Superman & Omni-Man Crossover Fanfiction
When the unknown force violates Earth's atmosphere, Superman goes to investigate and finds himself face to face with Omni-Man, a warrior from the Viltrumite Empire. Employed to conquer Earth, Omni-Man views Superman as a barrier to his goal, and Superman, always the defender, will not allow another planet to succumb to tyranny.
With their ideologies conflicted, a fight unlike any the world has ever known has been unleashed, one of will, power, and survival. But hidden behind their fists is a more profound question: Can a conqueror find redemption? And can Superman's belief in hope stand against an empire that has never fallen?
With Earth caught in the crossfire, the fate of humanity rests on a battle between two of the strongest beings in existence.
