The Lizard, also known as IGUANA in the NES version, is an enemy in the original Final Fantasy. It is a challenging enemy if your party has not been sufficiently trained up, but if the player has trained them properly, they should have no problem killing this beast. They appear near Pravoka and Matoya's Cave, where they may pose a threat for an under-leveled team, and near Mount Gulg and outside of the Citadel of Trials.
