The game Injustice 2 offered players a choice of  two endings , depending upon their choices.  The first ending, known as  "Absolute Justice" ends with Superman being depowered by Gold Kryptonite and banished to The Phantom Zone. The second ending, "Absolute Power" ends with Superman reclaiming control of the Earth, after stealing the powers of the alien artificial intelligence Brainiac.

Batman Enslaved By Superman In Injustce Vs. Masters Of The Universe

Injustice Vs. Masters of The Universe is set in the Absolute Power reality, and we see that Superman is using his newfound technological powers to further cement his grip on the Earth. With Wonder Woman as his most trusted lieutenant and a mind-controlled Bruce Wayne acting as his battlefield strategist, there is little the free heroes remaining can do to fight back. Since magic is one of the few things still capable of hurting Superman in his current state and they need an unknown quantity that Batman is unaware of, this leads to The Insurgency's journey to the magical world of Eternia and their seeking out He-Man to act as their champion.

Naturally, He-Man is willing to answer the call to justice and is ready to leave for Earth after making arrangements for some of the Insurgency to remain on Eternia to help protect his world while he is away. He will not be going to the Earth of Injustice alone, however, as the warrior woman Teela and wizard Orko will also be traveling to Earth.

And a good thing too, because Superman has recruited a face familiar to Masters of the Universe fans to aid him in the battle to come.
