Species Location Weapon Abilities The leaper lizard (also simplified to leaper) is a mount used in Jak 3. They are creatures native to the Wasteland, where they are eventually corralled and domesticated in the leaper lizard pen, and then trained to be used as mounts as the main mode of transportation in Spargus. In addition to feeding on the local rodent population, they are sometimes used for recreation and sport such as leaper races. Once in the Great Volcano, Jak captured and used one to find the satellite inside. It was apparently left over from a failed Precursor monk expedition.
