were eaten by giant frogs (saying that "sometimes, you can't let the fear get in the way of what you've got to do!"). Iggy (Robert Mark Klein) is a Castilian iguana with a slightly excitable personality. He thinks himself to be bigger than anyone else, but always gets ahead of himself. He and G'Bubu were the first to befriend Alex and Zoe when they first arrived and are always on hand to help their new friends with any problem. He also has romantic feelings for Zoe. Later in the series, his voice has been changed. In "Don Iguana", he tries to prove his bravery to Zoe by disguising himself as Don Iguana, D'Avenger of Animalia. He can camouflage and change the color of his body due to being part chameleon via his grandfather. Livingstone T. Lion (Chris Hobbs) is the youthful leader of Animalia and the Keeper of the Core.

Tyrannicus (Dean O'Gorman) is a sly smooth-talking tiger who serves as the main antagonist, Tyrannicus feels he should be ruler of Animalia rather than Livingstone. He finds ways of getting ahead by the use of various get-rich-quick schemes. He despises Alex and Zoe, who
