When Tenzin Norgay performed an ancient ritual at a sacred Himalayan lake to seek allies in protecting the Yeti, the waters mysteriously connected to the Congo Basin, awakening the ancient Mokele-mbembe to its shared purpose with all cryptid guardians. Through this mystical aquatic link, the prehistoric creature pledged its service to the Whiteout Guardians, offering its primordial wisdom and ability to manipulate water and mist to shield the Yeti's domain from intruders.

The Mokele Protector possesses the ability to manipulate water in all its forms, creating dense fogs and snowstorms that obscure the Yeti's tracks and confuse those who would hunt the creature. Its ancient dinosaurian consciousness can project across vast distances through waterways, allowing it to witness events near any body of water and communicate warnings through the rippling of lakes and streams. Though physically bound to the Congo Basin, its spiritual essence can manifest as a translucent, blue-green apparition in the Himalayan mists, often mistaken by climbers as a trick of light or altitude sickness.

The Mokele Protector serves as the Whiteout Guardians' early warning system and environmental defender, using its control over water to create natural barriers against intruders while also serving as Tenzin Norgay's mystical advisor on matters concerning the ancient connections between all of Earth's cryptid species.
