No, not asking for a Rumbles between these 3 entities.
I believe there are rules against making straight-up omnipotence vs omnipotence rumbles, yes?
And these are unquestionably the 3 most powerful entities (based on presentation) that DC ever published.
My question is simple: do any of these 3 have any usable on-panel Rumble feats at all? Or it is all talk and no action?
Oh, and Bonus Question: does Yin (The DC cosmic twin counterpart to Yang, the Marvel Cosmic who dwarfed the Living Tribunal) technically beat all 3, since he has actual on-panel feats from 1995's MARVEL VS DC?
