Taking place after the Outworld queen has taken over Outworld. Mixing in elements of Mortal Kombat vs DC and Superman Vs Aliens.
After the events of DC vs Mortal Kombat, Superman vs aliens, and Mortal Kombat X.
The sovereign ruler of the Xenomorph empire came to learn of the events on Outworld. Of one reality where they met superheroes and villains of earth. Another where xenomorph now ruled Outworld and she learn of Superman and Batman coming across her species. Even with Superman being impregnated with an alien embryo. Were it not for him being close to the sun by the time the alien was to be born, the chestburster would've ripped through Superman's chest and killed him. Possibly
Becoming the most dangerous xenomorph in existence with Kryptonian abilities. This made the Empress of the Xenomorph race, want to create an Apex Xenomorph and she would augment herself as well.
She took DNA from the preserved frozen body of Frost, DNA from a shokan, tarkatan, and Reptile. Injecting into her own body and use genetic manipulation, the gene splicing gave her the abilities from each of those species.
She would lure the very same Superman who survived the first alien impregnation, to a world where she could ambush him. Attacking a colony on a random planet she had picked. Superman was lured there where she converted the planet's atmosphere with Kryptonite dust to weaken Superman and also using artificial red sunlight to drain his power. She personally impregnated Superman using a special black queen facehugger that gave birth to three aliens, one drone, one warrior, and one queen. She would consume the drone in order to obtain the Kryptonian DNA and abilities. The Kryptonian Xenomorph would act as the bodyguard to the Kryptonian Xenomorph queen.
The new queen would have the sole purpose of creating new aliens with Kryptonian DNA already a part of their genetic makeup. She herself would feed on Superman' body and turned off the red sunlight generators and turn on the artificial solar radiation machines. Thanks to Kryptonite already being in Superman's system. Both herself and her children were able to adapt to it and overcome the weakness to it. The yellow sunlight would empower them both and just like she had hope. Her two new children and herself, now had Kryptonian abilities.
The empress didn't stop there though. Between herself and her two special new children, she sought out the one other alien species that would help in her war with the machines and to help evolve her species to the pinacle of evolution.
Her gaze was now on the Martian Manhunter. Thanks to the Martians weakness to fire. Creating a trap for the green Martian was not nearly as hard as it was for Superman.
Using superior numbers, new Kryptonian powers, Outworld sorcery and science. Lucretia Talbot captured John Jones and let another special queen facehugger attach itself to him. Like with Superman, the Martian Manhunter gave birth to triplets. Just like before, the Empress cannibalized the drone but let the warrior and queen live. She now has gain access to Martian DNA and their powers. She had a new queen who could produce even deadlier alien breeds thanks to shapeshifting ability of the Martians.
Her two special queens would play a pivotal role in galactic survival and her ascension to supreme ruler of her species. All that was left was to create one very special child to serve as her elite warrior, her Apex Predator. Capturing a white Martian next, she personally impregnated the Martian directly herself. Combining the DNA from a shokan, Tarkatan, Cryomancer, and Zatarren; with Kryptonian & Martian DNA,, she was able to create her ultimate offspring.
The Apex Xenomorph XXX 121,with abilities from several races from Outworld, and two of the most powerful humanoid alien species ever known, Kryptonian and Martian.
Her new child would become the most dangerous Xenomorph, the universe has ever known, beside herself of course.
