I originally posted this in the Worst AVP stories thread, but I felt like it needed to be here, too, just 'cause its funny.
Aliens vs. Predator: Resurrection
After Dallas, Ricky, and Kelly escape Gunnison, they are put into custody by the secretive Yutani corporation, and held pending termination (they do know too much, after all).
The Yutani corporation then enters into a business alliance with the Weyland corporation, who has recovered enough tissue from Scar to clone him, with the help of recovered Predator technology - and with the PredAlien embryo still inside of course.
The PredAlien, after maturing and being gawked at by WY scientists, inevitably escapes, and wreaks havoc throughout the base. Just when all hope seems lost for the three Gunnison survivors, however, they are rescued by Alexa Woods, and they track the PredAlien, with the help of a clan of Predator warriors, through New York City, where it's leaving a path of mangled corpses and building its army of alien warriors.
And, of course, because this version of Chet was crossed with Predator DNA, he would then partake in the Predator reproductive system, and gives birth to this bad boy from out of his vagi-er, mouth:
The 'PredBorn', who is of course highly intelligent and uses weapons, then organizes the aliens (after killing Chet2) into taking over the united states. They're stopped, however, by Ricky Howard, after the startling revelation that he is in fact the first Synthetic.
