The Mandallian Giants represented a race of towering, powerfully built humanoids, exceeding even the size and mass of Wookiees.
A notable characteristic of their physical form was their reptilian appearance, distinguished by green scales covering their bodies. Their heads featured prominent, pointed, fin-shaped ears, while a lengthy, tusk-like bony plate acted as protection for their face. Inside their mouths, they possessed rows of jagged teeth, accompanied by a pair of sharp fangs that extended from their upper jaw.
Due to their considerable size, the Mandallian Giants were not known for their speed.
Individuals belonging to this species gained recognition throughout the galaxy for their martial prowess, with many receiving combat training from a young age, transforming them into formidable warriors. They were considered among the few races to have withstood a full assault by the Mandalorian Crusaders. Their resistance to conquest and dedication to battle earned them the respect of the Mandalorians, who integrated many Mandallian Giants into their ranks. From that time onward, they participated in numerous wars of conquest alongside the Mandalorians. They were known to be open to fighting anyone who challenged them.
Chewbacca encountered a Mandallian Giant working as a casino bouncer while on board The Wheel around 0 ABY, but he overcame him with relative ease.
