Keith Childs (Earth-7149)

"That's a crock-a-shit."

Keith Childs was a lead mechanic contracted by the Concordance Extraction Corporation and stationed aboard the research and mining outpost Con-Am 27 alongside his assistant Robert Palmer. In 2557, Palmer and his crew became involved in surviving a small-scale xenomorph outbreak at Con-Am 27 alongside Ellen Ripley, as they were stalked and killed by a pair of xenomorphs one by one.

Finding Ripley
In Winter 2557, explorer Matias Jernigan crash-landed his D81-LRT Condor nearby the Concordance Extraction Corporation mining outpost Con-Am 27, where they were killed by the camp's commander, Barrie Montone, who attacked them in self-defense after thinking they had gone crazy. Afterwards, Norris and others rushed to extinguish the blaze from the explosion of the Condor and help carry Jernigan's to the laboratory. Hours later, during the fall of the evening, Dr. Marian Lazarus and pilot Ryan MacReady returned from their investigation to the nearby stranded freighter CMS Mimir, from where Jernigan came from, with a woman, Ellen Ripley and an Ovomorph.

"Somebody in this station ain't as well as they think. Right now the thing might be inside of us. By Spring, it could have taken all of us. So, how do we know who's fine? If I was impregnated, how would you know it?"

- - Ellen Ripley and Keith Childs Hours later, Childs was awakened by Ripley once she witnessed a xenomorph killing MacReady at the outpost's dog kennel. He arrived just in time to witness MacReady being mauled alive. Childs almost killed the alien with an M7057 flamethrower, but the creature managed to escape and later kill George Bennings. Childs, alongside the rest of the personnel and Ripley, was drawn to the laboratory, where they discovered the blood locker and its samples had been destroyed by the xenomorph, which prevented a possible blood serum test from discovering who had been impregnated by a Facehugger, creating paranoia and leading Ripley to lock both Barrie Montone and Dr. Lazarus after suspecting of them.

After Joel Fuchs, the last biologist, went missing during a deliberate power outage caused by the xenomorph, Ripley organized a search party to locate him while assigning Palmer and Victor "Windows" Waites together. Palmer disagreed with her decision, stating he wanted to go with Childs, which led to another argument between between the crew. Ripley then left Childs, Vance Norris, and Palmer at the outpost while she and Tyler Nauls went to investigate the exterior of Con-Am 24. Forty minutes later, Ripley, however, was able to return to the outpost without a guide line, and broke into the storage room, where she threatened to kill the crew with an M9 fragmentation grenade. During the ensuing heated debate, Norris suffered a heart attack, prompting a nervous Lazarus to revive him with defibrillation, aided by Ripley.

However, Noriss' chest was violently torn by a Chestburster, who violently tore Lazarus' chest with its jaws, leading the doctor to quickly die from blood loss. To determine if anyone else was also impregnated, Ripley improvised a rudimentary blood test using a heated copper wire and samples she took from the crew. After noticing the Chestburster's behavior, Ripley theorized that the creature would attempt to flee from a host if harmed. Before she could start the test, Grace Trantor, in an act of mutiny, attempted to stab Ripley with a scalpel, leading Ripley to shoot her in the head in self-defense, prompting the rest of the crew to agree with the rest. Before she dipped the heated wire into the petri drish with Palmer's blood, they were stumbled by the Thing, who jumped out from the ceiling, decapitated Palmer and slashed Windows in the chest with its tail, before Ripley was able to burn the creature with an M7057 flamethrower.

After Childs was proven to be clean from impregnation, he was ordered by MacReady to guard the main gate of the station while they went to perform the test on Dr. James Blair, but while he was unaware, he was killed by the Kamchatka Queen without noticing.
