Fan Casting Superman (Earth-49) in Injustice: Brightburn

Throughout the film's final battle, we see this variant of Superman, plus his version of The Regime Council take on the Earth-1610 Regime, decimating over more than half it's numbers and leaving both Gotham and Arkham City in ruins. However, after he is attacked more than enough times with all forms of Kryptonite, and the realization that some pf his own forces are dying in battle, Kal-El calls off the attacks on both cities, retreating into a portal back into his home universe conjured by Raven.
