thread and say KC Superman one shots Norrin? I think i will.
