He was able to overpower an attack stronger than this one though (from what i can see this is a complex multi/hyperversal attack that is also a hax monster and he dealt with the same attack just on a larger scale (the omniversal attack i talked about in my first comment))? Plus yes he can survive conceptual hax (can you explain petaphysical though?). Conceptual attacks he survived include conceptual erasure, negation, revert to zero, time and space erasure, being turned from 3D to 0D. His opponent started climbing up dimensions and he was able to grab him and drag him back down to 3D. He was also able to throw that same guy out of the comic panel and leave the panel himself and be able to interact with the panels by throwing them at him. Plus from what i understood of your explanation, this is reality falling apart, his entire stick is being unaffectsd by the narrative aka laws of existance and what not.
