Joanna is Percival McLeach's pet monitor lizard and the secondary antagonist of The Rescuers Down Under.



Joanna is very similar to her owner: mean, scary, entertaining, and more intelligent than she's given credit for. She is very fond of eggs and enjoys messing with McLeach by swiping them. However, she is not as anthropomorphic as the other animals in the film.


The Rescuers Down Under

In the movie, when Cody gets caught in one of McLeach's traps, McLeach and Joanna show up thinking they have caught an animal, but when McLeach sees that it was Cody, he tries to blame it all on Joanna, saying that she has buried a big hole in the ground. While McLeach helps Cody out of the hole, Joanna spots a mouse in Cody's backpack and jumps on Cody and causes McLeach to fall in the hole.




As Cody leaves, McLeach and Joanna secretly follow him in McLeach's truck but to their unknown Bernard, Bianca, and Jake hop onto the truck and go with the villains to follow Cody. At the nest, McLeach manages to capture both Marahute, Cody, Jake, and Bianca in the cage in the back of his truck and orders, Joanna, to eat Marahute's eggs so the eagle will stay rare. When Joanna sees the eggs, she tries to eat them, but they will not go into her mouth and feel hard, so she knocks them off the cliff with her long tail, thinking they have cracked, and returns to McLeach, but it was revealed that those were actually rocks and Bernard, who was not captured by McLeach, managed to hide Marahute's real eggs safe from Joanna.


House of Mouse

Joanna makes her appearance in "House of Crime" alongside McLeach which was her only appearance in House of Mouse.




  • Joanna had a compartment almost similar to a dog.
  • Although Joanna is McLeach's pet, it is heavily implied that she is frequently abused by McLeach and that her following her master was primarily out of fear. However, she was particularly vicious with other animals, implying that she was used like a hunting dog by him.
  • Frank Welker not only provided the voice for Joanna but also the voice for Marahute, another female animal character without a human speech.
