The K'kaan were not as hardy as their ancestors and lacked the claws present among the Unas but did have tough nails which they had to trim. They were both smaller as well as weaker compared to their parent race but were stronger than Humans. Generally, they were no more or less intelligent compared to Humans however their thought processes tended to be ordered and more logical. This made them good problem solvers, however, it also made them poor innovators.
