While a comedy-centric antagonist Edifice Rex would prove to be a threat that made many of Marvel's cosmic entities extremely concerned (save for Master Order) due to his insane decision to "clean" the universe via reverting everything back to the way it was prior to the Big Bang, effectively trapping all of reality inside a Cosmic Egg.
Powers / Abilities
Edifice Rex has immense cosmic power on a par with Eternity, he is sufficiently advanced that even Galactus and a good number of other Marvel cosmic entities are wary of him.
He is, however, vastly below the power of a being such as Beyonder (prior to Beyonder's retcon).
- he shares some similiarities to Beyonder in being well-intentioned but feared nonetheless due to his unique power (however original Beyonder far surpassed him in power and was taken much more seriously)
