One of the twelve Stages found within Injustice 2 is the Red Sun Prison. This is the place where all of the earth's worst offenders are held for their crimes against society, as it's a maximum security fortress that not even the best can think about breaking out of. One of the latest inmates is none other than Superman himself, the tyrannical murderer who is now being punished for his actions. This is Superman's home and dwelling place now; that is, until a new villain threatens all humanity.
