Guys with Infinite Gauntlet are not omnipotent.That is one of the writers mistakes.Word “omnipotent” is used too often in Marvel comics.
Omnipotent means that you can do absolutely anything whitout any limits to your powers(omni=all,potent=power).And Thanos couldnt defeat LT so that means he wasnt omnipotent.He thought that he was omnipotent until LT showed up.
Only ones who are omnipotent in Marvel are TOAA,PR Beyonder(was),Thanos with HOTU.
