Karasar

History
Originally a species of early mammalians, the karasar were uplifted and bio-engineered by an ancient unknown alien species to act as a warrior caste in their conflicts. They were utilized in many wars and were augmented to survive grievous injury that would likewise be fatal to their initial form.

Their new forms were made to be large, muscular, intelligent tactical thinkers, but not independent, requiring a more specialized type of karasar, who can be differentiated by their predominantly black hair and larger physique. The lowest caste had brown or orange hair, while the leadership caste were those karasar who had evolved over their lifetime to become such and not a separate genus.

However, their masters suffered a devastating attack at the hands of their enemies, nearly wiping them out in the process. Those few that remained set the karasar back to their home system, knowing they were incapable of fielding such armies anymore. Now alone for thousands of years, the karasar developed a new way of life and thinking, evolving beyond their initial purpose and into their own species.

Physiology
Karasar appear similar to the extinct Earth animal Lystrosaurus, albeit with a more broadly humanoid body shape in a standing up walking style. In their earlier years, the karasar's genetics were manipulated by an unknown civilization to act as soldiers in their war and making them more well suited for combat and their other designated functions. Most of their body is covered in a thick hide, with noticeable patches of hair that vary in colours, depending on what their genetics dictate they are best at.
