As regular Xenomorphs in Alien stories tend to get too mainstream, gene splicing is sometimes introduced to create new breeds of often ridiculous Xenomorphs. These new Aliens vary in size and appearance, but still inherit their traits from their hosts. Here is a list of different breeds of Xenomorph hybrids, some born from exotic hosts and others mutated through experimental gene splicing.

White Hybrid Xenomorph

A White Hybrid Xenomorph from Aliens vs. Predator: Deadliest of the Species

The white hybrids were a new race of creatures created by the rogue AI named Toy in the Aliens vs. Predator: Deadliest of the Species comic series. They inherited the traits of both Xenomorphs, Yautja and humans, but mostly looked like Xenomorphs with white skin. They had acid for blood and still used facehuggers for reproduction. However, they were more intelligent than regular Xenomorphs, some even being able to speak. Their leader was the White Hybrid King, and the hybrids fought against Big Mama Predator and her allies.

Newborn

The Newborn with Ripley 8 in Alien: Resurrection

The Newborn was a unique type of Xenomorph only seen in Alien: Resurrection and its related media. It was born from the womb of the Auriga Queen, the cloned Xenomorph extracted from the chest of Ripley 8. The Newborn was huge from the start and was possibly still growing at the end of the movie. Its white skin supports that theory, as chestbursters usually shed their light skin before adulthood. The Newborn expressed great physical strength, but also affection for its presumed mother - Ripley 8. Later Marvel stories such as Alien: Icarus explored a darker version of the same idea when the human colonist Lee became a Xenomorph hybrid who could command Drones without a Queen. This abnormal Xenomorph never reached adulthood as it was killed by Ripley 8 by sucking it out of the hull of the Betty.

Offspring

The Offspring from Alien: Romulus

The Offspring, while not a direct Xenomorph, was a unique human/Engineer/Alien hybrid introduced in Alien: Romulus. Resembling the Newborn from Alien: Resurrection, it developed from a pregnant human woman who knowingly infected herself with the Black Goo Pathogen, hoping to heal her wounds. Initially, the Offspring resembled a human infant within an egg, but it quickly grew into a pale, humanoid form with features similar to an Engineer. In its final transformation, the Offspring began to develop a tail, inner mouth, and dorsal tubes. Rain Carradine ultimately defeated it aboard the Corbelan IV by ejecting its cargo compartment into space.

Bug Men

The Bug Men from Aliens: Colonial Marines

The Bug Men were one of the most humanoid Xenomorph hybrids that could talk and carry weapons. They were the result of experimentation with Royal Jelly by Dr. Ernst Kleist, who also famously created the Rogue Alien. The Bug Men were used to further the crazy goals of the mad doctor, kidnapping humans for further experiments and fighting alongside the Xenomorphs. This terrorist cult was featured in the Aliens: Colonial Marines comic book, and were wiped out together with the Colonial Marines squad at the end of the story, when a space station exploded.

Killer Croc Xenomorph

The Killer Croc Xenomorph from Batman vs. Aliens II

The Killer Croc Alien was born in Gotham City as a result of experimentation on Batman villains by Dr. Fortune. In Batman/Aliens II, she took DNA from prisoners in Arkham Asylum and spliced it with Xenomorph biomatter, trying to create a small army of supersoldiers. While the Two-Face and Joker Xenomorph were more human-like and easier to control, the Killer Croc Alien was a bad beast that turned against Dr. Fortune and bit her head off. Batman took down the monstrosity using his power armor, having experience with fighting crocodile Aliens before in the first Batman/Aliens series.

Alien-Terminator Hybrid

The Alien-Terminator Hybrids from Aliens versus Predator versus The Terminator

The Newborn from the USM Auriga wasn't the only Xenomorph hybrid that Ripley 8 had to fight. Soon after the events of Alien: Resurrection as seen in the Aliens versus Predator versus The Terminator comic, Ripley 8 encountered Terminators and found out about a plan to create an army of Alien-Terminator hybrids on a secret base on an asteroid. She joined a clan of militant Yautja who performed the blooding ritual on her, an honor only bestowed on a small group of people. Together they destroyed the Alien-Terminator hybrids by using the help of Xenomorph acid, which was the main weakness and oversight by Skynet of the otherwise indestructible creatures.

DarkAlien

The DarkAlien was the hybrid in Witchblade/Aliens/Darkness/Predator: Mindhunter. On the escape shuttle from Kenneth Irons' ship, an Alien took on the Darkness, the power carried by Jackie Estacado. It kept an Alien's strength and aggression, and torn tissue closed again the way Jackie's Darklings rebuilt themselves. Sara Pezzini and the hunter Sister Midnight destroyed it through the Witchblade before the automated shuttle could reach Earth.

Parademon Xenomorphs

Adult Xenomorphs that hatched from the infected Parademons swarming down on Big Barda and the warriors of New Genesis in Superman vs. Aliens II: God War

The Parademon Xenomorphs came out of Superman vs. Aliens II: God War, after Darkseid found Xenomorph eggs aboard an ancient craft that crashed on Apokolips and had his own Parademons infested with the creatures. When the infected army came through a Boom Tube to attack New Genesis, thousands of Chestbursters erupted from the Parademons at once, and Superman warned that Darkseid meant to plant a colony there. At the end of the story, Darkseid showed Desaad rows of tanks holding Parademon-Xenomorph hybrids, a secondary tactic he kept in reserve in case Orion stayed loyal to New Genesis, and a dark echo of the DNA reflex that lets the creatures take on traits from their hosts.

Vampiric Queen

The Vampiric Queen grew from the Chestburster that tore out of Vampirella's chest in Aliens/Vampirella, after a Facehugger caught her in the Nosferatu catacombs under Mars Colony One. It tunneled up into the colony's greenhouse, killed a colonist there, and grew into a Queen with bat-like wings like those of its host. She laid her eggs among the greenhouse trees, impaled the colonist Lars with her tail, and flew after the last survivors as they escaped in the short-range M9-B craft. She clung to the craft until the awakened Nosferatu, in giant bat form, dragged her away toward the surface of Mars.

Venom Xenomorph

The Venom Xenomorph from Aliens vs. Avengers

In Aliens vs. Avengers, the Venom symbiote became a key anomaly during the Xenomorph invasion of Earth and resulted in a uniquely dangerous Xenomorph hybrid, nicknamed the Venom Xenomorph. It first revealed its importance when it saved Miles Morales from a facehugger, overriding the parasite and demonstrating that a symbiote could disrupt the Xenomorph life cycle rather than be consumed by it. As the Avengers suffered catastrophic losses, a mortally wounded Iron Man ordered an experiment that merged the symbiote with a Xenomorph in a desperate attempt to create a living weapon. When that host was destroyed, Venom abandoned it and bonded with the creature that killed it, the Mr. Sinister Xenomorph. Through this final host, the symbiote gained the ability to dominate and command the alien hive.

Ani-Men Xenomorphs

Reinstöt's horned and tusked Ani-Man Xenomorphs tearing through Archbishop Emoji's robed followers outside his church in Mega-City One

The Ani-Men were talking human-animal hybrids made by Dr. Niels Reinstöt, a geneticist who spliced human and animal DNA in his laboratory in the Alabama Morass, in Predator vs. Judge Dredd vs. Aliens: Splice and Dice. They included a gorilla, a bear, a rhinoceros, a raccoon, and a stag-headed man called Buck, and they captured a crashed Predator whose trophies included a Xenomorph skull. Reinstöt grew Aliens from DNA in the skull and called the Ani-Men only a small step in the right direction, because he believed Xenomorph DNA would give him genetic perfection.

After the Predators wiped out the Ani-Men's village, Reinstöt escaped with Archbishop Emoji aboard the hunters' ship, its cargo hold full of Xenomorphs with horns and tusks grown from his Ani-Men. The ship landed outside Emoji's church in Mega-City One, and the hybrids slaughtered the cultists gathered there. Judge Dredd, Judge Anderson, and two Predators tracked the rest through the city, killing one that attacked a street dealer and fighting an elephant-like hybrid on Level 53. In a hive under an abandoned reclaim site, a horned hybrid impaled one of the Predators with its tail before Dredd burned it with incendiary Lawgiver rounds, and he then killed Reinstöt, who had turned himself into a Queen.

Mega-City One Queen

The Mega-City One Queen from Predator vs. Judge Dredd vs. Aliens: Splice and Dice

Dr. Niels Reinstöt was a gene-splicing mad scientist from Mega-City One. Prior to his interaction with any Aliens and Predators, Dr. Reinstöt once claimed he was with Mega-City One's Department of Disease Eradication, and informed City Orphanage BD36-30 that each orphan was to receive a mandatory vaccination against Rad-pox. Dr. Reinstöt created a Predalien and Xenomorph Hybrids via gene-splicing and joined forces with Archbishop Emoji. Finally, he transformed into a Xenomorph Queen when injecting himself with a concoction of Xenomorph DNA he extracted from the skull. You could not make this stuff up. Dr. Reinstöt was included in the Predator vs. Judge Dredd vs. Aliens comic.

Anchorpoint Xenomorph

The Anchorpoint Xenomorph from William Gibson's Alien 3 comic

The hybrid from the outbreak on Anchorpoint was a special breed of Xenomorph that only appeared in Pat Cadigan's book of William Gibson's unused Alien 3 script, later a comic as well. In this story, the Alien lifecycle took a different turn, with eggs emitting spores (similar to what happened in Alien: Covenant) and infecting a host by air. The Alien took several hours to gestate, but instead of being born as a chestburster, it erupted fully grown under the skin of Susan Wells, who was in contact with the spores in a lab accident. The Anchorpoint hybrid otherwise looked similar to a regular Alien Warrior, with a translucent dome and a human skull visible underneath.

Rogue Xenomorph

The Rogue Xenomorph from Aliens: Rogue

The Rogue Xenomorph was a genetic experiment created by Professor Ernst Kleist at Charon Base. It was a creature bigger than all the other Alien types, including the queen. It had reddish skin and spikes all over its body. The Rogue didn't feel much loyalty towards the hive and actually fought the Queen Alien. It lost the fight because the queen was able to outsmart it. The Rogue was featured in the Aliens: Rogue comic book and Sandy Schofield's novel.

Eloise

Eloise from Aliens vs. Predator: Pursuit

Eloise was a female Xenomorph android hybrid with a special relationship with the Xenomorphs. She was created as an experiment and grown in a lab on the planet Sybaris 503. Physically she mostly looks like a human female but had Xenomorph DNA and acid for blood. Her hands were shaped like the claws found on the Xenomorphs and had four dorsal tubes on the back. She had enhanced speed and strength and was able to telepathically connect with the Xenomorphs who considered her to be part of the hive. She was featured in the Aliens: Purge comic and her adventures continued in the Aliens vs. Predator: Pursuit comic.

K-Series Xenomorph

K-Series Xenomorphs from Aliens vs. Predator: Extinction

The K-Series Xenomorphs were created in a secret Weyland-Yutani biolab on LV-742 by Dr. Kadinsky in the lesser-known Aliens vs. Predator: Extinction video game. There weren't only a few individuals but a whole race of gold and silver-skinned Xenomorphs, including a Queen and Praetorians. The K-Series battled the original strain of Xenomorphs and eventually lost, a situation similar to the Red vs. Black Xenomorph war depicted in Aliens: Genocide. Although a few K-Series hybrids escaped the biolab out into the open, they were hunted down and killed as well.

Number Seven

Number Seven Xenomorph from Aliens: Infiltrator

The scientists at Pala station from Aliens: Infiltrator experimented with the Black Goo and accidentally created a new Alpha Warrior Xenomorph, a breed of Alien able to command the others when there is no Queen present. The same room tests produced the striped Drone Monica. This Albino Alien (named Number Seven) had a telepathic link with the others and instructed them to escape from their holding pens at once, by breaking the weakened glass. Number Seven set up a breeding ground in the cafeteria and herded humans to be infected by facehuggers. After successfully infesting the whole station, it was killed in an explosion near the hangar bay of the station when Dr. Timothy Hoenikker and Cruz tried to escape.

Predalien

The Predalien from Aliens vs. Predator: Requiem

Though the Predalien is essentially a Xenomorph born from a Predator, it's often called a hybrid, and there's some truth to that label. It inherits several traits from its Predator host (perhaps even more from other hosts), including dreadlocks like the Yautja, prominent tusks, and a robust, muscular build. Its skin and blood are also lighter, much like the Predators themselves. Among the Predators, however, Predaliens are seen as serious affronts to their species and are typically hunted down quickly. Notable Predaliens include the Xenomorph born from Scar in the second Aliens vs. Predator movie, the Abomination from Aliens vs. Predator (2010), and the Predalien born from the Ancient Predator in Aliens vs. Predator: Primal Hunt.


Conclusion

The Xenomorph hybrids introduced across the Alien and Predator franchise highlight the creative use of gene-splicing to add new, often bizarre threats beyond the typical Xenomorph. By combining Alien DNA with traits from humans, Predators, and other species, these hybrids offer fresh variations on the classic Xenomorph while retaining recognizable features from their hosts. Unfortunately, almost every new Alien movie has introduced a new "bigger and stronger" hybrid creature, straying away from the classic Xenomorphs.
