Question

Sorry if this is in the wrong place, it's been a long time...is there a consensus most powerful being in the Marvel Universe?

Holy crap! It's Fourpower. Good to see you. I believe the most powerful in MU is One-Above-All. If you aren't counting cosmic beings, than no.

You too...it's been a while. This site is almost unrecognizable now! (in a good way, I mean)...Very cool the way it's grown.  
  
 That's interesting...I was thinking maybe the Living Tribunal or Galactus or somebody, but I figured someone here would know. 
 
What about DC?

I would say Living Tribunal is probably second(he is the right hand man to One-Above-All). One-Above-All is supposed to be THE God of the Marvel Multiverse. He exists in all their various universes. Some say he is just Stan Lee.
 
As for DC, I believe they have a counterpart to the One-Above-All they call The Presence. It believe it's basically the same concept as Marvel's.
