Zoh Shia is a Construct, and the first final boss of Monster Hunter Wilds. She is believed to have been created by an ancient civilization however because of the chimera nature of her creation, they lost control of her and were annihilated. You as the Hunter have found her, the Master Creation of Wylk. It seems like the ancient people of Wyveria must have designed her to be more humanoid, which in hindsight was a bad idea.
