Summary
Phillip Kennedy Johnson’s series-spanning Olgrun saga has shaken up DC lore in a big way, with cosmic repercussions for bothGreen LanternandSupermanalike. With more and more fragments of the dead god continuing to filter into DC continuity, conflict between these two titans increasingly seems to be inevitable.
InGreen Lantern: War Journal#12 - the final issue of Phillip Kennedy Johnson and Montos’monumental John Stewart series- John faces down his nemesis, the Revenant Queen. Here, the Queen drops a bombshell, claiming thatJohn Stewart has been chosen as Olgrun’s reincarnationfrom time immemorial.

“Your fate is inevitable, John Stewart. Olgrun chose you as his vessel before your earth was formed,” she boasts. If this is the case, it implies thatanyone who holds an aspect of Olgrun’s power will inevitably come into conflict with John Stewartshould Olgrun manifest through him.

Green Lantern and Superman Seem Destined to Fight Over Olgrun’s Power
Continuing the Story Established inSuperman: The Warworld Sagaby Johnson, Daniel Sampere, and Riccardo Federici
According to Olgrun’s lore, the mad god was split into seven different parts to prevent him from destroying all existence.Green Lantern: War Journal#12 culminates withJohn Stewart receiving control over Olgrun’s Ring, granting him command over all of Olgrun’s forces. However, the first aspect of Olgrun (the Fire of Olgrun) was bestowed upon Superman’s adopted son, Osul-Ra, inSuperman: Warworld Apocalypse#1.Also taking the form of a sword, the Fire of Olgrun is a font of incredible power, thereby making Osul-Ra one of the most dangerous entities in the multiverse - guarded by Superman himself.
See how Osul-Ra receives the Fire of Olgrun inSuperman: Warworld Apocalypse#1 by Phillip Kennedy Johnson, Will Conrad, Brandon Peterson, Miguel Mendonca, Max Raynor, Lee Loughridge, and Dave Sharpe.

A clash between these two inheritors of Olgrun would be devastating. John Stewart has already attained functional godhood as ofGreen Lantern#12 and is one of the most skilled Green Lanterns to ever exist.Superman’s powers have likewise been off the chartssince his absorption of Genesis energy at the end ofWarworld Saga, once admitting to Lex Luthor that “concepts like weight, distance, temperature, even spacetime have largely lost their meaning for me.“A fight between John Stewart and Superman would mean a conflict of powers on a magnitude usually reserved for Crisis-level events.
Follow John Stewart’s ascent to godhood inGreen Lantern#12 by Geoffrey Thorne, Tom Raney, Marco Santucci, Michael Atiyeh, and Rob Leigh. Meanwhile, Superman’s full might is revealed inAction Comics#1050 by Phillip Kennedy Johnson, Tom Taylor, Joshua Williamson, Clayton Henry, Mike Perkins, Nick Dragotta, Alex Sinclair, Frank Martin, and Dave Sharpe.

Superman vs. Green Lantern Would Be A Fight Of Multiversal Proportions
Two of Olgrun’s aspects have emerged into DC continuity, but crucially, if John Stewart is Olgrun’s chosen vessel, then Stewart either needs to gather these aspects or they need to come to him in order for Olgrun to be whole. This means that for Olgrun to be whole, John Stewart would need to claim the Fire of Olgrun from Osul-Ra, which Superman would never allow. Yet as Olgrun’s fractured pieces continue to reveal themselves, the mad god’s return feels slow yet inevitable - and with it, the ultimate battle betweenGreen LanternandSuperman.
