When Wolf kills a Xenomorph Warrior, an enraged Predalien comes and fights him. The Predalien stabs Ricky and flees when Dallas, Ricky's brother, shoots it. During the battle Ricky's love interest Jesse was killed by Wolf unintentionally, so he shot Wolf several times and he was knocked down the elevator shaft by a Xenomorph. It is injured and orders three Xenomorphs to fight Wolf. The Predalien invades a hospital and implants embryos into pregnant women. In the process, the Predator's plasma cannon wildly fires a shot into the sewers and the Xenomorphs gain access to the town. Wolf follows the Xenomorphs and a battle ensues. A second pregnant woman named Carrie is brought to the Predalien and implanted with embryos. The Predalien enters a kitchen and murders the cook. The Predalien attacks him and allows the other Xenomorphs to escape. Wolf then comes and starts killing the Xenomorphs in the sewers. The Predalien then attacks some homeless people in the sewers, implanting some Xenomorph embryos in a pregnant mother. One Yautja, before dying, sent a picture of the Predalien to another Yautja, called Wolf, who went to Earth to kill the Predalien. It sneaks into a scout ship and kills the Yautja there, causing the ship to crash on Earth. In the sequel Aliens vs Predator: Requiem, the same Predalien has matured into an adult. When Scar was killed by the Antarctic Queen before she was dragged into the ocean and the other Yautja took his corpse into the ship, the Predalien Chestburster burst from his chest. Two of them, Celtic and Chopper, were killed by a Xenomorph known as Grid, and Scar was implanted with a Xenomorph embryo by a Facehugger.

In Alien vs Predator, three Yautja landed on Earth to hunt Xenomorphs.
