Glactus onslaught and grand master vs dc comics?

You should be a little more exact in this one. Are you suggesting three people vs every super powered being in the entire DC Universe? That's a bit of overkill don't you think? DC does have it's fair share of cosmic beings as well. Take Onslaught as an example, yes he gave quite a few Marvel characters a run for their money, but there are many DC characters that could take Onslaught one on one, such as Superman, Doomsday or Darkseid. I'll have to pick DC as the winners.
