who can beat the First Firmament

He is the first probably omniversal being besides T.O.A.A,in the marvel universe.(now I didn`t get to read every issue in the new arc about him so sorry if I am mistaken).But i have already read a bio that his power trumps Living Tribunal`s,this is the 8th interation of the marvel universe,so he has had from the very beigining to build power.does Beyonder,Owen one on one or a whole team of high end reality bending,cosmics have a chance against him.Someone or someway he was beaten if anyone could clue me in before I start actually find the info would be great.

We don't know much other then the first Firmament being the 1st thing in terms of TOAA Creation......The comic says he is a Universe but then goes out to show he has Omniverse level power but the Eternities we have seen are all Omniverses all from the 1st to the 8th Omniverse.

The Living Tribunal was PIS to lose due to his hierarchy rank but to answer the post.....anyone who is Omniverse level could beat him easily.
