As the race to find the Mask of Life comes to a climax, Vezon uses his power to merge three of the Piraka – Vezok, Reidak and Thok – into an unstoppable engine of destruction christened Irnakk (an ancient Matoran word meaning "the end of everything"). Irnakk combines the powers of the three Piraka and is ready for battle with a launcher and multiple Zamor spheres. Can the Toa stop this pawn of Brutaka, or will it triumph and steal the Mask of Life?
