In the film's climax, Naru uses her deep understanding of her environment and her enemy's hubris to orchestrate the perfect trap. She recognizes a fatal flaw in the Predator's technology: its projectile weapons strictly follow the laser targeting system built into its bone mask. Using the French trapper's flintlock pistol, Naru baits the heavily wounded Predator into a sinking mud bog—the exact pit she herself barely escaped earlier in the film.
She consumes the Totsiyaa flower to completely hide her heat signature, ambushes the creature, knocks off its targeting mask, and strategically positions the mask in the mud aiming directly at the bog. When the enraged Predator blindly fires its deadly metallic flechettes at Naru, the projectiles track the laser from the stolen mask, looping around in the air to shoot the Predator directly through its own head. This brilliant twist pays off the film's running theme of Brains over Brawn. Naru then decapitates the creature, paints her face with its glowing green blood, and returns to her camp. She tosses the severed head at the Chief's feet and is rightfully honored as a War Chief.
