Physiology
The Excel were a sentient species that belonged to a unknown subgroup, but evolved from insectoids and humanoid hybrids. They have similar physiology to humans, with many exceptions.

Excellians were bipedal and at times quadrupedal meaning  they walked on two legs or four depending on the subspecies. Unlike humans and other species they have an exoskeleton on the outside, that protects their valuable insides from harm. Their exoskeleton is stronger than other Insectoid species, even strong enough to resit lightsaber and blaster bolts. Their anatomy was similar to humans minus wings and exoskeleton.

Excellians were endothermic meaning that they were warm bloodied, they are also Carnivores meaning they require    animal fibers
