The Kiroptan were bat-like aliens the size of a large dog. They had scaly black skin, powerful back legs, long ears and black eyes. They were omnivorous, with sharp teeth and indiscriminate appetites.
The Kiroptan was one of the species found on the Vandrogonite Visualiser dug up in Rhiwbina. When Gareth Portland created MonstaQuest, he used the Kiroptan as a monster. One was accidentally created in a mall, where it began feeding on the customers. It was later captured by Achenbrite. (PROSE: Pack Animals)
