|First appearance||The Kur Stone:Part Two (flashback)|
Mokele Mbembe are cryptids that are said to be a living fossil. They were first seen in a flashback in The Kur Stone:Part Two.
Reports tell of a creature that resembles a living sauropod (long necked and extremely long tailed dinosaurs such as Brachiosaurus, Brontosaurus, and Diplodocus). Seen in a flashback in The Kur Stone:Part Two and Kur:Part One. They also appear in War of the Cryptids as a part of Argost's army. This cryptid supposedly lives in the Lake Tele region in the Congo. In the end of the war, the Mokele Mbembe was chased away by the Grootslang.
- In War of the Cryptids, Mokele Mbembes are shown walking on their hind legs fighting with Argost. Although real sauropods could stand for a while on two legs, they had to walk on all fours.
- Unlike most sauropods, they spend most of their time in water. They don't eat humans, but will quickly kill those who disturb its territory.
