PC DS certainly does not solo. I'm curious Omega as you're more versed in DS than I, even though I have read a fair share of DS to be sure. Can you please name for me all the people DS beat one v one with no outside help or amp that are Thanos/Zeus level
PC DS didn't generally fight people one on one except maybe PC Orion. He fought teams.
From his throne in Apokolips he defeated the PC JLA (and I think JSA as well) with little more than a gesture. When he was "dead" and trapped in the Source Wall a fragment of his spirit manifested in Earth II and created a construct in his likeness that easily bested and subjugated the Injustice Society.
PC Mantis was someone who unamped could compete on even terms with Superman and the like. After draining Hal Jordan's power and getting a big amp as a result he confronted Darkseid and hit DS with his best shot. DS was unfazed and laughed the attack off. Mantis wisely re-pledged his allegiance to DS forthwith.
Then there's the Great Darkness Saga which showed that even after draining Mordru, Time Trapper, and a bunch of artifacts he still wasn't at full power.

As nice as those implication of power are, and the good showing again the JLA. I'm still not getting where this notion that PC DS was somehow above Skyfather level, when he's never beaten a skyfather one v one. Which is why i asked, because I couldn't recall an instance where he had. Thus to think (as some have claimed) that DS could solo two skyfathers (one low/mid and one high) doesn't make a bit of sense to me.
