I don't care about "Oh, well he could beat Darkseid" or any Living Tribunal vs. stuff. I just want to know his feats.

One comes to mind, when Adam Warlock annihilated the cosmic abstracts during his time as the holder of the Infinity Gauntlet, that the LT just simply snapped his fingers and all the abstracts were brought back again.

Oh and he held the Phoenix Force in his palm.

Understandably though he doesn't have many on-panel feats because of how omnipotently powerful he is (or supposed to be) over just about everyone.

Also I want to know his feats, because he can beat only infity gaunlet, that is only universal, however he was beaten by Protege, who is just universal, bah I don't know, however many fans believe in many things that never happen in the comics, so only superior than infity gaunlet or what ?

One of his feats is winning a race against a snail.
