Megalania
Megalanias, like their smaller cousins the giant monitor lizards, strike fast and use their powerful bite to grip their prey. They prefer to swallow their prey whole rather than risk others getting a bite of a hard-won meal.

Source Monster Core pg. 224Lizards have a wide range of appearances and abilities, but most share a basic reptilian shape—long tails, wide toothy mouths, and four legs. While a few species are capable of movement on two legs for short periods of time, most are strictly quadrupedal. The three species presented here represent the most common and well-known of the larger species.
Lizard Locations
Giant lizards can be found in all temperate or tropical climates, often in relatively close proximity to smaller villages or rural regions where they can be a dangerous threat to livestock or travelers. The two lizards presented here tend to dwell in warmer regions— jungles for
giant chameleons and savannas for
megalanias.
Lizards and Lizardfolk
Giant lizards are often used as mounts and guardians, or kept as pets, but they are most often and traditionally kept by
lizardfolk. The kinship these people share with giant lizards is unmistakable, valuing their companionship to an extent that equals or even exceeds that which other societies have for popular animal companions like dogs and horses.
Other Giant Lizards
The three species of giant lizard presented here are but the most common of their kind encountered in the wilds. Stories of much larger lizards persist, including the 20-foot-long megalania, a truly enormous version of the giant monitor lizard capable of swallowing creatures whole. Less dangerous is the giant chameleon, although its ability to blend into its environs makes it a much more insidious and stealthy threat than the lumbering, mighty megalania.
