"One of the maddening but beautiful things about comics is that you have to give characters a sense of change without changing them so much that they violate the essence of who they are." ~ Ann Nocenti, Chris Claremont's X-Men.
I'm going with general impressions of the characters since I'm not sure about the most recent versions. Superman and Black Adam should be a draw assuming pure boxing match.
Unless Aquaman has gotten an insane powerup, Wonder Woman is just too much faster, stronger and more durable.
Maybe I'm wrong but I don't recall Grundy having super speed so the Martian Manhunter should win here.
If Lobo still has his crazy regenerative powers, he should win.
Power with Girl is better.
Supes probably has more basic combat skill than Black Adam.
Wonder Woman is way stronger and more skilled than Arthur.
J’onn is probably more technical than Grundy (assuming one of the Class 100 versions of Grundy rather than one of the Batman-fighting ones) and probably better base durability. He might win on points.
Kilowog has no business fighting Class 100s in pure H2H, Marquess of Queensberry Rules or otherwise.
