Batty Koda is one of the main characters in FernGully: The Last Rainforest. He was voiced by Robin Williams. He mainly lives in the rainforest with the Fairies of Ferngully after escaping from a biology lab. Batty is depicted as a thin, large headed Australian fruit bat with big yellow and red eyes, large ears, a pig-like nose and a clearly visible antenna in his head. His main body is brown, with large black wings and black feet, along with light brown hair on top of his head. During his musical number "Batty Rap", we can see green and red wires hidden in his left wing. Koda is a mentally unstable creature, yet is the comical relief character in the film. We also learn that he cares for his friends. Because of the antenna implanted by human scientists in his head, he often receives electric shocks. During his introduction to the fairies, he describes himself as a "...nocturnal placental flying mammal of the order pterodidae... ", which is the true taxonomic classification of megabats (Giant Bats). Maybe he learned that, and much other information he knows (like the concept of deforestation and other stuff) in the biology lab, in which he was being tested by cosmetologists and other cruel scientists. In the movie, after initially being afraid of Zak, the human, he seemed to just become indifferent towards him until the end of the movie where Zak becomes one of the rare humans Batty learned to like and trust.
