Injustice 3: 7 Story Directions Fans Would Love

7. Superman Returns

In Batman's ending, Superman is de-powered and imprisoned in the Phantom Zone, while the remaining heroes form a new Justice League.

Bringing Superman back (after a Batman victory) would be rather pleasing, as Superman's villainous counterpart in the Injustice universe made for an excellent antagonist and a fresh take on the character, allowing the Injustice series to become what it is today.

However, this wouldn't be very original, as the story would end up being very similar to the last two games, yet if it can work twice, then it can probably work a third time.

The writers could even flip the first game's story on its head and have Superman (and his allies) filling the role of the resistance, while the new Justice League try to maintain the peace they worked so hard to establish.
