Rikuai is a legendary beast of the underworld, he is the main antagonist of the Short Soyuzmultfilm, Legends of the Peruvian Indian. Rikuai has an unusual appearance - it is an animal with clawed paws, a toothy mouth, large eyes, a long crest over its head and a second head at the end of a long tail. Rikuai does not look like any existing animal. That's why archaeologists called him the beast of Rikuai.
