Wolf (Aliens vs. Predator: Requiem)

Wolf is the main protagonist of the film Aliens vs. Predator: Requiem.

Mission
In the beginning of the film, Wolf recieves a distress signal from the ship that had just left Earth, after the events of the first film.The scout ship that had sent the signal, had crashed on Earth, and Wolf leaves his planet, to find the ship. When he arrives there, he discovers the lifeless body of the hunter who'd sent the signal to him. Wolf grieves for the fallen hunter, and then proceeds to take the Yautja's Bio-mask, to find out what caused the ship to crash. It is then, that he realizes that a Predalien from Scar's corpse had escaped, and killed several other hunters on the ship, before it had crash-landed. Now that he knows what had killed the crew, Wolf takes the dead hunter's weapons, along with a dissolving liquid, and uses his self-distruct device to blow up the ship, removing any trace of it, before leaving.Meanwhile, the escaped Predalien has spawned several Xenomorphs, by impregnating humans who get in his path. Wolf is hot on the trail of his target, and uses his dissolving liquid to remove any traces of the corpses he finds. A cop spots Wolf while the hunter is at his work, and  is killed by the Yautja. Finally, after a battle in the sewers, Wolf catches up to his main target in a hospital, and the two creatures clash. During the fight, Wolf accidentally kills one of the women in the hospital with his Shuriken, pinning her to the wall, to the horror of her friends nearby. The Xenomorphs in the building flee to the rooftop, where they are killed by the Yautja. The Predalien battles Wolf, and the two mortally wound eachother. But before either of them can deliver the final blow, The Military bombs the town, killing both Wolf and the Predalien.
