Lizardfolk

The following information was sourced from Mordenkainen Presents: Monsters of the Multiverse and Volo's Guide to Monsters.
The saurian lizardfolk are thought by some sages to be distant cousins of dragonborn and kobolds. Despite their resemblance to those other scaled folk, however, lizardfolk are their own people and have lived on the worlds of the Material Plane since the worlds’ creation. Gifted by the gods with remarkable physical defenses and a mystical connection to the natural world, lizardfolk can survive with just their wits in situations that would be deadly for other folk. Because of that fact, many lizardfolk myths state that their people were placed by the gods in the Material Plane to guard its natural wonders.
Lizardfolk have colorful scales and exhibit a wide array of scale patterns. Their individual facial features are as varied as those of lizards.
