The-One-Above-All is only omnipotent being in Marvel Universe, so he cannot be beaten by them (Its one and only wielder is able to defeat the combined might of all Creation and its mightiest beings just by wanting it, without the slightest effort). And about Pre-Retcon Beyonder- he was Omnipotent, because there wasn't any One-Above-All (by authors) in Pre-Retcon. After creation of One-Above-All, Beyonder's power was decreased by authors, to allowe One-Above-All being Omnipotent. So, in fictional reality, One-Above-All is creator of Marvel Universe, he was allways Omnipotent and unbeatable. It's just wrong done by authors.
