While Batman may be no stranger to aliens, both friendly and villainous, there are few he has encountered that are more deadly than Aliens' Xenomorphs. On several occasions, DC Comics and outgoing Aliens comics publisher Dark Horse have come together to pit the Caped Crusader against the horrific space monstrosities, with each appearance bringing a new and deadlier threat against him.
Now, we're taking a closer look at the three separate miniseries where the Dark Knight went head to head this these acid-burning, chest-bursting creatures.
Batman/Aliens
The Dark Knight first encountered these creatures in 1997's Batman/Aliens by Ron Marz and Bernie Wrightson. While searching in the Guatemalan jungle for a missing Wayne-tech employee, Batman comes across a special forces group investigating a crashed spaceship. Upon searching it, they find three Xenomorphs, and even though they manage to kill one of them, only Batman and two of the operatives make it out of the ship alive, escaping into a nearby cave complex. After finding a possible escape route, they encounter the remaining two aliens, and Batman manages to kill one with an explosive.
They find a possible exit in one of the cavern's ceilings but one of the operatives, Hyatt, stuns Batman and allows the other agent to get carried away by the remaining Xenomorph. She plans to kill Batman and return later with a larger group to collect the alien eggs and use them for biological warfare. Unfortunately for her, a Facehugger had laid an egg inside a crocodile, resulting in a gigantic Xenomorph that proceeds to kill her before she escapes. Batman manages to drop both the Xeno-Croc and the remaining alien into a nearby lava pit, He blows up the ship, and destroys any evidence of the Xenomorph's existence.
Batman/Aliens II
In 2003's Batman/Aliens II by Ian Edginton, Stanz Johnson, and James Hodgkins, builders discover a buried laboratory under Gotham that contains a pure white Xenomorph. Batman discovers that over 70 years prior, a man had found an alien, taken it to this lab in Gotham and allowed himself to become its host. Batman tracks them into the subway and manages to blow most of the creatures up, saving three civilians with Facehuggers attached to them. At the hospital, after the Xenomorph spawn are removed from the victims, the original white alien breaks in and tries to escape with the recently-extracted offspring. Batman and the GCPD chase after it and manage to kill one of the baby aliens, but it manages to get away.
Once the youngsters are fully grown, they head for Arkham Asylum, with Batman in hot pursuit, this time armored up and holding one of Mr. Freeze's guns. With the help of Two-Face, he kills the two young aliens and freezes the original to death, before being knocked out by a shady government operative named Doctor Fortune. After being kidnapped, Batman realizes that Fortune was splicing together Xenomorph and human DNA, and has done so on some of his worst enemies, including Poison Ivy, Mr. Freeze, and the Joker. Fortune pits them all against the Dark Knight, but he defeats them and escapes to confront her. During the standoff, a clone hybrid of the alien and Killer Croc is released and kills Fortune. Batman escapes, and military helicopters arrive on the scene, destroying any evidence that may have been left over.
Batman and Superman Vs. Aliens and Predator
By Mark Schultz, Ariel Olivetti and Todd Klien, Batman and Superman Vs. Aliens and Predator shows the two heroes encounter both deadly alien species in the frozen mountains of Peru. After convincing the Predators that Superman is a sun god and that Batman is his emissary, they discover that they have been living there for thousands of years, cut off from the rest of the world. The heroes decide to help them get home, with Superman transporting them into space using miniaturizing technology from the Fortress of Solitude.
As is their nature, the Predators turn on their saviors, and it is revealed that they have an Alien Queen hidden on their ship, with Batman briefly having to fight it single-handed before Superman intervened. Eventually, they manage to incapacitate both species and send them back off into the stars, with the heroes unsure if, or more likely when, they will return.
