Originally dwelling in Australia's billabongs, this massive creature sensed the awakening power at Loch Ness and traversed the world's waterways to reach Scotland. Its arrival coincided with unusual tidal patterns and unexplained seismic activity, drawing the attention of Dr. Blackwood and her fellow Seekers.

The Bunyip Behemoth possesses the ability to manipulate water currents and generate localized storms. Its massive form can compress to navigate narrow waterways, and it emanates a low-frequency hum that affects electronic equipment. The creature's presence causes water to become unusually dark and opaque, making it nearly impossible to photograph or track using conventional methods.

Acts as a harbinger of major cryptozoological events, its presence indicating the imminent revelation of ancient secrets. The Bunyip Behemoth serves as both a challenge and an ally to the Seekers, testing their resolve while providing crucial clues about the true nature of water-dwelling cryptids.
