So people who love Marvel are now saying that it doesn’t mean anything, that it’s just bad writting. And yet, they were the ones saying the Presence isn’t omnipotent because he said he was created by external forces...
You guys are funny.
That was never true though, just people taking a scan from Lucifer comic book out of context. The external forces referred to Sandman comic book, where the origin of humanity was explained. The Presence didn't initially exist, humans used Dream of the Endless to dream The Presence into existence. The whole of reality was rewritten like it never existed before and The Presence was the creator of everything, the Omnipotent being.
That being said, The Presence gave away his Omnipotence to Elaine Belloc over 10 real-life years ago. So I am not sure why people are still arguing for the Presence. Lucifer's solo comic book established that Elaine Belloc took over as the Omnipotent God.
Did Zolomon achieve phasing in the Flash War because he sure as hell didn't have the ability phase in Post-Crisis.
In Post-Crisis he was an extremely overrated speedster brick with no real abilities, he wasn't even able to knock out Wonder Woman. Also the Wonder Woman "hits harder than Superman" is an PIS outlier statement, since Superman has literally punched her harder.
At this point, Mr. Mxy stated that by going into this dimension, not even he would survive what is on the other side, never was it stated that he could not make the leap as well, he was just that scared of losing his life or being trapped for eternity. And Superman just went through it and survived even while having lesser hax than Mr. Mxy.
Mxy never stated that he would die there or he is afraid to go there nowhere in that scan. Did you actually read the actual issue? Mxy put the rocket into that Dimension that Superman went after.
