and you never even added the tough guys!
as far as exodus - wasn't he ko'd by . . . BLACK KNIGHT WITH HIS 'NEURO-SWORD'!? i know he has the gem here, but that might make it even WORSE for him because as his power increases his control DECREASES! he sets limits on himself because if he pushes too far he'll go insane, or explode or something equally unpleasant.
so let's see . . .
aquaman (who is very close to manhunter, perhaps greater, time will tell) and manhunter occupy exodus and wonderwoman lasso's him. exodus done.
5 gl's take thanos. if you don't think so throw in cm and black adam and superman. OVERKILL.
sentinels of magic (with fate and stranger) could probably handle molecule man. if not, throw in any of suprem's extras.
demogorge is likely less a problem than mm - he's just above elder gods and so likely below mm. i'm thinking the swamp thing could give him a run 1on1. and if you scoff at that, you really have no idea what the swamp thing is so read him first. if you still don't think he'll be enough, throw in the other dc elementals - firestorm (true form), red tornado and naiad. think i'm missing one . . . and maybe throw in blue devil from the sentinels - i wonder how demo would like the taste of the trident of lucifer . . .?
i've also left out 100's of other powerful dc characters. mm and demogorge are the only real threats and dc has enough - more than enough - to handle these 2.
