Kroxigor

Think of a typical Saurus warrior, now beef him up even more and make him more obedient, then you basically have a Kroxigor. They make up the brute strength of the Lizardmen races, used for construction, bodyguarding, and being strong warriors, though their lack of intelligence typically prevents them from being in charge of anything, and they usually just take orders from a Saurus or even a Skink Chief.
