The Mad Unicorn lizards - (Tyrannodon Monocornius) - are a species created when Dr. Llewellyn Van Scolex created a mutated reptile and left it alone. The creature escaped from his lab and mated with a native lizard, hatching two strange lizards with 15 cm horns, one male one female. Eventually they multiplied over the years creating a population of 22 million all over the state of Vantrapolis.

Many people consider the Unicorn lizards loathesome parasites because they feed on crops and farm animals. But without the Unicorn lizards there would be a massive gap in the ecosystem since many creatures have adapted certain features to survive through the Unicorn lizards' attacks and without the Unicorn lizards these features would be rendered useless.
