Superman's fight(s) with Brainiac & Doomsday Ruptured The Phantom Zone 2, When He and Phantom Stranger Fought Superman managed break through Both Physical and Metaphysical aspects of P.S. (Phantom Stranger scale's to beings such as Blight, Spectre, Trigon (and His Son's IIRC) etc), Superman also punched God Brainiac so hard it rippled through out the Multiverse who was God Brainiac was MASSIVELY Multiversal (You could Argue above according to some) and before You say "Well... The only reason why that happened was because those version's of Brainiac were all connected to one another" Welp, Black Adam also did the same but it didn't ripple through the Multiverse Here, Superman also broke Broke through his energy shield's and tanked multiple blasts from him, Superman was also capable of destroying Galactic Golem who was a living Universe AT THAT TIME (No! He wasn't a Galaxy and never was in fact), Superman is a Threat to existence according to the Prophecy Wall Here (this is a HUGE Feat if You know context such as how big a single DC Universe is)... Are those good enough?
