I might pull the trigger on this one, he looks awesome.
Ahab managed to kill an Engineer. But it was a one sided beatdown for a long while, as the Engineer was manhandling and pulverizing Ahab, broke an arm and a leg, but in the end, Ahab pulled out the upset.
Ahab battles the Engineer:
Whilst further exploring the jungle, Galgo and Ahab eventually, rather accidentally, meet the Engineer face to face. Galgo suddenly flees the scene, much to Ahab's surprise and after a brief battle, the Engineer quickly overpowers him, breaking an arm and a leg. Ahab retreats back into the Perses, the Engineer in hot pursuit. Ahab in a last ditch effort, manages to impale a harpoon into the Engineer's chest. The Engineer, however, is able to tear it out and prepares to finish Ahab off. Just before the Engineer kills the weakened Predator, Galgo returns and shoots him in his chest wound with the Engineer rifle that Galgo had previously found. Ahab finishes the job by setting a Self-Destruct Device, escaping the Perses and blowing up the ship.
After the two witnessed the the Perses explode, Ahab returned to the wreckage and began searching through it as Galgo, confused, tried to tell him that the Engineer was dead. The Yautja then grabbed the Engineer's skull and spinal column, holding it up in victory as he roared. Galgo, now alongside Foster, Chris and Jill, who came to investigate the explosion, said that he was beginning to like Ahab. Foster replied "Yeah, until he kills us next.", but Galgo told her they were too "minor league" for him. As the Yautja walked away, Galgo commented that Ahab "finally got his whale".
